triple crossfire HD3870's help OC

[RoachHotel]

I have 3 HD3870's crossfirex'd and am only getting 12963 score 3dmark06. If I go with 2 cards crossfired I get 12372. Damulta sais I am cpu bottlenecked, its a AMD6400. He also sais I need the bios to unlock the video cards. If anyone has it I need a benchmarking overclock, and a Stable overclock. Damulta also said I am using shioty Vista.. LOL

Now if I overclock the cpu to 3.5 which is stable on my machine, I get 13950 3dmark06 scores. I am new to overclocking, only been doing it about a month.

My system.
AMD 6400+ black edition
Asus M3A32 MVP wifo
Crucial ballistix tracer PC 8500
3 HD3870's
Ultra 750 p/s
Antec 900 case
I am only air cooled at this point also

Damulta also sais he is alive, but still drunk from last night.. LOL

Thanks,
Roach

[cdawall]

well 3.5ghz is a really good oc on the 6400 you might be able to push 3.7ghz with a large amount of luck but i doubt it.

could you fill out your sys specs under user cp it makes it alot easier to hepl so we don't have to scroll up to the 1st post constantly as teh thread gets larger

[erocker]

What O/S are you using, and what drivers are you using? How do you have your crossfire bridges setup? DaMulta's a great guy! Welcome to the forums!:toast:

[cdawall]

he said he was on vista

[RoachHotel]

I have had this chip to 3.710. I am also sure with some more voltage I might get 3.8 out of it. I did that in Win XP, now that I am in vista its being a bit more touchy. Also I got the 3.710 with only 1.45 volts. Damulta knows more then I do, I am still learning.

[cdawall]

well shit leave it @ 3.71ghz thats a really good oc for air!

[RoachHotel]

Well, the internal connector are a great question. Which time. LOL. I have moved them a few times with little change. I have had the connectors from card 3 to card 1, then card 3 to card 2. Then from card 1 to card 2, card 2 to card 3. The scores are identical with those set ups. If I go from card 3 to card 1, then card 2 to card 1 I get an out of range message.

[erocker]

http://img.techpowerup.org/080413/untitled.jpg I guess that's the way it's supposed to be. I think a Phenom 9850 will help your situation. Are you using two of the cards in the blue slots and one in a black?

[RoachHotel]

Yes I am using 2 in the blue and 1 in black, which gives me 16x on 1 card, and 8x on the other 2. I did have it set up that way.

[erocker]

Quad core needed I think. I'll be testing my trifire/quadfire setup next weekend so I'll see how that goes. I'm using a 5000+ B.E. so we can see how are scores match up.:)

[RoachHotel]

That great.. I a saving for a 9850, and some H2O. It will be awhile on the water, but i might have enough for the chip next week. Also I found a cpuZ shot of a little slower clock I got on XP. I'll try and post it.
Thanks erocker.. big help so far. Thank you.

[lemonadesoda]

FYI, I get 11000 on 3dmark06 with a HD 3850 AGP. So 3x 3870 on PCIe giving 12000 is AWEFUL.

[RoachHotel]

Actually overclocked I scored 14530 with 3. Can't truly compare intel q6600 to AMD 6400. Theres a difference between brown nosing, and just plain ole being appreciative. Thank you for helping me e. I will be interested in seeing your scores with the new proc. After talking to Damulta he feels the same way, the newer quad proc will make up alot of the difference.

Any other ideas let me know. And if I find anything I will post back to.

[ShadowFold]

That score is a little unusual. People on the 3dmark thread are getting 13000 with a single 6000+ and 14000 with two 3870's and a 6000+. And I my self get around 9000 with a 2.5ghz E2200 and 12000 at 3.2ghz, both with a 3850 so you should be getting alot higher. What drivers are you on? Try and roll back to 8.2 or 8.1 if you can cause 8.3 is terrible(well at least for me and a few others)

[erocker]

So, what's your two card crossfire score using the 6400+ at 3.5ghz?

I think, for triple/quadfire, you need 8.3's and Vista, which do seem to work well together. With crossfire and XP 8.2's are a must.

He is hitting 14k almost.

I only hit 13k with CF and a AMD Chip


That's a great score for what he has, it's the dual core AMD prog that is holding him back.


What he needs to do for now IMO is oc the crap out of the video cards.


Does anyone have the unlocked bios?

[RoachHotel]

damulta knows. I am right at or just above 14k overclocked to 3.5 with 2 cards. But it seems having 3 cards is almost a waist. Or is it? Im not going to pick up that much from the one extra card, compared to a better processor and overclocking the 2 vid cards.

Sheesh, I better call Damulta again.. lol..

[erocker]

If you don't have the extra card already, I wouldn't bother picking another one up as it will run on a slower PCI-E lane anyways. If anything see if you can find a used 3850 on the cheap to stick in there.

* I think DaMulta needs his sleep. lol.

What are your video card clocks?

[RoachHotel]

Very interesting graph. And very helpful. Thanks. My framerate in cod4 is right around 150 pegged all the time. It was that way with 2 cards and stayed that way with 3 cards. I have my max fps in game set to 200.

[RoachHotel]

They are at 825 each. memory is standard.

I was also wondering, how do I use ATi tool and catalyst? do I keep catalyst at default, then use ATi tool to change clocks?

[RoachHotel]

I didnt think so, and the 3rd card doesnt seem to be making a whole lot of difference anywhere. Benchies, games ect..

Also an earlier question, I am running the 8.3 drivers.

[DaMulta]

take a ss9(screen shot) with device manager showing all of your cards.


Other than that I would say your CPU is maxed out and you need a quad, but that will only help in certain things....

Whats the problem here?

[DaMulta]

Sleep on my side....drinking till 5Am and getting a phone call at 12noon doesn't help LOL....


Take a SS of what you have going on in taskmanager. What do you have running in CCC?

[DaMulta]

Quad runs 3dmark06 better.

I have SS somewhere here on the tpu...hmmm where would they be.

[DaMulta]

A phenom would actually make things worse since they cant be clocked to 3.5ghz. The phenom might get a higher cpu score, but the game tests would be even more cpu limited than they are already.

The x2 and the phenom are not the same chip....they are made differently.


Show me where a phenom works clock for clock with a X2 CPU.

[RoachHotel]

Hey its not my fault I called you at noon.. lol..

[blkhogan]

Hell, I felt good breaking 10,300 with a 5000+ @ 3.2 and a 3870 Toxic @ 800 / 1155MHz :) But these numbers make me feel sad :(

[cdawall]

thats not 100% true the new 9850 gets pretty close to that on air...

[Bytor]

I have a 9850 BE on order and I'll post some benchmarks then.

[Bytor]

What tab in Task Manager I'm I SSing?

[DaMulta]

[philbrown23]

I have 18k with 2xhd3870's in 3dmark 06, but I'm also running a very high cpu oc and for me when I u my cpu the cards get higher scores to it's almost as thogh the scale with it. soon I'll show yall some tri-fire/intel benchies.

[RoachHotel]

Here are a couple SS showing my device manager and processes, if this helps also.

And if anyone out there has 3 3870's running in crossfirex, I would like to know how you have your internal crossfire cables hooked up. I have heard at least 4 different ways, also I cant find anything on the net that shows "The right way". hehe.

thanks guys.

Is that with two cards or three?

[RoachHotel]

Phil youre running an intel. My AMD cant run those numbers. I havent seen any amd's that can run that in 3dmark. I know the video cards can, but the proc cant.

[RoachHotel]

I only have the 2 cards in there now.

[RoachHotel]

You want me to install the 3rd, and do it again?

[RoachHotel]

I will be back in a few. I will install the 3rd card again. Take a pic of my system so you can see, and a SS of device manager, and Catalyst control center. It will take me a few.

[erocker]

With two, the device manager looks good.

[Bytor]

So what are you looking for in these screens?

http://i25.tinypic.com/33ur0uo.jpg

[cdawall]

well for one it still only sees 2 cards?

[Bytor]

Thats all I have installed right now. Even if I had 3 I don't think XP would see more than 2.

[RoachHotel]

Ok E. Im sorry you might have to fubar my pics of my system, they are pretty big. but its how I have it set up. .After I post this, I will run 3dmark and see what it does again.

crap, cant get the pic small enough. but I have the internal cables from card 1 to card 2, card 2 to card 3. Like in your earlier post e.

[RoachHotel]

ok 3dmark score after installing 3rd card. But my proc is overclocked to 3.5.

[RoachHotel]

sheesh, its too big to post.. Anyway its 14369. 3 3870's and cpu overclocked to 3.5.

[Bytor]

Wow maybe I wont add a 3rd 3870. Thought it would score alot better than my 14686 on 2 cards.

[erocker]

What is your CPU score?

* A Phenom 3850 at 3ghz will give you just over 4000 cpu points in 3d06 and increase your other scores as well.

[Bytor]

My CPU score was 2745 at 3.553 ghz.

[trog100]

to see much of a score increase with three cards in 2006 it needs an intel chip at 5 gig or so..

quad cores wont scale any better than dual cores.. no matter how many cards u have the cpu score will remain the same with one card or three cards.. pure core speed will make it scale better hence the need for the intel at 5 gig stuff..

three cards is a waste of space unless u want to break records and have the fast intel chip to go with it..

2006 is a bunch of single threaded game tests and a multi threaded cpu test.. as someone said earlier a slower quad would score more in the cpu test but less in the game tests.. my intel dual at 4 gig will beat any phenom in 2006 with one of its cores switched off..

how about 15K in 2006 with just one core running.. i would get a poor cpu score but the game tests would make up for it relative to a slower amd quad..

trog

ps.. i just ran it and proved myself wrong.. he he.. 13500 with just one core running.. the cpu score was 1992.. the game tests did lose a bit with just one core running.. about a 1000 points.. i didnt expect em too.. with both cores running my C/F 2006 score would be around 17k... with one card around 13K..

[Kei]

Trog, what is your cpu score in 3dmark06 if I may ask. I'm very curious to see the score breakdown on one of your runs when running a single core, can you do a run and post a screen shot?

I've broken the 13k mark now with my 3870 and Phenom 9850 but it took some tweaking of the clocks on the video card to get it. I'm not done by any means but I've broken 13k on a single card now. When I was using the 8800GT OC tweaked my last score with the 9850BE was 13,354 marks before I took it out of the box. Not sure what I could get if I had kept tuning with it.

Here is a link to my single card score with a Phenom 9850BE at 3Ghz (daily clock on stock 1.30volts 250*12).

[RoachHotel]

Well damulta that post by Kei sums it up. With a 9850 cranked up a little, that will boost my scores alot. Considering I am getting around 14k now.

So you guys know, I installed my 3rd card again, and it may not make a big difference on the charts, but it most definatally makes a big difference in game. I had a noticable frame rate increase in COD4 with the 3rd card compared to just 2 cards. 3Dmark doesnt show the 3rd card improvement.
Now a bigger question... Will Vista 64 bit do any better then the Vista 32 I am using?
Goodnite guys.. great help from everyone. Thanks

[erocker]

And gaming is where it counts.:toast: The Phenom will help with your 3d06 scores (if you're into that kind of thing). Vista x64 will help you with more memory in your system if you choose to do so. I've heard some complain that it's buggier than the 32-bit variant, but if you already have 32bit Vista, upgrading to 64-bit isn't going to help in games or benchies or anything. The more power the better I say:rockout: Though, some people around here are rather conservative, cough trog, cough! But that's all good too! Trog knows his stuff!:toast:

[TonyStark]

A quick way to check if you are CPU bottlenecked is to run the tests at higher image quality settings. At low image quality settings, the video cards render each frame faster than the CPU can send information ....

Try the following tests and compare results of each test:
Test 1:
1 Card
Max resolution of your monitor
4xAA / 16xAF


Test 2:
2 Cards crossfire
Max resolution of your monitor
4xAA / 16xAF


Test 3:
3 Cards crossfire
Max resolution of your monitor
4xAA / 16xAF




You'd likely be CPU bottlenecked in games also if you run them at 1280x1024 with no filtering. But who the hell does that?


I have 3 HD3870's crossfirex'd and am only getting 12963 score 3dmark06. If I go with 2 cards crossfired I get 12372. Damulta sais I am cpu bottlenecked, its a AMD6400.

[RoachHotel]

Ok, I just noticed most of you guys have your video cards clocked to the hilt. I think that may help me some too.
I think getting an AMD chip to bust up some of you intel guys is whats driving me, lol. I know us AMD guys dont have a chance on the benchmarks but its fun trying.

Does anyone have the proper bios to volt the 3870's so I can get them overclocked better?

[Nitro-Max]

I still think its more to do with your cpu tbh.

[RoachHotel]

I think you and everyone else is right..

[trog100]

its a resolution and game setting thing.. 2006 is way tooo f-cking old.. the settings and resolution used in the default game tests simply dont load the gpu enough.. this applies with any grafix tests..

drop the resolution and game settings and it ceases to be a grafix card test and becomes a cpu test..

2006 at its low grafix card default load wont scale without the super cpu.. but increase the resolution and AA/AF way up and it will scale nicely even with an amd cpu..

for an example i ran the crysis bench at its low settings at 800 x 600.. one card scores 187 fps two cards score the same 187 fps.. and with just one cpu core running it wouldnt be far behind.. there aint no special multicore cpu test in that one to paint a false picture..

cod 4 would do the same at very low settings.. basically any f-cking game will become will become cpu limited if the settings and resolution are low enough.. one card.. two cards or four cards they will all produce the same results..

its all about settings and rsolutions.. it about bloody time folks realized this.. at high settings and resolutions its the grafix card.. at low settings and resolutions its the cpu.. and mostly only one bloody core of the cpu as well.. he he he..

trog

ps.. erocker dude.. power that cant be used aint any use to anybody.. so far none of this multi cpu and gpu stuff can be used by the average gamer to any realistic intent.. poor multi (anything) driver/software support is the gaming reality.. and muti gpus aint worth a wotsit in the benching world without a super fast cpu.. we are talking 6 gig to pull something out of more than two gpus if u aint got six gig.. the power of more than two gpus is wasted for benching.. another 200 mhz might be a new world record but so would another 50mhz from four cards instead of three.. not much use to anybody else thow.. he he he

the thread starter sees a gain with three cards in one game.. cod 4.. odd really cos it plays nicely enough for me with just one card.. and one cpu core if i want to labour the point.. :D

multi smulti zulti.. all because any fool knows two is better than one and four is better than two.. mind u dreamy eyed enthusiasts who cant wait for the next piece of hardware to spend their spare cash on aint exactly good judges of reality bless em.. he he

Sheesh, I better call Damulta again.. lol..

one thing I noticed with SLI is there are higher benefits with lower end cards.

When I had 2 8600GTs the scores were almost double, with the 8800GTs the scores went up about 30-40%.

Using 3 cards I would have gone 3850s. And using 4 I would use 3650s.

[RoachHotel]

I think that to be true when it comes to benchmarking MK. But in games I see a significant difference.
I am also a believer that my machine which may be identical to yours will perform and react differently to identical changes. What I mean is my machine in crossfire will score or act differently then yours in crossfire, even though the hardware and software is the same.

I also still think that from what I have seen in the charts, the only way to topple the charts is with CPU power. The video cards help some but without the CPU torque, forget it, your scores will suck. Which now makes be think, how many of these AMD guys talking about these crazy scores they're getting are telling the truth. I would like to see an AMD proc, and ATi card crossfire scores posted.
Challenge:
Can any of you with AMD chips, and ATi cards beat 14530? Show me..
p.s
This is a friendly challenge.. no stabs intented.. everyone here has had great points, and been of great help.

[MKmods]

thanks for the info. I am putting together a mutiple GPU comp (3 Nvidias or 3 or 4 ATIs) and this thread is gonna be very useful. Thanks

[cdawall]

you should do 3850s they are really cheap :D

[merkk]

hi

I have a 9850 running 2 his 3850 (256 ) with my 9850 at just 2.86
i have score a 14320 point score in 3dmark-06. I also have a amd 2x 5000 be and with it clock at 3.2 the 9850 has beaten all my fps score of the 5000 in 3dmark-06 .By the way 14320 is not the hightes for 9850 and using 3850 video cards 14750 is .The 9850 are putting a dagger into the heart of the old amd 2x 6400 cpu out at 3dmark-06 as i post this. The 9850 is now AMD new number 1 gaming cpu .

[Kei]

Hey Roach I'll be sure to post up and let you know what I get once I put a 2nd card in my box which shouldn't be too long from now. Once the scores get updated I'll be the highest AMD score (that I've seen on here) with a tick over 13,000 on a single card with only clocking up to 3Ghz (daily speed stock voltage).

I'm not sure if I can break 14,530 but I'll damn sure give it one helluva try! If I have the same or close to the same luck with the 2nd card then I should be able to at least come close to that score if not break it. My 3870 clocks very well though and it's not hardware modded at all. Check out the validation shot on the 3d06 results thread to see my total specs. I'm sure If I raise the voltage with a hardware mod I could score significantly higher than I'm score now and likewise if I had the desire to go up higher speed wise on the Phenom (set 3Ghz from day one and left it alone for now).

You just might peak my curiosity to see exactly how far this will all go.

Thanks,

It will be interesting to see if you beat it.. I hope you do really. I just want to see some actual numbers instead of the " I got 18k with one card, and no proof". Also it will tell me if I might really have a problem somewhere. I will jack up my vid cards and proc and try and beat my old score.. I will let ya know also.. Goodluck, I hope you beat it.

[RoachHotel]

Ahh I just noticed youre running a 9850 too.. You gotta good shot at my score.. go for it..

[spearman914]

I will tell you this now that I don't believe in 3dmark06. Its just **** with loaded ****. You really need to play a game to see some real difference. Try with one then two then three. Also I am sastisfied that no one mentioned it was the power supply. 3 cards is not good for 750 watts and each 3870 takes up 26 amps but ur psu only has 50. 26 x 3 = 78 :D

I will tell you this now that I don't believe in 3dmark06. Its just **** with loaded ****. You really need to play a game to see some real difference. Try with one then two then three. Also I am sastisfied that no one mentioned it was the power supply. 3 cards is not good for 750 watts and each 3870 takes up 26 amps but ur psu only has 50. 26 x 3 = 78 :D

no the cards don't use 26A each not even close to that

"3 cards is not good for 750 watts and each 3870 takes up 26 amps"

way way wrong.. each card will use 10 amps max.. 10 x 3 = 30 amps..

Hi what your canyon flight score in 3dmark-06 ? that the only thing that realy maters that show your crossfire score i look up the top score of a 9850 at 3.1 gzh. using 3870 and the dude nocking down a 96 fps in canyon flight test so if you are getting 96 fps or more changing over to a 9850 not going to get you much.

Canyon flight I just looked was 111.36 fps on my best score of 14620.

scaling from 2 to 3-4 cards sucks all round at the moment anyway, unless you game at 1920x1200 + 4xAA or higher. and even then depending on games gains can be minimal. for now at least this trend seems to go for ATi and Nv

oh and the benchies really love a 3+ ghz quad core if your after a speed boost. i have a Q6600 @ 3.4, and i put in a stock 9800GTX to see 14900 06 marks. so at that point 2 3870's CF on an intel board with a Q6600 @ 3+ghz you'd be looking at better scores than your getting now easy.

having a quad amd/intel cpu dosnt help the multi gpu scaling.. u get the same extra two core cpu score from the cpu tests with one gpu or four gpus.. the amount of grafix cards wont affect the cpu score at all..

its a one off cpu score gain from more cores.. nothing to do with C/F scaling.. actual core speed increases will affect the gpu scaling thow and increase the one off cpu score..

dude can you please post what fps you were getting in canyon flight with just 2 video card so we can see what kind of pick up you got going from a 2 card crossfire to 3 card crossfire . Iam looking at adding a third 3850 to my rig also (my 3850 need all the help they can get ) iam using a DFI landparty dk 790fx board so to do just need to get the video card

[trog100]

"my 3850 need all the help they can get"

i would have thought a couple of 3850 cards would cope with most things easily.. they should do if things are working right..

or is it just 2006 scores that need the help.. ??

Na the truth is i been very happy with how my ati 3850s and crossfire has been working other than some drivers troubles it been
all good for me just want to bump the crossfire frame rate up a bit more for better game play.I realy like the way my all AMD rig has came out.
