AMD Indexed Overclock Speeds

Andy_007 said:
Okay this is going to take a bit of explaining, well actually read this (http://www.ocztechnologyforum.com/forum/showthread.php?t=25339) just ask if you dont understand it. Its great ram, im so glad i brought it, i was running crap ram b4 that would only overclock to 880mhz. Im runing a pretty old Gigabyte GA-M57SLI-S4, its a good motherboard abit temperamental sometimes but it overclocks well.

Wow! Andy,

Thanks for some good info!!! I've learned something there!!
But tell me... so then if i understand correctly, it means that my ram is running on..

240 * 12.5 = 3000Mhz so 12.5/2 = 6 so 3000/6 = 500 so my ram is running on 1000Mhz..?
can that be?

Ohh! i have to multiply with 1.5!! okay so its 500*1.5 = 750! Ja thats correct!!!!

Thanks Andy!!!

Your most welcome :toast:. Yeap that looks to be the right maths, If you have 800 ram speed set in the bios it would run at 1000mhz, but use CPUZ to check use the memory tab up the top. Since 12.5/2 is 6.25 it might be running at 3000/7 but it shouldnt.

I dont think you quite get how to work it out, dont worry it took me hours to figure it out.

If 800 is set Bios divide multi by 2, for 667 divide by 1.5 for 533 divide by 1.33 for 400 divide by 1, then round the answer. Then divide CPU speed by the answer you just got.
So For example if your running 3ghz @12.5x

800=12.5/2 =6.25 3000/6=500
667=12.5/1.5 =8.33 3000/8=375
533=12.5/1.33=9.4 3000/9=333
400=12.5/1 =13 3000/13=230

Yes, but then I'm right?? Coz i said 750.. 375*2=750.. What u think?
Hey Andy, I cant get anything more than 3.1Ghz out of this cpu..
I'm on 1.41V stable Max Temp was 59 on full load.. Anything more than 3.1Ghz
then no post..

What do u think?:confused:

AMD only uses exact dividers for ram so

DDR800=2500mhz/7x=714mhz
DDR667=2500mhz/8x=625mhz
DDR533=2500mhz/10x=500mhz
DDR400=2500mhz/13x=384mhz

Yes you times the result by 2 to get the actual ram speed, but i thought you we getting a bit confused a few posts back. I would say it needs more voltage but those temps are a bit high, just try with extra voltage to get it to boot but i dont think i would like seeing it running at over 60 full load. Did you find out the model of your heatsink, it would be a great help to see if its just the sensors out of wack.

I did know that use exact dividers but i forgot about always rounding it up, thanks for that.
 
I just did my virgin OC on my new system. 100mhz and see how she runs. :D

Finally! I got the thread revamped and up to date! I deserve a thanks for that.

Updated with Average speeds for all categories. Windsor is leading the pack with 3.19, aside from Kuma, but I only have one sample. If you have any suggestions, please post them as well as scores.

looks good so far. i will toss a manila clock up shortly
 
I am planning on putting voltage and HT speeds in the tables as well. Since it's a lenghty project, I want to know if yall would like to see it happen. It would look like this:

[table=head]Brisbane|Clock Speed|Voltage|HT
Post 2|3.1GHZ|1.575V|3X
[/table]
 
maybe just cpu type/clockspeed/volts

HT link IMO isn't as big a deal


so

5000+ BE/3580mhz/1.678v

Well, the HT link isn't all that hard to add and it would complete the OC settings out. Or do you think that I am just wasting my time since I have all the post numbers clickable from the front page?

might be a bit of a waste since you were nice enough to make it clickable

Updated and I have the Brisbanes listed with the volts on the front page. HT didn't look right and most people didn't post it. Do you like it with the volts, or without? With my index, it's actually pretty easy to set the volts.

looks very good with volts maybe red out insane voltages yellow pushing it voltages and green safe voltages?

I will look into that possibility a little later on tonight. Right now, I have a timing belt to install lol. If you think of anything else to add, just PM me, or post a visitor message and I will look at it. Also, you Phenom II boys, start posting some clocks in here!!!
 
* X2 6400+ BE Windsor
* 3411MHZ
* HT Link 1065mhz
* Multiplier 16
* FSB 213
* CPU Voltage 1.47
* Zalman cnps9700 NT
--idle: 30C
--load: 40C
* Patriot Viper DDR2-1066 2.1v
* MSI K9A2 Platinum 790FX

i'm going to try a different overclock soon, aiming for same voltage but higher bus.
 
Here's mine the settings are in cpu-z screen but i'll list them as i have them set
