Overclocking 3870 x2 Guide
Fed up with pussy clocks in CCC! FVck it! here's what you do. FYI you do not need 6 pin and 8 pin psu dongles connected. Just two 6 pins dongles are fine.
1. If you want to run fan at 100% download and install riva tuner 2.06 and do the following: x:\Program Files\Rivatuner 2.06\rivatuner.cfg Comparing files rivatuner_2.06.cfg and RIVATUNER_2.06_8800GTS_G92_3870X2_RV670.CFG ***** rivatuner_2.06.cfg G86 = 420h-42Fh G92 = 610h-61Fh ***** RIVATUNER_2.06_8800GTS_G92_3870X2_RV670.CFG G86 = 420h-42Fh G92 = 600h-60Fh,610h-61Fh ***** ***** rivatuner_2.06.cfg RV630 = 9588h-9589h RV670 = 9500h-9501h,9505h,9507h ***** RIVATUNER_2.06_8800GTS_G92_3870X2_RV670.CFG RV630 = 9588h-9589h RV670 = 9500h-9501h,9505h,9507h,950Fh ***** edit your rivatuner.cfg so it looks like the bottom entry, the important line is the rv670 one for you. Open notepad as Run as Administrator, open the rivatuner.cfg in x:\Program Files\Rivatuner 2.06, edit the RV670 line so it looks like this: RV670 = 9500h-9501h,9505h,9507h,950Fh save it close and restart riva tuner 2. Download amd gpu clock tool here: http://www.nordichardware.com/skrive...kTool_v0.7.zip You will need to apply this patch to the root in AMD gpu tool before running the program. here: http://www.nordichardware.com/skrive...16/ToolLib.zip 2. run AMD GPU clocktool, see on device - BN:3, DN:0 = GPU1 and BN:4, DN:0 = GPU2... BN:3, DN:0 = GPU1 BN:3, DN:0 = GPU1 will show default clocks(825/900) 3. select Bn4 core and type in your gpu and mem clocks and hit apply. then select the second Bn3 and do the same. Check your clocks by opening the thermal sensor tab and hit start. it will show current clocks for both gpu's and mem 4. next try to max out each core and mem by overclocking one slighty higher than the other core and running a benchmark like 3dmark 2006. if it fails then you will know which each core maxes out so you can get the optimal performance from the card. Do the same for the memory.

I recommend modifiing the cooling, if nothing else, just apply some AS5 to the cores and check if the backplate does have contact w/ the rams as mine didn't.
BTW: it DOES work for Vista x64 ![]()

I'm getting close to 19k in vista with e8400 @ 4.3 ghz c2d 4 gigs of ddr3 @977 mhz
3870x2 is clocked at 932mhz/1026 mem gpu1 932/1026 gpu2 fan at 100% default bios. pcie frequency at 120mhz I was getting mid 16k at stock clocks. I'm sure if I benched in xp it would be about 20k

I've got ~19800... can't get thru 20k mark
tho.The card behaves strangely, the higher the clocks, tme more fluctuation in results.. With stock clocks it's fine, giving me almost the same results, but when overclocked, it seems to have a problem maybe it has something to do with the internal CF link chip, or maybe it's because of the ODD cooling solution (Why did they not use the same material on both cores??? ) or maybe the GPU clock tool only changes the frequency of one RV670, or maybe it's something completely different ![]() nonetheless i'm lookin' FW to the new atitool/rivatuner. as i'd rather forget about the gpuclocktool completely ![]() Update: It's a problem of the Vista driver or Vista itself... in XP, things look different: have a look below

no, its 32bit...
But I might try a little later... Need to reinstall this sh*t anyway, I might dump it completely. It's annoying, slowing things down and is no better in any means then XP... Except for Dx10 ![]() Thanx BTW ![]()

860/1050? both cores?
I'm lucky then. 958/1145 gpu0 945/1145 gpu1 took the top spot in on the orb for vista and c2d and 3870 x2

Lucky
![]() What cooling do you use? Mine's stock, except for the tim as it was replaced for AS5. I don't want to go any further, as this card goes back to the wholesaler since the've sent me something else than I've ordered. I'm waiting for the other ASUS card, as it's supposed to have .8ns samsung chips on. 2.5GHz DDR3?! ![]() I hope they didn't lie! Then some water.... we'll see.

...be careful with srewing things down as hard as you can, as most stok coolers are "shit engineering"... Other than that you may break your card when overtightening the screws! Just scew as much as necessary, and not beyond! I've seen cards looking like a rollercoaster
![]() 950 w/ stock cooling is sweet, anyway ![]() Edit: BTW, be careful with condensation, even in the window... Especially in the window ![]()
