1.18 BIOS GPU Overclocking

With the new BIOS kicking the fans in at lower temps I have managed to push my 8600M GT a good deal further than I could previously.

Here's my results:

STOCK CLOCKS (475MHz Core/950MHz Shader/400MHz Memory)

3DMarks: 3738



OVERCLOCKED (655MHz Core/1310MHz Shader/490MHz Memory)

3DMarks: 4691



I want to know if anyones managed to push it even further I bet it can be done

 

What resolution did you test and which drivers did you use.

1. Stock, BIOS 116, drivers 174.70, WinXP SP2
Score: 3477 (1280x1024)

2. OC 675/1350/500, BIOS 116, drivers 174.70, WinXP SP2
Score: 4522 (1280x1024)

Not better than yours but with new BIOS, hmm... Isn't there also 119BIOS?

 

Not bad, but I did better long time ago.

Compal IFL90 T7500 @ 2.2ghz PQI 2x1Gb CL5 @ 5-4-3-14-15-4 XP pre SP3 32bit FW 171.23 8600GT 512Mb DDR2 (hynix 2.5ns) @ 690core/1630shader/504mem
3DMark 05 - 9358
3DMark 06 - 4697

Now I don't OC at all, since already two IFL90 of mine died, I'm not sure if it was cause of reasonable OC, but I don't want to take another chance.

By the way, how come you get such high score on default clock with slower CPU? Even in XP 32bit I usually got about 3450 pts. :/

P.S.It's still quite slow comparing to my main gaming RIG.

Yeah, that's what I think is odd as well. Much bigger difrence in between my results and yours is on stock clocks. My guess it's the drivers.

 

I used default settings in 3dmark 06 1280x800 and im using forceware 185.20 drivers

 

Aaah, the drivers make the diference, I'm sure. These are the best so far, except the DOX. Maybe.

 

1280x800 is not the default setting for 3dmark06, use external monitor.

 

Yes like I said, all settings in 3d mark are default with only the resolution differant. When my PC is delivered I will post results of 1280x1024. I'm still amazed at how high these clocks can go stable grbac has pushed it very far I'm about to test those clocks now

 

Here's My Latest:

3D Mark 06: 4953

With 693MHz Core Clock/500MHz Memory/1610MHz Shader

 

don't go any further... I'm already waiting a week now for my new gpu...

 

I managed to max out the core clock once to 715 with the shader clock linked and memory to 500 (The memory is the one that causes artifacts at around 500 so didnt want to push it any further) tested with furmark and got a max frame rate of 52. Scanned for artifacts using ATI Tool and had none for 10 mins before i used furmark. I checked to see that the clocks had actually been changed using everest and they had.

Weird thing was tho that i could only get to those speeds once with no artifacts... Now i just leave them at 630 1260 440

 

Hmmmm that is odd, are you using the new 1.18 BIOS? I couldnt reach my stable clocks for all games (660/1610/490) no artifacts or glitching/crashing I used to get prior to 1.18. I'm sure its because of the fans speed change. Also what drivers are you using? I recently switched to DOX's latest and they are fantastic.

 

1.16 at the moment might update it if i get the chance soon, or not on rereading your post. Using forceware 185.20 beta driver.

 

Sorry I mean when I had 1.16 (it came shipped with this version) I could not hold those clocks stable at all, it crashed mose games and stopped responding all the time, when I got 1.18 the fans kick in higher speeds at much lower temps and I can hold 660/1610/490 great with lower temps and no glitches.

 

What about the 119BIOS, has anyone tried that?

 

Ah k might try the 1.18 bios then sounds better at the moment at idle my gpu is at 72 cpu at 53... Quite high i suspect. Whats normal for this model?

 

normal idle temps must be in the 50-60 range for the GPU, and 45 - 55 for the CPU, at about 20-25 ambient temp.

 

Just updated to 119BIOS, did another benchmark.

1. Stock, BIOS 119, drivers 185.20, WinXP SP2
Score: 3555 (1280x1024)

2. OC 675/1350/500, BIOS 119, drivers 185.20, WinXP SP2
Score: 4627 (1280x1024)

3. Stock, BIOS 119, drivers 180.84DOX , WinXP SP2
Score: 3557 (1280x1024)

Didn't OC with DOX drivers yet.

 

I just installed Windows 7 and run a benchmark

1. Stock, BIOS 119, drivers 185.20, Win7
Score: 3398 (1280x1024)

I didn't try overclocking.

 

Argh, went back to XP. Couldn't get the bluetooth to work and I needed it badly coz I'm using BT mouse. And the lower score...
And did another benchmark...

OC 700/1400/500, BIOS 119, drivers 185.20, WinXP SP2
Score: 4682 (1280x1024)

BTW. I couln't get the shader clocks more than 1400, how to OC it to 1610 like dark_uk did?

 

Nobody talks about stable, it's all about -20 C degrees outside and millions of fans cooling it from bottom and only one pass of the 3dmark, no matter the cost. That's what OC is all about.
