3.20 on q6600 on xfx 680i LT sli - Page 18

post #171 of 313
Tell us more about the voltage settings you tried and the multi, fsb speed memory settings/divider you've tried etc. or have you only tried default? And with your mobo, is default actually default?
On my mobo, when I overclock, voltage settings go up automatically when the settings are default.
Only with that info can we possibly help you.

From my priliminary testng I can hit 3.2Ghz with some of your suggestions but can't go to much higher. Currently I am at 3.246Ghz (or something) with all voltages at default and an 8x multiplier and it is solid. Prime95 and games are running great and 3DMark06 in Vista64 has given me and increase of 700 points over the last time.

No matter what I try to go above 3.246Ghz though it seems to blue screen on windows boot and then reboot the computer. Is this because of the 'vdroop hole'?

Thanks again guys.

well done on 3.2 mate.

as for the 'hole', its actually not anything to do with the Vdroop, although that would definitely contribute.

http://www.xtremesystems.org/forums/...d.php?t=154897

That link is a link to an image on how to apply the pencil mod to remove Vdroop. you need a 2B pencil (must be this kind of pencil), and you simply apply the pencil in between where the two red X's indicate on the image. All 680i boards are the same, i have done this personally and can vouch for it 100%. i wouldnt worry about the rest of the image, as those mods require some kind of soldering, which i have no experience in and therefore have never tested. Also, don't apply it while the board is on i dunno if you can or not, but i wouldnt.

**BEWARE: Applying the pencil mod WILL void your board warranty. It's very easy to remove, just use a bit of rubbing alcohol.**

anways, the 'Hole' you are referring to is actually a FSB hole, a major fault of this board. basically what that means, from my own testing, any FSB speeds from around 380mhz to 420mhz will prove severely unstable at almost any given voltage setting, regardless of multiplier. this range can vary, some might not cop as big a hole, some may cop worse. I think the official report was 375mhz to 421mhz or something. your best bet is to just test.

if you're willing to play with voltages, you really need to apply the pencil mod linked above, otherwise Vdroop causes massive instability. Vdroop actually isnt a bad thing, in terms of the board operating, but its bad for overclocking, as it fluctuates under load, which is why your system crashes.

I was using rob487's settings from page 6 of this thread and my machine ran solid as a rock at 3240MHz for three hours on a large FFT torture test with Prime 95 and the temps rarely got over 60 degree's.

So I dropped everything back to default, the multiplier to 8 and QDR to 1600 and DDR to 800 to maintain a 1:1 ratio. You are right that the voltages did change alright and I'll have to post what they are when I get home from work tonight. I did notice that the core voltage was in the 1.40 range but Core Temp reports the vid as 1.32. Thats a hell of a vdroop if I'm reading that correctly.

I went to QDR 1620 and DDR 810 and it worked fine. Then QDR 1640 and DDR 820 and it wouldn't boot windows. Finally tried QDR 1630 and DDR 815 and it worked fine at 3.26Ghz. Ran 3DMark06 before bed and it posted a score of 15,800 (which is the highest I've ever had in Vista64). And all the time the temps on load were barely creeping over 60 degree's.

Cheers for that mate. I'll have a look into this. Not sure if I should just be happy with 3.26Ghz for now though.

My lapped Q6600 G0 is now running at 3.3Ghz and it's now giving me the following results:

3D Mark 2001 SE = 60839
3D Mark 2003 = 60505
3D Mark 05 = 21442
3D Mark 06 = 17194
PC Mark 05 = 9773

I followed your advice with the pencil mod recommendation and it worked sweet as a nut mate. Idle voltage is 1.400 and load is 1.392 and temps are 42 -> 46 idle and 59 -> 63 (occasionally hitting as high as 67) under load. All voltages in the bios are left as default and report back as 1.40, 1.4, 1.850, 1.40, 1.50 & 1.2. Prime95 seems stable to me as well and everything couldn't be better.

One thing I did notice though was switching to an 8x multiplier was the key. as I hit 3.285 with a 9X multi but the voltage was 1.44 and driving temps up plus it also failed in Prime95.

Hopefully all will be well with it now for the forseeable future and thanks again for your help guys.

(PS, one final thing. Where the heck is the option in the bios to tell it to skip the Floppy Disk check?)

Well, I tested the thing myself at the shop last week. And I got it on 6*400 without much problems (just to check if it did 400). And I've seen a review getting it up to 425 (but not any higher).

Somehow I hope that it will do 8*400 or even 9*400 if I feel like it but I think I'll be running it at 7*400 the most times seeing I won't play Crysis (just benching it once or twice for the hell of it).

I'll be sure to check back in when I get the thing next week. But I don't think I'll be OC'ing it untill I actually need it.

(I just pumped the voltages slightly, set the multiplier at 6 and the FSB at 1600 right at the first POST, worked great. Too bad I don't remember the voltages, but they probably won't work with 8multi anyhow.)

I'm currently running 7*400 and I've had it running 9*333. My guess is that 8*400 will do fine and 9*400 will do fine as well. I'll try that later for you guys. I have also tried a 450FSB, it ran shut before even posting I think that upping the voltages a bit would be a requirement for that.



(2.8Ghz... Lowest Q6600 overclock willingly? I think I'll run it at stock next time I boot up anyways.)

Ok, tried 8*400 which did fine. I'll try 9*400 later, I'm having videocard driver problem I have to take care of first. 169.25 drivers aren't doing well for games as Crysis and CoD4. Crysis just runs shut after 15 minutes of good gaming (well... I wasn't really gaming, I was benching it and playing it at the same time). I've seen it's a more common problem with this driver and the 8800GTS G92. So I'll change it either tonight or tomorrow (I think).

I did however get a nice 3DMark06 benchmark, I get 11.530 on stock clocks and 14.8xx on 3.2Ghz OC and a Videocard overclock I don't remember the numbers of anymore. I'll redo it later.

I now get a bit of a lower 3DMark06 with the 175.16 drivers, though I think I'll keep them for now because the whole systems seems to run a bit smoother and so far I've played Crysis for like 20 minutes. Which was longer then before.

I'll go and try to run the CPU at 3.6Ghz for you guys now, and then I'll OC the card and run another 3DMark06.

EDIT: I tried 9*400 but it didn't run. I am currently doing 9*366.8 but I can go higher for sure. I just don't feel like upping the VID nor VTT. Also, this driver sucks for Overclocking... I could to 790/1975/1050 easily on the last driver and this one just stops 3DMark06 dead in it's tracks when at 750/1875/1036 near the end of the second clip with some error.

I'll try another driver tomorrow. I got a 13.651 3DMark06 with the 3.3Ghz OC and the stock 8800GTS G92 (on a 175.16 driver).

EDIT EDIT: New driver only makes me run Crysis longer then before. At stock clocks it still stops me after 30/40 minutes by just ramming the whole computer into halt so I have to press Reset to get it working again. I'll try other drivers later, this one won't let me overclock in 3Dmark06 nor will it let me play Crysis all that long...

EDIT EDIT EDIT: same driver as the last one in edit edit, it now runs fine. It needed a little time off before testing it. I probably screwed up the installation. It also runs fine on 750/1875/1000 with the CPU clocked on 3.365Ghz. I have everything set on auto btw, all voltages are on auto, the FSB/Memory are unlinked at 1495/800 and I have set the multiplier at 9 (also, I turned of C1E, goddamn what does that program **** up a lot).

I then proceeded to Flash the bios to the 680i SLI full version as per a post in this forum, it went painlessly, reason i done this was i needed the board to hit 4Ghz on a Q6600, which it done easily, the board does have massive Vdroop and unfortunately at 1.80v it only give 1.72v in bios, shame that as i could maybe have gone a lot further.

Still i just wanted to show some of the runs i done using this board and various GFX in SLi.

Test setup
HSPC Top Deck Station
XFX 680i LT (Flashed to Full 680i Bios)
Q6600 G0 SLACR
2x1GB OCZ FleX XLC PC9200

PoH Boy Water Cooling *D-Tech Fuzion*
2xAsus 8800GTS 640Mb Volt modded Cores @1.4v on stock coolers
OCZ PC Power & Cooling 750W Quad Silencer PSU

Mostly these runs were to push 3dMark06 on a quad for points

You might as well throw that CPU in the garbage. Why in the hell would you put so much voltage to that poor CPU? I could do that same exact overclock but I wouldn't be crazy enough to set my voltage anywhere near that high. I could already imagine the damage that has been done to it. The CPU may still be alive today, but it doesn't mean it'll last much longer even if you were to bump it back down to stock speeds. Poor little thing.
