e6600 on GA-965P-DS3 o/c ok, but won't reboot after o/c

[joep2k]

Hi

I'm having trouble o/cing my e6600 on my DS3 running F9 bios. It boots when I first start comp at 9x266, then switch to 8x400 using the settings:
mem +0.2V
mch +0.1V
CPU 1.39ish V
All the BIOS features are disabled

After I save and exit the computer reboots properly and runs everything properly, prime95, games etc.

From windows when I shutdown or reboot, it no longer boots, it was resets about 4 times, then hangs on the 5th or so time, and the screen remains blank. When I manually shut down (hold power button for 5 s) and start again, it goes back to 9x266, at which point I can get back to 8x400, etc.

I really don't want to be doin this everytime, and am wondering if there is a way of permanantly making it boot properly, or is there something wrong with any of my hardware?

Thanks in advance

Then it doesn't seem to like the overclock after all. Run Orthos Sp2004 small FFTs test overnight and find where it gives you errors. Check the temperatures with Intel Thermal Analysis Tool:

It sounds like it's resetting the BIOS back to default because it can't boot with those settings. Have you also added +0.1 to the FSB? Also try going straight for 401Mhz intead of 400 because that's easier for the motherboard to run at because it uses a different memory strap (from what I'm told).

Bump the vdimm to +.3v....vfsb to +.1v

It is actually a safety feature....it is doing its job so you dont have to pull the battery everytime...It will revert back to stock 266fsb times whatever multi you have suceesfully set (meaning it actually booted)....

Thanks guys, I think it was the +0.1V to FSB that got it working.

I'm still gonna try the Intel Thermal Analysis Tool and let you know.

I'll try lowering mem and cpu voltage though, cuz i think it was the FSB setting that was causing the problem.

I may even try 9*400 if the temps now are low enough. I do have a ultra-120 afterall.

One more thing, would you know which software fan controller would work?

 

[Roguestar]

Try speedfan for that sort of thing. Personally I just let all my fans blow at full speed; it's not too loud.

I just ran orthos overnight...
It only lasted 6hours and 26 minutes, is that good enough?

What could I do to make it more stable?

As for temps, I monitored it 15 minutes in the one core reached 64 while the other reached 62/63. Are those too high, should I reseat my heatsink (with fan pointing towards rear)?

I'm running an antec solo case with low rpm fan on the heatsink and exhaust.

 

[Roguestar]

I think you should reseat your HSF and reapply thermal paste just to make sure. Those are kinda high temperatures. Make sure the fan is blowing air out the back of the case through the exhaust fan.

Personally I think this is a BIOS issue. I have the same board with F7 BIOS, can run up to 3.6GHz without too much trouble 24hr dual orthos w/ looping 3d mark stable, but on some cold boots and restarts will do same as OP, note this does not happen every time and when it does i can simply reboot into the BIOS, change the settings to get to 3.6GHz and off we go to hours of gaming, work or whatever. This starts to happen at any overclock over 3.04GHz.

To me this seems to be another BIOS boot issue which has been around since F1 and gigabyte needs to fix.

 

[Roguestar]

Bizarro. Kind of glad I avoided all that and the D9 problems by cheaping out and going for an S3 .

@ joep2k: Running for 6 hours 26 minutes without error is good but if you mean that when you came back to it, it had failed at that point, I personally wouldn't be happy with it. I like my Orthos to run for 12 hours while I'm asleep and then at work (just got home today and it had run 14 hours 10 minutes and not errored yet) just to be as sure as possible.

 

[joep2k]

I just realized it had nothing to do with the voltages so far, I switched to F7 bios and now everything is fine at lower voltages. Also, I shouldn't have had to reseat at all, cuz the fan wasn't blowing towards the back the first time. Since then, I haven't been able to get as good a "seating", but ah well...gotta learn sometime

1.39Vcore is under voltage at 400Mhz. Try it from 1.425 - 1.4725V and ofcourse do stablize test.

Maybe your MB can handle that high of FSB? or MEM ? What's the FSB:MEM? If it's at 1:1 try to slow it down at 4:3.....Good Luck
