Gigabyte GA-P35-DS3L Thread

[Galeo Deus]

I have a problem that I've been researching on and off for the past year, and have yet to find a solution.

Specs:
Gigabyte GA-P35-DS3L
Intel e6750
4x 1GB OCZ Reaper PC2 6400 (DDR2 800)
OCZ 700 watt PSU

I CANNOT get my machine to POST with ANY kind of OC. Trying to get the machine to POST with any FSB number over 333 will not work whether it's 340 or 420. Every once in a while, if I volt the HELL out of everything (like the memory running at 2.4 and the CPU at 1.7) I can get it to POST. But a restart always kills it, and it reverts back to 333. It's that FSB that's the problem: I can downclock the multiplier to 6 and it will not post above 333, even with the FSB overvolt and north bridge maxed out.

I have tried: every BIOS since F7. Every BIOS configuration in every forum out there like this. 2 differnt PSUs. Every stick of RAM in different locations, from 1 to 4 in there. Probably more that I can't think of. It's a testament to the solidity of this board that I haven't fried it over a year of attempting this on and off.

My question is: What the hell is going on? Is it the CPU? (I'm trying to avoid buying a new one, so I'm OC'ing!) Is it the RAM? The only thing I haven't tested is different RAM, because I don't have any around. (Yes the RAM checks out. Rock solid at 4-4-4-15 at 800mhz [6:5 with FSB] or 667 [1:1 with FSB] in Memtest and prime95.)

To say the least I'm at a loss here. The only reason why I'm trying to get this going again is because I'm starting to play some PC games again.

What happens whenever I try to OC is it wont go to POST, just hangs and spins it's fan, or it reverts instantly to 333.

Post your bios settings.

Well, it's stock right now. The only things I've changed from standard settings is boot order for devices, overvolting my RAM because it runs at 2.1 stock, turning off my serial ports 'cause I don't use them, and turning off the splash screen so I can see the POST.

Everything else is auto and such. If I manually set the FSB to 333 it works fine, too.

Woah, checking your sig it looks like you're running one hell of an OC on the same board as me. With an F4 bios, no less, which appears to not exist on the Gigabyte page. Is this some kind of magic BIOS? I wonder if I flash to this if this would help, but I can't find it anywhere. I've now tried every BIOS from F6 on as of this afternoon, but nothing makes a difference.

BTW, what are your BIOS M.I.T settings, homestyle? I'm really curious how you got this OC at stock voltage.

Did you try the newest bios F9b?

Of course.

No change in anything.

I've got some final exams to finish before I can go back home and check my bios settings. I'm not sure what the deal with the F4 bios is, but it came stock like this 1 year ago. If you can't get stable with the other bios versions then you probably can't get stable with F4.

But on memory, I have ...

graphics booster... auto
multi .... 7x
fsb.... 472
pcie .... 100
cia2... disabled
spd.... 2.0
performance enhance.... turbo
5-5-5-15

voltage manual
ddr2 +0.2
fsb... normal
mch normal
cpu...1.4

I've had this machine for a year now and have never been able to fix this problem. Intermittently, during the boot process, it will hang at "detecting IDE drives." If I immediately reboot it, it will boot up just fine. From what I've read online, this is probably caused by the motherboard booting up too fast for the hard drive. Gigabyte addresses this issue in their motherboard FAQ, but the setting they refer to doesn't exist on this board. So, short of taking a gamble by replacing the hard drive with one that may or may not fire up quicker, am I just stuck with this problem?

i cant get the darn thing to stay at 3ghz, i have the multiplier at 9 with regular fsb so its at 2.4ghz. when i change the fsb to 333 and put the volts at 1.3 it restarts itself twice but then it puts it back down to 2.4 -_-

Do you have any usb components attached? If you do try unplugging them and try again.Or if you haven't already update your bios.
