Wolfdale e8400 3.0 won't OC passed 3.08ghz

post #1 of 8
Thread Starter 
My PC won't post at all if I take it to as little as 3.10 (345fsb x9.0). Any ideas?
I tried both manual and automatic voltages. PCI-E frequency is @ 105. Tried setting advance ram settings to 5-5-5-15. wth.gif I'm not giving up. I know there's a solution out there which is why any help right now would be appreciated. redface.gif

Motherboard: GA-G31M-ES2L
CPU: e8400 Core 2 Duo Wolfdale @ 3.08
Power: Thermaltake 430w
Video Card: nVidia Geforce 9800 GTX+
Ram:G.Skill 2x2gb DDR 2

I've tried 1.23-1.25 and 1.30 and nada. I've raised the voltages for the ram and other stuff by .1

Sounds like 45nm can go a little higher. See what 1.36v gets you. You might need to bump the NB up to keep things happy. Leave the ram alone.

First thing to check is disable spread spectum in your BIOS so your FSB can clock higher. Second of all, run your ram 1:1 with the FSB so if your default is 333mhz, your RAM will be at 666mhz. The motherboard you have is a G31 chipset and generally does not scale well with FSB overclock. Your max will be somewhere around 400mhz FSB range. Let say you disabled spread spectum and did 1:1 with RAM and you still having trouble with booting pass 345mhz FSB, then I would either increase the NB voltage (if there is any) or decrease the multiplier from 9x to 8x and FSB pass 345mhz. If your CPU runs fine at 333x9 = 3ghz and will not run 345x8 = 2.76ghz, then it is very likely your motherboard does not like high FSB. Other possibility could be your RAM is holding you back. If you dropped your latency to 5-5-5-15 and push the dram voltage to about 2v+, then I don't see any issues of DDR2 667 RAM can't run at DDR2 700 speed...

OP, update your sig rig. I'd like to know what cooling you're playing with.

I had the same motherboard with the same CPU in another PC (my sibling has it now, albeit it runs at stock), only it had 2GB OCZ Gold 667MHz RAM, and I was able to get the CPU to boot to 3.6GHz (9 x 400MHz). I didn't stress test it though, but I at least was able to easily boot with it. I think I gave the everything +0.1V or whatever.

bump the NB voltage to its max, and make sure it gets air. Keep your RAM 1:1, hopefully it's at least DDR2 800.

G31 is a crappy overclocker, and is going to top out at around 410-420 FSB. Even if you can get 420 stable at 9x, you'll have to hope your power phases don't burn up.
