OC Help, Ep45-DS3R, E8400

post #1 of 9
Thread Starter 
So, I'm pretty much totally new to overclocking and computer parts, and had a friend help me choose parts. That being said, I tried following a couple tutorials on overclocking, and advice from said friend on how to do so, but I get into system instability right away.

At default settings, I have 333x9, 1.225V Vcore, and the following timings for my ram : 5-7-7-24 @ 1.8v. I've tried gradually getting the FSB speed up, but as soon as I hit 350 Mhz, the system doesn't always boot to windows, and freezes at the start of any stabilty test, such as OCCT. I've tried boosting up the Vcore slowly up to 1.3v, and changed my timings to 5-5-5-15@2.1v, and still have the same problems.

I'd love some advice, but please keep in mind anything my experience other then the past few days of testing is pretty much zero.

Thanks in advance.

If you require any other information, please ask.

For 3.6 try:
vcore 1.275 (may have to go up-or can go down depending on your chip)
Fsb 400
ram 1:1 (or whatever you board says, mine is 2.0)
ram voltage to specification

I tried putting the FSB at 400, and tried Vcore 1.275v. I left the SPD Memory on auto, and it seems my ratio is 5:8. At default settings, CpuZ also gives me DRAM:FSB ratio of 5:8. Now, with those settings, my computer fails to post twice, and then reverts to the original settings. I tried upping the VCore up to 1.3, with the same results.

5:8 is running on a divider, you need to manually set your ram and fsb to a 1:1 ratio, which is 2.0 on a lot of boards. My E8400 runs on my board at default volts, 1.225, overclocked to 3.6GHz. I would try changing your divider first and see if that fixes your problem.

Indeed, I set it at 2.0, and 400FSB with 1.275Vcore seems to work fine for now, I'll do some stability tests, but the main problems seems to be gone. I'll do the gradual boosting of FSB/Voltage now and see where I can get on my own.

Thanks a lot for the responses Kpo and Bionic.

Cheers,

Question for you, since you have the same mobo:
What's your cpuz voltage show? You have no vdrop on your board?
My bios default voltage is 1.225 also but in cpuz it shows 1.15
I need to set 1.262 in MIT to get 1.236 in bios and 1.216 in cpuz

Good for you, keep your eye on your voltage and temps.

To answer you back, yes, I have the voltage drop in both CpuZ and Everest, but not in the OCCT monitor, or at least a lot smaller.

OCCT will show a .02 drop on load in mine.
