P35-DS3R and E4300 Stuck Overclocking

[jwolf24601]

I have a P35-DS3R v1, E4300, OCZ Gold pc6400 in 2x1gb and 2x512mb

Power supply is PC Power & Cooling 610 silencer

I got the FSB up to 300mhz no problem

I set the Memory multiplier to 2.0 and lowered the timings, so it's running at 600mhz and 4-4-4-12

I locked all the voltages at standard, set PCI-E to 100mhz and PCI to 33mhz

Speedfan is saying all my temperatures are very good.

Been running like that for weeks now.

Playing EQ2 though I have been yearning for more processor speed, since it is a very CPU intensive single core only game.

I tried bumping the FSB to 310 and it worked for a few hours and I got BSOD.

After that it would not boot at 310fsb it would restart and settings would be default.

I tried raising the voltage on the cpu to 1.35 and 1.4, I even tried letting gigabyte designate the voltage automatically.

I relaxed the memory timings and it still does it.

I should be able to get past 300mhz with it shouldn't I? I mean the load temps are only in the mid-high 40's

Any ideas what I might be doing wrong?

Do the ram sticks have the exact specs: timings & voltage?

You would raise mch

ddr2 = specs (normal = 1.8v)
pci-e = normal
fsb = normal or +0.1v
mch = +0.1v - +0.3v
vcore = you specify

You could try 400 x 8. Yep, the chip should go pass 3ghz hands down. What's the cpu cooler?

I would try OCing it with just the 1GB sticks of ram in and see if you can get your FSB higher. You may be having problems with getting your memory setup properly using unmatching sticks.

Zalman 7700cu is the cooler with Artic Silver, got pretty good temps I think. @2.7 29/29 idle 49/47 load

I fiddled with it more last night and was able to get it to run well using the auto voltage thing gigabyte has.

333x9 Was prime stable 8 hours.

I had to reset the memory timings. I thought i could get them to work at 667mhz with 4-4-4-12 timings, even with the voltage set at 2.1v(1.8+0.3) it would not do that. So i set the memory back to 5-5-5-12 and set the multiplier at 2.4 (4:5) and it's running well at 800mhz, though still only if i let the board manage the voltage.

Since I don't trust the boards automatic voltage, I'm going to try what you suggested.

The 2x1gb set of OCZ Gold ram is 5-5-5-12 800mhz @ 2.1v
The 2x512mb set of OCZ Gold ram is 5-5-5-12 800mhz @2.0v

I will try runing the voltage at 2.0 if that doesnt work 2.1, slight undervolt or slight overvolt on either set should not bother them.
