The Official Opteron 939 Overclocking Thread

[Absolute_0]

Dude, what is limiting me?? I have a cab2e 0540 FPMW. I had it stable 2.87gHz w/ 1.39 volts load temp 39*C(air) for 9 hours 10minutes on prime95(i stopped it myself).


Things that I have not touched since, are:
LDT: 1.30volts
chipset: 1.60volts
LDT/FSB freq. ratio: X 4.0
Dram: 2.8 volts
.....

Dram isn't really the limiting factor I would imagine...

But I can't get this stable above 2.90Ghz(10X multipliers). The highest I cranked the volts in the bios was 1.50volts, putting it at 2.93gHz, and it will fail prime after 20minutes or less even.

This is ridiculous because @ 2.87gHz, I was running stable w/1.39 on smartguardian and 1.425volts in the bios... I guess I can't judge it by that, but still, am I not stable because I need to crank up even more voltages on my cpu vid control????

help please!

Change your HTT multiplier to 3x. Also, what are the load temps?

Change your HTT multiplier to 3x. Also, what are the load temps?

Load temps are 39*C for 2.9Ghz and below... although it did get up to 41*C when it was at 2.94Ghz. Generally, load temps are looking ok.

HTT multiplier to 3x?!?!!?!!? you mean from (I'm currently on)10X=> 3X?? Or did you mean the ldt/fsb ratio(I'm currently on 4X)?

I'm assuming the second one of course, but I'll wait for response.
