opty 146 cab2e o548 under phase need help

[pocketbikeuk]

it has a major cold bug and jusy wont boot into windows or run in windows with my ss on if i turn it off it boots into windows at 3300mhz fine no probs but then as soon as i turn my ss back on and the temps drop towards 0 it hangs up is there anyway of getting around this ive been told to install the acp multiprocessor driver anyone here tried this? im going to update the bios on my dfi nf4 ultra d try increasing the drive strength and lowering the ht to 2x ive tried core v up to 1.9 briefly is it safe to go to 2? and also if anyone has a opty that has no cold bug i have cash here waiting so please pm me or just post in here and il pm you about it. any info much appriciated

You're gonna kill the chip if you're messing with 2 volts and turning the single stage on and off. I have a CAB2E chip as well, the cold bug is terrible, i have ACPI multiprocessor installed but it just makes load temps slightly hotter. Basically these chips don't work on single stage.

the acpi multiprocessor driver forced my 148 to 100% load temps while idle. so it would be worth a shot. as for the high vcore

You should do the multiprocessor tweak and other than that you can run super pi 32m or prime test at the background to heat up the cpu rather than giving it 2 volts. You would burn it up quickly otherwise

I tried my cab2e 148 under phase too, couldnt boot at any speed. acpi multiprocessor might help a little bit if you are just benching but prob is not good enough for 24/7 op.

I dont think ACPI multiprocessor will help enough. Even with ACPI on, full loading, and 1.6 volts, my temps only got to 0C and i can't even clockgen to 3.0 Ghz before it locks up.

Bottom line: most of these CAB2Es need very positive temps. I think the SS is a waste of time on them. Someone in a different thread said his CAB2E bugged out at +14C core (started locking up prematurely). So these aren't good for much more than watercooling /crappy waterchilling.
