ASrock 890GX Extreme3

[biohead]

Heres the thing, I have vcore set at 1.4 *which oddly enough is their default* I don't have this problem at all now, its when I try to run anything lower.

If it were a heat issue, it would be happening at the higher voltage and not vice versa.

There are a lot of things I wish I could change with the board, mainly the bios, and the finicky "ASRock OC Tuner" but hey.

aha, i'm in the same boat. i never had CnQ kick in until i was running 1.35v 3500mhz. Disabling Cool n Quiet in bios does nothing.

running a 8+ hour prime blend stable 258*14 now (3600 mhz), 1.3625 vcore, but i have to force the p-state table with K10stat so it doesn't jump up and down all the time. at 3500 mhz CnQ wasn't an issue (so it didn't matter in windows/idling) but at 3600 it causes stability problems (clock interrupt BSODs), i guess when the frequency jumps up faster than the vcore that goes with it, and causes instability for a fraction of a millisecond.

this 880G needs some work now that i've gone to know it. unbootable HTT@ 290-300, high vcore jumps under load causing load stability but idling the vcore is too low and the system locks up (imagine that :/ ). CnQ issues as noted. also i tried the gimmicky "instant boot" utlity but i don't think the board is supported yet, it doesn't instant boot anything. the OC tuner is unstable clocking the HTT bus and applying multies doesn't work (K10stat does work for multies/vcore). also, AMD overdrive doesnt load and hardlocks the system, same goes for AMD fusion utility.

list goes on. hopefully it all comes down to a BIOS update.
