As you can see, it seems to be failing at pretty low increases, not exactly sure why?
This is the error I'm seeing in Prime95:
"ERROR: ILLEGAL SUMOUT
Possible hardware failure, consult readme.txt file, restarting test."
I've not touched my NB Multiplier as I don't really know much about this. Although what I have read it's more of a tweaker once you've found a stable overclock...... Not sure how right I am there mind...
So right now, I've got a "35 minute" Prime95 run at 4.1Ghz. I find it hard to believe I can't go higher than that... I could start increasing my voltages but I'm not too sure how high I can go without causing damage? I'm basing my questions around this review:
did you shut off all all the power saving options etc . i know when i didnt i got similar results.
my 8320 is turbo disabled, all power saving options off, vcore 1.38, mult 19x so thats almost 4.4ghz but can easily go past that fsb @ 230 , nb 2200, HT 2200 . i would set your dram settings manually so set the frequency and check the ram timings. i know my timings would go crazy on auto but set manually it runs ultra smooth now.
the power saving featured are most likely your problem. cpu and pcie spread spectrum should be off as well as cool and quiet and c1e etc should all be off
also you just running a single stick of 16gb or 4x4 etc. since running more stuck + more voltage needed on the nb
i would do all of it since your most likely going to have to adjust them later on anyways. with 4x4 im not sure how much of a voltage boost you may need so leave the nb voltage etc on auto for now and see what it it is running it at. but when you change the ram frequency try to keep it at 1600 for stability reasons as well as find out your timing for each sticks. if im correct its 9-9-9-24 for the 1600 mine is 1866 9-10-9-27. i would highly recommend putting manual timings in for stability reasons since auto will sometimes throw these out of wack
Then a bit further down it has under "Voltage Config" - "CPU Load-Line Calibration" with another load of Voltage adjustments, which are all set to Auto at the moment. You should be able to see it in the screenshots.
i have this board and an fx8350 and i was having problems when i tried to over clock the cpu with the north bridge over heating so to solve it i took the cpu fan from an old 3500+ took the fan off the heat sink and zip tide the fan right above the north bridge now i can run at 4.3 ghz with my antec 620 water cooler and it no long down clocks its self do to heat
