I got up to about 4.0 on my 965 with 1.5 ish volts

I did a memtest before I went to sleep, 15 passes and 0 errors with the same settings I crashed on, so Idk.

for OC the bsod 0x050 you are supposed to fix: "Ram Timings/Frequency or uncore multi unstable, increase ram voltage or adjust QPI/VTT, or lower uncore if your higher then 2x"

1. what is uncore multi? is that my multiplier? if so why not say that?
2. What is QPI/VTT? I googled them and I can't figure it out nor what those settings are on my PC. Is it? VDDNB and hyper transport? eh-smiley.gif
3. I don't know if my "uncore" is higher then 2x, because I don't know what it means by uncore and what the default is.

doh.gif

those descriptions are for the Intel crowd. Rough equivalents are uncore = CPU multi, QPI/VTT = CPUNB voltage.

what you want, is your Vcore about 1.5V, try upping your CPUNB volts to around 1.3V, and maybe nudge your RAM voltage if its in stock. Oh, and what speed is your RAM running at?

1) Max CPU voltage is 1.55v
2) Max temps is 62c
3) MAX CPU/NB voltage is 1.5v
4) Keep HT speed near stock speeds (2000)
Now read this.

ok I'll have to mess with the NB voltage again.

Right now I'm running 3.8 and I have to go to 1.5v cap to have that(1.488v) and have been testing my ram, its running at 1066 5-6-6-18 and 2.1v as it says on the stick and 0 crashes or problems. I even get some performance difference by 5-10fps.
As soon as I go to 3.9 I get 0x0124 unless I have my voltage cap up to 1.6v, and if I do that then I get 0x050 no matter my ram settings, auto, 400mhz to 1066mhz and just about every combo of timings I can think of.

either when I'm loading into bf3 I'll get when Im using 3.9:

or 20min ingame it'll happen.

ouch! 1.6v is a hefty volt. i just got 4.0Ghz with 1.52V tops, CPUNB at 1.31V i think. Are you running an AM2+ board? just with you using DDR2...it may be limiting you on the power front? I think AM2 boards have a slightly different VRM setup which can limit things.

I'm on an AM3 board, but when i was overclocking mine, i hit a wall at about 3.75Ghz....then it needed much more Vcore, (from about 1.4V up to 1.52V) and I had to lower my RAM speed - though to be fair i couldn't use multiplier overclocking - I was using the FSB (i've a locked chip, my FSB is at 267Mhz). Maybe try loosening your RAM timing, try a lower frequency for the ram, and get the cores rock solid on overclock, then work on your RAM speed. thats how i eventually got to 4Ghz I had to leave my RAM at 1424Mhz, it wasn't liking 1667Mhz + smile.gif

PS - can you try setting your RAM to 6-7-7-21? that'll loosen the timings a bit, and might help.

PPS - had a quick look at the Exception Code: c0000005, its trying to access a nonexistent memory address, either caused by a corrupt heap, or misaddressed memory.
= either your CPU cache or the memory controller are corrupting data (IE run out of overclocking steam). Up your CPUNB a little, and check out overvolting your DDR2 RAM, see if it helps. (Sorry, i don't know the safe limits for DDR2 voltage. Can anyone with DDR2 experience pitch in?) Either way, it a hardware exception that the processor is throwing, due to misaddressing memory.

That was just about same experience I had, switched to AM3 with DDR3 and 4.2 is no problem any more. I think that just DDR-DDR3 is the problem but controllers that can not surpass much what they are made for.

From my experience, 0x0124 is due to insufficient NB voltage, and 0x050 was a problem with the memory. I would say you need more NB volts as this can also cause a 0x050 error, or perhaps you have hit a wall. Can you up the NB voltage a notch instead of the CPU voltage?

Sorry haven't read through the entire thread and this may have been mentioned already...

Edit: read through some other bits of your post - u got a pic of the CPU and MEMORY tabs in CPU-Z with your current settings?
