AMD 965 - Stability Help Please

[teh187]

AMD 965 c3 at 3.8ghz

1.412v - cpu voltage (may be a few 0.005/10's under or over)
1.3b - cpu nb
corsair low profile veng 1600 down to 1333mhz 8-8-8-24-2T (read amd likes tighter timings)
nb speed 2400/2000 ive been switching in between for linx testing

Just installed a noctua cooler today from a basic arctic cooler and temps are now better, but temps are not my issue at the moment, its the stability.

I've passed linx a few times with the settings above however now and again a test will fail, why is this? Hope i can get some help with this, thanks. Also now and again i may get some crashes, earlier on today i got a bsod memory management error. Maybe its my timings? ive already tried many but not sure which to stick at. Im still an oc noob so please reccomend me any settings i could change.

ok well say what your temps are but for the moment put your ram 9-10-9-27-2T which is stock @ 1600mhz bring your voltage to 1.45v and keep your NB 2400mhz bring your cpu to 4ghz test and once stable which you should be then drop your ram to 1333mhz at 8-9-8-24-2T which is a better setting as phenom II's can only utilize 1333mhz ram

Ok thanks well at linx full pass with the settings i stated above i hit 52-53 degrees max. Prime crashed overnight as usual (closes all together) and other applications on the computer crash also. Idle temps 32-34.

Edit: ok after trying your settings ive crashed 2 times once linx is opened 1 time screen freeze lock up the next was a whole bunch of colours mixed together and the system restarted... back on 3.8 now with my old settings which passes on linx but now and again system crashes so its kinda hard to tell when it will crash
