Thanks for the information I will try to use this as a starting point and see what happens

What I have tried
CPU frequency 233
CPU/NB 1.2 volts
CPU 1.435 volts
Turbo Off
CPU Load Line Calibration- It tells me in my bios that if set to overclocking mode or manual to disable this
NB multiplier Set 2 steps down
HT bus set to auto because I don't know the stock value
CPU multipler set to 4.6 ghz
My temp reading are perfect just my tweeking is off. I can run Prime for about 5 mins and half the cores will fail. This a fun game of cat and mouse and I know im getting closer because the second I would run prime before it would freeze my computer.
With these current settings what should I try to get this stable?

The HT link on auto sets it to 2600mhz. In order to test stability for the cpu to find your highest clock or where you want to be, start out with the ram a step or two under rated specs. cpu/nb and ht link around 2000 or as close to it as possible. (you can mess with these settings later once you find your stable oc)

cpu/nb at 1.2v for a 233 fsb may be a bit low. I would up it to at least 1.25v and try that first with the same settings you have. You may also need to bump cpu voltage another notch or two. Have you tried every cpu voltage notch below 1.435?

Right now on my 6100 i am stable at 4.730ghz at 1.425v but i have 2 cores disabled. Before with all 6 cores it took almost up to 1.5v

8150's run hot and if you dont have a good chip it will require alot more voltage than you think to reach the potential you want out of it.

I would also try taking 2 dimms out and only use 8gb of your kit. Trust me, i had to do it or I could not find stability with a higher OC.

@ kalistoval: Your temps r to high, considering u have NH-D14 even if u have bad airflow ! Try to test it without side panel.

this maxmem test was garbage and thats becouse of 1 thing in the bios that needs to be changed and here is the problem
now i corrected that problem and ran prime95 at the same exact setting with only that changed to 110ns and did a 15 min stability test
and heres the maxmem score its a silghtly better score with the same stability
heres my 4.5ghz




this cinabench was an unstable oc of 4.6 ghz and 2600 cpu nb & 2600 htl @ 1866 9-9-9-24-1t 1.4375v vs a stable 4.5 ghz 2400 cpu nb 2400 htl with the same ram timing and voltage
now i just like to mention i have a pos psu that only cost 40 bucks atm its an inland 600w and also i have very very a poor cooling system i havnt put much effort in adding more fans i only have the 2 noctuas and i have a pos case with terrible air flow i no longer have my antec lol so dont let my temps discourge you also remeber prime jam packs data to your system i doubt any average person will do the high level computing that prime does to the cpu
im ganna try a 2600 nb

Your temps are way way too high. At 4.5 you're fully 20C beyond AMD's stated max safe operating temp (tcase max) of 61C. What is the ambient temp of the room your system is in??
With your setup, using an air cooler, you're going to get minimal gains moving CPU/NB beyond 2200 @ 1.2V meanwhile adding more voltage and creating higher temps for those minimal gains on top of the already high temps you're getting.

i was having a chat with a friend yesterday about that.... and he told that 1 bent (or ir can be worse as in "missing pin) pin, was causing that kind of temperatures... try to check everything again... temps WAY damn high

is phenom x6 4ghz hotter than fx-8xxx 4.5ghz ?
post #5658 of 8112
Nope, not from my experience. The FX 8120/8150 is definitely hotter at 4.5Ghz over the x6 at 4.0Ghz when using Prim95/ITB.

underwater at least. Snorkle.gif

But FX can whitstand much higher temperatures then Phenom and remain stable, so we can call it a draw smile.gif
