Ok, testing with y-cruncher, it lasted 10 seconds before I got a BSOD!!!

I really think I have a DUD here! Seriously...I think this FX-8120 was the last chip to be made before the weekend or the first after a long weekend, LOL.. Well.. Not really laughing, maybe a tear or two...You plan for months. read reviews until you need glasses and then you purchase the equipment and get all excited when you build your rig. Then, sigh... a big disappointment when your equipment fails... I have been a loyal AMD fan since the K6-2 series.

Just to let you know I had to return one of my monitors because of stuck pixels and my H80 because it leaking! So, I really shouldn't be too surprised that something else has gone wrong!!!

I'm pretty sure if I raise the voltage anymore I will get another BSOD.

Any suggestions?????

Thanks,

I have 1.32v with 4100mhz. Can't OC higher because CPU temp will be higher than 62*c and it will cause throttling.

Temperature really isn't an issue with me, hasn't gone past 41*c.

I think youre doing too many things at once, and thats why youre having so many problems. Your almost at 4.7GHz there, with only 1.41V. Dont expect to get the same results as Cmac. Hes part of a few that can get those clocks with such low voltages. I too tried to duplicate his settings with 2 different 8120's, and could not do it without more voltage.

Stick to overclocking using the MULTIPLIER ONLY. Set the FSB, NB, and HT back to normal/auto.. Put all the voltages, except the CPU Voltage, back to stock. Are you getting 1.41V under load? If so, set your multiplier to give you 4.4GHz. Test with prime 95 blend for 5 minutes. if its stable, give it another multiplier bump and see if it its stable. If its not stable, give it another voltage bump to 1.42V under load, and test again.

Check all your voltages with HWMONITOR.

Check all your voltages with HWMONITOR.

When you say "1.41V under load", do mean when I'm at stock frequency (3100MHz)?

Ok, multiplier only...

I can tell you this, the system is stable at 4.0GHz with only the multiplier changed running Prime95. As soon as I try 4.1GHz, it locks up! for me to get 4.1GHz stable I have to increase the voltage and even then, half way through prime, I have 2 cores fail but the test continues with the remaining cores.

My issue is even at 4.1GHz I can not get a stable stress test with only adjusting the voltage where as it seem every other person doesn't have a problem.

That's why I think there's an issue with one, the mobo or two, the cpu! I have stressed the ram and it's fine...Maybe it's frustration talking!

Thanks for the info...

Ok, at 3100MHZ under load CPU voltage is 1.3125V. That's running Prime95 blend mode. The voltage is fluctuating from 1.237 to 1.3125
I used AMD's Overdrive utility to get that. CPU-Z shows 1.296V which I think is wrong. It's fluctuating from 1.232 to 1.269.

Sorry, I just reread your post. Using HW Monitor Min voltage is 1.22v and max is 1.30.

4100MHz with only the multiplier load voltage is 1.36v but the system locked up about 2 minutes into the Prime95 blend test.

Anymore advice... Thanks!

Update:

4100MHz with the voltage at (+.150) in the bios ran p95 for 5 min and it was stable. Voltage max in HWM was 1.41V and temp was 32c.

AOD utility voltage max was 1.3125v and temp was 43c.

I have an issue with software packages no registering correct values so to be safe I'll use the higher one.

Next, 4200MHz...

Well i don't know how much it helps but i'm using only the multiplier and custom memory profile @ 4.4 Ghz (I can probably go higher) and my voltage is no more then 1.275 ~

These FX chips seem to vary much.

Some people seem to be able to OC on low voltage like above^^

Mine must be a really below average piece of silicon, as it takes me about 1.5 volts just for 4500MHZ (24/7 stable), and near 1.7v for 5GHZ to even be bootable. At least one good thing about my chip is that I can do a 3000MHZ CPU-NB 24/7 stable

I would suggest you start raising voltages, and don't be shy about it. Start with Vcore. Start in small increments and take it as high as you feel comfortable. When you run out of luck there, move on to CPU-NB, and also your chipset NB (HT).

Pay no attention to the voltage reading in AOD or Core Temp, as they are reading the VID (program voltage), and you have overridden that manually in BIOS. CPUID will give an accurate reading.

I just was stable @ 4200 MHz with the voltage increased to (+.175v) in the bios. PC Heath status has the voltage at 1.424v. CPU-Z was at 1.328v.

If CPU-Z is the most accurate indicator, I'll go with that since is seems to be the de facto tool for OCing! So, no more AOD!!!

What about Temperature. What's the best tool for that?

Thanks for your input!

Cheers,
