Hello,

Sorry for asking a question on such an old post,

To have the system stable at that voltage did you have to disable voltage monitoring?

Run Intel burn test on high it'll freeze. If not - it'll still fail prime.

Stable in cinebench isn't really all that stable. Hell encode a bluray it will likely load it harder than cinebench. I do imagine u can play most games if that's all you do though.

About to give mine one more run to try for 4800mhz (200mhz underclock) so it matches my Intel rig (800mhz overclock) cause I'm ocd. At this point I'll settle for 4.7 though.

Been trying to get it prime stable on a crosshair for months on and off. Blew my power bill thru the roof several times stressing it but always fails at some point. This is with a h100i on max, a lapped chip, and CLU tim.

Course it's also with turbo disabled and all cores at that speed (like the Intel) which certainly creates/causes more heat/power and I think many overlook. That or they assume a 10m run of aida is stable.

nice man, I believe, your CPU can hold a little higher also.

PS: PRIME 95 with OCED FX 8000/9000 series is big risk. Why? Because VRM. YOu can test stability in PRIME95 separate, it means 2CU/4C and sibale others in BIOS and after second part of CUs and cores. The FX is very, very power current hungry and typical load and current consumption is much lower than in PRIME. In practice never get the same values as in PRIME. Example 4k videoecndoing will be around 80% of stress PRIME95.

I do not tell the VRM circuit at C5F-Z is bad or something. But its not good burn it ,-). FX-8000/9000 with 1.5+V (which is safe for CPU) are one of the most current CPU ever (with OCed i7-980/990x or OCed 3960/3970x)

"Example 4k videoecndoing will be around 80% of stress PRIME95. "

Actually, for some intense x265 encodes in handbrake, I was getting higher temps than with Prime95 SmallFFT, LOL.

But again, thats saturating 8 cores with a heavy load, which almost never happens in games. The only thing I would say is that you are also adding to case heat in games by loading the GPU, so that might make up for the higher (alone) CPU temps running P95 or Handbrake x265.

Curious whether it's remained stable after 3 years. Overclocks don't tend to age well. But AMD parts are always full of surprises, sometimes pleasant surprises.
