post #16561 of 22287
4.3 at 1.29v here as well. It is stable with p95 28.7 1344k fft. I just don't think these chips scale as well as people think they do. I'd like to see some of these guys show 1 hour of 28.7 1344k ffts still be stable at 4.6-4.7ghz and 1.2v. I just don't see it happening.

They are what they are. If you want to be FMA/AVX stable you have to sacrifice frequency for voltage. That seems to be how this platform is.

What is stable?

Running prime95 for 24hours, or never crash on folding?

I`m cool with 2 hours OCCT max. If it won`t crash on me while gaming/folding then i`m good. I don`t need a 24hour prime95 stable CPU.

Hello

Fixed.

Im good with 1hr of realbench, 1 hr of aida64 with cpu, fpu, cache and memory checked. Then another hour of just cache and memory. One hour of GSAT and i also let hci mem test run overnight for 450% 32Gb. With 16Gb it went to 900% for a overnight run. After all that i say it's good. haven't had a single crash / bsod in any program i run.

Used in the same manner? yes you're correct. No other apps hammer FMA as much as prime However, if prime95 stirs up a floating point error using FMA/AVX due to heat and/or voltage problems it will happen in other applications. It's just a matter of when.

If the FMA instruction set is unstable, its unstable. If you never use an application that utilizes FMA you're fine. Otherwise, it will fail... its just a matter of when.

Wow i just ran aida64 GPGPU test and it spiked my temps to 91c for a second.
hopefully it was not damaged redface.gif

You're likely fine. The chip will automatically go into thermal throttling to keep it from nuking itself.

Although, you may want to evaluate your cooling solution!

you can run the Hash, Julia, mandel etc components individually from within AID64 main benchmark menu...

Temps dont break 75c in aida64 or realbench. Those are the kinda temps prime 95 see's. Not sure what instruction set single precision julia and double precision mandel uses but it causes crazy spike in temp.


My cooling is more than capable i have two hwlabs Black ice GTX radiators in push pull 2350rpm

Temps are fine when ran like that. I think its the GPGPU thing that really spikes the temps.
