I’m in the process of tweaking / upgrading my PC for better performance. Just a minor upgrade as I think I can still make use of the old AMD FX8350 on my daily work, at least for a while. I’ll wait for the next year’s AMD CPU releases and then decide which direction to go next.
As of now I managed to overclock the CPU to a stable 4.6GHz at 1.44 Vcore. Cooler is Noctua NH-D14 which keeps the CPU under 60C. RAM is 2x4GB @1866MHz, planning on upgrading to 2x8GB. There’s room for improvement so I’ll get back at it.
I initially had 2 drives (an SSD with W7 and an SSHD with Linux), so I could boot into W7 and make use of OCCT, Intel Burn Test and other software to stress test the CPU. Unfortunately the SSD failed so I had to test the overclock stability in Linux. Was surprised to see Linux (still) doesn’t have benchmark equivalents, at least not reasonable ones. I admit I didn’t search too far and I did find mprime which is the Linux version of Prime95 and it is actually pretty good. Even though it doesn’t have a GUI, it’s pretty easy to use — download, extract the tar.gz and run the mprime binary from a terminal, then select an option from the menu. It has several features, but I didn’t play with them. Not yet at least.
I barely found a CPU-Z-like app available for Linux and was happy to see there’s a CentOS 7 (my current main OS) precompiled binary. It’s available here.
CPU-Z is a GUI app, but it doesn’t display important info such as voltages so I have to use these commands instead:
watch -n0.2 'cat /proc/cpuinfo | grep MHz'
watch -n0.2 sensors
I’ll investigate some more and keep posting what I find. Hope this helps.
