OC newbie having trouble
Posted: Wed Jul 02, 2014 2:20 pm
Hi all, I'm new to overclocking and having a bit of trouble.
The computer:
Rosewill 550W PSU
ASUS M5A97 R2.0 mobo
AMD FX-6300
8 GB of G.Skill DDR3-2133 9-11-10-28
MSI GTX 650 Ti Boost
92mm tower CPU cooler (Zalman)
Linux Mint 16 Xfce
Obivously there's nothing extreme about this setup, but I would find a bit more single-threaded performance handy, and the FX-6300 should have some headroom for it. I did some reading, tried some stuff, and ran into two problems fairly quickly.
First, Prime95 crashes even at all stock settings. The only changes made were when the computer was built, and that was just setting up the RAM for full performance (I've since double-checked everything is within spec). I do some gaming with this machine, and it's always been stable for that. Running Prime95, the computer hangs after ~2 mins, with the CPU temp >50*C (it looks to stabilize in the upper 50s). Looking around the internet, I've seen some references to AMD and Prime95 not getting along well, but that strikes me as implausible at best.
Second, I can't seem to get a Vcore reading with the OS booted. lm-sensors seems to be the standard tool for this on Linux, but I've fully set it up and am getting some rather garbage readings (these are all the voltages returned):
in0: +2.82V
in1: +2.87V
in2: +0.88V
+3.3V: +3.29V
in4: +2.47V
in5: +2.52V
in6: +1.54V
3VSB: +1.82V
Vbat: +3.36V
Everything returned from that interface (it8721-isa-0290) looks questionable (there are also temperatures that don't change and a fan speed that's high). Other interfaces (k10temp-pci-00c3 and fam15h_power-pci-00c4) provide CPU temp and CPU power draw reliably. The temp reads 10*C low, but I can work with that.
For the Prime95 hang, everything I can think of seems implausible. The one that seems to me least implausible is a power issue, but that's tough to diagnose without post-boot voltage readings, which are non-functional (all voltages look good from the firmware, but that's unloaded).
Thanks in advance for any ideas!
