hey guys,

after getting to grips with the subtle oc on the GPU i am now looking to do the CPU again.

Im a little worried about the voltages, as stock the CPU temps under load so far are the mid 40c roughly.

so if someone can tell me a rough quick step to what im doing in AMD overdrive. specifically the highest voltage i should go to for? its currently at :





thanks guys,

hey guys,

so far im at 4.3ghz at v1.4000. tomorrow i will do proper stress tests but seem stable so far.

counter strike fps and large player maps have zoomed up, so i guess the CPU helps with the multi rendering of the 30 odd players and maps?

the only concerning is that the CPU temp doesnt go above 41c underload at the 4.3ghz on msi afterburner? WTF?

hey guys,

i have started tweaking the CPU through the BIOS. the problem i am having is when running PRIME95 i get this when stress testing the CPU. :

[Thu Aug 04 15:39:19 2016]
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
FATAL ERROR: Rounding was 0.4921875, expected less than 0.4
Hardware failure detected, consult stress.txt file.

what does that mean, i have uped the voltage and has not crashed but the errors on the cores are coming up?

The Hyper TX3 EVO is a very small cooler for such a warm chip.

What temps are you getting for the CPU and the VRMs? I'd be surprised if the CPU is only at 41C. The VRMs are likely to be even hotter.

If Prime is coming up with errors, then the overclock isn't 100% stable.

hey mate,

thanks for the swift reply, what do you recommend i do? do i increase the voltage, what can i test the VRM temps with software wise?

I would use something like hwinfo64 to keep an eye on the CPU temps and motherboard VRM temps. It could be you need more voltage, but there are a number of factors involved in OCing and the voltage is just one.

AMD is totally different to Intel. I know how to OC Intel, but not AMD. Jamie has OC'd AMD chips before, so if he says up to 1.5V is safe, you should be OK if you have the cooling capacity.

My concern would be the VRM temps. The FX-8 series CPUs do hammer the VRMs quite hard. Your board only has a 4+1 power phase, compared to say a 990FX Sabertooth which has an 8+2 power phase so each of your VRMs will be more heavily loaded.

hey mate,

how does this look? it is TurboBoost off and set to 4200mhz at the moment.

these temps were running stress test on prime95
