FX-8350, Sudden Temp and Voltage Issues when trying to raise multiplier:

post #1 of 11
Thread Starter 
Hey Guys,
New here, thought i'd give a post to see if you guys might pick up something i've missed, which is highly likely.

Running Fx8350 with hyper 212 evo with 2 Fans on a Sabertooth 990fx R2.0 Board Bios 1302.



In the picture i've highlighted the current clock im running on. It runs at 4.6Ghz and is quite cool, as far as i've tested it, under 50 degrees in a prime small fft test. However as soon as i try and attempt an OC of 4.7Ghz, i generally just get sumout errors. Just a bit confused because i can't see it being a volt issue at the moment, as voltage is well under 1.55V, nor can i see it as a temperature issue as my cpu is well under 50degrees. Let alone 62 degrees. Thanks alot, hope to hear from some of you smart ones.

You can see my other tested and failed overclocks in the note in the photo

Thanks biggrin.gif

I would try bumping the voltage up a step or two.

I attempted that, but didn't see much point of going past 1.45V because for some reason as soon as i leave 1.41-1.42 ish, temps soar into high 50's low 60's

I considered that, but it just seems unusual to have around a 14-15 degree temp jump from 1.428-1.4anythingelse

These are 8 core cpus man, ya trying to push a 700mhz overclock on a £30 cooler

you start to see temps rise 4.6/4.7+

We've seen quite a few evo owners come through the vishera thread and they all have got the same problem of trying to push too far thumb.gif

Same issue I had with my h100i and that is why I went to custom loop. As soon as you pass a certain threshold (depending on the cooler) these CPUs heat up real fast.
