Voltage spikes would be a result from the motherboard LLC, you are on a saberkitty, so very high and greater LLC is Vboost. Not all chip like it, some chips kinda hate it.
as for ram, still wouldn't recommend mixing unless both brands and sticks use the same IC's
i would go do a serious couple hours in memtest with you sticks at current timing.
when you say shut down, do you still hear activity in your case? fans sand other spinning media? and it just a black screen?
Oh no I think you misunderstood what I mean, from what I have read 70c for the FX chips is the maximum temp you can hit before it shuts down? (I dunno there is so much conflicting information tbh I'm starting to get very confused on what is what lol) Anyway, My pc seems stable, I don't have lock up or random crashes etc, even gaming it's fine at 5GHz but it is pretty close to 1.6v so I will probably just dial it back down to 4.8 or 4.9, probably the former. What I'm confused about too is the temp spiking I just don't understand why it rises 6c with the run, then spikes 10c before the end of the run and back down. So confusing lmao
Yeah like I said in previous post. 70C is maximum sustained. FX is known for having large and sudden temp spikes that often don't last longer than a few ms. Often I never catch the spike on the monitoring software with the naked eye, but the max readings often report it. From your cooling you should be able to manage decently high OC's. Probably 5 since you have a Kitty. What sort of cooling do you have on your VRM heatsink and on the back-side of the CPU socket? Often these two things can make the biggest difference to your OC. But I dunno if there is a shutdown point for socket temps?!?! So if that isn't the case then I would seriously start to investigate your PSU as a possible cause.
Here is a pic of temp recordings from a stability test. You can see some of the quick sudden bursts in temps.

Well, you CAN buy better paste but it won't make much of a difference. Maybe 1,5-3c max.
What you can do is try to do a re-mount. Improper mounting of the block will give much worse temps then the difference from good to average pastes.
Yeah i did remove the stock paste to put the cheap stuff on and the block has been remounted twice, no temp change.
Anyway i was able to get it to 4.9ghz on 1.5v, i did however have to remove all my case panels and mount a fan to the top so that i could keep the temps below 80c. I've ordered some arctic mx-4 online and hopefully that will allow me to reach 4.9ghz without needing to remove the panels.
Also the stuff im currently using has a thermal conductivity of 1.22w/mk while the arctic mx-4 is about 8w/mk what kind of temp drop should i expect?
MX-4 is a good paste and really works well. I have used it for years! You might not expect a huge temp drop. Or you might. It is just that MX-4 moves conducts heat faster. If anything 5C max. But don't expect more than 2C me thinks. Another thing you might want to investigate is cooling your VRM heatsink and the backside of your CPU socket. Like I sad earlier this makes a large difference including your core temps. These things generally become a mandatory requirement above 4.8GHz. If you can in fact keep 4.9GHz stable at 1.5V well that is impressive because I need 1.548V for that speed.Edited by Alastair - 10/25/14 at 1:48am
