PC Randomly Restarting after installing new Ram!

erocker said:
Often, XMP or the motherboard won't supply enough voltage to the RAM (sometimes, but not as often too much). With XMP enabled, go back into your bios and see what the RAM voltage is actually reading. If your don't have that reading in the bios try a program like Everest or some other utility. If it's too low, raise the voltage (small steps) until at the proper voltage.

All seems ok running the 4 sticks at 1333mhz. So now I have followed your advice, the dram voltage was reading 1.45v while sat in the bios, do I need to monitor it while under load? I have manually set it to 1.5v which it displays on the sticks themselves, is this correct?
 
I will try again with the last suggestion and if it fails I will just revert back to the slower settings and be done with it. As long as I can do my usual stuff I don't mind. Plus I'm sure you guys have better stuff to be doing haha! Do appreciate everyone's input though :)

Main reason I manually set my RAM to 1.55V

You need to set that ram to the recommended voltage of the fastest set.

my ram uses 1.6 if I have it at 2400 it requires 1.65

Yeah, that's correct, but with my RAM/Mobo for example, I have to set 1.520V to get an actual 1.5V
 
I tried 1.5v, 1.510v and 1.520v with the ram running 1866mhz and stock timings 10-11-10-30 as displayed on the sticks themselves and was still getting crashes every hour or so. I am now trying at 1.530v .......as I was writing this my pc died again, no blue screen, but in my event viewer, I keep getting the critical error Event 41 - Kernal-Power! I'm not sure that helps in any way. Where do I stop with upping the voltage? I would rather run lower speeds than break anything

Just to add, when It crashed last, My PC was not under load and all temps were low
 
Try turning up your cpunb volts a bit this made mine stable same incremental steps as memory until stable.
Kernel power is normally CPU power cut or tripped it's likely the last step of a lockup(I've had this a lot with an unstable oc like your saying) I ended up at 1.35 cpunb volts to get those memory clocks stable.
I've ran my memory at 1.55(1600-1866) most its life for stability except at 1333 and as high as 1.65 with no issues while benching.

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?
 
Its not your PSU man...

I highly doubt the mobo went bad either... that would show in your testing...

Hmmm not too sure then, Im monitoring all my temps each time, GPU goes as high as 80C while gaming and idles at around 40C, Cpu never goes above 60c and inside the case(system temp) seems to always be below 50c. I guess I just try tweaking setting each time it crashes

Try downloading a soft called Hwinfo64 from the publisher it has better interrogation and read back of all temps and volts I use it we can then compare, also dig out AMD overdrive software because it tells you the chips exact (well for it) per core T junction temperature.
This stinks of something getting warm while gaming and 13 hrs say it isn't memory exactly but migh5 yet be tied.

Sorry for the late reply, I have downloaded HWinfo and been keeping an eye on temps while running 1866, with nothing seeming to get overly hot, it still crashes.... I've since been running my RAM, 2x 8gb sticks at 1600mhz - 9-9-9-24 and Ive not had a single restart since.... My games and software are running much better and if I'm honest I'm happy with it...... I do really appreciate the help and advice from yourself and anyone else, thanks, glad I signed up :D

So long as your happy, should be fine though I run mine at 1333 and it games fine :)
 
If they both work at 1600mhz, I would personally leave it. You wont really notice the diffrence in the 266mhz tbh.
