Ram unstable at rated speeds

[cried22]

Looked everywhere for this issue and couldnt find it. Just built a new pc with a 6700k, Gigabyte gaming 7, 16gb of 3200 Gskill ram, 650w power supply and 1070 graphics card. Really excited about it. So this issue is with the ram.

 

At 2133 everything runs fine. Anything higher than that, even 2400, and the cpu will fluctuate between 2.0 amd 4.2 and the system will freeze. If I leave it at 2133 and disable the xmp the cpu hums along at 4.2. I can even overclock to 4.6 and it's still stable. Enable xmp and it all goes to shit. Has anyone else had this issue? Any tips?

anything above 2133mhz for skylake is considered as overclocking by intel therefore there is no guarantee that the CPU controler within your skylake processor will work with anything higher than 2133mhz...it usualy does...but sometimes it doesn't.

RAM OCs can cause CPU OCs to go unstable (and vice versa). For starters, can you turn XMP on with stock CPU speeds and have it stable?

The cpu is not stable at stock speeds when xmp is on. Do you think returning the cpu to amazon and getting another one would solve the issue? Or should I return the ram? Thanks for your help

the problem is very likely coming from the CPU...cause the RAM might not be fully stable at it's rated XMP profile...but your FAR from that...so unless Gskill messed up real bad and sold sticks from a much lower bin as being 3200mhz (unlikely) then it would mean the memory controler on your CPU is pretty bad.

How is the CPU in general? can it overclock a fair bit if you let the memory run at stock?

It could be:

1. RAM is faulty. It can happen, you know...
2. CPU's IMC is crap and can't handle 3200mhz. It can happen, you know...
3. Your mobo's not playing nice with your specific CPU and RAM kit. It can happen, you know...

I could recommend swapping out 2 of those parts and end up getting wrong, that's just how random this could be. Try setting XMP and just changing the frequency to 3100 / 3066 / 3000 rather than the standard 3200. See if that helps.

Cpu is awesome in general. Really like it. Got it up to 4.6 totally stable with xmp disabled. Scared to go any higher because I am new to overclocking.

what i would do is revert the CPU to all stock settings...then manually try to raise the memory clockspeed slowly one notch at a time and see where it fail...if you havnt tried already.

 

Also, a good idea would be to test with a single stick at a time...and try to find the ''maybe'' bad stick.

i think you have more testing to do to figure this out.

ok thank you. going to do it now
