Could be that your psu isn't powerful enough to run all the stuff. whats the wattage of the psu and what brand is it?
Did you try Prime95? http://www.mersenne.org/download/
Download the 64 bit version the extract it. On the pop up click "Just stress testing" and then from the choices click "Small FETS (minimal ram usage)"
if it crashes it's probably not your ram.
Prime95 stress test is bad for x99 cpus. Don't use it.
I still think you have nothing to lose by giving the system agent voltage a small bump. Nothing major, just a little bump of say 0.015 or so, won't hurt, but if it's the imc it might just need a little extra to be stable (auto voltage doesn't always get it right, especially on x99), if nothing, then meh, you've lost nothing except a small amount of time.
Just to be on the safe side unmount your board from the case and test it on a workbench. Be super careful about doing that though.
Also set all bios setting to default and remove any overclocks etc.
Lastly check if there are any updates to the bios and instal those, be careful though messing up a bios can brick your board.
When its running on a bench using one ram module at a time see if it runs without crashing or freezing on idle and then stress test it and see if it has issues. If you rule out any shorts, bad ram, bios issues etc it could be your cpu that is having issues.
i ve tested all my rams... with booting methods and botting with one ram stick of each out of 4 was no success.. cause the pc didnt even sometimes post with every rambrick in singlechannel mode
i ve xmp enabled ^^ in single core it works.. but the ram crashes :'/
ahm... so if it doesnt work.. .should i exchange everything? ^^ (ram cpu psu)
Ok so is there an update for your bios or anything like that? If there is one check if there are any fixes for the issues you are experiencing. Also as a last resort maybe try contacting the support service for your mobo and discussing the issue with them, maybe they can give you advice that we wouldn't even think of.
opps, forgot about this.
I didn't say anything about xmp. I said to give the system agent voltage a tiny bump.
so you think i should disable the xmp
and put a bit of voltage to my ram?
Yes, for now.
No. I never said that. I said give system agent voltage a small bump.
System agent voltage is the imc in the cpu. Put memory stock, give system agent a small bump, see if it will stabilise. X99 is fussy and auto settings can frequently get it wrong. Just give the imc a little bit more (not much, maybe + 0.015 or so) and see if it will stabilise.
ohhh thank ya for the tipp!
ahm.. the only problem is .. the system can run well ... a week ... and suddenly crash... without anything ^^ thats ...not great i d say...
i mean should i maybe see a great difference ... compared to now? after setting the voltage a bit higher?
Might do. Not saying it will fix it. Just that X99 can be very fussy with memory and quite often giving the imc a little bit more voltage will stabilise it. Might not, but at this point, you've tried everything else, and it won't hurt to try just giving the imc a little extra and seeing if it helps you. If it does, then you can go from there trying to get xmp profile working, but at least you will have a stable base to start from.
i ve a problem .. which one should i pick
the cpu system agent voltage offset mode sign or the cpu system Agent Voltage Offset?

corrently it s on 1.152 V to 1.160... its changing
Voltage does tend to fluctuate slightly on auto on the bios screen. Nothing to worry about.
I've not used Asus in a while, but if the bios looks like this
https://edgeup.asus.com/2016/06/17/broadwell-e-overclocking-guide/5/
Then you leave the offset sign at +. Change auto to adaptive, then another box should appear letting you put the offest voltage you want (start low, like 0.015, you might not be able to put exactly that), which should give + 0.015V on top of whatever the board gave as default (so based on what you said, you'll probably end up at 1.175ish, which is still well within safe voltages for the imc.
