this is a bit of an odd one, i've narrowed it down but not too sure where to go from here. hoping for a little input!
built a new system this past black friday, its been a LONG time since i've done so and it's been an uphill battle the entire way. so far i've got it stable....mostly.
parts list:
i5 6600k (skylake), not OC'd at this time.
gigabyte GA-Z170MX-gaming 5
16GB (2x8GB) g.skill DDR4 3200 (G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Intel Z170 Platform Desktop Memory Model F4-3200C16D-16GVK - Newegg.ca)
nvidia GTX970
corsair HX650W (little old, but still works well)
system is cooled well on water, both CPU and video.
here's the issue:
i often cut power to my system when not in use for a long period of time simply to save power. old habit. when i power everything back up, i *usually* have a system lockup shortly after windows starts. reset button will not work, but holding the power button will. however, system will usually not post correctly. i then have to cut power and try again, usually works after doing this once. funny thing is, once it's going stable that's it! its rock solid. if i leave it powered and in sleep mode, i have no crashing also.
remember, being 3200Mhz DDR i must enable the XMP profile to get this speed. after updating the BIOS to latest, this setting was disabled, speed dumped down. no more crashing.
i thought i had a dead ram stick. tried each stick on its own, with XMP enabled to run full 3200Mhz. again, no crashing. this only occurs with both ram sticks installed running at their full speed. i'm rather concerned about the future...i planned to dump in another 16GB in a couple years as an upgrade path.
been in contact with gigabyte support (man they're awful!) and the response i got was interesting...they claim that the i5 6600K will only run memory speed up to 2133mhz. i was not aware of this, my error in build? am i unknowingly overclocking the memory controller badly here? being out of the loop a little....i think skylake has memory controller onboard the cpu.
also asked g.skill about this, still waiting for a response. was hoping i could get some input from some of the resident experts around here. if the case is as gigabyte states, maybe set a slightly lower speed manually might be in order? i'm mostly trying to find the root of this problem before i start overclocking.
if gigabyte support is incorrect and i need an RMA here...maybe some advice on how to talk to these clowns?
thanks guys.
