unusual crashing

I should also mention I had this problem *before* replacing the drives. At that time, I was booting to a traditional HDD. I'm pretty sure the drives are fine.

My complete specs:

X99 Extreme4
BIOS v3.40
Samsung 850 EVO SSD (boot drive)
Windows 7 Pro
G.SKILL TridentZ 288-pin SDRAM DDR4 3000 Model F4-3000C14Q-32GTZ (4x8GB)
MSI Radeon R9 390 Gaming 8GB PCI Express 3
Intel i7-5820K

NOTHING is OC'd.

I appreciate any suggestions and advice.

A fresh OS install, as Wardog mentioned, is always prudent on a new system but seeing as you have a new boot drive I am guessing you already did that?

X99 boards a very finicky concerning memory. Did they boot the first time you cleared the BIOS and tried booting at their JEDEC default?

G.Skill doesn't list any mems above 2666 for this board.

That's not to say they won't work, just that G.Skill themselves hasn't tested/qualified those sticks on it. Hitting 3000 on a stock X99 non-OC'd board is a steep steep hill to be asking of it and your processor and that's why I asked if they will initially boot from a cleared BIOS at JEDEC. Heck, hitting 3000 on an OC'd one would prove hard to do.

Have the mem in the correct slots? Can you even get into the BIOS?

No problem that I know of. That's how I set all mine up when they leave here.

I could buy a couple of sticks of "approved" RAM to see if that helps with this, but only as a last resort. This is why I was hoping MemTest86 turned up some errors, but it didn't.

I'm wide open to suggestions here.

Doesn't mean they will or won't work, even  at a lower initial boot. Only that setting XMP doesn't work on the X99. Too, you'll  most likely have to adjust other voltages seeings they don't have proper X99 XMP settings. Odd. I just cut and pasted the link I posted and it's working fine here. Oh. It runs for a month or so  huh? Hmmmmm .... I was going off this was a new build giving you fits. Is the board/processor OC'd while this happens? Specs please. Of your system and generalize the OC if any.

My specs again:

X99 Extreme4
BIOS v3.40
Samsung 850 EVO SSD (boot drive)
Windows 7 Pro
G.SKILL TridentZ 288-pin SDRAM DDR4 3000 Model F4-3000C14Q-32GTZ (4x8GB)
MSI Radeon R9 390 Gaming 8GB PCI Express 3
Intel i7-5820K

NOTHING is OC'd.


I've *never* OC'd anything with this build.


The disk read error is somewhat intermittent. Yesterday, for example, Windows gave some errors, blue screened, reboot and gave the error.

I ran MemTest86 and found nothing. Reboot it manually, then Windows automatically ran ChkDsk and that found a lot of errors and booted fine right after.

I was rendering a 3D scene for work, went to bed, and over night the PC crashed and rebooted again. Right now I'm seeing the disk read error again.

The error is intermittent, but getting more frequent.

I bought the parts for this late August last year and probably didn't see the first problem for a few months. Now, the PC is unusable.

I've checked the power consumption and it's never gone over 300 watts with an 850W power supply.

CPU and case temps are well below limits, too.

All I can think of is RAM unless there's something not right about this board.
