Having Majpr Issues with G-Skill RipJaw Memory 2x8GB

[Retired]

I have a Maximus IV Gene-Z Like the title states, I don't get it. It works for a while but then I stare having all kinds of freezing and boot issues after some kind of update. It doesn't matter to me what update because it should work no matter what. I am using bios 902. The RAM is G skill Ripjaw 1866 F3-14900CL9D-8GBXL. I've called Asus, and their answer was basically " I don't know" G Skill said the RAM is compatible with this mother board. The funny thing is only one stick (4GB) seems to work fine for the most part. I have already send back one MoBo and set of ram to receive new ones. I was having an even worse issues with the first MoBo as I could not even get it to boot. I've cleared CMOS I've also set the memory freq in Bios to the 1866 the RAM should be instead of 1600 the board sets it to. That helped a little but still no dice on a stable system. I'm super frustrated. Please Help

I "had" a similar issue with similar RAM. I have the G.Skill F3-17000CL11D-8GBXL DDR3-2133 PC3-17000 4096MB x 2. When I first loaded the computer up I let the memory go at 1600 by default. I wanted to get everything up and stable, then work on increasing the speed of the memory and overclocking. Everything was VERY stable at 1600. I wasn't sure the correct or best way to increase the memory to the rated speed of 2133 so I went to G.Skill for support. I had complete confidence in both the MB and the RAM, just didn't know how to get them working together at that speed. G.Skill told me about the setting the RAM to XMP - Profile 1. That immediately looked good but then I would get BSOD every time going into Win 7. G.Skill told me to set DRAM Voltage to 1.5V and VCCSA/IO to 1.1V, I got the same result. Next they asked me to use MemTest86 and test 1 stick at a time. Both passed individually. Then I put both sticks back in and tested the pair in dual channel, both went through 3 passes fine with no errors. The last recommendation from G.Skill was to reload the OS as it may be corrupt.

That is the part that completely blew my mind. The OS wasn't corrupt. I had rebooted MANY times loading many different drivers and all of my software from scratch. Plus many windows updates and it was very stable. For some reason, reloading after making those settings DID in fact solve the problem. The system is up and running great at 2133 although I don't understand why I had the issue. I would have expected to be able to simply change the parameters and have it work fine.

Thanks, I appreciate the input. I can use some of what you went through to my advantage and it should save me some time on the phone with asus, terrible support. The one thing that bothers me is that you had no stability issues at 1600. It's wierd, no problems with single channel but dual channel I have all kinds of issues. What a pain, a brand new computer and all these problems. Anymore help would be appreciated.

I hope you get it figured out, I know it's frustrating. I'd recommend testing 1 stick at a time with MemTest86 version 4.0a in DIMM slot A2 (recommended in the manual). If 1 stick works pop it out and try the other in the same slot. If both work, put 1 in A2 and the other in B2 (the red slots). If yours didn't work at 1600, maybe 1 stick is bad.

Also, did you go into the DRAM Timing Control and set teh memory timings to the spec listed for the DRAM? I had to change those settings to 11-11-11-30-2 for my RAM.

use the XMP profile, don't set it manually.
Should work fine.
