Unstable ASUS P8P67 WS Revolution and i7 2600K

We need some new eyes on this thread please :)

Original thread is here and is long and wordy:
http://www.tomshardware.com/forum/forum2.php?config=tomshardwareus.inc&cat=31&post=311044&page=2&p=1&sondage=0&owntopic=1&trash=0&trash_post=0&print=0&numreponse=0&quote_only=0&new=0&nojs=0

Then we moved it here:
http://www.tomshardware.com/forum/318428-31-unstable-build-failing-prime95-blend-test#t2369980

Short version,
He's built this comp but it continues to have minor issues Prime95 eventually produces a crash.

Seems he's done memtest with no issues.

I had him bump the CPU voltage offset, no joy.

Just post on the new thread if you want to help, not this one :)

    Assuming the 'Option 1' Tri-Channel set then do NOT use XMP, and instead manually set the Frequency, DRAM Voltage, and CAS Timings sometimes a QPI/VTT/VCCIO -> 1.20v helps.

    Then I noticed 'F3-12800CL9D-8GBXL' I've posted here a zillion times that those will not 9/10 run Rated in 4x4GB and to use F3-12800CL8D-8GBXM IF you want DDR3 1600 MHz speed.

    Solution 1 - Run the F3-12800CL9D-8GBXL at DDR3 1333 MHz and look at CPU-z 'SPD' for 667MHz CAS Timings and add Command Rate -> 2.

    Solution 2 - RMA RAM and get 2 sets of F3-12800CL8D-8GBXM

    Solution 3 - Get a 4x4GB Matched Set -> F3-12800CL9Q-16GBXL

    Thanks Jaquith, you are helpful and brief, as always :) I quoted you so I could copy and paste. I'll pass that along.

    I hadn't spotted the 4-pack of RAM myself. I wonder if it's really that simple? We'll see!
  3. You can try setting them manually: Frequency -> DDR3-1600MHz, CAS 9-9-9-24 + Command Rate -> 2, raise the DRAM Voltage -> 1.55v~1.60v, plus VCCIO -> 1.20v. Then 'see' what happens... 50/50.
  4. If ya wanna try something else .... My son's running the CPU / MoBo combo with Mushkin CAS 7's at rated speeds and timings ..... 4.6 Ghz for everyday boot, 4.8 Ghz (HT disabled) on gaming boot via BIOS profiles feature
  5. We'll see where it goes. If you both feel it's still memory related that's good enough for me. I've had a number of puzzling threads lately :p
