Help!
I am experiencing non-stop (as many as 4-5 per hour) lockups/crashes when gaming. Sometimes the lockups are sporadic (can go a day or two lucky,) usually get a few per day, and sometimes am mercilessly crashing all day. The system is generally stable outside of gaming (only frozen a few times when not gaming in the last year) and is able to POST reliably as well. The lockups are never BSODs, just the system freezes and exorcist noises come out of my speakers. Sometimes the system will then reboot after 15 seconds or so, but most of the time I have to hard reset the computer. Games affected have been... all of them: Left4Dead2, Skyrim, Assassin's Creed: Revelations, Starcraft 2, Battlefield 3, Star Wars: The Old Republic, Mass Effect 2 & 3, etc etc.
My specs are as follows:
RAM: 16GB (4x4GB) Ripjaws X F3-12800CL9D-8GBXL (Running with XMP @ 1600MHz, timing: 9-9-9-24-2T)
CPU: i5 2500K @ 4.2 GHz (have experimented with the stock 3.3GHz up to 4.2 and everything in between)
Motherboard: Gigabyte P67A-UD3P-B3 rev 1.1 running latest F9 BIOS (have experimented with previous builds since F4 to no avail)
GPU: Gigabyte 560GTX Ti OC (have swapped in a Radeon HD3850 and Geforce 8800GT as well)
SSD: Intel 510 120GB (latest firmware)
PSU: Antec Truepower New 650W
OS: Windows 7 Ultimate SP1 64bit
GPU Driver: 301.42
DirectX 11.0
I am 99.999% certain it is the memory that is posing the issue as I have swapped or RMA'd every component listed above except the RAM (I had erroneously assumed until now that the RAM was probably fine because it had passed a couple overnight runs of memtest86.) I have also tried various permutations of fresh OS installations and various driver versions with no success. CPU and GPU both pass prime95/Furmark respectively with zero issues, and temperature monitoring/logs over the last year show that temperatures are stable and not a cause of the crashes I'm experiencing. Windows Event Viewer/Log also shows nothing particularly crazy going on.
As far as what I've tried with the memory, as per other support posts on the forum:
-XMP/no XMP (no difference)
-Disable XMP and manually set timings to 9-9-9-24-2T (despite the status screen showing that the motherboard is reading the XMP correctly)
-Enable XMP and manually set timings/voltages
-Set DRAM voltage to 1.55-1.56V
-Set VTT to 1.13V
None of the above has worked. As of today I have tried dropping from the rated 1600MHz to 1333MHz (kept 9-9-9-24-2T timings and increased DRAM/VTT voltage) to see if I can get any stability at all but I won't know if it has helped until I've managed to go a day or two crash free at least. Even then, the memory would be failing to meet its specified performance of 1600MHz.
Please help! I've been pulling my hair out for a year and have gone without my computer for weeks at a time while waiting to RMA various parts to no avail. With my thesis due very soon I can't afford to go without the computer again!
