PX736G2000ELK and Asus P6X58D-E
I have an Asus P6X58D-E mobo, Intel i7-930, and PX736G2000ELK RAM which have been working reliably for the last 8 months using the XMP settings for DDR3-2000MHz. Suddenly, the system has become unstable at those settings (CPU not overclocked). The only way the system will boot and remain stable is by running the memory at DDR3-1066MHz. I've tried everything in between and the system is unstable (1333, 1600, 1866, etc.).
Cooling is very adequate. The system is installed in an Antec P180 case with 2 full size fans in the front sucking in, 2 fans in the back exhausting up and out, and 2 full size fans mounted on a Hyper 212 cooler in push/pull configuration to cool the CPU. The RAM itself has heatsinks installed.
Any ideas on this specific combination and how I might be able to resolve it? Asus mobo BIOS is 0701. Cheers.
Can try applying all of the latest drivers?
Furthermore, try running a Memtest at the XMP speeds.
Memtest can be found here: http://www.memtest.org/
3-4 Loops should be fine. However, try to run it overnight if possible. Please let me know if you find any errors.
The thing with DDR3-2000 on X58 is that it can be a hit-or-miss spec...
However, if you previously had it working prior, then this could indicate that the memory might have became faulty... please advise upon testing.
I'm unable to get it to POST at DDR3-2000. In fact, I'm unable to get it to POST at anything beyond DDR3-1066. When it does momentarily post at DDR3-1333 or higher, the machine shuts off and restarts by itself after less than 30 seconds of operation.
I ran Memtest at the 1066 speed and memory checked out fine. System doesn't stay on for long enough to allow Memtest to complete at the other speeds.
What likely happened is that the memory became faulty if you can't even get the timings to stick. I would recommend a replacement under warranty.
To Initiate an RMA or items relating to warranty, please visit this link here and under ‘troubleshooting’ select your product from the dropdown box and fill out the info (look at the bottom for ‘start a technical case’):

Actually, it's not working out very well. Support authorized the RMA, but wants to substitute PSD38G1600KH, which is not a high performance replacement. It doesn't even have an XMP profile. I suggested PXD38G1866ELK, but haven't got a response... the ticket is now closed!
Please note that the ticket is only in the Technical Support end.
