Zabusa Posted November 18, 2010 Share Posted November 18, 2010 Hello. I am using the DDR3 XMS3 8gb 1333 (CMX8GX3M2A1333C9) on an ASUS M4A89GTD PRO/USB3. The system has the mem set on SPD as 1066 MHZ and at 8-8-8-20 latency. Memtest was run on the sticks individually (using USB flash drive) and did not have any errors. When both sticks are installed, memtest hangs at random passes and system becomes unresponsive, forcing a reset. Also the system will sometimes not boot at all when i set the memory speed manually as 1333 9-9-9-24 1.5v. My mobo has a memory led that stays lit when it refuses to boot. I hold the memOK button to solve "compatibility issues" even though ASUS states this is compatible ram with the board I got. If it even boots the windows 7 install CD hangs when loading files and then if I reboot the PC it wont POST and the memory LED comes on, so I use the memOK button and it defaults the mem to default 1066 with 8-8-8-24 latency. Any tips/help would be appreciated, I really need to figure this out. Thanks. Link to comment Share on other sites More sharing options...
trackrat Posted November 18, 2010 Share Posted November 18, 2010 Try setting the RAM voltage to 1.6 V. Link to comment Share on other sites More sharing options...
Zabusa Posted November 18, 2010 Author Share Posted November 18, 2010 after setting all the timing manually right? I set the timing according to the label on the ram stick to 1.5v but I will give it a try. Any other ideas if it fails? I would think having the Dram voltage set to auto would compensate for the manual setting of 1333 mhz. When it refuses to boot and I boot using the mem ok button, the POST message says overclock failed, but technically, its not an overclock snce the mem. is rated to run at those speeds :[pouts: Link to comment Share on other sites More sharing options...
Zabusa Posted November 19, 2010 Author Share Posted November 19, 2010 So, i found out yesterday when I tested both sticks in a different slot, the computer would not boot up when either stick was in the 2 slots further from the processor. I installed the 2 sticks next to each other, and the computer boots and I was able to install windows without a hitch? Now Its safe to assume the mobo is bad and I need to RMA right?

Zabusa Posted November 19, 2010 Author Share Posted November 19, 2010 could it be compatibility issues at all? I haven tried putting both sticks in sloth B1 and B2 (next to each other on the other 2 "faulty" slots) and it may work with dual channel not enabled, Officially my ram is not compatible with the ASUS board according to corsair, but it is according to ASUS.
