I have had my TWIN2X1024-5400C4 for about a year now and it has been great RAM but suddenly when I turned on my computer one day my BIOS says that the RAM had given a SPD error. Instead of setting the SPD at 4-4-4-12 that the RAM is rated for it set it at 4-5-5-15. I didn’t think it was a problem because a looser set of timings shouldn’t give me any problems, but when I boot into Windows I get about 15-25 seconds of Windows use then the computer does a hard reset and that just loops over and over again. I tried changing the setting on the RAM to the rated settings and that didn’t fix the problem.


I have since replaced the motherboard, processor, hard drive, power supply, video card, CD-ROM drive, and all of the cabling. All of the different configurations report the same 27000-36000 errors in the gig of RAM I have on stage 3 or 4 of the +86 memory test that I have booting from a CD that I have redownloaded and burned twice.


I don’t have any replacement sticks of DDR 2 memory so that is why I went to such lengths when I was reasonably sure it was a memory failure from the start. If there is anything you would like me to try I will but I have pretty much exhausted any ideas of further isolation of the problem.


Starting system:

Intel BOXD925XCVLK Socket T (LGA 775) 925X ATX Intel Motherboard


Intel Pentium 4 530 Prescott 800MHz FSB LGA 775 Processor

ATI Radeon X700PRO 256MB PCI Express x16 Video Card


System now:

ASUS P5ND2-SLI ATX Intel Motherboard

*NEW* Intel Pentium 4 530 Prescott 800MHz FSB LGA 775 Processor

*NEW* Antec TRUEPOWERII TPII-480 ATX12V 480W Power Supply

Different video card that’s known to work in another computer.

Please set the Dim Voltage to 2.1 volts and then set the timings manually to the tested settings for the specific module you have, and then test the module/modules one at a time with www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.
