stukafox Posted January 17, 2008 Share Posted January 17, 2008 Symptoms: 1. Machine hangs at BIOS code C1 (checking memory); long beep tone sounds, indicating memory failure. 2. If a single stick is removed from memory slot 3, machine will boot normally. It doesn't matter which stick. (Setup for two sticks on this motherboard is slot 1 and slot 3) 3. Swapping sticks results in same boot failure. 4. Memtest 86 on 200 passes shows no errors. 5. Increasing voltage to 2.1v does not resolve problem. 6. Changing timings does not resolve this problem. 7. After the machine boots normally, machine can be turned off, stick replaced, and the machine will boot normally with both sticks in place. 8. Problem also confirmed on a Foxconn X38 board: exact same symptoms with this memory. If you cannot cross-ship for RMA, do not bother starting warranty; I'll buy some replacement memory from another manufacturer and request a refund from New Egg on these sticks.

Corsair Employees RAM GUY Posted January 17, 2008 Corsair Employees Share Posted January 17, 2008 If I understand this correctly, you are getting a C1 error when you have both modules installed in dual channel, but the modules each boot up fine when tested individually and pass memtest. If this is the case, then there is probably not a faulty module. First thing I would recommend is that make sure you have the latest BIOS for the motherboard, then load setup defaults and set the memory voltage to 2.1 volts. If you still have trouble in dual channel mode, then I would attempt to boot the system in a single channel configuration using both modules, and see if anything changes. Let us know what happens!

If you still have trouble in dual channel mode, then I would attempt to boot the system in a single channel configuration using both modules, and see if anything changes. Let us know what happens! A quick follow-up on where things are: - Upgraded the BIOS to the beta .12. - I've tried the entire voltage range from 2.3 to 1.8 - I can boot the system every time off one of the two sticks, but the other stick will never allow the system to boot. - I put two sticks of cheap no-name memory in the box and it booted perfectly (for reference, it's PC-800 5-5-5-18). Although the memory passes memtest86, the reproducibility of the problem with the one stick suggests that maybe that DIMM is defect in some way. I'm going to try to resolve this through New Egg for cash back or credit (since this isn't the memory I wanted in the first place). If they won't take it back, I'd like to start the RMA process with Corsair. Also, has Corsair tested this memory on the X38 chipset? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 21, 2008 Corsair Employees Share Posted January 21, 2008 Yes this memory has been tested with the X38 chipset and should be compatible with your motherboard. If you have any trouble having it replaced with your reseller then please use our On Line RMA Request Form and we will be happy to replace them.
