GA-P35-S3 and Incompatible Corsair RAM


Recommended Posts

I originally posted this thread here: http://www.asktheramguy.com/v3/showthread.php?t=63036

But i figure its in the wrong section.


I am currently building a PC for a friend, and purchased a Gigabyte P35-S3, and 2x1Gb Corsair Twin2x XMS2-6400 (5-5-5-12 timings).


I installed it with the following:

Antec Sonata 3 case w/antec 500w PSU

Radeon 2600XT

Intel C2D E6550


However, when the Corsair RAM is installed, the system doesnt post, and i get 3 long beeps, then pause while the system tries and boots again, and then the 3 long beeps, and repeat.


i tested with some other branded ram and the system posts fine.


Just wondering why there might be some incompatibility as i am running the same RAM in my Gigabyte P35-DS4 system fine.


i was thinking of doing a BIOS update with different RAM and try the Corsair RAM again.


Ive also tested the Corsair RAM in another system and it worked fine.


Any ideas?


Any help is appreciated.

Please make sure that you have the latest Bios version and then load setup/optimized defaults and set the Dim Voltage to 2.1 volts (+.2 Volts W/Giga-Byte) and then set the timings manually to the tested settings for the specific module you have, or if you have Value Select "BY SPD" and then test the module/'s one at a time with http://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.

Ok, i updated the bios to F5, and found out that one stick of the 1gb was faulty.


system posts fine with stick 1 by itself.

if stick 2 is in the system by itself, thats where the problem exists.

funny thing is i originally tested 1 stick by itself but it must of been the bad stick, and i just assumed the ram was bad without testing the good stick by itself.


thatll teach me!


its new ram and i got it from where i work, so ill just do a direct swap for it, and it will be fine.


thanks for your quick reply and input, its most appreciated.


im just glad i finally got it sorted :)
