StannyMann Posted July 3, 2004 Share Posted July 3, 2004 Just bought this board and two single Corsair 512mb 3200C2. Singley, either stick will work fine in slot 1 - system boots up fine, but I can't boot both sticks in slots 1-2, 2-3, or 1-3. The system halts right after CPU post right before mem check and I have to kill the power at the supply to reboot. Also, system won't boot with either single stick in slot 2 or 3. Do I need twin memory? I thought it wasn't required for AMD64 (3200+)? Any ideas? I'm also trying to work with Gigabyte tech support, but I only get an email every 3rd day or so with questions like "is your ram ECC registered?" ___________________ AMD Athlon 64 3200 2x512 Corsair 3200CL2 Gigabyte GA-K8NS-Pro Western Digital 74GB 10,000RPM NV5900SE Antec TrueBlue 480w Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 6, 2004 Corsair Employees Share Posted July 6, 2004 Please make sure that you have the latest bios then load setup defaults and see if the system will post. In addition, in order to run 2 modules in this system they would need to be exactly matched both in part# and revision! So if you have 2 single modules please check that they are exactly the same!

StannyMann Posted July 8, 2004 Author Share Posted July 8, 2004 Ram Guy, thanks for the reply. I tried default F1 bios settings and pushing voltage upto 2.7v and still couldn't post with both sticks installed. I'm hoping that slots 2 and 3 were defective and I've RMA'd for a replacement, hopefully this will solve my problems. However, a recent reveiw on tomshardware ([url]http://www6.tomshardware.com/motherboard/20040602/memory_modules-05.html[/url]), seems to indicate that AMD64 processors do not support 2x or 3x double-sided RAM at 400MHz, only at 333MHz. Do you know if this is this an actual restriction or just a guideline? I can't find a definitive answer at AMD's website, but I'm pretty sure I've seen posts of A64 systems running multiple double-sided sticks at 400MHz. My noob ? for the day: If I have to run 2x512 RAM at 333MHz for stability, will the CPU need to run at a lower speed (multiple of 166MHz rather than 200MHz)? If so, should I consider exchanging my 2x512 for a 1x1Gb to run at 400MHz? ------------------- AMD Athlon 64 3000 2x512 Corsair 3200CL2 Gigabyte GA-K8NS-Pro Western Digital 74GB 10,000RPM NV5900SE Antec TrueBlue 480w Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 8, 2004 Corsair Employees Share Posted July 8, 2004 Yes, I would consider a 1.0 Gig module over 1 512 Meg sticks! However, this CPU or chipset should be able to run 2 512 Meg modules at DDR400 in slots 1-3 and set the Dim Voltage to 2.7 Volts! Link to comment Share on other sites More sharing options...
