carbo Posted November 14, 2005 Share Posted November 14, 2005 We have a Gigabyte k8n ultra-sli but with Cmx512-4400c25pt the system doesn't boot. The same system with another memory have no problem. I try the Cmx512-4400c25pt on another system with MB Asus a7n8x e-deluxe and Windows doesn't start. Is it possible that this memory is damaged(but It's new,I bought it one week ago from a shop)?

Wired Posted November 14, 2005 Share Posted November 14, 2005 What speed are you trying to run them at? Link to comment Share on other sites More sharing options...
carbo Posted November 15, 2005 Author Share Posted November 15, 2005 With the gigabyte I don't know because the pc doesn't boot(amd 64 3200), with Asus(xp-m 2500) probably fsb 200*11 and latency 2.5-3-3-8 . Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted November 15, 2005 Corsair Employee Share Posted November 15, 2005 These modules may not run in that MB as they have a minimum suggested voltage of 2.75 Volts. But I would try the system one module at a time and make sure that you have the latest bios and set the Dim Over Voltage control to +.3 Volts then test them one at a time with http://www.memtest.org.

carbo Posted November 17, 2005 Author Share Posted November 17, 2005 I have only one module of Corsair with double-face. The only way to increase the voltage is to boot the system with my other module of Twinmos ddr400, then I change the Dim Over Voltage control to +.3 Volts, power off, change the module memory and power on the system. Is It right? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted November 18, 2005 Corsair Employee Share Posted November 18, 2005 If that is the only method that will work then yes. However, make sure you are not mixing the Corsair modules with any other brand. Link to comment Share on other sites More sharing options...
carbo Posted November 21, 2005 Author Share Posted November 21, 2005 I post here the reply of official Gigabyte technical support: "Meanwhile, based on DDR spec., default working voltage of DDR memory is 2.5v. and has +0.2v tolerance. But, as we know, some high speed DDR memory modules need higher than 2.7v power to work, and the spec. is over the DDR memory definition by JEDEC and the high voltage will also reduce memory IC lifetime. Thus, we do not recommend you using such memory modules with our MB to avoid unexpected H/W damage." However I test Corsair memory with memtest86 and goldmemory on my Asus A7n8x e-deluxe and I find a lot of errors, so I Know that this module of memory is damaged. I will change it.
