Crash.asdffdsa Posted February 18, 2008 Share Posted February 18, 2008 I purchased 2 Gig's of Corsair 8500C5D last Feb of 2007 from NewEgg. I was never able to get the memory to run at 1066 without Windows crashing. I lowered the MHz to 800 and tightened the timings up to 4-4-4-12 1T. Windows ran flawlessly with theses settings and never crashed. This Feb. I decided to upgrade to 4 GB and purchased two more sticks of the exact same memory from NewEgg. When I looked at the new sticks, the sticker said Ver. 3.1. When I installed them into my system, I pulled one of the older sticks out and saw the sticker read Ver. 1.3. With all four sticks installed I have to set the timings to 5-5-5-18 and the speed to 800 in order to prevent Windows from crashing every time. The new sticks want to run at 1066 and not at 800, but that is the only way I can get the older sticks to work correctly. Should I RMA back the old sticks? Thanks.

bigbuck08 Posted February 18, 2008 Share Posted February 18, 2008 Because you have all four DIMM slots populated, what you are expierencing is pretty much normal. There is an added stress on the motherboard with the extra RAM and it cant keep up with it. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 19, 2008 Corsair Employees Share Posted February 19, 2008 With the old modules try testing them one at a time with the following settings: FIRST THING CLEAR CMOS!! Load Setup/Optimized Defaults Memory Voltage: 2.1v SLI Ready: Disabled FSB Memory Clock Mode: Unlinked FSB QDR MHZ: Default/Auto MEM DDR MHZ: 1066MHz TCL: 5 TRCD: 5 TRP: 5 TRAS: 15 Command Per Clock: 2T TRC: 28 If one of them passes and the other fails, then lets get them replaced. With 4 modules you may need to overclock the motherboard in order to get them all running at 1066MHz (or you can set the frequency to 800MHz and not have to overclock the motherboard). But first lets see if your old modules will run at their advertised speed. Link to comment Share on other sites More sharing options...
Crash.asdffdsa Posted February 20, 2008 Author Share Posted February 20, 2008 Ok, just to be safe I tested all four sticks one by one. Three out of the four passed, the only stick that did not was one of the older versions. I re-tested it again to make sure and it failed a second time, so the stick appears to be bad. I will submit a online RMA request. Good thing I saved the packaging the new memory arrived in...Thanks for all the help, I appreciate it. Link to comment Share on other sites More sharing options...
