*Dead* XMS2 Dominator CM2X1024-8500C5D

I bought CM2X1024-8500C5D in January 06 and one has begun to fail, i recently did a memtest about a month ago stating there is an error with the RAM, today it totally died I was unable to start my computer so I took out one of the modules and the computer started to boot, I turned off the computer and replaced the module with the other one, the computer refused to boot entirely. I have the defective module with me, please advise of any further actions I can take to get a replacement for this module.

 

XMS8505v1.2

I'm just about to run memtest on the working module however I was unaware that these dominator's were suppose to run at 2.2v could that be the problem? I'll try after my memtest my mother board is a gigabyte GA-N680SLI-DQ6, and also for some reason it detects my optimal defaults as 5-5-5-18, whats wrong there?

The motherboard reads from the SPD and the SPD is the JEDEC standards. You have to set the DRAM manually to 5-5-5-15 and 2.2v. Indeed, if you are not running at least 2.1v on this DRAM, you will have issues. It will not run with the JEDEC standards for DDR2 DRAM. It is of an Enthusiast level high end dram and need more voltage to run correctly.

 

I do think you mean TwinX2048-8500C5.

how do you know what your voltage is running at? and my ram says right on it CM2X1024-8500C5D

 

UPDATE: I've managed to up the voltage by +.4 however every time i do I get long continous beeps which is defined by the motherboard manual as DRAM error, Please Help

Errors in test 5-8 would normally suggest some other problem, and please tell us the exact BIOS settings you have set for CPU and memory and the Make and model of the MB.

 

I have a GA-N680SLI-DQ6 CPU everything was running at stock, however RAM was set to 2.1v (+.3)

 

UPDATE:

I just ran memtest again on stock settings with everything (which sets my mem voltage default to 2.2) and I get an error in test 1

Thank you very much for your help, however I was wondering if you think I would have any problems running four sticks of the dominator ram (all of them will be the one I'm currently using), I'm using vista, it's just that I've read that sometimes some computer aren't very happy with 4 sticks

Hi guys i just have a few questions... right now i have a Dominator PC-8500C5D which is faulty and going in for replacement.. what i was planning to do was Buy another 2GB for now so i can still use my computer and when my new RAM gets back ill have Four gig. Now the issue i have is i heard there are different REVs to this RAM

CM2X1024-8500C5D

........................XMS850Xv1.X...MICRON.........64Mx8...Rev.D

........................XMS850Xv2.x...Qimonda........64Mx8...70Nm

 

thats what i got off the another forums i am currently righting to my question is if i bought one pair and they are V1.X and Corsair sends me back V2.X will i have compatability issues??? also this Ram is rated at 2.1volts right??? so does this mean i must go into bios and set my DDR2 Voltage to +0.3 for it to run correctly or should i just leave it on auto???

THanx guys

any advice would be awesome

Rob

 

PS: BTW that RAM james_k is talking about is actualy mine and he posted on my behalf

They may or may not be compatible together, however if you attempt to run them together, make sure you have the latest BIOS for the motherboard. I would recommend setting the memory voltage to +.03v and manually setting the timings to 5-5-5-15 (CAS-tRCD-tRP-tRAS). If you are using 4GB of memory with Vista then you will want to make sure you have the following patch from Microsoft: http://support.microsoft.com/kb/929777.
