emax1ram Posted October 9, 2007 Share Posted October 9, 2007 Hello, I have 2GB Corsair XMS2 6400C4 ram installed in the yellow slots on my Asus P5N-E Sli board. I have the Intel 6750 2.66Mhz processor, coolermaster 750watt pro pwr supply, WD 160GB SATA drive. CPU-Z shows 2 GB installed but vista system properties shows 1GB. I adjusted timings to 4-4-4-12 2T, I have the latest MB bios 0703, and the latest Video card drivers for the Evga 8800GTS. I believe it's a setting issue, but I have no idea beyond that. Can someone recommend a fix. Thank you. emax1ram Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 9, 2007 Corsair Employees Share Posted October 9, 2007 Please test the system with http://www.memtest.org and see how much memory is showing! Link to comment Share on other sites More sharing options...
emax1ram Posted October 10, 2007 Author Share Posted October 10, 2007 I am new to this stuff and very nervous about running the test. Can you tell me how to run memtest. I burned it onto a DVD, and I know I have to change the boot sequence so my pc boots from the DVD drive and that loads the program, but then what?

Corsair Employees RAM GUY Posted October 10, 2007 Corsair Employees Share Posted October 10, 2007 I think you will have to burn it to CD, and then just let it run it will show the total size of memory that is show in Memtest. If it shows the full size then you might need to reload the O.S. Link to comment Share on other sites More sharing options...
DerekT Posted October 10, 2007 Share Posted October 10, 2007 I am new to this stuff and very nervous about running the test.Don't worry. This is a read-only test and makes no changes to either data or system. :): Link to comment Share on other sites More sharing options...
emax1ram Posted October 10, 2007 Author Share Posted October 10, 2007 Ok, I burned it to the DVD, disabled legacy USB, changed the boot to boot off DVD drive, but it is'nt working, it's just skipping over it and booting normally.

What am I doing wrong??!! You need to burn it as an image, not as data. What program are you using to burn? Link to comment Share on other sites More sharing options...
emax1ram Posted October 11, 2007 Author Share Posted October 11, 2007 I appreciate your help. Yeah I burned it as data, using standard windows vista explorer. By the image do you mean the unzipped iso file?? Link to comment Share on other sites More sharing options...
DerekT Posted October 11, 2007 Share Posted October 11, 2007 Yes, you need to use a program such as Nero Burning ROM and choose to burn the ISO disk image. This will burn a bootable disk. http://www.nero.com/enu/downloads-nero8-trial.php Tutorial: http://johnbokma.com/mexit/2007/01/05/burning-dvd-iso-image-with-nero-express.html Link to comment Share on other sites More sharing options...
emax1ram Posted October 11, 2007 Author Share Posted October 11, 2007 Ok, I got memtest to work with your help, I used Nero and burned the image. Thank you very much. Memtest showed 2047MB memory, just as I have installed, it showed my processor, intel 2667MHz, L1 cache was 64k, & L2 cache was 4096K. Rsrmem was 52M. Everything looked correct, memtest did all tests and no errors. I ran it for at least an hour. Also just a note, my bios shows the proper memory too. What else can it be??

DerekT Posted October 11, 2007 Share Posted October 11, 2007 Very likely a problem with the software. You are running correctly and the system is using it correctly. Download CPU-z: http://www.cpuid.com/download/cpu-z-141.zip Run it and if it shows you correctly in the memory tab which will be half of the dual channel mode ie. 400Mhz, and 2GB of RAM, then you are fine even if other areas are showing in error. VISTA is still rather wonky :) Link to comment Share on other sites More sharing options...
emax1ram Posted October 11, 2007 Author Share Posted October 11, 2007 Yes, I have run that program, it also shows 2gb installed and in the correct slots. It shows the correct specs for each mem stick. Yes, this is a very strange problem, vista is a complicated os. Thank you for all your advice.
