Dungeoncrawler Posted April 22, 2004 Share Posted April 22, 2004 My current mem config: Dimm slot 1: 256MB corsairXMS ddr(blue slot) Dimm slot 2: empty(black slot) Dimm slot 3: 256MB corsairXMS ddr(blue slot) Dimm slot 4: empty(black slot) Now my problem: I have a 512MB corsairXMS ddr module I would like to install. Problem is, when I insert it into dimm slots 2 or 4, upon boot, I get a memory read/write test error. The three modules where bought at the same time from newegg.com. I even returned the original, and had a replacement sent, thinking it might be a defective module. Any ideas? My motherboard is the PC4800-E Deluxe ASUS. P4 3.0E 800FSB/Hyperthreading. The 512MB CorsairXMS module number is XMS3200R/CMX512R/3200C2 Thanks for any help... DC/Gary Link to comment Share on other sites More sharing options...
CandyKid Posted April 22, 2004 Share Posted April 22, 2004 Welcome to the forums, Dungeoncrawler! If I'm correct that the model name on your 512Mb module is: [b]CMX512[color=red]R[/color]-3200C2[/b] Then it's not a failing module, it's an incompatable one. The [b][color=red]R[/color][/b] denotes [color=red][b]registered[/b][/color] memory. Although sometimes it works with your board ([i]for some reason, 1 module can...[/i]), it won't work with the other two un-buffered modules you have ([i]I'm guessing the model on the other two is: CMX256A-3200C2[/i]). You really need to run un-buffered, non-registered, non-ECC memory with that mainboard! That is, memory without an [color=red][b]R[/b][/color] or [color=red][b]RE[/b][/color] in the model name. [EDIT]I'd return that module (or eBay it) and get another pair of matched modules.[/EDIT] CAS - 2.5 RAS to CAS Delay - 3 RAS Precharge - 3 Cycle Time (tRAS) - 7 DDR Voltage - 2.7x BTW, if you feel you've got a failing module, run it by itself with [url=www.memtest86.com]Memtest86[/url] ([i]pull the other modules out of the board, that is[/i]).

Corsair Employee RAM GUY Posted April 22, 2004 Corsair Employee Share Posted April 22, 2004 Well actually, with Intel chipset the modules would need to be matching when in dual channel. In other words you can run 2-256 Meg sticks in slots 1-3 and 2-512 Meg sticks in slots 2-4. But you would not be able to mix densities! Link to comment Share on other sites More sharing options...
CandyKid Posted April 22, 2004 Share Posted April 22, 2004 Oops! Sorry! I rescind my ignorant reply! Listen to RAM GUY, he's like a walking memory encyclopedia. PLUR CK Link to comment Share on other sites More sharing options...
Dungeoncrawler Posted April 23, 2004 Author Share Posted April 23, 2004 Okay people...if I have my facts straight, I need to purchase another 512MB module of the same type (R) as described in the previous message, or I need to send/sell the current 512MB module and get a non-registered, non- EEC 512MB module? Just a little confused, but really appreciate the replies. Thanks again. DC/Gary Link to comment Share on other sites More sharing options...
CandyKid Posted April 23, 2004 Share Posted April 23, 2004 Sorry! I think I'm doing more confusing and less helping on this one... You should sell/find another purpose for your registered module and get non-registered, non-ECC modules. If you wanted another 512Mb total (for 1Gb) I'd reccommend the TwinX512-3200C2 pack which is a pair of 256Mb SIMMs (2 x CMX256A-3200C2). Just to drive what RAM GUY said home (into my own head too) you'll need to purchase TWO more modules to keep running in Dual-Channel! They'll need to be the same type and same size to function correctly, which is why I suggested the TwinX pack, it's exactly that. PLUR CK Link to comment Share on other sites More sharing options...
Dungeoncrawler Posted April 23, 2004 Author Share Posted April 23, 2004 dude, don't be crazy... :o: I appeciate any/all replies to questions I post. No one is perfect, and that especially applies to me. It was not that you were confusing me, it was just that I wanted to make sure I was reading both of you correctly. Sorry for the confusion. Hehe, I know what to do now. Going to go the (x2)256MB route I think. I'm just glad I know now what the problem is. I really thought maybe my mobo had a couple of dead dimm slots. Have a nice weekend all. DC/Gary Link to comment Share on other sites More sharing options...
CandyKid Posted April 23, 2004 Share Posted April 23, 2004 Best wishes! BTW, if you wanted to test the DIMM slots, just move your existing two modules into the other pair. PLUR CK Link to comment Share on other sites More sharing options...
