Problem with CMX512-3200LLPT


Recommended Posts

I purchased this RAM (TwinX1024-3200LLPT) from Newegg and have been running it in my machine for a little over 2 years now. Lately I've noticed that my machine has been running games and apps at very sluggish speeds. My main problem is that when I'm trying to install certain apps or programs I'll run into some problems related to my RAM. Such as when I'm installing windows sometimes I may not be getting a 100% clean copy. I thought it could've been a HD or mobo problem, but when I'm running games such as World of Warcraft I constantly get memory read errors. Further more I can't even install World of Warcraft because it keeps on claiming files on the DVD/CD are corrupted; this is correlated to my bad RAM. I've tried switching HD's and that did not work. About 3 weeks ago I tried my cousin's newly purchased RAM (XXXXXXXXX 512mbx2) in my computer and it worked like a charm. I tried installing World of Warcraft and had 0 errors, and my game ran as smooth as ever, again with no errors. I've concluded that it's definitely my RAM that's causing me issues. Currently I'm running my PC with only one of the 512mb sticks and it seems to run the game fine, but it's very sluggish and my machine cannot multi-task. If I run more than one program it starts to slow down to unbearable speeds. Please help me if you have any info, thanks.

What's the speed of the other memory?


What is the FSB of your CPU?


Test one stick at a time in each slot using Memtest86+ and the following settings:


Memory speed must match CPU FSB.

CAS Latency (tCL): 2

RAS to CAS Delay (tRCD): 3

Row Precharge (tRP): 2

Active to Precharge Delay (tRAS): 6


Memory Voltage: 2.75 Volts

All other settings to defaults.

The memory that I tested in my machine had the exact same timing (2-3-2-6) as the Corsair RAM that I have.


If you looked at my PC spec's you'd notice that I'm running an AMD Athlon XP 3000+ which has a FSB speed of 400mhz.


Unfortunately I am not with that machine until the weekend so I cannot run Memtest until that time. I don't doubt that at least one of my sticks has decreased in performance greatly. I'm not sure why the speed of my FSB would dramatically decrease the performance of my RAM at this time. If my RAM were to be acting like this since I bought it, then it would make more sense. If you could explain to me why you think my RAM would dramatically decrease in performance overtime because of my computer specs instead of just performing poorly right of the bat that would be great. Thanks.

Please set the memory voltage to 2.7 Volts and test them one at a time with http://www.memtest.org to be sure one is not failing. If you get errors please follow the link in my signature and we will be happy to replace them. However, if you get errors with both modules that might suggest some other problem; and I would test them in another system if you can to be sure.
