gte449i Posted October 15, 2007 Author Share Posted October 15, 2007 Hello, I have a memory module that seems to run slow. I have multiple systems with the following configuration that I use for computational modeling: ASUS A8N-VM motherboard AMD Athlon X2 4200+ CORSAIR ValueSelect 2GB (2 x 1GB) VS1GB400C3 Jobs run on a single one of these identical machines run slower than on the rest. Swapping out components, we have found that one particular memory module causes this slowdown. One difference we have noticed between this bad module and all of the good modules is that, in memtest, the L2 cache speed for the slow module is reported as 4316 MB/s, whereas it is reported as 4501 MB/s for the good modules. Do we just have a bad module? If so, can we have it replaced? Thank you, David Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 The L2 cache would be dependent on the CPU, how much does it fluctuate with different modules? And does it fluctuate with the same modules when you run the test more than once? Link to comment Share on other sites More sharing options...
gte449i Posted October 16, 2007 Author Share Posted October 16, 2007 We tested 4 different modules, one at a time, using the same motherboard and CPU. All of the 'good' modules actually gave the same result when tested repeatedly (exactly 4501 MB/s). The one 'bad' module gave the same result twice (exactly 4316 MB/s). We checked this using memtest only after repeatedly testing the speed of the system by running the modeling software that the system is used for. These tests showed that any time that the 'bad' module was present in a system, the system would slow down. Simulations on systems with the bad module ran as much as 25% slower.

Corsair Employees RAM GUY Posted October 16, 2007 Corsair Employees Share Posted October 16, 2007 Let's get them or it replaced. Please follow the link in my signature “I think I have a bad part! Or “Tech Support Express” and we will be happy to replace them or it, please note that you are posting from the forum! Link to comment Share on other sites More sharing options...
