Twelve_Tribes Posted April 17, 2007 Share Posted April 17, 2007 Hi, first i have to say sorry for my bad english, Iam from germany. :): I got a pair of TWINX CMX512-3200C2 | XMS3202v1.5 | 0523107-1 | XMS3200 512MB 400MHz CL2 Memory. My Computer: Asus A7N8X-E Deluxe, AMD XP-M (DTR) 2800+, PSU LC Power Silent Giant 550W Green Power, Asus 6800GT with 128MB, Two Maxtor 250GB HDDs Raid 0 I have problems with the RAM. I read a lot threads here and try everything to fix it. Nothing helpes. The PC dont run at 200MHz FSB with both modules, i get a lot of errors in Memtest (newest - 1.7?) and Windows crashes, bluescreens, game crashes. Just one modules at 200MHz works. Only both togehter crashes if Dual- or Single Channel makes no sense. I clear CMOS, load default settings, set timings to 2.5 3 3 6 with 2,7V and all the other tips posted in this forum, nothing helps. I try different RAM slots... WTF... :laughing: At 133MHz and 166Mhz is stable also in DC Modus. What can I do to solve this problem? I suggest that is not working anymore and this is just a case of incompatibelty, what do u mean? Greetz, Twelve_Tribes Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 18, 2007 Corsair Employees Share Posted April 18, 2007 And I am sorry it will not unless you have a 200 FSB CPU, and the CPU you have listed will run at 133 MHz by default. Link to comment Share on other sites More sharing options...
RJLeong65 Posted April 19, 2007 Share Posted April 19, 2007 The RAM GUY is correct. With an AMD Socket A platform, especially one which is based on a motherboard using an nForce2 chipset, you should not run any memory faster than the CPU's actual Front Side Bus (FSB) clock speed without risking major stability issues. And even if the higher-clocked memory runs stably, you'll gain practically nothing over running the memory synchronously with the actual FSB speed (in terms of overall performance) since the maximum bandwidth of single-channel synchronous memory is equal to that of the processor's FSB - in other words, single-channel PC2100 memory has a bandwidth equal to that of the FSB of most Athlon XP processors. Attempting a faster memory speed and/or dual-channel will result in the processor's FSB itself becoming the limiting factor. Thus, since that XP-M runs its FSB at 133MHz by default, you should also manually set the memory to run at 133MHz (DDR266/PC2100) for best results.
