Corsair TWINX1024-3200C2 + TWINX1024-3200XL

Hello.

I have just bought additional RAM for my PC. It is a pair of 512MB modules (TWINX1024-3200C2). These are working now together with a TWINX1024-3200XL pair. They should work @200MHz each as specified. But when I use CPU-Z v1.21 it states the memory speed is only 134MHz.

 

My motherboard is an ASUS A8N-SLI Premium (BIOS V.1009) with AMD X64 3800+ Venice CPU. I know these pairs of memory modules have different timings. Do you recommend using this configuration? If yes, which timings should I use (BIOS settings possible only for all of the 4 modules together)?

I wanted to have the best performance with two matched pairs of 3200XL, but the first pair is now 1,5 years old and I think I wouldn't get the same revision again. I chose the 3200C2 pair because of the lower price.

Actually, the 3200XL is no longer in production -- the IC chips used in the 3200XL's are no longer being made. And because you're mixing different SPD's and different IC's, your system defaulted to DDR266 in order to ensure stable operation. And even if you can find four matching 3200XL modules (remember, all 3200XL's use the same IC chips -- the revisions are based on the different circuit boards used), it is fairly likely that you'll have to use a DDR333 speed and/or looser-than-rated timings in order to run stably due to the increased loading on the memory controller. Therefore, it would be best to completely replace whatever you have right now with a TWINX2048-3200C2 or a TWINX2048-3500LL kit for best performance.
