cannibalterrori Posted January 20, 2006 Share Posted January 20, 2006 Will TWINXP1024-3200C2 and TWIN2048-3200C2 work on a A8N32-SLI at the same time. Link to comment Share on other sites More sharing options...
FLYBOY611 Posted January 21, 2006 Share Posted January 21, 2006 Check the QVL for a final answer but so long as they are the same speed AND CAS latency the answer should be yes. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 21, 2006 Corsair Employees Share Posted January 21, 2006 NO you should not mix 512 Meg and 1.0 Gig modules. Link to comment Share on other sites More sharing options...
cannibalterrori Posted January 21, 2006 Author Share Posted January 21, 2006 Asus claims that you can have a set of 512mb on one channel and a set of 1024mb ddr on the other. Are they just unsure of their own product? I know from my previous experience that they are not usually correct. Link to comment Share on other sites More sharing options...
RJLeong65 Posted January 21, 2006 Share Posted January 21, 2006 Asus claims that you can have a set of 512mb on one channel and a set of 1024mb ddr on the other. Are they just unsure of their own product? I know from my previous experience that they are not usually correct. Unfortunately, both the 512MB modules and the 1GB modules use completely different IC chips, even if the modules themselves are of the same revision number (all of the 512MB 3200C2 modules are double-sided modules with eight IC chips per side, as are the 1GB 3200C2 modules - and thus, they have different Mbit densities). Hence, I agree with the RAM GUY as for the advice to avoid mixing 512MB and 1GB modules in the same system. And even if you can find 512MB and 1GB modules which use the exact same IC chips as each other, you will find that the 512MB modules are single-sided while the 1GB modules are double-sided, and thus performance will be degraded due to the mixture of single- and double-sided DIMMs (remember, a system with mixed single- and double-sided DIMMs will not perform as well as a system with all single-sided DIMMs or one with only one set of double-sided DIMMs, given the same IC chips). Less likely, the 512's are double-sided - but the 1GB's have 16 chips per side (32 chips total), which will not work at all with modern desktop CPU's.

cannibalterrori Posted January 22, 2006 Author Share Posted January 22, 2006 TWINXP1024-3200C2 and TWINX1024-3200C2, of course each pair on a seperate channel for a total of 2048MB of DDR ram. That should work ok, the latency is the same. Any input would be great. Thank you for the feedback. Link to comment Share on other sites More sharing options...

Four 512MB sticks, in this case, will default your memory clockspeed to 166MHz (DDR333/PC2700) with your system. But you can manually set the memory clockspeed to 200MHz/DDR400/PC3200 - but then, you will have to use a 2T command rate instead of 1T. Link to comment Share on other sites More sharing options...
