Twin 6400 to 6400C4


Recommended Posts



So I just bought this new PC, got it up and running fine, and i run CPU-Z just for the hell of it.


Turns out, they installed 'TWIN2X2048-6400' instead of the 6400C4 that i paid for. :sigh!:


so, I send them an email saying that they got the modules wrong. Guy calls me today saying they can either mail me the C4 modules, or refund the $$ difference.


He says that because they tested my computer for the 6400 timings, it may not be stable with the 6400C4.




Something is telling me that it shouldn't matter? but I thought i'd check here before I replace the modules without testing/modifying things and ruin my machine.



Here are my specs:


Asus P5N32-E SLI Plus

Twin 2048 6400

Intel E6400

900W Tagan PSU

8800 GTX



So if i get the C4 Modules, any bios options that need to be changed? any tests etc?




Thanks much!

SDRAM RAS to CAS Delay (tRCD): 4T

SDRAM Row Precharge (tRP): 4T

SDRAM Active to Precharge Delay (tRAS): 12T
