Twin 6400 to 6400C4

Okay,

 

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!
