Recommended Posts

have installed 2 memory modules xms 3200c2 on slot 1 an 3 and setting manually ram clock to 200 mHz,

now i'm using the modules at 200 mhz( manual selection) and spd auto 3-3-3-8 and system is stable with bios F7 .

i have installed bios f9 or f10 but system recognized only one module.

i have changed modules position but nothing happen.

i have reverted to bios f7 and sistem recognized 1 gb total ram again.

someone can help me.

i would like to use the new one bios without loss of ram.

 

regards

:eek: :eek: :eek: :eek:

I am sorry, but this MB like many that are on the market now, require that the modules, if you use more than one be identicle. And one of the reasons we came out with Twinx sets of modules.

I would try and find another use for the older module that you have and then just get a Twinx1024-3200C2 for best performance.

If that is not an option for you, you can try and RMA both modules, but I would suggest you send an a email with a copy of the form or all of your info name address and phone# and the Module part# and copy the link to this post and email it to Rma@corsairmemory.com; but explain that you need 2 modules that are the same revision.
