Help with upgrading RAM

I have an A8N-SLI Deluxe motherboard. I had bought a computer with that motherboard, and it had GEIL 512x2 DDR-SDRAM ( http://www.geilusa.com/proddetail.asp?linenumber=19 ).

I bought Corsair ValueSelect 512x2 RAM ( http://www.walmart.com/catalog/product.gsp?product_id=3650495 ).

The motherboard site says both those RAMs are supported. I plugged the new RAM into the 2nd and 4th slots (the only ones that were open), but when I started the PC they didn't work. I still only had 1 gig of ram, even though I could see all the details about it in SiSoft Sandra's mainboard information.

Since then I tried putting them in every position possible, and I can't get 2 gigs. Can I even do it or do they not work together?

I need help, thanks a lot.
 
that motherboard supports up to 4 gigs of ram. try every stick of ram by itself to make sure you dont have faulty ram.
 
Hmmm

I think we are facing a different issue here. I suppose you are using a non-Venice core Athlon64. As a result, it is not possible to run 4 full slots of memory at the full 400Mhz. It's a known limitation of the older Athlon64s. You may want to try and lower the frequency of ram to lets say 333Mhz and then add the extra 2 memory sticks. I hope that this will solve your issue. You may need to go even lower with the frequency in order to get them to work properly.

JAN :D
 
thia could also be caused by the two types of ram using different voltage settings, you could try bumping up the voltages to see if that makes a difference
 
Thanks for the suggestions. I don't know how old the A8N-SLI Deluxe is though. It doesn't say anything about limitations in the manual.

The site says : Memory - 4 x 184-pin DIMM Sockets support max. 4GB DDR400/DDR333/DDR266 ECC/ non-ECC un-buffered DDR SDRAM memory
- Dual Channel Memory Architecture

Also, how do I change the voltages?

i dont know much about this board but i would imagine there's a section in the bios where you can adjust the voltages... have look at the manual and see what it says
