Problems with new RAM sticks in two different motherboards.

[zoobooboozoo]

Hi all, I'm having 2 problems with 2 different motherboards and the new memory sticks I got for them. In both cases the old memory stick was fine, but I wanted to get new, faster ones, and also get two sticks for dual channel memory for each motherboard. 1) DFI LanParty BI G41-T33B: When I replace the old stick with the new ones the screen would stay black. No Bipping sound from the motherboards, like it makes when it can't recognize/support a certiain memory stick. everything seems to be fine EXCEPT the screen would stay dark. I tried placing just one of the sticks or the other but nothing helped and the problem remains: with the old stick - everything is fine, new stick(s) - screen is black. 2) ASUS P5KPL-AM: I replaced the old stick with two news. but only 2GB are rcognized. I checked the BIOS(it's not a windows issue, only 2GB are recognized in the BIOS). and in one of the BIOS Setup pages it says something like:"Installed Memory size: 2048 Usable Size: 2048" I'm not sure if it means there's room for 2GB more or that I filled the max capacity... I checked the motherboard model in asus' website and also the CPU-Z report and the capacity should be 4GB as far as I can tell. Thx in advance, ZBBZ.

Your motherboard uses DDR2 memory. Was the new memory DDR3?

https://www.asus.com/Motherboards/P5KPLAM/#specifications, It supports up to 4GB DDR2, So get two lots of this G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-2GBPK - Newegg.com which is 1GB per stick then you will have a total of 4GB and will max the ram out..
