falconpunch Posted October 5, 2007 Share Posted October 5, 2007 I just bought a 512mb stick of Corsair ram to go from 1gb to 1.5 (I want to get another for 2gb, but I'm making sure it works first). When I go into the BIOS it says pc2700 (333mhz) for all 3 sticks. I have heard that this may be a problem with my mobo not supporting multiple double-sided sticks, but I'm not sure if there is a way around that. My specs are: HP a1130n system MSI MS-7093 mobo the corsair stick is VS512MB400 Thanks! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 5, 2007 Corsair Employees Share Posted October 5, 2007 Please look up your system on our memory configurator and only use the memory that was suggested for your system and I would not suggest mixing memory, just use our modules for best performance..

JonKrmr Posted October 5, 2007 Share Posted October 5, 2007 The problem is not with your motherboard. Athlon 64 socket 939 cpu's have the memory controller built into the cpu. This would be a limitation of the memory controller in the cpu. The memory controller will automatically slow the memory down to 333MHz and relax the command rate setting when more than two (2) double sided memory modules are installed. The limitation is more pronounced on earlier cpu steppings but is still there even on the newest cpu steppings. There is no way around it unless you install only two (2) memory modules in the mother board. With socket 939 cpu's, it is recommended to install only two (2) memory modules for best system stability and performance. I would recommend you scrap all of your existing memory and purchase a 2 GB matched pair memory kit. Link to comment Share on other sites More sharing options...
falconpunch Posted October 5, 2007 Author Share Posted October 5, 2007 Yeah I already used the memory config thing and that is the stick it told me to use. I think JonKrmr is right- I'll just have to get 2 1gb sticks if I want to up the memory. Another question is: is it even worth upgrading memory on my system? It was only using 1.2gb of ram during maxed H-L 2 with my new (slower 1.5gb) setup. my CPU is Athlon 64 3500+ (2.2ghz) and my GPU is Radeon X1650XT 256mb Thanks again!

Corsair Employees RAM GUY Posted October 5, 2007 Corsair Employees Share Posted October 5, 2007 I would replace the memory you have now for Two one Gig modules for best performance. Link to comment Share on other sites More sharing options...
