Compaq 5WV296 desktop running XP pro SP3
3 slots for ram, maximum 256mb each
I had 2 x 256mb sticks and 1 x 128mb stick. Everything worked fine but I wanted to maximize the ram so I replaced the 128mb with a 256mb.
When I installed the Azen ram I immediately got a "164 memory size error". I switched it to a different slot and got the same thing. Then I removed all ram except the Azen stick and the PC did boot and recognized 256 mb of ram. I added another stick of my older ram and it was recognized for a total of 512mb. I can put any 2 sticks in and they are recognized for 512mb. When I add the third stick is when I have the problem. When I add the third stick I get the 164 memory size error again. I have played with different scenarios for the past 2 days trying to get it to work but it just will not. The BIOS recognizes 768mb of ram but Windows only recognizes between 452 and 644mb depending which stick is in which slot. I also ran a Crucial ram scan from their website and they detected 3 sticks of 256mb. Would I be better off with a different brand of ram i.e. Kingston etc? To repeat, the setup with 2 x 256mb and 1 x 128mb worked fine. Any opinions on how to get the full 768mb working? Thanks
