I'm running Windows XP Pro Sp2, my motherboard is a Evga 123-k8-nf47-ax nForce 4 SLI. I have an AMD Athlon 3500+ 64 CPU, I have 2GB of PC3200 ram but I can only get 1GB to work. I have three ram sticks, one is a 1GB PC3200, one is a 512MB PC3200, and the other is also a 512MB PC3200 for a grand total of 2GB. I can only get the 1GB stick to work, my motherboard has four ram slots, slots 1 & 3 are yellow and 2 & 4 are blue. When I try different configurations with the ram sticks the system does a few thing, either it gets to the mobo splash screen and stays there, the system begins to load windows then restarts, or the monitor simply remains black even as the system sounds like it's starting up. There seems to be one or two configurations that will start up windows but when I right click on "My Computer" and go to properties it says I have 1GB and the memturbo program I use also shows me using under 1GB, although I have the CPUZ program and it says I actually do have 2048MB same as 2GB. Is there a special way to place the ram stick, or maybe a bios setting, or even a setting somewhere in Windows. I play a lot of PC games and 1GB doesn't cut it as well as 2GB for most games.
Oh one more thing, the ram sticks should be fine considering I used to use them all together in my older system with an Asus A7N8X-Deluxe with a Athlon XP 2800+ CPU.
But [link=http://www.digital-daily.com/motherboard/asus-a7n8x/index02.htm]they are saying that it has 3 slots [/link]
Does the motherboard support more than 1 GB of RAM? EDIT: I just looked at the motherboard specification that Karanislove has posted. It supports to 3 GB of RAM. But that 2nd RAM module might be malfunctioning. Remove the first RAM module, and put the 2nd in. If the pc won't startup, then that RAM module is malfunctioning.
are the DIMM slots different colours ? DIMM1 & DIMM2 could be 1 colour DIMM3 & DIMM4 could be another colour[ot]as i think you need to fill both slots in each bank, if they are different colours[/ot]
Make sure that you have equal amounts of RAM in both channels. Then, go into BIOS and set the Command Rate (may also be labled 'CPC' or 'Command Per Clock') to 2T. The A64's don't take kindly to dual-channel mode with 3 sticks of RAM. It's do-able, but generally, 3 sticks is the odd-man out and seems to be very tricky to get going.
