Computer is an eMachines D3415
FIC Motherboard No. K8MC51G Version PCB 1.x
Phoenix Award BIOS Version 6.00PG Release NAA19EM
RAM 1-1024MB 400MHz DDR400 PC3200, 184p DIMM, 2.5v, Sync, CL=3
AMD Semprom processor 3400+ 2.01 GHz
Hard Drive Seagate Model ST3160021A Size 160.0 GB
Sound Device Realtek AC'97 Audio
Video Adapter NVIDIA GeForce 6100
Windows XP Home Edition Version 2002 SP2
Running AVG 9.0 Free Antivirus software
The machine has two memory slots and will accomodate a maximum of 2GB according to eMachines documentation.
I recently purchased two 1GB RAM sticks of the above specification from Arch Memory guaranteed to work in this make and model computer to upgrade from the one 512MB stick that came with the system. With both new sticks installed, the machines freezes on boot with the monitor displaying thin vertical colored lines on a black background. I've made as certain as I can that both slots are free of dust and that both sticks are seated securely. Also, the machine boots and runs without any problem with just one stick installed. This is true of either stick installed in either slot. I have run Memtest-86 Version 3.5 on each stick separately (one complete pass) and found no errors.
The person at Arch Memory I talked to suggested updating the BIOS to see if that would solve the problem. There is one update available: NAA24EM. However, both eMachines and FIC (the motherboard maker) do not recommend flashing the BIOS due to the risks involved unless one is certain it will solve the problem. That is not the case at this time.
Also, the System Properties box in Windows XP shows 128MB less RAM than is installed. I assume this 128MB is allocated to MMIO.
What I would like to know is if the problem with booting the system with both RAM sticks installed is due to the BIOS needing the update, the MMIO allocation, a setting in CMOS, or something else?
Any help getting the 2GB working will be appreciated.
