Best value for the money

Have a nice day!

Hello, The Motherboard's specifications mention that it uses DDR Ram, while the FSB runs at 400MHz. That means that any kind of DDR memory will work up to the maximum of 2 GB (it has 2 slots, so it's up to the max of 2x1GB DDR sticks).
There's no issue with the speed, actually the faster you can get the better results you will have. Try looking for 1GB DDR 400MHz (preferably two of them, if you want to max out the capacity and since it's kind of cheap to do so).
The one you tried and didn't work, might be due to a faulty RAM module.

Manufacturer Specifications - EPoX EP-4BDA533I Number of Slots:
Slot 1
Slot 2
Each memory slot can hold DDR PC2700,DDR PC3200 with a maximum of 1GB per slot.*
*Not to exceed manufacturer supported memory.

• 184-pin DIMM Banking: 2 (2 banks of 1)
• Chipset: Intel 845D
• Error Detection Support: ECC and non-ECC
• Graphics Support: AGP 4X
• Max Component Density: 512Mb
• Max Unbuffered DDR SDRAM: 2048MB
• Module Types Supported: Unbuffered only
• Supported DRAM Types: DDR SDRAM only
• USB Support: 1.x Compliant

Q: What memory goes into my computer, and will a faster speed be backward-compatible?
A: DDR memory with support for DDR PC2700,DDR PC3200 speeds.
Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds.
Q: How much memory can my computer handle?
A: 2048MB.
Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.
Q: Do I have to install matching pairs?
A: No.
No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance.
Q: Does my computer support dual-channel memory?
A: No.
Your system does not support dual channel.
Q: Does my computer support ECC memory?
A: Yes.
Your system supports ECC. You can put non-ECC modules into an ECC system, but be sure not to mix ECC and non-ECC modules within a system. Install the same type of modules that are already in your system.

Care to read this link;

Hope it answers your questions.

From the manual:

2 x 184 pin DDR DIMM Sockets support up to maximum 2 GB unbuffered PC 2700/2100/1600 non-ECC DDR SDRAM memory.

So, to answer your question, for your particular motherboard, no. However, to dispute the other poster, Dual channel is better than regular DDR. It's just your motherboard does not support it.

Max Supported RAM is 3 GB Memory Type DDR SDRAM Supported RAM Speeds 400 MHz · 266 MHz · 333 MHzNumber of Memory Slots 3 x 184 Pin DIMMs

yes, I beleive you can...

The board supports upto 4 GB RAM. PC3200 RAM is supported.

1. Reset CMOS settings by CMOS jumper.

2. Try updating BIOS of your motherboard from :

Does the CPU fan spin when you press the switch? If it doesnt, short the green wire from the power supply with the black one, If the fan still does not spin, the power supply is bad. If it does, the mother board has a problem.

Please get back after this test.
