memory confusion

Specs: Windows XP, P4 3.0 GHz 2.0gb
I recently upgrade my memory from 512mb to 2gb (mb P4M800). From the windows System Information program I get the following info:

Total Physical Memory 512.00mb
Available Physical Memory 509.87mb
Total Virtual Memory 2.00 gb
Available Virtual Memory 1.96 gb
My questions are: Am I getting the full benefit from the new memory and what is the physical memory referring to.

Thanks for your time.

"Total Physical Memory 512.00mb"

Look like only 512MB is being recognized.

Right click on My Computer, then click Properties...how much RAM does it show under Computer:

Your system doesn't seem to be seeing the new RAM. The new RAM may not be compatible with your motherboard.

Don't confuse virtual memory with physical memory.

Go to crucial.com and use their online scanner to determine what memory you can use.

I suggest you remove the added RAM prior to performing the scan.

Writ down the actual module numbers crucial recommends and post here. Also post the numbers from the label on the new RAM.

My computer shows 1.00 gb of mem.

OtheHill
I ran the crucial scanner with the memory in it said it encountered some errors but listed only 512mb in one slot and a maximum capacity of 1gb. The manual for the mb says each slot will hold 1gb for a maximum of 2gb.The memory I put in was 184 pin ddr sdram ddr 400(pc3200) dual channel kit from ozc model ozc4002048eldcpe-k. Just a note SIW sees both channels of memory but lists the mb maximum at 1gb. Could the "dual channel" account for this.

What does Crucial show as compatible RAM?

Just to confirm that I looked at the right motherboard, do you have a Biostar P4M800-M7? Because there are several other boards that use the VIA P4M800 chipset. ECS actually uses the same model number (P4M800-M7)...it *may* be the same board.

Biostar lists the max RAM as 2GB:

Buying dual channel RAM can be confusing. You may have only bought 1GB (2x512MB).

Jennifer the crucial scanner said it couldn't get enough info to make a recommendation.

Jam--I don't know if it's biostar or not but its model number is P4M800CE-8237

OtheHill SIW reads two slots each with 1gb of memory

That particular RAM calls for increased voltage. Maybe it isn't fully compatible. Look at the link below at newegg.com. Has a rebate on it too. Look at the specs.

OtheHill -- that's the memory> I'm not familiar with the voltage requirements-can I check that in some fashion

OtheHill : The only voltage reading I can find is when the computer lists the "dram voltage as 2.59 while it's posting. Is this the voltage referred to in the specs you referred me to?

The specifications on the newegg.com link I posted. It states that RAM wants 2.6-2.8V.

Your board is probably set for 2.5V.
