Quick and dirty
CPU P4
Real Clock 200
Effective Clock 800
Memory 512 + 512 DDR2 PC2-3200

Now comes the hard part (at least for me).

What is the highest DDR2 memory that is supported on this computer?
Will DDR2 PC2-5300 run at the PC2-5300 speed if I remove the PC2-3200 memory?
THESE MHZ AND MHZ AND (MHZ) HAVE ME ALL CONFUSED.
I bought the 5300 memory on sale (2 - 1meg sticks of memory)
Would also like to know if better with the 2 - 1meg alone or
added to the 2 - 512 sticks.
My computer supports dual channel.
Thanks, in advance, for any information.
Bob

Hello bpbp00 and welcome to G2G!

Not all P4 motherboards support DDR2, check the specifications of the motherboard.

I already posted that the motherboard uses DDR2 memory. It came with the 2 sticks of 512 DDR2-400. The Everest motherboard site does not tell me what is the max speed memory that I can use. So we know that DDR2 memory is OK. I bought two 1gb chips of DDR2-667. I already know that if I put all 4 sticks in at the same time that I will run my memory at the lowest speed. I need to know the highest speed memory that the motherboard can accept. It is an Asus PTGD1-LA and the specs say Real Clock - 200mhz, Effective Clock - 800mhz and bandwith 6400 MB/s. Would I run better with all 4 sticks of mixed speed or just the two 1 mb chips of the higher speed?
Thanks

I checked the hp site for my computer model a1133w and it says DDR2. Everest says DDR2. The memory sticks I bought and inserted say DDR2.
So, LETS JUST ASSUME that I have DDR2 memory as described previuosly. Should I mix and match and what is the highest I can go.

According to the correct specs is supports 533MHz/400MHz DDR2. Check the Wikipedia link for speeds > http://en.wikipedia....wiki/DDR2_SDRAM

You could also try running Crucial's system scanner, it will automatically detect what you need > http://www.crucial.com/systemscanner/
