Help - Need advice purchasing memory

[blackfirefox]

These boards have been awesome with helping me so I am coming back for me, I would like to replace the RAM in my system with better high performance RAM.

HP - Compaq Media Center m7580n Desktop/PC .

Crucial Memory Scan says:
Each memory slot can hold DDR2 PC2-4200,DDR2 PC2-5300 with a maximum of 1GB per slot.*

Does this mean I can not use higher performance, or can someone help explain what I can use, I am upgrading the PSU and Video Card as well.

HD Radeon HD 3850 - http://www.newegg.com/Product/Prod [...] 6814129101
Earthwatts 480W - http://www.newegg.com/Product/Prod [...] 6817371006

Any advice on what to get would be helpful, would like to stay under $200 USD

Thanks

use a utility called "cpuz" to find out what motherboard you have, what revision etc. After that you can go directly to the website with the ram questions in mind.

Your processor is probably the limiting factor with the memory.
You can use faster memory but it will default to a lower speed.
I don't think you can even change the memory timings in a HP, much less overclock.
I think you should stay with the memory you have unless you want more capacity.

If you decide to buy new ram, get whatever is cheapest. The DDR2 800 ram sometimes sells for less than the DDR2 667 or 533. 2GB kits of DDR2 800 sell for $30-50 online.
