Hello
The motherboard supports DDR3 1333/1066/800 MHz or DDR2 memory 1066/800/667 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The dual-channel DDR3/DDR2 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidths of up to 19.2 GB/s.
DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel
2 x DIMM, Max. 8 GB, DDR3 1333/1066/800 Non-ECC,Un-buffered Memory 4 x DIMM, max. 16GB, DDR2 1066 / 800 / 667 MHz, Non-ECC, Un-buffered memory Dual channel memory architecture When installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel. Ensure to install the DDR2 1066MHz DIMMs ONLY on the BLACK slots! Refer to www.asus.com or this user manual for the Memory QVL(Qualified Vendors Lists). When installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.
Hope this helps

If its one RAM den be sure it is 2 GB if 2 RAMS den please see that have you fixed the RAM properly..Try taking out the RAM and clean the lower portion with a clean Rubber/Eraser and dne fix it back properly..

did u check the old RAM...do they also show only half ?
may be ur new RAMs are not compatible with ur MB
what's the speed of ur new RAMs....400 or 533 ?

I don't think a difference of 133MHz of memory speed will make a difference in your gaming performance either way. Also, you won't be able to use more than 3.5GB of memory if you don't have a 64-bit operating system. Finally, it'll be a rare person who actually notices a difference in using 8GB vs 4GB of RAM. So, in conclusion, just buy 4GB of 800MHz RAM and spend your money and your time on a good graphics card, if gaming performance is your main concern. If you have any further questions, contact me through http://www.inovagent.com.

insteading of changing the motherbard for making it fast try upgrading the memory cards it add extra memory stcks in the computer to make it faster...

DDR2 800 MHz (PC2 6400)

the best

and 2gb or 4gb is up to you

This website is the details of your motherboard from intel site you can have look in to that the processor 3.2 ghz is supported but L2 cache must be 512 kb only(you are trying with 1mb one it is not supported) your processor doesnt suits the motherboard specification as i have told it previously ..

here are list & details of supported processors below:

intel® Pentium® 4























3.40 GHz 800 MHz 512 KB P20 or greater All board revisions support these processors. 3.20 GHz 800 MHz 512 KB P06 or greater 3 GHz 800 MHz 512 KB P05 or greater 3.06 GHz 533 MHz 512 KB P02 or greater 2.80C GHz 800 MHz 512 KB P05 or greater 2.80 GHz 533 MHz 512 KB P02 or greater 2.66 GHz 533 MHz 512 KB P02 or greater 2.60C GHz 800 MHz 512 KB P05 or greater 2.53 GHz 533 MHz 512 KB P02 or greater 2.40C GHz 800 MHz 512 KB P05 or greater 2.40B GHz 533 MHz 512 KB P02 or greater 2.26 GHz 533 MHz 512 KB P02 or greater

so just try changing this processor to 512 kb L2 cache processor ..........


any doubts you can reply me
i am always here to assist you
thank you
bye
rate my solution

What version is your board. PC Chips P23G V1.0 up to V3.0 ?
