Question about ASUS Motherboards

RAM Memory Speed compatibility

I recently successfully installed 2 x 1GB [240 pin 128Mx64] DDR2 PC2-8500, 1066 MHz unbuffered, Crucial supplied memory units. I used the Crucial dianostic tool to select the 2x1GB units which were recommended by Crucial as compatible with my PC's exisiting memory units. The mother board is Asus M2N-TE and has four memory slots, two yellow, two black. There are two original [not Crucial supplied] 500 MB memory units installed [240 pin 128x64] DDR2 PC-5300, 667 MHz unbuffered. All units have been installed as pairs. Please advise if the total memory will run at 667 MHz, i.e. the 1 GB units may not operate at the optimum 1066 MHz of the new units. If the total 3GB memory can only run at 667 MHz would it be best to remove the 500 GB and use the 2GB on its own to get the faster memory speed? I do not use the PC for games but would welcome faster memory for downloads. Also, how do I modify the BIOS settings / system board settings to optimise the relationship between the 2GB faster memory units and the BUS speed?

    shanemorris, Many thanks for your very helpful and prompt reply on memory speed. Have you any information on the second part of the issue, i.e. should I need to change the BIOS settings and System BUS speed to accommodate the faster memory units? If so any advice on how I may do this?

All memory will operate at the slowest speed chip unfortunately. the only way to get the higher speed is to have all chips capeable of that particular speed.

I bought a new 1GB ram(DD2) when i insert it it nt work bt whenever i insert it with old 512MB ram then its work bt in bios setting only show the 1GB ram


Maybe 1GB is the maximum amount of memory that your system will hold. And maybe your system likes memory to be in pairs, so when you put the 1GB in by itself it didn't work, but when you put it in with a 512MB it works.

Your motherboard can take DDR or DDR2 RAM modules.

Crucial says: "Each memory slot can hold DDR PC2700,DDR PC3200,DDR2 PC2-5300 with a maximum of 1GB per slot." No sense getting 4GB since the max is 2GB.

You can get higher speed RAM (PC2-6400) because it is backward compatible.

I would go with the 2 X 1GB Corsair from the ones listed.

Or consider the options on Crucial's site. See this page:

http://www.crucial.com/store/listparts.aspx?model=P5VDC-MX

Two 1GB modules of DDR2 PC2-5300 run about $34 US.

(PS. Your 450W power supply will handle about anything.)

RAM Help!


Hi there.
Yes it is related to PC2 and it runs at 800Mhz, this why your system is seeing only half the speed, your system does however support a module running at 333 module and a 400 module, this is the base limit that the memory runs at.
If the memory was 533 then the computer would not start up because the bios wouldn't recognize it.

Thanks for using FixYa!!
