Question about ASUS P5RD2-VM Motherboard

1 Answer

Only recognises 2 gb when max supported is 4gb...

Is there any way to let it recognise more? through bios maybe?
i looked, but as a beginner is very hard to know.

cpuz regognises correct amount but windows doesn't..

the other thing is it is 800 mhz ram, and mobo supports up to 600something? only, but shouldn't affect at all?

my processor is a pentium D 930, not sure if it's important.

thanks in advance :)

    hi, thanks for the reply :D

    well i bought 2x 2gb 800mhz meant to be kingston, (says hynix on chips :P), original had 2 x 1gb 266mhz no idea on brand. no idea on channels either, would be guessing single channel. i only have 2 slots on the board.

    though the pc won't even start up on the 4gb alone. tried on another pc, and is fine (4gb on cpuz, 3gb on windows, but is something to do with memory remap or something)

    so i mixed the 1gb + 2gb but bios only recognises 2gb which i don't get... i think the mobo is fussy about ram. it seems it is locked on 2gb or something.

    cpuz is reading 266 for the 1gb and 400mhz for the 2gb. i've kind of given up trying to fix it on my own, do you think is a software or hardware problem?

    manual says so, but was starting to wonder myself :P all the specs online also say up to 4gb...

    maybe is mobo driver, never knew there was such a thing, i did a quick search just now, didn't find much... bios i updated already and didn't do anything :)

    well, thanks for your time, will probablly be getting a new motherboard soon then!

Is it all the same exact brand of memory, Dual Channel or no ?

You said its 800mhz ram and the mobo supports 600mhz, is it all 800 or 600 mhz or different speeds. Alot of motherboards will kick it down to match the other sticks some might not.

    Are you SURE the motherboard supports 4 gb ? With only two slots on it seems it would only support 2 gb. The ONLY possibility would be to update the motherboards drivers and possibly bios but I doubt that will work. Might be time to upgrade to a new motherboard if you want to use that memory. Hardware problem...

    *Your vote is highly be appreciated. I hope this will help you. Drop me a comment if you still have problems. I will help you.

    I still don't understand why they made it like that makes me sad, I like ASUS usually :P Anyway Upgrades are always fun, never fails they always come out with something new every month.

When i install Bios up date for MSI KT6 Delta MS-6590 to up grade my RAM to 3 GB i have Problem m My PC go to hill too slowly but i have 2400+ CPU ???? how can i solve my problem

Ram need to be installed in pairs. Windows XP only recognizes a max of 4GB ram 3.5 usable. Windows Vista 32bit only recognizes a max of 4GB ram as well as Windows 7 32bit. Vista/7 64bit can recognise a much larger amount of ram. Find out if your operating system is 32 or 64 bit and make sure you are using the right kind of ram for your system.

I need to know which is the part number of the DDR3 bulded iside the Lenovo ThinkPad Edge 15 0301-GQG leptop?

Manufacturer Part: 55Y3706

2 GB (installed) / 4 GB (max) - DDR3 SDRAM - 1066 MHz - PC3-8500 ( 1 x 2 GB )

So you need DDR3 SDRAM at 1066Nhz PC3-8500

If you are running 64bit Software then upgrade to 8GB (2 X 4GB sticks) otherwise your OS may not recognise any more that 2 MB

c0006679.jpg LenovoMemory - 1 GB - SO DIMM 204-pin - DDR3 - 1066 MHz / PC3-8500 - 1.5 V - unbuffered - non-ECC Manufacturer Part: 55Y3706

My cmos does not see 4GB of memory

If you only run a 32 Bit OS it will only recognize 3 GB of RAM. You must have a 64 bit system and OS for it to recognize more than 3 GB of RAM.

Good Luck,

I have a Azza PT-693BTX motherboard and i am trying to upgrade memory. Once installed it only reflect 1/2 of the capacity i.e. 512 mb show as 256 mb. I also have a PIII 748 mhz and would like to upgrade...

This board is now long in the tooth and will only support a max of 512mb in each slot upto a max of 1.5 Gb, however the chipset restriction will only allow it to "see" single sided ram memory, if the memory used has chips on both sides it will only read one side hence half the real memory is recognised. So use single sided 512mb for max memory yield. CPU is socket 370, the fastest made was the 1400 version using 133fsb, which your board supports, not sure if your bios would recognise this chip, however they were discontinued in 2003 so finding one would be difficult!
