Re: DDR slots gone crazy-switched to SDR-OK

If you know how to get into BIOS; restore BIOS to factory defaults and try the DDR RAM again.

1GB PC400 RAM does not work with motherboard A7S266-VM/U2

Hello the home page is here:

If any drivers or manual needed select first your windows.
Click on global for download.
Unzip the file and you need a pdf reader (adobe) to read the content.

Here are some specification about you mainboard:

2 x DDR DIMM Sockets
Max.2GB unbuffered PC2100/PC1600 non-ECC SDRAM Memory
2 x SDR DIMM Sockets
Max.2GB unbuffered PC133/PC100 non-ECC SDRAM Memory

(Note: DDR ram and SD ram memory can not be used on A7S266-VM/U2 simultaneously)

This means you can`t use SD RAM together with DDR ram.

The bios could have a setting for this because of the use of 2 different ram types.

Try downloading the manual.

Good luck

My older motherboard has slots for both SDR and DDR ram.I've removed the 256 SDR and replaced with 1 GB DRR, but I'm getting 3 beeps.Perhaps jumpers need to be changed ? What do they look like and where...

Most motherboards no longer have any jumpers for memory, it's auto-detected. Most likely your motherboard doesn't support the size modules you've installed, or you've used an incompatible type. You should check the board manual (usually available from the manufacturer's website) for memory specifications, and be sure yours will work.

I have intel 845 glly desktop board with 256 mb SDR. When I added 128 mb SDR in the second slot it is not recognising it. How to add 128 mb SDR with 256 mb SDR. When I fix 128 mb ram in first slot and...

1st try to exchange the cards in the slot.
2nd try another card
3rd ur RAM slot may not be ok
4th ur RAMs may not be compatible
5th ur new RAM card may not be ok
use same type of RAMs, and same size...
if u have 256, add 256
if u ahve 128 add 128
if u have SDR then dont add DDR
getting compatibility is little difficult...
some times no combinations can work... keeps a old RAM card that was bought years ago may not be compatible with a new RAM card....
even i got all my old RAM cards(256+128) removed and got 2 - 512mb of the same type fixed...even i had issues with my RAMs for 6 months...

Ram compatabilty for k7s5a motherboardand can I run a 1gig of ram with this board

A really unique MB since Each DIMM slot can accommodate DIMMs up to 512 MB in size, although both DDR and SD-RAM are supported, but any one at time, i.e. one among consisting of a bank of 2 DIMM slots(blue pair & black pair having the pairs 2 slots each) for DDR or 2 DIMM slots for DDR or SDR memory cannot be used at the same time. Thus the board supports either 1 GB of PC133 SDRAM, or 1 GB of DDR sdRAM, but not both at the same time.

I hope you got the Catch 22 here !! Nice low costs for doing simple work?
but it's a Catch 22 situation{either choose the Devil or Hell !) ................. sodeep

Ddr ram sdr ram i am same time input that tw0 thats not show two ram capacities just show one ram'' asus p4s533 model please help me

Hi safran0785,
The Asus motherboard, P4S533-MX can run two different types of memory.
(Just not at the same time & in different slots).
You can use 2, 184-pin memory, PC2700/PC2100 MHz or PC1600 up to 2GB. (1GB DIMMs) inserted in the two memory slots closest to the CPU.
Or you can run SDR memory, 168-pin PC133 or PC100MHz DIMMs up to 1GB of memory in the last two slots farthest from the CPU.
You can not run both types of memory at the same time.

The 184-pin DDR PC2700MHz memory is much faster then SDR memory.
The maximum amount of system memory supported is 2GB.

Need more information/questions, just post here.
Good luck safran0785!

Want to up grade to 2g ddr mem


is this your board?

well, if this is your board, you can upgrade your ram to 2gb howerver since it is a dual ram...(SDRAM and DDR) you cant use all the slots at 1 time since they are of different frequencies.

you can use DDr266 (pc2100) as your RAM since this board is a socket A as it is said here in the boards specs.

hope this helps
