Question about ASUS P4S533-MX Motherboard

2 Answers

Upgrading RAM from 512MB to 2 GB

My Pentium 4 with the motherboard mentioned in the title was running too slow with 512 Mb UNB PC2700 CL 2;
So I bought 2 sticks 1 Gb Samsung PC2700 DDR333 6NS CL2.5 to tune up. When I put in 1 GB Windows XP starts up normally; when I put in the second stick, Windows doesn't start at all and gets turning in circles. The board is installed in 2003 and can have a max of 2 Gb.
Should the BIOS be modified and/or updated and how do I do this?

RAM chip sets

It is OK to mix chip (SODIMM) capacities in the 2 slots in your notebook.

The best system performance will be when you have 2 x 512MB but for now if you install 1 x 512MB, you could even leave the old chip in the other slot, it'll be fine.

I am going to upgrade ram to 1 gb. can i use ddr2 1 gb ram to upgrade .motherboard is microstar model ms-6526 ver: 2 . present ram is ddr1 400 MHz, 512 MB

If your computer has two RAM slots on the motherboard, i would recommend trying it. The computer will run on the 512MB stick alone and just not recognise the other stick. And if it works it works.

I have searced for support documentation and came up with none for the original MS-6526

I run my original version MS-6526 on a 512MB PC2300 (DDR1) and a 512MB PC3200 (DDR1) and it runs just fine for games and videos.

Personally I would recommend trying the DDR2 first and if that fails, return the card and get a DDR1 card. They are expensive, but at least they work.

Not recognizing memory.

The Asus P4S800-X MB can use Dual channel DDR memory and single channel memory. The dual channel memory which comes in matching packs. (Normally 2 DIMMS per pack) is the faster memory.
In other words if you are installing, 4- 512MB DIMMS of PC3200 all memory should be matched,
or you're MB may not see all connected DIMM'S.

See page vii in you're manual. If you're running windows XP, Home or Pro edition the bios will show up to 4GB of memory installed but windows XP 32bit will only show 3GB of memory. As mentioned above all 4 of you're 512MB of memory should be dual channel and run at the same speed. You can run both single channel and dual channel but you must follow Table 1 in you're manual. (1-9).
Example; PC3200 400MHz.
Or 4-512MB PC2700 333MHz. See page 1-9 for memory configurations and the QVL list supported.
Check out Asus FAQ's;

This should help you configure the memory.
Good luck!

Acer Aspire T-180 Memory Upgrade question

Hello, You might be able to add 2GB more. 1GB per slot. You need to get the model # off your motherboard and verify what the maximum amount of memory it will support. 1GB per slot would be 4GB total but some Operating systems will only support 3GB. So some might be wasted if that is the case. You would need to use the same memory type. So if existing is PC2-4300, use the same. Hope this helps.
