I have a Pentium 4, 2.66Ghz processor with 848P-A7 motherboard. I purchased hynix 2GB DDR400 SDRAM PC3200(2X 1GB RAM KIT) to replace my 512MB DDR. Why does it not work ? Spec Says that it supports DDR400/333/266 Mhz DDr SDRAM

1) Total maximum amount for motherboard is 2GB.

2) There are 2 Ram Memory slots.

3) Maximum amount for EACH ram memory slot is 1GB.

Either DDR Sdram at 266MegaHertz, or 333MHz, or 400MHz.
PC2100, PC2700, and PC3200, respectively.

There is no DDR1 and DDR2 slots, in a manner of speaking.

May be marked on your motherboard that way, but stating it that way on a computer product support website = No.

You're going to make someone think, you don't know what you are talking about.

They may think you are referring to DDR Sdram, and DDR2 Sdram, and they know the motherboard only uses DDR Sdram ram memory.

Suggest state Slot 1 and Slot 2; or DIMM 1 and DIMM 2.

For additional questions please post in a Comment.

For a Chaintech 9BIA motherboard;

Motherboard chipset is an Intel 845,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

http://www.firingsquad.com/hw/168/Chaintech_9BIA/

PC133 (SDR Sdram at 133MegaHertz;

{Single Data Rate. The proper term, not just Sdram.
Double Data Rate Sdram is Sdram.
Double Data Rate 2 Sdram is Sdram.
Double Data Rate 3 Sdram is Sdram.
DDR Sdram, DDR2 Sdram, DDR3 Sdram.

Synchronous Dynamic Random Access Memory )

Low-Density, Unbuffered, Non-ECC, Cas Latency of 3

(Don't get some cr@p off of Ebay.
It's usually high-density, ECC, that was used by old server computers)

WHEW! Unless you just want to run 1GB of ram memory, I would toss that board! (Two 512MB sticks) ->

-> Need two 1GB sticks of SDR Sdram at 133MHz

$400 smakeroos USD!!

Bah! That is just cra-zy!

Maximum TOTAL Amount is 2GigaByte. (2GB)
Maximum Amount for EACH ram memory slot is 1GB.

IF, you only have ONE ram memory module ('Stick'), it goes in Slot 1. (DIMM 1)
That is the ram memory slot closest to the processor socket.
The Processor reads ram memory Slot 1 first.

Consider updating your motherboard bios.

http://www.asrock.com/mb/download.asp?Model=K7VT2&o=BIOS

Also make sure that your memory is correct for this system:


- Max. capacity of system memory: 2GB DDR or 2GB SDRAM
- DDR x 2, DDR266/200 non-ECC, un-buffered memory
- SDRAM x 2, PC133/100 non-ECC, un-buffered memory

Your Intel D845GVSR has,

1. Two ram slots.

2.Maximum Amount of ram is 1GB for EACH ram slot.

3.Maximum TOTAL Amount is 2GB, (1GB in each ram slot)

4.Uses DDR Sdram at 400MHz, (PC3200), OR
DDR Sdram at 533MHz, (PC4200)

This is an example of DDR Sdram at 400MHz, (PC3200),

http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=1354&name=PC3200-DDR-Dual-Channel-Memory&Nav=|c:1352|&Sort=0&Recs=10

(Not advertising for this website. There are many places to buy ram memory)
512MB + 512MB = 1024MB, or also stated as 1GB
1024MB = 1GB

IT supports Maximum 2GB DDR400 RAM.
It mainly depends on the Processor speed.I think 1gb RAM is sufficient for Your Pentium 4 configuration. If you use more than 1Gb.there is no remarkable speed difference between them.So better choice is use 1GB RAM.

MEMORY 2 x 184-pin DDR DIMM socket support up to 2 GB Support DDR400/333/266 DDR SDRAM

Copied above from ECS website so the answer would yes as it supports up to 3.2GB/s transfer rates at DDR400

Hello,

Located here is the actual specifications of your W3052.

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=W%20Series&model=W3052

The DDR means "double data rate", SDRAM is "synchronous dynamic random access memory" and DIMM is for "dual inline memory module". These are the way manufacturers describe the specific speed, type, and packaging of the memory. You need to get the correct combination for your computer in order for it to function properly. The PC2100 is NOT correct, at the very least it will slow your computer down, and possibly will not work at all. You should use PC2700.

If you wish to add another 512MB taking your computer to 1GB total, then you only need 1 module, a 512MB, like the one that came in the computer. Do not purchase a 1GB module expecting it to work properly with the one already there. It probably won't. If you want to max out your computer's memory taking it to 2GB, then you will need to purchase 2 each 1GB modules, and remove the existing 512MB module.

When you go to the computer store, you ask for either "one five-hundred-twelve megabyte, PC2700, DDR, SDRAM DIMM memory module" or "two one-gigabyte, PC2700, DDR, SDRAM DIMM memory modules".

The part numbers from, Kingston, one of the major add-on memory makers are shown here:

512MB = KVR333X64C25/512
1GB = KVR333X64C25/1G

your motherboard uses DDR1 SDRAM PC2100 max. as stated on their website:
http://www.biostar-usa.com/mbdetails.asp?model=u8668+d
you cannont put DDR2, but you can expand up to 2GB

Hope this helps

G-Skill is what I put in all my custom built computers.  Search newegg.com and you will find what youare looking for.  You want PC2700 DDR.

pls check you motherboard manual if it accept that kind of memory because some board cannot accept.
