Hi,

I would like to ad some RAM-memory to my pc.
Now I have 2 of the 3 slots slots filled with each a 128Mbyte memorycard

"IRL DEM DP133-064163E
PC133-333-520 125MB
0138-2352-0011"

If I want to ad an extra memorycard, do I have to make sure it is exactly the same as the 2 cards already present? Or can I also use a 256MB PC133 memorycard?

Thanks

You should be able to use the 256 MB memory stick, as long as your motherboard supports it, and it is the same speed/voltage as the other memory sticks on the computer.

Dave Kruger,

And how do I know it is the case?
Stands PC133 for the type of memorycard?
And if so, any PC133-card works?

Thanks.

Yes, any PC-133 should work. To findout if your motherboard will support the 256 MB memory module, you would have to look in the manual that came with the system or the motherboard, or get the model number on the motherboard to look it up on line, if I had the number I could check to see if I can findout for sure. I would say likely that it would support a 256 MB PC-133 stick, but without knowing the model for the motherboard, can not say for certain. If after installing the 256 memory, it gives any errors, you might try taking the 256 MB and installing it alone, see if it boots that way, then try adding back in one of the 128 sticks in the other slots, testing again, then trying the next.

I think I've found it in the manual from my systemboard (NB72-SC/SR Rev.A+)

System memory

* Three 168-pin PC SDRAM DIMM sockets
* Supports 3GB system memory
- Use 64 Mbit, 128Mbit, up to 1.5BB using 256Mbit or up to
3GB using 512Mbit technology, PC-100/PC-133 PC SDRAM
DIMM
* Supports ECC function
DIMMs Memory Size
2MBx64/x72 16MB
4MBx64/x72 32MB
8MBx64/x72 64MB
16MBx64/x72 128MB
32Bx64/x72 256MB
64MBx64/x72 512MB

I'm not sure how to understand the second *.
Does it mean:
- 64Mbit en 128Mbit can be used together
- onely 256Mbit can be used together
- onely 512Mbit can be used together?

And how could you get 3GB using 512Mbit cards if you onely have 3 slots?

[Dave Kruger]

It probably was manufactured that they would support up to 1 GB memory modules (likely with a flash update), and the manual only reflected the lower at time of printing memory module support. The wording for the memory information is a bit confusing, what it looks like to me, is it will support 64MB, 128MB, 256MB, and 512 MB PC-133 memory. You can mix them typically, so you do not have to have all 128, 256 or 512, but in order to get the 1.5GB you could do so only by using 3x512MB memory sticks.

Thanks a lot!
