Upgrading RAM

  Rob_101 20:01 09 Mar 2008

My friend has an old PC which only has 256mb of RAM. He wants to upgrade this and I did the Crucial Motherboard checker thing to see what memory it uses. His PC uses SDRAM PC133. It says that it can only take a maximum of 512mb of RAM! However, it has 4 slots. Is this right that only another 256 can be added? Doesnt seem right to me. '512mb RAM MAXIMUM?????' Other PC specs are: Pentium 4 1.5GHz, 40gb HD, Nvidia Geforce MX Graphics. I dont think its worth upgrading personally, but he wants to!

I always download my motherboard manual, this gives the true info.

I would double check, it may be that it takes 512mb RAM per slot. If so then it would be 4 sticks of 512Mb maximum

Do you know what motherboard it is?

if its old then possibly 512 is the limit

TBH I don't know what motherboard it is. How can I find out? On the crucial memory test it said the motherboard manufacture was TriGem Computer. Ive never heard of them! Heres the results.

Maximum Memory Capacity: 512 MB
Currently Installed Memory: 256 MB
Available Memory Slots: 2
Number of Banks: 3
Dual Channel Support: N.A.
CPU Manufacturer: GenuineIntel
CPU Family: Intel(R) Pentium(R) 4 CPU 1.50GHz Model 1, Stepping 2
CPU Speed: 1495 MHz

Oops, I tell a lie, it has 3 slots, not 4.

From what I can work out, it has 3 slots, one of which is used at the moment with a 256mb stick. There are 2 remaining slots.

I think lotvic may be right. 512mb in each slot, thus making 1.5gb in total. It seems funny if it is only 512mb in total, because that would mean the other 2 slots could only take 128mb sticks!

What do you think? Ahhh... im confused.

PS. your right rossgolf, it is old! lol

for a PC built in about 2001.

Not only that but it may be necessary for the memory to be added in pairs! click here

Run this ~ It should give you more information on the system click here

Thanks for all the replies.

It turns out that it is 512mb maximum per slot, so 1.5gb is the total amount!
