On right of page choose whether you are using 32bit or 64bit OS.

The above link will get you FREE software that should recognize what RAM is installed.
Good utility to have on hand for future reference.

It might help you sort things out.
Good luck.

Thanks Mike I am using a 128 bit operating system.
No, I don't think so. Currently your only choices are x86(32-bit) or x64(64-bit).

According to Dell they have 4GB DDR-2 for the OP's system. The specs of the new ram looks correct but is either defective or not compatible for some reason.

Sorry Bobtran but the questionioner has not read the thread. I have provided extensive information which I would hope that anyone using this forum would read. Or am I missing something?

Fine.....you have the correct memory and a 128 bit os..cool.

Remember that when dell wrote the specs for this computer that DDR-3 memory was not available and DDR-2 was state of the art. Dell expected Memory manufacturers to produce desktop memory in 4gb amounts...instead manufacturers went to DDR-3. If you take a little time to check out specs on current computers you will find numerous references to 16gb max memory with 2 slots requiring 8gb sticks which are not currently available. Thus the manufacturer is anticipating a technological item that may or may not become a reality.
But the memory I have is 4GB DDR2 or is it?

DELL 8 GB (2 x 4 GB) Dell Certified Replacement Memory Module Kit for Dell Precision WorkStation 490 : Computer Components | Dell


Jim
Hi since Dell have not responded via their forum so far who knows. I still have not got back to my supplier, but does anyone really think he is wrong? Perhaps what I was supplied is incorrect, now that is possible. Anyway, he hasn't a lot of this memory to sell and according to a local TV engineer this memory etc or rather all chips are virtually immortal! Hardware? One heatsink fan failure, due to a broken clip, on a Dell cost less than 2 GBP over almost 25 years of PC ownership and replacing a backlight on a laptop. My AMSTRAD 386 was taken to the recycling centre just because it was outdated - I needed a CD drive, there was no other reason. I bet my stored 128 k Sinclair Spectrum will work once plugged in! I think nearly all problems are 99.99 per cent software based. I have had no memory failure at all with all the PCs I have bought which amounts about 20 Dell products. My oldest Dell is 2001 and I did add to its memory and replaced the hard drives as a precautionary measure. Incidentally, I bought the replacement spares using eBay.

I suppose that the other manufacturers can submit similar reports, and why not, but then they want to sell new computers so they won't promote the life of their machines, especially as the user might damage them. I might be doing high def video editing so maybe the Dell 490 will not be up to that. Anyway my trusty 2001 Dell Dimension 8200 will continue to serve email and just about everything else leaving the 490 for the heavier stuff.

The above is from your first post. Now you say you have a 128-bit OS. There is no desktop 128-bit.

Guys, we can beat him with a stick later about the whole 128 bit thing later...

Geoff:

It LOOKS like it is the correct memory, but I am still on the ropes on that one. It either isn't the full spec one, or it is defective. At this time, can't help you much further without something similar to test.

Thanks Keiichi25

I have returned the memory after contacting the seller. He found that one of the sticks was defective and he has sent me replacements. The 490 now shows all installed memory.

It is a surprise that if a PC has a defective stick the info that is given about the memory is so odd. I would have thought a more easily interpretated message would be displayed.

Thanks for all the help from you guys
