My wife has an oldish Fujitsu-Siemens Scenic P300 micro tower with a D1761 motherboard and she would like to use Windows 7. Unfortunately it only has 1GB of RAM and, ever the helpful husband, I said I would upgrade it to 2GB to make Windows 7 a bit happier when I installed it. I downloaded the motherboard manual and saw it had 2 184 pin slots so I ordered a couple of 1GB PC2700 unbuffered sticks, which the motherboard manual suggested should work fine. I popped the side off, installed the new momory and cannot get a boot. If I put one of the old 512MB sticks back in, the computer will boot and see it, but not the new 1GB stick. I ran the Crucial system scanner and the memory I have bought, admittedly not from Crucial, should work fine. What is going wrong? I know a little about PCs, having built a couple and repaired a few, but I cannot think what could be the problem here. I would appreciate any advice or thoughts.
The machine hangs up pretty much immediately I power it up. There are no beeps for POST. The strange thing is if I go into the BIOS startup page the memory seems to be registered there, which is fairly odd.
How about using just one 1GB module? Will than work? What if you try one module at a time in each of the slots? I noticed in the manual that the system may complain if the memory is not a Siemens/Fujitsu memory. Also are the modules non-ECC?
If I put a new memory stick in one slot and an old memory stick in another the PC only "sees" the old stick, but boots up fine. It doesn't seem to matter which slots I use for which. The label on the memory does not say whether it is ECC or non-ECC but it does conform to the PC2700 standard, whixh according to the motherboard manual should be fine. However, you could be right about the non-ECC thing, as it is mentioned in the manual. How do I find out if this memory is or isn't as it doesn't say so on the label? I don't want to buy another lot of memory and find that the actual problem is that it isn't Fujitsu-Siemens memory. PS Thanks a lot for your advice, sabashuali.
I was wondering what happens when you only use one new stick, on its own. Not together with an old stick... ECC modules are not commonly used in desktops so, depending on where you bought them from, unless you intended to buy ECC it is unlikely that they are. It happened to me once when I bought a stick on eBay and did not notice it was ECC.... so I suppose it could happen. But to be sure, have a look at the sticker on the modules. It should have a part number. Google the number along with the make of the modules and you should be able to find out. Also, I would check the BIOS to see if anything screems out at you with regards to any settings involving memory. I do not know the BIOS options so cannot comment. I will try and have a look at the manual again...
