| RAM not showing up as full amount
I've installed one 128MB chip in computer A, but it is only recognised as being 64MB. I tried it in computer B to find that it was seen as the whole 128MB. So I tried the 256MB chip from computer B, in computer A. It was reported as being the 256MB that it should be.
I checked both chips out, and found that the 128MB had four black box things on the side of it. The 256MB chip had eight on each side. Four times the black boxes, yet only twice the MB. Is this the problem with the 128MB only showing up as 64MB? |

You're probably SOL. Tried the "funny" mem stick in a different slot? Sounds like it has a configuration that your mobo cannot "see". You might be able to mess w/your BIOS mem settings, save those settings, then install the funny stick & see what happens. This would only be for an advanced user, tho.

is it only recognized that way in the OS, or the BIOS?
Did you try just that stick in the mem slot? Different mem slot?
Swap slots with original mem, so you could tell if it is the slot, or the mem stick itself having the problem?

It sounds like your 128Mb stick is "high density" RAM, and the 256Mb stick is "low density". That's why there are 8 chips on each side of the 256Mb stick, and only 4 chips total on the 128Mb stick.
Cheaper RAM sticks are usually of the high density variety, older (and some newer) motherboards won't recognize the full size of the module because of this. They usually show 50% of the RAM, if they recognize it at all.
What are the brand names on the RAM sticks?

God info Quasi. I always wondered about the high-low difference.

I read about high and low density in another thread, that's what got me onto the idea.
The RAM was just listed as being oem, and I can't see any names on it.
The memory slots are okay. The previous RAM had no problems, and neither did the 256MB chip, in either slot. The 128MB stick had no problems in computer B. Computer A is an old computer and computer B is a new one. I tried the 128MB stick with another old computer, it had the same problem. | |

Relaxing memory settings in the bios may get it going. Just another reason to not buy generic ram.
