Check your BIOS, see if it's recognizing all your RAM. You might have a few bad blocks on the stick. Check out a program called memtest86:

Cool

Yeah, but you might wanna run memtest on it just to make sure. Other options are passing it to your kernel, but first check to see if it's a bad stick, easiest way first, then move onto harder things

Cool

A memory fry error that would make 6 megs disappear would probably render the stick useless... What's reporting it as 249Mb? Remember, RAM is not perfectly linear, and whatever proggy you have reporting back 249 may be using some funky combination of 1000=1k and 1052=1k

Cheers,

Finegan

I'm not familiar with gkrellm's metric, what does "free" report?

Cheers,

That is curious, its about 4096 shy of where its supposed to be... I'm stumped man, a ram bank can't die without bringing down the rest of the stick in an ugly tailspin... there are some differences between sticks, but that's a lot not accounted for, unless you have a RAM stealing video card? There are so many differences in the RAM market, low density, high density, CAS-2, CAS-2.5, who knows if they're messing about with what they consider 1Mb in the maelstrom of all of these statistics... if it runs right it can't be that big a deal?

Cheers,

Finegan

missing ram?

No i don't think you are missing any ram or have a hardware problem. I bet you have onboard video. yes?

It is using that memory for the onboard video card.

if you have onboard video, the bios allocates some of your system memory as video ram. otherwise, you have NO VIDEO MEMORY. impossible

Actually, you and the other guys may be both right... That didn't make any sense... Okay, You have normal onboard video with its own chunk of memory on the board, but they tend to steal a couple megs of normal RAM for framebuffering, see if that's the case... you can probably adjust it down to 1Mb in BIOS if I'm not on crack here.

Cheers,

FInegan

it reports 249(gkrellm)
video card has 16 mb of memory
so it has its own memory

It's probably the manufacturer that didn't put all of it on the stick. They use all kinds of tricks to save cash nowadays..
Like buying an 80 gigabytes hd just to find out its actually 80 billion bytes, which is 74 and not 80 gig.. I guess they've started doing that on memory too
