My co-worker is having a problem with his ram. He has DDR. His computer only detects 2 gigs of ram. Any way to get all four to work besides buying 64 bit?

1. First and foremost blow out all the slots thoroughly. Make sure all the connectors on the RAM are clean.

2. Check to make sure the board supports that amount of memory. My old board would support a 2GB stick in each slot, but not 2 2GB sticks. Some boards just have a hard limit.

Does the BIOS detect all the RAM?

1 gig a stick. Only 3 slots.

64bit supports up to 8gb ram and 32 supports up to 4gb

No, from what I remember, 64-bit operating systems can map up to 16 exabytes (thanks Cheetah for the correction) of RAM. We won't be using that much in a few years.

Let me get this straight, in your first post, you said his computer had 4GB of RAM (4x1GB). In your second post, you said it had 3GB of RAM (3x1GB). What's the real amount?

I agree with Cheetah, but I doubt the first solution would help. Sure, dust could be on the DIMMs, but from my experiences, not on the interface/connector itself. My computer used to have tons of dust clogged up in the fans and in the CPU fan (enough for the idle CPU temperatures to increase 20 degrees celsius), but there was never a dust problem with the RAM.

Wrong. 64-bit addressing supports up to 16exabytes of RAM. 32-bit supports 4GB yes, but VRAM is included in that 4GB as well.

why you need ram anyways it doesn't help.. if you got a harddrive that has 200 GB thats already 200 GB more ram if you just set your virtual ram setting to a higher number.. that means it will be using your harddrive as ram..

Sure harddrives used to be bad for ram.. cuz they are slow only like 1 MB per second.. and rams are 1 GB per second. But its not like RAM is that importmant for computer speed..
CPU is most important peice on your computer the faster GHZ you have the better your computer speeds will be.

Dual Cores add up the GHZ's which lets say you have a 2.6 dual core thats

2.6 + 2.6 which is 5.2 ghz

GHZ = billion per second refresh in hertz.

so 5.2 = 5,200,000,000 cycles per second.


500 ghz (fastest computer in the world) by IBM
does 500,000,000,000 (500 billion) cycles per second

when you calculate that much information per second why do you even need so much ram if your game is running slow its not because of the graphics takin up too much memory (RAM), It's because its too much stress on the computer to keep up with the processing of the CPU. But in some cases the video card also had RAM for video if you got a bad video card that ends up to bad gameplay as well.

You have no idea what you're talking about, and it shows.

-RAM is very important, and CPU speeds are so high these days they're negligible.

-Virtual RAM is terrible and should NEVER be used unless absolutely necessary. Besides being horrendously slow, it will put a lot of necessary stress on the hard drive.

-You can't add CPU speeds up like that. A 2.6GHz dual core is still 2.6GHz. The clock frequency refers to how fast the transistors physically switch. No matter how many cores or transistors there are, they still switch at 2.6GHz. Clock frequency is not a measure of performance, it simply measures transistor switching rate and nothing more.

Uh no, you have no idea what you are talking about.

You are insanely wrong, it doesn't add like that. It's not just cycles, what it can do with one cycle. Maybe it takes 8 cycles to do a certain instruction, but later on, a newer architecture does it in 3.

Well, current 64 bit processors limit the amount that can be accessed, usually to 48bits. It's probably done mainly for die savings among other things.

Anything that needs to be mapped into memory will cut into your 4gb. With PAE enabled, you should be able to get up to 64gb visible, but Windows limits it to 4gb either way. There's probably PAE enabled linux kernels around somewhere that can do it however.
