Ram Problems

I have 3 sticks of DDR, all kingston, 3 diffrent sizes, all same spec (2100 non-ecc)

But Things worn't work:
128 Stick - Works Alone
256 Stick - Works Alone
512 Stick - Works Alone
128+512 - Works, but windows welcome screen never comes up
256+512 - Bad RAM Beep from MB
128+256 - Worked

The thing is, the 256 stick isn't mine and has to leave soon, the 128 and the 512 are what I want together.

As far as I understand, they should work together.

System supports four banks of unbuffered DDR memory and eight banks of registered DDR memory. When using unbuffered DDR, use single-sided modules to populate beyond the first two sockets.

Oh, running XP Pro, *think* I have all the bios updates

What motherboard?
Sounds like maybe increasing the memory voltage .1 or .2 over default might do it or using slower memory timings.

If you are not even o/cing the system adn the memory is crapping out a stick speeds I would RMA it. Also check it in someone elses computer to make sure that its not your MB that is casuing the conflcit.

Its a Abit KG-7 (Non-RAID)

I also have problems with video not initializing during window's restarts (boot ups and mb restarts work.)

I think it might be the motherboard, which is why I'm fixin' to buy another one.

To whomever said rma the ram: The sticks work fine individually

I am going to test all three combos on a Biostar M7VIB

Try using memory slots 1 and 3 instead of 1 and 2.
