ram upgrade help - system hangs

I'm trying to upgrade my ram from 1Gb to 4Gb by replacing the 2 x
512Mb pc-2100u dimms with 4 x 1Gb pc-3200's but my system will not
boot with the new memory. It powers up and hard drive led glows
steady. There is no beep code and the monitor remains black.

I tried all possible combinations of the new chips - installing one at
a time in dimm slot 0 and all other combinations of multiple dimms. I
put back my original memory and everything is fine.

My motherboard is an Intel D865GBF/D865PERC with a dual core Intel P4
3.0 GHz and 800 MHz system bus. The motherboard documentation clearly
indicates un-buffered DDR400 is supported with 800 MHz system bus for
up to 4Gb (4x1Gb dimms).

I have removed my AGP video card and am using the onboard video to
avoid memory retention issues (as instructed by the motherboard
documentation).

I am now out of ideas of what may be wrong or what to try next.
Can someone please help?

Did you get these from Ebay ?

Can you provide URLs so we can look at what you bought ?
If not, are there part numbers printed on the memory chips ?

If I had to guess, I'd say this is probably some of that "high density" RAM.

Plus, I'll bet it was a lot cheaper than that good low density stuff. I
know--I bit on it too, some time back. Their ads sure are tempting--so
tempting in fact that I overlooked the density-factor. s

Ebay? Gee ... how'd you guess?!

The individual chips are marked "GX4-75".
There seems to be no obvious indication of any manufacturer or part
numbers.

Do you see an Intel chipset in this list ?
This is the so-called "restricted chipset" list, common to those Ebay sales.
Roughly translated, it means "do not buy me" :-)

i fell for the same thing watch out guys
its rather high density memory
that will work with what chipsets they say
as it wont work with any intel chipset no beep codes nothing
beware thats all i have to say
