The Intel Q9650 arrived and its performance is well worth the price.
I tried the SOCHOX 8GB DDR2 PC2-6400 800Mhz DIMM AMD RAM and it still
won't boot. The MOBO can't handle it, I guess.

Great CPU. I've been running a Q[X]9650 for the best part of a decade now
and it's still doing everything that I ask of it and rarely runs above 50%
CPU usage, even when gaming.

Thanks.

In an effort to exploit 4GB PC2-5300 compliant RAM, I purchased a 200 pin
laptop memory module for $31 and a JET-54021 200-240 pin adapter. The RAM
was tested by the vendor. I used memtest-86, Windows Memtest and the memtest
app to test it. It passed all tests even after dozens of iterations.
However, the PC had a tendency to crash. I had placed the adapter and RAM in
the slot closest to the CPU. When I moved it to the slot further from the
CPU, it crashed immediately. I conclude that the longer signal path made it
more unstable.

This observation may the interest to users contemplating the same idea.

4GB 240-pin PC2-5300 compliant RAM is available but it cost USD$200. I plan
to wait for prices to drop. Why? I want 8GB memory without the trouble of
upgrading my MOBO.


Pricing on memory isn't always rational.

You have to get out your pencil, and do a few
calcs, to see if there's a different way to upgrade
for less money.

Using a DIMM adapter could throw off signal integrity.
So that's one unknown. You certainly wouldn't want to
use four adapters on a four slot motherboard like that.
Try one adapter per channel and put it in the slot
furthest from the CPU or chipset.

And there is actually a DRAM timing parameter which
compensates for the length of the DRAM bus. I doubt
your adapter threw off the dimensions too much, but
I just thought I'd mention that such a thing exists.

Normally, nobody even thinks about adjusting that
timing parameter in the BIOS, because it's considered
to be a "manifest constant of motherboard design". The
motherboard designer tells the BIOS designer what value
to use, and there's no incentive to change it.

Thanks for the info. Luckilly I bought a mobo (10 years ago now!) that could
take 8GB of RAM. Unfortunately I've been using 8GB for about 7 years now and
wish I could have more. It's really the only thing holding back my 10 year
old machine in any appreciable way. Sure it'd be nice to have a faster SATA
bus or PCI specification but the only thing that's really bothering me right
now is the RAM limit.

Oh and Firefox. When I'm gaming my PC uses about 50% of it's RAM for OS and
game (Path of Exile) and plays very well. If I leave Firefox open while
gaming that jumps tp 90% of RAM and the thing starts paging. Even with an
SSD fitted that makes gameplay stuttery.
