Ok. I have XP Pro on a 5GB partition which it shares with what I
class as 'OS-essential" apps such as AV, Acronis, PerfectDisk,
PartitionMagic, Spybot... There's still 1GB free after a year on
this install. I don't have my pagefile in that partition though.

Hmmm, I did that (5GB C:), but that gets small very quickly. That
is/was with swap on C: too, so that then gets moved to D:.

That's odd. My C: is fine at 5GB, even with XP SP3 installed (uninstall 
files located on data partition). It still has ~1GB free despite me having a 
few 3rd party apps/utils installed there (Java, AVG, Acronis, PerfectDisk, 
Nero...).

Programmes is 15GB and is nearly full, I might have to increase it a
bit with PartitionMagic. I have a 2GB FAT32 partition for pagefile
only, at the start of a fast disk. The balance of those disks are
large data partitions and the other disks are one big partition
also. I find that, as I keep multiple backups (Acronis True Image)
of the boot partition and sometimes the Programmes partition keeping
them small is good. (Although Acronis truncates the free space
anyway so I'm not sure that backups would be *that* much larger on
bigger partitions with the same amount of data.)

I don't make too many images; a re-install is done quick enough, and
the only sure way to get a clean machine again. ;)

Heh! I have a heavilly customised interface and it's not that quick to 
reinstall for me. An image is much, much quicker.

I'm waiting on delivery of a 45nm CPU, an E7300 that should arrive
any minute. My E4500 has been running at 3.32GHz for a while now,
time for a new challenge. The E7300 has a 10x multiplier so I'm
hoping that it will run on a 400MHz FSB (1600 in Intel-speak) for
4GHz at sane vcore and temps. <fingers crossed> It's actually quite
a big job as my cooler has a "bolt-thru" kit fitted which means the
mobo has to come out and the case is quite cramped with all the HDDs
and a full-length GFX card, SCSI card, sound card..... Also, I
lapped the E4500 which gave me ~6�C cooler temps so I might have to
fit the E7300 twice. (I don't want to lap it out-of-the-box until
I'm sure it'll at least work!)

Sounds like a nice project. ;) Good luck taking that thing to the
limit!

Well, I'm a bit disappointed with the new CPU. It's only doing 3.6GHz stably 
at sane vcore (<1.4V). I say "only" as the 65nm E4500 was doing 3.32 at 
<1.4V. Still, the slight speed increase coupled with the 50% bigger L2 and 
new instruction-sets must help I suppose. Floating point and integer MIPs 
have gone up to 3750 and 7750 respectively. (~600 increase in each.)

I've got a few completed Astropulse WUs now (and another queued) but still 
none that have been confirmed, all still pending. I see that they only send 
out two copies of each (last I remember it was three of each for vanilla 
SETI WUs?) with one of the WUs I'm waiting on having been sent to a Pentium 
III 1133MHz machine that does 1068 / 1763 MIPs respectively. I could be 
waiting an age for that one to be verified.

Another, that took my machine 34 hours to crunch, has been sent to a Pentium 
Dual core 3.2GHz, 1457 / 2610 MIPs machine. That's about 1/3 the speed of my 
machine so ~100 hours crunch time on that machine? I reported it 8 days ago 
and it's still pending....

Yeah. There's a client for ATI cards no? (I have nVidia too) I can
imagine that running on both CPU and GPU would bump up the power
consumption quite a bit!

Not that i know. I suppose an 8800GTX running at full-bore would be
quite an energy-slurper. ;) No idea how much Seti@Home tasks it
could, in theory, run. I find some snippets here and there, but no
client yet. We'll see if I can harness the power of the GPU in the
future... ;)

I remember seeing somethig about GPUs being used for BOINC...

A quick Google gave me a couple /. articles...
