So, yesterday I did an upgrade-on-the-cheap:
M0 E2160 + GB 945GCMX-S2 + 2×1GB/800 + Samsung T166.
As Im waiting for 8800GT or HD3800 to be available, I'm using the IGP now.

The 945GC chip is supposed to support 333FSB... supposed...
the factory bios didn't even let me oc, it reset the freqs to default upon
restarting from bios. With the updated bios, it's stable at 9×266=2400.
However, raising the fsb to 300 and vcore to 1.375 resulted in freqs reset
to default at the reboot. Setting even 275 in windows with the GB ntune
utility resulted in colorful lines all over the screen... the type when video
card's vram die, except the igp doesn't have ram.
Also, setting the "OC to 1333FSB" in bios to enabled resulted in a boot screen
with colorful lines...
I have a lot to experiment with it, I didn't have much time to so far, but this
is a bit confusing. The 333FSB may have been because of low vcore, but the
rest, especially the lines? Low vfsb? PCIe unlocked? Dud board? IGP doesn't
like oc?


Oh and Orthos made my cpu block obsolote even with 2.4G
Maybe the board's bios is measuring it wrongly, but because I set it to alarm
at 80C, it went buzzing after a few minutes of Orthos, with RMClock showing
50-53C. Funny that my old A XP2400+ 2@2.33 stayed around 39-40C even
under full load... low surface area of the block and cap vs no-cap, but this is
still a drastic difference.
