I will try my luck with this PC2-8800 kit as I need to order a new kit ASAP and can't wait for PC2-9600 kit to become available. If I've got bad luck with it I might swap to the other kit in future.
EDIT: WTF, the ram stick I thought was dead is alive and kickin again, zombie Team Xtreem RAM stick ftw!
I can assure you I tried at least 6+ times unplugging and plugin in it again and tried different slots and it always never started but it always started on the first time I tried with the other stick. Then this last time I tried to start it up, I pressed the power button almost immediatly after flipping on the PSU power switch and somehow comp booted. TBH though, it's probably a sign that it will die sooner or later as I've already got some random crashed in UT3 which I've thought been CPU or mobo instability but perhaps it's this RAM stick that is the cause.
As for the G.Skill set I think I'll still decide to at least give it a try and of course provide you with results in that case as many haven't tried this set out yet and if it doesn't reach the desired DDR2-1200 mark (or DDR2-1000 4-4-4-x) I might keep this old micron D9GMH set a bit longer unless huge problems with instability arise.
Oh and here's the zombie ram in action again at dual channel in the 24/7 config:
Not bad for these clocks, one of the reasons I haven't considered upgrading to 4GB earlier as this is a quite fine 2x1GB DDR2-667 3-4-4-8 specced D9GMH ram that only require 2.2v to reach 4-4-4-x @ DDR2-1000+ or 5-5-5-x close to DDR2-1200.
