Well I've tried overclocking my 2.4C, and I hit 3.0 but its unstable and I tihnk my memory might holding me back. I had it at 5:4, so mem would run at 200, which it should (2x corsair pc3200 c2, BTW). I'm afraid to up the voltage, since this is my first time in overclocking business. Would it be safe to bump it to 2.8v?
YEs the modules have heatspreaders.. Anyways, I went for 3.0 again. bumped the mem vcore to 2.8v, and 5:4 ratio. Windows boots fine... I tried playing black hawk down as a light stress test, and it crashed. I know some people get more than 3.0 with stock HSF and PC3200. but I am not able to do that.
Please look at this link. You want to start at 3:2. This is a very quirky mobo. I don't like it.
You need to go into
Refresh Cycle Time = normal
Read delay adjust = disable
command per clock = disable
<Soft Menu Setup>
Dram ratio = 3:2(or 2/3 * fsb)
AGP ratio = fixed
This should allow max OC in dual channel till you get the feel for your ram settings.
If you are using winbond CH-5 then you are pissing in the wind. The IS7 hates that ram and refuses to do 5:4. I have noticed that any ram voltages above 2.65v makes my systm unstable so I keep them around 2.5~2.6v.
My GA-8IPE1000 allows 5:4 @ 267MHz fsb where as my IS7 would only around 250MHz with the same ram. My hyperX allows me to use 5:4 to around 270MHz on the IS7 but the GB mobo allows the same with cheaper ram.
One other thing, the IS7 reads temps about 10 deg. C higher than the true temp.

Memory modules have heatspreaders on them... not platinum though, as I've seen some corsair modules with platinum heatspreaders.
Platinum ... That ram would run for over $500 a stick hehe. they are only platinum color, nothing more .
