p5b plus
g.skill ddr2 800
e6300
Im orthos stable now for 4 hours, temps are 34 idle 44 load w/ an over clock of 3046mhz fsb is set at 433, this is as far as i have tried to push this chip for now.
So no issuses here.

4-4-4-12, or at least were. I have them at 5-5-5-15 now with an o/c of 3512mhz. running stable for 8hrs, 502 fsb. Ill post some pics when i get home today.

It's a memory bandwidth thing from what I am currently reading.

It's posted over in the XS Forums. And somewhere in Ours too.

You're changing the NB chipset clock basically (Intel thing) beyond
a certain FSB that you set.

Has to do with the "straps".

As say, a 8x400 give XXX memory bandwidth and 7X400 give you actually
a better memory bandwidth.

This has something to do with the architechture of/ scaling where it actually
relaxes the memory timings.

This can bee seen in SissoftSandra memory benchies.

I know I just babbled a bunch of garbage, I am still looking into it,
and have just scratched the surface of it all.
Just spent 3 hours reading & am letting it soak in.

See if I can find that link in Intel forums for you.

EDIT:
For those interested , it's called NBCC.

Read thru them, it may help answer some questions.

You take the default multiplier, divideit by the multiplier you set.

and then, multiply it by the FSB you set,

and then, you get the Northbridge chipset clock.

So, 8/8 x 400 = 457 or 1600 mhz on the chipset clock.

but then you lower the multiplier to 7 and stability will change.
because you'll be stressing the NB chipset even more.

IE:
8/7 x 400 =457 or 1829 mhz on the chipset clock.

Even though you only changed the multiplier

Can be seen by running Sandra benchmarks.

Bottom line, the mobo/cpu (?) automatically changes to keep something
close to default speeds.
So it'll reduce memory timings for stability, killing performance?

My asumption may be incorrect and should be taken over to the mobo/cpu section
for more discussion.

but this has a lot to do with making our rigs Folding Stable.

I'm still learning a lot on this, and have my own opinions about it, but
that's another story for later.

A post from the Folding Forum, it'll get you started.

I actually spent about a week reading up on it at other web sites.
but I have an idea about it now.

Hope this helps a little more.
