e4400 vs e6300

[Mark620]

my e4400 is spanking my e6300 :shrug:
same OS and the e6300 has a higher OC :confused:

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.

linky no workey for me...

Yep, linky no workey for me either, WII.

Sorry about the linky, I have no idea why it doesn't work especially being one of ours.

Do a General search for NBCC in our (ocf) Forums.

It'll return like 6 posts to view.

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 :eek: 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. :p
