I have a new problem on OCing my E8600...
I can get it pass ORTHOS Small FFTs, 533x7.5 @1.248v
But I just can't pass ORTHOS, 535x8 even @1.38v...
and the time that fails is random, sometimes 30 min, sometimes 50min
it did not vary on how much juice I used on it...anyone have idea?

CPU Clock0 skew....had to set this to 100ps to get above 500fsb and 200 to go above 520.
CPU Clock1 skew....no idea how to tweak this...supposed to be northbridge related but any adjustment for me doesn't boot
CPU clock amplitude....supposed to help with really high fsb OC's but so far nothing for me.

Yeah you got that right.
Clock 0 Skew is for CPU, Clock 1 Skew is Northbridge Clock Skew.
AFAIK, As you go higher FSB, CPU clock need to set skew to a little delay with NB so that they can communicate better.
For example, with 0ps NB skew (aka Clock 1 Skew), CPU skew 200ps, the distance is 200ps. If you want NB skew to 100ps but still wanna keep the distance with CPU of 200ps, you need to set the CPU clock 0 skew to 300ps. My case is 200ps NB Skew delay, 300ps delay from CPU to NB.

So with a oc like mine would it be better to tweak them or leave on on auto.

10 x 420? Yeah leave em on auto....I only needed to adjust them above 500fsb.

I had to add 100 ps of CPU Clock0 Skew at 400 MHz FSB and 100 ps of CPU Clock1 Skew at 440 MHz. But I'm running a quad and 2x2 GB of memory. When I ran out of other options, I just tried 'em one at a time to see if they helped.

From the BIOS tuning guide:

Quote:
CPU Clock Skew0 :
The skew of clock signal for CPU; To achieve higher FSB, please add more ps for increasing CPU OC
ability. Default value is 0mV, max out put is 1500mv.
*** Recommend to add 100ps~200ps when if the FSB is higher to 500~600MHz or DRAM speed at
1800~2000MHz
CPU Clock Skew1 :
The skew of clock signal for North-Bridge; To achieve higher FSB, please add more ps for increasing
CPU OC ability. Default value is 0mV, max out put is 1500mv.
Anyone know if I should be messing with the MCH values?
I've found GTL to be a must with this quad.

Default help Im going nuts here

Ok guys could use some input here

Ok with the system in my sig here's whats going on?

I got the new video card Finley 4 days ago . Up to that point i had been using a 6800 card got the system 14 hours stable at 3700. All benches done 3dmark 01se -06 everything going grate. I get the new 4870X2 and uninstall the old video drivers and install the new card.and new drivers. everything goes to sh$$. every 3rd boot no screen. can not install or even run any of the bunch programs i mess with this for 4 days. reset bios to defaults don't help. reinstall OS don't help I start to blame stuff on my memory stick. everything i can think of. nothing helps. system boot runs occt for hours. not any 3dmark software. so tonight i got pissed went back to the old card . did a new OS install. Installed 01-06 no problems run all of them no problem. OK un-install the 6800 drivers. turn off put the 4870x2 back in turn on install the drivers and same thing every time i start a 3dmark apps its says not responding ?what the hells going on. And by the way its is still out of case
