do you mean to adjust the v-core up?
what do you have your vcore on? i'm really hesitant to go too high

also, like i mentioned before, i booted into windows correctly with my DDR2-667 OC'd to 712 in "sync mode", but i am positive it's unstable. Orthos runs fine on "stress CPU" but gives error in less than 5 seconds on "blend-stress CPU and RAM"
This is under an upped RAM voltage from 1.8v stock to 1.85v. By the way this is one of corsairs Value-select series, does anyone know how high i can up the voltage on this?

I have the ram unlinked completely. Haven't adjusted the ram or anything voltage for that matter. My v-core is at 1.41. I have run orthos for 7 hours at this setting no problem. I am on water cooling as well which is important to know.

I actually fixed the problem by switching from unlinked mode to linked - "sync mode". Does anyone know what my problem was before and how this corrected it?
Putting your ram at sync mode lowered the ram speed from 800 mhz to that of your fsb, allowing for more stability do to the lower speed.

But the speed of my RAM was 667 before, not 800mhz.

I wouldn't get his hopes up too high for 4ghz, especially not with a zalman 9500. If you could even hit it, I doubt you'd really be stable, unless your chip was an awesome one. Well, I guess it's possible don't get me wrong, if you got a sweet chip would be the only way. I'm on a lapped Big Typhoon which outdoes a 9500 already tempwise, with good temps, and my 6600 starts to max out just over 3.6ghz. I'm talking being stable here, I don't even count suicide runs where you're not really stable.

I want it stable so I don't even care what it can boot at or run a benchmark etc, above that clock. Even with just over 1.5v vcore around 3.6 stable is my max, and I'm not willing to push higher than that without better cooling. My first 6600 started to max out around 3.3ghz with all the way up to 1.5v.

Granted every chip is different, some 6600's clock better than others, but you need water cooling or better probably to hit 4ghz and be stable. Maybe with a tuniq, I've seen people get some good clocks with those on. But you'd also need a 6600 that can clock pretty good to go with it.

COOL, I found the solution!
it was to up all voltages, so now i just gotta figure out which voltage to lower to test the limit.
I'm at:
vcore: 1.45v
FSB: 1.5v
nForce SPP: 1.5v

temp at 48 with full load, which is okay i guess given that the ambient is really low.
anyone think those voltages are too high?

Oh lol you're on water. When you said you had the same setup as him, I assumed you meant you also had a zalman 9500. I was like dang, that's a freakin nice chip to hit 4ghz on a 9500!!

Darnit.
I'm at:
vcore: 1.45
FSB: 1.5
nforce spp: 1.5

and only overclocked to 3.2ghz and i'm still unstable at orthos blend.
Temp is definitely not the problem since i'm not going over mid 50s ever. Any ideas or suggestions? I don't know what I could possibly do to add stability given that this is a very low overclock.

Those voltages look alright to me. You might want to see if you can get the vcore down a bit (means lower temps). Like I said I am on 1.41 at 3.6 and very stable. You might be able to get lower vcore and remain stable.
