I'm pretty sure it's B. You should be ok up to a good speed with 1.35V, and that's a relatively safe voltage.

Ok. My goal is 3.80ghz, hopefully I can get that with 1.35v cause 1.4v is always risky

Yep.... 3.8ghz just restarted itself after about an hour of prime95 but passed intel burn test. Are there any more settings I could mess around with like ram voltage or something, cause if 1.35v dosent do it then theres gotta be another reason for this
The good news is 2 intel burn tests and the hour or so of prime95 only maxed a 50c so maybe 1.37-1.4v wont be a problem. The noctua fan I got plus the thermal paste and extra scythe fan keep it extra cool.

3.8Ghz is too high for 1.35V, I had to use 1.4V for 3.8Ghz. To be more precise I used 1.43V, but without LLC, so under load it came up as 1.36V.
I haven't got 3.87Ghz (455) stable yet, as I haven't really got beefy enough side fans to cool the northbridge, as that needs lots of extra voltage to make 3.87Ghz, and thus, runs at about 70ºC in games, and crashes when it reaches that temperature.

Remember, I'm also using a HAF, and a Thermalright Ultra-120.
I was using +0.30V MCH, +0.25V FSB, +0.30V RAM and 1.4375Vcore.

I cant seem to get 3.8 stable AT ALL.... Im at 3.5ghz super stable and I think ill just stay there as its still a great overclock (especially since im coming from a 3.00ghz amd dual core) Thanks for all your help. I might try and see if 3.6 is stable in the future but anything higher requires some knowledge I dont yet have.

Well, how hard are you trying? Beyond 3.4Ghz requires an FSB beyond what the motherboard is designed to run, so the Northbridge and Front side bus will need overvolting as well, not just the CPU and RAM.

I never even changed the ram voltage and I dont know what settings to change besides vcore and FSB

Up the G(MCH) voltage to get higher FSBs.

For some reason my computer wont even boot into windows now. Once the black windows logo finishes loading it restarts. I loaded the optimized BIOS settings and then the Fail safe, both giving the same results. Did my overclock damage the system??? this is what I had FSB at 412, vcore at 1.35v and ram at 2.00D... what could the problem be or does 3.5ghz need something more. also take note that one stick of RAM was DOA so it might be the second RAM stick.

Just installed xp on the second HDD and works fine at factory settings. I see some wierd files in the c drive that wouldnt boot, could be just a bad virus. Ill try the overclock tommarow

well I would NEVER try to overclock on a single stick of RAM, let alone a single stick I suspected was faulty - so get that changed as a priority before you push high speeds. 1.35Vcore is ample for a Q9550, right the way up to 3.7-3.8 on most chips. With 2.00D RAM (I assume it's PC8500? PC6400 will struggle from this point on) you're ok at this point, but the MCH will probably need an extra +0.1V, depending on how good your board is it might also need +0.1V on the FSB. For my 3.65Ghz overclock I use +0.20V MCH (+0.20 is the same as 'Auto' on Gigabyte boards) and +0.15V FSB - which is the 'safety limit' for the latter.

CPU Termination is the voltage you're looking for.

Ok Ill give it a try. Is Prime95 the best for stability or should I just use Intel burn test? I usually pass the burn but fail the prime a 3.8ghz

IBT is a short-term stability test (don't run it for hours, it's just needless trashing of your cooling system), the best long-term stability test I'm afraid is simply to use the PC as you do - the only way you can find out if it's stable with the programs you use is by using those programs.

That was actually what I was thinking.... but I know you still need atleast need a program to let you know if your stable on an average level.

Seriously? I've never found an accurate program. I can be stable for hours in a program and get a crash within 30 minutes playing a game, or I can have a BSOD within minutes in a stress test on a system that's been stable for weeks.

Just realized why I?m having so much trouble overclocking.

And

These are all forums with the same ram and motherboard showing some of the same problems I had. Those bad sticks of ram I had was actually the compatibility issue with the ram/mobo. It won?t post in dual channel in slots 1 and 3. I reseated to 2 and 4 and it works. It still resets bios randomly during post saying I have a bad overclock but this is from like 3.4 GHz with 1.3vcore and ram at 400mhz. that?s about the safest overclock you can do. It?ll just restart during post and I?m back to 2.83. The ram works in my foxconn motherboard with no problems.
I?ll just look for some good 1066 ram

Never heard of any issues using Corsair RAM with them.

yeah I know. Thats gonna be my first choice from now on. just to be sure, do you think all of these weird problems ive been having is due to the RAM?
And could you recommend some good 1066 RAM thats 60$ at the most? It dosent have to be corsair but good quality.
Thanks again

Forgive me for not remembering exactly what problems you have, but if you suspect memory incompatibility, I'd say you may well be right. Ftr, I have never had a compatibility issue with corsair RAM except for in one of the worst motherboards ever made, a P5N-E SLI.
