Hey guys,

I just upgraded my computer and thought I would post my results with my new gear. I'm currently running the following:

Intel C2D E6600 L640A773 - 80557E6600SL9S8
eVGA 680i P25 Bios
G.Skill 6400PHU2-2GBHZ
Zalman 9500 (No Led)
Cooler Master Wave Master
Enermax Liberty 620W
vNvidia 8800GTX
Creative Audigy 4 Pro

Ok, eveything runs great at stock speed and I score 9,998 in 3Dmark06, yay. I think multitasking is a tad more responsive when I get a lot of tasks going than my old 4400+ X2. After about an hour of "wow, this is great" I start my journey down OC lane. It's been rough. I was able to get the computer to post at 3.9GHZ and if I se the vCore to 1.55 I could almost get into windows but it would blue screen everytime. So I started backing it down and found that I could get into windows and do regular tasks at 3.6 1.45v. The problem is it's only stable in Orthos for about a half an hour. For those of you that are wondering, my temps are 43c idle and 64-67 load for the CPU and 33c for the system (according to nVidia Montitoring utility). My case is running 2 Thermaltake 80mm Tornados (those orange screamers @73CFM) for the rear exhaust and top intake. A 92mm panaflow side intake at about 54cfm and two 80mm front intake fans from coolermaster that came with the case.

I have a lot of work ahead of me when I get home tonight and I think I may have to play with ram, SPP, MCP and HT voltages. Currently SPP is at the max, MCP is by default running at 1.5, and HT is at 1.25 and there is room to go a little higher on that setting but I don't know how much of an impact that will have and what is the safe max voltage for it. I remember my old rig would crash like crazy before I upped the ram voltage a tad from 2.2v to 2.3v and then it was stable and that was at stock speeds so maybe it's as simple as upping the voltage on the ram. It's rated for 2.0 to 2.1v operation. I have it running at 2.0v currently. The timings are 5-5-5-15. I haven't tried tweaking the ram yet. I want to get a stable CPU OC first.

Anyways, I was curious as to what voltages some of you are using when OC'ing your E6600 with an eVGA 680i mobo. Also what kind of temperatures are you getting using Air cooling. I plan on using OCCT when I get home tonight to try and isolate what my problem areas are so I don't spend a week with these long test runs trying to figure it all out.

Your thoughts and or suggestions are greatly appreciated.
 
I am watercooled so I can't really compare temps, but I am having all kinds of problems getting past 350-375 (1400-1500qdr) On my e6600/evga 680i. I have tried everything to get my machine to post on anything past 1500qdr. If I put even 1510 with voltage really jacked up 1.55-1.65 it will not post. Same goes for 1600, 1800 etc. Right now I'm @ 1500qdr @ 1.5625 vcore which I think is a little high for my speed (3.375ghz) and I'm not even orthos stable @ 375fsb, it crashes my machine after about 20 minutes.

Only thing I've found to be 100% stable for me is 1400 fsb @ 1.45vcore running my ram @ 5-5-5-15 (it's rated speed) vmem @ 1.9v.

I run SPP & FSB @ 1.5v and running out of combinations to try. I've also tried dropping the mult and going 400-500 fsb and it would not post.

This probably doesn't help you at all so I apologize, I just consider myself to be in almost the same boat wondering what other setup I could possibly try
 
I'm was able to run Orthos at 435mhz x 6multi for about an hour while surfing and listening to music before rebooting to try OC'ing with a 9x multi. I could not post any higher than 435Mhz, so that's my ceiling.
 
Well then I'll just keep myself up to date. :p

I upped the SPP voltage to 1.55v and the ram to 2.125v and left everything else as is. I did two runs of OCCT and passed both times, once at 3.6 and a second at 3.64. I used the Auto setting which is CPU and RAM. 3DMark 06 completed this time around and I scored 11193. This is with stock ram at 5-5-5-15 2T and stock 8800GTX speeds.

I was able to get to the desktop and browse the web at 3.9 1.58v, but I failed OCCT in about 2 1/2 minutes. I guess I need much better cooling and more juice but that is out of the question. If I had access to a nice water cooling rig I would hook it up just to see how far this chip would go just for the hell of it but I think the difference between 3.64 and 3.9 isn't too big of a deal since the jump from 2.4Ghz to 3.64Ghz gained 1195 points in 3DMark06. If my math is correct it's .96 points gained per Mhz increase (1240Mhz difference) so another 260 points gained by going from 3.64 to 3.9 isn't noticeable and not worth the extra heat and stress from the high voltage needed to attain that clock. Me thinks I'm happy with 3.64Ghz.

Now that I have found my sweet spot for the CPU 3654Mhz (1624Mhz QDR * 9X multi) I can start on the ram. I hear the sticks that I am using should be able to do 1000-1100 at 4-4-4-12 and even tighter with some tweaking. Anyone here using these G.Skill chips have some advice for me?

You know, I thought the ram wouldn't affect my CPU overclock but it did. Once I raised the voltage on the RAM I was able to complete 3DMark06 runs where it failed consistently with lower settings. I think you can try upping the SPP to 1.55 as well. That might help. That's where I have mine. Are you using the P25 bios? That's the latest one.
