Ok I got a core 2 duo yesterday the 2.4ghz version cooled by a new Zalman 9700 and EVGA 680i, 2gb of crucial ballistix DDR2 1000, and a Single 8800GTX and I just benched this machine at stock speeds:

http://service.futuremark.com/orb/resultanalyzer.jsp?projectType=12&XLID=0&UID=7576897 Resulted in a 14,910 3dmark 05 Score

http://service.futuremark.com/orb/resultanalyzer.jsp?projectType=14&XLID=0&UID=7577122 Resulted in a 10,090 3dmark 06 Score

Overall I'm very happy with these numbers!

I also ran Quad Prime one for each core/HT, and temps at idle are 34c, max load with all 4 primes running was 55c. I felt pretty comfortable with those numbers.

Coming up, my OC attempts - I'd like to see 3.9ghz stable or higher but time will only tell, Wish me Luck!!!

Right now I'm sitting at 3.6Ghz and at Quad prime I'm 71c under load and 34c at idle.

These temps are a bit high to me, but I've read around and from what I've seen 75c is not horrible and a max of 85c is considered the limit, anyone confirm that?

I was able to get 3.535ghz completely stable at 1.35v, with max temps of 62c Here are the benches:

http://service.futuremark.com/orb/resultanalyzer.jsp?projectType=12&XLID=0&UID=7578859 Nice 4k increase with this OC!!! 18572

http://service.futuremark.com/orb/resultanalyzer.jsp?projectType=14&XLID=0&UID=7579091 solikd 1k increase with this OC!!! 11241
 
Very good start :) There is no reason to run quad prime though, that cpu is dual core and no HT, so 2 instances of prime will load both cores.

Thank you for this information. I did not know this.

OK overclocked the 8800GTX to SOC lvls which are 621/1000 and eeked out a 19408 in 05 and that run was with riva running in the back ground monitoring temps... which had hit 80c under load.

I'm going to work on tweaking my services a bit and try a run in 05 and 06 without riva running

Did you set your VGA's fan to run 100% while overclocked?

You can do this through the Nvidia driver / GPU Tweaking....

You can also try the ATI Tool which will test your card's highest overclock...

And about your CPU's overclock, very good, but stay away from 3.6ghz if you need so much more Voltage. Not worth it going from your awesome 3.5ghz with so little Vcore.
 
I set them to 100% through Riva, although I must admit either the fan is quiet or it did not spin up to 100%...

Yep I'm totally happy with a 1.36v 3.535ghz oc on the 2.4. Its damn fast and stable. I've gamed 2 days straight with the only issue being I needed to flash the bios on the 680i to counter a sata issue... Once I did that silky smooth without any issues... I'm also running the mobo at close to 400mhz using the x9 multipler, works out to 392 or 393 mhz on the mobo, I could not get it to post above 400mhz but then again that is a nearly 2x what I had on my old setup.

Final Notes, I have been able to run Extreme Mode in EQ2 with all option set to max with acceptable frame rates, I did not look at teh fps but its above 30fps I'm sure. I turned off environmental shadows and everything else is at max. The 8800GTX is a beast of a card!
 
My 2nd 8800GTX is on its way. I sprung for it to future proof my system a bit mroe than anything and with eVGA's stepup program I should be ok for a while. I will post my results this weekend when I rebench my machine... i'm wondering if I can break 20k in 06. :D This really should place the bottle neck on my cpu, and that I will look at upgrading in Q3 of 07 to a 45nm dual or quad core. I'm guesing dual core will be better for general gaming as you most likely can get 2 cores to hold a higher OC than 4 cores having to all match the overclock.

More to come shortly!

you'd probably get 15k in 3dMark 06 if your lucky anyways enjoy your system :)

Your probably right I had 12k before I'm guessing maybe 17-18k is more realistic, but i'll know sometime tomorrow...

Amazing how the 8800 series can boost the 3dmark score so much :eek:

Well it is not just the G80 that is doing it... The mobo is running at 2x teh speed, the Core Duo is about 4x as fast, the Memory is 600mhz faster, and of course the G80 is a beast!

I get my 2nd GTX today, weee

**** All i have to say to anyone upgrading their system - GET A DECENT PSU!!!! ****

Here is why: I had the antec 450w psu before and it was old and didn't have an 8 pin cpu connector and SLI connectors that actually fit... So I decided as I was going to head toward SLI that a PSU upgrade was in store. Well i installed it last night the Silverstone 1kw OP, and wow... First off with the old PSU I had ot up the voltage on the cpu to get 3.535ghz stable... I no longer had to go to 1.37 v, I can now keep it at 1.35v now that doesn't sound like a lot but it litteraly adds about 5c under full load. I gamed for the first night at the lowered voltages without a single reset. So this weekend I'm going to see what I can do with the OC now knowing i have a much cleaner / stable power!

I'm wondering if I can reach my goal of 3.9ghz on Air now... The extra 400mhz would certainly help with the bottle neck the cpu is...

aah so that's the reason why I lack the ability to get a stable 3.2ghz overclock
