;) I Can't wait to share my happiest moment in life so I'm not going to be wordy this time. Pictures speak a thousand words.

Finally lapped my Thermalright Ultra120 Extreme. The heatsink base was extremely CONVEX!
The lapping work took me more than 6 hours. Used 320x2, 400x2, 600x2, 1000, 1500 and 2000grid wet/dry 3M sandpapers. (more details and pics on this in the air cooled forum ;) )

NOTICE: I'm using Vista 64bit OS. So I can only open Speedfan 4.32 to get the core temp.
Coretemp 0.94/95 and Intel TAT aren't supported in Vista x64.
Before you start flaming about Speedfan's core temp inaccuracy, know that Speefan 4.32 assumes the max Tjunction is 85c instead of the actual 100c from the Quad.
You've to ADD +15c on top of Idle/Load temps to get the actual core temps. And it's still an incredibly low temps for a high-end air cooled quad at stock settings.
*Maybe my lapped job did the trick;)
I've also posted the temp readings from BIOS and Asus AI suite as a reference. Those temp are always lower than the actual core temp.
So after you've added +15c on top of the core temp reported from Speedfan 4.32, the core temp is accurate and does get higher than the temp reported from Asus AI Suite and BIOS.:)

Here's is another reference temp reading/OC from my previous setup before I just swapped to the G0 Q6600 last night.
This is just to show you that Speedfan 4.32 is actually picking up the core temp accurately given that C2D has Tjunction of 85c instead of 100c from the quad.

Talk about cheap Quad Core thrills! Preliminary OC @ 3Ghz and temps are still amazing on AIR!!
I think I may have a good chance beating some watercooled Q6600 rigs :cool:
Gotta give myself props on my lapping job again :D

Wow dude that's some pretty good results. Guess the G0 stepping and the Ultra-120 Extreme make a beautiful combo.

I had a question though. How do you tell if you have a G0 stepping without CPU-Z? Isn't there a number you can read on the box to find out? I ask cause I just got my quad core today but I'm still waiting on my mobo so I can't verify what stepping I have yet.
 
I find that so hard to believe. What's your room temperature?

Quad load @ 30c... There's got to be a bug (no offence OP) in speedfan... Since the thermal TDP of the new stepping is 20w less than the old B3 chips... I bet it's calculating the Tcase wrong!

The Ultra120 is dumping the 110w of heat that chip is outputting... With about a 10c delta to air. That's crazy in it's self.
 
well if this is all legit then it seems that the q6600 g0 stepping is strictly better than our old e6600s

er, and I am confused: why does orthos report "4660mhz" when you have it clocked to 3.73ghz? Does it assume you have 1:1 ram for some reason lol?
 
Speedfan reports 15 degrees too low. So he's getting 45 degrees under load. Still REALLY good, but not impossibly so.

This is legit, I got the same batch as him and I can get this as cool. I will bring some proof tonight by running at the same settings as him. Hwoever, his Ultra-120 Extreme is lapped and mine isn't and seeing 52C (speedfan temp, add 15C for more realistic temps) on the hottest core at 1.375v is not bad. I didn't try 1.300v for 3.4 yet.

Yep, Xilikon, Dazog and I all got the same batch Q6600 G0.
However, mine has the lowest temp and follow up Xilikon.



INCREDIBLE !! I can't believe I'm on air and still having this unreal quad core thrill....am I dreaming?! :D

17c at idle. the absolute best an ultra 120 extreme will do is around 9 or 10 degress over ambient. this would mean your room temperature is a little less than 10c. sorry, but i dont think the room your pc is in is quite this cold. this is the temperature inside my refrigerator, also the recommended temperature for serving heinekin.
 
wow nice temps, but the problem i see is i have the same setup with an older q6600 and my temps are like on average 15c higher then yours.
 
read the thread, he said, they're 15 degrees lower than actual temps.
the g0 looks mega though, hope i can get one in november, whats overclocking like?
 
You guys have me convinced. Placed on order from NCIXUS.com, crossing my fingers it's a G0.
 
I believe that SpeedFan 4.32 assumes a maximum junction temperature of 85C for the Quads when it should be using 100C. You need to add 15C to the SpeedFan reported temperatures.

Reported Temps = TjMax - DTS ( DTS is the on chip digital thermal sensor reading )

The next problem is that at idle I don't believe the Core processors report the core temperature 100% accurately. With my B2 processor and a Tuniq I can go a few degrees below ambient at idle but it is very accurate from 45C to 85C. The on chip sensors were designed and calibrated to control the thermal throttling and shut down of the processor. They were not designed with reporting idle temperatures in mind and nowhere does Intel document that they should be used for this purpose.

Your SpeedFan 4.32 load temps +15C look very accurate and very nice. Keeping the volts down makes a huge difference in keeping the temps down. NCIX is going to sell out quickly with posts like these. :D

Edit: Some guy in southern Texas had his NCIX Q6600 delivered in 18 hours via FedEx. Woo Hoo!!!!

Indeed. I just placed my order, switched from an E6750 to the Q6600 at the last second thanks to this post. I was just sick of agonizing over whether dual or quad was the way to go right now.
 
There was a guy here hitting 3600 MHz last week with a revision G0 E6550 at 1.35 volts or a little less. The only difference is now you've got 4 cores smoking instead of 2. I knew these G0 Quads were going to become the future kings of bang for the buck.
 
You can use core temp. Run the command to disable driver signing in Vista 64 and voila :)
 
i just realized your name is an Italian desert that i really like! lol :D
 
yea lets see some coretemp readings or TAT readings! either way, it seems your new proc is pretty amazing. gratz to you mang!
 
Coretemp 0.95 works fine for me in Vista 64as long as you run it as admin.

At 3.33Ghz I am topping out at 57c but need near 1.425v to get it.I dont like the noise my new VI makes at that speed (2000rpm) its putting out 86+ CFM :eek: powerful yes,but too noisy.I have decided to compromise at 3.03Ghz at low volts and very low noise.I'm just happy that my 4 gigs of ram runs at this speed without throwing a shit fit. :D I know in my bones that my ram is holding me back.I am going to try my Ballstix PC8000 on the weekend,and see what that gives me.But let me tell ya @ 3Ghz (9x334) This thing is just crazy fast. :eek: I encoded a movie early this morning (Millenium Actress) just to test it out,and @ 3.33 it ate my wife's X2 3800 @ 2.33Ghz and spit it out,and ran cooler,with less volts !

With the V1 on high,and 2 120mm case fans on push pull in the case @ 1400rpm,plus the side 92mm in my Thermaltake Soprano @ 1800rpm it was peaking at 55 to 59c per core.Orthos'ing four cores gets me the same or 1c higher temps.I ran Orthos for near 2.5 hours early this morn just to test its stability,and got no errors at all.At one point core 3 hit 61c,but thats as high as it got,and it was only for a few minutes.These temps are with ambient around 24c to 26c.The new VI is IMHO as good as anything out on the market currently spare the 120 U E.But I am getting temps within 99% of a regular 120 with high CFM fan.It matches the Tuniq in my testing when on high only.What I like is the low low wieght,and incredible ease of installation with the V1.That and the low 43.99 price I got it for @ NCIX.I had to take my mobo in to work to get it flashed,as my E6420 died early this month.Oh,the mobo,It arrived with bios 302 :(

My 6420 would not go over 3.2Ghz no matter the ram,or board,so I am a VERY happy camper right now. :D

Between this little gem and the 170 shares my wife and I own of INTC,I am not complaining.Its been a good month :) :eek:
 
The moment you all have being waiting for: 3.6ghz Prime stable on air!

1.38v loaded and *62c = 47c + 15c (Actual max Tjunction is 100c)
Ambient temp = 29c right now in the summer afternoon!
Overall it's one helluv killer chip! :D

^ Thanks for the better explanation.

outstanding good news, well done guys. Cant wait to receive shipment from TankGuys
 
Im glad to see you happy.

I was very pleased with my q6600 b3. It can OC 3.7 and more. But for piece of mind, I run at 3.2 to 3.4. I doubt anyone wont hit 3g's on these chips. For most, that damn good for what you're getting.
 
Nice... I may have to venture into the world of OCing with this chip... :cool: I already lapped my heatsink :D
 
Great!
I'd love to see many more retail G0 Q6600 OC results.
retail G0 Q6600 looks very promising, at least better than retail G0 E6x50s in general - High clock yes but also high volts..but low temp as always for G0s.

Please keep this in mind though, don't expect your G0 Q6600 to have an identical overclock-ability. It's still a luck of draw. I wasn't having high hopes for running Q6600 G0 + air cooling so I worked my ass off lapping the TR Ultra120 X and hoping that I would at least hit 3.2ghz during hot summer days. And the result was overwhelming.

So start with little expectation and you may find yourself gain much higher reward at the end;)


As for lapping, I think lapping G0 IHS isn't really necessary as they're running very cool already and my G0 IHS in particular is very flat and it doesn't look like those convex/concave IHS I used to have with C2D which I had to lap them and void the 3yrs warranty.

However, get the best air cooled heatsink - TR U120 X and lap it is crucial for max OC success on air :)

Was it a later packaged B3? Like June-July?
