WOW! Great results....how cold is "very cold" :confused:

Good one :up:

I guess my air-cooling could put any LN2-run to shame too, LOL. I just need to open the window, it's -11'C here in Oslo today, but hopefully it will get better soon. :D

Thanks guys! :cool:

I'm very proud of the stability test! 4,7 with less than 1,4V is great so far!

6°C in the Wintergarden.
Hope for wednesday...it'll be nearly -6°C outside, so -3 to -4°C inside the wintergarden.
I have enough antifreeze protection in my watercooling system! And the biggest rad ever sold on earth!
That must be possible to reach 4,9 in Vantage and 5,1 in 1m.
Hopefully I can reach 4,95 in '05!
I'll also get my 950 on wednesday, cause my board limits a bit :(

WOW! even more impressive at +6C :eek:
Incredible CPU! :D

Great bclk! You sure have a nice chip, sir! :up:

I hope so!
I think a RIIIE would be much better to reach some more points!
On wednesday it'll be the best wheather for me!

Great
Very strong BCLK Core

Jep - not bad for a Classi especially without LN2 but in fast mode!

I doubt you'll reach the same results with a 950. I've had three and they have all been worse than my 920's :(

However, I wish you the best of luck!

My maximum with the Asus P6T Deluxe V2 is 21 x 219MHz = 4.6GHz but I need higher than 2.0 CPU PLL and QPI > 1.50v to be 24/7 stable. Temp is not a problem, core 00 while using linpack gets at maximum of 53c. I will do some extreme overclocking with this chip at the end of 2011, not now, I do not want to lose it :D.

It could be, but the batch is good! 5,7 ghz was possible!
3906A350

Nice going, good luck for your next attempt! :up:

( Somehow you get better responses here than on CB... But thanks for posting it over there, I had a good laugh reading the thread! :rofl: )

Jep...that guys don't know to honor the work...clearly it's not that, what people reach under LN2 but it was hard work to get THAT under water!

heh, nice... :toast:

Great work, Em. The critical thing to remember is that clocks and other data mean nothing unless core temps are included in the screen shots.

Which one do you mean?
The temps @ Vantage hadn't reach any higher than 70°C and in 1m just 38°C!

I was using your post as an exampe of the right thing to do.
The whole idea behind OCing is to show the quality of the chip in terms of AC characteristics. The higher the temp for a given clock, the better the chip. For example, had you not shown your temps to be in the 50C range, I would have assumed your core temps were around 0C. An average chip can do 5Ghz if you get the chip down to 0C, so no big deal. To pass prime at 5 Ghz and 50C, now that's impressive indeed.

Geil!! just watch out for condensation and winter flu :D

New Results to come...

Nice mate... :up:

thanks a lot!

wwowwww!

Amazing results! Its -5ºC here in france in my location, i could try out my E8300 and E8400 again, could not pass the 4.3ghz in liquid cooling cause of the heat ( i made it when it was 35ºC outside eheheh).

But work dont give me time to spend in benching my rigs. :S

GZ again!

Em,
Core temp greatly affects AC characteristics, so screens must include core temp to be meaningful.

Here you are!

Thanks Em. Passing prime at 4818Mhz with temps in the high teens C is remarkable, maybe one chip in 1000 can do that. Could you use Eleet Util, overclocking tab, and raise the QPI value until failure? Be sure to check "enable brink OC". That will give you an official CPUZ validation automatically. Your chip could conceivably set a new WR at HWBOT. When using the QPI slider, you'll need to double click the arrow to get one QPI clock (aka Bclk) increase. What setting do you have for 'CPU impedence' and 'QPI compensation' in bios?

Auto and less...the other things, I've already done!
I don't think, that it's possible to clock it higher under water. It'll come under ln2 next week.

Wow nice run under air! What was CPU temp under load? Ambient for this run?

Privet!
Not AIR!
Watercooling! Look into the first post...ambient was 2°C :D

Привет!

Wow nice ambient here:D

The temps in Holland are below zero... Might aswell go benching soonish, maybe wait for a good -10 outside.

4.9GHz 3DMV
Very strong

Another day in paradise;)

Well done , btw nice qpi with this base clock

Nice Uncore for the Pi runs!

I wish I still had a 920... my 950 is crap :(

My 950 is also Not the best and indeed not comparable to that golden silicium.

Super result as in H2O.
When the session in the cold.

Really nice results! Good board to handle that too, never tried my chip on anything but my POS II Extreme, looks like you had fun!

Yep...it was a lot of fun, but cold!

Very impressive stability test! After seeing this my e8600 is definitely getting a thrashing tonight if it gets cold enough (it's been -3/-4c here at night recently)
Got 5.3ghz spi 1m last year on water, maybe I could get 5.5 this time around:shrug::rofl:

Shove that radiator in the snow!

Awesome results. I had a cold spell here in SoCal and managed a 4.7 3dm6 run with HT off, next time we get good cold I will try for 4.7 HT on and break my 3dm6 goal of 30k with 5850
