3930K running at 4.6 GHz. Can do 4.8 24/7, but its far more power inefficient this way. Water cooled with 3x140 radiator + 2x120 radiator. Temperature is in low sixties(Celsius).
Fastest one I had was 2500K, able to run SETI at 5 GHz on air, but again, very power inefficient, so I ran it at 4.6 GHz, where it used least power per WU.

...cooled to -27.5 centigrade.


None of my CPUs are overclocked and dont even come close to your values, however, I have always wondered, do overclocked CPUs need to be cooled to subzero temperatures to work properly? Wont a decent room temperature or even something like 10 degrees C be sufficient?

My FX 8150 is overclocked to 4.4 GHZ with aircooling.
Its running stable at 56°C for over 2 years now.

To underline Mark's comment, new new cruncher is based on an AMD FX8350, running stock at 4GHz, until a few minutes ago it was running a stock cooler, which I have changed for water cooling due to the ridiculous noise levels.
Such is progress, we forget that Mark's rig was at the bleeding edge when he built it, but now it is "middle of the road", if he will excuse me for swearing in his presence...

I just wander what he would build today given the time and money that he spent those years ago.

Mine is the 'Frozen One'....
An i7 920 rated at 2.67Ghz, running at 4.25Ghz compressor cooled to -27.5 centigrade.

What are you folks running up in that range?

Over 4Ghz.

Meow?

Now, that's what I call overclocking!



Myself I don't OC, I build long life stable systems that run stock and do it well, most systems I've built are either still running for their owners or have gotten so old they've been de-commissioned . I use proven hardware and always pick a proper chipset for the design at hand, and I pair RAM specifically to the CPU in any given build. I like decent but not high-end as the price-performance value is best found in the 18mo old hardware range. That's the philosophy I use.

Anyways I haven't built a *new* system in over a year, but my fastest CPU is a Xeon E3-1230, running stock with 16G RAM in a small quiet server (goal was energy efficiency not crunching :-)) that is more than adequate for my purposes. Six HDDs on the serverboard, all in a micro-ATX package. :-)

My fastest rig is my I7 3770 at 3.40 GHz. Im running stock apps on both CPU and GPU. And it is slowly cacthing up to my I7 920 2.67 GHz. running lunatics op apps.

Mark you could probally overclock an I7 3770 to 6.GHz plus using your compressor.

Id like to build another I7 But finances have ruled that out.

Of course its much easier to overclock a CPU with liquid cooling.
I`ve sold a FX 8150 @5.6 GHZ with liquid cooling.
Myself i prefer a good aircooling.
Maybe i`m old fashioned.

My system looks like this below Win8 only see 16gb ram in dual channel because the asus p6t does not have win8 drivers so I need to upgrade the cpu and mb to get full use of my memory sticks. I had a Thermaltake V1 Max-Performance CPU Cooler with Massive 110mm Blue LED Full-Range Variable Speed Fan CL-P0401 but the pins went bad and the air temps were in the 60's and then I had to use the stock intel cooler and the temps were in the mid 90's. With the Antec Kuhler H2O 620 Liquid CPU Cooler System the temps are in the mid 50's. I run Jason's Lunatics_x41zc_win32_cuda50.exe and AK_v8b2_win_x64_SSE3.exe with a rac of over 38,000 and climbing. The AZZA Solano 1000 CSAZ-1000 Full Tower Case (Black) runs real quite and cool compared to my old case which was noisy and I had to leave the panels off and had a fan blowing on the video cards. In the old case the cards ran real hot in the 80-90's. I moved the 2nd card to the 3rd slot and it cooled down. Now they run in the 60's with the fans at about 50%.

Operating System
MS Windows 8 64-bit
CPU
Intel Core i7 920 @ 2.67GHz 57 °C
Bloomfield 45nm Technology
RAM
24.0 GB Dual-Channel DDR3 @ 534MHz (8-8-8-20)
Motherboard
ASUSTeK Computer INC. P6T (LGA1366) 52 °C
Graphics
G276HL (1920x1080@60Hz)
767MB GeForce GTX 460 (nVidia) 66 °C
767MB GeForce GTX 460 (nVidia) 67 °C
ForceWare version 307.74
SLI Disabled
Hard Drives
125GB OCZ OCZ-AGILITY4 ATA Device (SATA)
Optical Drives
HL-DT-ST DVDRAM GSA-H10L ATA Device
Audio
Realtek High Definition Audio



I just upgraded since September.

Coolmax ZU Series ZU-1000B 1000W ATX12V v2.31 & EPS12V v2.91 SLI Ready CrossFire Ready 80 PLUS Bronze Certified Modular Power Supply = $87.74

win 8 pro upgrade = $39.99

Acer G276HL Dbd 27-Inch Screen LED-Lit Monitor = $244.76

AZZA Solano 1000 CSAZ-1000 Full Tower Case (Black) = $114.99

Antec Kuhler H2O 620 Liquid CPU Cooler System = $59.99

OCZ Technology 128GB Agility 4 Series SATA 6Gb/s 2.5-Inch Solid State Drive( SSD) With Up to 420 MB/s Read And 72K Max.IOPS- AGT4-25SAT3-128G = $99.99

So these upgrades cost a little over $700 including S&H so Iguess I will get the new I7 3820 and ASUS P9X79 which will replace the i7 920 and the ASUS P6T board and get 2 more sticks of corsair vengeance memory and keep my 2 460 cards

Thanks for the information and those wonderful photographs Mark. Like others have pointed out, I too am curious to see what kind of monster you would build with the present day hardware. And I do remember reading that you may add a 9th rig to your farm. So go for it if time and resources permit.

I too, like Ex, build stable systems that are never overclocked. And my hobby is to give second life to old computer components that others may discard as junk. Built and sold many such systems which are still running cheerfully. Due to the fact that the outside temperatures regularly cross 50 degrees C here during summer, I cannot overclock any aircooled rigs and do not want to chance it. And, I had to put all my rigs on high shelves to protect it from an over curious baby who is just starting to walk.

I am supposed to know which Intel processor is the best one.

But how many are there which currently which beat my Core i7 960?

Core 2 Duo? Core 2 Quad? Apparently no. Core Extreme? Apparently yes.

Google it and you get several suggestions back in return.

But there are so many new ones out now which are having different names and designations. You may be able to find several of these processors being used here.

So how well are these processors doing? Is a comparison list available?

Please let me know. Thanks!
