I had finished speed binning one tray of 3770 CPU and decided to start on 3930K for my systems. For the previous graphics test I used the Corsair integrated H100 water cooler on the X79 rig but when binning CPU's for 100% stability I wanted to see how much better I could do in terms of temps and clocking when using a custom solution. My systems will contain the best cooling available water and up so it makes sense to bin CPU's on such a water loop.

Its the V8 kit I am looking at here which has a dual rad like the Corsair so it will be interesting to see how much better a kit of similar dimensions in the case dissipates the heat of X79.

I mounted each cooler using arctic silver paste and left the loops running at stock with 100% load using Prime blend for one hour before I started taking actual values. At each level I then ran the system with prime for a further 20 mins plus.

On each test RAM is in quad channel 16gb at 1866mhz.

Here is how the Corsair solution performed:

Stock:



Top temperature was 51C on any core after 20mins Prime.

Overclocked to 4.6ghz which on this cooler needed 1.41v



Top temperature was 72C on any core after Prime 95. This was realistic the limit in terms of 24/7 overclock on this cooler as 1.41, 24/7 is really pushing it.

Overclocked to 4.7 which on this cooler needed 1.47v



Top temperature was 78C on any core after 20 mins Prime 95. I could not get any further clock stable with this cooler as heat was becoming a massive problem along with volts required.

Heres how the OCUK V8 Kit Performed:

Stock:



Top temperature was 49 which was 2C better than the Corsair.

Overclocked to 4.6 which on this cooler required 1.395V:



Top temps on this overclock was 65 which was 7C better than the H100.

Overclocked to 4.7 at 1.47



Top temps on this overclock was 71 again 7C better than the H100.

The top overclock I got out this CPU with the Custom loop was 4.8ghz with 1.455 volts.



The maximum 24/7 clock on the Custom kit was 4.7 compared to 4.6 on H100.



With voltage around 1.4 and temps under 70C your good to go.

This clearly shows that temps where the limiting factor for overclock on the H100 which did perform admirably in its price bracket and surprised me abit.

Furthermore with two 1850 Sythe GT fans the Custom V8 Kit was much quieter than the H100. On both coolers I ran the fans on maximum speed to get best cooling possible.

To sum up

The Corsair does very well at taming the heat of X79 to a 4.6ghz CPU clock 24/7 and a max of 4.7ghz. The V8 Kit did 100mhz better and 7C better on heavily overclocked CPU. Attaining 4.7ghz 24/7 and 4.8ghz max safe. The V8 was considerably quieter then the Corsair in operation.

Any questions or comments please fire back!!!
 
HI there

The coolers 8 Pack used were these:-

Extreme Performance CPU Cooling
Have a PC case that supports a top-mounted 240mm radiator? Take your CPU cooling to a new level. H100i starts with the advanced design of the Hydro Series H80i, and adds a double-wide radiator for even better performance.

Corsair Link Monitoring and Control
Monitor temperature and control lighting and fan speed on your screen. No additional hardware is necessary.



Self-contained Cooling System
Hydro Series H100i comes pre-filled, and never needs refilling or priming.

Dual Radiator with Custom Fan Design
The 240mm top-mounted radiator provides maximum surface area for maximum cooling power. The 120mm fans use wide, low-pitch blades for better static pressure to noise ratio, offering improved efficiency at lower noise levels.

Built-In Corsair Link
No additional hardware is necessary – just connect the included Corsair Link cable to a USB header on your motherboard and download the free Corsair Link Dashboard software. You can monitor coolant temperature and adjust cooling performance directly from your desktop.


Tool-free multiplatform magnetic mounting bracket kit
The modular design makes installation simpler, and it’s compatible with Intel and AMD processors.

Large-diameter, low permeability tubing
Minimal coolant evaporation helps ensure long life, and the resilient material offers both high flexibility and excellent leak protection.

Good comparison :)

But yep, Gibbo appears to have listed pricing for the V6 kit (single 120mm rad)?

Still well worth the near twice the price over the H100i @ £180, the OcUK kits have great performance:value since the refresh and are a great introduction into watercooling.
 
The kit was very easy to put together I must say and looks great too. It also has the flexibility of mounting the rad where you want as the tube lengths are not fixed. The other plus for me with the kit is you can add to it with another rad and fans for graphics. With the Corsair there is no upgrade path.

The H100 did do a good job in its price bracket though.

CPU's speed binning means we see how fast they can do. It makes things much easier when building a system to a certain spec.
 
There may be a (small) additional market available then. Currently you sell a mb/cpu/ram bundle with the bios set for a given (high) frequency, and provided the end user keeps it reasonably cool and uses a decent power supply all is well. This is probably done using a bios template that usually works followed by testing / minor tweaking - i.e. a labour cost.

Would you consider selling the speed binned cpu's by themselves? Include in the sale something like "frequency achieved using #motherboard, #ram and #cooling" but sell the chip individually. It de-risks overclocking for the end user.

I expect the frequencies reached follow a normal distribution. So some speed binned chips are really only good for stock speeds, but these are few. Most can be run at a significant increase in speed (4ghz for a i7 920 - I'm a bit out of date!) and these are the ones that I think would sell in volume. You'll also find a small number that work especially well - these few would sell at significantly over retail.

An idea anyway. Cheers
 
Thats only an hours worth of testing so temps should improve when the as5 has time to settle.

Saying that I'd love to see temps whilst running ibt maximum lol

I can see people getting upset if this was done

If an i7 3930k is binned @4.7ghz in an Asus RIVE that does not mean it will run at that speed in a different mobo.
 
Of course. Similarly changing RAM can change the clock, or even using a different, nominally identical RIVE. Or a different guy choosing the settings. For better or for worse. Writing a caution to that effect should suffice though - the novice friendly option is clearly the bundle.
 
I don't want people jacking all the good chips! At least now it's up to chance, I don't want to pay a premium to get a decent chip when I might get one for the same price. Ivy is pretty much guaranteed a 4.5GHz OC, so maybe some really exceptional chips would sell, but why bother otherwise.

The really exceptional chips I find out of the system OEM stock will be kept for 8 Pack system builds. The next best will be put in the high end overclocked builds and so on. Retail chips will not be binned at all so thats a silicon lottery. I dont want average chips in my systems, hence the binning process.

Bundles will be available yes later but I doubt just chips will be for some time as there is too much room for end user error.

Are you saying here that the chips supplied in OCUK stock speed 3770K systems have been tested and found inferior to the ones supplied in the 4GHz systems which in turn were found inferior to the ones in the 4.5GHz systems? (Asking for clarification as it certainly sounds like that).
