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.

So what kind of clocks are we to expect in 8pack builds? When you say the best chips, what criteria are you talking? Lowest volts/temps at 4.4GHz? Or highest stable overclock?

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).

I think he just means the overclocked ones are binned, and the stock ones aren't tested asides from usual function. I don't think they keep the rejects for stock builds, but I could be wrong. I doubt anyone running stock cares about what volts/temps they can run at overclocked speeds. Presumably they use the OEM chips in their builds so it's possible they'd be tested as not ideal for 4.4GHz

No chip is inferior to any other!!! where do people get this from.

So long as it runs to Intel spec in a stock build, 4.0 in 4.0 build and so on and so on there is no issue at all of inferiority. They are just CPU.

Here at OCUk we have hundreds of CPU I can only test a fraction of them. In the real world its pot luck what a cpu will clock to. I am helping the tech dept as they now know what a specific CPU can be expected to reach.

8 Pack systems will be highest safe overclock for 24/7 on all components. So an 8 Pack build will have Overclocked CPU, Overclocked RAM which will be highly tuned and Overclocked single and multi GPU.

Exact specs are yet to be determined as we need to know what silicon we have in hand before finalizing this. Hence the binning procedure.

It was implied by what you said hence why I asked for clarification. Thanks for clearing it up

Intel engineers cringe at how users on such forums as this use that silicon destroyer. I would never subject my chips to this.

Some of us use processors to solve simultaneous equations. Intel burn test, as far as I can tell, solves simultaneous equations in a loop. This seems to be pretty close to "real life" use.

Sad face

Manufacturing variability?

8 Pack · 15 Jan 2013 at 14:32

Use your PC then not IBT!!!! If your applications are so intensive use them!!

Yeah manufacturing variability is the key difference but as long as they run to spec the CPU manufacturer is not so bothered about this. Overclocking is not there priority.

I never use Prime95 or IBT when I build a system, I just use the PC for benching/gaming and adjust the settings. All 4 of my PCs are rock solid stable.

I have an old copy of Prime95 but the only time I will run it is when someone has done a review of a bit of kit and I want to compare results like for example a CPU cooler.

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.

You serious? £180 to gain 100mhz over something half the price. Crazy.

A decent air cooler will get you 4.5ghz.

Interesting to see what can be done though with the right kit and everything setup correctly.

Some impressive results from the h100.

pgi947 · 15 Jan 2013 at 21:12

Totally worth £180, better performance, noise not to mention the potential expansion into GPU's. Custom water isn't cheap though so I can see how the initial cost can be off putting to many.

IMO 8 Pack probably had room on the custom water to push the max OC past 4.8ghz too.

ZardoZ · 15 Jan 2013 at 22:11

if you use the same fans which is the most silent?

+1

I use a H100 on one PC and a Custom water setup on another. The H100 runs 8c or 9c hotter with 4 fans on it running flat out making quite a bit of noise. The Custom water setup on the other hand is silent.

I did have capacity yes but I wanted to stay below 1.4 v which Intel recommends as maximum.

8 pack staying within the limits unheard of you can do it 8 pack blow the crap out of that chip lol

Out of interest, re your "binning" process..

Does this mean that if you buy a system from OCUK, if its not an 8pack system then you are highly likely to get a rejected chip, so no chance of getting a super duper clocker? And conversely if it is an 8pack system, you are 100% certain to?!

EDIT

Just read the whole thread so can see whats going on, not sure what to think to be honest.. Wont affect me as I would not buy a pre assembled system. However if I was going to I may ask for no CPU to be installed and ask for a retail box, as if this binning process is in play and you dont go high end you are getting a lower "grade" chip... Point taken, they are all the same to a point, but the silicon lottery element is gone..

LtMatt · 18 Apr 2013 at 08:54

Good results 8pack thanks for posting.

GodAtum · 24 Apr 2013 at 16:42

Thanks for posting, looks like the H100i is not really worth it. How can a custom cooler run quitter when it uses fans?

Again re-read the thread it is not how it works, yes 8 pack tests a handful or so of the oem chips and he takes what he finds to be the best suited for his needs and clocks. The ones he doesnt use are not inferior they are the same chips as they would have been anyway, also again only a few get tested ocuk go through hundreds of oem chips they dont test every single one of those it wouldnt be possible. If you buy an oem chip or a retail chip you still have the same chance of getting a good clocker with or without 8 pack doing his own personal testing for his systems. Lastly dont forget the 8 pack systems need the best of the best to achieve the super high clocks his systems will be coming with, unless your pushing 4.8ghz+ on hundreds of pounds of cooling equipment and have 8 packs tuning knowledge and experience even if you do happen to get one of the chips hes tested that didnt make the cut i would be extremely surprised if you could tell, personally if it was me id much prefer an 8 pack tested chip especially if it came with a signed certificate of what the master believes its capable of in the right hands
8 Pack gets a few chips to play with and he picks the first one he finds that will do the clock speed he requires at the voltage he wants and the rest go back in the pot

Can we put this to bed now?
