What's with the pre binned i9 9900k processors

Ohhh it’s an OEM cpu.. I see! Mine will be an OEM 9900k I guess..I hope it’ll do 5ghz

Yes, it's an OEM CPU. They're sometimes called "tray" CPU's because they arrive in bulk in trays.

When I worked as a PC engineer/builder etc in the late 90's I used to speed bin a few trays for fun during my dinner break (it was a lot simpler then - change the bus speed jumper, see if it ran at default volts. :)). For some reason I've kept one of the empty trays:

How quickly can you put it in the bin? :p
 
Not this again... and again and again .. Dear me... Stop typing this stuff on here.....

We don't return any binned chips to website stock we have said this sooooooooo many times now.......

To the OP these cpus are delided also for better by 8c - 15c perf than Intels 'soldering' we lap the die and ihs too and retest with several stability tests..... It's seriously not a 5 min job... Before writing such nonsense try to understand the process....


Hi Ian, do you have a set thickness you lap the die too??? are you able to share the thickness??

Geek :).
Serious question. How did you speed bin them so quickly? I have this image of having to apply paste, put cooler on and clean up etc - all delicate actions.

As above really although we rarely used heatsinks with Delta fans, just run of the mill low amperage fans that came with the basic coolers (our builds were typically for schools, colleges and businesses).

We didn't use paste back then either. The heatsinks had a small square of TIM on the underside from the factory. The heatsinks were also very small compared to today and had such a relatively weak spring mounting system they were very easy to install or remove in a couple of seconds.

And yes, 25 year old me, fresh out of retraining at college and having landed my first techie job was definitely a geek. Happy days. :)

I would play it safe & just get retail, unless the OEM is substantially cheaper in which case it maybe worth the risk but usually not the case. I'd always be concerned so would step up to the retail. Good luck.

P.s. I do like the option OCUK have for speed binned chips but their too overpriced. Sometimes when their on offer they are worth considering though too ensure a good one if u don't mind paying a premium.
