About a month of use. It is an upper 50% in OC ability, based upon the methodology found from tests conducted by ASUS on many 4770k processors. Basically, it's in the "not bad" range of the silicon lottery. It should be able to push 4.5-4.6GHz with more voltage, should you choose to try.

I currently have the processor running stable at 4.3GHz and 1.2v constant.

The price is 365.00 USD. I will only accept PayPal. I will ship anywhere in the continental U.S. and perhaps Canada, via USPS. Shipping will not cost extra. You will have 10 business days to request a return if you have any problems (mon-fri). I will refund your money upon receiving the item. In that event, you pay return postage. Item ships from Fairfield, OH.

Should you wish to purchase the item, please reply here and PM me a PayPal verified email address for me to send the invoice to.

This was my first attempt at lapping and delidding, and while the result was not as pretty as I may have hoped, it was quite effective. The CPU is running MUCH cooler than before. Prior to the modifications, it was at 89C after only two minutes in Prime95. Afterwards, ten minutes in only brought it to 68C.

The lapping is not to a mirror finish. It was simply enough to flatten it out. You may also notice some teeth marks from the vice on the sides of the IHS. I lapped it a bit more after that to make sure nothing was protruding from the sides after that happened. I got a better vice for future delidding, but this is purely cosmetic, as the temperature drop was still significant, at about 20C.

This includes the original packaging for both the motherboard and processor, as well as the intel cooler. The processor will be in the motherboard's socket, since the IHS is now loose and held on by the bracket. I used Coollaboratory Liquid Pro on the die, and this is what I suggest using on the IHS as well.

Without an aftermarket cooler, I'm unsure how the temperatures will look with the delid. Regardless, I'd have to say I wouldn't recommend it. In other words, you'll need an aftermarket cooler. I used a Corsair H60 in my tests, and I'd say something in that ballpark is good enough. A CM Hyper 212 EVO is, as always, the go-to recommendation.

Basically, this is a great chip for running 24/7 at cool temperatures and a moderate overclock. It is by no means a golden chip (in fact, I replaced it with one of those...), but it is a solid chip.

Here is the beginning of the lapping process, for the CPU info...




And here is the finished product...


The part on the left that has a visible line is residue left over from IC Diamond thermal compound.

Finally, thermal results. Keep in mind your results will vary based on many factors, such as thermal paste application, cooler used, case ventilation, and ambient temperature. First up, merely 2 minutes of Prime95...


And post-delid, 10 minutes...

I have multiple times. The price is already at a $45 loss for me. You will not find this CPU this cheap anywhere.

Bottom of original post.

I'd buy it if It could be shipped to melbourne, australia for that price.
February 24, 2014 4:31:49 AM

It looks like that would cost around $85. I included free shipping for the U.S. because it would only be $15 at most. I could meet you about halfway and do $35 shipping.
February 24, 2014 4:43:46 AM

That's really stretching my budget but then again that is so much cheaper than what it costs for those parts here, so $400 total?

How come the maximum temp values are so high?
February 25, 2014 5:09:25 AM

I was running a full stress test at 4.3 GHz on a Haswell CPU with a mid-range cooler. They get pretty hot. That was the reason for the modification.
