I need help finding out if my Intel 4790k batch number indictates a good or weak cpu chip.

Greetings, people, I'm new to this forum, and i'm not sure where to start off on this topic. The question I have is regarding an Intel cpu chip I recently received in the mail for a good deal.
The Batch number I have is X530B436 and it came from vietnam, can someone tell me if i have a good or weak chip and if it is more prone to overheating more?

Also, how do I find out whether I have a Haswell or Devil's Canyon cpu chip variant?

I was also considering getting a good fan for it as well, I will be having this cpu on my mini itx motherboard.

All 4790's are Haswell refresh cpu's;

Thx Synphul.

In terms of the batch numbers I haven't heard much about there being a specifically bad batch. In the past there have been some cpu's where batch or revision was important and one was consistently better than another. Looking through a lot of forums asking similar there also hasn't been much popping up from forums or discussions on overclocking praising a particular batch. Not enough to be noteworthy and though some have said the L4 batch from Malaysia is 'better' it's not an openly accepted or widely advertised theory.

There's enough difference in user error when it comes to installation, difference between motherboards and potential auto 'performance' modes that slightly overclock a cpu, faulty aio coolers or improper aio setup. In essence too many variables involved beyond simply a bad batch number to come to that conclusion.

The only way you can be sure to get a really good chip is to try one of the places who claim to guarantee a cherry picked processor. It's used (obviously) and supposedly pre-tested and verified to be able to hit certain overclocks at lower than typical vcore. Because of this 'binning' done by people they charge for it and sell it for a premium price above retail. I can't vouch for how reliable those type of operations are so consider it at your own risk.

Devil's canyon refers to the haswell refresh K series cpu's, the 4790k and 4690k. The other non k cpu's are simply haswell refresh that were a second iteration of haswell. For instance, the 4770 and 4770k would be haswell, 4790 is haswell refresh and 4790k is devil's canyon.

Very insightful info, I will keep this in mind, thanks.
