immediately apologize for my English. I'm from Russia I bought ivy bridge processor Intel Core i5-3570K but it works incorrectly on my motherboard Gigabyte GA-Z68X-UD4-B3
overclocking not working on it? maximum multiplier 38 but eventually he works 36
this party is defective? or I have an engineering sample? photo: http://i042.radikal.ru/1203/24/ba179bc3c977.png
in Russia where there were lot of these processors? whether to return it back to the store
or my processor will work like everyone else. where to begin mass sales
The Intel ivy bridge processors have not been released yet.
So it seems you have either a counterfeit processor or an engineering sample processor, I would suggest contacting the place of purchase for refund or exchange.
In order to determine if you have an engineering sample processor, check on top of the processor if it says “Intel Confidential” or Engineering Sample (ES).
Doesn't look like an engineering sample to me, nor counterfeit. On some Z68 motherboards, the multiplier is stuck at 38 max. Z77 motherboards will allow you to overclock past 3.8. Z68 will be able to eventually come new BIOS updates.
