I7 2600K Stepping and Overclocking

I've seen advice that we should look for a Sandy Bridge stepping C to maximize the chance of a good overclock. Is that correct? How can I identify the stepping from the markings on the box or on the chip? Thanks.

I haven't heard anything about a new stepping. As far as I have seen, D2 is the one and only stepping available. Batch number might make a difference though. My 2500K overclocks to 4.8GHz stable, and I'm happy with that. You have to get very lucky to get higher than that.

I answered your question in your own thread. Please don't ask the same question in other peoples' threads. It's bad manners.

I have found that the new sandy bridge is alot easyer to overclock then the older modles. Every I5 and I7 comes with it. There is no special markings on the box. The highest i have gotten for I7-2600K was 5.2Ghz but brought it down to 4.1GHz till they fixed the motherboard problem

Actually, you guys are talking about the C batch, not C stepping. The C batches are still D2 stepping.

The Batch number is on the official Intel sticker on the box. Mine is L047B217, a "B" batch.

sorry i was talking about c Batch,my bad
i figured OP was asking about batch since the chips only came out a month ago it will take 4~5 months before you start hearing about a new revision

What's the max speed that you can overclock at least most 2600Ks?

Average is probably 4.6GHz.

Hey guys... so I have seen on eBay someone selling Engineering Samples with D0 stepping. I didn't know weither that was legit or not. Price is at a premium and claims to do 5.1Ghz

From the reviews I've seen the Engineering Samples are D1 stepping. Whoever put them up probably is confused or it's a typo.

All retail chips as of now are D2 stepping.

Correct all engie samples are D1 stepping.

Just a guess, but the second one (the B batch one) is probably more likely to overclock higher. Unfortunately, you don't have one of the C batch ones, which seem to overclock higher with less voltage.
