Im looking at getting a 2700K soon and am wondering what the current batch is like, any experiences?

Obviously i would like 5ghz stable ;)
 
Hopefully I'l tell you monday when my motherboard arrives XD The batch number of the one I received was costa rica 31st oct-6 nov B (plues other numbers lol)
 
 
Its just your luck, some chips will only do 5ghz with very high volts (like mine) which makes 4.8ghz a more reasonable clock.

5ghz is also only around 5% more speed that 4.8

If you really want higher clocks then i'd recommend waiting for ivy bridge to come out.

Surely 5ghz on these chips is possible watercooled? what you think are my chances gettin it stable with this lot

A couple of things come to mind. Maybe get a more powerful PSU, so it futureproofs your system more. Also, I hear the Sandybridge do overclock well on air/kind of watercooled, like your choice, so it may be possible to get 5ghz. Just bear in mind you are only guaranteed to get the standard speed, anything else is a bonus really. If you don't get 5ghz you will get close I am sure and I doubt 4.6ghz compared to 5.ghz is much different in the real world.

Is there a lot of difference between the "kind of watercooled" and the full watercooling systems?
 
not sure on the retail ones but the OEM ones are very good.i ordered two OEM ones to try and both did 5ghz stable.the first one at 1.4v and the second one at 1.36v so i sold on the 1.4v one.

Well I can't comment from experience with the full water cooling systems,since I have a very similar cooling system as you are looking at. But I am about to get my own water cooling system very soon and read they do make a fair bit of temperature difference and also run quieter too.

If you can keep the temps low, then in theory you should be able to overclock that bit more. For a mid price build I still think you will be fine with that. My Corsair H5O has done the job fine and only now am i wanting to mess with the water cooling side of things. If you want to watch the pennies, have a system that is pretty much maintenance free and still half decent temps, then you will be ok with that. If you want to squeeze every last mhz out of your CPU and also have a quieter and cooler PC, then go down the water cooling route.
 
Could mean two things in my eye,

1) They are all "top quality"
2) They are the first lot to be released, you would expect manufacturing process to improve and get better during a chips life cycle, so the later batches OC better again.
 
My 2700K (one from the first batch that ocuk had) does 5.0 GHz at 1.45V IBT stable (on maximum setting). With air cooling, my maximum without temps in the high 70s was 4.8 GHz, 1.38V). I run a daily overclock of 5.1 GHz at 1.5V (I use chilled water to cool the system, and my maximum temp when folding 24/7 is 54C). That maximum I got for benchmarking was 5.5 GHz (55 x 100). Although I could alter the bclk at low speeds, with high multipliers the bclk can't be altered (at least, I have not managed yet - I might try with my GPU at stock and not folding, and the chiller set to 3C, so I can get maximum cooling for my loop, and see if I can get 5.6 GHz stable on more than one core).

Obviously thing do change between batches, and even between different chips off the same wafer, but I would expect most 2700K to do 5.0 GHz stable if you can keep it cool enough.

There's widespread reports of chip degradation at those kinds of voltages, some report the chip failing quickly too.
 
Basically, if you are very lucky.. the 1 in 10? or the 1 in 20!? you'll have a 2700k that overclocks to 5Ghz @ 1.36v which should be easy enough to keep cool on a custom loop or closed loop system with the fans set to high.

Anything above 1.36v and you'll be pushing close to 70oc which is your voltage/temp wall.

I have my 2700k OC'ed using offset voltage and it needs 1.368v load to run stable at 4.8Ghz. Temps are low 60's under load using IBT. I have a stable 5Ghz profile @ 1.438v but under stress temps are much hotter in the mid 70's. This is on a custom loop.

From my experience and from the other results I've seen you can pretty much expect 4.8Ghz from your 2700k and a possible 5.0Ghz with a huge voltage/temp bump.
