Current batch of 2700K's

[the_worrier]

I'm happy with mine!

 

[halohippe]

just get a 2500k and save cash

Just curious if you purchased a CPU and if so did you go with a 2700k?

Yes I bought the 2700K, just need to get my head around what everything means in the UEFI bios on my Asrock extreme4 gen3 board

 

[Doco]

aye im the same with my ME4-Z but getting helpful tips around here

 

[Defy Belief]

Realistically, will you REALLY notice the difference between say, 4.6 to 5.0.

It's not going to struggle with anything at 4.6.

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.

THIS - You can easily get it stable temporarily @ 5Ghz using custom water - but long term it is not recommended as the temps get too high (anything aboe 70Degrees C is too high tbh). I'm running my 2700K @ 4.6Ghz for 24/7 use - works a treat and I see little to no gain from running it over-stressed @ 5Ghz.

reading these comments I might just stick to my 4.6 1.33 overclock then, was just my first build and just itching to see what I could do - result change vcore and multiplier really adventuress eh XD

I have a 2700k retail currently running @4.5GHz 1.3volts cpu-z shows 1.288 idle 1.272 on full load, prime stable 16 hours /IBT 20 runs on max settings temps peaked at 64 on prime(in quite a warm room, heating on ) cooler is antec kuhler 920 custom fan profile and never hits max fan, also have 5 case fans so vgood air flow through my 650D. Got mine to 5.3GHz but needed 1.5volts cpu-z shows 1.496, only run super pi for benching
so not sure about stability, could probably get stable @5GHz but im not happy running 1.5 volts. I run @4.5GHz because I can see no real world benefits from running @5GHz only benching. Remember they all clock different regardless of new or old stock!

We would all like 5.0ghz stable, but you'll probably have to settle for 4.6-4.8.

5.0 is totally possible on all retail chips I've encountered (and I've built 30 overclocked machines here at work that go to at least that).

 

[DamoTourettes]

HOWEVER, we don't run them with HyperThreading or SpeedStep enabled, so temps top out at 60-65 degrees under full load (they're all aircooled). Best volts I've seen for that has been 5.2Ghz @ 1.425 vcore - special chip for sure.

 

[DamoTourettes]

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.

Neg. Usually first batch OEM silicon will clock higher due to Intel wanting people to be impressed with the chips etc, and recommend everyone else to use them.

First batch 2600k's clocked easily to 4.9/5.0 at relatively low volts - general consensus is that they started putting the high clocking 2600's to one side then released them later as 2700k's at a price premium, because just before the 2700k's came out, all the 2600k's were clocking somewhat lower...

...which is what the case was in my experience also.

errr - whats the point in having a 2700k if your going to disable hyperthreading!?!

What board are you using to get to 5ghz? and roughly what setting are you using to achieve that overclock?

Possible 5GHz Overclock is one thing mate. Whether or not it is suitable for 24/7 is your luck of the draw. Too many claiming to get a "easy" 5GHz out of their 2700k's giving the impression that the voltages used are safe for 24/7. Don't quote me on this but it's probably fairly safe to say all 2700k's will hit 5GHz providing the voltage is set high enough.

Go with what OCuk and Intel have stated for 24/7 usage.

I have dont worry, run at 1.33v at my overclock too confident for go any futher for prolonged periods, I've reached 5ghz but its only for around 5 - 10 mins at most - this was just to run the superpi programme to post here - but all I did was up voltage and multiplier, theres a lot of options in my bios so was looking for an easy way to change some other options lol but think im happy with my tinkering atm will leave my cpu be
