6850k @ 4.5ghz only hitting 4.4ghz. - Page 2

Hey zed,

Yep settled at 1.29v @ 4.4ghz. Survived 6 hours of Real bench before I wanted to start playing some Overwatch wink.gif I feel very happy with it.

Enjoy your 6800k smile.gif

Thanks for your feedback- not quite sure what's holding you back from hitting that 4.5 but that's a very excellent voltage for 4.4. Enjoy the chip!

I'm very unsure also I would have thought with an expensive board it would have easily ran at the voltage you guys specified.

It will boot at 1.325 and run for awhile in windows however not matter how much voltage I add all the way up to 1.425 it will blue screen.

I'm very happy with how little voltage it requires at 4.4.GHz however I will keep googling and see if there is a reason I can't make that next step

Thank you very much smile.gif

I can't think of any reason, that board should be able to handle it with breeze. Possibly your load temperatures vary from ours?- Have you got the chip under the custom loop yet or is that going to happen at a later date?

Still using the H110I gtx.

Temperatures sit at 73 on 5 cores under load while core 2 hits 85. @ 4.5 1.408V. Would that core 2 be limiting my potential?

I will reseat my cooler tonight to make sure it's seated correctly. When running at 4.4 1.29v that core only runs around 3-5 degrees warmer than the rest.

Customer loop won't be until I get my hands on 2X 1080 TIS early next year smile.gif

It's not uncommon on Broadwell-e to have a core or two significantly warmer than the others, and those temperatures aren't too far off from what the average 6850K at 1.4V does here. Wouldn't hurt to try a reseat but wouldn't be surprised if nothing changes. We could also swap that 6850K out with a different one if you'd like.

It would be a bit of a mission to send my 6850k back for a replacement since I live in Australia and the turn around time would leave me without a PC for a few weeks before a new chip arrived, I'm quite happy to keep this one as it runs at great voltage at 4.4ghz with load temps in the low 60s.

Really appreciate the offer, great customer service and will be recommending your site to friends.

If I had bought one here in Australia knowing my previous overclocking luck I would have got one running at 4.2ghz with 1.4v tongue.gif.

Ah, didn't realize you were international. Let me know when you get that loop together next year- would like to see any differences in temperatures you get, might as well show off some pictures too. wink.gif

Something has to be missing here. 4.4 at voltage is a good chip. 4.5 should totally be doable. Have you tried bumping cache a hair, maybe a bit of SA?

Try running your RAM at JDEC standards instead of XMP. It may be a wild goose chase, but your RAM is technically an overclock, and I have found that overclocking one part of the system can affect the stability of another. I needed a bump to cache voltage when I started overclocking my RAM.

Either way, 4.4 at low voltage is good for the long haul.

What kind of a bump in cache voltage are we talking about here?

I have tested with completely stock settings, no XMP. Only way I have been able to get it through a Cinebench run (Not realbench @ 4.5ghz) is by raising the Input Voltage to 2.05V.

Bit of a bummer but as mentioned previously 4.4 @ 1.29v completely stable for 6 hours + a further 4 hours of gaming is nothing short of great smile.gif.
