Love to see the chip in the OC chart though. Could post the required info for it?

Boxed it in the clamshell plastic. Its going back to Intel and I need my (usable) PC back.
Even at stock during the diagnostic process with XTU testing I was having issues with the chip cooking for brief moments.
Some regular applications like firefox with script/adblock (single threaded) were generating enough temperature ramps causing it to quit or exhibit erratic behaviour.



Its likely a combination of both poorer silicon lottery and the TIM/silicone gasket issue than a dud chip per se.
Though it didn't meet the rated spec when this sample was released as a 7700K SKU.

My cooling solution:
H80i V2 with Dual Servo AP-15 2150 static pressure fans that brings it to Noctua D15 levels of heat dissipation or mildly better.

Late edit: added pic if it matters but I don't think the info will be useful. .

It seems like that my OC will have to wait because Amazon is incompetent as my cooler is still not dispatched after 9 days and customer support is saying that it might be out of stock. Interestingly they had 6 in stock when I placed my order. On a sidenote, Gigabyte screwes me over by not honouring my warranty because the GPU was not sold by their hungarian distributor.

Going to try for 49 on cache. Left RB running this morning. Hopefully all is good when I get back home. biggrin.gif

Gigabyte goes by the S/N in the USA.

Well if I had to add on with the phenomenon that people aren't charting the potato Kabylakes, it takes effort to do so as well. In my case it wasn't worth the effort.

Adding on to the discussion that the chart seems overly-competitive than better sampling (like with the Skylake thread).
It might help if there's a secondary chart for highlighting potatoes without listing reqs.
Or perhaps, just cinebench R15 + CPU-Z voltage screenies for quick and dirty numbers for potatoes.

I don't understand why it's not worth the effort. Whether you do well or not has no bearing on whether providing statistics is worth it or not.

The point of verification and standards is so we don't get overly high overclocks that are not remotely stable. It was to bring clocks down. I don't know what I can do to remove the incentive for people to want to compete with others.

Well, having the top frequencies at the top of the chart doesn't help much in that regard. Maybe sort by core voltage (high->low or low->high) instead?

I kind of agree it would be nice to have maybe a separate chart for quick and easy cinebench runs- could get more people posting.

The good part about cinebench is it takes just a minute or 2 per run.

And as most of us know, these CPUs including Skylake/Kabylake do have a "slow mode" operation (usually undervoltage) where they'd score/perform about 100MHz less than they normally would. Cinebench picks this up in under 2 minutes. (i.e. a 4.9GHz scoring like a 4.8GHz).
The takeaway with such a chart isn't stability, but "Voltage for optimal performance" for keeping track of even chips at the bottom 25 percentile that aren't usually charted imo.

Would be a nice data point to have, for users who can interpret the scores correctly. I think scracy made some good points on the competition issue as well. smile.gif
