Intel to launch 6 core Coffee Lake-S CPUs & Z370 chipset 5 October 2017

Assuming cooling remains OK - what voltage is OK on the 8700K? 1.45V? Running 5ghz at 1.31V currently I can't decide whether to push it further.
 
Intel's 8th Gen datasheet mentions 1.52v as being the maximum, but to be on the safe side stay well bellow that.
Also be careful with LLC since that will introduce voltage overshoot.

Sticking to <1.4v with LLC 0/Auto for 24/7 is probably a good way to go about it.
 
Anyone got any benchmarks of 8600k OCed vs 2500k @ 4.7+
I'm still running with a 2500k at a conservative 4.6GHz but I'm thinking that it might now be time for an upgrade.

GPU is a 980ti and I mainly play WoW and VR titles on the Rift.

Someone started a thread looking at the difference between a 4670K at 4.3Ghz and 8600K. His chip should be pretty close to yours.

I have a 8600K at 4.9, 1.35v. Max temp 70, games in the 50’s.

This is with a predator 360, anthing in particular you would like benching?
 
TBH, I can't think of anything that would be a sensible comparison at the moment.
I'm more concerned with WoW performance in big raids. My FPS can drop to the 20s at 4k res and this is with my GPU essentially idling at 40%.

Thanks for the link @AndreiD
It's amazing that a 6-year-old CPU is still even on the graph TBH isn't it? It would be like back in the day that the 2500k was released, benchmarking it against a P4 and having the P4 even remotely keep up.

I can't think of a CPU at any point that has had such a long life.

Performance per core has gone nowhere TBH.

You could probably whip the 2500K into a shape. 2133Mhz DDR3 and couple of hundred Mhz on the cores would show some big gains.
 
benchmarks don't tell the whole story.

the only way I would be able to run a 2500k now is to disable speed-step entirely.

for me there is a world of difference between a 2500k system and a Skylake based rig when CPU speed-switching is enabled. With a NVMe drive fitted to the Skylake rig the difference is too large for me to even consider the 2500k based rig as viable but that said I appreciate everyone is different.

Skylake 4.8GHZ to Kabylake 5.2GHZ on the other hand - no perceptible difference and I might be wrong but the Skylake setup felt quicker.
 
So.. 5ghz, and 4000mhz

But won't run AIDA 64 or Cinebench without 1.35 Vcore.
Corsair Platinum 4000mhz in there. The XMP puts the Volts to 1.35 automatically to the memory..
Worth tweaking down?
 
If you are testing with a version of Prime that uses AVX make sure you use an AVX offset otherwise you will be artificially limiting your clock speeds for the vast majority of applications that don't use AVX.
