Basic Skylake 6700K Overclocking review and performance.

[new boy]

2.024V core voltage will most probably kill or seriously damage the chip over time

Bit of an understatement

 

[C64]

True for any arch...

Have you been reading Corsair's propaganda?

it's not true for every system for example haswell sees barely no gain using over 1600mhz ram

I caved in and bought i7 6700K. Was on 4790k, Also bought the EVGA Z170 Stinger mini itx board and Phanteks Enthoo Evolv ITX case. My first ITX build. Think I'm going to stay small form factor from now on.

Nick has done 6.9+ I know that.

Yes there is some gains from memory but similar to all other platforms not massive gains.

Why?

I considered it, but it's looking more likely that ill be going X99. 5820k, msi mpower X99 and 16gb of ram. Might keep the 4790k and board and ram to replace my old X58 setup.

 

[Simon Belmont]

Why?

Really wanted to go mini ITX. Didn't really want to buy a z97 ITX board. Had a little extra cash this month. Really wanted new tech to play with

Not tested evga z170. The X99 matx I tested was not great to be honest. Poor mem and cache oc.

 

[opethdisciple]

This is probably the best summation of the 6700k vs 5820k debate I've seen so far.

I wanted the AsusZ170 itx board, but it's not out? The EVGA z170 Stinger was and is the only itx board out for Skylake. Don't really care about overclocking memory. The board looks sweet and small and that's what I wanted.

 

[fa5719]

15% ST is way out in my testing. Not even 10% for me.

For gamers of course high quality card most important. For Gamers who do other things also add X99 and be done!!!

Well - so if I count my 3570K@4700MHz it equals roughly to 4500 Hasswell incl Hasswell refresh it equals roughly to 4200/4300 MHZ Skylake ?

 

[Mr Fujisawa]

I will probably go for skylake more for the motherboard things like usb type C, particuarily the boards which have the Alpine Trail chip, I'd feel more comfortable being future proofed that way. What IS concerning me though is only having 20 lanes, that seems very low and will limit things like pci-e storage.

16 lanes on the CPU, 20 lanes on the Z170 Chipset.
It's fine!

Ah ok that explains things better!

Hi, how do i found out what the stock voltage is on cpu i have 6700k, before i start to overclock it

i get 2 different readings,

in bios i get this



then with power saving off in Bios so doesnt lower cpu speed when idle i get
between 1.296v - 1.312v



then when power saving is on in bios and power management on high performance in windows i get 1.328v



also in bios i looked everywhere i just cannot seem to find where i can change the cpu ratio and doesn't let me change CPU voltage manually, I have a MAXIMUS VIII HERO board

im coming from AMD which i used for years so this is abit new and was quite easy on AMD

i figured out how to change multiplier and cpu voltage, better to use keyboard then the mouse

so how would i start overclocking, i would be happy at 4.5ghz, also do i set the ram manually to 3000mhz with volt and timings or can i go with the xmp, while i overclock cpu ?

THanks

Its about 1.3v on all Skylake chips. Should go straight to 4.5 without any additional volts.

 

[Silent_Scone]

6600k doing 4.6 1.4v and 4.3 uncore. System Agent requirements vary but seems to get a lot steeper once you're in 3400+ territory depending on CPU. Auto rules work fine below this but can be excessive. I only need 1.05v for 3000 8-16GB. 3400 especially if tight can require in excess of 1.25v. Still waiting for UK to get hit with some of the higher binned kits. X99 kits work ok but some will require more voltage than would be needed on x99 due to how certain vendors bin them. I need an extra 20mv on dram on the quad 4x4gb 3000 hyperx on z170.

I also get the same on my 4790k

Motherboard Voltage reading - CPU VCORE - 1.284v - 1.296v
CPU Voltage reading - i7 4790k - VID - 1.275

Someone has managed to get Skylake to 6.8GHz all cores active !

http://www.kitguru.net/components/c...th-all-cores-active-on-msi-titanium-platform/

Did you see what voltage he was using, also he was using Liquid Nitrogen to cool it. So in my opinion it doesn't really mean anything as you can't run it in a computer for everyday use.

 

[skiersteve321]

can someone please link me gaming benchmarks between 6700k at stock at 5820k at 4ghz, why did none of the big reviewers compare the two? seems weird since thats its main competitor, really want to find out since it will prob determine which build i go
