Skylake Overclocking Guide [With Statistics] - Page 773

post #7721 of 11361
I can't seem to get the block level test 6 stable with MEMtest 86 beyond 2666MHz frequency using 4x16GB DIMM's, but 2x16GB at 3200MHz seems to work flawlessly. Wonder if that's a motherboard issue with my budget ASRock Z170 Pro4S motherboard or i3-6100 IMC related one. Ideally it's just a settings issue, but I've had no luck with it so far what's the max safe VCCSA and VCCIO voltages I should try?

There are also a few settings I'm unsure of in the bios should ASPM support settings for PCIe/PCH/DMI/PCH DMI be enabled or disabled ideally for overclocking and should I keep Write_Early_ODT enabled or disabled for performance/stability?

Kind of curious if it's important or not if tREFIx9 divides evenly with tREFI or not for example is tREFI 65535 vs tREFI 65532 more optimal with tREFIx9 127? tREFI 65532 divides evenly while the former does not.

Ram is only 2166mhz...
Nope. Not required. You mean 2133 Mhz?

Hi everybody,
I don't have any skills about overclocking. And I am getting confuse with some parameters.
What I read here, lot of users have good expierence.

I want to share a youtube video with some settings. I have the same motherboard and processor. Can someone confirmed if this are a good starting point?

THank you!

well I can get 4.8ghz @ 1.34v on a 6600k. so Yeah I'd say your chip isn't that good thumb.gif

What LLC are you guys using on Asus Maximus motherboard and any other CPU settings you have changed in the BIOS such as power phase etc?
post #7727 of 11361
Hello, I need advices, this is my setup

- ASRock Z170 Extreme 4 (latest bios)
- Intel i5-6600K
- G.Skill Ripjaws V DDR4 2400 C14
- Cooler Master Evo 212X (European version)
- PSU XFX TS 650 Gold

My results are:

4500 MHz
- (Prime 28.9 FFT) stable at 1.29V with FAN @ 100%
- (Prime 28.9 FFT) stable at 1.32V with FAN dinamic (very silent while gaming etc etc...)
For this reason it seems that overclock is also TEMPERATURE related (over 70-72° stability is compromised).
LLC is set to 3, and there is no VDrop at all under load.
EVERY power saving feature is disabled (both BIOS and Windows)

4600 MHz I need 1.36V or more but it makes too much heat with Prime 95 Small FFT headscratch.gif
The second CORE is the weakest one (the first that crashes)
Any suggestion? Maybe I could play with other voltage settings rolleyes.gif but it seems my CPU is just average...

Could I reach 4.7GHz @ 1.4-1.42 V with delidding?

Thanks

Double post sorry :-D

x264 not Prime, yes Intel CPUs start to lose stability faster when over 70C reported.

212X is a crappy cooler for OC. It doesn't have the necessary cooling capacity.

After delid it is likely you will hit the 4.7 mark. The reduction of temps will be in the range of 10C and will likely allow you to maintain stability at the higher clock. With that said however use X264 to stress the higher clock. You may find it is actually stable but the heat generated with prime is causing it to appear unstable under that test. I would venture to say it is unlikely you will ever experience a prime style load so being stable under x264 is likely stable 24/7.
