New to overcloking need your help

post #1 of 11
Thread Starter 
Hey guys before 1 weak I built my skylake build with asus hero VIII+i7 6700k+ddr4 2666 g.skill ripjaws V.
I managed to oc 4.4 ghz with 1.267 manual voltage(llc 5,cpu cache ratio 41) .I know its a good voltage for 24/7 use but some times I just surf at the Internet and not doing much cpu intesive stuff .Do you think its worth it to go for adaptive voltage?Is it safe ?Because I read that sometimes adaptive overvoltages the cpu.
Also with stock settings with xmp disabled my vcore when is idle is about 0.88 average which is perfect but when I play games and stuff like that vcore goes up to 1.4-5 with average of 1.37 which is way to high with stock settings.
The strange thing is when I enable xmp my vcore is all time 1.245 and some times dropping to 1.2 .Can I somehow lower the idle voltage with xmp enabled with a bios option?Asus epu power managment is disabled.Should I enable it?

Adaptive voltage is a great feature and entirely safe and compatible with OCing.

All you have to do is work out your manual voltage for any given OC (which you have done) and transfer this to adaptive voltage.

Set XMP first to get RAM up to rated speed and then set up adaptive voltage

Example screen shot

Set offset sign to +, ofset value leave auto, enter your manual voltage value in Aditional Turbo mode.....field.

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 75

Just make sure you have speedstep enabled and the windows power plan is set to Balanced or if set to Performance...make sure Minimum Processor State (edit option within power plan) is set to something like 10%

Then you should see CPU downclocking and downvolting at idle and ramping up to max turbo when you need it at your set voltage...

Leave epu power saving stuff disabled would be my advice...you are OCing for performance that costs a bit in power....Speedstep already has you covered for power saving...

Also with manual voltage I changed llc ->5 ,cpu core/cache current limit max 255.50,min/max cpu cache ratio->41.Should I keep also that values with adaptive or should I only change what u told me?Thanks for the help man !!!

You can keep those values no problem....

LLC I like to fix too... so there is not much variation.

The cache min I would leave auto and set whatever you like/works (41) in this case for max

Hey I tried what u wrote at the your first post(1.267 turbo voltage).My idle voltage was about 1.12-1.2 but my max voltage was 1.280.Should I put lower value to turbo voltage?

That idle voltage does not sound right to me....is XMP setting strap 125 or something like that? adaptive does not work on 125 strap afaik

I noticed that without xmp my voltage goes under 1 when idle but when load its goes up to 1.4-1.45.My cpu vid is very high.With xmp enabled voltage is 1.2-1.245 with average 1.23 with stock settings.

That sounds to me like the XMP profile has set strap 125 and that the voltage is staying more or less the same...i.e. speedstep is not working...only varying slightly with LLC and dynamic use by CPU.

If you set your RAM up manually not XMP (setting RAM speed, primary timings, and RAM voltage) using 100 BCLK then Adaptive would swing you between real idle voltage and turbo voltage you set...1.267 in this case...

Thanks for the help.I dont know how to set up manually my ram.I am complete new to oc.I should look a guide and then I will report back.Is is bad to leave it on manual mode with 1.267?Is it gonna reduce a lot my cpu lifetime?Also speedstep isnt downclocking clocks when idle?This is working for me.Should it also lower the voltage when idle?My ram->F4-2666C15D-8GVR gskill ripjaws V

Also with defaults stock settings my vcore goes up to 1.45 LOL.Also cpu-z is reporting 100.5 Mhz bus speed.How is this possible?
