5.1 no gain

[jones177]

This morning I decided to go 5.1mhz on all cores with my i7 8086k.

I did it with my first i7 8086k but since I was getting the frames I want with 5ghz on all cores and was not bottlenecking the GTX 1080 ti I used at the time I stayed with 5ghz.

 

Temps seem fine and I am running stress test now but there is no gain.

My Cinebench number are about the same. My TimeSpy numbers are slightly lower.

 

What am I missing?

Did you disable all power saving and safety features on BIOS? let the chip suck as much electricity it possible can.

 

Also change BCLK to 100.1

I changed the BCLK to 100.1. The Cinebench score is now 1642 so a slight gain.

 

I used this video for setting the bios when I got the Hero board so power is maxed.

 

 

Thanks.

there must be some restrictions from your motherboard, you need to check your bios for limits and change them for further power usage, or you did not apply thermal paste like this guy lmao

Did you set max current limit?

what's the theory behind this?

Should i do this with my 8700K?

There is no heat issue. It runs cool.

Running Cinebench it tops out at 84c.

Long and short duration package set to 4095.

My Cinebench single core score went up from 218 with 5ghz to 222 with 5.1ghz. 

 

I used this video to take a few settings off auto and set to manual.

I still need to work on multi core scores.

 

It looks like going past 5ghz requires more than just casual overclocking skills.

The higher your multiplier like in his case 51 the more likely you'll see base clock fluctuation to under 100mhz, like he was seeing his base clock on the 99.95 margin, from experience it can get as low as 99.80~99.85 during all cores stressing, so the way around the issue is to force through bios an operating base clock higher than the default, in this case 100.1mhz was solely to keep things stable while ensuring you're getting that 5100mhz core clock from the 51x multiplier.

 

However once you find your hard limit on the multiplier say 52 as in 53 will crash, the only other way to try squeezing a little more frequency out of it and get a bit closer to the 5.3ghz it crashes but without crashing is going for a half way through the BCLK, like 101mhz for instance and then run at 5252mhz all cores.

Personally, I found on my 8700k that while 5.1 was achievable, the amount extra voltage over 5.0 didn't warrant the gains (over 1.4v) and there was no appreciable difference between 5.0 and 5.1 even in tasks that I knew were highly CPU dependant.

 

Dialed it down to 5ghz and it satisfied both my epeen and my usage needs.

 

I'd suggest you consider the same, personally.

This all started for me when I added 8xAA to my Ultra/Extreme Heaven 1080p test setup to test for bottlenecks with the 2080 ti. I don't get a bottleneck with no AA and 4xAA but I do with 8xAA. I was hoping I could break the bottleneck with 5.1. It is kind of silly since I play at 3840 X 1600. 

 

I did run some game benches today and I can safely say the I had a no frame rate improvement. I got good temps though.

Back to 5ghz.
