Single stage - Basic noob settings

[suzuki]

Hey guys, so i bought a ss unit and cannot find settings to make my 7700k a good bencher over 1.45v .

So far what i managed to obtain on Apex 9 and 1.43v it’s only 5700 mhz cb15 stable.

Can you share what voltages/settings you use to maximize your freq as from this point doesn’t scale anymore even if i push 1.6v in it.

According to my experience on Apex boards you need to play with pll termination voltage and pll brandwith. If you find good combination you will gain best case a couple hundred mhz compared to auto. I would start with level1 and 1.40v range with SS once youre on cold. You can refer to the asus skylake ln2 oc guide, recommended steps are still similar on coffee lake.

Good luck Theodore.

Nothing you can do, temperature limit. Chip will take more volts and give you more freq once you go lower on temp.

Try going lower in voltage to get more speed on single stage, use LLC over vcore.

Can you explain in detail how you can do that ?

How come others play with voltages of 1.7v on ambient cooling ,i cannot gain even 50 mhz after 5.7 on 4c/8 or 5.9 2c same voltages@1.45v.

I feel bad knowing that there is still plenty of headroom ,voltage wise ,and my ss even in load stays ~60’s.

[FUGGER]

Right now you are at the end of your coolers capacity and vcore is not your friend.

Set LLC to 5, run CB and back off a little on vcore until your lowest vcore is found, now step up multi and bring up vcore ever so slightly or change LLC to stronger value.

Because their chips are different ofc. Alex@ro is correct, you need lower temps to scale more. My 4770K, 7350K & 8700K do the same, 2C 1.425-1.45V max on -20c chilled coolant and 1.55V max on Dice (haven't done dice with 8700k).

Both the 4770K & 7350K have done 6.5G+ on LN2 for what it's worth (@ 1.6V & 1.87V respectively). So it doesn't mean you have a bad chip it just needs to be colder to get more out of it.

Almost done 5800 with same voltage. 

I think i got the trick,will update soon,meanwhile an idle temp from my unit made by @Nachtfalke and tuned for 400w load.

Maximum of the cooling.
You can use slow mode between benches for those hard to reach higher clocks.
In other words you let the SS regain it's maximum capacity instead of rerunning the bench straight away.

Although the SS says your temps are in the -60° C this doesn't mean the chip is getting these temps.
There is a difference between these. To measure this you could put a probe on the IHS.
This will give you more info about the delta and the voltages you alter.

I don’t think slow mode is needed cause it takes max 4 degrees between runs and it recovers them fast :).

Will try with other cpus soon after i finish at least a couple of test with this cpu.

[suzuki]

Solved the problem :).

Thanks to all who posted.

What did you change?

[suzuki]

Another tim on both die and ihs.

Voltages are the same as i used on my wc setup.

It turns out it is indeed a temp limit after all,at least in this case.

[GeorgeStorm]

What TIM were you using?

 

[suzuki]

Grizzly on both die and between ihs and evap.
