10850k overclock

[raul_16nic]

Max stable overclock is @4.9ghz on all cores.It's better than stock?

 

[dgianstefani]

No. You are gaining 100mhz multi but losing 300mhz single.

 

[raul_16nic]

If i run bios default the votage is to big and in games it's sit only @4.8 ghz on all core.

Actually yes... I have a 10850K and 4.9 GHz all core is better/generally faster when I tried it vs stock in games.

If you maxboost / unlock then OC and autovolt on the motherboard your temps will be insane.

Some tips for overclocking:
1. Use adaptive voltage with an offset.
2. Mine is stable at 5.1 1.34V, you can set "allow TVB ratio clipping" in the bios, that will drop you to 50x @ 1.29V when above 70C-75C and all cores are firing,
3. Set Motherboard Thermal Limit to 90C that will drop you to 49x 1.26v and continue dropping (I've never seen below 49x even during extreme avx spikes)

That will allow you to run at 5.1 most all of the time on all cores, dropping to 5.0 for workstation crunching (or playing cinebench ) and then absolute stop at 90C at 4.9 for extreme scenarios (or your cooling fails or whatever).

U can use this method for a 4.9ghz all-core as well... that way you don't have to worry about temps.

It's unlikely it's only stable at 4.9ghz since it can boost to 5.2 -- likely cache settings or temps are limiting your OC.

So the solution to that is instead of losing 300mhz single you lose 200mhz?

Just manually set the voltage to 1.3 and OC to 5.0 all core.

Anything below 5.0 all core is 2018 level performance. 7700k and 8700k all can do 5.0 all core, 5.1/5.2 is more realistically achievable with good cooling on 9th and 10th gen chips.

The point of intel chips is single core performance, and good enough multi. If you do an all core OC of 4.8 and lose 10% single, or have max clocks lower than 5.0, you might as well just buy a ryzen.

The issue is that if you're running a CPU intensive game, then 4.8Ghz is all you will get at stock. Once you leave the game, and are dorking around on TPU, then you will see 5.2ghz on a core for a few seconds. The boost algorithm is not that great for all core load - I'm sure it works in some games, but every modern game I've played will stick at 4.8, so effectively you're just gaining 100 Mhz with the all core.

But I totally agree that he should try to OC higher, it's very unlikely that chip is stuck at 4.9, and a 1.3v 5Ghz blind OC will most likely work without issues.

I have a bad chip.In prime it isn't even stable @4.9ghz.I am thinking to sell and buy or a 10900k or 10600k,10700k.

 

[Zach_01]

If Im not mistaken P95 uses "hard" AVX workloads and no CPU can achieve that on max turbo speed without a truckload of voltage and exotic cooling...

What is a 'truckload' of voltage, and what is 'exotic cooling'?

 

[phanbuey]

Are you sure it's the chip and not your motherboard? What mobo do you have?

 

[dgianstefani]

You bought a 10850k. It's a 10 core that wasn't good enough to be a 10900k. Not really sure why you expect it to run as well as a 10900k, or are surprised when it doesn't OC very well...

 

[FireFox]

and what is 'exotic cooling'?

Something like my previous Build?

 

[GerKNG]

depends on the Motherboard.
my 10850k basically OCs like a potato until it landed on a Unify.

5.1 All Core was easy at 1.36V
before (on a Strix F) i basically was on a wall at 5 Ghz 1.375V

 

[raul_16nic]

I have a asus tuf gaming z490 plus wi fi

 

[phanbuey]

ASUS TUF are good boards, can you post your OC and bios settings? Can you post your temps during p95 HWiNFO?

 

[raul_16nic]

1.32 v llc 6 @4.9

 

[phanbuey]

what is your cache ratio

It's just that chip passes 5.2Ghz (it has to or intel won't let it out the door) - so it would need like 1.5v+ to do this if it is not stable at 1.32v @ 4.9. Every other person i've talked to has been able to hit 5.1 at 1.33-1.36... so it just seems likely something else is causing the p95 errors.

Isn't that only on the preferred core(s) when below 70c?

 

[raul_16nic]

I try cache ratio auto and 4,7 max

 

[phanbuey]

Can you set max to 4,0 for now. and also try for 5.1ghz at 1.34?

Chiller?

I was expecting triple cascade or similar.

 

[raul_16nic]

To try cache ratio to 40 and 5.1 ghz @1.34 or what?>

 

[raul_16nic]

I think to change my motherboard (tuf z490 gaming wifi) and go for de the msi meg z490 ace.I have any chance to get a better overclock for my 10850k and to see any improvements?

Hi,
No
Tuf is a okay board likely better than anything msi has.
10850k is a low bin 10900k bottom line
Most available 10900k's are pretty bad because they are way too voltage hungry which it seems you already have with meager cooling.

I'd personally wait for prices to drop on a 10700k or pop for one now micro center shows 350.us now think they are still too high though.

 

[raul_16nic]

The msi meg ace z490 is a high end motherboard and the tuf is midle range
