I've got a 10850K, ASRock Z490 Phantom Gaming-ITX/TB3, and NH-D15 with NT-H1 TIM. I can't remember exactly what my settings are, but I'm using stock voltage settings and ASRock follows Intel's reference spec here. I think I switched on multicore enhancement and increased the power limit to 200W sustained.

It'll run at 4.4GHz on all cores indefinitely. Temperature is around 75°C. If you have a good liquid cooler and/or use something like liquid metal and/or delid, then 4.6GHz on all cores is plausible.

Those last few hundred megahertz really hurt though. I need to increase the power limit by 100W to hit 4.8GHz and the cooler just can't handle it. 10% more performance costing 50% more power is pretty typical though once you get near the chip's limits.

 

depends on the silicon. My 10850K needed 1.3v+ for 4.9 and my 10900K only needs 1.26v for 5.1.

yes, you can delid 10th gen.

4.6 is a 200 mhz underclock on the 10850K so I can't imagine you not being able to cool it with an AIO.

 

Hello,

Great ! - Some good feedback !

On Kaby Lake 7700 K I got a big shock before a delid - and "The Pook" here informed that basically with 6th / 7th gen i7 a delid is needed - Which I did on a 6700 K before drowning it accidentally in LM (big mistake - because the "nozzle" wasn't put on the end of the Thermal Grizzly - But I learned fast because it was important.

Then a 7700 K was delidded - and after experimenting with thermal / paste then LM - A great OC was achieved on 7700 K @ 4.9 Ghz with good temps that made me feel happy.

OK, I've read that on 9900 K it is a lot more involving to delid maybe because of a solder that is difficult to remove - But this is where a solder "dissolver" is needed (which I have) - Is this correct?

OK moving onto 10850 K / 10900 K - Will it be the same "hard solder" that would need removing with "solder dissolver" - And if so, if this was done as per the 7700 K, would the temperature results be similar ish ? - OK, 10 cores is more difficult to cool than 4 right? - But would there be a result where the chip would be 20 C cooler (maybe 15 C) just like the 7700 K was?

 

For any type of LM squeezing, I recommend NEVER plunging the plunger, not even a little bit.
What I do is twist it left and right slowly while applying a minimum amount of pressure inwards. That way the twisting creates its own pressure and then the LM will slowly start to form a nice small ball, then you just release the ball on the surface and repeat if you need more.

I haven't had a LM accident since doing that, and I even re-use the kryonaut plunger with homemade Galinstan, so I can use the tip to apply the LM.

 

Hi, Falkenstyne,

I took more care afterwards when the mistake was understood - Then the tip was used and away from the CPU - The little ball you refer to is known as a "euctectic" which is very scientific and I must admit I needed to look it up when this was read about - But the whole process of OC'ing is scientific in nature whether we realise it or not -

 

With the proper delid tool it isn't hard. Rockitcools kit come with solder removal stuff. It is a good idea to heat up the IHS first with a hairdryer or heat gun to loosen it up a bit first tho. Makes it much easier.

A good AIO can handle a 10900K at 5.1-5.2 after a delid just fine if it isn't too bad of a sample. Up to 1.35v is manageable on a EVGA CLC360 and H115i Platinum. Expect 90+ on AVX stress tests anyway but gaming holds up fine.

Mine is terrible, it needs 1.39v for 5.2 all core and direct die liquid metal with a custom loop it runs low 70's in gaming and touches low 80's in for example Cinebench R23 and 3DMark Time Spy / Port Royal.

 

10850K 5.0GHZ on all cores 65C max with custom loop here. Never tried air.

 

Now the 10850K/10900K can be hot.

IF interested Cheap $40 AIO 240MM on normal 10850K with all core 5000Mhz.
All settings BIOS, quick and easy setting shown in video and description with 30Minute AIDA64 stress test and a multi cinebench 20 run.
Highest temperature was 77°C

 

Hi,

All very good input - Thanks -

I'm not hell bent on 5.0 Ghz - On 7700 K it was good @ 4.9 Ghz - So anything from 4.6 Ghz +/- will be fine.

I do have Corsair H150i and have used air coolers - such as Noctura NH-D15 or Dark Rock Pro 4 - etc.......

Is there much difference between a 240 mm AIO vs 360 mm AIO ? - Thanks

 

NH-15 is top of the line air cooler and can compete with AIO,especially if your just going to run 4600Mhz which will not need as much voltage.
240MM vs 360MM would mostly compete on noise level as temperatures would be similar at the settings your going for.

Here is a review of 20+ coolers if you want to look

Hi,

Great replies and helpful - Thanks

I wouldn't go for a top of the tops OC and settle for just a little less but have an easier time in managing the OC! - Be-Quiet Dark Rock Pro 4 is a good air cooler too - Air is better for 24/7 if the temps are good enough and easy enough to manage

 

My 10850k at 5.1 and 4.9 ring would hit 90s looping cinebench. For gaming used to hit 70s max average 60s
