What would you guys call acceptable for 24/7 clocks, voltages and temps all-core?

I delidded and direct die cooled the 10900KF now with Liquid Ultra under water which got me like a 12-14c boost over lapped IHS.

Now I can do 5.2/4.9 all core AVX0 with 1.344v in stead of 1.365v. Which is nice. Prime95 AVX FMA3 small fft stable around 80-83c across the cores.

So, I wanted to push for 5.3Ghz all core. But, here's the problem. This chip has quite the voltage wall around 5.2 unfortunately so to be able to get even close to 5.3Ghz AVX0 I'd have to push way above 1.40v. I tried it quickly with 1.448v and even tho it seems stable it runs like 95-98c in Prime95 AVX Small.

Everything under 5.5ghz isn't acceptable for me :)

I don't do Prime 95 with mainstream cpu's. I use them for gaming only :)


1.38v load @ 5.5ghz in games like BF V. SP87 Direct die cooled with Supercool Computer direct die cooler.

I mean, it's not like I use Prime95 for anything but it's a very nice worst-case test for a CPU. If it can handle half an hour of Prime95 AVX FMA3 small fft it can handle anything lol.

So far I'm at 1.435v for 5.3Ghz all core (VCC Sense) at about 90-92c. It should be fine here. I'll game on it a bit.

EDIT: It's solid at 5.3Ghz all core 4.9Ghz cache @ 1.435v. Survived all matter of different Prime95 AVX, FMA3 and non-AVX tests and a few raids on Division 2. Max temps in Prime95 AVX 93c, in Division 2 (and Cyberpunk) 63c.

24/7? Any load voltage of 1.3v or lower is great for 24/7. Clocks don't matter whatsoever, that's based on your lottery. If you can do 6 ghz at 1.3v stable (yeah, right), why not? What matters is voltage (current) and heat.

With 10 second boot times or multiple ways to change v/f in windows these days, really no need to yeet the voltages if you aren't benching or need every bit of FPS from a CPU limited game or app.

Load voltage at 5.3 measured with a DMM on the DMM ports of my board is about 1.36-1.38v on 5.3Ghz and it's stable so far after an evening of gaming.

my poor boy is running at 1.4v (isl69269 reading//vcc or die sense) in games lol.
it will drop to 1.36v when stressing by prime95.

i want the voltage in games lower (like 1.36v) while having the same level of voltage in prime95 (1.36v) plus having some vdroop for stability.

Prime avx is such a unrealistic test if you only plan to game. How much voltage do you require for 2 hour of realbench 2.56 and what are your temps running it?

What type cpu block and rad size are you using? I replaced my motherboard standoffs with some m4 threaded bolts that way my block makes good contact with the die. My temps stay under 70 @ 5.4 and 1.385v but I only test with realbench. I just wonder how good your contact is, you said you had trouble with high temps on ur first mount.
Have you took apart & cleaned your cpu block recently? A clogged block really hurts temps.

VCC Sense (software) is 1.435v in idle condition, 1.406v under AVX load, 1.390v under non AVX load.
DMM is about 0.03v under all these software readings.

So yeah, I am lol. I can do 5.2/4.9 on much nicer voltages but I didn't Delid and direct die this thing with water to not push it to the absolute limit.

@Placekicker19 I run a EK Supremacy with a Coolstream SE 280 and a DDC in a "pre-build" kit by EK (EK Phoenix 280).

It's very old, 3-4 years now, never cleaned internally, only replaced fluid once or twice with Demi water and a bit of car coolant and flushed it.

It is lapped flat copper mirror finish polished and all.

The mount I'm using is the stock EK mount with the Rockitcool washers and it does seem to work but pressure is quite weak, it barely has 0.2mm or so till it touches the standoffs so it can't ever have much pressure. Then again, the CLU spread is very nice and temps are so even across the cores I doubt the mount is bad.

I am going full new custom loop as soon as I can get a 3080 with 3x8 pin and a block for that. That would be a HWLabs Nemesis GTS 420 + 280 in push pull so I can keep it all with 140mm fans, a random D5 of course with probably a EK res and a Bitspower Premium Summit M Mystic Black block because that block is absolutely beautiful.

The stock ek supremacy evo standoffs worked good for my 9900k direct die, however the 10900k die is much shorter and they were a hair to tall at providing proper die contact.
You should see huge improvements with another rad and that new block. I bet your current block is quite dirty too if its never been cleaned internally. The water channels are so small it doesnt take much to gunk it up and have a negative effect on temperatures. Evga finally contacted me for the rtx 3090 ftw I preordered back at launch, but seeing the kingpin has released, is only a couple hundred more, and comes with a 360mm aio I just couldnt pull the trigger on the ftw. I dont even game much, the last game i played was witcher 3, it came out on my bday and I had the 980ti at the time. I go through gaming phases in life, ill game alot for a few years and then go maybe 5 years without playing one game. I do like playing online poker through and its important to have a fast pc when you have many tables up.

I'm done testing for now with the chip. I really should upgrade the loop and block.. you're right. Might just order the block, pump and a 420 Nemesis GTS soon and expand it later for the GPU once I get a proper block for that.

10900KF Delid + Direct Die (Rockitcool frame) batch# X032G247.

5.0 on 1.210v, 5.1 on 1.272v, 5.2 on 1.334v and 5.3 on 1.390v. 1 hour Prime95 non-AVX small fft measured and tested.

All tests done with a MSI Z490 Ace, BIOS 12.W BETA, 4.9Ghz cache, 4400C17 RAM, 1.40v SA 1.35v IO, LLC3, Mode_1 Lite Load, 700Mhz switching frequencies for the MOSFET's. C-States disabled, TVB disabled, speed shift disabled, EIST enabled, Turbo and enhanced turbo enabled. Windows power plan Balanced with idle clocks enabled.

For AVX stability I need about 0.02-0.03v more for all voltages and frequencies.

All voltages are VCC Sense through software (HWINFO64). MSI Z490 Ace board.

Just in case someone wants to compare batches or something.

I am now daily driving 5.3/4.9 and temps are great. 90c hottest core Prime95 AVX FMA3 small fft after 1h, 82c non AVX.

In gaming I've seen it hit 67c, in benchmarks like 3DMark and Cinebench it hits about 77-78c. Fans only ramp up above 75c so this is still with barely any fanspeed on the rad. In games the fans just stay at idle 900 RPM.

Seems like a great CPU to me even tho it needs quite a bit of juice. Cache is strong, IMC is quite strong with enough IO/SA and handles 32GB DR B-Die at 4533Mhz just fine (4400 daily). It's relatively well behaved cooling wise after the direct die mod as well. I like it ☺

Is sp48 possible on a 10900k? This is what I have lol. I checked on updated bios on a z590 Strix A and a z490 strix E and Both showed sp48 (the Z490 Strix E had 87 but it was old May 2020 bios, after updating to Dec Bios it showed 48). I only checked SP on the Z490 Strix E as I borrowed the board. Currently have it in the z590 strix A.

here is the VF curve which doesn’t seem that bad does it? On the Asus it doesn’t seem to overclock very well.

Also Vcore doesn't seem to show properly on the Z590 Strix A in hwinfo. Doesn't ever seem to go higher than 0.746V, same with CPU-Z

F2CB5369-0C64-442B-B821-E832118A7C69.jpeg

Additional information.

Z590 auto seems to want to enable MCE by default rather than the F1 F3 when a new CPU is installed on Z490 asking to use Intel spec or not. I left it on Auto, optimized defaults.

VID on optimized defaults, which I think MCE is auto on.. (all auto, no ram OC etc.) - it bounces the CPU around from 4.9-5.1Ghz all core just sitting at desktop idling.
Z590 A Strix - Auto optimized defaults.png

Average VID was 1.25-1.26V when it was bouncing around

When I set sync all core 5.0Ghz everything else on auto I see average 1.37V with min 1.36V for VID.

When I set all core 5.1Ghz everything on auto, I see average 1.415V, min 1.38V.

edit disabled MCE in BIOS to enforce stock limits. here are results:

Auto clocks still bounce from around 4.9-5.1
VID: min 1.19-1.203V; max is 1.299-1.31V

Sync all cores to 5.0Ghz MCE OFF:
VID: min: 1.345-1.352V; max 1.389V - 1.4V

All cores 5.1Ghz MCE OFF:
VID: min 1.40 -1.404V max 1.415-1.42V

Hope this helps. Thanks in advance.

This is what an SP 59 V/F curve looks like, so I got bad news for you:

Thanks. Maybe I don’t understand fully. Is SP based off VID @5.3Ghz? Because my VF curve up to 5.2Ghz seems to have a lower VID compared to that SP59 you shared? I mean I’m not aiming for 5.3Ghz but **** even 5.1Ghz would be nice I’m not sure where I sit for that.

That's what seems to be the deciding factor, the VID at 5.3. I noticed all other points were lower for you as well. Contrast with an 81:

Just being able to run prime 95 small avx @5.3ghz is a accomplishment. What kind of amps/wattage are you pulling during it. You just wanna be careful about running a high amp load like that for any extended period.

It's the first and last time I'm going to do that, just wanted to be sure it can handle any AVX load I might some day throw at it. I know it's risky on modern architectures.

Wattage around 335-340w btw so about 240-244 amps.

Never doing that again that's for sure lol. But, it stayed under 95c throttling limit. So far I've been gaming, benching 3DMark Time Spy and playing around with FL Studio a bit building some hardstyle like I used to do 5 years ago and it's solid. Zero issues so far and temps are great. Max I've seen rendering is 72c without the fans ramping up, 3DMark CPU test got to 77c with a slight increase in fan speeds but it seems happy here.
