Intel Core i9-10900K Review

Does anyone have any experience cooling this or a similar chip with low-profile coolers? It's going in a rack so AIO or liquid isn't an option.

Nah, she'll be fine.

It's not really SFF, but I'm pretty sure most posters on here have more experience with SFF cases than rackmount chassis.

Only that 10900K uses over 250W at factory settings so would require a 250W TDP cooling solution running at 100% fan speed.

I ran RealBench for 8 hours and got 1 WHEA error. Is that concerning? Should I continue to go up in core voltage until I get 0 WHEA after 8 hours? Thanks in advance

Intel 10900k MSI Gaming Edge Wifi

CPU ratio: 51 Ring ratio: 43 XMP enabled: DDR4 3600Mhz 16-19-19-39 1.350v

CPU core voltage monitor: VCC sense CPU core voltage mode: Override mode CPU core voltage: 1.365v (1.288v under full load) VCCIO: Auto (1.256v in bios, 1.2v under full load) VCCSA: Auto (1.198v in bios, 1.275 under full load) LLC: 6

CPU package temp: 88-93 under full load Ambient temp: 95 degrees

Drop the voltage, drop the clock to 5GHz. You get less stable with higher temps.

Also try occt, it tends to expose instability quicker.

add more voltage its unstable .
if your barley passing real bench prime 95 will definitely fail
prime 95 needs 0.030 + more voltage then real bench .

if your 1.30v try 1.31 v

I could pass RealBench and Prime95 non AVX for hours without BSOD. I just get 1 WHEA error with prolonged use. I’m trying LLC mode 4 right now

Try dropping VCCIO+VCCSA. Personally I'd try dropping vccio 0.2v and vccsa by 0.03v (off load voltages) should be plenty for dram @ 3600 at those timings. At the very least they're both unnecessarily high and increasing cpu temps.

LLC6 is max? Voltages seam pretty tight. Wouldn't surprise me if your whea is triggered by drop in load/transient response. From my experience, higher the LLC equals substantially increased likeliness of instability issues arising from dropping out of load, rather than instability during load.

LLC mode 6 isn’t max, mode 8 is max. I lowered LLC mode to 5 to see if that helps. I will try lowering vccio and vccsa once I get it to a stable voltage with no whea errors. It seems from lowering the LLC, I’m getting less whea errors already so I hope this works

I’ve said this a lot here and I spend constant effort to nail this. Recap on specs

10900k on Asus Maximus XII hero Nzxt z73 360mm AiO 3600mhz 32gb cl16 ram (4x8gb) xmp I on

Overclocking to only 5.0ghz that’s all I want

Stable on manual is 1.3 with load line calibration level 5. Passed everything including 2 hours of prime95 small fft AVX off temps max at 77C after 2 hours.

-Swapped to adaptive with these settings-

Adaptive, auto offset, + offset sign

Max turbo voltage 1.300

SVID enable and SVID behavior best case

Cache max ratio x47

IA AC/DC loadlines set to .01

Load like calibration level 5

Vccio 1.1 System agent voltage 1.2

I can pass cinebench, realbench, OCCT large data set with AVX2 but I get about 20 minutes in prime95 and blue screen. I attribute this to vdroop but I need some help from someone who knows adaptive voltage on Asus.

Do I raise max turbo voltage? Do I add an offset not auto? Do I raise LLC? I just have no idea and with my current settings my scores and temps are amazing. I want this OC to work. I game and edit via adobe premiere so a bit of 1080p encoding.

Im begging for help(please don’t just say “just use manual”) that’s not what I want.

Dude, if it isnt stable and you really cant get it to be stable, then lower the clocks to 4.9, you wont notice the difference in ANY application you use, nothing will change, it will still be the fastest gaming CPU on the market currently, dont frustrate yourself with a ''MaGiC'' 5ghz number for no reason, its literally way above spec at 4.9ghz all core

Avx is just slowing your processor down so that avx instructions don't kill it because those particular types of operations are quite difficult and generate a lot of heat. Just increase the avx setting another notch, and the CPU will run a hundred megahertz lower and you should pass.

adding say + 0.020 v offset will add +0.020 v to both non avx and avx voltage .
if your 1.30v is dropping down to say 1.21v with load line 5 and is failing prime 95 with avx but all other non avx tittles like games and asus real bench all pass you need to add some offset + . try adding + 0.016v offset . intel works in 0.016v stacks .

try that then keep your hw info 64 app sensors tab open and watch what you drop down to under games and avx loads write it down . do these new changes go back re test write down what its dropping down to ect .

you can add + offset 0.016v or 0.020v or keep it the same and adjust your load line 1 notch higher but dubble check hardware info 64 sensors tab vcore min/max/avg with new load line change could be over shooting so you would then use less total turbo voltage 1.28v example .

/u/Bass_Junkie_xl is offering some solid advice. Try changing your voltage offset from auto (aka +0mv) to the smallest positive value available in your BIOS. If you still fail your P95 stress test, you can continue to raise your offset incrementally. Keep an eye on your CPU's core temp, as long as it's below 85C you have zero to reason stress about it in the slightest.

Are you using an AVX offset? What values are you getting for CPU voltage at idle and under load? How does this compare to your stable, manual OC?

Honestly if it was stable in everything you listed and not prime 95...if just roll with it. Almost nothing you can do it a real workstation scenario will push it like prime anyway

So I’ve passed 2 hours of OCCT large data sets AVX2, passed 4 hours of ROG realbench 2.56, 30 minutes of cinebench r20 loops. I get about 20 minutes into prime95 and unless I crank up LLC or offset I can’t pass it and it produces a bit of heat that is right outside what my cooler can keep up with.

Hello OP.

I think you understand when adaptive voltage takes effect. I can further explain it a little bit.

From my understanding, adaptive voltage kicks in when you use a turbo frequency. So if you set all core sync = 50x, then your adaptive voltage will kick in at 50x. When your CPU kicks down to something lower than 50x or a non-turbo multiplier, the CPU will revert back to its V/F point curve.

If you add an offset voltage on top of your adaptive manual voltage, that offset voltage will add to your turbo frequency or when your all core = 50x kicks in AND it also adds to the CPU's default V/F point curve.

You can also read a bit more about the features of your Z490 motherboard in the links below. Note that the original thread is for Z390 motherboard features, however most of them still apply to Z490 since the features did not change much from 9th gen intel to 10th gen intel.

Hope this helps explain a few things. But in general I think if you are crashing in prime95, it just means that there is a heavier AVX demand enabled and you need higher voltage for the more demanding workload.

In your post it says you can pass prime95 w/o AVX for 2 hours, but then when you run prime95 with AVX2, you crash within 20 minutes. Just up your voltage for this more demanding workload.

edit: To summarize Adaptive voltage is good because you can set the turbo (50x) mode voltage to what you require, while the CPU's non turbo mode (power saving frequencies) voltage will use it's default V/F curve settings instead. And offset (+/-) will add or subtract to both the adaptive (turbo) voltage and default CPU (nonturbo) voltage.

edit#2: Take a look at the link above around post# 9. See the imgur link below on the VF tool released by Shamino. I think he works for asus and has access to tools before they are released on the asus support website.

This is all wonderful info thank you. It’s been frustrating to say the least. I’m annoyed that everything will pass at lower vcore minus prime95 no AVX. I don’t feel like the load voltage is that low and many retail level 10900k’s are handling it just fine. It really feels like a true loss on the silicon lottery tbh. In your opinion since you seem very knowledgeable on this; if I can pass everything like ROG realbench for 4 hours, OCCT large data set AVX2 for 2 hours and cinebench loops for 30 minutes and all my temps are great do I really need worry about prime95 small fft?? When will gaming or adobe premiere EVER EVER impose that sort of load on the cpu?

Drop cache to 45, set vcore and llc accordingly. I guarantee if you drop the cache to 45 you will be able to get it stable.

I assume because higher cache requires more vcore?

Bro, stop. It's impossible to get stable all-core 5.0 for AVX or any demanding workloads on any of intel chips. I've tested it myself many times with 8700k and 9900k - it's hard to get even 4.8 all-core, because of how much voltage it requires, and thus cooling becomes impossible even with custom loops.

Many people have accomplished this with AiO coolers, you don't need a custom loop setup. If the silicon lottery is against you then sure, this might be an unrealistic goal, but reaching a stable 5.0ghz (AVX) OC is far from impossible.

Need help overclocking i9 10900k Some videos online but not much to go on. I'm fairly new to everything and I'm leaning something new everyday. Just finished overclocking my Asus Rog strix 2070 super Gaming Advanced and feel extremely proud even though I just followed instructions. Hope someone can reach out and lend a hand with a proper and semi safe overclock.

Thanks in advance

Water cooling idle at 28c and 50c at strain. 350 watts more with PSU then was recommended for my build.

Just need to know the steps needed in bios to properly overclock this CPU. I know nothing about it and don't want to over do it or mess up.

Step one: sell 10900k, Step two: buy Ryzen, Step three: overclock Ryzen, Step four: experience happiness.

If the OP is a gamer the 10900k is still king. Besides Ryzen doesn't over much unless you're using exotic cooling (LN2 for example).

Don't get me wrong Ryzen is a better general purpose architecture, but still loses in games and single threaded tasks. There are reasons not to buy it.
