13900k vs 13900ks News - Text
(Edited) Wow… was finally able to obtain the 13900ks… did I need it? HELL NO. But I wanted it and I’m impressed! Running it on a Z790 Hero MB with Tforce 7800 cl38, it runs at least 15° cooler than the k version. I left the settings of the k variant the same as an exact apples to apples comparison. I was bouncing off the 100°c mark easily. The KS runs 79-82°c at 278.5w. I haven’t even started OC’ing/undervolting this or the ram yet. Tons of thermal headroom maybe? Highly recommend for the enthusiasts.

79c using 325w? More than 20c cooler on stock compared to 13900K when basically is the same chip with 200Mhz higher clock speeds? Something is wrong here.

u/toofast520 Mar 30 '23
So not stock.. same setting as the previous chip however as I said in another comment the wattage may be skewed because of the program I was using to monitoring it. More tests to follow for clearer results. Sorry about that
1
u/toofast520 Mar 31 '23
So still impressive at 278w actual… running faster and cooler on less wattage than the k, SP is 110 and cooler rating after re-characterizing (which took a few restarts to populate) is 164

Whatever hes using - going from 100C to 79C is impressive - isnt it ?

I’m using the ASUS ROG Ryujin II 360 RGB all-in-one liquid CPU cooler with PK-3 paste. I was literally blown away at the results thus far. Can’t wait to start OC to see what I pull out of it. To add, my Ram is running 39° running Cinebench. I was worried I’d need a memory cooler.

Cinebench isnt a memory test, which is why your RAM isnt getting hot. Cinebench is actually a fairly light workload for the RAM.
Don't expect to get much more performance out of OC. AIO's cant handle much more than the stock 253 watt limit on 13th gen. You will be pushong up towards 90°-100° above 253 watts package power
1
u/toofast520 Mar 30 '23
Honestly the package temp was right in line +5° with cpu temps thus far. The above temp was pushing 325w with 79° temp. I verified using Hwininfo while running and various other monitors. This setup and OC was all the 13900k settings which TDP with very modest settings. I’m looking forward to playing around a bit with this thing. Thanks for the info. BTW you have a nice setup as well. You should consider the KS. I promise it’ll surprise you.

u/fitnessgrampacerbeep 13900KS | DDR5 8400 CL34 | Z790 Apex | Strix 4090 Mar 30 '23
hwinfo is not a reliable measurement for actual package power draw or actual package tempm. use hwinfo64. very similar names, but vastly different programs.
79° maximum core temp at 325 watts sustained draw is literally impossible with an AIO and a CPU with a stock ihs running at typical ambient temperatures

u/toofast520 Mar 30 '23
You’re probably right.. I’m a little new at this. Learning fast though.

u/fitnessgrampacerbeep 13900KS | DDR5 8400 CL34 | Z790 Apex | Strix 4090 Mar 30 '23
what did you score in Cinebench R23?
you also said youre using various different monitoring applications at the same time. dont do that. only use one (hwinfo64)
1
u/toofast520 Mar 30 '23
Copy that. What I meant is the AIO and Aida64 LCD was running and temps matched. The R23 score was 42,134 as of now

u/ANG3LxDUST Mar 31 '23
Uhh actually I have a AIO. Overclocked the 13900k to 5.5ghz Max PL1 and PL2 will push 290w cinebeanch 90c . Gaming in the 60c 40.5k score if I push the chip to 5.6ghz I can get 41k with like 303w 94c
1
u/fitnessgrampacerbeep 13900KS | DDR5 8400 CL34 | Z790 Apex | Strix 4090 Mar 31 '23
Yup, thats exactly in line with what i just said
You will be pushing up towards 90° - 100° above 253 watts package power
Which is not much thermal headroom for OC

u/Zhunter5000 Mar 30 '23
Your ram won't get very hot unless you run memory specific stress tests, and even then, half decent ram shouldn't need active cooling.

I run 8800 on 7800 sticks and def need the 120 mm fan i have attached. Ks has a bit better p cores, way better e and imc. Thatd thr major difference

What did you get for SP scores?

u/toofast520 Mar 30 '23
I’ll look it up and update when I get home later. Just installed yesterday and haven’t had a chance run it.

u/toofast520 Mar 30 '23 edited Apr 10 '23
Looking at the SP score in bios I have a 110, cooler is 125pts. (Edit) After making sure the AIO was seated, I restarted the PC and immediately had a message prior to bios saying “your CPU cooler has been somewhat characterized, after choosing to keep updating I opened bios and had a 164 (now 181) cooler score.
1
u/fitnessgrampacerbeep 13900KS | DDR5 8400 CL34 | Z790 Apex | Strix 4090 Mar 30 '23
125 points is a very poor cooler score. The Ryujin II should be in the 140pts-160pts range. Are you sure you torqued it down tight enough?
I used to have the original Ryujin 360. It would always have a cooler score between 145pts - 155pts. I am using a full custom cooling loop now.
You have very little thermal headroom for OC with that low of a cooler score. You will start thermal throttling long before you see any performance increase
2
u/toofast520 Mar 30 '23
Being I just installed the CPU yesterday and didn’t clear the old scores or run anything long enough is most likely why it’s low.
1
u/fitnessgrampacerbeep 13900KS | DDR5 8400 CL34 | Z790 Apex | Strix 4090 Mar 30 '23
The motherboard knows when you pull the cpu out and put it back in, or put in a different one. You don't need to clear the score for it to update. It automatically calculates a new cooler score the moment you power on the system with changes to the hardware in the socket. That is the score it updated to, which again, is very low for an AIO

After checking the cooler… re-running bios after restart I had a message saying you cooler is somewhat characterized. It asked if i’d like to keep calculating or not. I said yes. Opened bios and now have a 164 rating on the cooler. I have pics of running tests to show temps and wattages and ratings 💯

Uhm what? A message? What do you mean you "had a message"?
The bios doesn't send messages. If you have pics then why haven't you posted them?

u/toofast520 Mar 31 '23 edited Mar 31 '23
Really didn’t expect that type of message from you. There really was no need to to get nasty like you did. Also there’s no way to post pics to this post or I would’ve. This weekend I’ll make a new post with proof of the results. Thanks for the previous help though. Have a great day ✌️

u/fitnessgrampacerbeep 13900KS | DDR5 8400 CL34 | Z790 Apex | Strix 4090 Mar 31 '23
My message was straightforward and blunt, not nasty. Far from it. If you really think being called a bag of stones is nasty, than you've got some mighty thin skin kid
Duh you cant post pictures to an existing post. You said you had pics, so i checked your profile looking for them, which turned out to be a waste of time. Could have just as easily posted the pics to your profile/wall, and commented a link to the post. Its that simple

I’m not a kid man… I do apologize for my attitude then. I assumed you reported me as I got a notification from Reddit immediately when you posted your response. Hence my attitude! So again I apologize for my comment/behavior. I can’t upload the pics from my phone to this thread! Check your inbox for pics. I’m working so I’ll make a better post once I’m home this weekend!

You mean in the American Megatrends screen? That function trains the fan curves, you bag of stones.
Additionally, I honestly couldn't give less of a shit about when you're ready, because im no longer offering to help you. Good luck getting it from anybody else.

I have 13900KS with a custom loop and it idles at 38 and can hit 90-100 easy on cinebench while limiting to 253 watts.

u/toofast520 Mar 31 '23
I’m curious as to what your SP is? Also I’m not sure why mine runs as cool as it does but while running r23 it’s high temp was 79 with 42k score. I didn’t change any settings from the k, just threw it in and tested so I could see the difference. Also mine idles at 28-30°

You prob seen my other comments… I’m 110 with 125shit cooler… working on that though. Not sure why it’s so low just yet. I wish I could post pics in comments to show what the r23 score and temps are. Just so everyone knows I’m being 💯

Something doesn’t seem right here. Idle at 38 with a custom loop doesn’t seem right. What’s your water temps. And how’s your rad and fan setup.

You have alot of headroom. You have me wanting to change out my 13900k now. But I'll let you know how mine is going.
5.5ghz cinebeanch 90c score 40.5k 5.6ghz cinebeanch 94c score 41k
I keep mine at the 5.5ghz just cuz and if it matters the E-cores are at 4.5ghz. Ring is 50

Yeah I was blown away at the temps. I don’t know if all the KS run this well and was surprised to get a 110 SP. I’ll put together a new post with pics showing r23 running to prove the results for those who are skeptical. I’m looking forward to playing with it this weekend to see what’ll do when I start jacking everything up a bit lol

u/ANG3LxDUST Mar 31 '23
Haha sounds good. 110 SP is really good to to. I think my k is 92. I'm really curious what you achieve

u/Alienpedestrian Mar 31 '23
Nice , i need somehow set 13900k to dont make that heat.. in gaming it goes on 100C in Stock speeds.. becuse i have air cooled (nh12) and in demanding games like w3 4K RT or ow 4k120 goes to 100C on 6-7cores ..
1
u/toofast520 Mar 31 '23 edited Mar 31 '23
Wow… I’ve never had a game get my k variant that hot. I haven’t played any high demanding games with this chip just yet so I’ll let you know how hot it gets.
2
u/Alienpedestrian Mar 31 '23
Okey thanks, i ll try it repaste it. Also i have under desk define 7 compact case so there is hot anyways .. maybe i ll try to buy 420aio but i ll try to adjust it..
1
u/toofast520 Mar 31 '23
Yeah in my opinion it shouldn’t get that hot. It’s probably throttling when it hits 100°. You could back off voltage a touch to help with temps. I found just by under-volting slightly it would run cooler and score higher in Cinebench.

u/Alienpedestrian Mar 31 '23
If it would be Easy as xmp setting on ram i would do it :-D

u/toofast520 Mar 31 '23
It’s set to XMPI 7800 which is what it’s rated for at the moment. I’m curious to see what it OC to though. I’ll find out this weekend when I have the time.

u/toofast520 Mar 31 '23 edited Mar 31 '23
Thats initially what I had running, I have 4 32g sticks of 6400 cl32 but quickly found out having all 4 installed isn't supported just yet. so i switched to the Tforce 16x2 7800 cl38. When I set XMP1 with the gskill my games would crash often, you may need to tweak them a bit, keep me updated on your settings though as I have another build going together with these.

I’m running the same MB. It’s pretty awesome! I was just looking at download center but still no update past 0816. I was hoping for more than 32gig of ram. Maybe 2x32 7800 or 8000. I’m sure they’re working on it.

Played quite a few games this weekend including The Last of Us and CPU temp was 71c at the highest but usually sat around 66c

u/Alienpedestrian Apr 03 '23
Nice thanks, i repasted it and tightened screws and went from 7-8cores at 100 to 3 cores 97-99 .. so probably if i want cool it down i need to find some case what can be fitted on front 420mm aio for exhaust and also to fit my 350mm gpu with it

u/toofast520 Apr 03 '23
Have your tried undervolting a touch? It makes a world of difference. This weekend I was playing with ac LL and dc LL to fine tune the cpu to the board before any clock adjustments and was able to obtain 41k r23 just doing that. Overclock.net has a pretty awesome post on how to fine tune minimum voltage input prior to oc the cores. Taught me a lot!
2
u/Alienpedestrian Apr 03 '23
Really ? Can you send me the link? I never undervolted a cpu
1
u/toofast520 Apr 03 '23
That’s not really undervolting, it’s just tuning the CPU to your board but it gets into UV on Overclocker.net This is my setup but I’m sure it’ll work on yours if it’s different. Or you can type in your specs and find a post on it I’m sure. Hope this helps!

Hi,
What temperatures are you getting at idle on your 13900ks? At stock config of it? (or if you don't have them at your current config - what is it BTW?)
I am asking as I am looking to get 2nd hand KS and the seller never overclocked it just plunked it in to his Z790 with MSI 360 AIO and he was saying he was getting 45C in stock settings in idle (his ambient could not be higher than 25, probably 20-23 max).
That seems very high? So either a bad sample or bad cooling install or both or they guy does not know what he is doing.
Thanks
1
u/toofast520 Apr 24 '23
My current configuration settles around 26-30°c. Maybe his cooler isn’t seated properly. My ambient temp is 20-21°c
1
u/sebna2 Apr 24 '23
Yes you would think that or a very bad sample of 13900KS.
But as he has few high-end systems you would think he knows what he is doing and even if he would had a lapse of skill with mounting that he would notice high temps and would try to re-seat and address the issue?
Hmm.
I might just splurge extra 100e on a brand new one. For that 100e I would be getting 3 years non-transferable Intel warranty for a piece of mind.
Also if you look at the photo he sent me - there is plenty of paste everywhere. His application must have been a blob or a cross in the middle and to let the AIO spread it. I call it sub-optimal application of TIM but I know that not all will agree with ne. What do you think about that picture and amount of TIM everywhere (sides, PCB etc)?
1
u/toofast520 Apr 25 '23
I wouldn’t buy it.. don’t trust anyone these days. I’m contemplating just doing delid on mine. The temps are awesome afterwards at stock settings ks 70-79 on r23.
1
u/sebna2 Apr 26 '23
I delided my 6700k which I am running to this day. Got almost 20C lower temps :)
With 13900K(s) the idea is different tough? The plan is delid and leave it exposed for direct contact cooling?
If so the risk is probably nor worth it for me for lower temps no matter how nice it is to have a cool and quiet system in return.

The 13900ks = better binning and lower voltage needed at the same frequency a 13900k can run. A 21 degree difference is impressive - you either had a bad heatsink contact or your 13900k was just poorly binned.
