Discussion Raptor Lake Build Thread

Hey!

Can someone help me with undervolting my 13900k
i did undervolt using Intel XTU ,but temps are stil high. Current vCore offset is -0.07V , power limit 220W Pcores - 57 56 53 Ecores 44 44 44 44 43

also, is it oke to run 13900k on 220w with -0.07vcore offset and with clock speed i mention ?

Temps are over 85C in cinebench, in corona render a bit lower...

MB: Asrock taichi z790
CPU: 13900k
RAM: 128GB DDR5 5200 ( atm running @4800mhz)
PSU: Darkpro 4 1500w
GPU: 3090
M2: 2x2tb samsung 980pro
Cooling: Arctic Freezer II 420

Tomshardware has an article on this and your temps are expected. These are hot bois to try to cool. If you want to run it cooler at that power level, you're going to need a custom loop as that 420 is already top tier for AIO's. My NH-D15 struggles with my 13900K even at 200 watt cap. Getting into the 175 watt range it runs much cooler but then it slows down my video encoding considerably.

hey! thanks for ur answer! im still playing, now im at 210W 75-77C ...its very strange chip, i tried vith -0.150V and nothing cpu doesnt give a.. 1.40V . i think its something with my MB since i cannot undervolt from bios, some kind of bug.. im w8ing for bios update

After 2 days a better result with AlphaCool Aurora Pro with 2x140 mm Noiseblocker eLoop B14-PS Black Edition. 96 Celsius, 251W, 5.4 GHz P cores, 4.2 GHz E cores. And you can hear you thoughts and small talk conversations.... again.

huh 96C did u undervolt? out of box i got like 400w power and 107c hahahahahaha

An NH-D15 shouldn't be struggling with a 13900K at 200w?! What kind of case are you using and do you have proper ventilation?

I have a Noctua NH-U12A which is smaller than the NH-D15 and the highest package power temp I've seen is 84c at 220w power limit. I also undervolt mine however, so you may want to look into doing that.

I have the Thermalright version which is just as effective but cheaper. I think I paid $13 for mine.

@NGruia Why not just update the BIOS and drop the new CPU into the existing system?

 

[NGruia]

It's a holiday gift!
I will choose a day when he is not at home and install the processor in his computer.
Surprise.

Makes a lot more sense than building a new system just for an upgrade. Quick 15 minute job.

I'm thinking, don't tell him anything. Let him use the system for a while until he realizes that something's changed. Maybe put a hidden cam somewhere to record his face expressions when he rubs his eyes and thinks he's going crazy coz task manager says it's a 13th gen CPU

This is strange. According to Noctua, they rate the D15 for up to 183W so according to Noctua 200W would be pushing it.

The Noctua U12A that you and I are both using Noctua rates to 169W. My case is moving air pretty well and the U12A works well for me at 175W, after that temps start to got high 80's on the highest temp cores. This is when I'm seeing a package power of 180W in HWinfo, or about 172W core power.

I see that you have your rig set to 220W but is that actually what you are seeing in HWinfo when you are stressing your system and the highest temp you're observing is 84C?

 

[shorty1111]

one more question...how to get arctic freezer II 420 pump to work 2000rpm ? now its only 1500rpm. i set everyting to max speed...

 

[DooKey]

CPU at stock, HSF tower setting in BIOS gives me a 28922 CB23 score.

I've managed to raise my CB23 score to 30415 by increasing my DDR5 freq to 7000 and tightening up the timings as well as increasing my ring freq to 4.7ghz. Not too shabby.

That rating isn't in watts, it's the result of an equation that measures several different factors to get a more accurate measurement of heat dissipation. If you scroll down a bit more on that page it shows you how they arrive at that number.

I see that you have your rig set to 220W but is that actually what you are seeing in HWinfo when you are stressing your system and the highest temp you're observing is 84C?

Yes. The screenshot I posted several pages ago shows a maximum package power temp of 78c @ 220w, but I had the heat turned off in the room where the computer is kept so it was very cold.

With the heat turned on it would have been 84c:

Jeez, you really have that rig dialed in. I'm going to try a contact frame to see what that does for my temps.
When you lowered the voltage by 0.1 did you subtract it at all 11 points in the BIOS or is there somewhere you can take it globally? I couldn't find a global setting.

 

[lopri]

Anyone running 13700K with DDR4? Want to know if my Cinebench R23 (multi) score is normal. I am getting 25~26K points, and I see DDR5 systems getting 30K. Not that I need more performance - I plan to use the system with HT and E cores disabled - but it's just a curiosity thing.

I still think your main issue is your case. I googled it and it didn't inspire much confidence to be honest. It looked way to claustrophobic for my tastes, and unless you bought extra fans, it only comes with one rear exhaust fan in stock configuration.

One of the biggest reasons why I have such good temp is because of my case. The Fractal Torrent is an air moving monster. No stagnant or hot air anywhere inside my case.

You don't want to lower it globally, just for the CPU Vcore. Just find the CPU Vcore, put it in offset mode and use the minus sign and then set it to 0.100v. You should be able to do it since you're already limiting your CPU to 175w.

I don't know how much you're losing by going with DDR4, but I do know you'd get more performance with DDR5. Also, be careful about disabling the E cores. I disabled the E cores and ran the Aida64 memory and cache and the scores were substantially lower which surprised me. I think the E cores are more integrated now with the P cores than they were in Alder Lake so there might be more consequences for turning them off.

I hear you regarding my ancient case. I do have two quality Noctua fans moving quite a bit of air and no discrete GPU so it's pretty wide open in there. Tomorrow I'll open it up and put a really powerful fan blowing into it and see if things change as far as temps.

 

[Markfw]

I have to say, is it really worth a couple percent faster over Zen 4 for all of this heat and cooling problems ? Not trying to troll, but pages of this, and it sounds serious.

Nah. My system is running great day-to-day. Absolutely unbelievably stable. Actually the most robust machine I've ever built. It's fun to try and optimize things when I have time to fool around with it. I could leave it at 175 watts and it's still be 30+% faster than the 12700K that is replaced but I enjoy tweaking and testing.

I ran Phenom II and FX back in the days. I think these are fine.
