help with undervolting 5800x3d

@Jacks.
The -30 CO offset is getting applied properly, otherwise you'd be seeing 1.25-1.30V max CPU Core Voltage in R23. There seems to be a general problem with thermals in your system, though. This may be due to high room ambient. Could you verify your room temperature? It seems to me it may be well over 30C.

This is what I got after 30 minutes of R23 in a 25C room, with -30 CO on all cores:

i have no idea but it feels like 28 i got nothing to measure it with
 
exchange ? you mean rma ? oh god this gonna be hell don't wanna go near that they will not rma this is not the us mate i'm from africa-egypt here you bought it it's done unless it's not working at all
have you took a look to my post above ? i have edited it

my condolences

I assumed that if it was a recent purchase, you could make use of return policy.

Your CPU isn't really behaving out of the ordinary so far which is good news, most of my suspicions still rest with your cooler. If ambient is to blame then your room would have to be like 35C......is it that hot?

Again, if you can get your hands on another decent cooler, it should help shed light on this problem.

it's a recent purchase only 4 days ago

no it's not that hot feels like 28c really and have you seen the last post with the pic in it ? i did report on going back to 4006 and test also the ram i did run cyberpunk 2077 benchmark didn't exceed 75c no idea if this is helpful btw just to be sure what is your definition of a good cpu mount ? i'm sure mine is it's locked tight but just in case
 
I have to run it at 143w PPT for it to get up to 80, these things run pretty nice.

So...is ambient actually 28C or not? What it "feels" like doesn't make it any clearer.

Motherboard temp is not quite ambient but in relative terms, I'm at about 30C mobo in the morning with an ambient of about 22C ish.

Yes, I did see your pic. No, Cyberpunk benchmark is not helpful, 5800X3D is usually at most in the 50-60s during gaming.

Like I said, 90C running full stock, no curve, and pulling 110-130W is normal for any 5800X3D. You're hitting 90C at 95W, with what should be a top of the line cooler.

Is the Galahad new?

i don't know honestly
Is the Galahad new?
yes bought it new a year ago
EDIT:
ok let's talk about coolers what is the best of the best cooler for my cpu ?
keep in mind the hot zone i live in

I would say PPT-limits, -30 CO and probably lowering SOC, IOD etc is mandatory on 5800X3D unless you have really good cooling.
 
cooler contact is good i checked that twice ,i was able yesterday to get it under control with modifying the values in the limits tab didn't exceed 87c in cb r23 scoring 14200 no matter what values i enter in the curve tab it didn't do anything and yes it shows -30 when i open the program again , i will check the mount for the third time i just ordered Kryonaut Thermal Paste for absolutely no reason except being very sure of everything
i'm still waiting for this guide :D

the Galahad is not good :cry: you're kidding right ?!! it was doing a good job on 5600x and 5700x i can't afford to buy another cooler
btw you have Dark Hero board i heard that curve optimizer is available in the bios on it is that true?
Dont forget that AIO's can just die - 2022 was the year of AIO failures.

New a year ago could mean its failed now, I'll see if Lian Li was specifcally hit with any of these issues
 
Have you guys with the 5800X3D played around with CPU LLC?

I can get up to +/-400 extra points in R23 using LLC 3 On my MSi mobo but this can vary from board to board and different brands.
You guys should go through a few settings and see if there is any improvement in R23 scores running different LLC levels.
 
Weird website name, but they've got some complaints about the galahad here

It's like the voltage and clock speed are tied together, a positive offset on the voltage boosts too

Positive offset also boosts temps like no tomorrow.
LLC helps.
1.2Vcore at all-core load is or should be more than sufficient for 4GHz to 4.45GHz all-core speed.

I cant set SMT to on at~4.6GHz all-core without it reaching temps into high 80s-low 90s C within seconds. Gotta pursue a monoblock remount and add fans to radiator(one 120mm atm).

Ok let's say that my cooler failed or it can't handel this much heat
what are my options? Air and liquid?

There's no chance your 360mm AIO "can't handle" the heat if it was working properly. You really don't need anything fancy for 5800X3D, especially if you can use PBO2 Tuner. You're not making it past 4450MHz all-core anyway, without BCLK overclock. I'm using the equivalent of a NH-U14S, and with -30 and 90W limits I'm at 76C in R23.

Cinebench is a good reference for temps, but in games the 5800X3D should always run significantly cooler than Cinebench. And if you bought the 5800X3D to run Cinebench you've got your priorities seriously wrong lol.

Even assuming your place has a 35C ambient (I'm sorry for your loss), an air cooler will still be fine. This isn't like a 5950X where a crappy cooler will seriously hold your clocks or performance back. A lot of people will hit 90C at stock, but if you haven't noticed, pretty much everyone's scores in R23 fall between 14000-15000pts. 5800X3D is designed to deliver the gaming performance without high end cooling or expensive RAM.

Just get literally any cooler that is NH-U12S level performance or better that won't break the bank, and use it to verify if your Galahad is working properly. Then you'll have a cooler that can keep you going while you RMA the AIO, if it's indeed the problem.

I'm using Cooler Master's MA612 a single tower air cooler for my 5800x3d in a small SFF case. I live in a very hot place sometime reaching 40c feel, it was reaching 85c underload but putting CO to -30 all cores kept it under 80c. I can't imagine 360mm AIO reaching that high, so I think there's something wrong with the cooler.

i was thinking going to Noctua NH-D15 chromax.black it's too big and pricey it will fit with the rest of my hardware what do you think ?
a friend mentioned Thermalright FC140 CPU Air Cooler but it's not being sold here it's 61 us dollars plus 95 dollars to ship to egypt which is ridiculous
i really need suggestions
and yes i bought it for gaming but right now i'm disappointed and frustrated
 
Noctua NH U12A

Not sure why a D15 wouldn't fit a normal Hero in a normal ATX case. FC140 is just as big as D15 if size is a concern for you.

You can get FC140 off Aliexpress, no?

There's a couple of cheap but good coolers, Vetroo V5 off the top of my head. NH-U12S redux is also fine if you can find one. I don't think you're reading what I said. I only suggested you get a cooler to troubleshoot what's wrong with your Galahad, and RMA it if necessary. I did not say that you need to break the bank for a 5800X3D.
 
i don't see the difference between it and NH-D15 chromax just fan size i guess right?

The D15 is much larger...

I'm running an i7 12700K with this U12A cooler.

The 7-heatpipe U12A has almost similar performance as it's 6-heapipe D15 larger brother.

Aliexpress is a no here, also NH-U12S redux it's here but they wouldn't sell it with out a complete build it's a common practice here bad thing i know most of the hardware here you can't but separately you have to buy a full pc to get it you have no idea what i did to get my build done anyway ,troubleshoot and RMA the Galahad i don't think they will honor the RMA policy or whatever they call it that's why i skipped the troubleshooting part it's a great loss for me i just hope to find a way to buy u12a or d15
 
u12a or d15

Whatever cooler you buy, be sure they fit your motherboard(vrm heatsinks) , memory height and case...

Fair enough. D15 should be fine with Ballistix height, your case has plenty of clearance, your x16 slot is moved down a slot so it shouldn't interfere with GPU

If you're going for an all black aesthetic, the U12A Chromax is usually obscenely overpriced for what it is. But it's similar to a D15 in a smaller package size.

You can also look for Scythe Fuma 2, Deepcool AK620, etc.
