1950x for a good (UBT) home

Having problems installing that new stick of memory? Found some great software or having issues with something? Or maybe want to chat about your PlayStation, X-Box, Nintendo, Sega, even your old Spectrum 48k....! Or maybe something you want to sell or acquire (computing related of course!). Let us know here...

I was mistaken :oops:

Tctl is 94 degrees
Tdie is 68 degrees

So if I'm reading the specification right, that's the limits and it's throttling.

Think I need another heatsink fan (at least)

Yep, sounds very hot indeed and pushing its max temp (68 degrees according to the spec sheet). I wonder if that’s why you are generating invalid units??

Sounds like you have a Linux box but, if you do have windows on it, try grabbing the Ryzen Master utility. It will give you a much better idea of what’s going on.

On the positive side, we reached #6 top producer in QuChem a couple of days back, and recently took #8 on the FB board.

Once this box is humming away, we will be in a very nice spot indeed.

I did wonder when the heatsink only covered about half of the heatspreader.
I don't think the invalids are related, they've all been tried by someone else and failed there as well.

Checking I get this:

Code: Select all

mark@:~$ sensors | grep "Tdie"
Tdie:         +67.9°C  (high = +70.0°C)
Tdie:         +68.1°C  (high = +70.0°C)
mark@:~$ cat /proc/cpuinfo | grep "cpu MHz"
cpu MHz		: 3187.559
cpu MHz		: 3187.813
cpu MHz		: 3187.988
cpu MHz		: 3186.614
cpu MHz		: 3188.799
cpu MHz		: 3188.590
cpu MHz		: 3188.835
cpu MHz		: 3189.073
cpu MHz		: 3184.809
cpu MHz		: 3184.932
cpu MHz		: 3184.990
cpu MHz		: 3185.087
cpu MHz		: 3185.134
cpu MHz		: 3185.270
cpu MHz		: 3185.347
cpu MHz		: 3184.911
cpu MHz		: 3189.982
cpu MHz		: 3190.178
cpu MHz		: 3190.203
cpu MHz		: 3188.323
cpu MHz		: 3190.438
cpu MHz		: 3190.226
cpu MHz		: 3190.470
cpu MHz		: 3190.741
cpu MHz		: 3186.472
cpu MHz		: 3186.635
cpu MHz		: 3186.689
cpu MHz		: 3186.782
cpu MHz		: 3186.812
cpu MHz		: 3186.963
cpu MHz		: 3187.035
cpu MHz		: 3186.597
So what's the all core turbo supposed to be? Is it actually throttling? - [edit]3.7GHz apparently so it IS throttling :(

Either way, time to wait for in progress tasks to finish, shut it down and add more fans :)
Maybe use some proper heatsink paste as well rather than what came with the HSF?

Most of the QuChem output is down to you :o

New heatsink paste and a second fan:

Code: Select all

mark@:~$ sensors | grep "Tdie"
Tdie:         +65.4°C  (high = +70.0°C)
Tdie:         +65.8°C  (high = +70.0°C)
mark@:~$ cat /proc/cpuinfo | grep "cpu MHz"
cpu MHz		: 3406.946
cpu MHz		: 3407.187
cpu MHz		: 3407.393
cpu MHz		: 3408.054
cpu MHz		: 3408.300
cpu MHz		: 3408.622
cpu MHz		: 3408.763
cpu MHz		: 3409.107
cpu MHz		: 3409.788
cpu MHz		: 3410.049
cpu MHz		: 3410.199
cpu MHz		: 3410.449
cpu MHz		: 3410.428

cpu MHz		: 3411.467
cpu MHz		: 3411.638
cpu MHz		: 3411.908
cpu MHz		: 3412.047
cpu MHz		: 3412.284
cpu MHz		: 3412.900
cpu MHz		: 3413.215
cpu MHz		: 3413.379
cpu MHz		: 3413.627
cpu MHz		: 3413.809
cpu MHz		: 3414.093
cpu MHz		: 3414.215
cpu MHz		: 3414.507
Just within spec but not throttling, 68 degrees and 3.4GHz :)

I think I'm going to look at AIOs or at least, a bigger HSF (although this one is recommended by AMD on their website as being able to handle threadrippers, maybe I'll try playing with fan profiles?)

Yeah, that ran around 3.7GHz most of the time under good water cooling. It did fluctuate a bit here and there.

Looks like there are only a few percentage points in it.

I'm not sure if being right next to the GPU is affecting it either.

Some options to try anyway, there may be some BIOS values to change as well.

Decided to go for one of these - https://www.coolermaster.com/catalog/co ... 0-rgb-tr4/

Due in on Friday so hopefully I'll be up to 5GHz by Monday :lol:

Nice one. Hope you have a big case :)
