Question Turin Builders thread

[igor_kavinski]

About $4000. I may have forgotten some parts there, but thats the minimum. CPU alone was almost $2000

Still everything is almost half the price of retail CPU.

 

[Markfw]

Is that safe?

If you get it in the correct orientation and make sure its correctly placed in the socket. I have done 3 EPYC this way. You can see from the pic above that its correctly placed.

Happy crunching with it!👍

 

[Markfw]

Actually, I forgot a few things, like the 4080. About $5000-$5500.

 

[igor_kavinski]

I hope you swap that out for a R9700 32GB to make it an all AMD build in future.

Or pair it up with the Intel ARC dual GPU 48GB for giggles.

Done that with my 9950X3D. It drives the ARC A770 16GB.

My Ryzen be like, so you spent all that money on me just to prop up Intel's lame GPU???? Man, I feel so under-appreciated!

 

[Markfw]

OK, the 9755 will not post. First step, take out the 4080 and try off the inboard video ?

 

[igor_kavinski]

Yes, I guess.

Try with minimum RAM sticks?

 

[Markfw]

Yes, I guess.

Try with minimum RAM sticks?

Before I do, I have to replace the ram with some 4800 from somewhere. I found this in the users manual (worse compatibility than the H13-ssl-n motherboard, )

 

[igor_kavinski]

Ah I hate this mobo revision crap!

 

[Markfw]

2 sticks of 4800 from my 9534 and no go..... This CPU is going back.

 

[Markfw]

OK< I had to change out the CPU and get a new one from a difference source, as the one above would not post. This one is a 1535-05 and was $2100 ! But its alive ! Only running at 4800 ran, but its working !

 

[igor_kavinski]

You can do a 7-zip benchmark test if you want. One of the few benchmarks (other than probably CPU-Z) that will use all the cores and return a quick result, instead of waiting ten minutes for Cinebench.

 

[Markfw]

Any reliable windows tool to report total wattage used by the computer ? Or even just the CPU ?

 

[igor_kavinski]

OCCT: https://www.ocbase.com/

Works in Linux too.

1. HWMonitor says 460-480 watts ! Its running all 128 cores pretty much at 100% and avx-512 which is the most stressful. Really impressed with the arctic cooler that keeps it at 65c with this load.
   

 

[Markfw]

OK, 9755 number 2 is fired up ! Working on Windows install. iT SEEs THE 4080, BUT i CAN'T GET IT TO USE IT FOR DISPLAY !

 

[igor_kavinski]

Probably need to set PCIe slot as the primary display in BIOS instead of the sad 2D onboard chip.

I guess I don't know why I did not have to do that with the other 9755. Also, having a USB issue. I does not work on some sockets, and on one it worked for a couple of keystrokes, then stopped. But I am running primegrid on it, and the CPU seems fine.

 

[igor_kavinski]

Also, having a USB issue.

Maybe the BIOS needs an update.

 

[Markfw]

Oh, and here is a wild one. I changed the video cable of the kvm from DVIE to dosplay port, and it works on the KVM, but now it has 2 displays and I can figure out how to make the screens copies, instead of the displayport is all black. but the remote control from this computer is working fine.

 

[Markfw]

Oh, and the screen above using primegrid running, has simulated SMT disabled, so it can to pinning with lasso. 16 jobs with 8 CPUs each is 128.

dowcnlocked speed to 2.3 due to vrm temps. I need bigger vrm heatsinks, can't find them.

Temps on the new one.

Not an expert but how about stacking extra heatsinks on top of existing ones with thermal paste in between?

Anyone else who knows better should jump in before Markfw takes my bad advice

well, I can say that the existing heatsinks are a joke for a 500 watt CPU. I need to somehow increase their size or effectiveness.

(copying this from Zen 6 speculation thread)

They rarely go over 370 watt or so, except when fully utilized on all cores with very heavy avx-512 code running, THEN they hit 480 watts or so @2.7 ghz.

the 1245-08 is ES, the 1535-05 is a QS, should be the same as production/retail. If I load 256 jobs of WCG , it uses 370 watts on kill-a-watt. With 128 cores load with no SMT and heavy avx-512 (primegrid) it uses 480.

Do you recall what the average core clocks were with WCG Mapping Cancer Markers? (Or if not, would be nice if you could look this up after the PG challenge.)
