No thanks. Used to be running on a precision cluster. The machines were ok but the fact we couldn't tweak more performance out of them made me a bit annoyed.

So far through benchmarks, we found about a 2-3% in certain phase of processing especially where RAM usage is very high. In some others not so much as the software is GPU dependent in some phases. Of course the largest improvement was in improving the cooling of the system by tweaking the airflow though the casing and AIO and also improving the contact between the heat block and CPU. The CPU stayed at higher clock speeds for longer resulting in almost 5% everywhere.

The software somehow responds better to higher clock speeds than more parallel cores. Before this when we were using precisions, we had a 8 core 3.8ghz Xeon running on ddr3 and a 22 core 2.x GHz running on ddr4. We found the 8 core still churning out data faster than the 22 core. That's why my quest to have stable and higher clock speeds as opposed to more cores.

Do you know how many cores can your code scales?

but amd with EXPO with giv u even more headache.. n its unending

Commercial software. Closed source. But the preference of clock speeds over core count was verified by the developer. All cores can be used but I believe the algorithm is highly iterative in nature

So far the stability is something that is understood and can be solved. Actually dell also has precision with AMD. Just not sold here. A friendly company who does the same software processing in the states tested and Vs intel and prefers AMD so we follow their recommendation.

Also I don't know why your experience with amd is so bad. Mine after a bios rest has never taken more than 10 minutes for a ram relearn and my interns made mistakes in assembling resulting in a slower machine. Slow but stable. Even when they forgot to connect the main connector into the heat pump block on the CPU, the system just immediately shutdown. But nothing as chronic as what you described.

Stock settings crash? Just RMA. Clearly faulty CPU. Stock settings does not fix CPU already got degraded from mobo's out of spec boosting.

is a widespread issue now

more will come, bcoz 14th gen still very new

Lucky me didn't let the mobo decide. Already running at stock with undervolt from the beginning.

how u know this earlier??

usually buy high end , people tend to boost clock, overclock.

12900K to 13900K got significant boost with performance using same process node. Big clock speed boost too. 13900K is technically an "overclocked" CPU at stock. Pushing it further will degrade it faster.

There are a lot of Asus, & MSI mobo users (these 2 are the main culprits that automatically enable 4095W power limit setting when detect Ksku)

If faulty just RMA, when get back the replacement just set in Bios to follow baseline power limit and all is good again.

See mobo.. mid range n above less trouble.. the 1 giv me unending headache use x670p.. while the b650 tomahawk less issue ..but memory training still occur.. expo certified ram worse compatibility than xmp ram

U building more pc? I got AMD target to meet.. haha

Not this quarter. Depends on what contracts we get. probably will need more hardware during Q4 if we win tender

Hi Guys,

Just an update to show where my "bottleneck" and main cause for concern is



Here you can see the loading of the CPU. The casing is a NZXT H9 Flow with the 360 radiator at the top and fans blowing out. The rear fan blows out and the bottom 3 and side 3 blow in.



Despite setting all the fans to run at 100% including the pump and radiator fans, you can see the large difference between coolant and CPU temp. I am worried I didn't install the pump properly or does anyone here have any tips to improve the cooler performance?

95 is.. abnormal?

check the thermal paste

This is Ryzen AM5, 95C is absolutely 'normal' according to AMD

Did not see that I should reply to you; Ryzen AM5, 95C is absolutely 'normal' according to AMD

BUT there is a way to bring it down by undervolting & underclocking the CPU and here is how

The 95 is not the issue. My worry is the massive difference between the coolant temp and CPU temp. You can use GPU temp kinda like ambient temp in the casing
