Dear Level1 forum members
I have built a workstation using the
ASUS Pro WS WRX80E - SAGE SE WIFI II Motherboard along with
AMD Ryzen Threadripper pro 5965WX 24-Cores
But from the day one the CPU core voltage was hovering around 0.25v and peak speed of under one hundred MHZ TO 900 MHZ vary ( picture in attachment ) causing issue with processing power resulting in blank , white , black screens unable to show the data and charts . while as you know 1.3v+ with minimum of 3.1 Ghz @ idle is a norm.
i suspect the processor is a faulty but in orher to stablish that , the following steps were carried out :
1- updated the BIOS to the latest 1302 .
2- initially installed 8x (16 Gb ) ECC memory
( 64GB Kit 4x16GB DDR4-3200 PC4-25600 ECC UDIMM 2Rx8 Unbuffered Server Memory by NEMIX RAM)
were replaced by :
( Kingston Server Premier 16GB 3200MT/s DDR4 ECC CL22 DIMM 1Rx8 Server Memory Micron F - KSM32ES8/16MF )
just to see if the issue continue to persist.
4- we made sure according the user manual power connectors @ page 9 of user manual , the PCIE-8PIN-PWR connector ( C ) as well as PCIE-PWR-1 & PCIE-PWR-2 ( E & F ) are all connected for additional direc supply of power for multiple GPU usage.
( A 2000W PSU used in this workstation build to support heavy loading & multiple graphic cards . ) no economy mode switch was enabled @ the back of PSU .
5- windows was updated and blue/black/white screen troubleshooting was carried out .
6 - However , the Ryzen Master upon launching send a pop-up message from the get go as follow :
( Overclocking feature is not supported by the processor. Hence only current view is visible and you will not be able to switch to other profiles. ) while the ryzen 5965 wx is overclockable to 4.5 GHZ from 3.8 MHZ clock speed.
Is this a locked CPU they sent me ? ! !
7- all graphics card were removed & an HDMI plugable adaptor was connected straight to the MB using USB 3 in the back of motherboard to see if it is a graphics cards compatibility issue causing it . Also was made sure no traces of graphics drivers left on the system and BIOS was reset @ this stage as well as single approved kingston memory stick was used which made no difference in CPU peak speed or performance or DRAMA !
it is important to mention the following :
-
In Ryzen master non of profile 1 , profile 2 , creator mode , gaming mode are enabled on the left colomn .
-
In idle mode 23 out of 24 cores are sleeping , randomly a 2nd core wakes up for couple seconds then back to sleep
-
when we first built this workstation, the screw on M.2 heat sink snapped for absolutely no reason hence we had to install the SSD on second available slot .
-
while @ idle the CPU peak speed fluctuates as low as 73 MHZ to randomly low hundreds and back , However , under cinebench 23 multicore benchmark it revs up to 4.3 GHZ and stays @ that speed for duration of bench mark . then immidiately the peak speed drops to random low hundreds as soon as the load is removed.
-
. Temperature during the cinebench is 68-71 . & 35’ when idle .
Enermax 360 mm .liquid cooling is used.
cinebench score of 41400 .
BIOS up-to-date.
windows 11 pro up-to-date .
with all my amature thinking i suspect the following two possibilities :
A - factory-set, conservative power limits on motherboard causing it
B - possible faulty CPU conclusion.
I was wondering if any change of setting in BIOS can help with the issue that we are unaware of or this particular Motherboard has a known specific setting requirement or any physical change of switches on motherboard ie ( BMC )!? !
PSU : 2000W EVGA PSU is used .
Your help & advise will be very much appreciated .
