remove CPU and clean with Isopropanol(you may use wooden Q-tips from drugstore)
check socket pins with magnifying glass.
i guess CPU, report to seller and ask for replacement.

That is one of the typical behaviors when either as Rollo said - you have a dirty contact pads on a CPU, or you haven't correctly installed the CPU.
One thing to remember - always turn off the power either by removing a power cord or by switching off the power supply - as you must restart BMC after any change (including memory swaps). BMCs are clever and sort of lazy - they will try to cache the state and if you don't restart them - you might find yourself debugging error that was just cached.
Hello RolloZ170, could I have the modified BIOS too? I just recently read this forum and have learned that Q2SR is a good cpu. So I just purchased one and received it today. I'm going to get MS33-AR0 motherboard too. I've asked the cpu seller for the bios. But he just replied that just wait for 7 min to POST. So that please help. Thanks!
Hi!
If someone takes 2x Q2SR + ms73 for Deepseek R1, then here are the optimal bios settings:
Disable half of the cores on each socket (ffff0000ffff0000)
SNC=disabled
Numa=enabled
Virtual numa=disabled
The remaining settings for maximum performance, turn off the energy saver + turn on the frequency lock.
Launched via ik_llama.cpp:
numactl --interleave=all ./ik_llama.cpp/build/bin/llama-cli -m ~/DeepSeek-R1-Q4_K_M/DeepSeek-R1-Q4_K_M-00001-of-00009.gguf -ctk f16 -ctv f16 --numa numactl --numa distribute --threads 64 --ctx-size 8192 --seed 3407 -if
7,6-7,9 t/s

better disable every even or odd core thought.
write up the provided available bitmap and clear every second '1' bit(enables that core.)

I set f0f0f0f0f0f0f0f0, it turned out to be +0.5t/s, but I did not understand how to implement the second part of your message...("write up the provided available bitmap and clear every second '1' bit(enables that core.)")
no. the available bitmap shows you with '1' the cores. if there is a '0' its no core.
e.g. if you have a 48 core processor, there are deactivated cores in the bitmap you can not disable again.
set bitmap to 0 and reboot, set 0 again and reboot. now you have all cores enabled, what "avail. bitmap" do you see ?

i meant AAAAAAAAAAAAAAAA or 5555555555555555
the second is inportant in the case you have less than 64 cores of course or Sapphire Rapids.
big thanks to @RolloZ170 for his constant help in all matters, from choosing hardware to BIOS and windows tweaks. Huge respect for helping people and always being ready to help
Q2SR 2S + MS73-HB1 + 5090
5555555555555555 bitmap (32/64 per socket)
all works just fine
these waterblocks (Bykski CPU-SR4677-X) are surprisingly good for their 260 yuan price tag. They are full metal and very well machined, i actually expected them to be kinda meh, but in reality they're +- the same as iceman and ofc much better than alphacool etc.

Also if someone wondering how does it perform in gaming:
with 4800 16x16 congifuration and 32c HT1 (64 threads) per socket
SHOTR on market - 195 fps min
Starfield, New Atlantis - stable 160+ (very good, tuned x3d/RPL performance level)
Cyberpunk 2.01, city center - 140 avg, 130min
+- xmp 7950x gaming performance level (excl. starfield, in starfield perf is surprisingly good)
WoW cata classic, Orgrimmar center in rush hour - 140-160 FPS
all this on dual socket, on single socket it will 100% be better
also numa disable leads to lower FPS
turning off HT does not improve framerate
frametimes are very good, no stutters, no major drops, so you actually can play on this with some kind of comfort,
and that for me is surprising, especially considering that clock speed is just 4GHZ and no memory tuning.
Seems like large L2 and L3 doing its job.
i think for universal budget home workstation build something like ms03-ce0 with single Q2SR will be just stellar choice

i decided to get one of these F4Y1M Dell precision 5860 motherboards.
you can use a 750W Power Supply from Alienware R13/R14/R15, Prec. T3660, XPS 8950/60.
( Dell FT44X(orig.), 343WC, M92DC )
only the 1000W and up PSU has a ATX-SYS 12Pin.
the Dell 5pin to 4pin FAN Adapter comes from Amazon, SysFAN and RearFANs are 4pin, just cut of the empty 5th pin.and the latch.
i use a Nvidia GT630 and Micron 3400 512GB NVMe ssd PCIe 4.0
SPR-SP early stepping E0 Q08S/Q03J does not work, even the microcode is included in the stock BIOS.
This suggests that the Intel ME configuration doesn't like ES or XCC config.
BIOS modding is only possible with SPI programmer( test clamp )
the BIOS chip is a Macronix MX77L25650F with RPMC ( monotonic counter ) function which can be another hurdle.
update 27.04.25
- Xeon W?-34xx do not work. maybe blocked by ME or BIOS, the lack of Port80 Debug port maked it hard to debug.
update 02.05.2025
- read (and write) in circuit of the BIOS chip is not possible, you get corrupted data.
i have desoldered both chip (hot Air, shield with self adhesive copper foil) and will apply SMT sockets.
the first 16mb BIOS chip MX25L12872F contains the Intel ME, the second MX77L25650F is the BIOS region.
add both to one file and i can open the BIOS in UEFITool.
update 07.05.2025
machine don't start with modified BIOS, runs again with original dump.
microcode area is part of the protected reagions, so no chance for ES. i give up here.

I have a strange problem with a PC built on a AsRock W790 WS motherboard and CPU a QYFS.
In BIOS, in the Advanced section - CPU Configuration - Package C State - C2 state (also tried C0/C1 state); in Advanced - ACPI Configuration - Suspend to RAM - Enabled. Drivers for all devices in the device manager are installed, all are up-to-dated.
Problem: if the computer go to sleep mode (via the start menu) or if it goes into sleep mode due to a system timeout, when I go to reboot the system, it freezes on post codes slow change and does not can start normally. It can only be power off by holding the power button for 5 seconds and power on again.

* S3 (Sleep) mode is supported only when 1 / 2 / 4 DIMMs memory modules are installed.
2nd DIMMs are not refreshed,loose data.
May be my english is bad. I try with four modules in A2/B2/C2/D2 slots.
Problem another: PC not can normal reboot if was sleep mode in work cycle before.
same:
* S3 (Sleep) mode is supported only when 1 / 2 / 4 DIMMs memory modules are installed.
expect S3 is not supported with your hardware combination. the UEFI(BIOS) must support resume from S3 for all your devices,
if one fails S3 is gone.
edit: is tries to S3 but it doesn't work right
I have card for HDMI capture and to try make video with problem. May be video with describing problem is be some understanding.
My PC go in S3 waiting (all coolers is stoped) and return from it.
In paper manual with motherboard info "* S3 (Sleep) mode is supported only when 1 / 2 / 4 DIMMs memory modules are installed." is absent. In pdf manual it is present.
Very interesting. This may be due to the 4 Amps current limit on the 5VSB line, which is specified in the description of the "Suspend to RAM" option in BIOS. Mass of PC PSU have 2,5-3 Amps for 5VSB
