I have fitted a H11DSU-iN into my 819U chassis now need to sort the 1U coolers. Only have experience using fan coolers. Is a passive cooler good enough for this? Supermicro fan snk-p0062p 1u h11 amd epyc 7000 sp3 cpu cooler | eBay - possible current option. I will be using high end TDP Rome...

Supermicro SYS-F618H6-FTPT+ look good. Does SM offer these trays that support EPYC 7002/7003 in that chassis? Thinking of long term upgrades

I am not looking to dedicated cores to VMs

NUMA nodes per socket is set to "Auto" Rebooted the VM again, seems to sometimes boot in a bad condition If it helps root@proxmoxhost3:~# numastat node0 node1 numa_hit 195958341659 214547960812 numa_miss 0...

You took too long to type that out :) But thanks for the answer. Rebooting the VM gives great results, for how long I don't know, even without NUMA enabled I will try both. I still don't understand why the host machine has poor performance though. The result in the first post was taken from...

Could this be an issue with NUMA not being enabled on each VM? Would not explain why the memory test still sucks on the Proxmox host itself though.

I have a system with Supermicro H12DSi-N6 with 2x EPYC 7642 once the system starts going above 30% CPU usage in the overall graph I noticed a steep decrease in memory performance and the system feels sluggish overall. How can I identify what might be the cause? sysbench --test=memory...

Most the ones I reached out to do that too but this one doesn't.

I'm from the UK, planning on getting some cheap colocation hosting in USA soon. Have a few questions hope you guys can help me out with as this will be my first rack. Network stack plan is to use the following 2x Mikrotik CCR2116-12G-4S+ 2x Mikrotik CRS326-24S+2Q+RM 1x CRS326-24G-2S+RM (IPMI)...

Ok thank you both will leave it unplugged. The PSU are not being detected either way in IPMI

What if I do not plug the PMBus cable in at all? Is there any major downsides

What do you need from me to check compatibility?

Removing the pmbus cable does fix this. I don't know how I can adjust the configuration you're talking about.

I have an issue with my mz32-ar0 (rev3) inside a Supermicro 826. Tested this with multiple servers now after noticing. If I pull the plug on one of my 2 PSU (so that it buzzes loudly) the system starts to perform very slowly. These are Supermicro PWS-920P-SQ 920W so there is plenty of extra...

Getting the following errors since I moved this to a new machine. EfiBlockIOReadBlocks: LBA out of range BlockIO-Command Failed What's the work around? Wont let me in BIOS

What is the equivalent to Supermicro Health Event Log for "Correctable ECC / other correctable memory error @DIMMB2 - Assertion" in a Gigabyte BMC. I presume it's Logs & Reports - System Log done loads of testing was expecting to get at least one error somewhere.

Probably closer to this. I have a ASRock X570D4U Ryzen 5950X running 4x M391A4G43AB1-CWE Samsung 32GB DDR4 PC4-25600 3200MHz (clocked down to 2666) 32768.00 MiB transferred (15221.04 MiB/sec) General statistics: total time: 2.1523s total number of events...

I don't have 8 3200 so I can't confirm that. Speed difference with 4/8 2400/2933 is not much. They show correct frequency.

What RAM would you guys put in the following system MZ32-AR0 EPYC 7643 I bought a few SKhynix 64GB 2Rx4 PC4-2933Y-R83-12 HMAA8GR7MJR4N-WM the performance isn't that much better than the Micron 32GB PC4-2400T-R RDIMM MTA36ASF4G72PZ-2G3 I had sysbench --test=memory --memory-block-size=4G...

@i386 @gb00s Do either of you know if TYAN s8036 would detect the PSU information? (Supermicro 826 chassis)
