Question ASUS PRIME Z270-AR - Low hashrate with GPUs - HiveOS ?

[jkrm]

Hello. My friend bought an ASUS PRIME Z270-AR and he is using 4 gpus for mining. 3 GPUS are getting very low hashrates, only the 5700xt is getting the full potential (on any slot). We already tried changing slots, changing risers, and nothing.. we know that the risers and gpus are working fine.. he was mining with another mobo with no problem after he bought this one. (mobo stopped working so he bought this new one)

Things we tried already:

• Updating the bios
• DMI Max Link Speed to GEN2
• PEG Port Configuration to both GEN2
• PCIE Speed to GEN2
• HD Audio Controller to Disabled
• Serial Port Configuration OFF
• Above 4G Decoding to Enabled

Heres a pic of what looks like on HiveOS:

hash rate is affected by ram modules used, your have samsung which is good, u might want to flash modded vbios with patched ram timings there

But it was working fine with another mobo.. And we've seen people mining with 7 gpus on this mobo, very strange..
