Having a strange issue with only 2080ti cards on my Zenith Extreme. I've updated to the provided beta 1501 bios from elmor via overclockers.net forum for resolution of the nvlink '0E Vga Bios Load' error (which is now resolved), however this NVRAM Test error occured even before the beta bios update with 1402.
Issue only occurs if a 2080ti is inserted into slot PCIE16X_1. I've tried (2) seperate 2080ti's on this port with same issue, both in single gpu and multipgpu/nvlink mode. Issue does not occur if a 980ti or TitanXp/1080ti is inserted into the same PCIE16X_1 slot and system will run fine without errors. Again, issue only occurs if a 2080ti card is inserted in the PCIE16x_1 slot. It does not matter if it is single gpu or multgpu with another 2080 in another slot, issues will present. IF 2080ti card(s) are moved to any other slot or slot configuration that does not use PCIE16x_1 port, system functions normally without issue and no errors. This, however, limits one card to 8x if used in multigpu nvlink.
symptoms: mobo is continuously throwing a 92 TEST NVRAM code, with delayed posts, system halts after post, issues after windows loads (freezing, screen goes black, system reboots, windows runs at like 1fps when moving mouse.
I have tried everything, clearing CMOS, default settings, even stripping components down to the bare minimum, only KB/M plugged into USB, nothing else except ram and NVMe drive plugged into mobo. Same outcome.
Any suggestions or assistance at all would be greatly appreciated. This issue was present in 1402, and still in the 1501 beta bios released today.
