just a quick heads up guys doing phone support for a friend built the system up with the b450m pro4 (on my recommendation) and he was stuck with no display........... after much ado he got display working by using the LOWER PCIE slot for graphics card (this is a long slot but only x4 wired) now the issue and how to resolve enter bios and change the pcie switch from GEN3 to auto reboot and you will now have display on the top pcie x16 slot the problem was a BAD written bios design/defaults .............  ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |
