No display signal on new built MSI Z370 TOMAHAWK

[drfrankjacob]

I try to assemble my new PC but their is no display signal. My hardware is:

- MSI Z370 TOMAHAWK
- Intel Core i5-9600K 3700 1151V2
- Gain8GB D6 RTX 2070
- Enermax MaxTytan
- XILENCE CPU-Kühler I402 Perf. C-Series
- Tt Versa H23 Window

I already did google a lot and tried a lot without success:

- tried only one RAM dim in all slot and all combination
- tried a different monitor and all different inputs
- tried the minimum setup on my desk without the case
- bought a speaker (InLine 59910 Mainboard Testset), but no error beeps (only w/o any RAM)
- bought a second motherboard (Z370 PC PRO, LGA 1151), did not work either, tried everything above, still does not work

The second mainboard has 4 debug leds indicators. Non indicates shows an error. Only if I remove all RAMs the speaker beeps and the RAM led indicates.

Any advice highly appreciated - I have no clue!

The board's BIOS might not support that CPU.

It doesn't, need an 8th gen cpu to bios update for 9th gen cpus. Should have gone a z390 if this was newly bought. Sorry.
