Dual Channel Ram slots do not boot

Dual Channel Ram slots do not boot
« on: June 19, 2020, 07:08:41 am »
I have a Z370P D3 motherboard and 4 identical sticks of Corsair LPX 3000mhz 8GB. All 4 sticks work and boot my pc in slots 1 and 3, but any combination of slots 2 and 4 will cause the motherboard to not boot. If installed in either slot, there is a continuous series of long beeps that doesnt stop.

Any recommendations on what I can try to get this working with all 4 sticks? Thanks

Specs:
Intel i5-9400F
Gigabyte Z370P D3
GTX 1650 Super
4x8GB Corsair LPX 3000mhz
2tb Seagate Barracuda 120 SSD
600W 80+ PSU

Greetings,

The 9500F supports 2133, 2400 and 2600 natively.  It requires BIOS F12 or later.

First thing to check:

Are the RAM modules on the QVL for your board?

Since 3000Mhz requires a slight OC, you may have to set memory timing and voltage manually if an XMP profile is not available.  Support however sill depends on the RAM and/or BIOS rev.

Check to see if you might have a bent pin in the CPU socket. The memory runs through the CPU.

After messing around in the bios with the timings for about 2 hours, I checked the cpu slot pins and it turns out one was bent all the way back... no idea how that happened.

Bent it back and aligned the pin, all ram slots are working perfectly and the sticks have no issues booting.

Thanks all for the suggestions!
