No visual output with dual RAM modules.
I recently assembled a gaming PC. The motherboard is an ‘Asrock B450m hdv rev. 4.0’. It has two RAM slots. Inserting both sticks doesn’t produce a display. Swapping them works if one slot is empty, but inserting a stick in slot 2 always results in no display. I bought another RAM kit (two 8GB sticks) but it didn’t help. When I checked the BIOS with one stick in and increased the voltage to 1.34V, the PC restarted itself off again. Removing the stick restored normal operation. I purchased a new PSU just in case, but it didn’t make a difference. Is this just a faulty motherboard? I ordered a replacement and it’s on its way. I haven’t removed the old one yet. Thank you for your assistance.
Could you share the specific RAM kit models and the CPU and BIOS version you’re running? I’m assuming the problem might be related to the BIOS, so an update could help resolve it.
I was previously running Corsair LPX with 2x8GB at 2400MHz, now switching to g.skill Ripjaws with 2x8GB at 3600MHz. The processor is a Ryzen 3 3100 and I'm using the newest BIOS version ‘10.12’, though it remains in beta.
Consider lowering the specs to an earlier full release version to test improvement. Attach photos of the memory stick labels to show the die changes. These revisions play a key role in RAM compatibility, and you can compare them using model numbers from Corsair and G.Skill listings.
The devices in your images have distinct specifications: one uses DDR4 2400 MT/s with CL 16-16-16-39 (1.2v) and another runs DDR4 3600 MT/s CL 18-22-22-42 (1.35v). To make them work together, the quicker module must support 2400 MT/s or you'll have to overclock the slower one to 3600 MT/s. The slower module should either match the 1.35v or the faster one must operate at 1.2v. It seems the stick is sensitive to higher voltage levels. Remember, you mentioned having a memory kit with two identical modules?
I changed the bios to an earlier release labeled ‘10.10’ and returned to the original RAM, the Corsair model, which should only require 1.2v power. Both sticks were inserted, but no screen was visible. I removed the stick from slot 1, then swapped it into slot 2 and put it back in slot 1, and the display functioned normally.
