First, you can read my usual reply to such at https://www.cnet.com/forums/discussions/pc-keeps-rebooting/
AS to your goal, the motherboard maker has to tell you which BIOS and settings to use as well as tell you that RAM on that board and CPU will reach those numbers.
So I recently put together a new computer and am having a very odd issue with the mobo/RAM.
So the build in question has the following parts.
Mobo: AsRock 450m Pro4
CPU: Ryzen 5 2600
GPU: XFX RX 580 8 gb Black Edition
RAM: Team Series T-Force Vulcan 3200 x2 8 Gb (16 Gigs)
Power Supply: EVGA 80+ Gold 500w
SSD: NVME SSD Sabarent Rocket 512 gb (only drive, No HDD or other SSD's)
The Bios/drivers on the board are up to the current 3.60 update via the installation disc and self updating via the Drivers client. However, the internet was running through a external wifi dongle and was sometimes a bit... off so i am wondering if the drivers could be a bit screwed up. Regardless, everything works fine, games run smooth, i can run Grim Dawn, WoW, etc without any issues that i have noticed. The RAM however is only running at 2400. The ram is designed to work at 3200 but the highest speed i can get is 2666.
The RAM itself is in the A1 and B1 slots on the mobo, i used CPU-Z to check and it is running in dual channel and when it defaults to 2400 or 2666 via tinkering, i can see it in CPU Z. However if i turn on the XMP profile and set the RAM to 2933 (i forget that exact number) 3000, or 3200, it staggers, reboots several times, and then defaults back to 2400.
I have toyed with the Voltage a bit and curiously, the XMP profile attempts to set it to 1.35 but the Mobo flags that as inappropriate and highlights it in red. i've set it down to 1.20 for now and that runs 2666 just fine, but i bought 3200, the board can handle 3200 (I checked, both parts are compatible) so i'll be damned if i don''t stop trying until i get the 3200!
Can someone please help me figure out what I could do?
