Memory Mystery

[reflux]

Hi guys,

Just bought a 32GB 3600mhz Patriot kit to upgrade from my current 16GB 3000mhz Corsair kit. Part number for the new Patriot kit is PVS432G360C8K. It should run 3600mhz at CAS 18.

Unfortunately I can't get it to run at the rated speed/latencies at all, regardless of the settings I'm using.

Here's what I've tried:

• Updating to latest BIOS (dated July this year)
• Setting SOC and VDDC voltage manually to 1.1v
• Setting DRAM voltage to 1.4v
• Setting 'gear down mode' to enabled
• Setting XMP profile 1
• Setting XMP profile 2
• Manually setting DRAM speed, FCLK and basic latencies

Nothing seems to work. The machine will boot with default RAM settings - 2666mhz and dreadful latencies, but nothing else I've tried will boot.

System specs as follows:

• Ryzen 3700X
• MSI X370 Gaming Pro Carbon flashed to latest BIOS

I've checked and the RAM isn't on the QVL for this board, so it may be completely a no-go, but is there anything else I can try to get this new kit to run at 3600mhz / CAS 18?

Cheers

Yeah, I've got it to boot with some pretty slow timings at 2933.



Gonna see if I can keep increasing the speed with some lax timings, and then reduce them slowly.
