Question Anyway to improve my Ryzen 5 2600 OC?

Nov 6, 2019

CPU: Ryzen 5 2600

CPU Cooler: Coolmaster Hyper 212 RGB Black Edition

Mobo: AsRock B450m PRO4 w/ 3.60 BIOS

RAM: Team Series T-Force Vulcan Z DDR4 3200

For reference my OC is set in the BIOS itself not Ryzen Master and an odd quirk of my Mobo is there is no direct access to an LLC so you can only set the speed of the processor itself and it's voltage, that it.

The CPU is OC'd to 4.0 at 1.35v, I tried as low as 1.30, and 1.32 before going up to 1.35. I haven't tried 1.34 so there may be a little room to go down just a bit on the power needed itself for a stable OC. My RAM has had it's timings manually changed to 16, 18, 19, 36 @3200, it can "run" at 1.35v but it doesn't like it very much. It will pass stability tests via Ryzen DRAM calculators built in stress test, but if I access the BIOS the PC will tend to go through a few fail cycles before booting. However at 1.4v, the RAM is much happier and rarely tends to be pissy with me about booting from the BIOS, so it's set to 1.4.

Stress test wise I ran the CPU through multiple cinebench tests without fail, as well as a 10, 20, and 30 minute stress test on Prime95 using Small fft tests. Temp wise the CPU only got up to 70.1c at it's hottest but generally favored being around 68-69c.

I have attempted 4.1 at 1.35v but it just crashes the moment I attempt any test, so it doesn't appear I won the silicon in that regard. I have not attempted to push my RAM above stock yet due to its finicky nature.

Is 1.35 the limit of the "safe" voltage roof for this series of processor or should I try my luck at say a 4.1 OC with 1.38 maybe even up to 1.4 if it's stable?
