I have currently overclocked my R5 5500 to 4.45GHz with PBO2 + Curve Optimizer.
– Settings for CO are per core, with all cores being -15 and my best being -13.
– Memory is running 1.4v 3066MHz 16-20-20-38 with the infinity fabric at 1533 stable. Lowkey shitty memory speeds, but I think I got unlucky with my Samsung C-die RAM.
– Also have my clock speeds set +200Mhz
– Follow these memory controller settings in this video as well, helps a lot. : https://www.youtube.com/watch?v=xOlVYPKu10s
– Cooling solution currently is a Wraith Prism (I know, not amazing) so leave recs for what I should get on a budget under $30ish.

OCCT: Memory tests were superb, CPU stability is good as well, however my cooler gets a little fussy during OCCT stress tests hitting 85-90 deg celcius.

Testing scores

Cinebench 2024 – Cooler never broke 70C
MC: 630
SC: 88

CPU-Z – cooler never broke 65C
SC: 603
MC: 4828
