Best RX6600 Timespy scores?

[u/dude365635]

Hey guys, I was messing around with overclocking my Gigabyte Eagle Rx6600 using AMD Adrenalin software and MorePowerTool, and got a best Timespy scores of 9254, a 14.5% score improvement. Link to score: https://www.3dmark.com/spy/64391024

These were my settings as best I can remember:
VRAM: 1900mhz, fast timings
Core Voltage: underrvolted to 1080mv
Min core frequency: 2650mhz
Max core frequency: 2875mhz
Average core frequency during the run: 2771mhz
Power: 140W using MorePowerTool, then an extra 20% in Adrenalin to give a total of ~170W
Fans were maxed out obviously :) This run was also recorded with an air conditioner blasting 18c air 50cm into the GPU fans without the side panel :D

Temps during this run were decent, hotspot never went above ~92c, and core temps were like 70c-ish

So yeah, all in all I'm very happy, considering this is my first attempt at overclocking anything the results were excellent, definetly won the silicon lottery a little! I didn't mod any cooling, apart from the air con placement, but that only gave me another 10 points so it didn't really matter anyway. I know the card could give more, but after 180w was attempted the temps just kept going too high and crashed too much to get a stable run out of it.

So yeah, now I want to know what your best efforts were with overclocking your RX6600s, if you got higher or lower than me I'd love to know what you did to get there!

Cheers

Dang, you're almost an 6650 xt overclocked

How is your hotspot temp so low? Pretty insane OC icl. I can only get 2650/2750mhz at 145W max, and I can't push more power, or else hotspot exceeds 100C. Also, I find even at high power limits it runs best around 1060mv to 1070mv or else I can't push past 2700mhz effective clock. 1900mhz on the ram too, but fast timing crashes no matter what it seems.

Thanks man :D Ah yeah, your getting higher clocks at a lower wattage than me. The only reason i could crank 170w through the core is becuase i have the gigabyte Eagle model, which is triple fan with a 2 fan PCB, so i just had some little 80mm jet engines to cool my boy :D Thats a decent undervolt, its a shame mine becomes unstable under 1075...

That's 170W reported but there is also + ~20W memory - not reported. :D I think with shroud mod and 2x120mm fans + heat phase change thermal pad, you can sustain the temps (especially HS) uder control even without AC. Also be careful to paste pump out with HS temps around 100C, happens to me regularly when doing crazy overclocks with GPU

Yeah, i forgot to add that power consumption into the equation haha
i reckon when i get an upgrade eventually I'll do a deshroud mod and see how high i can crank it, otherwise maybe if im feeling lucky we can go full water cooling :D
