Just installed my shiny new 5800X 3D and dialled in the RAM settings to precisely the same as I had with my outgoing 5600. Ran some gaming benchmarks... and it's WORSE - Superposition was down nearly 20%, Heaven was down from 4500 to 4250, and Shadow of the Tomb Raider came out within margin of error, but with admittedly much better CPU frametimes (and it went from 41% GPU bound to 70%).
 
BIOS has just been updated to latest stable, and aside from the RAM overclock, I have not touched any voltages - the 5600 and 5800X 3D are being compared stock for stock.
 
What on earth have I done/not done wrong?! I can't tell you how gutted I am to have spent £240 to get a WORSE gaming performance than a boggo 5600 I can keep hold of for nothing!

That was stock; just did a -25/-30 and got roughly equivalent CB23, but 10 degrees cooler.
Left it core cycling on SSE for 90 mins while I went to town, with Youtube running alongside, and no errors reported.
 
I've made my mind up on AM5 - Prime Week plus my Amazon employee discount should save me a few quid.

Just installed my new Ryzen 3600 and noticed that it is stuck at 4 GHz at all times and the CPU temperature continually "cycles" up and down, oscillating between high-30's and high-40's at idle. The vcore isn't locked but bounces around between 0.7 and 1.3+ V.
 
My old 2600 used to drop to 1.5 GHz and stay there at idle, with the voltage regularly living below 1V, and that's how I want my 3600 to behave.
 
All I have done in the BIOS is enable "global c-state control", set the RAM frequency to 3600 MHz, and set a -0.05 V undervolt - that's it. I haven't tampered with any clock speeds or other voltages or PBO or XFR or anything like that. I've been looking for a "Cool and Quiet" option but it doesn't seem to have one, and I've tried both Windows and Ryzen's "balanced" power setting with a 5% minimum setting.
 
Does anybody know how to get the 3000-series to downclock through the BIOS and/or Windows? I'm not installing Ryzen Master - I don't trust it.
