Ryzen 7 3800xt

[Sam F]

I have a Ryzen 7 3800xt and noticed under load my CPU wont boost to its advertised 4.7GHz. I have tried cinebench single and all core test along with CPU-Z. My temps are around 72c max load on all cores but 60 with one core.

What speeds do you see in cinebench single threaded?

 

That speed isn't present on all workloads, and some workloads need more power, so they won't run at as high of a clock speed. This is pretty normal for these chips.

And it only has to hit that for 1millisecond to be honest, and you might not even catch it in the 1000ms updates most programs update at.

so then whats the point of the boost?

usualy two threads hit 4.5GHZ and all core is 4.275

Boost is ALWAYS opportunistic, would you rather 1ms of 4.6Ghz?
1ms was made up by me as an example...of why you might not catch it in spec/stat programs.

I believe with PBO I'm hitting around 4.2ghz - 4.4ghz - but one core on the CCX1 is going a bit higher.

 

What are your scores looking like, mine are slightly below what I'd consider avg for the CPU but I'm also running on an older x370 motherboard and with DDR3200 @ XMP profile not overclocked beyond that (I believe my board has a theoretical max of 3400mhz because of it's layout - although the BIOS does have the option to try to push it beyond to 3600mhz).

I got a score of 5112

As mentioned before, boost is usually only single core and is more often than not the MAX you'll see. 4.5GHz boost is still pretty good for a 3800xt.

Any OC ideas?

To be honest with Ryzen and especially Ryzen 3000, it's not worth overclocking. Letting PBO and the algorithms built in to the chip / BIOS do their thing is the best option. 

However there are tools like Clock Tuner by 1usmus that aims to get the best overclock out of your chip. I've read reports that it tends to lean on the more unstable overclock in favour of higher clock speed though so that's something to look out for.

I'm currently getting a score of 4734 MC and 496 Single core. 

Performance increase came from using the ASUS Dual Intelligent Processor app from the AI suite - moved all the phase controls (CPU & DRAM) to ultra fast and increased capacity on the power draw settings. 

My room is currently a bit below ambient but stemps on CCD1 and the Tctl go from high 40s - 50.0 idle to 79/80. I don't have my fans ramp up - they stay fixed at 1100rpm.

I'd love to get it up higher, but I think it's my ram holding me back.

Also pulling about 9400 in 3D Mark Timespy, if relevant. 

I'm mostly playing WZ and I went from about 90 - 100 FPS to 100 - 130, which is nice bump while playing 1440p @144hz. I haven't put the CPU through it's paces in Adobe CC yet but I'm expecting a 20+ % boost over all.
