hello forum,
my system is getting older now and i would like to boosts its ability please?
im not new to overclocking as i got my AMD™ FX 8350 up to 4.7ghz.
the problem is i cannot understand how or where or the why of improving the AMD™ Ryzen 7 3800XT.
can you explain nice and easy please? as im just a user and not an expert.
the platform is the older MSI™ X370 gaming carbon pro.

i do intend to upgrade to AMD™ 9800X3D.

best regards,
Mr Perforations

Nice and easy gaming explanation:
Considering you have a 7900XTX, in many games, you would gain approx. +35-70% FPS if you moved from the 3800XT to a 7800X3D depending on the game and resolution (1080p/1440p would gain more than 4K).
That said, your motherboard is compatible with the 5800X3D which would give you approx. +25-50% FPS.

As far as improving performance of the 3800XT, it's basically impossible. I had a 3900X. Nothing you change will help much and manual overclocking will cause a performance regression in most scenarios, especially lightly threaded applications/gaming.

To maximize efficiency set the Infinity Fabric to half of your RAM (DOCP/XMP) speed. You can gain ~200MHz (if that is worth it to you) by enabling PBO Advanced + OC 200MHz

(And I recommend to stop doing these different colors at all...

It's just terrible for people using the dark UI.)

But back tot opic: Does your board offer PBO as an option? If yes, try this. If no (latest bios version?), then you could only overclock with a fixed factor, right? But I wouldn't recommend an allcore OC, if PBO was available, so check this first.

For an allcore setting there is Hydra (formerly known as CTR, to be found at Patreon or Igor's Lab) which helps to find the highest possible stable frequency per CCD. Sometimes this tool works and sometimes it doesn't. Or do this manually with setting the freq in the BIOS and then do your own stability tests.

I have a 3800XT and I have never seen one that would hit its advertised boost clocks of 4.7 sustained boost on even 1 core, during any sort of meaningful workload. I have mine at 4.6ghz all core and 3866 CL 14-13-13-32. The PBO algorithm for the Zen 2 CPUs is and was terrible. Everyone is going to tell you not to all core OC with this CPU but, to put it simply overclock the core and ram as far as you can, and get the ram timings as tight as possible. I noticed a 20% improvement in 1% lows and 15-18% in averages for free. But do what best suits you. I have a 7900XTX as well, and play @ 1080 and 1440.
