[Solved] Terrible Performance X399 Taichi & Ryzen

I'm with Xaltar.

Everyone should spend the time to learn OC'ing in the BIOS.

OC Apps IMO are for those that do not want to and suffer the consequences for having done so.

Moba, that's a rant and it is NOT directed at you personally, 'k?

Just that OC sw, while run in/from the Windows environ, is a recipe for disaster.

No offense taken .

I finished my little experiment last night with Ryzen Master and I think it confirms common wisdom about overclocking from Windows.

First, I couldn't replicate the slow down nor find anything interesting in the registry. Second, I had 1 BSOD after applying settings which could have been a disaster considering how the UEFI is linked to Windows (I hate UEFI). So what useful information did I find?

Well, Game Mode does what it says it does, even on regular Ryzen i.e. it disables half the cores. However, it does nothing to improve latency across CCX modules (there's no cross die traffic unless you have a Threadripper processor...duh). I tested this with Sandra and Aida on multiple runs with the same results (inline with what was published online at launch last year i.e. latency is lowered with memory clock speed). Using 4 cores in legacy mode also introduced random stuttering in games - losing as much as 50% of my FPS for short periods while the CPU was pegged at 100% for no apparent reason. YMMV .

In conclusion, memory speed is the best way to lower latency on Ryzen up to a point of diminishing returns. Game Mode, while a nice plug and play solution in theory, adds absolutely nothing when using it on a standard Ryzen chip. And while performance improvements in Game Mode have been shown in certain situations from published Threadripper reviews, I still wouldn't rely on it with such an expensive build.

And the UEFI? Well, when I tried disabling 4 cores in the UEFI to replicate what Game Mode does, the UEFI froze completely, even after a few power cycle. Since I didn't find any worthwhile improvements from disabling cores for my needs, I won't investigate this any further...

Well, any solution to the OP's problem of terrible performance 0n X399 Taichi because I don't see a solution mentioned or outlined here?????..... my cpu mark results are craaaaaap like what has been mentioned in this thread so what's the fix????

And the OP not coming here or returning my txts pretty much seals the deal that I will not be spending hours on the phone helping others in the future.

I too on a new install had great performance, it was after updates/installs for no repeatable reason performance would drop again. My workaround was to use Macrium to restore when performance dropped and then redo the installs etc. until I was fully built. I had to do the restores several times but all seems good now. Man what a freeeeken hassle of a fix that may or may not work or needs repeated reinstalls to get working.....no fix really!!!!....people shouldn't have to go through that sort of a hassle!!.....Asrock needs to look at how they have tweaked the bios and fix the issue on their end.

What the hell are you carrying on about? You don't even know WHY he needed, no, REQUIRED, a fresh OS install.

Get real.
