Vega 64 Coupled With Ryzen 1700 - Abnormal Performance

Hi!
So it's been like 3 months since I've purchased my new gaming rig and to be fairly honest, there hasn't passed a single day, I could have told my self... "my system is 100% fine..., hell, not even 50%"...

My specs are as follows:
Ryzen 1700 | 3.8GHz @ 1.35V | Stock Cooler | Driver: 18.3.4

MSI X370 SLI PLUS | Latest BIOS | Latest Chipset Drivers

Sapphire Radeon RX Vega 64 (Limited Edition)

Corsair Vengeance LED (3000 MHz - 2 x 8GB) | 3000 MHz @ 1.35V

Crucial MX300 SSD (Boot Drive)
Seagate 4TB (Game Drive)

Antec HCP Platinum 1000W

LG 29UM60 UltraWide FreeSync monitor | DP -> 2560 x 1080 @ 75Hz

NOTE: A purely fresh Windows 10 Genuine Install with all the latest updates and only the core drivers (Chipset, Radeon). Also tried a simple 1080p monitor.. same results...

My problems are as follows:

  1. GTA V and a few other titles wouldn't run above 40 FPS, yeah!!! 40.... on ULTRA at the above mentioned resolution.
  2. When I activate the ReLive Overlay (Ctrl + Shift + O), it first crashes the Radeon Settings, then I have to relaunch it and then the Overlay works (intermittently)

I went further before reporting here, and replaced my motherboard (temporarily) with an ASUS B350 Prime Plus to make sure it wasn't motherboard related and yes it showed the same behaviour on either boards. I'm so frustrated for the last 3 months or so by these crashes and 40 FPS, that I'm on the brink of selling off my PC. I'd be highly obliged if anyone would be kind enough to help me in solving my issue...

Please find attached all the screenshots that I think may be of use...

Thanks,

Abdullah

I've had the exact same problems with my games since windows 10 FCU. Also turn on pstate leds and make sure it uses the max pstate.

Re: Vega 64 Coupled With Ryzen 1700 - Abnormal Performance

On the reference vegas, you can turn on 8 leds so you can see what core pstate the gpu is using. When all the 8 leds are on you are using the max power of the gpu. Unfortunately Rx vega can't go over core pstate 3​ I am the first that probably has your problem and the pstate can't go over p3 (4 leds on) thus resulting in embarassing performance.

I can't open the link that you've provided. It says, "Unauthorized".

It must be authorized, they should do it soon. Anyway turn on the gpu pstate leds with the switch on the right side (there is a switch for its color, red and blue near to it, and on the other side a bios switch, don't touch it). Then watch if all the leds are on.

Hello!

First, do a clean install of the chipset drivers and the Radeon drivers if you haven't done that already.  Make sure the AMD frame rate limiter, radeon chill, and virtual super resolution are all disabled.

The pstate LEDs are on..

as far as the "CLEAN" install goes, I already mentioned brother that I just re-installed Windows 10 with all the latest updates and for the drivers part, I just installed latest CHipset and Radeon from AMD Support website.

Beyond the settings I already mentioned, it would also be worth while to remove your CPU and DRAM overclocks, check your frame rate, and then reapply them one at a time.

Check you Radeon Settings and slide the power allowance up a bit, to about 20% and then recheck performance. Also, make sure you are using two separate runs of power to the card and do not daisy-chain them.

I'm running a similar setup with a higher resolution screen and my fps are totally fine.
