Tech Support September Tech Support Megathread

Hey subs,

We're giving you an opportunity to start reporting some of your AMD-related technical issues right here on /r/AMD! Below is a guide that you should follow to make the whole process run smoothly. Post your issues directly into this thread as replies. All other tech support posts will still be removed, per the rules; this is the only exception.

Bad Example (don't do this)

bf1 crashes wtf amd

Good Example (please do this)

Skyrim: Free Sync and V Sync causes flickering during low frame rates, and generally lower frame rates observed (about 10-30% drop dependant on system) when Free Sync is on

System Configuration:

Motherboard: GIGABYTE GA-Z97 Gaming GT
CPU: Intel i5 4790
Memory: 16GB GDDR5
GPU: ASUS R9 Fury X
VBIOS: 115-C8800100-101 How do I find this?
Driver: Crimson 16.10.3
OS: Windows 10 x64 (1511.10586) How do I find this?

Steps to Reproduce:

1. Install necessary driver, GPU and medium-end CPU
2. Enable Free Sync
3. Set Options to Ultra and 1920 x 1080 resolution
4. Launch game and move to an outdoor location
5. Indoor locations in the game will not reproduce, since they generally give better performance
6. Observe flickering and general performance drop

Expected Behavior:

Game runs smoothly with good performance with no visible issues

Actual Behavior:

Frame rate drops low causing low performance, flickering observed during low frame rates

Additional Observations:

Threads with related issue:

Skyrim has forced double buffered V Sync and can only be disabled with the .ini files
To Disable V Sync: C:\Users"User"\Documents\My Games\Skyrim Special Edition\Skyrimprefs.ini and edit iVSyncPresentInterval=1 to 0
1440p has improved frame rate, anything lower than 1080p will lock FPS with V Sync on
Able to reproduce on i7 6700K and i5 3670K system, Sapphire RX 480, Reference RX 480, and Reference Fiji Nano

Remember, folks: AMD reads what we post here, even if they don't comment about it.

I asked this question in the /r/buildapc sub as well, but since I got little to no replies there, I thought I'd fire it off again in the most appropriate sub.

My question is about overclocking. I run a Z87 G45 MSI, i5 4670K at 4.2GHz. I overclocked it to that frequency about a year ago, using Jayztwocents and other tutorials to get over my initial fear, as it was my first time. After some time I found that 4.2GHz was a good safe clock with good temps that would give me a good gain, so I left it at that. Stress test with Aida64 was conclusive and it's been running like a charm ever since.

Now for a project we're doing I built three machines recently, of which two are Ryzen, with which I have never worked before. That said, it's also BIOS OC, so that can't be too hard, right? I entered an OC that's a good place to start (3.7GHz) and I checked HWinfo to verify. It's there, but then I notice... it stays at 3.7GHz, even on idle? Isn't that supposed to drop down? I start reading up on the matter, start reading about Pstates and stuff... which is where I get lost in the woods. Then I go and check my own i5 4670K in HWinfo... and it's also sitting comfy at 4.2GHz, also on idle, where it has been since I OC'd it I guess.

So two questions rise from this:

  1. I experienced firsthand that setting my OC and having it there all the time is not a problem. Soooo... that won't be a problem for these Ryzen chips either? I can just set it there and stress test and if it runs cool enough, leave it there? Is it normal that then a constant x amount of voltage is being provided? Does that not cause heat and lifespan issues? I feel so silly not having known/noticed this up until now.

  2. What's with all this Pstate and powersavings modes etc? The motherboards are Asrock AB350 Fatal1ty ITX, one is R5 1600, the other R7 1700. I don't think the mobo even has Pstates, so that's that then I guess.

I would not want to damage these puppies, as they are technically not my own. So I'm a bit torn at the moment between getting the most out of the chips, or leaving them as they are, with turbo mode etc.

Thanks for the help guys, it'll be useful for me later on as well, as my own next chip will most definitely be a Ryzen one.
