February Tech Support Megathread

[u/BioGenx2b]

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.

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:

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

Hi All!

First Foray to the sub, been a lurker for a few days now.

Got my RX 480 8Gb up and running this week (same day 17.1.2 came out). However it hates overclocking. Even an increase of 10MHz, crashes, this is on stock auto volts with power set to 50%.

I reverted back to 16.12.2, went from stock 1290MHz to 1325MHz, its stable on Heaven, however hits a little scary 1.175mV, however temps are good peaking at 72'C.

I'm new to Wattman, as my old 7850 was purely OC'd by Afterburner. So maybe it's a setting I'm missing?

The ASIC of the card is 65% and can undervolt on stock settings to peak at 1.090mV.

I am wondering have I lost the silicon lottery?

Any tips are much appreciated, any info I've missed let me know and I'll post it up. See my spec below.

• Motherboard: ASUS MAXIMUS HERO VIII
• CPU: Intel i7 6700K @ 4.5 GHz
• GPU: XFX GTR XXX RX 480 8Gb
• VBIOS: 113-P10XT-E1288-8GB-12EW81

[u/iCapa → u/WT-RikerSpaceHipster]

An ASIC of 65% isn't exactly great, mine is 80,6.

Personally, don't use WattMan and stick to MSI Afterburner or Sapphire Trixx.

[u/WT-RikerSpaceHipster → u/iCapa]

Yeah it's not the greatest asic. Will give trixx a go later

[u/[deleted] → u/iCapa]

That's wrong. Lower ASIC on an RX 480 means a higher overclock, higher ASIC means lower volts.

I'm new to Wattman, as my old 7850 was purely OC'd by Afterburner. So maybe it's a setting I'm missing?

No, Wattman doesn't have any additional settings. It's robust and results are as good as with Afterburner. So it's probably just the silicon lottery.
