According to The Stilt the lower asic score represents less leakage and therefore less heat and power use at the same voltage. While lower leakage also means needing higher voltage for the same switching speed or clock rate, you may be using less watts at the same voltage and will have fewer hot spots on your GPU. For air, a lower ASIC can be advantageous.

Experience says this isn't 100% accurate. Perhaps there's a happy medium. Your ASIC is very low. I'd love to get a Killawatt on your system and see the difference between your power use at a particular voltage and mine. You might have much more room for your power limit if you use less watts for the same voltage and therefore you might be able to run much higher voltages before you start bumping into diminishing returns. It would be interesting to test.

Well I messed with Wattman a little more. I set the PState 4-6 to 12701275. The voltages were dropped to 1110. I upped the memory to 1850. Left the power target a the max.

I ran Firestrike...no problems. Sailed right through it. Here is a comparison of the RX 470 v GTX 970(stock settings):


Actually beats the 970 in Graphics. thumb.gif

Like I said, as I learn more about Wattman I hope I'll find a happy medium in there. I mean, I've only had the card a few hours....and this is the first time I've seen Wattman.

Setting multiple p-states in WattMan to identical values is counter-productive. It works much better and is more stable f day to day usage if you build up a curve.

The reason for this is that the software interpolates from one step to the next. With a big jump, you could end up with an unstable frequency/voltage combination.

How can i untervolt the 470 / 480 in the bios ? Or set the offset ? I know somewheree in the i want to change the offset on the 470 / 480 in the bios

Use HxD in combination with a calculator and Atombiosreader.

added VDDC and VDDCI offset "inside" the rom with a HexEditor.(powerplay tabel / dpm state table )

But u know where excatly i have to change the value ? Can gibe me someone a hint ? In this thread or per pm ?

Thx lg blue

Gotcha....now on to some results.

I used DDU and did a fresh install of the latest Crimson driver. I didn't even open the Radeon Settings. The only change I made was to set the graphics profile to optimize for performance. I ran two runs each of Valley/Heaven/Firestrike/Time Spy/The Division. I ran them on both of the bios that are available. One is supposed to be 1220/1750 the other 1270/1750.

Bios A Warning: Spoiler! (Click to show)

Bios B Warning: Spoiler! (Click to show)

While running each I saw the card boost to the max of 1270(I will have to say that it only happened in Time Spy, and in the CPU test. Otherwise the card was hovering around 1200mhz. Temps maxed out around 66°(C), so it's not thermals hitting the performance.

Bios B did seem to give me better results in Firestrike/Time Spy, for Valley/Heaven/The Division, really not much of a difference.

https://docs.google.com/spreadsheets/d/1_9OvCU-lejR5z3A864Obgh8DPYaP5aHlKsmS2Mo1oWI/edit?usp=sharing

There doesn't seem to be that big of a difference between the two bios'. With either bios, the card really doesn't even maintain 1200 consistently. frown.gif

At this point, I'm not really sure how I feel about this card. I went in with an open mind, but to be honest, I am a bit disappointed thus far.

If there's any difference other than clocks, it's the voltage values.

It seems every partner followed AMD's values for voltages, which means every single RX 470/480 out there is running needlessly excessive voltage.

Open Wattman. Enable dynamic frequency and manual voltages, and do NOT change the power target, leave it at 0%.

Leave the frequencies alone, and open Furmark and GPU-z on the sensor tab.

Run Furmark's stress test in a 720p window, do not minimize it.

With GPU-z open you will see that you are getting a LOT of throttling. That's expected.

Back to Wattman:

Most likely, the last voltage column will have the MAXIMUM voltage the GPU's BIOS can support entered - meaning your video card is overvolted like mad. Super easy to fix:

Enter 1100 into the last column, and press Apply. You should notice GPU-z showing higher average frequencies, but that's all you'll really notice (FurMark performance will also increase, but that might be harder to see).

From there, drop down 10mv every 30 seconds to a minute. Each time you do this the frequency should increase slightly, and performance with it. You will probably be able to go as low as 1050mv, no reason really to try less than that. As soon as you have a driver reset or system crash, you know that you have gone too far - after you recover, go 15mv higher than the setting that crashed and make sure no voltage entry is higher than the new setting.

After that, while playing most games, your card will probably not throttle at all, even with +0% power limit. It will run faster and run no warmer.

RX 470/480 is a 1065mv 1.26GHz GPU all day long. I haven't seen a single example of one needing more voltage than 1050mv at 1266Mhz, 1065mv gives you margin to cover outliers.


BTW: My GPU pulls a whopping 85W average in BF4 at 1266Mhz and 1050mv, but it peaks at 115W or so, which causes throttling. +5% on the power limit stops that. RX 480 is an awesome GPU, it's just running with poor defaults.

You can't edit the 470/480 BIOS because the driver does BIOS signature validation. Don't worry, someone will figure a way around it.

You can use Sapphire's new Trixx like I do and set offsets, but you will need to manually select new profiles for gaming if you underclock. Can't wait until the new Afterburner is out, then I'll be back to using four main GPU profiles:


1: Idle/Desktop, 625Mhz RAM, 500MHz GPU, 925mv, Power Saving mode enabled
2. Light Gaming, 1500MHz RAM, 850Mhz GPU, 1025mv, no power savings mode
3. Moderate Gaming, 2000Mhz RAM, 1000MHz GPU, 1035mv, no power savings mode
4. Hardcore Gaming, 2100Mhz RAM, 1250MHz GPU, 1050mv, no power savings mode


Relative performance for each profile:

1. 7870
2. 7970
3. R9 290+
4. R9 390X+

I have found no reason to use higher clocks with 1080p, but I do have a crude overclock profile:

5. Overclock, 2200Mhz RAM, 1350Mhz GPU, 1125mv, no power savings mode

The RAM frequency necessitates the higher voltage than the GPU frequency does. I've pushed as high as 1.275V, but 1.4GHz will eventually show instability, even though my VRM and GPU temps are fine. I can gain stability by running the RAM slower, but I lose more performance than the GPU clock gains, so I settled on 2200MHz RAM and 1350MHz GPU.

I left the clocks alone, as well as the power limit. I lowered the last three P-States voltage to 1090. I tried 1085 but Valley crashed, so did the driver. I re-ran Valley after the crash and the core clock did stay at a constant 1270. Temps were fine. No improvement in the score FPS really.

Wattman Settings:: Warning: Spoiler! (Click to show)

Valley: Warning: Spoiler! (Click to show)

I had the minimum for the temps in that screen shot...the max was 66°(C) though. biggrin.gif

EDIT: Ran The Division@high settings. I did see an improvement. Warning: Spoiler! (Click to show)

EDIT II: Just ran Firestrike with the same Wattman settings....BIG difference(+680 in Graphics score): Warning: Spoiler! (Click to show)

I am surprised to see such high voltage was required. Your card may have a lot of Vdroop. Can you make a run and find the average peak voltage? I'm guessing it's dropping closer to 1050mv than to 1090mv. One of the BIOSes on my card lets me set 1035mv at 1288Mhz (stock for my card) and the other needs me to set 1065mv, but the actual voltage to the GPU is identical...

As for your performance gains: Good!

Your Valley results are better than what I had with my RX 470 (by 4%), despite nearly identical clock speeds and drivers. But that card was faulty as well.

Have you tried overclocking the memory? Before you do, use HWInfo, use the "Sensors Only" checkbox, and find the entry "GPU Memory Errors". You will probably gain more from overclocking the memory than you will from overclocking the GPU. Set your power limit to +50% for this run, you should maintain 1270Mhz without interruption. Run Furmark again, turn off "Burn In" in the settings, then run the stress test.

Now, in Wattman, run your memory frequency up to 1850Mhz, and make sure you set the memory voltage to 1000. It doesn't matter what the value is, as long as it is not set to auto (which will simply run max voltages on your GPU again for any non-stock memory clock). You should gain an immediate 5% in performance, and still see 0 memory errors. Let this run for 30 seconds. HWInfo should also tell you the VRM temperatures, they should be below 80 to 90C, though they will survive 105C without damage, you'll probably have stability issues.

If you still have 0 memory errors, bump the memory by 25Mhz increments until you start seeing memory errors accumulate (it's not unusual for one to happen when changing the clocks, so you need to watch for the number increasing). After changing the clocks, if the number start climbing by more than one or two a second, you have found the maximum setting you can actually use (yes, seriously, you can get away with tens of errors per second and still gain performance, but it's probably not the best of ideas). Error rates in games tend to be lower than with Furmark, so it's a great tool for this.

If you can max out the memory frequency and you are not getting any memory errors, you need to verify that you are getting a performance increase. If you are not, you are experiencing the same bug I always experience with the August drivers (the only drivers usable for RX 470). Your memory clocks, then, aren't actually being respected, despite GPU-z et. al. showing the higher clocks.

Memory frequency pretty much determines Polaris 10's performance. You can underclock the GPU 10% and overclock the RAM 10% and still gain performance - it's that dependent on memory bandwidth!

My RX 480 can be as much as 25% faster than stock with these tweaks. RX 470 has most of the same potential - you should be able to beat a stock RX 480 4GB with your card.

I tried your suggestions....not sure how I feel about the results really. No disrespect to you. thumb.gif

I left everything the same....overclocked the memory to 1800 and 1850 in Valley. Here are the screens shots with HWiNFO. FPS actually went down. frown.gif

1270/1800


1270/1850


I tried the same settings in Firestrike......CRASH! lmao I even lowered the memory to 1800....and it still crashes. The card also still throttles during Graphic Test 1. Graphic Test 2 and the Combined, the core clock is 1270mhz.

I reverted back to the other settings.....1270/1750@1090v. Tried to run The Division.....CRASH! I know this game has some issues...but my 970's and the R9 270X never crash.

While I would like to overclock this card, it isn't really that important to me. It's going in my son's rig to replace the R9 270X.

I'm not sure at this point what I am going to do. I've never had this many driver crashes on ANY of either of my other cards. (R9 270X/GTX 970).

Doesn't the other Crimson Driver(16.7.3) work with this card?

Final Thoughts:

I've decided to send this card back. It seems that there are multiple issues, either throttling unless the voltage is lowered or with endless driver crashes. I'm not sure who to blame, AMD or Powercolor. Perhaps it's this particular card.

I bought this to replace my son's R9 270X, and I just don't feel comfortable enough installing it on his computer. I had held high hopes, and while it does/did offer a modest improvement over the R9, I just don't feel the risk it worth the reward. frown.gif

I mean the temps are great. The color seems richer than my GTX 970's. The power usage is also a great deal better than either of my 970's and the R9. It just doesn't make up for the fact that without a lot of tweaking this card is very unstable. I know it was only 199.99, but I at least expected stability. Maybe I just got a lemon. At least that what I keep telling myself.

Thanks looncraz for the guidance and help. +1 Rep
