Ok so from my previous which to buy thread(which got kinda way off topic so starting this new one) I bought an Asus Rog Strix Vega 64 OC.

So the advertised boost clock on the card is 1590Mhz. Which if I don't screw with Wattman the card never gets close to. In games if I use the cards built in settings of Gaming or OC the card is only getting to around 1350-1380 on average.

So I compare this to tomshardware review of the card. I use a computer case but normally have side panel off.
Their test show that during gaming speed settles around 1360Mhz which is on par with mine. But their open test bench temps are 75C while I have never seen mine get over 65C. And at these temps the fan is only 2300rpms so they are actually pretty quiet to where I can't hear them when gaming at all.

My questions are, how much should I be changing to actually get higher speeds from the card?
I don't really care about saving power so undervolting really doesn't matter to me.
I did some screwing around in Wattman and changed the power limit to +50%. At this point the wattage from the card is around 310-320. Speeds do get up to high 1400s and maybe hit 1500s occasionally. Temps still not getting into the 70s. And this is changing the Stage 6 and 7 up to 1700mhz,

The card hasn't had any issues running with any of these settings. so I am just curious what the best way to go about setting everything at would be.
Is it normal for most games to not get near the boost clock advertised speed?
Also I was under the assumption this card was known to run at 75C for temps. Is my temps in the 64-65C an anomaly or is that normal?
And I notice sometimes when not gaming the speeds of the card are not dropping below 1100Mhz. Which seems weird but the temps do drop to like 23C. Is that normal for it to occasionally still operate at higher speeds?

The last question I have would be based on Wattman vs Asus GPU Tweak II. Are they over riding each other? Is one better to use than the other? Gpu Tweak gives me much more options as far as fan control and such. But I just feel like when I restart the computer that Wattman is just going to go back to its default settings.

Have you set the "Performance/Watt Profile" to Power Saver?

I like WattMan a lot. I'd suggest just using that. AMD Settings is already running in the background anyway.
[Add] Mine must be an isolated case, but for the better part of a year and over multiple driver updates, WattMan dumps my undervolt settings and goes with default voltages on startup. Every time, and applying my undervolt profile does nothing. Restarting my PC fixes the issue. Just something to check.

I have no experience with Vega cards so this is just speculation -- but does the card / driver / Asus software have a profile system for setting clocks vs. fan speed? It may be defaulting to a "quiet" profile rather than a "Max" profile.

You may have to undervolt the GPU a bit to get near its max boost speed. My unit is able hit it with 1.050 vCore. Vega benefits much more from overclocking the memory though.

What would you say i should try for memory speed wise? It's currently 950.

And what speed are you using for state 6 and 7

Under-volting should matter to you because that is the only way to achieve higher clocks usually! I started with my Reference Vega⁵⁶s (running 64 BIOS) using WattTool & OverDriveNTool to set P6 & P7 voltages to 1125 or 1150mv and HBM to 925-950mv with power+30-50% I think for gaming. I think those worked good for me. Right now I mostly mine a do light gaming at the same time (Ages of Mythology Extend Ed.) running the the GPUs @1150Mhz/950mv HBM2 1100Mhz/900mv and power -30%. I put Alphacool watercooling on my Ryzen & 2 Vega⁵⁶s, so pushing them to around 1600Mhz in benchmarks isn't a problem. With the Reference blowers, I had to jack up the fans to about 80% (with under-volting) to keep them up around the low 1500s. The early Wattman issues have been pretty much solved, so you should be able to use that to under-volt your card. I know the speed of the HBM2 would drop back down to 800 if it started getting too hot usually around 80C. Hopefully your Vega has cooling capacity to reach 1550-1600 when under-volted.

I just wanted to echo what others have mentioned about Wattman and undervolting. Wattman really does work well nowadays, and undervolting is pretty much the only way you are going to hit near boost clocks on your Vega without resorting to watercooling. You hit temp/voltage limitations on the chip even when using the stock 'Balanced' profile. AMD has pushed voltage way up on their last few gens of GPUs to get performance and yields up IIRC. I don't know how much different the Strix cards are from reference, but my reference Vega64 (with Morpheus II/fan mod) does ~1580MHz at 1630MHz/1030mV P7 state. I've run HBM as high as 1150MHz on mine, but I keep it at 1080MHz now. I set a max temp or 68C and a target of 48C (I don't mind the noise my fans make). I'll try and post a screenshot of my settings later if I remember.

Undervolting wouldn't be a necessary part of this if AMD's stock voltage/frequency curves were sane, but they aren't.

On my RX 460 (power only through the PCIe slot so the power limit has to stay strict), stock was 1040-1090 mV and 1060-1100 MHz (I forget the exact numbers but within 10 of those), and the actual limit turns out to be more like 945 mV and 1185 MHz. That'd leave no safety margin on it, but 1165 is comfortable and noticably faster than stock for the same power consumption.

It'll be worth knowing there's a sharp knee in the voltage/frequency curve at 945 mV (everything on GloFo 14nm has got it), past which it takes a lot more voltage per clock increase. You'll probably want to go well above that, but seeing what kind of frequency it'll handle at 945 is still a good start.

On my Sapphire RX Vega 64 OEM AC, I've set up a custom undervolted profile that runs with the following settings:

- Cores at default speeds
- P6 1050 mV, P7 1100 mV
- HBM 1000 mV at 1080 MHz
- Power at +15% (same as the Turbo profile -- ~255W)
- Fan speed at 400-4900 RPM (sounds like a hurricane, but it works)
- Temperature target down from 75-85 to 70-80 as the HBM tends to get unstable if it gets above 80 degrees for me.

The above settings yield +10% performance from Turbo at the same wattage, meaning it is basically "for free".

You can experiment with downclocking 1-2% at the same voltages as it won't lose you a lot of performance. My card sits around 1500-1535 MHz in Unigine Superposition 4K and a little higher at the 1080p Extreme preset.

I think it's important to point out that WattMan makes it really easy to adjust the performance of your GPU depending on the game you're playing by being able to set voltage/frequency profiles for individual games. I have an RX480 driving a Samsung CHG70 2560x1440 @ 48-144Hz FreeSync and there are plenty of games that I've tuned my card's max frequency down closer to 1000MHz (from default 1300MHz) to save gobs of power/heat and I can still get >100fps. Not to mention that Target Framerate Control, Power Efficiency, and Chill will do that for you automatically on your "general" voltage/frequency curve. Gotta give kudos to AMD for turning a negative (more power-hungry GPUs) into a positive (better control over power usage). Not all games require your GPU to be running full tilt.
