Overclocking Radeon VII

[Sajeev]

Hi Guys,

  Does anyone have any experience with overclocking Radeon VII? My card is not giving me a performance that I am looking for. My cinebencz scores are not great at all somewhere around 8700 on 3D Time Spy and 4192 on Time Spy extreme. My config is as as below:

 

MB: Asus Maximus XI Extreme

CPU: i9 9900K (On custom liquid cooling, 420MM Radiator)

RAM: DOminator Platinum 64GB @ 3200 MHz

Storage: NVME Samsung 970 EVO PRO

PSU: 2000 Watt EVGA

GPU: Radeon VII

 

 

Any help will be deeply appreciated. I tried doing it using AMD Radeon settings utility, global wattman but with no luck, my system completely freezes on clicking save when I try even the Automatic OC mode... Please help it's getting so frustrating...

Undervolt it. It wil lboost higher thanks to lower temps. Its stock votlage is waaaay higher than it needs to be.

How do you suggest me to do this? Can you please guide me?

There are guides on youtube that would be far better than a text bassed one.

If you have the drivers uptodate you have the option autoundervolt and then click autooc. Use amd overlay to check your clocks and gpu usage. Clocks need to be 1700 to 1800mhz and gpu usage needs to be at 99% to 100%. Also

Tks a lot, yes I have the latest drivers. I can see the Auto Undervolt option is it possible to manually load a profile and then select auto undervolt?

What is your stock voltage? I have a stock voltage of 1023mV on my Radeon VII. If yours is much over 1100mV then you will be able to overclock very little if at all without watercooling.

I can overclock my Radeon VII to 2000Mhz with about 1080-1100mV of voltage. This makes the GPU much louder during gaming (full speed fan curve 100% of the time) and the stock cooler really can't keep it cool unless you spin the fans up even higher than the default. Performance is about 10% better in games.

With watercooling it's a different story and some people have got over 2200Mhz using that. Although they did also have high ASIC quality. I can get 2185 to dial in on full fan speed and cold ambient temps but it doesn't run at that speed for long and does throttle down to 2100. With that kind of overclock benchmarks are close to 20% higher but it's unsustainable without water to cool the GPU.

 

Hope that helps a little.

Tks man. My stock voltage was 1132mV. As mentioned in one of the replies I did undervolt it and was able to get a slightly better performance. I did also adjust the fan curve slightly which made it silent. As of now I’m running at 1930MHz with 1175MHz on memory at 1080mA and so far it hasn’t crashed or have produced any kind of artifacts. With the fan curve slightly down it is a little silent now. 

 

Played Battlefield V for 30-40 mins, no issues whatsoever.. I heard bykski has a Waterblock out for this card, will try to get it and see if the temperature gows down and may be just crank up the voltage a little more to 1100mA and try to get 2000+  along with full 1200MHz on memory. Will play with it more during the weekend, 3Dmark Time Spy score of 9180 as of now.

 

Hope you could guide me a little bit more on this.

Personally I'd wait for Heatkiller IV blocks for Radeon VII, they're definitely worth it. I had one on my Vega FE and the build quality is amazing (better than the EK blocks I've had or used), performance is stellar too. With a 2700X and the Vega FE both on a loop with a 360mm slim rad inside an Enthoo Evolv (so not a very big rad, not the best case for airflow) it hit a max of 52C with both it and the CPU at 100% load for 8 hours or so. IIRC the Vega was at stock or slightly higher than stock voltages too.

Any idea when is it coming out?

According to a comment on this thread: 

A guy from Watercool (company that makes the Heatkiller lineup) said they're working on one, should be out end of March or early April.

I'm also waiting for a block. I have my eye on an Alphacool Triple 180mm which is on a big discount. I was thinking getting the EK block which was teased recently and so should be out soon (hopefully), but if Heatkiller is out first then I will get that.

Let's hope that's the case.

To all VII owners, I would highly suggest repasting and doing the washer mod to get junction temps down. It should give an extra 10c or so at similar fan speeds.
