RX 580 idle memory speeds problem.

[HristoBB]

Hey there guys. I have a slight problem with my RX 580 Sapphire Nitro +. The problem is that the memory clock always stays at 2000mhz which is the stock max clock for the memory. I'm also using overclock profile for 2100mhz which will sometime trigger the fans and they will ramp up for a couple seconds and then stop. My case is well ventilated,but still my GPU is staying at around 50 to 53 degrees at idle with fans stopped which is a little bit high knowing that i have direct airflow with 200mm fan on it. 

I'm currently using 2 monitors. 
27 inch asus 144hz 1ms 1080p and 21 inch Philips 60 hz for monitoring temps and facebook. 
Asus is connected through HDMI and the Philips through DVI. 
Whenever i disconnect the HDMI cable and leaving only the second monitor on the memory clocks will return to normal idle state at 300mz and the GPU temp will drop to around 37 to 40 degrees. (The cooling block is also making contact with the memory modules so when they heat up it heats the gpu even tho it is not used) 
I've tried lowering the refresh rate although that if it even works it's not a permanent solution cuz i'm not willing to sacrifice 144hz,but it didn't work. 
For now only completely removing the HDMI cable from the Video Card works. 
Any ideas? Should i switch to display port instead? 
And i've just bought the Asus monitor,but before that i was using Panasonic 32 inch TV and the clocks were the same 2000mhz all the time... also using the HDMI for it. So maybe it is the HDMI that's causing this problem after all?

And why is this a problem? Memory overclocking on the 580 very rarely produces any noticeable framerate improvements at the cost of increased heat, increased power draw, reduced stability, (sometimes) and the reduced lifetime of the card...

You might want to redo the thermal paste. I had the RX580 Sapphire (still running in my mediaserver now) and it was hitting 81ºC under heavy load... replaced the thermal paste with some decent arctic silver and saw anything up to an 11ºC drop in average temps.

 

Also, my memory would go to 2250... but could only get about 80mhz out of the core.

FYI, don't use that on GPUs. It dries out too fast, and it's electrically conductive. (meaning it can short things out and cause permanent damage) Use something non-conductive that won't dry out, like Prolimatech PK-3. (it also has better thermal performance, and is less expensive, so better in every way)

I just used what was at hand, I'm careful when applying it as I remember the days of yesteryear when there were bare dies on CPU's and you'd actually spread the paste on the cooler not the CPU. You used to get a straight edge in the pack with the paste to allow you to get a thin even covering.

I know how that goes, but I'd suggest switching it when you can. (if it's been more than a year, it may be overheating without showing on the temp sensor)

Well the old RX580 is now in my mediaserver and the only reason I put it in there is because the previous R7 280X couldn't do 4K 60hz (only 4k 30hz) and I'd upgraded the TV earlier in the year. Temps are fine and it's never actually pushed above idle. The entire system is just used to stream media to other systems in the house.... and aside from the occasional bit of transcoding which the CPU handles... the GPU never gets taxed and the fans normally spun down. So it's never been pushed hard enough to get hot and come close to drying out the paste.... I've never really had a problem with AS before.

I've changed my thermal paste recently since i have this card for almost 1 year now,but didn't notice any improvements. It wouldn't go to 80 degrees in the 1st place. Max i've seen is 72 to 73 and with a custom fan profile it never goes over 65 and stays pretty quiet aswell. 
And with memory of 2100 and memory timings at level 2 i'm getting 5 to 10 fps more in most game.

So what is the concern? That the VRAM keeps defaulting back to 2000mhz?

Yes and that's keeping the GPU temps at 50 degrees when they can be at 37-38 if the ram is defaulting at 300mhz. 

Not that it's a big problem,but if it can be resolved why not?

What are you using to OC the card?

AMD Radeon Settings.

AMD uses a variable speed for EVERYTHING. You only get to set the maximum limits, and the GPU controls when to speed things up. You have to put a significant load on it to see what you're actually getting out of it.

I don't think that's true because when i disconnect my HDMI cable Memory speed goes back to 300mhz and core temp is going down to 37-38 instead of 50.

It's been like this since a long time. If you use 2+ monitors the memory clock runs at max(my HD7770 from 2012 does it too).

Jesus that's terrible actually i've never had such a problem before with Nvidia,but i guess i'll have to live with it. I guess that it for this topic... Thank you
