GTX 1080 Ti Strix running at 1480 Mhz??

[Fabian H.]

Hi guys,

 

i just build a new computer and got myself a gtx 1080 ti strix oc. I'm new to overclocking and so on, but the card is advertised to run at 1590-1700 (depending on the mode) mhz out of the box. And most people report seeing clocks of over 2000 mhz with slight overclocking.

Using furmarks gpu stress test, my card seemingly runs at only 1480 mhz and memory at only 5500. Why? Is there something i'm overlooking, like a bios setting for example, or is my card not working properly?

Drivers are up to date (latest in geforce experience), but other than that i'm a total noob and you should take nothing for granted 

 

Thanks in advance,

Fabian

increase power target in msi afterburner and check your temps

[Jurrunio]

Do you use any overclocking utility, like MSI Afterburner?

What does it run at in games? Furmark is a pretty worse case scenario that you won't encounter while gaming.

@Jurrunio I am using GPU Tweak II. According to that, in OC mode, the card should run at 1700 gpu / 11000 memory. 

 

I just found out that the card actually goes higher than 1480 mhz, when i increase the anti-aliasing in furmark. With anti aliasing maxed at 8x, the card reaches a seemingly healthy 1961 mhz gpu clock. However the memory clock is still at 5500 mhz. Is there something im missing? Shouldnt the card try to use its full potential to reach the highest fps it can, even without anti aliasing? Or is furmark just not a good tool to test the performance?

 

Edit: @DocSwag ok, what other tool would you suggest?

The memory is right, it's technically 5500 MHz vram, but because of DDR (double data rate) it's technically 11 ghz (which is what Nvidia advertises).

 

Furmark isn't the best tool to test, since it's wayyyy more intense than you'll ever see. What are clock speeds like in games?

[Fabian H.]

Ok, i seemingly just overreacted because of Furmark showing silly values. In games it went to 1962 and 11008.

Thanks for showing me wheremy mistake was. Should have just checked in a game to get a more solid result  

 

Technically this solves my problem. I'd still like to know why Furmark would only use 1480 mhz, especially if it is "way more intense than you'll ever see"? Shouldnt it use as much of the available performance as it can then?

 

Sorry for causing you guys troubles over such a silly mistake.

Nvidia's GPU boost dynamically boosts the GPU's frequency based on temperature and power consumption. When you run furmark the GPU runs a lot hotter and more power hungry than normal so gpu boost pulls back the clock speeds in order to keep temps and power consumption in check. If you wanted to see higher clock speeds in gaming as well, you could use something like MSI afterburner to increase the power limit, which might make the GPU boost a little higher.

 

Also, remember to quote people in the future, or they might not see you replied!

Oh, thanks for the advice.

However, if what you said is true, then using the same settings that ran at 1480 mhz without antialiasing, with 8x anti aliasing should NOT result in the graphics card clocking at 1961 (like in games), should it? But thats what happens.. so .. i'm confused.

 

Edit, To make things more clear:

Furmark 1440p 0x anti aliasing = runs at 1450-1480 mhz, using ~<80% power

Furmark 1440p 8x anti aliasing = runs at 1961 mhz using ~90% power

Yeah true, I'm honestly not too sure why increasing anti aliasing made it go up to 1961 MHz
