Graphics, vs Memory, vs video clocks?

[Snowarch]

my nvidia driver, heaven benchmarking tool, and green with envy linux gpu overclock utility are giving me diffrent results about my P104-100 with gddr5x memory, and all 8gb vram. I know the heaven score can't be accurate cause my gpu can handle both minecraft with raytracing shaders, at 30-21 fps depending on the settings, and its beating my p106-100 by over 30%, in the heaven benchmark which corresponds to 1070 vs 1060 %'s or just about. i want to overclock, but i don't know which clock is which. please explain. 

 

the video vs gpu is the most confusing part, but why is everything, but the driver seeing memory speed diffrent?

 

system is one in signature.

 

 

 

nvidia driver: 10,000 memory clock, 1905 boost, 1885 usual gpu clock

 

Green with envy

graphics: 1704 boost 16xx clock base

video: 1905 1885/1887 usual

memoey clock: 5,500

 

Heaven benchmark

speed: 1885 mhz

memoey clock 5,500mhz

score: 2000

Just don't mess with it. Nvidia cards will autoboost themselv s so the less things you touch, the less chance you create a problem or problems

i still need to activate coolbits to even access the ability to try and change anything.

 

i'm getting 55-65% fan speed max with 70 degrees under heaven and or supervision benchmarks, everything else only stresses it to 55 degrees. only 90 watts of the 180 possible are being used under max load (70 degrees the fan speed 65%-) according to green with envy. i want my fans to go a higher speed at 70 degrees. theres a slight throttle because of reaching 70.

[Snowarch]

 according to the nvidia driver, 1885 instead of 1905 speed. think its throttle. with that in mind, is it okay to increase the fan speed when it hits 70 by 5%?

 its bearly in the yellow temps, maybe by a few degrees or so and suggests throttle. small throttle but still. that temp is at 100% gpu usage. my psu is 750watt corsair gold (rm750) so i think i have the voltage to spare just for fan speed not sure.

If you manage to get 1905 MHz instead of 1885 MHz, that's literally 1% faster (1905/1885 = 1.01). It's not going to make much of a measurable difference in terms of speed, but might run hotter, louder and require more power for next to no gain.

Nvidia's driver is showing you the effective clock rate. The benchmarks are giving you the physical clock rate.

 

DDR = Double Data Rate, which means memory can do two operations per clock. This means memory clocked at 5000 MHz is effectively as fast as non-DDR memory running at 10,000 MHz. Manufacturers usually cite the effective clock rate, because it sounds better. Lots of tools will show the actual clock rate.

@Eigenvektor thats the thing. video and graphics clock. which one is my gpu using? why is the video so much higher?

1905 boost (video) vs 1704 boost (graphics)

 

and even if i don't overclock (these clocks i mentioned are all stock) is it safe to make the fans run a little faster earlier? i don't like the 70. i know its technically safe but feels high compared to old gpu (53 degrees max)

I think I found your answer here: https://developer.download.nvidia.com/compute/DCGM/docs/nvidia-smi-367.38.pdf (Page 16)

• Graphics: Current frequency of graphics (shader) clock.
• SM: Current frequency of SM (Streaming Multiprocessor) clock.
• Memory: Current frequency of memory clock.
• Video: Current frequency of video (encoder + decoder) clocks.

In other words, it's using all of them for different parts of the graphics pipeline. I would assume "Video" isn't that important while gaming, unless you're recording a stream, while everything else is used.

Sure, but don't expect temps to go down by much. My RX 480 is also around 70° under load. Ramping up the fans doesn't drop temps by much but increases noise a lot. The one downsize to ramping up fans would be that they potentially wear out sooner, which means you might have to replace them at some point.

coolbits wont enable anyways, and i just pulled up green with envy. i was wrong. graphics is what has 1911 boost. video has the 17 thing. 

 

my gpu draws 90 watts at load 100% utilisation, even tho its getting full in game performance, and says pcie x4 in the driver, Gwe says it can use up to 180 watts max, and doesn't say the pcie. is that inaccurate? beating my p106 that ran at x16 by 30% heaven score wise.
