Windows 10: Wrong Graphic Memory Clock

Hello everyone,
I have notice that my Maximum Memory clock is 6000mhz rather than 12000mhz according to Passmark.com benchmark. No matter what l do, memory clock does not go over 6000mhz. I have MSI GTX 1650 Super Ventus XS OC Edition.
Please help me figure out this problem thx. I suspect that affect my fps. Last but not least, graphic card does not show RPM speed of fan operating. thanks

I forget to mention that Graphic card its been always like that and OS build is 19041.572

Clock displays wrong time

I suggest you to follow the below steps to change the settings of time and time zone:

• Press “Windows+X” and click on “control panel”.
• On the left hand side click on “clock, language and region”.
• Click on “change time zone”.
• And then click on the tab “internet time” and click on “change settings”.
• Check the box “synchronize with an internet time server” and also select the option “time.windows.com” from the drop down and click on “ok” and check if the issue persists.

 

HD4850 incorrect memory clock

Ok, let's see something. Using AMD Gpu Clock Tool to set memory clocks, for all tests.

Using AMD Gpu Clock Tool to check clocks.

Memory set at = Reports at
399.9MHz = 396.87MHz
400.1MHz = 400MHz
401MHz = 400MHz
402MHz = 400MHz
403MHz = 400MHz
404MHz = 403.12MHz

421MHz = 418.75MHz
422MHz = 421.87MHz
423MHz = 421.87MHz
424MHz = 421.87MHz
424.9MHz = 421.87MHz
425.1MHz = 425MHz

AMD GPU Clock Tool reports memory clocks in 3.12(5)MHz steppings. So you can throw out my previous statement on it's accuracy.

------------------------------------

Using Gpu-Z Graphics Card Tab to check clocks (Memory clock listed right under the Driver Version)

Memory set at = Reports at
399.9MHz = 399MHz
400.1MHz = 400MHz
401MHz = 401MHz
402MHz = 402MHz
403MHz = 403MHz
404MHz = 404MHz

421MHz = 421MHz
422MHz = 422MHz
423MHz = 423MHz
424MHz = 424MHz
424.9MHz = 424MHz
425.1MHz = 425MHz

Gpu-Z Graphics Card Tab reports the locked/3D Memory clock to the nearest MHz. Great

------------------------------------

Using Gpu-Z Sensors Tab to check clocks (GPU Memory Clock)

Memory set at = Reports at
399.9MHz = 375MHz
400.1MHz = 400MHz
401MHz = 400MHz
402MHz = 400MHz
403MHz = 400MHz
404MHz = 400MHz

421MHz = 400MHz
422MHz = 400MHz
423MHz = 400MHz
424MHz = 400MHz
424.9MHz = 400MHz
425.1MHz = 425MHz

Gpu-Z Sensors Tab reports memory clocks in 25Mhz steppings.

------------------------------------

Benchmarking with Furmark

750/400.1 - 1545 o3Marks
750/424.9 - 1641 o3Marks (+6.2% increase over 400.1)
750/425.1 - 1654 o3Marks (+0.8% increase over 424.9)

What can we conclude from this?

1. Gpu-Z Sensors Tab is obviously reporting incorrectly.
2. Maximum margin of difference between actual and reported memory clocks is around 3MHz.
3. I am probably wrong about something and/or my methods are horribly mistaken.

Chime in if you got any other ideas...

 

GPU-Z is showing the wrong clocks

Last GPUZ that show correct clocks on my GT 240 was 0.3.9. I suggest you try it, and find if it is your case also *Smile

0.40, 0.4.1 and 0.4.2 report wrong clock for shaders.
