GPU clock speeds on nVidia Ion

AIDA64 Extreme Edition Beta 1.60.1314

Laptop is an HP Mini 311-1000NR.

GPU is nVidia ion.

Under Sidebar Items regarding GPU clock speeds I have two items available;

GPU Clock

GPU Shader Clock

Both show 100MHz constantly while monitoring which is honestly useless information and I really have no idea to what it's referring. Neither of the GPU clock speed items available under Sidebar are helpful because both constantly show 100MHz as their readings.

1.) On the main page of AIDA64 under Display/GPU I see RAMDAC clock which honestly reports the GPU Core Speed. (Currently at 400MHz as I type this.)

2.) Under Display/GPGPU/Device Properties I see a Clock Rate item correctly listing the GPU Shader Clock speed currently at 1100MHz.

3.) I can not locate a working report of GPU Memory Clock anywhere although both GPU-Z and CPU-Z both show the memory clock (And core and shader) correctly.

Is there a way I can add RAMDAC and Clock Rate listed above (And GPU Memory Clock if possible.) to the items I can monitor in the Sidebar? These are the items I would like to monitor on my desktop via the Sidebar Gadget.

Thank you for your assistance.

EDIT: I have just downloaded and tested the latest beta, 1.60.1339, and the problem persists.

100 MHz clock is reported because at idle your GPU is running at PCI Express nominal clock speed (100 MHz) to save power. It is a common power management technique of nVIDIA IGP GPUs.

1) That is a pure coincidence. All modern GPUs are equipped with a 400 MHz capable RAMDAC, but that doesn't mean it has any relation with the GPU core clock at all.

2) GPGPU device properties reflect the capability of the GPU, and not the actual speed it is running at. The actual speed is 100 MHz at idle, as reported on the GPU page.

3) IGP chips (like nVIDIA Ion) usually use the system memory as frame buffer and texture memory, and so it makes no sense to display memory speed or memory properties on the GPU page. Instead, AIDA64 shows the system memory type and clock rates on the Computer / Overclock and Motherboard / Motherboard[/b] pages. You can also have the system memory clock speed and timings displayed on the Sidebar Gadget.

Sorry but I'm just having a really hard time understanding that.

Can you please look at this image?

You can clearly see and agree that while Furmark is running my core and memory speeds should be ramped up from 100MHz. In fact they are being reported by every software monitoring tool I use (Furmark, GPUZ, CPUZ, HWiNFO32, Nvidia Tools, etc.) as 450MHz and 1064MHz. Yet AIDA64 always, no matter the load, reports my GPU speeds at 100MHz.

To add even more to this no other software monitoring tool, not one single time, will ever report any of these speeds at 100MHz.

Even further, when looking at the possible clocks speeds in my VBIOS under a multitude of conditions running at 100MHz is not even an option.

Unless I'm missing something here it definitely appears as if AIDA64 is incorrectly reporting these speeds.

Can you please shed any light on this?

Thank you for your time.
