Does your RAM clock speed limit it at 800Mhz instead of the potential 3200Mhz?
Does your RAM clock speed limit it at 800Mhz instead of the potential 3200Mhz?
I observed that my RAM clock speed was limited to 800Mhz, and since my GPU was also restricted to 800Mhz or 400Mhz, it affected the overall performance even though it could have reached up to 3000Mhz previously.
Laptop:
Lenovo IdeaPad 5 2-in-1 14"
_OS : Windows 11
_Specs :
CPU : amd ryzen 7-8845HS
iGPU : amd radeon 780m
Memory : 16GB Lpddr5x 6400Mhz (soldered RAM)
Storage : 512GB SSD nvme PCIe gen 4
The machine is essentially brand new (I purchased it in January at the Lenovo store).
Here’s a summary of actions taken before the issue arose:
_I installed msi afterburner and RTSS (I’m not sure about them since I recall seeing a memory clock around 2000Mhz on the afterburner).
_I performed an update for AMD software.
_Lastly, I ran a clean installation with Bitdefender Optimiser (which caused odd cardboard boxes to appear on my app icons).
After these steps, I noticed that both Afterburner and CPU-Z indicated my memory clock remained locked at 800Mhz during games and stress tests.
What I attempted so far:
_I ran a factory reset and a fresh Windows installation plus a BIOS reset.
_I reinstalled all drivers from the official Lenovo website.
_I turned off VBS.
Here are the readings from AMD software, MSI Afterburner, and CPU-Z._
Update your update with complete system hardware details and operating system info. Add PSU specifications: make, model, wattage, age, condition (original to build, new, refurbished, used). List all connected peripherals. Show relevant CPU-Z screenshots for reference. Post via imgur (www.imgur.com > green "New post" icon).
I observed that my RAM clock speed was limited to 800Mhz, and since I had an iGPU, my VRAM clock speed also stayed at either 800Mhz or 400Mhz, despite previously reaching up to 3000Mhz.

After all these steps, I noticed that both Afterburner and CPU-Z showed my memory clock stuck at 800Mhz during games and stress tests.
Things I attempted so far:
_I ran a factory reset, downloaded Windows from scratch, and reset the BIOS.
_I reinstalled all drivers from the official Lenovo site.
_I turned off VBS.

Welcome to the forums, newcomer!
You should've include the SKU to your Lenovo IdeaPad laptop. Using the serial number on the bottom of the laptop on Lenovo's support site, have you seen if the laptop is pending any BIOS updates?
I did a factory reset and a clean download of windows plus a bios reset.
So you reinstalled the OS after recreating your bootable USB installer for the OS, installing said OS in offline mode? Later manually installing all drivers in an elevated command?, i.e, Right click installer>Run as Administrator?
Moved thread to Laptop Tech Support section from Memory section. Merged threads, please stick to one thread to keep thoughts concise and on topic.
some programs might interpret it as 800mhz its standard.
what 6400 stands for is the transfer rate. not the clock speed.
consider testing with hwinfo 64
HWiNFO Download v8.40
installing HWiNFO64 will offer deeper understanding of your PC's components. this tool delivers comprehensive data on your OS, storage, RAM, CPU specs, memory speeds, and thermal metrics. perfect for tracking system status and efficiency.

apply significant stress on it
for instance:
a DDR5-6400 memory package could have a controller clock speed of 800 MHz, yet this does not imply the memory operates at that frequency. the 6400 MT/s value indicates data movement rate, not the controller's internal clock.
I believe there is some confusion in what you're observing. You should be checking the GPU VRAM clock speed, not your RAM. The base memory clock frequency for the Radeon 780M is 800 MHz and can increase up to 3000 MHz. If it doesn't exceed 800 MHz, it's likely because it's stuck at the base clock speed. After installing MSI Afterburner and updating the AMD software (assuming you're referring to Adrenalin), I recommend uninstalling Afterburner, removing the Radeon driver and Adrenalin, and then reinstalling Adrenalin and the driver. Check if the VRAM boost occurs normally. MSI Afterburner can cause issues if the graphics driver is updated while it's running in the background. Regarding Bitdefender's "optmizer," it seems unnecessary and likely ineffective.
It could be a software issue, but it's pretty harmless.
The best way to describe it is 3200 on DDR4 with a transfer speed and clock speed of 1600.
You mentioned seeing around 2000 MHz, which makes sense since the maximum clock would be 3200.
It doesn't always jump to the highest clock unless it's pushed harder. Also, make sure your power plan is set to performance mode or full power, not eco or normal.
Some software might read it as 800 MHz, which is why I suggested using hwinfo for accurate results.
Are you sure your RAM and VRAM speeds are aligned since you have an IGPU and no real VRAM? Here are some measurements I collected in-game, keep in mind I was stable at 60fps in ultra before the issue started, now it drops to 30 at low settings. Regarding afterburner and AMD tools, I performed a full reset on my laptop, which likely cleared them.
