Do you want to limit the refresh rate of your monitor or the in-game FPS? The in-game limiter limits your monitor's refresh rate, which isn't generally a good thing. Nvidia control panel limits the in-game FPS but not the refresh rate -- which is usually the better way to go (and it's what I do...

Thanks JayGau and TerryLaze, I'll try copying the mp4s and avis directly to the HDD and see if that makes any difference in the stuttering playback.

I wasn't planning on ever connecting this laptop to the internet, but I was hoping it would at least be good enough to play movies (mp4s, avis) for my mom off of a USB stick. I was surprised and disappointed to find out 4 GB is the maximum amount of system RAM that can be installed on this laptop.

@Eximo, I noticed when you used to be able to directly mod Nvidia vBIOSs for Maxwell that there were four (aside from the VRAM frequency) clocks you could modify: PC=core clock L2C= cache XBAR= crossbar SYS=system. Are these four frequency domains still present on modern Nvidia GPUs? If there is...

I was attempting to stream an mp4 movie for my mom off this laptop via a USB stick to her rear projection TV. The only other laptop I have available is even older and slower than this one (and doesn't even have HDMI output).

Thanks Eximo, your answer brings up almost as many questions as it answers. Maybe each SM has its own MMU and they each communicate w/each other over some sort of bus? Maybe if each individual SM MMU controls a specific address space then if another SM MMU needed data from that address space it...

It's an old laptop, but when I try to stream even sub-1080p content it noticeably lags to the point of dropping frames. While in operation it typically has roughly 1 GB of free RAM. It's also using readyboost. It could be it's hitting the pagefile hard because of the limited amount of RAM and...

That's obscene. That's what I paid out the door for my 4090 (thanks microcenter). R U sure those prices aren't for 4080 supers?

How much of a diff. in perf. will there be once Nvidia tunes their drivers for 5xxx cards? I found it interesting that the 5080 occasionally beat the 4090 substantially in 1% lows (I think it was 1% lows).

According to this https://forums.developer.nvidia.com/t/what-is-cores-per-sm/29997/4 Cuda cores are part of SMs. So do SMs provide individual MMUs over a 32-bit memory data bus to specific VRAM ICs? Or is there an independent MMU that accesses all VRAM for the individual SMs using some sort of...

@DS426 Are there really GPUs that can make use of a 384-bit, GDDR7 memory data bus? GPUs only run at 3+GHz. right?

I'm guessing the CPU on-board sensors are probably pretty accurate but how accurate are motherboard temp and voltage sensors? I'm guessing manufacturers don't test each and every motherboard temp.&voltage sensor before issuing a QC approval?

Will the prices for 5090s ever come down? I can't help but notice the 4090s seemed to actually go UP in price at the end of their product cycle -- at least at the retail level (i.e. MSRP never seemed to change).

I've read that the US military still uses core memory in some key systems because it's resistant to EMF bursts.

For DDR4 I've read that dual rank has some perf. advantages over single rank, but single rank can usually clock higher. Is there any advantage/disadvantage to single rank vs. dual rank for DDR5?
