Hello guys! 

Earlier today, i saw a guy claiming that installing fx 32 GB of RAM (4 x 8 GB) in four slots, with one GPU would mean that the effective RAM of the PC would be 16 GB. Meaning that in order to get 32 GB effective you'd need a second GPU. However, i've always been under the impression that RAM would be system wide, and mostly accessed by the CPU? So that that the effective RAM doesn't depend on how many GPU's you have installed. 

Am i being dumb here? Or does anyone know what he might have meant?

For example the old i7 950 supported 24gb of ram the 7700k supports 64gb.

Thanks guys, good to see i still know my stuff. The 8x8 should've been 8x4, oops :P

or two

You mean one or multiple RAM sticks? 


Defective RAM would most likely just prevent the PC to boot as long as the defective RAM is still installed.

8x4 means you could run your RAM in quad channel, and it is not affected by amount of GPUs

GPU vram is framebuffer and is GPU only, while RAM that your system uses is for the CPU

Well, if you have say, 8x4 sticks, and one is defective then you would need to remove the defective stick, meaning you would only have 24 GB effective. The PC would most likely not be able to boot, with a defective stick of RAM.

the guy is on drugs; having one GPU doesn't cut effective system ram to half. with that logic folks without a GPU wouldn't be able to run their computers at all. it only applies to SLI/crossfire where effective vram remains at say, 8gb even if you have 4 8gb GPUs.

There is system memory (RAM) that is used exclusively by the processor

And video memory (VRAM) that comes with your graphics card, is used exclusively by the graphics processor

 

Total RAM quantity depends on what you have installed, and can be replaced or upgraded as you like. The maximum amount the system will recognize, is determined by the motherboard's limitation and operating system. There are single sticks of RAM that can have 16GB each. Some motherboards also have only two RAM slots.

 

Total VRAM quantity is determined by the model of graphics card you buy. It cannot be upgraded. If you run two graphics card together (SLI for Nvidia and Crossfire for AMD), it WILL NOT double the effective amount of VRAM.

Yeah, this is what i believed as well - just wanted to make sure i wasn't the odd one out! :D
