How can ram voltage affect cpu longevity.

[AshleighH42]

Hi everyone, I was wondering why and how high ram voltage can damage parts of a cpu. Anyone know?

Considering the Ram voltage only goes to the Ram and has a seperate VRM to power it. 

 

I dont see that being a thing.

 

 

You can go up to 1,45 volts pretty safely on the Ram. If you know what you are doing you can do more

Why does intel have a max voltage specification of 1.4175V and amd with a max voltage specification of 1.45V for the cpu's then?

you should not increase ram voltage on ddr4 over 1.5v and expect it to last 3 or more years

 

ddr3 around 1.6v

 

why, because voltage will kill those parts, it will not kill cpu, it doesnt use same voltage, but might kill motherboard too

BecauSe thats the CPU..... Not the ram

For the VDDR voltage intel says <=1.4175V and amd says <= 1.45V

The RAM Voltage cannot directly damage a processor. But very high RAM speeds that your CPU cannot handle can.

 

For example if you run 3600Mhz RAM on a i3-8100, the processors IMC (Integrated Memory Controller) can be damaged.

Ram frequency wont damage the IMC on a 8100. The VCCSA and VCCIO can however and these get raised with frequency if not manually set.

The only possible way i could see a CPU being damaged by ram voltage is by the small amount of voltage that the ram sends to the CPU as data. I guess these signals would be of a higher voltage which could possibly damage the IMC on the CPU. I'm not certain about this though, feel free to correct me if I'm wrong.

Then thats what they advertise. They allways put in safe levels

 

Also unless you knlw what you are doing. You wont get any past that (any performance)

Dont run over 1.4V i'd say.

Don't be rediculous, those voltages are sub 1V and won't do anything.
