How many volts do i have?

post #1 of 9
Thread Starter 
Hey, how do i find out how much voltage is going through my memory/RAM?

BIOS seems a little weird because it has a fixed volts thing, volts are not fixed, they cant stay the same all the time..CPU-Z reads i have around 1.44-1.47 volts on the CPU and BIOS just says 1.400V... a little inaccurate, so i don't trust BIOS..

Anyway yea i need to know how many volts RAM is getting?!

Thanks

Perhaps Shamino has some pics on the where/what to probe to test for those @ vr-zone.com.

Why? The "number" doesn't matter, only their speed and stability does. I'm sure you can find a a method to check for your MOBO, but why bother? Memory overvolting doesn't work like CPU overvolting. With a CPU, the more volts the more you can overclock it. With memory, there is an "ideal" voltage, more OR less volts than "ideal" will be less stable. A good starting point is the manufacturer's recommended Vdimm.

erm i was under the impression that more volts allowed you to push a little further, also stabled it better when OCing to a certain point?

Not with memory. More volts will help, up to a point. After that, still more volts will be worse.

It's usually the Vdimm one.

Right peeps, For a start voltage does matter.

The DDR Spec for voltage is in the region of 2.6-2.8v.

I would download ASUS probe, this should tell you all the voltages that you need to know.

What are the part numbers located on the DDR chips themselves?

If you could provide a bit of info about your memory modules we might be able to help you get the best out of them

Take my modules for instance, They are of the type that require higher voltage than the DDR spec.

Ive run mine at 2-2-2-5 @ DDR400 with 2.8v (max speed at DDR Volt Spec)

But to over clock I need to increase the voltage to allow the operating frequency to be increased.

Here is an idea of the relationship for my modules

DDR400 = 2.8v (2-2-2-5)
DDR400 = 3.0v (2-2-2-0 or 1.5-2-2-5)

DDR415 = 2.9v (2-2-2-5)
DDR415 = 3.1v (2-2-2-0 or 1.5-2-2-5)

DDR430 = 3.0v (2-2-2-5)
DDR430 = 3.1v (2-2-2-0 or 1.5-2-2-5)

DDR450 = 3.1v (2-2-2-5)
DDR450 = 3.2v (1.5-2-2-5)

DDR480+ = 3.3+v (2-2-2-5) (requires better active cooling than I currently have)

These are mine so do not use these for your modules, as all modules are different and you could damage your hardware if not careful.

But what it does show is a good relationship between speed/timings/voltage
