Ram of 1333 mhz with 1600 mhz ?

It may depend on your chipset whether these can be reported. Click the gear in the bottom right of the Sensor panel and check to make sure all the options are checked.

Clearly the RAM specs show that the module can run at either voltage, and is compatible with either voltage.
And this is the first time I've seen that also.

Can we see the model number of the module?

The possibility that Samsung has come up with RAM that can switch voltages as needed is a huge advance, at least for people who diagnose PC problems!

Normally (old RAM), a variation in RAM voltage of just a few tenths would start throwing up errors. If they have come up with an inexpensive way to get RAM to perform normally at varying voltages that would be a huge benefit to portable devices.

What do you fellows think?

Apparently, it's been around for quite some time. I suspect the topic never came up because the reporting software didn't recognize it. Or the OEMs thought they could charge more for lower voltage RAM and kept it quiet. But I agree, the voltage has always been a critical factor when choosing memory modules.

Yeah, I'm curious why the OP blacked-out the model number. Maybe patent problems?

That's why I like this forum.
Always learning something new!

I afraid from the hackers lol

HMT325S6CFR8A-PB
M471B5273CH0-CH9

I don't care about RAM 1600 MHz works at 1333 MHz, because my old one is 1333 MHz and the seller gave it to me the same price as 1333 mhz.
The seller and another repairer told when I asked them about the voltage , they always mix the voltage, frequency, the model and never had a problem !

Most RAM is dual voltage, is it not? That's what the XMP profile in mine does:



Mine is rated for 1.5 Volts on regular JEDEC use and 1.65 Volts on the XMP profile. I thought all RAM was this way...

Not that we've seen on this forum over the years. A lot of people had trouble with wrong voltage RAM causing no-boot, and mixing RAM voltages throwing up all kinds of odd problems.

But now that you mention it, there has been a noticeable drop off of these problems being posted in the last couple of years. So maybe as more new PCs and modern RAM enters the mainstream the less we hear of these problems.

As far as XMP, most manual overclocking of RAM is done by a process that includes tweaking voltage, so that does not surprise me that an XMP profile would bump up RAM voltage automatically.

This is true. My motherboard does not do XMP. I have to tweak the speed and voltage manually. I see your point though. I thought all RAM was multi voltage because of the dual nature of my sticks. But then, I've always used Mushkin and they're advertised that way. I'm sure that there must be other RAM that is recent and marketed this way, as well. I've just never noticed that RAM was made with one voltage.

I've learned something. Thank you.
