[SOLVED] PnP memory

[seriouslyrobert1]

I'm buying a new Sager laptop and I thought it would be XMP, but after emailing the guy said it's not. He said the ODM is compatible with PnP only. What is PnP? I've never heard of it. And after looking on Google it seems anything related to PnP in search comes up from 6 years ago or more on ddr3.

The stock memory in this one is 260 pin 3200mhz ddr4. I bought Kingston Hyperx 32gb 3200mhz xmp to put in it. Will that work? What's the difference?

Thanks

PnP is not anything special, it merely means that it's plug and play for the SPD, serial presence detect, which contains the various encoded JEDEC profiles. XMP is just Intel's nomenclature for it's advertised speed and timings at the upper range of the SPD profiles stored on a given module. Also called A-XMP on some AMD motherboards, D.O.C.P on ASUS motherboards (Because they refuse to pay royalties in order to use the "XMP" designation) and EOCP.

Most laptops, aside from a few very high end gaming models, do not support XMP profiles, per se, but if a module is advertised as DDR4 3200mhz and the laptop or notebook in question, or the motherboard in it, supports that type of memory and that speed of memory, then it WILL auto configure itself to that speed and timings. If not, it SHOULD auto configure itself to whatever is closest, because very few laptops have BIOS with configurable memory settings. I'd find out what the EXACT model of the memory it comes with is and then we can pretty easily determine what sticks will be compatible with it from there. At least, in general.

Some memory simply doesn't play nice in some motherboards and to some degree there are cases where some amount of trial and error is simply unavoidable, although, usually most of the legitimate memory manufacturers like Crucial, Corsair, G.Skill, SK. Hynix, Supermicro, Mushkin, and Samsung will usually have compatibility lists or utilities that will specifically tell you which of their memory modules is compatible with a particular machine or motherboard.

Ok thanks. Since it was backordered I still have to wait a few weeks for the computer, so I'll email them and see if they can give me the exact model of the RAM and post it here. Then I'll have time to return the other if needed. I'll post here when I know.

Sounds good.

Sounds good.

So I got the computer today and this is the memory that it has:

Laptop DDR4

Laptop DDR4 Neo Forza DDR4 unbuffered SO-DIMM memory is the latest upgrade solution that supports Intel's newest platforms for faster data transfer and enhanced power efficiency. Utilizing a 260-pin design, operating voltage has been reduced from 1.5V on DDR3 to 1.2V, not only save the power...

After looking at it, the one I bought (hyper x) has the same specs except CL20 instead of 22. My computer doesn't support XMP and both are JEDEC compatible... so I'm thinking the hyper x will work... am I correct? The computer will be open for a bit as I'm waiting to get the ssd from Amazon within a few hours, so I'll wait for your response. Thanks.

Sorry man but I just had knee surgery so it's probably going to be a while before I feel like looking into anything. However, memory is memory. Pretty much ALL memory modules come with the JEDEC and XMP profiles imprinted on the module so there really are NOT any "XMP vs non-XMP" memory modules out there. The SPD are the standard JEDEC profiles while "XMP, A-XMP, D.O.C.P and E.O.C.P" are just the manufacturers tested and imprinted settings for that memory.

If you buy a memory module and the motherboard that memory module gets installed into supports the settings (timings, voltage, frequency) coded onto the module, then it should run at those settings. It doesn't matter if you can actually go and enable something that says "XMP" or not. There are very few laptops that actually have user configurable memory settings in the BIOS. Try the memory, if it works, it works. If not, return it and try something else. That is basically what everybody has to do, no matter how knowledgeable you are on the subject, when it comes to devices that are really not user-configurable. Or, find evidence in one of the forums or bulletin boards of a specific part having been successfully used on that specific machine, previously.

No big deal..I kind of figured that was the case. Sager isn't incredibly common, so I probably wouldn't be able to find the specifics of success for my machine...I couldn't even find a model specific tear down on YouTube.

I'm sure it'll work. I'll know in an hour when I get my ssd from Amazon and install. Thanks for the help.

Usually, worst case scenario, if your memory has specs that aren't supported, such as memory speed that is too high or timings that are too low, the board will usually auto correct their settings to timings that are compatible. In some cases, rarely on laptops, there might be big enough incompatibilities that it can't correct for them in which case a given part number might not work, but that is pretty uncommon so long as all installed memory came together in one kit.
