The only special thing about PnP memory is that it's more likely to run at its rated speed by default, at least in an Intel-based system. DDR3-1600 often defaults to 1333, but all you have to do is change the settings to 1600. So it's a pretty minor change. In practice, it's just another set of RAM. And DDR3-1600 CL9 is about as average as it gets these days.

First the mobo determines the default boot freq, not the DRAM....and No, nothing special about these, they are plain jane 1600/CL8/1.5 sticks (entry level for current Intel systems), I would rate them as better than the Kingston Hyper X sticks that Kingston has that are rated 1600/9 and 1.65 - but by far the vast majority of 1600 sticks made are CL9 and 1.5

Not if the mobo itself defaults to 1333...the info in the SPD is info that's provided to the BIOS, if it works into the BIOS profile then it's used else the mobo defaults to it;s own settings gen 1333 9-9-9-27 and with some of the newer Z87s 1600 9-9-9-24 or 27, though many default to 1333

idk but my motherboard supports "plug n play". I don't know how that'll affect it but i don't mind. How would you go about changing it from 1333 mhz to 1600 mhz?

also, it says in the description that it's "SDRAM". I researched and SDRAM is supposedly different from DDR. Yet the link claims to be both DDR and SDRAM. I'm confused.

SDRAM is just an acronym for Synchronous Dynamic Random Access Memory which basically is the same as desktop DDR3 which actually stands for Double Data Rate ver 3 DRAM or SDRAM

With AMD most mobos have DOCP or EOCP overclocking profiles, you just enable and select 1600, some now have XMP (the Intel standard) with theat you enable it and select profile 1

That's (almost certainly) a different plug and play standard. Which is confusing, yes. That's what happens in the tech industry when marketing gets involved. =/

Tradesman explained the rest well.

I believe any motherboard that supports DDR3 will support kingston pnp ram. Ive used this ram on like $40 motherboards.

Got an answer from Kingston and a link on the sticks,

http://media.kingston.com/pdfs/HyperX_FURY_US.pdf

Looks like an interesting concept but appears to only come in 1333/9, 1600/10 and 1866/10 so are middling to slow, 1600/9 is basically the accepted entry level and in 1866 I look to CL/8 or 9 sticks, asked if they have any plans better performing sticks, Looked at the Egg and in 2x4GB there's about 11 sets at the slower 1866/10 (7 are Kingston, 3 are AData and 1 is Crucial - not really upper line stuff), there's anothe r 25 or so sets in 8 or 9

1866 CL10 is faster in every respect than 1600 CL9. 16.6% more bandwidth, 4.7% lower CAS latency (10.72ns vs 11.25ns).

Yes 1866/10 is slightly better than 1600/9, never said it wasn't, merely pointed out 1866/10 is the slow end of of 1866 DRAM almost all 1866 comes in CL8 (high end), CL9 (mid range) and CL10 (slow) for 1866. 1600/9 is the accepted entry level and w/ 1600 it's also available in faster CL7 and CL8 sets.....Not sure what you are trying to argue..... :)

As an example Newegg carries 81 models of DRAM at CL9 in 1866, 58 in 10, 1 in 11 and 2 in 13 (also 10 at CL 8 - so the far majority of sticks are are CL9 or better........1866 sticks came out before JEDEC had even set standards and their base is because 1333 and 1600 were higher thus they said higher....(Keep in mind JEDEC never planned for DDR3 to exceed 1600).....but no the the realworld standard is CL9

DDR3-1866 CL9 isn't even JEDEC-specified, so it's not standard. That doesn't mean it's not common.

The number of models available is not a reliable metric. If anything you need to look at sales volume. And not just retail memory, since most memory is not sold direct to customers, but to OEMs/system builders.

Since JEDEC didn't even release 'standards' till long after 1866 was on the market, it's the manufacturers who set the standards same with 2133, JEDEC is so far behind the curve there are no 'standards' for the higher rated sticks, keep in mind 1600 was the higherst JEDEC ever intended for DDR3 to go, and even then those were loose timings wise, they have completely failed to keep up with technological advances. The DRAM manufactures are setting the realworld standards

Oh and as a P.S. 1866 and above - most of it is indeed sold to consumers - not to OEMs or system builders (as in prebuilts) as few of them incorporate higher freq DRAM - most models stick to 1600 today

JEDEC lays out suggested standards yes, and in the case of 1866 and 2133 they actually issued 'standards' long after the products were all ready available (and had been), which leaves setting the standards to the manufacturers (and letting JEDEC play catch up - if they desire to try to, which apparently they have given up on as we don't have standards for todays high end DRAM and aren't likely to ever see any from JEDEC. There lack of impact on the DRAM market is also evidenced in the 'standards' they finally released, as you mention 1866 JEDEC standards call for 10-11-12-13 and yet there are basically almost no sticks at all out there in 11-13 (Know Mushkin has 2-3 sets or so), in CL10 - the BEST according to Jedec -you find it far outnumbered by CL9 and under.....in 2133 - again Jedec says 10-13, and yet again little to No 12-13 exist, here 10 and and 11 dominate, yet there are more CL9 sets available than CL10 (11 is the most and weakest) and again CL9 isn't even a 'standard'.

So in short since JEDEC didn't even issue 'standards' for 1866 or 2133 till long after the DRAM was on the market and already in heavy use, it's sort of hard to even give thought to them as being the 'standard' setters.....and againif they are who we should 'adhere' to for advice or recommendations then obviously higher freq DRAM shouldn't even be on the market...period, yet they are there and for high end rigs that really use DRAM they are great.

Additionally you will prob see the same happen with DDR4, the DDR Standard was initially issed Sep 2012 "JESD79-4", and it calls for DRAM from 1600-2133 (does anybody think that will last) and up to 16GB sticks, the manufactures are already working on higher freq DDR4 (again setting the true standards), just a couple months back, believe it was Hynix announced a 128GB module at 2133.

You can get the DDR4 standard at the JEDEC site as a member, or I believe that provide a signup for interested non-members

I have Patriot Intel Extreme Masters ram. It's advertised as 1866 10-11-10-30, pc 15000. If you look it up in BIOS, its listed as pc 12800, in CPU-z its listed in spd as pc 12800, 1600. In jadec, its listed as 1600, 9-9-9-24. It's only listed as 1866 under XMP profile (oc), 10-11-10-30, 1.5v. That's the highest profile available, even though this particular ram is capable of stable 2400 @ 10-11-10-30, 1.65v.

This is on a p8z77 board, with current BIOS upgrade. I would have to say that jadec is a little behind the times.
