Massive Set of Changes to DDR4 Guide

[Arshia1381]

Made a crap tonne of changes its currently unfinished but I thought I'd temporarily post what I've done so far, adding/changing more. Most if not all info that isnt sourced has been checked with OC discord.

Changes: Made definitive note about Spektek being micron Added Rank/SOC volt relationship Added ICs to scaling and tRFC tables Reworked entire IC tier list Changed frequency table format and info Added info about binning and binning tiers Added and revised info about how voltages work Slowly reworking "MHz" to just DDR4-xxxx to resolve potential confusion and to be technically correct Added info about Command rate Added small comments all around

Feedback on all changes would be appreciated from anyone with any technical know-how. Will be further revising these changes tomorrow.

Great work mate.

I noticed one part which probably raised more questions than it answered. There's a mention of ryzen SOC voltage and that it should not be left on auto. This left me wondering, is this because auto might run it dangerously high? Unstably low? Scale it with load thus potentially reducing stability? Change it depending on other variables? ...You get the idea...

Obviously, this might be complex to cover off the whole range of possibilities, but perhaps if you're not able to specifically state why it shouldn't be on auto, then at least give something to look out for that might be a danger sign of it being on auto (high voltages etc)? I don't know you seem to have a good grasp on what needs to be said, I think you get my drift.

Mainly cause it's likely gonna fluctuate a lot. On some mobos, this is more often than not gonna be unstable levels of low. Also especially helpful with running dual rank or 4 dimm setups that need higher voltage. I don't actually have a source as I'm not the original author of that line, however I am of the belief that setting SOC voltage manually is a fundamentally good idea when OCing.

Auto sets 1.1V here...... It's literally the same as setting it to 1.1V. That is not to say that EVERY motherboard acts like mine, of course, but it demonstrates why this advice given as a general truth, isn't generally true, which is why it should change.

The years have taught me why "if it ain't broke don't fix it" is a thing. We all have our different methods :) But the issue here isn't whether or not it should be done - the issue is that the guide leaves the reader 'knowing' there is a problem (edit: actually, they don't, but they think there is a problem because they've been presented with a solution!) but not what to look for to find the problem or fix it. I've a perfectly stable OC and plenty of experience but that line was enough to make me doubt it all and sent me searching through my BIOS for an hour trying to find out what was wrong with auto. The answer was "absolutely nothing". Now, had the line in the guide said something like "under auto settings, some BIOS will not set sufficient voltage or will dynamically scale voltage with load, reducing stability - accordingly it may be necessary to manually set the voltage if the system is unstable" then I'd have actually understood it as what you intended, and known that my auto setting was fine.... and obviously if I were one of the unlucky ones with low or fluctuating voltages, I'd have looked for it, seen it, and fixed the voltage as suggested.

So, do we have any real info about auto SoC voltage yet?

I'll take the shocked silence as a no then.
