The 2 changes we suggested are incredibly simple, and Mike`s picture explained it very clearly, and as far as the ram goes, all you have to do is enable XMP and choose the fastest speed that shows up when you enable XMP.
It`s a piece of Cheese Cake :)
OK, I know I'm coming in here late, and probably missed something but... Don't know what motherboard you guys are using but when you enable XMP, speed, timing, and voltage is automatically set. No need to change anything.... that's what XMP is for. It's a basic set it and forget it switch for RAM. Been that way with 3 Gigabyte boards - X58, Z87, Z170X, and an old Intel MB (Q6600 intel processor). Thus I'm curious why the OP would need to select a speed when it should be set automatically anyway?
BTW I set my RAM specs manually instead of using XMP, but that's another story as I don't want to confuse the OP.
Because there may be more then 1 profile on the ram, for example, mine has 2666 and 2800, that`s why I said to choose the fastest speed that shows up, if it only has 1 profile then he`s good to go.
His specs say he`s running it at 3200 so I`d assume all is well. :)
LOL, yeah I do
OK. but I just want to say this and move on... when you enable XMP, you're setting the module's specs as read. XMP get's it's info from the RAM so there's no need to set anything unless you plan on overriding it. And my board also has those pre-programmed "performance" profiles as well. Anyway the BIOS will tell you what RAM speed is, so you can double check there.
Oh, and nice job of helping him there
I never said anything about setting anything, you just enable XMP and choose the profile you want, that`s it, done. As I said my memory has 2 profiles.
I`m not talking about any Bios pre programmed performance profiles.
That's exactly my point - You shouldn't have to "choose the profile you want"! That's the purpose of XMP! The "module itself" tells the BIOS (through Serial Presence Detect (SPD)) what to set them to. A second set of high performance profiles - XMP (Extreme Module Profile), are also embedded here and read through the XMP module (in keeping things simple) which in turn basically overclocks the memory to higher specs read from that SPD ROM module when XMP Is enabled. With that, anything outside that profile is overriding the XMP info. Yes, you can still tweak the RAM, but the XMP profile says the RAM is guaranteed to run at this spec.
See this wikki article on Serial Presence Detect, then n scroll down and read Extreme Memory Profile (XMP). You can also see this post here
Those extra profiles you see on the motherboard are embedded into the motherboard's BIOS/UEFI firmware by the motherboard vendor, whereas the XMP profiles are embedded in the modules by the RAM vendor.
Mine has six. But as I said, these are customized profiles you could try, but they may not necessarily work or even match the specs programmed into the module's SPD ROM. And like you, I could choose anyone of those profiles, but as I said, would override the XMP profile... even if XMP is still enabled, which is shouldn't, but MB manufactures do all sorts of crazy BIOS tweaks so...
The nice thing with my MSI Z170A is, XMP has only one single profile, then there is "Memory Try It!" if you want to try other settings, but they are at least separate settings, and you are suppose to shut XMP off when using it.
You need to find what controller your RAM uses from a list(in my case, my Corsairs use Samsung, then select a profile.
I have an Asus Z270F Motherboard.
the Bios first page (UEFI BIOS Utilty - EZ Mode), has an X.M.P. button.
when you click it, the drop down menu gives 2 choices.
Disabled or Profile #1.
it was set at Disabled by default.
I changed it to Profile #1.
saving and resetting, then changed my Corsair LPX to run at 3200 MHz (from 2133 MHz).
it was indeed a piece of Cheese Cake. lol
the only other change I have made is in the Advanced Mode, on the Ai Tweaker page, under CPU Core Ratio (which is set to Auto), the next line says:
1 - Core Ratio Limit
I changed that setting to 45. (it was Auto by default).
I do notice on that Ai Tweaker page that there are XMP settings. they must have automatically changed when I changed to Profile #1 on the first page (EZ Mode).
as for my question about increasing my RAM from 16 GB to 32 GB:
would anyone please tell me their thoughts about it?
it won't be a matched set. so, should I forget it?
I'm not going to take the existing 16 GB out, and buy 32 new GB RAM. not today anyway.
thank you for any thoughts.
The amount of RAM you need depends on the use of the machines.
16GB is optimal for gaming PC's, strictly overclocking PC's, or heavy multitasking.
32GB is optimal for workstation PC's, video editing, music production, or a few virtual machines.
Over 32GB if you use many virtual machines at the same time.
If in doubt, add more RAM.
