Hello,
 
I have a Micro2 and have the latest Bios installed (v2.02) and within the notes section relating to that version of Bios, it reports a memory ratio increase of 3400/3600/3800. Despite this, the maximum speed of installed memory is still only 3200Mhz on this Micro2 motherboard, can anyone explain this please?
 
Thanks in advance.
 
 

No XMP is enabled.
XMP 2 is not available in Bios, only XMP 1.
The Corsair memory is capable of XMP 2.
The memory speed is currently set to the maximum available speed in Bios which is 3200 but the installed memory can function at 3600MHz right out of the box.
 
 

Appreciated, but that doesn't answer my question relating to EVGA announcing a memory speed increase with Bios V2.02 when infact this is not an option that is available in the Bios settings, only 3200.

Just to clarify, when you set the XMP profile in the BIOS for the memory, is it running at 3600 or 3200mhz?

I only have the XMP 1 option available in Bios.
When XMP 1 is set, the memory runs at 2134MHz. This is why I opted for a manual selection of the maximum of 3200MHz because it is indeed a lot faster than the XMP 1 setting.
The memory does run at the 3200MHz when set to 3200 in Bios with no problem but it can go at it's full 3600MHz with no overclocking. EVGA say the ratio has been increased to cater for 3400/3600/3800 modules in Bios 2.02 but this is simply not true on this motherboard. 

Okay..something isn't right here. It is the XMP profile that is supposed to set the memory to 3600. Using CPU-Z, what is the XMP profile listed for the memory?

XMP (Extreme Memory Profile) is basically a non-JEDEC approved SPD table for your ram that is programmed into the sticks themselves.

I'm not sure, what he's got going on there. On my FTW board I can set up to 4000mhz memory speed, separate from using the XMP profile. If I remember correctly regarding the updated BIOS, that was adding in memory compatibility where you could run memory faster than spec without over clocking the base clock from 100mhz. Earlier BIOS would raise the clock to 125mhz on higher speed memory.

Here are two screen shots regarding CPUz.
 
In photo 1, the memory speed is set to the maximum available of 3200Mhz (Manual)
in Photo 2, the memory is set to the only XPM choice available which is XMP1.
 
My Corsair Vengeance LPX DDR4 3600MHz (CMK32GX4M4B3600C18) is capable of XMP2 but not on this MICRO2 board it seems.

They appear to be identical - very strange
 
 

Manually on my X99 Classified with BIOS 2.03 I see a max of 3200MHz, which is what I have my Corsair Vengeance LPX 2800MHz rated RAM running at.

I thought I would update this post.
 
I emailed EVGA's customer support. Waited for a few days and finally received a response from Matthew Decker.
 
Hello,

all DDR4 runs at 2133 mhz. When you see DDR4 advertised at 3200 mhz or 4200 mhz that means that the memory modules were overclocked to that speed and tested for stability. 

The Micro 2 has no cap on memory speed. However, most DDR4 speeds above 2666 mhz will require a CPU overclock due to the memory controller limitations of the CPU (this is on ALL x99 motherboards)

Memory speeds above 2800 mhz are usually obtained through BCLK (STRAP) overclocking. If you are unfamiliar with this I would suggest looking at some overclocking guides that use BCLK ratio overclocks online.

Please let us know if there is anything else we can assist you with in regard to your EVGA products by contacting support at support@evga.com or 888-881-3842 for further assistance.
 
This bloke clearly did not even bother to read my email properly!
I replied to his email:
 

Dear Matthew,
 
Thank you for your reply and I understand what you are saying but unfortunately my question has not been answered.
 
Within my Micro2 bios, under 'Memory' I have the option of changing the memory controller from Auto to XMP1 or to Manual.
When I select 'Manual' I can then adjust the speed at which my memory functions. The maximum speed setting appears to be 3200MHz.
The latest bios for this Micro2 board is v2.02 and within the notes that accompany the file on your website report that the memory ratio has been increased (3400/3600/3800) (Preset memory values?) but these are not available in the memory speed settings I mentioned earlier, why is this?
Shouldn't I be able to now set my memory speed to 3600 or 3800 as the details say I can?
I have certainly updated my bios correctly, so I am a little confused.
My Corsair Vengeance LPX memory is rated at 3600Mhz right out of the box.
One further question I have is that I only have XMP1 available in bios, I am unable to select XMP2 even though my memory is rated with XMP2, can you explain this please?
When I set the XMP1 my memory only works at 2134Mhz.

I waited 7 days for a reply and received nothing, zilch, zero.
So I emailed them again, waited several more days and finally received this email from Ray Hedrick:

Hello,

The update will help with support of some kits to run at those higher speeds. That said the X99 platform tends to be less flexible than the Z170 and Z270 chipsets when it comes to speeds of 3200 Mhz or higher. It is possible that the RAM will not be able to operate at higher than 3000 Mhz despite the BIOS update.

Regards,E
EVGA

This is a joke, right?
What on earth is that supposed to answer? 
Ray obviously could not be bothered to read the email and has just copied and pasted complete rubbish that is no way even close to answering a single point.
I am seriously annoyed with EVGA, they can't be bothered or perhaps are not suitably qualified to answer their customers questions but the are happy to accept the many thousands of pounds that I have been spending with them.
Perhaps I will return to ASUS as they are a very helpful support team!

Awesome work EVGA

There's some confusion here also as there are apparently some differences between processor models and what is available. I, can set any memory speed from 800mhz all the way to 4000mhz and not affect the BCLK at all. The newer Z270 does list support for some higher memory speeds, but I think that is more a function of higher speed being available versus an actual change in processor capability. With your memory, there is only a single XMP profile according to the Corsair support page for the memory.
 

So...
 
I emailed EVGA once again to ask the same questions because at some point they might actually give me a straight answer. I waited another 7 days or so and finally received an email from Markus Kaesbauer.
 
 
"Hi,

thanks for your detailed request – so we were in contact within our Engineer Department “New BIOS allows overclockers to be able to try higher memory ratio which above 3200. But that is not guaranteed that they can work on those ratios. Our X99 Micro 2 memory spec. is 3200+ and we have provide our AVL list on our website. Any ratio which above 3200 is out of our spec. and will not be guaranteed” – for the X99 platform, the max workable should be roughly on 3200.

Please let us know if we can further assist,

Regards"
 
I laughed and threw in the towel. They are clearly unable to read questions correctly let alone answer anything you ask them.
 
Today I removed the Haswell 5960x and replaced it with a Broadwell 6900k.
I have kept the exact same hardware, only swapped out the CPU.
Entered Bios and checked the maximum RAM speed available and TaaDaaaa  4000MHz.
 
 
 
All EVGA needed to say in reply to my simple question was:
 
The maximum memory speed available in the manual configuration is 3200MHz on Haswell and 4000MHz on Broadwell.
 
One sentence, but they refused to answer anything directly. EVGA customer support is seriously way behind other brands and that is a real shame because their products are exceptional.
 
I thought other people might like definitive proof that the settings that EVGA say are available within their motherboard bios are not actually the same for all CPU architectures. In this case, Haswell verses Broadwell.
It has honestly been horrendous dealing with their customer support staff and it'll be the last time I purchase one of their motherboards, that's for sure.
 
 
 
 
 

I have to chime in here

From My Hands on experience with the "Micro 2" MB
I can tell you with out a doubt that when I ran My Gskill Z 3200 at 3200mhz 
i could only get that frequency  on XMP2 and that would only work if I set my CPU clock speeds to run at 3.8 over clocked (On a 5820K)
EVGA Jacob says that that's not the case for Other X99 CPU's only the 5820K
 
Now to make things even more confusing
 
I bought some Corsair Vengeance LED 3200 and could only run XMP1 and could never get over 2800 stable no mater what I did to my CPU
 
 
I am 100% sure about 2 things on the Micro 2 MB
 
#1
the higher clocked Ram  May or May-not be determined  by the CPU frequency When running Different CPU's 5820K, 5930K, 5060X
and what Clocked speeds they are at
 
#2
The Micro 2 MB does not Clock as good as the Larger boards like the FTW and the Classy X99's
Not sure if that has to do with the lack of the extra 6/8 pin power connector found on the Classy and FTW MB's
But in my experience with both these boards...........something is different in the way the Micro 2 and Classy MB's handle CPU frequency
and it's correspondence to Ram Frequency  


Wish I could be more help
