@carking - Thanks for new pic, I see you also can't see the "live values" above Memory Reference clock either (there should be entire list, just to show current values)
For now, see if this changes things, if not I see why it's grayed by default >> A setting on the OC page, that's hidden from you right now, I'm making visible now too please confirm >> (memory profile setting) if = 0x1 then all = grayed out at memory timings, but default is 0x0 so I don't see why it's grayed
We will get it though! - http://s000.tinyupload.com/index.php?fil...870278561515884

@Lost_N_BIOS
THX, i can always see the values in bios, just did not catch it in my pics.

I can finally access the value now. see the pics
But after my attempts, no matter how I change and save, it can't be applied into Windows, so setting not work. Sometimes memory value setting will return to the default value after I save bios setting and reboot .
Maybe in the OC setting the mem profile is set to "default profile"? but there is no other section can be select in the men profile setting, you can check in the pics below.

Yes, I meant in OC, the memory profile setting is what's tied to why it's grayed out or not initially. Nothing to worry about for that now though, leave on default, or you can try XMP if your memory has XMP.
What settings are you changing and they aren't sticking? What are you checking with in windows, show me an image what you set in BIOS then what you see in windows.

Hi @Lost_N_BIOS
Changing the timing setting not work (CL/ RCD/RP/RAS )
use CPU-Z to check how it work.

Thanks, I wanted to confirm how you were checking in windows, some confuse stock timings/SPD/XMP for actual current, plus I wanted to make sure you weren't maybe setting impossible settings so it was failing to use them.
All you set is reasonable and should be working, I think the issue is "Default Profile" where you can choose default or XMP, there should also be a "Custom" which isn't in this BIOS.
I will see if I can get "Default" changed to custom instead. If I can't then this isn't going to work

Here is test, I changed memory profile from 0 to 1, but it remained "Default Profile" where I expected it to change to "Custom" So this may not help, and this may also again gray it all out?
I'll keep digging - http://s000.tinyupload.com/index.php?fil...152157952421555

Also, please link me to this exact product at Zotac's site, I can't find it, I only find "EN1060K PLUS" or "MAGNUS EN1060 PLUS i3" and "MAGNUS EN1060K"
I wanted to see what exact chipset it's using. And, since you have this system in hand, can you look at the motherboard, then compare with all other regular desktop same chipset boards at Zotac's site and link me to any that look to be exactly the same or nearly the same visually
With that, if you can find exact same board, we can put in it's setup/AMITSE/AMITSE-SetupData and see if you get a better BIOS or not. This has some risk though, so before we do this make sure you get a complete and valid BIOS dump with your programmer or with FPT if you've already unlocked the FD

Hi @Lost_N_BIOS
Good news, it work. I finally lowered the memory timing.
Although their is only the default profile setting can select,no Custom profile setting show up, but after change some timing value, it work in the Windows. Check the pics.

About the zotac bios, all EN1060/1070(K or something else) series use the same bios(same motherboard), it mean EN1060K PLUS/MAGNUS EN1060 PLUS i3/MAGNUS EN1060K use the same bios, you can download it and check the bios file MD5, all same.

Thank you for your patience and effort these two days. I even wanted to give up before. It’s really a waste of our time.

@carking - yes, I assumed no "Custom" would show up, or it would have on my end in the setup IFR after modifications, but it remained "Default"
Thanks for the BIOS info, so all have same chipset then too correct? If you want we can try what I mentioned with the normal desktop BIOS for a similar looking board, but you'll have to look at the board images and pick the one that best matches your current board.

So, on the memory timing, you couldn't change to main timings to 12 before this latest BIOS I sent? Or, did you only try 17 as shown in those images? If you only tried 17 and didn't try lower, that BIOS may be OK too, but only 15 is max or something like that, but you could lower possibly too?

If you change "Memory Reference Clock" you can reach different speeds x your set memory multiplier. And if you enable the Qclk Odd Ratio you can usually get different multipliers as well.

You're welcome! I don't like to give up, as you noticed, with enough methods tried you can usually find the correct working way to reach your goals
