Hi,
A customer just sent me the parts for two machines - all purchased at OC :)

I don't want to overclock anything
(yet)

The relevant bits:

i7 8086K S-spec @4000MHz
Gigabyte Aorus Ultimate Gaming z370
Corsair Vengeance DOMINATOR Platinum 2x16GB @3466

I built the first machine last night and have not slept since ;)

My only problem -

The RAM will not run anywhere but 2133. I set it up, go through the whole "The system has experienced a boot failure ... ", set it up and then boot override so it goes straight to the OS (which, I mistakenly believed 'forced' my custom settings but, it seems, just 'restores' the basic speed before booting) where AIDA tells me NO! - 2133!!!! Stupid human.

I have followed guides and searched forums but this is the first place for me to display my failure/ignorance.

Yes. I reset to defaults. Every time I failed.
Yes. I cleared the CMOS. Regularly.
Yes I tried the other pair of slots.
Yes I tried the other pair of sticks.
Yes. I tried the other pair of sticks in both pairs of slots.
Permutate any 2 from the above and I have tried it :)

Thanks in advance.
 
Yeah, sorry, I should have said. I tried everything in the bios.

With/without the XMP profile the board 'finds' (which is exactly what the memory says on its very fancy tin - 3466MHz @ 16-16-18-36) - same old same old. Manually set every (documented) parameter also. Followed Gigabyte's own overclocking doc for these boards so as to disable any 'problem' settings in frequency and voltage areas.

Then reset to defaults again lol. I have been banging my head for 19 hours straight now.

I am over 60 and built my first machine back in the Eighties - an 8086 funnily enough. Had a jumper block 20x20 pairs and every jumper was the wrong way round. No help back then. Took me 3 days to get it running. Then introducing a 5Mb hard drive to it sent me down a path I have traveled since ...

How many sticks are you running 2 or 4?

I take it 4 but you still can't get XMP to work with 2?

2x16

Yeah - turned on, set defaults, save and reboot, enable XMP, boot, fail, install OS, set defaults, manual setup of RAM. Fail, lol. Fiddle with hardware, set defaults, fiddle with bios - rinse/repeat

I don't know whether to be annoyed that this m/board will not allow at least one boot with my settings after warning me - eg: enter bios, check parameters haven't changed yet, boot override - very quick post and boot but ... it wipes my setup of the memory freq/voltage/timings but leaves anything else I alter (so far fan timings and gigabyte's own overclock settings.

Might be because it's 16gb sticks rather than 8gb.

Have you tried with 1 stick and have you tried a lower speed like 3000mhz?

Failing that it might be worth memtesting the ram to ensure it's not faulty..

Thanks. I did try one stick at first just to see what was happening. I have tried 2200MHz and up just for symmetry 8) (usually in 200MHz increments)

XMP, 3200hz speed and bump up ram voltage and boot voltage to 1.45v - leave timings

I might try that now thanks

Some positive points you made, but from what i have seen with my Gaming 7 F7 bios. 4 dim 4000 kits are limited @3600 CL18 and even those with XMP enabled does not work right.
benchmarks are crippled speeds are more than half crippled its like they broke something...

Yeah - just tried the voltages (I am not comfortable but in the interest of sanity) and 'Memory Read' test in aida (latest)

@3066MHz - 13068

@2133MHz - 32586

identical timings - bios changes: xmp off and back to stock voltages = double the bench

annoying
 
+it was set at 1.350V and turning it down made no difference so ... 1.470 at stock timings it is. XMP set it at 1.2V though - making me guess that in another board this RAM would act less fussily as the manufacturer says 1.35V.

I am handing off the machines to the customer tomorrow.

Even @3066 (now the board is happy with that because V) it comes up in AIDA 1st in latency sub 55ns and above everything but a Rizen on a X*** chipset (by a 1.5% hair I could split I know) and quad and octal RAM lab rats in memory read/write, fpu and photo worxx. Which suits because flattening in PhotoShop and fast hard drive (which he has) are key.

Such a shame Gigabyte don't reply to queries, do much about complaints and muffle the bandwidth (on these boards at least - I usually recommend Asus but this guy was adamant) as these boards are nice in most other respects. Best thing I found out about in this build were the R6 cases from Fractal Design - great airflow, good sound insulation, good options for twin liquid cooling, nice rack 8)
