TeamGroup 8pack 4000 kits : Gigabyte Z370 F8 bios Breaks Them

ViRuS2k · 27 Jul 2018 at 23:10

Just a word of warning gigabyte recently released official F7 bios for the gaming 7 motherboards.
previous to this bios F6 ran the memory perfectly @4000mhz with XMP enabled albet they ran at 19.18.18.38 but worked @4000mhz 8 pack said that was a motherboard bug and they where infact running @ 18.18.18.38 as advertised with xmp enabled.

but now that im on F7 the max the memory can get to is 3600mhz with XMP enabled
with 18.18.18.38 being correctly stated in windows now.

but as you can see F7 breaks the speed and F6 breaks the timings.
with 8pack saying on f6 that the timings where a bios bug but this is clearly not the case as the bug has been fixed with f8 but running much slower.

hence, do your self a favour and stick with F6 bios or run F6 bios with the latest modules and dont jump to F7

I would be interested to know from the gigabyte rep and 8pack or team group rep just what the problem is with this memory and this board.

EDIT: can a mod please change topic question its not F8 its F7 i ment to type lol

I wonder where the gigabyte rep or team group rep or 8 pack are to investigate why the 4000 mhz kits do not operate at XMP under the latest released F7 bios for the gaming 7 Z370 motherboards. i mean the memory does not even run properly under XMP with F7 getting very very low bandwith figures even at reduces 3600 mhz speeds from F7`s XMP mode.
when the speed was at 4000 on the previous bios albet running at 19.18.18 instead of 18.18.18

please advice is needed or help to get this memory running back at 4000 rated XMP.

Why did you update??? Role back!!! Whats the new Bios offering above last one?? The last one was working fine just role back.... I will ask the Gigabyte team about the rest because I got them to fix it in the first place and tested so not sure whats going on!!

I have rolled back m8.... 4000mhz again

(just to let you know though gigabyte have blocked F7 firmware from rolling back to F6 i had to go through hex editing the F6 bios to allow flashback) meny people that have the same memory if they update they may be locked in if they dont know how to revert).

Reason why i updated was cause the bios fixed boot up issues and new cpu microcode for upcoming cpu to be released.

i have no idea though how they managed to completely break the 8 pack 4000mhz memory kit as the speeds are abysmal with f7....
hope you can find out exactly what or why they did this or if its a timing issue that needs edited in let me know. cheers.

I dont have time right now to check this out but will follow up when I can I messaged Gigabyte about it already.... see exactly what they say..

ViRuS2k · 2 Aug 2018 at 16:27

Hope you can do something about it mate, been pluttering about with the timings and all sorts of stuff to try and get 4000mhz, i managed to do it by changing 18.18.18. to 19.18.18 but still very unstable
i tried xmp and it runs the memory at 3600mhz @18.18.18. but its very unstable also with both settings bandwith is vastly reduced in speed like the memory is in limp mode with any combination lol

wish they just left the memory for this kit alone at what it was optimized for with F6 bios as it was pretty much always stable at xmp albet with 19.18.18 @4000mhz but it was completely stable and ran at full speed.

hope they can tweak this back to how they had it with the timings fixed cause i know the board can do it, its just a setting somewhere that i just cant think of to change....

cheers for the help, hell if gigabyte as slow to get back to you is there any way you can chuck a gaming 7 with 8700k on a test bench and update firmware to F7 and try to tweak the 4000memory 4x8gb set with your tweaking magic and i can at least try some settings lol im sure you would be better...

Have you had any news yet 8pack m8 ?

Silent_Scone · 6 Aug 2018 at 12:47

Pitty but some changes to auto ruling on the memory break it for some and fix it for others. Best answer is what Ian's already said for now and just stick with a build that works for you.

You might even be able to dial it out manually...

Well thats the plan if they cant fix there mess up then i asked if 8 pack could throw the stuff on a test bench and see how far he can tweak the 4x sticks on gaming 7 board with F7 bios.
and see if he can dile the speeds back in and get proper performance. @4000

im going to have another mess about at the weekend and see if i can dial them in manually myself, but im no way a expert at memory tuning so hence why i asked 8pack as he tweaked my last set of corsair memory on my z79 platform of my previous system and it was awesome.
hoping he can do the same.

8Pack ? Any news yet, m8...

No

Getting to the point and very blunt i see,
Well you would think they would be quicker eh.
I guess us customers to GIGABYTE mean very little to them.. even though we buy there hardware, and i would have thought being you that you would have got a even quicker response being that its your sponsored memory kits that are on there QVL list of approved memory on the board gigabyte gaming 7 that are XMP Approved that are in question..
But anyway, i will try to figure something to fix this issue probably change boards to Asus Apex or change ram to something different... that has Samsung B - Die

what? your ram is already b-die lol there is no die in the world that can do 4000 with that latency and voltage. Problem is the board, just get something decent like Asus Apex or ITX boards with 2 dimms

Gigs bios team have been pretty poor in the past, I avoid their boards now.

ViRuS2k · 11 Aug 2018 at 17:19

Been tweaking today, and managed to get some good results from the F7 bios but i had to manually dial them in...
as XMP just does not work anymore.

8pack or anything if you see the timings if there is anything i can improve on or change let me know thanks.

prjwebb · 12 Aug 2018 at 13:00

Those results don't look great for 4000. I'm running mine at 3600c15 and have 54000 on the read and pretty similar write and copy and nearly 10ns less latency.

Can you popup a screenshot of your timings using asrock timing configuration for me.
though you must be using 4x8 sticks as i think i have something to loose or to tight thats reducing bandwith somewhat, i need to figure it out and yeah latecy is high im sure thats cause of the RTL/IOLs those look high also not sure how to reduce them though.

Will post later. I'm only on 2x8gb though.

problem is OP has 4 sticks - records are done only using 2 sticks . Asking IMC to hold out 4000hz with 4 sticks is still an ask .

guessing you've tried XMP with just 2 sticks to see if it works then then 4 sticks to see if thats causing the issue with the board ? If problem is with 2 sticks as well then fair enough- bios update has caused issue and should have worked fine .

is uncore at 5ghz ? 5.2ghz on the core, nice!

Yeah issue with XMP is with all 4 sticks aswell as 2 sticks.
gigabyte fumbled the settings up on the sticks to begin with so that they would appear to work at 4000mhz but where using 19.18.18.38 instead of 18.18.18.38 and that made XMP work on F6 bios.
now that im on F7 they fixed the sticks XMP setting so that XMP enables 18.18.18 now and thats correct but i dont think the board can handle these sticks @4000mhz at there XMP setting when properly fixed. they require more voltage over XMP with F7 ....

and yeah 4x sticks are easy to get 4000mhz but 4000mhz on 4x8 sticks are more taxing.

i still beleave there are issues though with the board in general i dont this these issues im getting are ram issues at all, i just think the board is pretty crap (gaming 7) with ram in general compared to boards like the APEX. i should have gone for a APEX board i might just ditch this and stick to asus boards in future as gigabyte are just not there when it comes to memory compatibility OCing.

ALSO you would actually think a gigabyte rep would have come in here by now to rectify some information or help there customers or even get back to 8pack so he could give some answers but i guess one customer to them means nothing.
