Gigabyte Z270 Gaming 7 Bios not keeping settings

[jossrik]

Sorry, gonna be a long post.

I got a rig here, it's got a two week old Gigabyte Aorus Z270 Gaming 7, 32Gb RAM 3200CL15 in a 2x16gb config, 6700k delidded under custom water, overclocked to 4.6, RX 470, EVGA 1300w G2, Samsung 960 Evo 500Gb. Stock with just the CPU overclocked ran for two weeks flawless. Games, stress tests (under 70c @ all times CPU). Decided to see if I could squeeze a little out of the memory and that's where I sit confused now. Been playing with it for four hours. Restarted into bios, upped the memory from 3200 to 3400 (skipped the 3333 or whatnot setting inbetween) and since then I can't get it to boot with anything but 2133 memory speeds, although, I have gotten it to reset the timings.

First it would only boot with 17-18-18 timings, that wasn't me, the board decided that. This is at 2133. So, flipped XMP off rebooted, 2133 17-18-18, ok, reboot, flipped XMP back on, 2133, 17-18-18, WTF, rebooted, manually went into settings, set it to 3200, left secondary timings alone, reboot, 2133-17-18-18, rebooted. Failsafe into windows, my CPU changes are still , 4.6 Going strong. Checked my bios, update that helps fast XMP, ok, maybe there's some good in there, updated the bios, that goes fine, no problems. Bios set up my CPU, set memory to XMP, nothing else, reboot, 2133 15-15-15 (The 2ndary it's rated at), the memory is about a year old, but it's G.Skill Trident 3200 15 XMP. For some reason I can't get any changes I make in the bios to take. I know I'm missing something, but for the life of me I can't find it.

The F41 beta bios is supposed to help with that, though still in beta and have seen some similar complaints looking on Amazon after reading your post. Another complaint for that board has been re sound. All things considered it's disappointing/possible deal breaker, especially if it's something you were looking forward to being able to do with the board, (and with the reviews and Gigabyte advertising it can support 1000 types of ram and an xmp profile up to a 4133mhz). Maybe it's worth trying different ram, though like you said, your ram isnt old and is also a ubiquitous brand. Not knocking gigabyte here, just disappointing considering how nice that board looks, and is supposed to be.

Ya. I'm pretty disappointed, always been big on Asus, this is my first Gigabyte board after being able to buy whatever I want and for the price it's pretty bland. It's got the basic stuff, but any bling is seriously missing with the exception of RGB LEDs. Put the RAM into the other two slots and *without changing the bios* it's reporting at 3200 15-15-15. I can't help feeling this is a bios problem though not a RAM slot problem, they run fine no errors mistakes, just not at the rated, and the bios changes wouldn't take. Now I'm scared to try overclocking the RAM for fear of messing up the other two slots, then again, I didn't try the second bios, seemed like something you wouldn't need cause it's pretty hard to mess up the first without having a good idea what you're doing, you can always clear CMOS. From the googling I been doing it seems the z170/270 boards are coming through with poor QC. Stuff is selling that a few years ago wouldn't have gotten out, but it seems to be pretty random the issues. There's one on the Gigabyte forum post with the same exact problem as me but on a X99 (I think, it's kinda late and I just took my meds), no responses to his post, and he's running 4x16Gb, so maybe can't even try alternate slots(I don't know X99 boards very well)
