Aorus x370 gaming 5 ram issue

bigbearballew · May 11, 2017

I have an aorus x370 gaming 5 motherboard (bios f5) with 16 gigs Corsair vengence lpx 3200mhz ram. The ram will only operate at 2133mhz and anytime I try to up it in the xmp profile to any setting higher than that the system will not boot. Does anyone have any idea how this might be solved?

Welcome to AMD ram issues. This is a known problem for AMD Ryzen CPUs.. The best thing you can do is hope for a BIOS update for better compatibility or buy some G.Skill FlareX ram that is known to work. You probably will never get 3200 out of that ram kit. But can always hope

Here is a long thread about the same issue. http://www.tomshardware.com/answers/id-3394915/ryzen-ram-32gb-3200mhz.html

well thats a real bummer, i picked that kit based on the fact that it was supposed to be certified for ryzen compatibility based on this article http://www.legitreviews.com/ddr4-memory-scaling-amd-am4-platform-best-memory-kit-amd-ryzen-cpus_192259 . Kinda makes me a bit irritated, im sure everything will smooth out eventually

I believe the newest BIOS just got released for that board from Gigabyte. I would flash to that, and keep xmp enabled and see what you get.

Did you get 2 x 8gb sticks or 1x16gb ? I believe 2x8gb has the best compatability for top speeds.

I have the 2x 8 gig sticks. And yeah I'll try to see if that does anything. It's really annoying. It feels like the computer is slower because of it.

bigbearballew :

You should be getting at least 2666mhz, its odd you are getting such a low speed. I think the BIOS flash is your answer.
Most people are getting 2998hz (3000hz) with that kit and board. 3200 will be if you are lucky. You might have to manually adjust to that. But flash to the latest BIOS via USB, and enable xmp and see what you get.

bigbearballew · May 15, 2017

Yeah I'll be doing that. I have literally no experience overclock ram and no matter how much I read on it I still feel confused lol. Just something I'm having a difficult time grasping

bigbearballew :

Hopefully with latest bios, xmp does the work for you, and you won't have to worry about it. The performance difference between 3000 and 3200 isn't really all that much. The difference between 2133 and 3000 is def noticeable.

Actually 2400@CL10 on the performance index is faster than 3000@CL14. If you cannot go higher, than just tighten up the timings and call it a day.

Like I said, I have no idea how to OC ram, I'll have to figure it tonight.

iamacow · May 15, 2017

You don't really have to "overclock" the ram like the CPU these days. There is a whole tab dedicated to memory in the bios. But really, simply pick the speed you want and that's it. The system takes care of the rest. You can mess with the sub timmings and that is stuff you gotta do a lot a reading about and trail and error.

bigbearballew · May 15, 2017

Oh dang I didn't know it was that simple...

iamacow · May 16, 2017

as long as your don't mess with voltages the worst you can do is get failed boot. So even if you don't know exactly what you are doing, it won't cause any harm.

Maybe that was correct before Ryzen, but the CPU and bridge is highly connected to Ram Speed, and the timings don't actually matter that much. https://www.eteknix.com/memory-speed-large-impact-ryzen-performance/ for reference. The general consensus to get the highest Ryzen performance is to push the Ram speed as fast as you can, and then tighten timings. Regardless he should be getting 2666 as that is supported by every board especially an x370 board. 99% The BIOS is his problem.

Techpowerup has link for beta BIOS just out for AX370-Gaming 5 : https://www.techpowerup.com/233345/tpus-ryzen-bios-digest-issue-4

Maybe that can help you.

bigbearballew · May 16, 2017

I just finished tinkering around with everything. I loaded my optimized defaults and pushed the multiplier up in the xmp tab. I've got the ram at 2933 mhz for now. The computer seems to be more responsive overall. Thanks everyone for your help!

eyupo92 · May 19, 2017

Look at this clip :'AMD confirmed that its AGESA update for May improves DDR4 memory compatibility, although it also stressed on the need for motherboard manufacturers to improve their board designs in the future, with more PCB layers and better copper traces between the DIMM slots and the SoC socket. '

So, there is a hardware related issue as well.

eyupo92 · May 20, 2017

Actually the original article shows a much worser situation.

I hated the tone used by AMD staff here.

They blame memory manufacturers not following JEDEC ( Intel complained about this 8 years ago ), programming wrong microcode into their overclock RAM, motherboard manufacturers using less copper and less layers on motherboards and finally claiming RAM above 2400 MHz are a specialty item etc etc.

And they are doing this after necessitating a RAM with above 2400 MHz for their CPU to perform as good as competition does without OC RAM. Tap dancing on their stupid hardware design failure and blaming the companies who created products that work even under these limitations. Great job.

Any further comment on this would let me banned from forum forever.
