Memory speed wrong

Hi all,
Ok I have a Gigabyte B450 Aorus pro motherboard, I purchased 2 sticks of 8GB DDR4 Corsair Vengeance LPX 3200MHz,
CMK16GX4M2B3200C16, After installing I went into the bios, under MIT I set the profile to 1 and 3200 was read and I thought great the motherboard sees the new ram and its speed. I saved and exit, after 2 unsuccessful posts on the 3rd post windows booted, in task manager, cpuid and easytune they all read the ram speed as 2133mhz.
I manually set the speed in easytune , a reboot was needed, and again 2 posts and on the 3rd one windows booted.
Contacted Gigabyte, they suggested I flash the bios to version F40, and clear the cmos which I did, back into bios , set to profile 1 and the same thing, everything I try windows boots to a ram speed of 2133mhz.

So has anyone had the same problems and a fix for me, because so far Gigabyte dont, any help I'd be grateful.

Thanks
Brio

I am running on the 470 version though I have some experience with the UD3 450 Board (IIRC) their ultra cheapo one. The BIOS revisions are one part of the equation. I have that memory, FYI and it was a bastard to get it stable at 3200 Mhz on at least two B series boards (a Tomahawk B350 and the Gigabyte one). Initially, the only way I got it stable at 3200 Mhz back in the early Ryzen days was to crank the voltage to 1.5 on the RAM. It can and will take that voltage level in stride, that memory is durable. You might attempt kicking the voltage up. Make sure you're not running your timings too tight on that memory. If I recall the memory timings on that stuff were looser than my occasional side action (and that's pretty damn bad).

Now, I think it's Hynix memory... I forget. However, as with all these Boards and Memory there's the silicon lottery to deal with. Not every stick of RAM or motherboard is gonna allow you to get the ram to the rated speeds. That memory wasn't on any of my qualified lists for my (Tomahawk, never checked the Gigabyte) MOBOs so, there's that. Now that's more of a guideline than a solid "it's not gonna work". I am confident you can get it rolling at the very least to 2933. That might end up being your ceiling, and that's not all that bad. I wouldn't be happy (and god knows I wasn't when I had to drop my speed from 3200 to 2933 for stability reasons) but it's just what you have to work with. If you want better chances at faster frequencies you need to buy faster rated memory that is "guaranteed" to run faster. Or you buy memory that is on the tested list of the MOBO.

Just my jar of change for ya

Thanks for your reply, question, did you set the voltage in the bios because ive played around with the bios and all the ram voltage settings are greyed out and i cant double click on them even when i set it to manual, so can't set the voltage in the bios?

I did configure the voltage settings in the BIOS. I am guessing you can't accept the XMP settings or whatever AMD is calling them in their BIOS these days. Going to have to go hardcore manual, and adjust the settings yourself. If I am not mistaken all the timings were like 18-18-18-36 or something like that on those ram sticks. If that BIOS is not allowing you to set the voltage of the RAM manually, hit the Gigabyte forums and see if they have similar issues or even a beta BIOS that steps around them. God knows, I ran on a beta BIOS for 99% of my B350 Tomahawk experience. I recall something funky about the F40 revision of the Gigabyte BIOS that was tied to the Ryzen 2 stuff. I think my 470 is sitting on the F42 Bios (I will have to pull that system out of storage to look).

Yeah, if you can't manually set the RAM voltage, it's time to hit their forums and look for answers.

if its anything like the a320 GB board I just worked on, you have to just type the voltage you want. so set ram voltage to manual, click the voltage line/box/whatever and type 1.25 or whatever you want and hit enter.

IIRC you are exactly correct. I think that is what always threw me about the Gigabyte BIOS, there is no defined area to select the voltage, you just select the line item and start typing.
 
Set Profile to 1 (3200) then adjust multiplier downwards until it boots.

My GB X470 wouldn't run RAM very stable at 3200 but would do it at 3133
 
Enable XMP, and manually set the voltage to 1.36v-1.375v and ensure the clock speeds are correct after loading the XMP profile. The RAM should operate at 1.35v, but Corsair RAM likes a bit more voltage sometimes and some motherboards won't quite hit that on the RAM voltage when set to 1.35v. They'll dip a bit below that, so you want to add a little voltage to give yourself a buffer. If this doesn't work with the latest BIOS, your RAM isn't really compatible with that board. You may be able to set all the timings manually and get it to work, but that will be your last hope at that point.
 
OK thank you all for taking the time to help me, after being onto the gigabyte support and getting the run around and no help I found this video on YouTube



After following these steps I have the ram running stable at 3200mhz, voltage I set to 1.45.
Is this to high or do you think the ram can handle it?

It can handle it, but I’d shoot for 1.35 to 1.37 if it were me.
