Just reciently bought the Ryzen 2400g. Also bought some G.Skill Ripjaw V 3200mhz RAM. In the bios it says its running at 2133mhz, it gives me the option to go up to 3200mhz but it crashes. I did not play with the voltage cause i'm not very informed on that stuff. I would think it would preset to 3200mhz.

What do I need to do to stability get my ram to 3200mhz? I know I need to slightly increase the voltage but is there anything else?

2x4GB 3200mhz

If you are basing your observation on the QVL, don't. The QVL is a select few models tested, it's not gospel. That ram is most assuredly viable ram that'll be supported by the mobo. They'll test 1 model but not another because model numbers change with something as simple as color. There's exactly no difference between the blue ram, red ram or black ram. Just the color. So they will not test all 3. There's 50 different vendors, 1000 different models, 10 different heatsink designs, 5 different colors, RGB, 20 different speeds and timings and 100 million combinations. If they verified all 100 million combinations of ram, the QVL would be 10000 pages long and take years to compile.

The issue isn't the ram, it's been vetted by multiple...

I will try using the XMP profile when I get home, again im not to informed with this stuff this is why im reaching out. Yes my ram is on the support list.

Default speeds for ddr4 ram is 2133MHz. If you have a kabylake cpu, ram can run at 2400MHz stock, CoffeeLake is 2666MHz stock. If the motherboard has capacity to run faster than the cpu used, you'll need to use XMP profile found in bios to change the speed/timings from default to rated speeds.

velocityg4 is correct, when you put in ram in a motherboard, it will always run at base speed of the cpu's memory controller not the quoted speed on the memory itself. People always get confused on this topic. To enable the quoted speed on the memory you have to go into bios and enable the xmp profile for the quoted memory module speed and restart. If the cpu's memory controller supports that quoted memory speed then it should post up at that speed.

I tried the XMP profile at 3200mhz and it bluescreens after about 10 seconds (right when its about to load into windows). I've played with the voltage and still cant find stability. I'm running currently at 2666mhz at 1.35V and it runs smoothly but now im encountering random game crashes out of nowhere and bluescreens randomly, I haven't found anything that triggers it. I was going to try to turn the speeds back down to 2133 to see if it would stop the random bluescreen but when my PC loads up now the screen wont turn on till im in windows therefore I cant access the bios.

Edit* It runs fine using it as a normal desktop, I encounter these bluescreens randomly when playing games after about 40 mins, sometimes sooner, somtimes later.


**since this og post ive added a GTX 760 to my build, I may try returning to Vega to try and get into the bios**

There'll be a cmos button or jumper to reset the bios back to default settings, if not, pull the battery on the mobo and count to 10. Pita, for sure.

3200 is not a stock speed. It's listed as OC. This means that you'll either need to OC the ram or cpu or both. But the timings on the ram must be pretty close if not the same as listed on the ram. Dl a program called cpu-z. On one of the tabs (I believe it's SPD) at the bottom will be a table listing the available speeds of the ram. It's listed as single data rate not dual data rate (ddr) so 3200 will appear as 1600. For 2666MHz you'll want 1333. That'll show you the primary timings for the ram. In the bios, when you set the cpu OC and or ram speeds make sure the timings are also set for the speed you want.

A handy basic guide. Names may or may not be the same, but the affects are identical, as is the theory.

When you say timings can you elaborate? Not sure what you mean.

I see the timing tables, should I adjust it to the voltage it says?

Timings are the 4 numbers associated with the ram. So 15-16-15-37 etc. Those change with different models etc. They basically represent the gates to the ram, how fast they open/close and allow data through.

But yes, if the table says 14-14-14-35 for the 1333 (2666MHz) then that's what your ram should be set at. XMP profiles will set those automatically, so if you happen to have xmp1 and xmp2 etc for 3200 and 2666, then it'll set it for you, including any necessary voltage. But thats just the ram. You'll also maybe need to bump the sa agent (sb voltage or whatever it's called) to increase the memory controller (really small bump, 0.05v etc) and/or give the OC on the cpu a little edge.

If you raise one part by OC, there's a really good chance you'll need to raise others to match and maintain stability. There's not just a simple one-click OC.

At what point do I stop, what is to high to avoid damaging my parts.

Ideally you'll be keeping voltages as low as possible and still maintain stability. If you look at the dram voltage xmp sets for 3200, then you really shouldn't need to go much if any beyond that. AMD recommends not going above 1.4v. My dram is stock at 1.5v, but because of OC its set at 1.505v. It really doesn't need much at all, an that's taking ddr3 rated at 1600, manual OC to 2400MHz. Your ram is rated at 3200 so taking it from 2133 to 2666 or 3200 should still be within stock voltages.

I looked up your memory, it is *NOT* supported by the motherboard for overclocking to 3200. Try looking for an xmp setting closest to 3000, that speed is supported for gskill memory. Probably going to come up like 2999 or something close to that I believe.

According to Asus, the B350 F supports upto 3200MHz (OC) just fine. As long as op has a latest bios upgrade to ensure that the ram is compatible at 3200 there shouldn't be an issue.
Op might have to adjust other settings in the bios with some OC to allow the memory controller to keep up with the ram running at higher speeds. That's the (OC) listed on the ram compatability. It's highly doubtful you'll get stock/default cpu/bios settings to allow the ram to rum at OC speeds by itself. Basically you gotta take the training wheels off the cpu in order to race.

Leave ram at 2133
Oc the cpu to stable limits
Bump ram to 3200, shouldn't need any voltage adjustments.

His ram is not supported by the motherboard drivers thus he will not be able to overclock the memory to 3200. The 3200 spectrum is very narrow in support of any ram modules, let alone non supported ones.

The issue isn't the ram, it's been vetted by multiple sources. The issue is simply the OC isn't viable in default settings. OP needs to OC the cpu correctly and set bios settings correctly on stuff other than just the ram voltages.
