[SOLVED] XMP Issues

[Maxvj]

Hello, I am having issues overclocking my RAM with A-XMP, when I select A-XMP to 3600mhz, it will clock to whatever the DRAM frequency is set to. So, I selected DRAM frequency to auto, but then it runs at 2133 mhz.

RAM: Corsair RGB pro 3600mhz
Mobo: Msi B450 Tomahawk MAX.

Thanks, everyone.

What you describe is the way it's supposed to work: XMP should clock the ram to whatever was preset in the DIMM's. But just putting it on AUTO will run at default DDR4 clock speeds which is usually either 2133 or 2400.

What is the problem? or what are you trying to do?

I am just trying to run my ram at 3600mhz.

It sometimes helps to start with clean BIOS settings. You can do that either with a CMOS reset or load Default Settings in the BIOS save and restart screens.

Once CMOS is reset, just go to the A-XMP settings and set profile 1 or profile 2, then reboot. It may have difficulty booting; I find it helps with mine to set the DIMM voltage manually to the required voltage. Get that from the package. If even that doesn't work, use a higher DIMM voltage. DDR4 is safe up to 1.5, but don't go higher than 1.40 except to 'see if it works'.

and do keep in mind that 3600 isn't always possible, although Ryzen 3000 CPU's are much more capable they're still rated only to 3200. It may be necessary to tweak the advanced timings (put the BIOS in Expert overclocking mode to see them). You can get help with 1Usmus' "DRAM Calculator" tool to help with calculating the timings to use based on your memory, CPU generation and motherboard.

Ok will do

So I did this, and it still didn't work it ran my ram at 2133 mhz

Enter BIOS, click on OC , on the XMP profile change only that to enable, save and exit.

Yours might be a bit different worded I'm on a Z490 tomahawk

my xmp seems to match whatever my dram frequency is, and it won't clock to 3600mhz, but I have had it to 3600mhz before (using xmp), but I unplugged it because it wouldn't connect to msi mystic light software, then these issues started to occur.

that's confusing since you say you have Corsair RGB Pro 3600Mhz memory...so XMP should match that.

 

[Maxvj]

yeah, i pulled out my ram and plugged it back it, the dram frequency was switched to auto, and right below it said that the adjusted frequency is 3600 mhz, because axmp is on, booted it up, and task manager still says 2133 mhz.

Just did a bios update, no change still will only run on dram frequency settings, but won't boot at 3600 mhz.

What does CPUz say it is?

Also...after the BIOS update be sure to reset CMOS

No... CPUz, the utility.

You may need to tweak timings to get 3600 stable. Even though BIOS is telling you '3600' it might be failing to train memory during POST and reverts to a slower default.

You can try to set the primary timings and voltage manually (it should be on your DIMM package) and as well setting the speed manually. Setting advanced timings will require learning how to use the DRAM Calculator utility.

ADDED: MSI BIOS' also have a 'try-it' that has some fairly loose timings for various clocks. You can try those too; even if you can't get 3600, something lower like 3200 might work well enough. 3600 is not always a sure thing.

Ok I can give it a shot, still weird since i have had 3600mhz work before, plus it posts at 3466mhz. Thanks.

 

[Maxvj]

CPUz also confirms the clock speed i will mess around with more advanced methods of overclocking besides xmp. thanks
