What clock speed and voltage am I running at?

Bartek_Shady101 · Jul 4, 2018

Hey, I've built a gaming PC a while ago, and tried to clock my Adata ram at 2933 (it's rated for 3000), but I gave up. Ive come back to it today, and after a while of fiddling around in the bios, I seemingly got it to run at 2933.......at 1.25V. I don't even know if thats possible. Anyway, I looked at CPU-Z, and I found this a timing table for ram, which looks something like this:

....................JEDEC #7.....JEDEC #8.....JEDEC #9.....XMP-2998
Frequency:..1163Mhz........1200Mhz.......1200Mhz.......1499Mhz
Voltage:........1.20V............1.20V............1.20V............1.350V

Please try to simplify your answers as much as possibly, because I probably won't understand you otherwise lol. What frequency and voltage am I actually running on? I have it set on 2933Mhz and 1.25V is that correct??

Can you post screenshots from CPU-Z memory and spd sections?

If you could list your PC specs, that would be a real help. List motherboard, ram (exact model), CPU, PSU etc. We can give a more accurate answer. Systems from intel/amd differ, specially with ram.

From the limited info you've posted, having the ram run at 1.2 @2933 is possible. whether or not its stable is another thing. You could use memtest86+ to test your ram at that speed/voltage. I'd think it will prob fail. If your ram is rated at 1.35 for 2998hz, then do that and again test with memtest and see if there's a difference. I suspect you will find there is.

Then you'll know for sure.

SPECS:
Ryzen 5 1500x
Adata XPG Z1 (1x 8GB) 3000MHz
GTX 1060 6gb (MSI Gaming X)
Seasonic S12ii 520W
MSI B350 Gaming Pro

So youre confirming that Im running it at 2933mhz with 1.25v? And thanks, Im gonna check my ram stability right away.

Looks like that DIMM is on the QVL for that mobo. That's a good thing. The memory straps on that mobo, i think are at 2933, anyway so trying to reach 3000 (which is often just marketing spiel) is not worth anything at all.

The default speed of your ram is 2133/2400mhz. It's set at 1.2v and will run perfectly that way. The 2933/3000 rated speed is an overclock setting, and that's why the ram has a voltage of 1.35. You can set this on auto to run flawlessly by setting XMP Profiles or DOCP, and test it with memtest on that setting. If you find that at 2933, 1.2v it hasn't had failures in memtest or doesn't cause random BSOD's while gaming or working on the PC, then that's a result. But, I don't think it will pass, it's just too low a voltage for that speed. Practically every other DIMM on the market would be rated to run with higher voltage at that speed. Let us know anyway how you get on.

I'm not confirming your running at that!

I've only your word to go on

If you post a screenshot, then maybe I could say that!

Checking stability is the key. Make sure to do that.

edit: A note of caution. Ryzen/Memory compatibility is notorious. It's just very finicky and often means you have to set timings and voltage manually to achieve the aforementioned OC speeds.

Is there any easier way to test for ram stability? It seems like memtest is quite complicated and time consuming.

Btw thanks for replying

If you want to know what speed you're actually running at, look at the Memory tab in CPU-Z, not the SPD tab. Don't think it shows the memory voltage though, could try a different monitoring utility (maybe hwinfo64?) to see that.

The memory tab states I'm running at 1463.7Mhz, which would confirm that I'm running 2933. And thanks for the suggestion, Ill try hwinfo
