Question Ram will not stay at 3200mhz.

[dragochief]

I've tried everything, changing the timings, changing the voltage, and with or without XMP. Nothing will Work. I just recently got 16GB of Corsair Vengeance Pro RGB to add to the 16GB I already had (they're the exact same kit, different boxes; same spec). I followed another troubleshooting thread on here, it said it worked for them but it had 0 effects on my system.

Specs: R5 2600, Zotac RTX 3050 8GB (sad, I know), b450 steel legend, 32GB 3200mhz Vengeance Pro GRB, Kingston M.2 NVMe SSD (120gb), Random ass 1tb HDD x2.

Ryzen are much more sensitive to non matched (boxed) kits than Intel. In addition to that aspect, it's not unusual to have lower performance when using 4X as opposed to 2X. Try lowering the speed to 3000 and see if it works for you. The motherboard VRM are having to support twice the memory power as before.

I have tried 3000 and it didn't work, just updated my bios as well. That did nothing. If you have any other suggestions I'm all ears.

Basically, keep lowering speed and loosening timings until it works IF it works. Being a matching, but not matched set could be the whole issue. Do these exact sticks show on your motherboard QVL?

Making assumptions that since you have tried timings and such the PC will at least boot to BIOS. Can you get into Windows?

If so, install CPU-Z and jot down some of the JDEC/XMP timings and voltage shown there for the lower speeds and use those.

This is what I was able to find. Am I meant to set the frequency to 1600MHZ?

DDR, so 1600 is actually the 3200 speed your kit is rated to XMP at. You mention that hasn't worked, so would probably go lower on the table and see where it becomes stable.

 

[Unolocogringo]

Your kits might be the same brand/model, but they have different timings.
JEDEC #18 24.0-15-15-36-50 @ 1066 MHz

XMP #18 24.0-18-18-36-54-n.a @ 1600 MHz (1.350 Volts)
They MIGHT work together but you will need to do trial and error on timings and voltages to get there.
Try setting manually them to the slowest of the 2 .
24-18-18-36-54 . And 2933 speed for the 2600. Which is only guaranteed to work with 2 sticks.
You may need to drop speed lower to get 4 sticks running. Which is normal.
Have a read here, especiall the section ODD Man OUT.

I am not sure how you are asserting this given the table appears to be the reported on one stick. Am I misinterpreting something?

Top table is JEDEC and lower is XMP which typically are different. CPU-Z (and others) report both.

give us full name and model of ram one is working at 1.35 volts what about the other mixing ram could lead to issue even from same brand

Will it boot with just the new sticks?
If so post the timings of the new pair along with the old pair. An auto bios screenshot so we can see all timings. not just primary.
MAYBE with both we can figure timings that might work.

Yes, It will boot with the new sticks by themselves.
I just got a new motherboard (not related to this problem, it's a b550 Gaming Plus from MSI) that has options for 3200mhz and different timings, I have tried all of the timings and none of them work.
When I use two DIMM's worth of ram (no matter what box I got it out of) it will boot at 3200mhz. But, when I use 4 DIMM's, it activates Memory Fail Boot and sets my ram to 2133mhz.

Edit: I think I've narrowed it down to my CPU being the problem. I might invest in a new one. This 2600 is getting old. (italicizing is stuck on help)

Yes, that's mos certainly the case, IMC is just too weak for 4 sticks at higher speeds. Ryzen 5000 has no such problem, in some cases and on 500 chipset Mbs it may even give better performance with 4.

Guess I found the issue. Cheers!
