xmp not work. even at 2666 mhz my pc will bluescreen at some point. tried using the calculator, watched some tutorials about it and still it not work.

I have 2 x 4GB sticks and I put them in slots A2 & B2


Edit:

Specs
Motherboard: Asrock B450 Steel Legend
CPU : Ryzen 5 2600
GPU : RX 570
RAM : 2 x 4GB VGEN 3200Mhz
PSU : idk the details, my father gave me (but i know its bronze)

i did install the latest BIOS version.

Edit 2:
my PSU is Lux Aerocool 550 W bronze

Welcome to the forums and Happy New Year, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

I have a similar Ryzen 2600X. It was perfectly happy with 2 x 4GB rated at 2400MT/s, but when I installed 2 x 8GB 3000MT/s, the system would not boot.

I fixed it to run a 3000MT/s by diving into the Primary Timings and "relaxing" the CL/CAS speed on each DIMM by 2-clock cycles.

If your V-gen is rated at CL=32 for 3200MT/s, try increasing it to CL=34 in the BIOS for both DIMMs. This slows down the RAM slightly, but you probably won't notice any difference.

Your 2600 and my 2600X are only specced up to DDR4-2933, so anything faster (3000MT/s, 3200MT/s) is down to the Silicon Lottery, or careful tweaking.

If you still can't get 3200MT/s to work, try 3000MT/s (and increase CL/CAS by 2 clock cycles over the values held in SPD).

I would say that particular ram does not like that motherboard. I have never had an issue running DDR4 3200 with G-skill ripjaws and Asrock B450 boards, even with R5 1600's, and cheap B450M pro4's. As you really don't have enough ram anyway, now would be a good time to upgrade. Do need that exact PSU information though too. If it is not a quality unit, it could be causing issues as well.

my ram is 16-18-18-36

tried increase CAS to 18 with XMP on, DRAM Frequency at 2933 and DRAM volt to 1.35

not work

I've been thinking about upgrading to 2x16 actually. but i dont want to see my new ram run at 2400 ☺️

and i just found out my PSU is lux aerocool 550w bronze

that G.Skill ripjaws actually cost $133 in here, and i only have $60ish budget, thanks for the recommendation tho

Are these ram sticks a kit or 2 separate sticks you bought?

Use just one stick in slot a2.....test.
Then try the other stick in slot a2.....test.

okay i did try, and here is the result.

i put the first stick and run it at 2866mhz with xmp off and 1.35V and it works fine. i tried open my apps for daily task which is 33 tabs of chrome, spotify, whatsapp, steam, discord, tradingview app and got no bluescreen.

tried for the second stick but i test it on 2800mhz (was changed from 2866 to 2800 and forgot to change again) and im not testing it at 2866mhz. open the same tasks as before and got no problem (i assume using 2866mhz will got no problem either)

but after ~10 minutes of afk, my pc suddenly bluescreen :/

tried run at 2933mhz (forgot which stick) and got instant bluescreen

Just to get windows out of the mix put a copy of memtest86 on a flash stick.

Boot the stick and use it to test each ram stick.

You might also want to test using standard ram speeds.

2400/2666/2933/3000/3200 for testing with memtest.

I tried using both RAM sticks in the A2 and B2 slots. I didn't test with a single stick because I saw someone comment that it doesn't make much difference. If it’s really important to test with a single stick, I’ll do it later.

Here are the results:
  1. Testing both sticks took about 1.5 hours per each test
  2. No errors were found at 2400 MHz.
  3. at 2866 MHz with 1.35V,10000 errors were found within the first two passes. The test eventually failed and stopped on its own
I didn’t test at 2933 MHz or higher because if 2866 MHz already produces errors, there’s no point in testing higher speeds, right? (2933 and 3000 MHz won’t even run, so it’s likely they would show the same errors, right?)

I also tested my friend’s RAM, which is 2x8GB running at 1.2V (mine is 1.35V, as listed on the RAM). I was able to run it at 2933 MHz, and even under heavy usage while gaming, there were no blue screens.

I tested my RAM on my friend's PC, and it worked fine at 2866MHz or 2933MHz with a single stick. However, when I tried using both sticks, his PC wouldn’t turn on. I didn’t bother troubleshooting or figuring out why because I was too lazy at that point.

If replacing my RAM is the only solution, what specific factors should I consider to ensure that the new RAM doesn’t get stuck at 2400MHz? For example, should I look at the RAM’s voltage, speed, compatibility with my motherboard, or whether it’s on the motherboard’s QVL (Qualified Vendor List)? Are there any other key details I should pay attention to when choosing new RAM?

Try these timings
1499.1 MHz (DDR4-2998) - Ratio 3:45
Timings
15-17-17-34-50-1 (tCAS-tRCD-tRP-tRAS-tRC-tCR)

Sorry, man. I know I said I’ve learned how to use the RAM calculator before, but to be honest, I was just following someone’s instructions, not really studying it. So, I can’t figure out some of the things you mentioned.

I don’t see 2998; the closest DRAM frequency available here is 2933. I also can’t find the Ratio setting anywhere. Is tCAS the same as "CAS# Latency (tCL)"?

There are two tRCD options: tRCDRD and tRCDWR. Which one should I change, or should I adjust both?

I can’t find tCR, but I was able to locate tRP, tRAS, and tRC

The reason for test one stick at a time is to see if it's just one stick that has a problem.

Go here and run the scanner see what it shows.

After browsing and trying to figure all this out, I now understand everything but the ratio.

Where can I find or change my ratio to 3:45?
