What are the best settings from my RAM?

So a while ago I started having BSODs. I disabled any overclocking I did and just left my RAM at 3200Mhz by enabling DOCP and leaving everything as is. So no voltage changes, nothing.After many hours of troubleshooting, I finally decided to run Memtest86 which aborted the test due to too many errors. I thought the RAM is faulty for sure, so I consulted here and on other forums about what are my options.

The main suggestion was to test whats at fault exactly, so for my testing:

1. Pulled out one RAM stick, ran Memtest86 (which took 2 hours to complete), 0 errors. At this point, I thought the other stick is faulty, since previously it aborted the test after over 10k errors! But I continued.
2. I swapped the working stick from the previous stage and inserted him to the "faulty" one's slot. I thought it might also be the MB slot. Ran the test, 0 errors. So I concluded both slots are fine, which only leaves the stick.
3. I inserted the "faulty" stick back and ran the test. Once again, 0 errors.

Now I'm wondering two things:

1. Why was I getting over 10k errors in my first ever test which I ran a few weeks back, but now everything seems fine? Could it be the stick wasn't inserted properly?
2. Now that there are no RAM issues, even when I leave the speed at 3200mhz, what settings can I change to make it as stable and as factory recommended as possible?

Here is my rig:
Ryzen 5 3600
ASUS TUF B450M Plus Gaming
Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16
EVGA RTX 2070 SuperAntec EA750G Pro 750W Gold
Win 10 Pro 2004

Here are some screenshots from CPU-Z:



I'm afraid to touch settings in the BIOS without confirmation from more knowledgeable people. I read that I can change the voltage, tRC, and a few other settings to make sure my RAM is as stable as it gets, while still running at 3200mhz.
Any tips would be great :)​

You are overclocking, the XMP profile as you see is 3200 MHz and at a higher voltage 1.35 V.
The chip specs are the JEDEC profiles which are up to a max of 2132 MHz at 1.2 V, profile #8.

That is a large overclock. The thing is, has Corsair actually used chips from a higher performance bin in these memory modules.
To run at rated frequency you would use the max JEDEC profile #8 at 2132 MHz.

The fact you got errors is not so surprising using the XMP profile. Whether these are 'faulty modules' is a grey area.

Testing modules one at a time does mean much. When you use 2 they are in dual channel mode assuming they are in the correct sockets.
Even then there will be slight electrical differences depending on the MOBO for the different pairs of slots. Modules do not work in isolation from other MOBO components either.

Other people's modules will be from different production batches, so minute changes in timings are highly unlikely to be any use to you.
You have to remember that these minute changes, even if possible to do reliably, will have no measurable effect on your PC performance.

Thanks for the detailed reply, but what do I take from the eventually? Do I reset everything to stock and leave it as is? Can't I use 3200Mhz at all without BSODs?

I agree.


From 2132 to 3200 is a 50% overclock. As you're having problems, I would set it to run at base frequency (2132) to see if you don't get the freezes or BSODs.
- You can manually set a frequency, timings and voltage, lower than XMP.
- You can call Corsair and ask for suggestions and / or a replacement.

Maybe I'm missing something, but isn't the whole point of having a 3200mhz supported Mobo + RAM means I can comfortable use 3200mhz? Or was I supposed to buy RAM that has 3200mhz as the default frequency?

As far as I know, no RAM has a 3200MHz default frequency.

The QVL (qualified vendors list) for your board (TUF B450M-PLUS GAMING Memory / Device Support | Motherboards | ASUS USA) lists a version of the Corsair RAM. I wonder whether yours is the same version? (Shouldn't matter, but Asus tech support might give you a hard time if it isn't. If you could reach them in the COVID era.)

I have a different board (Tuf Gaming X570 Plus). I didn't do RAM testing, but using DOCP caused frequent restarts when I went to BIOS 2407. (It was OK with earlier versions.) I'm now on 2607, and things seem OK.

You may be able to get 3200MHz by adjusting the RAM timings. I'd start with backing off on the latency by a tick or two. (I'm no expert. I haven't played much with timings in a few years. I did it mainly to get some unmatched RAM pairs to run stably together.)

Yes, you're right, BUT you're having issues. As I wrote before:
