Question Adding extra ram makes games and pc crash

[Sm_key]

So I recently upgraded my RAM from 16gb to 32gb. I bought the exact same kit I already had (Corsair 16 GB DDR4-3600 Kit, CMW16GX4M2D3600C18) with XMP enabled and voltage at 1.35V. For some reason after gaming for like 15 mins or so my game crashes and rarely my pc crashes. I searched some things up and saw someone with the same issue and he changed sum in his voltage in the bios but it wasn't really clear. It might be bad memory, but memtest said it was fine. Please help

So even though you matched the the ram, it can still cause problems. Try removing the older set of ram and see if the behavior continues. Then repeat same with the new ram and see if it continues. You may have to buy a 32gb set of ram. Another thing to check is to see if there is a newer bios that addresses ram.

You did not buy the exact same ram.
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.
Ram must be matched for proper operation.

You can sometimes compensate for errors by increasing the ram voltage in the motherboard bios if you have a motherboard that permits such settings.
With a functioning 2 stick kit installed, increase the ram voltage in steps above the nominal 1.35v. You may need to go past 4.0.
Then install the second kit and run memtest. A full pass with NO errors and you may be ok.

Your real solution would be to return/sell what you have in favor of a 2 x 16gb kit.

The 2nd kit you bought probably is very different. What's the version number of both kits?

You are showing laptop ram.
The op has desktop ram.

I tried taking the new sticks out and it didn't wanna boot anymore, so i put them back in and now it booted

one set is 4.33 and the other is 8.31, i didn't know it caused issues

I think you meant 1.4 and not 4.0v?

I do not but it's just an example where to find the version number.

4.33 has Samsung MIC and 8.31 has Nanya MIC. You're mixing RAM in a hard way and if you're system is a AMD Ryzen it's hard to run 4 sticks in the first place, even if they're from the same kit.

I can cause issues, depends on how tight the timings are. What you can do instead is disable XMP and have it run in default timings. If the problems disappear then it's likely timing related and you'll need to tweak it to make it work. "Matched" sets have already had this done and those pre-tuned timings are what is given to XMP.

I do not see any processor or motherboard specs, but if you are running Zen 2 / 3 max RAM speed over 4 sticks is 2667MHz. Zen and Zen+ will be correspondingly lower.
