I thought I made that part clear by mentioning everything is updated, but to clear any confusions 😊 I'll specify which versions are currently installed: MB driver: 4207 GPU: 19.2.3 OS: Microsoft Windows 10 Professional (x64) Build 17134.590 (1803/RS4) RAM testing done with: MemTest86 v8.1 Free Edition (standard - preset test) installed on a Transcend 8GB USB 2.0 If I've missed anything let me know and I'll check that up as well. 🙂

The thing that puzzles me is that the RAM in question passed memtest86 without any errors, so that would make me believe that Arma3/Windows10 is using ram in a way that causes problems but is not part of the memtest86 standard test. Also on the ADATA website for configuration compatibility, my ram is listed as compatible for my motherboard B350-F Strix. On the Adata website i noticed that 16 16 16 timing is not even on their spec sheet for 2x4GB 3200Mhz RAM but that is what bios and box timings show, so i thought the timing is causing issues.. but like i said in the post i linked here: "it passed both 16 16 16 and 16 18 18 timings without a single error". Each test runs for ~1h40min = 0errors, Arma3 ~5min = total game crash... It could be Windows10 but i'll have to test other games on 3200Mhz, since web browsing/desktop works without noticeable errors (have not been playing much else these times...Arma life xD). *ram is installed properly and everything else is updated to latest drivers I'll try advanced memtest86 when i'll not be using my PC for a few hours. Is there anything else i can try?

Sharing to this thread.

Game crashes every ~5min when memory is set to 3200Mhz. Changing the speed just below 3Ghz (2933Mhz) resolves the issue. This made me think that ram is not stable at those speeds/timings, but it passed standard(1h40min) memtest86 on 3200Mhz with 16 16 16 as well as 16 18 18 timings without any errors. Custom mods are unloaded/not used when this happens, game files are verified on steam, changing parameters for memory allocator did not solve the problem. I would really like that extra fps that 3200Mhz ram gives on Ryzen. Are there any solutions to this other than lower ram speeds? Error code is something like: 00000005 "memory access violation" Hardware: (latest drivers on everything/current as of making this post) cpu: Ryzen 5 1600 @4Ghz gpu: MSI Gaming X RX 480 4GB ram: 8GB (2x4GB) ADATA XPG 3200Mhz mb: ROG Strix B350-F Gaming ssd: 240GB Samsung 840evo Software/drivers: mb: 4207 gpu: 19.2.3 os: Microsoft Windows 10 Professional (x64) Build 17134.590 (1803/RS4) RAM test done with: MemTest86 v8.1 Free Edition (standard - preset tests) installed on a Transcend 8GB USB 2.0
