Posted October 31, 2019 Hey all, A few months ago I built a new PC with a Ryzen 7 2700X, 16GB (2x8GB) Corsair Vengeance LPX 3000MHz RAM, and a B450-F STRIX GAMING. The other day I upgraded my GPU and bought an identical kit of RAM to put in my system in slots 1 and 3. (Others identical set was in 2 and 4 as per mobo manual). Suffered a series of game crashes, blue screens, and general slowed running of my PC until it got itself into a major bluescreen loop of turning off, booting into a bluescreen.. etc.. Took the additional RAM out, and everything has been fine ever since (phew it was only the £70 RAM and not the £500 GPU). Sent the RAM back to the shop I bought it from and just thought it was a bad batch of RAM. Looking into buying another set or RAM now, I've been thinking about compatibility on a closer level. On the returned version, Latencies, Speed, Model SKU, even the RAM Version was identical. So decided to look at my Motherboard's Qualified Vendor List for RAM. It shows support for my RAM on there but not as a 4-DIMM, two pair arrangement - is this really that big of a deal that it would have definitely caused this? Or should I chance it with another identical set?

Posted October 31, 2019 Have you tried with different ram speeds like 2933? I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B Primary PC: i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me. Draws 400 watts under max load, for reference. How many watts do I need?

No I didn't, I've sent the second set back now, however since posting I've read a few places that Ryzen 7 2700X have a max RAM speed of 2933 MHz. I just assumed that since I was running my 2x8GB at 3000MHz for a few months without a hitch, adding DIMMs for capacity wouldn't affect it. I think I'm going to call it a loss and buy a 2*16GB 2666MHz set on the Qualified Vendors List for my motherboard and run them at 2666MHz. I'll return them (again) if they don't work and use my trusty ol' 2x8GB. (Incase you're wondering why I'm so desperate for more RAM, I do a bit of content editing, and Prepar3d, a flight simulator I use is super RAM hungry) Thanks for your input!

Posted October 31, 2019 I have been having the same issue. I have a 2600x on an Asus ROG Strix B450-f and with 2x8GB Gskill Ripjaws 3200 CL16 sticks it ran fine for about a year. I got 2 more of the same RAM and then I had a ton of memory related BSODs. I dropped the speed to 2133 and only then was it mostly stable. Now when I take those sticks out I can't run the 3200 XMP profile I had running for a year. I can't figure out if I need a new board or CPU or what.
