Hi everyone, I am trying to activate XMP on my computer through the UEFI interface however I get the error saying that the "previous overclocking settings have failed". Sorry for the long post but I do believe that "devil's in the details", so here is some context to the issue: I had this build for a bit more than a year and about two weeks ago I decided to buy an additional kit of RAM (2 x 16) and use it along with the existing one (2 x 8). When I first built the pc a year ago I activated XMP from day one and I had no issues with it. Two weeks ago when I installed the new kit I didn't touch the XMP setting. Then I also ran the bootable MemTest86 for about 2 hours and no errors where found (I am aware that this is not prooving that the RAM is perfectly good). However, I started to experience crashing in games, I played a lot of Snowrunner the past days and I get a crash every 10-40 minutes. When inspecting the log of the crash it says "The thread tried to read from or write to a virtual address for which it does not have the appropriate access". I also tried GTA 5 which I played a lot before installing the new kit without errors, and I was, again, "greeted" with a crash in less than an hour of playtime, inspecting the windows event viewer I discovered that the crash was caused by a "Faulting module name: nvwgf2umx.dll". I decided to go and turn off the XMP setting in the UEFI. I did that and I managed to play Snowrunner for 6 hours and GTA 5 for about 4 hours with no crash or errors. Then I went back to UEFI to turn on the XMP and I was greeted by the "Overclocking settings have failed. Press F1 to enter setup. Press F2 to load default values and continue". I, then, tried a lot of different approaches (like manually setting the voltage to 1.35V or modifying the timings) with no luck, I couldn't turn the XMP on. I did, however, manage to turn it on one time through the MSI Dragon Centre's DPC Latency Tuner, but again, Snowrunner crashed after 15 minutes. I turned XMP back off, and when tried to turn it on again it failed no matter what I tried (UEFI of Dragon Centre), the same "Overclocking settings have failed" error was shown and one time I even got a blue screen with "Your PC needs to be repaired" message. <----- PC Specs-- ---> CPU: i9 9900K (no OC, just default/stock speeds and settings) MB: MSI MPG Z390 GAMING EDGE AC GPU: MSI RTX 2080 GAMING X TRIO OS: WINDOWS 10 Pro 64bit MEMORY: ->the original kit (used for the past year): Corsair Vengeance LPX 16GB (2x 8GB) 3000MHz DDR4 - CMK16GX4M2D3000C16 ->the new kit: Corsair Vengeance LPX 32 GB (2 x 16 GB) 3000MHz DDR4 - CMK32GX4M2B3000C15 PSU: Corsair HX Series HX750 750W 80 Plus Platinum Full Modular STORAGE: -> Samsung SSD 970 EVO Plus 500GB (where the OS is installed) -> Samsung SSD 860 EVO 1TB One thing which I would also like to mention is the layout of the RAM stick in the DIMM modules. They are placed as follows: DIMMA1 - 8GB (old one) DIMMA2 -16GB (new one) DIMMB1 - 8GB (old one) DIMMB2 - 16GB (new one) Here is the CPU-Z report uploaded using the Validate button: https://valid.x86.fr/8phihj And here it the full HMTL CPU-Z report(hosted on GitHub): https://mateigiurgiu.github.io/pcspecs I know I should be doing a clean reinstall of the OS, however, I am a couple of weeks away from my master's dissertation deadline and a clean reinstall will set me back 2 or 3 days because I need to reinstall everything I use. I also discovered that the old kit I was using doesn't appear in the compatibility list on the MSI page (https://www.msi.com/Motherboard/support/MPG-Z390-GAMING-EDGE-AC#support-mem-3 ), however, the new one does appear. My idea is that the kits are somehow incompatible with each other when using XMP, or the MB is not smart enough to set the latencies or other settings as it should. I also noticed that they have different SDRAM Manufacturers: Samsung vs SK Hynix. If would like to know if the kits are incompatible or if the new kit is faulty in order to return it within the 30 days period. What are your thoughts about this?

I've got a 512 GB M.2 970 Evo on its way. Thank you for the suggestion. I managed to solve the problem by limiting the FPS. It seems to be a high FPS problem. If it goes above a certain point which I discovered to be ~165 it starts stuttering. That's why it happens mostly in the interior (such as Michael's House) because due to occlusion culling I can hit higher framerates. I also found this to be linked to the issue: And according to this, it is a bug of the engine when hitting 187.5 FPS:

My SSD only has Windows, the basic utilities such as afterburner and dragon center and GTA 5. There is no way I can free up more space. However, I made a test with very low settings and the issue still persists.

Regarding the SSD being full. It might be this or it might not. I have to wait for the 970 Evo and test with it to be sure but I suspect this is not the issue because I tried enabling V-Sync which limited the FPS to 120 but the stuttering appears to be gone.

Hey guys, I recently upgraded from my Asus ROG laptop to a custom build PC but I have this issue with stuttering in GTA 5. I can't say it happens with a specific pattern but I noticed it is worse when in Michael house. If I go outside it happens at random times but sometimes I can play without stuttering for 20 minutes or I can happen much more often. I made a video with the issue: https://youtu.be/oEEgD7UAHkg (Graphics Settings at 1:35) SYSTEM SPECS: CPU: i9 9900k (no OC) AIO: Corsair H100i RGB PLATINUM MB: MSI Z390 GAMING EDGE AC RAM: Corsair Vengeance LPX 16 GB DDR4-3000 CAS LATENCY 16 GPU: MSI RTX 2080 8 GB GAMING X TRIO PSU: Corsair HX Platinum 750W (set on Multi Rail) STORAGE: Micron 128 GB (just a temporary SSD that I had available, the 970 Evo ordered is in transit) MONITOR: Alienware AW2518HF 24.5" 1920x1080 240 Hz (G-sync compatible) OTHER MENTIONS: - No OC to the CPU, I left BIOS settings to default. - I enabled XMP for RAM in bios - I set the RAM voltage from the default value of 1.200V to 1.350V - I tried using Game Boost feature of the MSI mobo but it didn't help - Since I only have that 128 GB SSD the space left in ? is ~1 GB or less - I tried this with both G-sync compatible option on and off Can you please give me some suggestions about what can cause the issue? Thank you in advance.
