Hey everyone! I bought this PC back in 2013 and decided to give it a RAM boost before I can't buy the stuff anymore... I know... it's old... but it still serves a great purpose for gaming and will ultimately be my personal Minecraft server for family members. Specs: Intel Core i7 4930K Ivy Bridge-E @ stock 3.4 GHz Asus X79-DELUXE PCI-Express 3.0 RAM (new) - DDR3 4x G.Skill F3-1600C9D-16GXM (with 4 more on the way) - 32GB total in QUAD Channel (yes, really QUAD, not Dual x2) Radeon RX 580 8GB Corsair Air 540 case with plenty of air cooling Cooler Master Hyper 212 (or something similar) - plenty of cooling for stock! All drivers and BIOS are up-to-date. So I bought this thing with the intention to overclock but never have... hence the extra cooling case. This thing had F3-12800CL9D-8GBXL G.Skill RAM (4x 4GB 16GB total in QUAD Channel) and ran flawlessly for years. I recently started hosting Minecraft for my children and nieces/nephews (and me too!) just to have family time. It's been great... These minecraft servers eat RAM so I decided to upgrade the ram from 16 to 48GB. I was using the F3-12800CL9D-8GBXL G.Skill RAM (4x 4GB 16GB total in QUAD Channel) in addition to 2 sets of F3-1600C9D-16GXM for a total of 48GB of RAM. Yes, I know mixing the rams was a gamble, but they had identical timings and speeds (DDR3-1600 @ 9-9-9-24 @ 1.50V). I figured it would work great. Loaded the 4 new RAM (total of 8 slots all filled). Yes, I followed the motherboards guidance for the RAM slots to use for quad channel. Booted the BIOS - turned on XMP, and booted windows fine. Ran Prime95 Blend with no issues. Started to play games - Dirt Rally 2.0 - crashed... The Forest - crashed. So I took all the RAM out, and then installed JUST the new F3-1600C9D-16GXM in the proper Quad Channel slots in XMP (now only 4x the new ram installed in quad)... Again crashes during games... When I turned off XMP, the RAM runs at 1333 MHz and it ran with no issues and the games run fine with no issues. What is going on here? I looked up videos on how to tweak RAM, but honestly this Asus X79 has so many overclocking settings it is rather deep. I always wanted to manually dial things and tweak things but never dove into it. I know it's an art and it takes patience, but honestly this thing runs like a beast and I never needed to do anything other than upgrade the video card to support larger VRAM requirements. I am very advanced with computers, although I just never dove into the deep BIOS settings to tweak everything. With the advent of Turbo modes and multipliers for the CPU/RAM etc, I just figured I'd leave that for a rainy day... Perhaps it's that day. Can anyone explain why this is happening and what I gotta do to get these RAM chips to at least run at their rated XMP profile speeds? I tried manually increasing the DRAM voltage to 1.55 just to see if that would help, but I still got crashes. I attached some screenshots of CPU-Z and MaxxMem. I ran benchmarks at 1333 and 1600 MHz.

It's curious how adjusting the voltage only slightly affected the benchmark results. While playing games caused crashes, increasing the RAM speed to 1.55 resolved that issue. However, after changing settings, the audio became distorted and the games stuttered. I suspect there might have been problems with the original RAM configuration. After switching back, the old RAM worked fine, and MemTest86 reported no errors on the new setup. It seems a memory controller problem could be the cause. I'm still trying to figure this out.
