Hey guys,
Long time subscriber to LTT, new to the Forum. I just recently built myself a new gaming rig (Ryzen 5 3600 (non-X) B450 build - for now at least, it's still a work in progress - full spec details in profile) and though I've been building and using computers for almost 30 years now, this is really the first time I've been able to afford to build on (still) current mid-high tier components. Always before I've been a generation or two behind when the platforms had matured and settled. This is the first time I've ever really had the ability to overclock most of the components in the system available to me. However, since I know absolutely nothing about how to go about it I'm just starting with the noob level stuff; MSI Afterburner light bumps to play around and, of course, enabling XMP profiles on memory.
When I first built the rig out I stuck in a 16GB (8gx2@3600 CL18) kit of Trident Z Neo (slots 2 and 4, of course) and after getting everything up and running, updated, verified as working and stable, I enabled XMP Profile 1 in the BIOS (Gigabyte B450 Aorus Pro Wifi - Updated to the latest/current F50 BIOS version) and I was instantly gratified with a boost to 3600Mhz which ran stably for weeks - minus glitches while playing around in Afterburner here and there.
The problem arose today however, when I expanded the kit with an additional 16GB kit of matching CL18 Neo's - first time I've ever filled out all the DIMM slots on a motherboard of mine since the halcyon era's of 286 through Pentium II when you could still find PC's with Turbo's (you old timers know what I'm talking about ) equipped.
Booting straight into BIOS everything registered, though it did say my settings had been reset - I did have to remove all the memory to get everything installed comfortably - the Wraith Max cooler butts right up against slot 1 so I removed all 4 modules and slotted them in from 1-4, keeping the original kit in their original slots. I flipped XMP back to Profile 1 again and verified all else was as correct as I could remember before saving and restarting. Problem is it's not holding in Windows, the memory is running at it's stock 2133 Mhz. I'm sure I'm missing something in BIOS - XMP profile is enabled, it's just not taking in the OS.
I vaguely remember an issue like this when first getting the original kit running and I can't remember if there's something to do with infinity fabric settings in the bios, switching it away from Auto (which everything is currently set to) but I just can't remember. Any suggestions I could try out? Thanks in advance!
