How To Setup New Corsair Ram On Rog

I have a ROG pre-built system I just upgraded to two 32GB sticks of Corsair memory a (I'm maxed out now at 64GB total). These are the new sticks I purchased on Amazon, and their same page on Newegg.

The new sticks are faster (at 3600MHz), supports XMP 2.0 and are a better, more reliable brand (being Corsair). Everything booted up fine, but I'm not seeing any changes/upgrade in Windows 11 or in my bios. I expected the speed listed in the Task Manager > Performance > Memory screen to show a significant jump, but it didn't. In fact, it went down. It was at 2400 MT/s, but now it's only reading 2133 MT/s. This should be 3600Mhz (if I'm understanding this correctly).

I have also double checked they are installed into the A2/B2 gray slots on the board. And tried a CMOS reset by pulling the battery and draining power for about an hour (but no change).

I did check the BIOS, and found a D.O.C.P setting under the AI Overclock Tuner setting (which is set to AUTO by default, so I changed to D.O.C.P.) It seemed like it was going to work great at first, because it auto populated all the values in my bios (detecting and auto setting the memory speed to 3600MHz). But unfortunately, it failed the post and returned me to the bios (also something I read has happened to others).

I'm assuming I simply haven't configured them correctly yet, so that is where I need help. Here are all the specs for my system and the ram sticks themselves (plus screenshots), if someone can advise. Thanks!

My system specs:

• Processor - AMZ Ryzen 9 5900X 12-Core Vermeer 3.70GHz
• Motherboard - ASUSTek G15DK 1.0 (latest 305 bios installed)
• Chipset - AMD Ryzen SOC (listed as AMD® B550 Chipset on ROG's website)

New Corsair RAM specs:

• Brand CORSAIR
• Series Vengeance LPX
• Model CMK64GX4M2D3600C18
• Capacity 64GB (2 x 32GB)
• Type 288-Pin PC RAM
• Speed DDR4 3600 (PC4 28800)
• CAS Latency 18
• Timing 18-22-22-42
• Voltage 1.35V
• BIOS/Performance Profile Intel XMP 2.0
• Features Designed for high-performance overclocking
• VENGEANCE LPX is optimized and compatibility tested for the latest Intel DDR4 motherboards and offers higher frequencies, greater bandwidth, and lower power consumption.
• Recommend Use AMD 400 Series / AMD X570 / Intel Z390

Could be an issue with the MCU?
Does the system POST and perform as expected in single channel with D.O.C.P enabled?

 

Thanks, tried this...but to no avail. Pulled out one stick (so was running just a single one), but the D.O.C.P. setting still fails the POST. Have to reset bios to default to get it to boot to Windows.

 

I would guess then that the latest 305 BIOS you have installed has not yet proven its compatible stability, perhaps with a HW driver or the likes. Others report laggy system performance even with 3.4, however everything returned back to normal with a rollback to 3.3
Worth a shot?

 

Solution!


So after a lot of buying/returning RAM sticks, I finally found a solution and everything works great.


Two things I learned (if anyone else needs help with this in the future)...

1. You can't always buy any RAM sticks, just because they will fit/run on your system (if you're looking to get the full speed/compatibility from you system). While most sticks are plug and play, and will load into Windows fine, only the ones specifically recommended to play nice with your motherboard will work fully.
2. Only by purchasing the pre-approved RAM sticks, and not trying to combine slots (IE: I was not able to double up and max out my capacity via two ports, I had to keep them spread out across all four slots), did that fix the D.O.C.P. lock up problem in BIOS. This is probably a quirk of this specific motherboard. Everything is humming beautifully now. So more research is needed, if you want to max out performance (if that kinda thing is important to you).

Thanks for the help!
