These sticks could not reach the 3600Mt they are rated for. Even with timing and voltage adjustments, they could not achieve speeds even nearing the advertised speeds. The faulty sticks were replaced with better sticks that immediately worked at 3600 with no adjustments to voltages or timings. If one stick were bad, that would be understandable. But the fact that none of the four sticks were able to achieve the rates speeds suggests more than poor quality control, it suggests ill intent.

Please make sure you check your motherboard maker's memory/RAM compatability list. This is not compatible with the MSI X570 Meg Ace - I had to alter the DRAM and SOC voltage. Do not assume that because G.Skill advertises this as being for x570/Ryzen 3000 that it will be compatible with your board. My fault for not looking at the QVL. I'm still giving it 5 eggs because it worked great after I messed around with the BIOS. Note this is on the Asus ROG Crosshair VIII Hero QVL. I will likely return to go with something that is more compatible OOTB.

3 Times in my life I purchased high-end Corsair RAM, their top of the top, my last kit was 64GB of their Corsair Dominator Platinum RGB with Capelix LEDs that cost me with Import tax and shipping 755USD. Every time i shipped the kits back to seller, they NEVER worked at XMP speed, the last kit only worked at default speeds or 3000Mhz tops, on top of all it came with one RGB dead and the same day another RGB burned LOL. I only had two expensive G.skill kits so far and they both worked as advertised, when i contacted their CS support i got fast replay [waited for 4 days for corsair to replay]. G.Skill is the only professional RAM manufacturer i met so far: They test their kits with as much motherboards as possible and all the information is available easy on their web ... More3 Times in my life I purchased high-end Corsair RAM, their top of the top, my last kit was 64GB of their Corsair Dominator Platinum RGB with Capelix LEDs that cost me with Import tax and shipping 755USD.

From now on i wont even look at otehr manufacturers since i burned myself and learned a lesson, G.Skill #1!
