I just finished overclocking my standard 6000 cl30 A-die kit to 7800.
I didnt think this would go so easy because after all higher speed kits are way more expensive (especially now) but here we are.
I already spent some time with the 6000 setup before so i know roughly what this kit can do in terms of timings.
8000 might work aswell, havent really tried that yet. But my board only officially supports up to DDR5 7600 so this might very well be the limit.
What i found was that its almost completely up to Vddq/Vddio voltages to actually stabilize that speed on my motherboard/imc. There seems to be a range of 40-50mV which is somewhat stable or not even booting every time to ACTUALLY being stable. Needed some time to find that spot and it seems to be 1.4V with my mobo (B650 Tomahawk)
1.38Vddq/io didnt work and 1.42Vddq/io also wasnt quiet stable. 1.4 IS. 1.45vddq/io is definetly also not stable.
Just want to post this to show what a standard 6000 cl30 kit does. Lol
And its even justat 1.45V which is an expo voltage. Its entirely possible that with 1.5Vdd it does 7800 cl36 with even a bit tighter primaries and easily does 8000 cl38 at 1.475 Vdd at most.
