2070S VRAM Overclocking

[Carl Johnson W16]

I have a Gigabyte 2070S Windforce OC 3X with Micron GDDR6 and i want to push the card to its limit thanks to not being able to secure any of the RTX 3000 cards (or as Linus said, "F U Miners!").

So far i've been able to push the VRAM to 8001 MHz, thats 16 Gbps effective. I want to test further values like 8200 but on the other hand i also dont want to damage the card as i read about Micron GDDR6 generally doesnt like more than +1000, which is the current value.

Temperature wise its perfectly fine, in stock values it doesnt exceed 65 degrees and to be safe i fixed the fan speed at 55% which is more than the stock setting (45-50%).

No sound or PSU issues, have a HD700 with 4 PCI connectors split between two cables and one from each cable is plugged in. Card has 8+6 connector.

Any suggestions?

That sounds like a pretty robust memory overclock already, time to work on the core OC?

The best way I have found to test vram oc is to run heaven as a load and watch temps with hwinfo. Increase the speed until performance starts decreasing or becomes unstable. Then back it off by about 50mhz and run through other tools and games to make sure its good.

Yeah im just wondering if i can get more than 8, not started on the core yet but i dont think i will get too high there because its already have a good factory overclock and in the high core clocks it has a bit coil whine. 1815 is the factory value, GXT and GZT are 1800 and ROG is 1915. 

Im thinking about dialing in 2GHz and checking the CW without having to deal with the voltages and stuff but before that i want to get the memory done.
