Couple of questions -
1- Are you Hex editing or using Polaris Bios Editor?
2- How many watts are you pulling at the wall (no one cares about the 0.85v because it doesn't mean much)
3- What changes did you make to the latency, was it tRCD, tRCDW, tRC, tWTR .......etc?
Thanks
1 - Hex.
2- 5xrx480 = 670 watts from wall, measured with a device, psu EVGA 850G2, 240v, efficiency should be close to 92%.
3- I'm not going into specifics, I just loosed strict timings.
Hynix memory modules are much easier than Elpida concerning making a workable stable custom timings.
Well, the bottom line is, being limited by own choice at 0.85 memory and gpu core clock and yet trying to get the best of a product is challenging, in theory it might, testing shows a balance in execution.
Off topic: I returned from a long trip and looks like I received many private messages asking if I have roms for sale, I will say here the same thing I said to them, "I do not sell or distribute roms, my work is for scientific purposes, I hope you understand it.".
