So I know I have a ways to go, but I spent last night going through this thread and a few articles on other pages off of this thread. I know this thread was created to help people understand so that is what I am trying to do, i am not hear to ask others to create my values. Few questions to start off. So understanding some of the posts it seems tightening the timings is more memory specific than card specific. So I can create a value from a rx 480 sapphire with hynix and it could work on a gigabyte rx480 with hynix?

Yes, for instance a 4GB memory strap for hynix will work across brands like Sapphire, HIS, MSI as long as the card has the same 4GB hynix chips for memory.

When looking at timings for 4gb vs 8gb, changes can be made in different places. For example on my xfx rx 480 8gb with samsung I see only samsung timings but in my sapphire rx480 nitro+ 4gb, I see places I can change for either samsung, or elpida/hynix.

Most 570 cards come with multiple timing sets even though they have only one kind of memory. In such cases, only mod the timing set that is relevent to the kind of momory the card is using (identifying what the memory is by looking at the stock strap comes with xexperience)

I am using srbpolaris / polaris and even with my 570 I see changes on 4gb cards being made at the 2: section for elpida/hynix vs 1: for samsung. I know that is just strap copying, but gotta start at basics. In srbpolaris (I know most of you guru's use linux, and it is not my forte, but will work on learning) I am able to analyze a strap and I am seeing alot of sections I can change. After reading some more through the thread, I see that it is not always a specific set of values for every card you can change, seems I need to learn the cheat sheet for what each value does. It seems FAW is one that can always be set to 0 but I dont see 32AW (at leasnt not in srbpolaris). TRP can be changed it seems pretty consistently throughout all cards? Also I am unsure how to decode the MISC. I could be using the wrong tool, and if so I just need to spend more time on what else I can use. Any guidance you all can provide would be really helpful and appreciated.

Use nerdraplhs tool linked earlier in this thread, he posted it as a simple weblink that you can easily access.

So I tried nerdralphs tool and seemed to work ok. Something I am confused about is how can I change the voltage offset in the rom. For example I am testing with my xfx triple x 8gb card. I took the 1750 and 2000 straps and put them in his tool and copied the new value in polaris. Now when i start up the miner and open watttool I can set the voltage offset in windows watttool to -18 and shave about 40 watts. I am unsure how to set this in the bios because I cant find an equal tool for linux to set the voltage offset. I came across a few threads talking about I2C but I dont fully understand where that is and how I can change it to stick in the bios.
