Woke up this morning to majority of my shares being rejected.
I'm assuming this was because memory was set so high (1900 mhz) I pulled it down to 1850 (925) to see if this helps.
What GPU do you have?
Invalid shares are usually due to invalid timings on gpus , if you get them after modification.
I recorded a video with the process, and when I reopen the rom with the modified straps, they are the same as those in estock rom, do you know what the problem is?

When you reopen , it shows edited timings but when you click on it it shows previous timing. But the saved file contains actually your edited timings. Tried this myself and replicated your problem. Did you upload edited timings to your gpu. 2nd set of timings was for me that increased performance significantly.
