But i also have 2x 7950's, wich after i read this thread, i also wanted to mod the timings on, this is how i ended up with the hex editor.

Yep, I think there are no editors for Tahiti cards, so hex is probably the way to go.

I found a topic on some forum where someone explains hows to do it, im gonna try it tomorrow, aftwer that ill do my rx460, it only does 320h/s on cryptonight and i see people in this topic reporting 500 hash.

Well, I don't think there's a lot of people out there hashing at 500 H/s with their 460/560 cards. It's certainly possible, but requires very good memory/timings, or serious overclocking. I've only built a couple rigs with these cards so far, and didn't do any fine-tuning, so could probably improve my results at the moment my cards are hashing at ~ 420-425 H/s, all running at 1100/1750@0.875V. Cryptonight profits have gone down quite a lot, so I guess I'll be switching to ETH soon (where they do ~ 13 MH/s each).

Was it this type H5GC8H24MJ? What timings are you using? Would you test my XMR timing for that?

I have this Memory on a AERO ITX 560 4G SK Hynix H5GQ8H24MJR
still testing but so far:
OC: CORE 1167 DPM 3 V925 MEM 2200 (I Have to set 925 for stability but an other card seems to be stable with 900)

Hash: 473H/s on Cryptonight ~ 28W on amd-info (use HiveOS) All machine (CPU/USB key/...) Less than 82W
Hash: 15.5MH/s on Ethash ~36W on amd-info All machine Less than 93W

Those are some nice numbers, i finally figured out how to edit the bios straps for my 7950's, and i did it, but tbh i dont notice much more hash/s.
i bios edited 2 saphire 7950's and the 3rd 7950, a club3d 7950 wich i didnt mod yet, actually does more hash.
2morrow im gonna try to biosmod my rx460
