The card already is hitting 70deg on open rig...
Perhaps after I find time to change the paste...

70deg is normal. Cold actually.

Hello,

I installed this Mod Bios on my MSI R9 380 4GB and hashrate now is 24 MHS stable. With 980/1650. I noticed that core clock does not change anything, Even if i put 1100 or 880, no difference, only mclock change things.

Thank you Ralph!

You cant change mem timing with tongabiosreader, you must do it in hex editor, just google it.

I have one of those - it SUCKS. Somehow, even with *custom* timings, not a copied strap, it STILL sucks ass.

You're starting to surprise me..

I think i missjudged you..   Wink

You do have a history of letting your ego cloud your judgment.  :-)
Remember the bitcanuck R9 380 thread in the ethereum forums?  You were convinced that reducing the core clock would reduce eth hashrates, but you were wrong.
I can't find the thread any more, as I think one of the mods deleted it.  I could probably find it with the wayback machine if you've "forgotten" it. :-)
Come to think of it, you're a mod on the ethereum forums, aren't you...


It was in this thread, while I didn't realize it at the time, this remarkable counterintuiative result was published by (Helox?/Bitcanuk?/dihenky?) for the R9 380 which was an R9 380 stock at 800-820/1500 was hashing at 20+ MH/s. These spec's also result in the card's lowest power consumption @ 20+ MH/s.

The results in this R9 380 hot rodding thread are somewhat incomplete in that corresponding changes in power draw with mod's would also be of interest.

just modified it myself with a hex editor, copied straps.
r9 380 2gb strix can go even higher than 24 mh/s

I don't really understand what straps are. I did find information about changing straps on the forum before for another cards, but did not understand them very well. I will do my best to understand how to do it. Sorry that I disturbed you.

Copied strap didn't work on this one, almost. It went up, but not by much. Custom timings had an effect, but again, it still sucked for me. Maybe I just got the short straw on GDDR5 chips in it.
