    Its an old cheap Sempron. Now you motivated me to try 1 card with Intel CPU.

    Yeah thats probably why. I got a rig with that CPU also, the GPU load is never 100% and its always slightly slower. Not much you can do really.

    Maybe try unlocking the 2nd core, however it didn't work for me.

    Indeed I got few more hashes running the miner with my i5 Smiley

    Anyone here tried any of my roms with the XMR miner? Seems its getting more and more popular since ZEC mining profitability is down the drain.

    I have a few very low quality Samsung memory RX 470 and they don't work with lowered timings, but those roms are really amazing! Thank you for grouping all that material together, you made our life simpler

    stable zec mining with my 280x:
    gpu 1070
    mem 1500
    vddc 1.094

    217 h/s
    155W at wall

    280x consume a lot of energy. I have few of them and I'm trying to sell it.

    7970/280x modified bios gets around 610h/s with XMR Claymore miner.

    Doesn't really help since profitability for the day is exactly like ZEC, however much less power usuage.

    Most of it was already done.

    Saved with vbe to 1020/1500 at vddc 1163

    Only one strap needed to be changed to be same as recommended changes in thread: https://bt.irlbtc.com/view/1676474.0

    here it is: http://www.filedropper.com/280xsapphiremodded

    you have the following memory timings:

    400
    800
    1500
    200
    800
    1500
    400
    800
    1500

    Your BIOS has 3 different types of memory as indicated by the 7th character from the left of each string, (1, 2, 3)

    So you want to modify the third, sixth, and last string AFTER that 7th character, unless you know which type of memory you have and you know that it is only the one designated by the 7th character.

    Normally, there would be a timing before the 1500 string that was a little closer in speed, like a 1250 or 1375, so my best GUESS would be to copy the 800 string AFTER the 7th character over the 1500 strings for each of the three memory types.

    Clear as mud, right?

    Out of curiosity, what is the brand of the GPU?  Do you have a link to the original BIOS on the https://www.techpowerup.com/vgabios/ page?

    I have that same card but only with BFR memory, so my advice is a guess, but yes, what you wrote is what I would try first.  Keep in mind that it is a risk. My advice has no guarantee and you might brick your card.  Since that card has no second BIOS, it is a risk that you have to decide upon.  I personally would try it, but then again I know how to jumper a BIOS physically and boot into program mode and reset it using a USB windows 98 boot to DOS.  Good luck.

    tried the 290 rom today and it would crash all instances within 5min unless I used the highest voltage rom and even then gains were not discernible against stilts good old minus .25 mining rom..

    was worth a shot, do you have anything for the ghost 7970 philip is trying to sell in the classifieds?

    I believe that all BIOSes for XFX 7970 and 280x are programmed for both Hynix and Elpida memory.  It should be quite easy to make the strap changes for it's BIOS as well.  Of course, rather than just downloading any old XFX ROM, I prefer to download the BIOS from the actual card and then modify it.  I have achieved results of around 25% increase h/s for XMR that way using the advice in this thread.
