sorry, i don't sugar coat. that single stick of ram is making things worst. i do know that apu crossfires with a HD6000 series card not sure exactly which. if you want to stick to amd i recommend the FX6300 (no less) and am3+ board. make better use of the 7950.

lol. no prolem mate. at least now i know whats holding the gpu back. thanks a million.

btw, any recommendation on which ram should i purchase or i have to buy another stick of kingston ram? i know it have to be identical.

anyway, is this it? http://www.amazon.co.uk/AMD-FX6300-Edition-4-1GHz-Socket/dp/B009O7YORK

which one is better? i5 3570 k or the one you recommended.

yes, if going intel that i5 will be perfect. have you checked the haswell - i5 4670K?

edit: yes, try to get an identical ram.

yeah, i was thinking to get that too. but too pricey in my area and i heard the haswell doesnt improve much from ivy. is it true?

i mean in gaming.

Is it possible to unlock R9 280X vram voltage using VBE tool or in some other way?
post #767 of 1284
can anyone please help me out with this bios? i tried multiple bioses and modifiying the bios myself with no success.

i have three sapphire 7950 and my hashrate is good but i draw from the wall around 1000 watts.

i tried to use VBE7 to decrease the voltage and the gpu just gets stuck until i flash back the original bios.

here are the stats of my gpu.



my current bios is below 015.040.000.001.000

if anyone has any idea on where i can find an answer pls let me know.

Can you decrease the voltage with software tools?
If not, you have a not supportet voltage controller.

If your BIOS is not working with even sligtly voltage changes, your voltage controller is not adjustable.

Than you can try to change it with VBE7 to a suportet voltage of 0,95V.
If your ASIC Quality is not too low, 0,95V should be fine for 950MHz.

Maybe it's better to change the voltage with a HEX editor in your Powerplay states: 01 FF and 02 FF to B6 03.

this GPU is voltage locked and i couldn't modify it.
my asic quality on this GPU is around 63%.

i thought that VBE would do the same job as with the hex editor that's why i didn't venture there and the dreaded hex...

thank you for your input i guess i have no choice but to edit using the hex file.

i read online that this bios version was actually for the 280x, could it be?

i am not sure what you mean by "in your Powerplay states: 01 FF and 02 FF to B6 03" but i'll check it later.

  1. 1.) Kahboom tweaked the memory timings of a bios I'm using, with the memory clocks set at 1500mhz. Does this mean that 1500mhz is the absolute best clock speed to use, or would I get better performance at 1675mhz? (which is what I've overclocked mem clocks to before)
  2. 2.) What's the difference between the clock numbers (1,2,3,0)? #1 looks like 2D, #2 looks like UVD, but I don't get what the difference is between #3 and #0 -- are they both 3D? I thought there should only be one 3D clock.
