Bether to buy 970 cards. More hash, bether density

Performance rough numbers with the new miner(x11) build 21

980 9500 KHASH (+-500KHASH
970 7500 KHASH (+-500KHASH)
780ti 6100 KHASH (+-500 KHASH)
750ti  2850 KHASH (+-200KHASH)

I testet build 21 on the 650TI yesterday and it was able to find shares. (quark). Compute 3.0 is probobly fixed for most algos now.

960 is coming also, it seeems a good card for the price, but the sweet spot will probably remain with the 90


i have Smiley

been running for 30mins at the moment with the 6 x gigabyte 70ti oc cards ... stock clocks under linux ( fedora 19 x64 ) except for -i 20.5 ...

results below ( about 30 seconds ago ) ...

running nice Wink

anyone know to oc these cards under linux?

tanx ...

If you have the gigabyte windforce edition (with a 6pin powerconnector) you can upgrade the bios to Windforce Black. Should do 3MHASH on standard clocks under linux. (The upgraded bios will not work on Windows)

i have 11 of those ones - about to purchase quite a number of the low profile ones ( without the 6pin power socket ) same performance but no firmware upgrade ...

i might test that soon actually - have a look into it - but i doubt if it would be viable to do so as they will lose resale value if they are to stop working with windows ...

tanx for the heads up though ...

750ti are a waste of space and hardware, for every 2.5 rigs you could have 1 rig that do the same hashing 970 and 3:1 with 980

not if i dont want to pop my power circuit on a regular level ...

the 750ti oc is powerless now ( low profile edition ) AND only around the $170AUD mark which uses one 875W PSU ... as opposed to the GTX970 which requires two power connectors ( 6 pin and 8 pin ) which means you need 2 x 875W PSU running in tandem ( or a large 1200-1500W - which escalates the price dramatically )  if you want more than 4 cards in a single machine and it costs around the $540AUD mark ... which means more cost per machine and a higher $/hash ratio ...

no doubt that the GTX 970 is one hell of a gutsy card - but the cost of the machines to build becomes almost ridiculous ...

either way - i have tested the non-powered ( no power connector to the card ) low profile 750ti and am getting some nice hashrates ( approx 2700-2750) at approx 60W per card ... Smiley

this power consumption and the price that they are at the moment - make them the better value card for a stock build ... if you OC and play with the BIOS ( if you have the windforce edition as sp_ was mentioning ) it gets even better value ...
