Here is the deal gtx970 with the new buff 21 mhs 150 watt 0.14 mhs/watt ebay 250$ http://cryptomining-blog.com/7341-how-to-squeeze-some-extra-performance-mining-ethereum-on-nvidia/
r9 280x 22 mhs 230 watt with the 169 $. 0.09 mhs/watt
i realy intrested gtx 980 performance with ~170watt
in this case nvidia actualy more than worth than amd card.
what is your oppinion?
i realy intrested gtx 980 performance with ~170watt

    First of all, don't quote ebay prices as lot of the stuff on there is abused or refurbished, damaged junk or the seller will try to scam you. So that's off. Let's talk online ordering of new products or local stores (in the USA at least).

    NVidia even with that tweak/mod might use a bit less power, but not worth it due to the costs. Period. A GTX970 will run you $300 minimum, averaging about $340.
    An R9-280x by the way can be tweaked also to reduce power by 10-20% and it still gets 21-22MH/s and costs about $240 new.
    An R9-380x should yield about 23-24Mh stock, can also be tweaked for more speed or less power and costs about $240 new also.
    An R9-390 uses stock about 210watts and I tweaked it down to about 190W each and still get 29+Mh per miner. Costs $340 average.

    Heck you can also buy 2x R7-370's and get about 33-34MH at stock speeds, using 300watts combined (a bit less actually) for a total of $250 if you can spare the extra slot used in the mining rig and save even more. I'd buy an R7-370 over a GTX970 at 1/2 price any day..

    ok r9 280x short term totaly worth if you using for mining more than 2 years with nvdia sum profit is bigger but i don1t think mining 2 year with the same card is worth.

    I am running win 7 with 2x XFX R9 280x, I installed the crimson 15 aka catalyst and I installed the amd dev kit v 2.9, I am avg 41 Mh/s with both cards
    I wanted to know how to tweak these cards knowing that I am using a kill a watt and my reading 560 including that squre fan with almost 100 watts, with my gpus not connecting to a monitor I can't read the temperature as well as i do not have any interface to interact with each time i try to use the catalyst it says i have no compatible driver yet i am still mining https://ethereumpool.co/stats/miner/index.php?address=0x4891086939115c7c72fa02124361a809133e5042#
    but still don't know how to squeeze the best performance out of these cards and thanks

    Alot of misinformation in this post....

    For one thing there's nothing wrong with eBay I bought 80 percent of my mining hardware from there, sellers like newegg bestbuy target etc sell brand new hardware on eBay and I've bought a ton of used cards there as well all were flawless

    Secondly I have a bunch of 380x and 380s and the hash at 20 to 21 Mhs max there's no reason to pick a 380x over a 380 hash rate is the same the use around 170 to 190 watts and you saying you're getting 24 Mhs for a 380x is plain false. No one has seen hash rates that high

    On the 390 I have 10 of them best hash rate is 28.5 Mhs stock and they use close to 300 watts! Nowher near 200 like you claim.

    I don't think know anything about 370s but they seem like a waste of a slot in flu mining since you have a max of six slots per board the goal is to min max hash rate vs power since you need a new board for every six cards. Anything under 18 Mhs is a wasted slot

    Personally I agree with the op, I'm buying refurbished 970s I would gladly trade the higher hash rate of the Amd cards for the lower electricity bill, I'm only grabbing nvidia cards now.

    First problem is the error you get when trying to see the GPU stats through the catalyst driver. Either it's overclocked too high or something else is wrong with the install.

    What box fan are you using with it? That has nothing to do with the power usage of the video cards. The cards themselves should not be using more than 280watts at full blast with no tweaking which seems inline with your results.

    Don't tweak anything until you fix the underlying errors first.

    I suggest you check over your rigs and your tweaks then. All my R9-390's run at just under 200watts at 280+MH, with a slight undervolt. Maybe your 'used' and ebay GPU's are just sheyt or your Power supplies are in-efficient. I only use new retail stuff as I get them very cheap.

    How is it a waste of flu to mine with 6 R7-370's?? U serious? I have lots of motherboards and cpu's so no extra cost there. Same with power supplies. Even if I were to buy it, it's about $120 per rig extra.
    Each R7-370 is about $120 (RETAIL/NEW) so $720. RAM is cheap (8GB for $28).
    So at a cost of UNDER $900, it hashes at around 100MH, earning about $550-600 at current levels per month. Power usage is 150watts per card, so it is a bit less efficient than the R9-390.

    Your numbers are off and I suggest you get better quality parts or re-check your power use and voltage.

    All my power usage is checked with kill-a-watt meters at the wall, using EVGA G2 1000-1300 Power supplies.

    That's the R9-270x. I don't think it's worth the extra $$ vs a normal R7-370 IMO, but I have not tested that card yet as I have not seen it in person.

    You might have lots of space and motherboards PSU's to waste space on a lower end GPUs but most people do not , its all about hash rate per watt.

    Pluse those 370s are 2GB cards, in 3 in four months they will be worthless to mine eth when the DAG crosses 3GB then you have a bunch of worthless hardware as far as eth mining is concerned.

    Better to buy 3GB or 4GB 7950s or 280s and 280x's

    The DAG file has grown by just 300MB in 7 months of mining, at that rate we have another ~14 months to go before the DAG file exceeds 2GB... and we'll probably be PoS before then anyways.

    older mobo/CPU combos with 3-4 PCI-E 1x slots can very inexpensive used, and four 270/370 cards can easily be run on a sub-750w PSU... at maybe 1/3rd the price of a 1300w beast


    I have a pair of 270's that do 36MH combined and use under 280w doing so. Yes, it's 20% slower than a pair of 280X, but the cost per card is also 40% less

    I mean... if I could get hynix memory 7950s in large quantites at reasonable prices, I'd totally do so.... but it all comes down to cost and 7870/270/370 can be obtained cheaply, and the lower power density means far cheaper PSUs

    Plus when ethereum mining is done , the GTX 970s are really good for mining other algorithms with low power usage while the AMD cards become far less valuable and have lower resale as well.

    I expect the difficuly to really ramp up when the price hits $10 or so per ether then you will see a really fast rise in the DAG file.

    Book it.

    That's not how this works, DAG size in the future is rather predictable
    DAG size is based on block height, and Ethereum adjusts difficulty quite rapidly.

    A very rapid hashrate increase results in difficulty ramp up, which acts to maintain block times where they should be, and thus keeps DAG growth rate somewhat consistent

    A bigger issue is likely going to be hashrate drop-off from TLB thrashing

    That's exactly what I m talking about all my 3GB 280x cards have lost around 4mhs of hash rate over time but my 4GB cards have not lost anything which shows me that memory is affected by Dagger Algortithm as time goes on. I don't have any 2GB cards but I suspect they will experience faster hash rate degradation than the 4GB 970s and R9 390s
  • verjicverjic Member Posts: 143
    The processor is important to be powerful so GPU can obtain max Hash Rate? Like in games for example?

    Or I can use any low end Processors like AMD A4 X2 5300, 3400MHz?

    Thank You
  • LogicaluserLogicaluser Member Posts: 214 ✭✭
    I suspect it's something besides the 4GB of memory responsible for the maintaining hashrates as 2GB 380's are still capable of +21MH, perhaps the minor architectural changes from Tahiti to Grenada/Antigua altered the TLB behavior?

    Or... perhaps 380/380x have been held back by the narrower memory bus this whole time, and the impact of DAG growth is just now knocking down 7950s/280x's down to their level

    If you want to experiment, Genoil's recent builds in cudaminer thread include the ability to benchmark at current or future block heights (specify block # after -M )

    Would be interesting to see at what point the 380's begin to drop off vs a 280x
  • Marvell9Marvell9 Member Posts: 593 ✭✭✭
    Yeah I saw that unfortunately his benchmark tool is not acturate since the dag size is not the same from what I heard. Its interested to hear that 2GB 380s are still able to hash at 21 mhs

    I think your second point is more likely then. My big problem with the 380s and 380x cards is their power use though at $200 per card they should not be consuming 180-200 watts like they are according to my PDU.

    the 970s are insane as low as 90 watts per 17mhs but they cost 270 each (used)

    Oh... that's what the adjustable block number is for!

    Yeah, the problem was that the benchmark defaulted to the launch-day 1GB DAG... but using his recent builds you specify current or future block # after the -M for benchmark accurate to that DAG size ( -M 1084668 )

    180-200w at wall sounds about right for 380/380x at typical voltage, even with the narrower memory bus it's still a similar sized core to the 280/280x

    a 270/270x can still do +16MH (more with say... good Hynix memory) at around 110-130w, and are often closer to $100 USD

    Depends on electric costs really, altho at the moment electrical efficiency is of little concern to me, at this profitability I'd rather have the extra hashes

    I just checked my R7-370(2GB) rig. It runs 2x XFX R7-370 DD cards at stock speeds (RAM is at 1500 though) (1050/1500) It is still getting the same hash rate average as last week. 33+-MH/s combined.

    I also tested all my R9-390(8GB) rigs and they all still get 29MH at stock speeds undervolted (50mv). When I run them at the normal 1100/1600 with a 50mv undervolt they get 30-30.5MH still.

    My 'legacy rig' : R9-290(4GB)/280(3GB)/280x(3GB)/R7-370(2GB) rig also still gets the same 88MH+ as last week.

    Not sure what you're all seeing.. Maybe your card mods are not working? Mine are all original BIOS-es, with slight undervolts each. Just using --cl-local-work 256 --cl-global-work 8192*128 with them all.

    Of course, I'm sure my comments will be shrugged off as BS as before... :shrug:
  • LogicaluserLogicaluser Member Posts: 214 ✭✭
    @happytreefriends

    We're talking about the slowdown in hashrates that has occured over the past 7 months of mining as a result of DAG growth, and that will continue over time.

    My best 280X's initially did 26.5mh, but are now closer to 22.5mh at identical settings.
    I had 7950s as high as 25mh each, now more like 21-22mh
    My pair of 270s used to be 39-40mh, now 34mh at best

    Cards with Elpida memory seem to be impacted the most
  • happytreefriendshappytreefriends Member Posts: 537 ✭✭✭
    Ahh yeah, but from that time-span difficulty has gone up what, 100%, so it's pretty much expected. At the same time price has also went up a LOT so profitability is still high.

    Depends on electric costs really, altho at the moment electrical efficiency is of little concern to me, at this profitability I'd rather have the extra hashes

    yeah im thinking more long term , I indent to keep mining something after eth mining is done so I would rather have a bunch of power efficient miners on hand anyways.

    I cant find any 270s for sale anywhere I do see 370s out there in the wild price seems to be around $160

    You can get R7-370s for just around $130 all over the place. Micro Center has them (after rebate) as low as $110.00.

    r9 280x 22 mhs 230 watt with the 169 $. 0.09 mhs/watt
    i realy intrested gtx 980 performance with ~170watt
    in this case nvidia actualy more than worth than amd card.
    what is your oppinion?

    Just do fine tuning.
    All HD 7*** series cards are overvolted by default.
    It's made to deal with low quality power supplies and for overclocking.
    Undervolt your GPU.

    My gigabyte 7970 works 1100/1500 @ 1.057 Vcore and consumes 9.7 A on +12V rail. It's about 120 W.
    Stock cooling, open-air rig, room temp ~ 20 C.

    The processor is important to be powerful so GPU can obtain max Hash Rate? Like in games for example?

    Or I can use any low end Processors like AMD A4 X2 5300, 3400MHz?

    Thank You

    No matter. I saw rigs with 4*7970 and with single-core Sempron 140, undervolted & downclocked to 1Ghz.
    Works fine and no hashrate drop.

    In Windows it matters.
