Can Claymore or someone else explain why the recommended variable for GPU_FORCE_64BIT_PTR was changed from 0 to 1 for this miner?

Of course... But it depends on what card you have since some need core overclock and some need memory overclock to increase hashrate.

Quote from: miner63456 on June 20, 2017, 02:25:18 AM The 2 GB problem can be solved with a certain memory management scheme. Level of effort may not be worth it, but Claymore can PM me to discuss. We're talking about literally millions of dollars at stake here. I don't think any level of effort would be too much.

He does have 3GB, but you can't mine ETH anymore with Tahiti cards. Just mine ZEC, almost 300H/s per core. I'm mining with a Tahiti card right now? Hashrate is low, but it works.

Quote from: ne0x86 on June 09, 2017, 05:29:49 AM Hi guys, I just trying to mining dual eth+sc with my gtx 1060 and I got about 20 mh/s and 130mh/s. Eth mining speed is normal, but is SC speed normal? I think its very low, whattomine say 990 mh/s Thanks You won't get full mining speed for the second coin when dual mining. If you want full SC speed, use a solominer. That said, you can maximize your efficiency by playing with the -/+ keys in the runtime which will change your -dcri value. Hit "S" for stats and you can find your best ratio.

Quote from: notbatman on June 06, 2017, 11:45:21 PM Quote from: vogonpoetry on June 06, 2017, 10:18:28 PM Thats pretty low for Sia. I've got a 7970 and it gets 12.5MH/s ETH plus 620MH/s Sia. You probably want to add the -dcri xx argument I have mine set at -dcri 49 and it gives me double the Sia while only lowing ETH by like 0.5 MH. You can tweak the -dcri value in the runtime using the +/- keys. Then hit "S" for stats and you can find your best ratio. Then put that in the start bat. Try UBQ, MUSIC or EXP you'll get 25 MH/s due to the smaller DAG, I'd also go easy on the SC with these older cards. I underclock mine and run the fan at 100% BTW. So I redid the thermal paste on my 7970 and temps dropped >20C! Went from 90C at 100% fanspeed to 69C at 67% fanspeed dual mining ETH+SC. The previous owner slathered on way too much paste and didnt tighten the cooler down enough either. Runs like a dream now.

Well I'm just using the 7970 as supplementary to my main R9 390 which gets a nice 31MH. Pulling >43MH on two old cards is not bad at all, IMO. As for the SC, yeah dual mining really heats it up. Hitting 91C in a cool room, but I need to replace the thermal paste. Not even going to attempt dual mining on the 390. That thing is already a furnace. I turned it on once and it hit 94C pretty quick. You think mining one of those coins would be more profitable on the 7970 than ETH+SC? It's gonna take forever to hit the payout in the Sia pool at this rate.

Quote from: tbly13 on June 06, 2017, 05:52:10 PM Just looking for some opinions here: I fired up 2 AMD 7950's Dual-Mining ETH and Sia Last night. Been sort of tweaking the settings and Overclock over the past 12H but wanted to see if I am getting proper results for my settings: BAT: setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100 EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0x9C242ad2B0cF40f58e01C7b8c3b79f83F792bD18 -dpool "http://siamining.com:9980/miner/header? address=be71aa6e9ca5e046fde5c6fedc9a295bbf631acd300b57d7e20559bd53850f3d86442bc20ee8&worker=Work1" -dcoin sia CLOCKS: AMD 7950: 1050/1500 Haven't done much OC tweaking/testing with these - Just raised memory clocks mostly to see a little MH boost MH: Client Side - ETH: ~25MH (Accepting around 20-25 Valid Shares/hour on ethpool). Sia: ~385MH (75-80k Valid Shares/Hr on SiaMining) Pool Side Screenshots- ETH: https://www.screencast.com/t/ySMnJBLuwE , SIA: https://www.screencast.com/t/qZyq9wv9 Wondering if these results seem normal, or if I could be doing something better? Thanks! Thats pretty low for Sia. I've got a 7970 and it gets 12.5MH/s ETH plus 620MH/s Sia.

Quote from: dazz on June 02, 2017, 09:41:52 PM It's been a while since I last mined ETH+DCR or SIA. Can someone let me know what's the current normal hashrate for HD7970's please? Now mining at miningpoolhub, ETH+SIA, dcri 90, I get some 12Mh/s in ETH and 550MH/s in SIA. That's with Crimson 17 drivers, pixel patched Thanks I'm having the same problem. By all accounts, this card should be mining at ~20-22MH/s but I'm only getting 12.5 no matter what I do. I've tried both the latest drivers and 15.12. Pixel Clock Patcher did nothing. Edit: After some research, it seems like this rate is par for the course for the 7970/280x due to the current DAG size slowing it down. Bummer. Seems like other coins are the only answer. Though I might just use mine to dual mine. 12.5 is better than nothing.
