I've stopped following NV a couple of years ago so take it with some salt...
As far as I've understood, the ALU-to-memory resource ratios in small maxwell are much more appropriate to efficient memory usage. Approximated: there are more "memory ports" compared to ALU count. What could be happening is that big GPUs ALUs are tripping on each other. Very approximated: every ALU has "more chance" to get to memory. It is also possible to reproduce this on GCN1.0 (which has quite smaller buffers BTW).
Try measure the amount of memory effectively moved. I'd expect it to be much bigger for big maxwell and in both cases far higher than it should.
As a side note: "memory load" is unlikely to be what you think it is. It's most likely "memory controller active"; it could be active but stalled (~ shut down but burning energy).

RELEASE 1.53-- I get 10.45Mh/s on my GTX 960 SSC mining quark. This is with the intensity at 24, and an overclock of +80/240, core/mem. Intensities of 24.1 or higher fail on launch, and most often crash the driver. I was getting 10.6Mh/s with -i 23.7, and OC of +100/300, core/mem, but it became unstable in the last few versions. The Lyra2 perfomance really puzzles me, though. It should run faster than a 750ti. --scryptr
you should monitor FB usage (Frame Buffer) with msi ab, if it is too high, then you should decrease the intensity. A rule of thumb for the intensity is to get it to 99~100% gpu usage (starting with lower value obviously) and stops when you reach 99% there is no point in pushing it higher. Some progress with neoscrypt: 750ti: 186kh/s (was 150~160) 780ti: 430kh/s (was ~350) 980 735kh/s (was ~650) sp-mod 53 is doing 190Kh/s on the 750 (non ti) with overclocking. my blake rewrite added 15-20KHASH from your first public version.

(1.5.50) and incorporate that changes already, so whatever is the original speed this one does 30kh/s more

2 sp_ Tried your #49 with neoscrypt I tried djm's version before and for my poor gtx 750 1gb it runs only with -F 1 and gives 175khs. Default run with your #49 start /realtime ccminer.exe --cpu-priority 5 -a neoscrypt it takes almost all gpu memory and pushes load to "Bus interface" as it called in GPU-Z. With such conditions performance is poor - only 45 khs. But i tried to play with -i parameter and found that it runs with maximum -i 14.5 With such config it shows 810MB memory usage, 0% bus interface load, 99% gpu load, 30-35% memory controller load. The numbers are 187khs and this is better then old djm's version. But i didn't check on the pool yet . So I think you should use not so heavy default launch config for this algo for low-level gpu's like mine. Could you try release 53 please. Is perfomance lost?

Another thing, in mining Lyra2 my GTX 960 cards mine more slowly than a 750ti. I don't understand it. I think there may have been another post on this 10-20 pages back, but this thread is getting long. --scryptr It seems lyra2 is memory bound. Unless the 960 has more memory I wouldn't expect a big increase, but I wouldn't expect a decrease either. Try to reduce the intensity with the -i parameter. I think the 960 is using the same default intensities as on the 970 and the 980 wich is too high.

but the speed should be higher than 150-160 on default clocks try with -i 14.5. (windows x86 builds)

I miss a lot my ccminer times, now electricity is so expensive here in Brazil, tks to corrupted politicians and a crazy government My 980s and 970 now are set only to run games sporadically.

Mining is more profitable than ever if you know what to mine. 3x 980 and 1x 970 will give you around 75MHASH of quark. (sp-mod 53 light overclock) Around (0,04BTC per day) (10USD per day) should be enough to cover your bills. I expect the power usage of your rig to be around 700W? then you use 16,8 KWATTh per day If your power cost is over $0.59 per KWh, you loose money.. Normally in other countries (your competition) the powercost is around $0.05-0.20 per KWh

Interesting, Quark is placed at 35th on the market, costing about 2k satoshis each...with 10 USD/day I get a good profit (about 140 USD/month), but there are electricity penalties for those who "abuse" of it here, it´s called red flag state, it is a pitty. Cheers

Cheers not only quark the coin, but quark the algo.. Google sharkcoin, dimecoin,securecoin etc. Alot of profitable coins. or just mine at nicehash. They pay around 0.45BTC per GHASH now..

85GHASH on westhash+nicehash combined. This is 42500 radeon 280x gpu's using the opensource sgminer. on around 15000 750ti's with the sp-mod

0.29 right now. What the hell is happening with quark coins? Time to investigate... Here are a few quark coins with how much BTC worth of coins are getting mined each day with current prices: BitQuark (BTQ) ~0.01 BTC; MonetaryUnit (MUE) ~0.031 BTC; QuarkCoin (QRK) ~0.057 BTC; Dimecoin (DIME) ~0.11 BTC; SecureCoin (SRC) ~1.51 BTC; SharkCoin (SAK) ~65 BTC. Sharkcoin started blowing up since early May, its price increased close to 10x and now the nethashrate is around 120-150 gh/s. Make of the numbers what you will. Ps: I feel like I forgot at least one relevant coin but can't figure out which.

But when the gpu's are moved to the quark algorithm, other algos get a boost in the payout. x11 is 2x more profitable now than 6 months ago. lyra2re is 3x more profitable than 6 months ago etc..
The 150GHASH is comming from somewhere.. People move their rigs to mine the most profitable.. 6 months ago quark clones had a global net hash of around 10GHASH and the payout was close to 1 btc/GHASH before the multipools/rental sites got it down..

They seem way off compared with a week ago on yaamp and what is currently reported on miningpoolhub (SRC .32, QRK .22). And I have no idea about SAK except that I can't find anywhere to trade it.

The numbers are blocks per day * block reward * price. So the numbers represent the whole pie that's being distributed to all miners each day. You could throw infinite gh/s at BitQuark for example, you'd still only earn ~0.01 BTC a day. http://coinmarketcap.com/currencies/sharkcoin/#markets
