Here's what I got with your new Windows 64 miner, all GPU voltages at 1.2, I used Sapphire HD 7970s (Hynix), and your recommended configuration:

@echo off

setx GPU_MAX_ALLOC_PERCENT 100

setx GPU_USE_SYNC_OBJECTS 1

nsgminer 2>logfile.txt --neoscrypt -g 1 -w 128 -I 16 --gpu-engine 1000 --gpu-memclock 1500 -o

stratum+tcp://neoscrypt.usa.nicehash.com:3341 -O [ADDRESS]:[x]

I rebooted the rig between each test and deleted the existing .bin file. I didn't use any type of driver cleaner utility.

I achieved the following after 5 minutes of mining from various AMD drivers when placed in your miner's folder:

Okay, so that was for a rig of 4 HD 7970s, all Hynix memory. Next I tested the 14.9 drivers on

4 Gigabyte Windforce R9 280x GPUs, all Elpida. They wouldn't start with I 16, so I bumped them

down to I 15.

AMD 14.9 at I=15:

[09:36:18] OCL0 | 5s: 0.0 avg:374.0 u:284.6 KH/s | A:22 R:0 HW:0 WU:16.3/m

[09:36:18] OCL1 | 5s:361.6 avg:374.9 u:271.7 KH/s | A:21 R:0 HW:0 WU:15.5/m

[09:36:18] OCL2 | 5s:361.7 avg:374.0 u:323.5 KH/s | A:25 R:0 HW:0 WU:18.5/m

[09:36:18] OCL3 | 5s:361.4 avg:373.9 u:258.8 KH/s | A:20 R:0 HW:0 WU:14.8/m

That looks like comparable output for Hynix memory but at lower intensity.

==============================================================================

Now I will test Wolf0's neoscrypt.cl and .bin from the most recent Nicehash miner bin folder with sgminer-5-0-1, xI=2. gpu-threads=2, 1000/1500:

280x Elpida, with Wolf0's neoscrypt kernel with AMD 14.7rc3 drivers I get:

[09:53:00] GPU0 | (5s):403.8K (avg):

**424.4**Kh/s | A:2496 R:0 HW:0 WU:403.230/m

[09:53:00] GPU1 | (5s):406.7K (avg):

**426.6**Kh/s | A:2432 R:0 HW:0 WU:399.363/m

[09:53:00] GPU2 | (5s):406.3K (avg):

**425.7**Kh/s | A:1728 R:0 HW:0 WU:253.722/m

[09:53:00] GPU3 | (5s):405.3K (avg):

**425.6**Kh/s | A:2048 R:0 HW:0 WU:331.606/m

And going back to the HD7970 cards with 14.7rc3 drivers I get:

[09:57:30] GPU0 | (5s):407.0K (avg):

**417.7**Kh/s | A:2368 R:0 HW:0 WU:373.366/m

[09:57:30] GPU1 | (5s):408.4K (avg):

**419.9**Kh/s | A:2368 R:0 HW:0 WU:380.408/m

[09:57:30] GPU2 | (5s):410.5K (avg):

**419.4**Kh/s | A:1856 R:0 HW:0 WU:291.159/m

[09:57:30] GPU3 | (5s):406.9K (avg):

**416.4**Kh/s | A:2368 R:0 HW:0 WU:387.625/m

So, in summary, from the perspective of this dead-end user, it seems that for the moment Wolf0's kernel and .bin file from the most recent Nicehash miner bin folder and AMD 14.7rc3 drivers has the better hashrate.

Also, I cannot explain the apparent discrepancy in sgminer's accepted as compared to nsgminer's accepted. I assume that there is a factor of 100 somewhere.
