[Dev] NeoScrypt GPU Miner - Public Beta Test
-
Hi everyone! First real post here. Long time lurker, but finally got around to creating account due to NeoScrypt. So far I am very excited and think this is a great move. I do have some questions though.
Does anyone know if the current settings for solo mining are going to be the same once we fork? If my understanding is correct, we just need to have neoscrypt cgminer running when feathercoin forks and we should be good, right?
-
You can solo mine with the neoscrypt cgminer, but I’ve found that you will need different setting to what you use for Scrypt mining.
The easiest way to try it out now is to set yourself up to attempt solo mining on Phoenix coin to work out your optimum settings and then you just need to change your solo miner setup to point back from the PXC wallet to your Feathercoin one.

Imperialcoin (IPC) is making the switch to neoscrypt in 450 blocks.
Difficulty will be way lower than Phoenixcoin. Maybe use that one for solo mining testing.
My batch files
for p2pool mining : cgminer.exe --neoscrypt -I 14 -w 48 -g 2 -o stratum+tcp://prometheus.phoenixcoin.org:10554 -u -p x
gives 90 kh/s on amd 280x
for local mining : cgminer.exe --neoscrypt -I 13 -w 32 -g 2 -o 127.0.0.1:9554 -u -p
gives about 80 on the wallet

The coin that is switching is IPC, not IMP… https://bitcointalk.org/index.php?topic=476091.0
IMPerialcoin (IMP) is making the switch to neoscrypt in 450 blocks.

Aargh, typo. edited original post
Thanks for correcting me :)
about 250 blocks left before the switch

I just didn’t want people looking for the wrong Imperial coin to experiment with, like I did… :)
Lol, who in their right mind would start a coin with an existing name but use different letters? Wow, thought much not used by IMP devs!!

If your card is older than HD7000 series, don’t bother now. The kernel isn’t vectorised properly for the older cards. I have explained it on the previous page.
See this post.

Please vectorise the HD6000 series… I want to mine PXC :c

Update!
Well I love following this thread. I get all kinds of hints related to what I’m interested in.
The post about IPC starting after 66000 was cool because I figured out after a lot of googleing + stray posts to get the IPC client to solo mine.
I started on the PXC and got some blocks solo mining too. But now back to the blocks factory.
Now I’m waiting for feathercoin to arrive around the 24th.
At this point I’ve got minerd running with my i7 2600k slightly over’d getting 26.3K
My cgminer is running a hd 7750 3gb at 13 K with the -T option because what has come so far doesn’t last the 24 hr test
Best regards,
Raintowers

I like the site idea. But it may also be worth looking at the minerC checkaz is working on as it should make the whole thing simple for everyone. :)

About 1 hour to the IPC switchover, if anyone wants to try out solo mining something neoscrypt with low diffifficulty.

I’m also looking for optimum settings for the 290/290x gpu’s. (maybe a google doc spreadsheet with settings can be developed sort of like the litecoin one?)
Anyway, I’m currently running -I 14 -g 4 -w 32, and have one 290 GPU running 60 kh/s and an identical GPU running 51 kh/s. win7x64, ATI 13.25, 3.7.7b.
Tried another setting shown in this thread
but the 3.7.7b doesnt like the concurrency, and without it, only managed about 45 kh/s.
I’ve configured several rigs now that are running R9 290’s. Elpida based GPU’s run around 100Kh/s, while Hynix ones tend to be around 110Kh/s on 3.7.7b
Here’s what I’ve done on each of them:
Step 1 - Uninstall any 14.X based driver you may already have (or anything higher than 13.12 for that matter). Then grab DDU from guru3d.com and use it to completely remove any remnant of that driver.
Step 2 - Install 13.12
Step 3 - Create a batch file that you can use to provide cgminer with these startup options, ie: c:\neoscrypt377b\cgminer.exe --neoscrypt -g 2 -I 14 -w 32 -o http://bla.bla:12345 -u XXX - p XXX
Step 4 - ensure that you’ve deleted *all* .bin files created by any previous run attempts with that other driver. Wherever you run the batch file from, that’s where the bin files are created. If you’re using CGWatcher to launch this, the bin files will be created in the actual cgminer home directory, go delete them. I recommend creating a new directory called “neoScrypt377b” and placing your batch file there - this makes sure that you’re using all new bin files.
Step 5 - Now run the newly created batch file. Cgminer should launch and your GPU’s should hash in the upper 70’s to low 80’s. This will also create a brand new bin file using these settings. Now close it.
Step 6 - Run the 14.X installer and upgrade the driver (I’m using 14.9). Now when you run the batch file, it will be using bin files created with 13.12 - but utilizing whatever extra capability is enabled with 14.X.
I’ve done this on several different rigs now and it’s worked exactly the same with every R9 290 card I’ve touched across 4 different manufacturers (stock card settings). The key is creating those bin files with 13.12 installed and then using them after you upgrade to 14.X. Sometimes people don’t realize where the bin files are being created to be able to delete them. If cgminer sees a bin file with the same name in the directory it’s looking at, it won’t even bother trying to make a new one for you regardless of what driver you’re using. Hopefully this helps someone out.
note: If you’re using CGWatcher… You need to add the --temp-cutoff and --temp-overheat settings or it might throttle the GPU down and decrease the hash rate. When mining scrypt, these GPU’s got hot and pulled a lot of power. As of 3.7.7b they don’t use nearly as much power or produce as much heat…

Sweet, driver changes. The mining rig has asics attached to it now, so rebooting is extra steps…
You mention a certain set of settings, and that they will get 70 to 80 khs. Using those settings here only nets 45 to 55 khs, but I’ve gotten up to 75 kh/s with other settings in 4 or 5 different combinations… I think I’ll be trying yet more settings before and after doing the driver switch.
The question is, do I really need to go back from 13.25 to 13.12 and re-try all the settings, before going up to 14.whatever driver? (I just checked, there’s 58 bin files…)
-
The reason there are so many .bin files is because every time you make a change to the .bat command line it will make a new .bin.
Changes such as from -w 32 to -w 64 or -I 12 to -I 14 and so on. If you check the .bin file name with the newest date and time it
should have numbers in it that reflect the -w numbers that are in use within its name.

Anyone know how he achieves such a high hashrate?
First guess is that he got about 40~ R9 280x
Second one is that he got a miner which is way more efficient than the public one…

I’ve changed driver versions so many times now that it’s practically a science. The key to driver uninstall is the DDU app. Without it you leave behind too many files and things start crashing and not running right. Someone else on this thread was talking about not going beyond 13.12 for performance reasons. Back when I first started messing with this stuff it was with 7950’s and by going beyond the 13.12 series it definitely impacted performance. I theorize that you’ll see the bump I was talking about just by reverting to the older stuff. I really don’t know why it makes a difference, but I’ve gotten great performance out of my 290’s by doing exactly what I said. 13.12 bin files seem to be gold for me when paired with 14.X. What I found is that the -g 2 setting doesn’t do anything for the 290 unless you have a 14.X series driver installed. Once you install 14.X and use the 13.12 bin with -g 2, it causes that performance bump up into the 100-110 range.

I know why they are there… The point of that was that I’ve tried a fair amount of settings in an attempt to get any sort of speed with these cards, instead of just asking for someone to give me free settings. ;)

Ok, I’ll delete the 13.25 bin files, dig up the 13.11 drivers and roll them back, try a bunch of settings, then install new drivers tonight when I get home from work.

There is a better kernel, but it needs more tuning.
