Yeah I'm using Spreadminer, linked from their OP in the ANN, thanks.

Spreadcoin is not vanilla x11, it's SpreadX11.

You can find the proper miner in their ANN.

The reason I mentioned Spreadcoin because it has a relatively low network hashrate (417 Mh/s) so you'll find blocks fairly frequently (~3.7 hours per 750 Ti).

Solved this, uninstalled pretty much everything Nvidia-flavoured then tried mining UNF again, and it worked. But not before uninstalling the 3D engine software which had also been installed by my previous antics. Didn't bother trying Argentum again, life is too short.

So installed the Spreadcoin wallet and kicked that off this morning, solid 1450kh/s on the X11 algo and 99% GPU work, which one assumes is ok...will wait and see what happens during the day. At least it appears to be working now.

Not until I fix the hash rate I can't Wink

Mine something else, anything that's not scrypt/sha256 really and you might even make a profit. Mine Spreadcoin for example, that you can actually solomine.

Just doing it for the interest and challenge of mining I guess. And if I find a block (odds are astronomical, I know Smiley) all the better for it. That said though, some of the new scrypt coins, when released, offer up the possibility of finding multiple blocks, early on anyway...

What are you doing GPU mining scrypt in 2016? That's a complete waste of electricity.

Hoping the community can help with this one, before I throw the bloody rig out of the window Smiley

I got the thing working again after months and months of inactivity. There seems to be an influx of good coins these days so wanted to start mining again. After hacking about over a few evenings, I got my PC/rig hashing away on Argentum at about 235kh/s on the one GTX 750Ti. And was quite happy with that as a starting point.

Then tuned the card a little after a day or so of finding no blocks (no surprise) and got 248kh/s and all was well. Then the fun started.

Got a spurious Windows Firewall message (no screen prints, as I clicked it away) which is bizarre as I use Norton 360 so of course Windows Firewall reported that Norton was handling inbound/outbound. My wallets and ccminer application were already allowed through the Norton firewall (as I said, it was mining happily, I think). As I say, I clicked away this message and then from there, I wasn't able to get Argentum's client to start up properly. It would start and sit in the task bar, but no actual screen would appear.

Played with the Norton Firewall. No change. Uninstalled Norton, switched off the Windows Firewall which had now become active, reinstalled Norton. No change. But worse now, when I try to mine RELC, my hash rate is a miserable 28kh/s, and it's driving me up the bloody wall.

I think the issue is perhaps something to do with:

a) I went into clean-up mode when the first issue started, and I removed Visual C++ libraries from the PC, which were then requested by the PC when I tried to startup my MSI Afterburner software for controlling GPU fan speed and so on. So I reinstalled these via a (downloaded) installation package for the card drivers from what I thought was the correct source for the card. Now MSI starts up ok, but the hash rate is that miserable 28kh/s. Plus the screen response seems slow. It's for that reason I wonder whether the issue is:

b) Card drivers, related to the fact that my OS is Windows 10 - upgraded from Win 7 previously which is when the card was actually installed (ie, Windows 10 wasn't a fresh install). I wonder whether I've impacted the card drivers in some other way during the clean-up and need to find the correct install for the card on Win 10 in order to return it to full health?

The PC otherwise works fine, responds ok and starts up and behaves as I'd suspect. It's just the hashing rate which has tumbled. I cannot comment on the gaming as I've got an XBox One for that side of things. The GTX was purely for mining. I was on the brink of ordering some bits and bobs to build a milk crate-based rig, just for the fun of it, but I need to get this issue resolved first in order to learn.

Anybody got any pointers please? Cheers all.
