What is your R9 290 Hash rate ? for mining UltraCoin

I got 30 kh for each card , it is true ?

There's this AMA going down today.  Are we just ignoring that this has just been/is a fuckton of wasted effort?

I say this because, after all, this is the state of things:




I get the feeling that much ado is to again be made in order to co-opt good men into another pumping of this codpiece yet again.

I beseech you, brethren, find something fucking worthwhile to do with your time instead.

Yes



The great silver will have a great future



Come on

Here you go, I was the first to post it which now everyone is using AFAIK.

280x(7970) @ 60Kh/s

55Kh/s at 1025/1500 @ 1.075v
60Kh/s at 1110/1500 @ 1.150v

1. Use latest YACMiner. https://github.com/Thirtybird/YACMiner/releases
2. Use following core settings: (Add other settings, more pools as needed)


Note: This may ONLY work on a PC with 8GB "physical" RAM regardless of VM size. (I tried up to 32GB)
If you have 4GB RAM machine and it fails, try using a lower buffer-size of 1760 and -R of 6144 or 5888.
As the rawintensity is lower, you will end up with a lower hash rate of about 45Kh/s unfortunately.

Some tutorial on YACMiner for everyone

YACMiner allows finer control of the intensity value so you can squeeze every bit of its hash rate which ultracoin-miner cannot.

--buffer-size cannot go over the size of your video card's RAM amount. It's usually around 10% less value.
-R is basically Intensity equivalent in cgminer. YACMiner allows for more granular in-between Intensity values. (e.g. 12 = 4096 & 13 = 8192)

Goal is to try and squeeze in as many threads (intensity) in to the amount of buffer without it going into dynamic memory.
So first try to find the largest max buffer size your system will work with. Go up in increments of 128 until it fails to start.
Depending on system RAM size, you may need to start as low as 50% of your single video card's RAM amount. (e.g. 3GB video card  1536)
Once you know the max buffer size that works, set it as that and leave it alone.

Now just adjust the -R value in increments of 128. Good to start from something low such as 4096 and work your way up.
If you set it too high, you will either get HW errors and much less WU or it'll just fail/lockup/crash etc. Dial it down if so.

Lastly, check your WU over at least 15-20minutes. Clocking higher might givss higher hash rate but WU might not go up.
You might end up using 5-10% more electricity but end up not actually doing any more real work. So keep an eye on WU.

For those of you wondering, TiPS will still appear on the profitability list, but multiport will not target it.

Hey some 290 settings, this will give 62khash at 977core :

--scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -I 16 -g 1 -w 64 --thread-concurrency 85000 --lookup-gap 3

This is better than going 90000 TC with lookup-gap 4. Itensity of 17 and higher slows the system by a huge amount(at least for me). There may be room for improvement but I have already achieved 280x/290 ratio of 0.81. I have 8gb of ram + 16gb of pagefile(set as a constant).
