To all you miners scared about you low hashrate: MRC uses n-factor to increase the difficulty to solve the block algo, so this means that more blocks are mined more calculation power from your GPUs is needed.
The very high doubled hashrates for scrypt jane mining is now gone for this coin.
I can say that at start of MRC coin my 270x were making near 1.2 mh/s and my r280x even more, but now as you can see an 280x gets just around 600khash/s.

However dig more!

However must be told that even if the hashrate goes down because the n factor
the block rewards are increasing.
Now is like 87000 MCR for a block they will go until 160000 MCR for block then will descend.
On the first post is everything explained.

how many khs/s can make r9 280x?

618-624


Really? Can you post a config? I'm getting about 40khs under that right now.


Give me 2-3 hours to get home and I post it

 microCoinminer.exe -o stratum+tcp://mrc.blocksolved.com:3310 -u Del137xxxxxx  -p xxxxxx   --scrypt --Nfmin 4 --Nfmax 30 --StartT 1389028879 --scan-time 60 --expiry 66 -w 256 -v 1 -I 13 -g 2 -l 1  --gpu-engine 1150 --thread-concurrency 8192 --gpu-powertune 20  --gpu-fan 70

It's pretty simple

Interesting, i've got mine undervolted for regular coins, pretty close to yours except a lower GPU engine setting.... maybe i'll tinker some more...

Nice coin! But what's with the "Warning: checkpoint is too old..." ? I'm using the Mac client. The Windows qt wallet won't even run on my PC (crashes).

Devs are going to update the wallet, but there's nothing wrong as long as your client is fully synced you should still be able to send and receive coins like normal.

No memory clock setting for your miner? Ill be buying some 280x's next, but for now I have some 270x's by gigabyte (<3 them), heres my setup ---                                            microCoinminer.exe -o stratum+tcp://mrc.blocksolved.com:3310 -u NoobSauce.xxxxxx -p xxxxxxxxxxx --scrypt --Nfmin 4 --Nfmax 30 --StartT 1389028879 --queue 0 --scan-time 2 --expiry 4 --no-submit-stale -w 256 --gpu-memclock 1500 --gpu-engine 1115 -g 1 -I 16 --thread-concurrency 16000 --temp-cutoff 90 --auto-gpu

im sure I got some more work to do, as well as OC'ing my card still to do. Getting 354 khash ea at this setting. First day I joined I was getting around 1100kh ea card, but even though we are down in hash rate, coins production has actually increased with block reward. For now at least  Cheesy

edit: also, I believe the R9 280's bus width (-w) is 384 bit, and the 290's are 512. (270x is 256) don't know, but may make a difference?

I have 2 HD 7990  Huh

See and use.

PAUSE

2.2 Mh/s now.

Question to the developers and knowledgeable people.

Where official website ?

Tomorrow I will put a powerful pool. Need the latest version of the miners and FAQ.

I have both 270x and 280x from Sapphire, the second one is the Vapor-X version(great cooling). However i have the same your paramaters just different in:
--thread-concurrency 15232
-w 512 (don't know why but my 270x perfom better with this than -w 256)
-I 18/19/20 (every number works without HW errors)
- core @ 1150.

However with cgminer and the 280x cards I cannot put -I  parameter more than 13, and i'm running the 280xs with TC@15232.
And my 280x perform better with -w 256.
Fact that i still cannot understand.

Hope this will help.

Latest miner is on first post in this thread and there is no reason to update it.
Web page address is not published yet.
New wallet will updated soon, but it's not mandatory. (Update needs are new logo,default port, some message info's, new checkpoints)

That is all I know about.

So if you set pool, you can use current wallet and miner versions.
