Wolf is correct.  Additional improvement to the OpenCL Kernel can be made but, they would probably allow for a small speed gain.  Unless of course, Wolf or somebody else out there can figure out a way to calculate Keccak rounds using fewer VGPRs (General Purpose Vector Registers).  The current usage of VGPR is what keeps this Kernel at a 20% utilization in AMD GPUs.  

As for the nVidia miner question, this miner does work with nVidia GPUs but, it is significantly slower due to the nVidia's architecture.  nVidia GPUs favor floating point calculations over ALU.  This algorithm (like any other hashing algo) relies heavily on ALU power.  Unfortunately, having the biggest and baddest Floating Point Processor doesn't help here.

navybluevip. I will pay you 1000 KHC to fix your miner on nonce-pool. Just fix it and pm me your address.

just curious, what is wrong with his miner ?

Dev,can you add masternodes or something like InstantX to speed up transaction ?

@Dev,KHC is great coin with brand new algo,esp when most algo are raped by FPGA&ASIC.

Everybody can see dev's hard work and his talent as a qualified dev.

Dev,could you please contact poloniex ,bittrex,bter ? I think they will be interested with this coin.

Ignore the warning.  It is fixed in 0.5.1 which I'm releasing this weekend.

Dev,can you add masternodes or something like InstantX to speed up transaction ?

My understanding is that masternodes are meant for PoS coins only.  Kryptohash is a pure PoW coin.  Honestly, I haven't looked into masternodes at all.  I have my own ideas  that I want to develop for this coin moving forward.

Also, I really don't understand the need of InstantX.  Not even with credit cards you get instant transactions. The only thing that it is "instantaneous" with credit cards is an authorization code that just tells the cashier that the card isn't in the black list or above limit.  At the end of the day, the Retailer gets a final tally detailing which of the transactions that got authorization code are approved and which ones are rejected.  I know this because I used to work developing SW for POS 15+ years ago.

Finally, with PoW coins, having Instant transactions is calling for unnecessary trouble.  Bitcoin has 10 minutes block time for two reasons. 1) The accepted blocks take time to propagate through the P2P network and a block might take a good 2 minutes to reach every corner of the World; 2) Each entry of the blockchain consists in a header plus the list of In and Out transactions.  Reducing blocktime increases the usage of HD Space. It is less efficient from the storage point of view, since you are storing too many headers for only a handful transactions.    

I believe 10 minutes is too long so, in KHC I'm using 3 minutes. Anything below 2 minutes is just synonymous of trouble.

New Wallet version 0.5.1 available.


Changes since version 0.5.0

- Added checkpoint at block 50,000. Network transition to KSHAKE320v2 is now complete.
- Bumped Block header version to 2.  This solves the Warning about having an obsolete Wallet.
- Reduced mandatory flat fee from 0.5% to 0.2%. Minimum fee is now 10 Kryptoha-toshis or 0.00010 KHC. See ** below for explanation.
- Reduced the network Subsidy/Reward from 50 KHC to 25 KHC beginning at block 250,000. See ** below for explanation.


Download new Wallet 0.5.1 from GitHub:
https://github.com/kryptohash/kryptohash/releases/tag/v0.5.1


(**) Note from development: Due to the very competitive nature of crypto-coins today and based on feedback we've been receiving, specially from Exchanges we've been in contact with since the launch of KHC back in Dec 2014, and because the Kryptohash network has successfully transitioned to the new and stronger PoW algorithm version 2, we have decided that it is time to make a couple of adjustments that will help increase the activity in the network which we believe will attract new people and Exchanges to adopt KHC.

I believe KHC will have a bright future.

I'm getting 330Kh/s on my 290x

What does your config look like? I do not see even close to that.

With AMD HD 7xxx and later GPUs, running the latest Omega drivers, you have to use an option called --cl-opt-disable.  For some reason these latest AMD GPUs with GCN architecture work better when you disable OpenCL optimizations.  On the other hand, this option doesn't have a positive effect on older AMD GPUs and nVidia.

Example for my 290x:

cgminer --kryptohash --cl-opt-disable -o http://127.0.0.1:38912 -u {RPC_username} -p {RPC_password} --shaders 2816 --shaders-mul 8

Very important: Don't forget to delete the kshake320v2%YourGPUname%.bin file inside the cgminer directory after you add/remove the --cl-opt-disable parameter.  It is the only way to force cgminer to recompile the OpenCL kernel and include/remove the cl-optimization flag.

Urrr?  I'm only getting 280 Kh/s out of my R9-290 and I've got it cranked up to 1175!  Same too simple to fail config, obviously with shaders at 2560.  But... duh... let's go through those cl libs.

Yeah, runs kinda hot eh!  Shader is a cozy 45C but I've still got this 10-15C discrepancy between that and the VRM1 block.

Edit:  Ah bugger.  Right, throttling due to power.  I was cranking it for a low power algo earlier and had upped the voltages.  Interesting cards, the 290's, I'm used to pushing it 'till it moves, but with these you've gotta finesse.

Boo-Yah!  326 Kh/s @ 1125/1250.  Shader 45C & VRM's still needing a heat-sink (59C).  Now for the 7950....

Check it... notice something about the mount here?  Cooler Master Seidon series...



They are exactly matched to ATI card heat-sink mount holes.  It's the easiest mod around, and I'm sure there are a lot of used units out there.  I can't get my 7950 over 70 C, over-volted and shoving hard!

[wr104]

How about the Seidon 120 XL?  Would it be enough to keep an AMD HD 7970 cool?  How do you deal with the RAM and VRMs temperatures?

It's actually the 120 that I have.  That was just the first good picture that turned up.  As for how well it works, not much difference between the 7950 and 7970...

Ok, wish I had more on tap but... 7950 @ 1200/1600 Heaven 4.0 run, Max temp = 43C, VRM's at 48.

Firestrike run @ 1240/1740.  Assume everything is under 60C.
7950 after a 3Dmark-11 run.  1200/1600.

Same results with a 6950.

You're right in guessing that the real problem is the VRM block.  Basically, heatsinks and rig some fans, that's it.  You'll never have to worry about your shader melting down though.

Totally lucked out there in getting two Thermaltake 2.0's for $22 each, because they had the wrong firmware on them (oh boo hoo!)

$200 chip, $150 motherboard.  Suck it Intel!
