Anyone has a good setting for Sapphire r9 290 ?
Can't get past ~515 Kh/s  Sad

Never mind, hashing at 1,2Mh now  Wink

this statement I like (from the white paper by VERT) : https://vertcoin.org/downloads/Vertcoin_Lyra2RE_Paper_11292014.pdf

"Unlike Scrypt, Lyra2 (the principal part of the chained algorithm) allows us to change memory usage and time cost independently, giving us more leverage against ASICs."

so VERT acknowledges theoretical and practical possibility and reality of fpga for lyra2 but with caveat that algorithm can adjust and render these systems ineffective (or needed to be reprogrammed on the chip level)

"At this time we have decided not to implement an “N factor” schedule as it is nearly impossible to predict the future. However, Lyra2RE will give us the flexibility to make changes whenever that becomes necessary"

N factor would adjustments could combat fpga/asic with necessity of fpga reprogramming (and invalidate complete asic investment and asic is cheaper to make and handle so risk to consumers of them is rather big)

also this:

"By contrast, Lyra2RE aims to be ASIC-resistant at heart, allowing for less disruption to miners in the future due to our ability to change algorithm parameters rather than change algorithm all together. It will also free up development time to focus on new features without having to worry about constantly implementing new algorithms every time there is an ASIC threat"

so at least and unlike many crypto VERT is very open about the situation

for fpga, a new micro kernel code has to be created and chips flashed for any parameter adjustments, average user will have to ship device to the manufacturer and wait for new boards to be received back, then VERT community or VERT dev itself sees fpga activity again based on the profitability scale and perform adjustment again at some point it becomes impractical to get fpga chips reprogrammed every time

we are looking better and better from the long term investment strategy and I wish this would have been done sooner, but coin has been re-launched and people can rebuild their portfolio from the bottom instead of from the top.

His miner is probably displaying the wrong numbers, no idea why tho. I'm willing to bet whatever pool he mines on reports closer to 600kh/s per card. With major overoclocking djm said he was able to get 660-670kh/s

My miners must be submitting shares like crazy because the pool I mine at is reporting 5,000-9700 kh/s all day per 6 card 750ti rig

Yes.  As stated in my previous post, my miner (SP fork fork of ccminer - http://github.com/sp-hash/ccminer) is displaying higher hash rate than what's reported by the pool.  I'm getting 620-625 kh/s per the pool.  On my EVGAs the gain from overclocking is quite small.

statements like this contribute 0 to anything please read my previous post on reasons behind the change, you don't need to be negative coin has reached nice plateau already and many have nice chance to get started in crypto with it in the right way, with few GPU cards and some fun, please think twice before making post like this it as it really does not do anything literarily

Ditched X11 with my working GPU rig and now have it mining VTC.

I've got a half dozen more 750ti's that have been gathering dust for months... I might rebuild that rig in the coming days, especially if the news is as good as has been reported when I whip out the kill-o-watt meter tomorrow.

Vertcoin always had the best community and ambition.  The last few months have been trying, but with the hard fork to Lyra2RE, we can start getting excited again.

I'll post power numbers here tomorrow.  AM3+ ASRock boards, Sempron procs, one rig with EVGA cards (running), and another with PNY cards.

The EVGA 750ti's are hashing at 720-725 kh/s each, except one that's stuck at 710-715.



EVGA 750Ti's are factory OC'ed, or more? what clocks?
(I have 690kH/s with Palit StormX Dual, "factory OC" only)


How are you getting 720-725 kh/s out of your 750tis ? I have 36 evga 750tis (using your kopiemtu) and the most I can get is 625 kh/s out of each card


I have no more than 700kH/s, rather: 688 - 689 kH/s

I think Lyra2RE can be done on FPGA - just depends how much you want to spend. From my understanding, FPGAs are EXCELLENT at logical operations, but fast memory for them gets expensive quickly. 6KiB is not a lot of memory; I think it would be cheap - but that assumes you only want to run one thread at a time. I think, for best performance, you'd want to run dozens, or maybe even hundreds of threads - then you'd start getting bit by the cost, I think.

Anyone with actual experience doing FPGA work, feel free to correct me/chime in.

Size and frequency increases are mainly what you get for more expensive FPGAs. When I refer to size, I mean the on-chip memory size. DDR or flash memory can be connected to FPGAs, of course, but using them increases the latency. For the fastest operations you would want to use the block RAM on the chip only. Use this table to get an idea.

http://www.xilinx.com/products/silicon-devices/fpga.html

Xilinx Zynq chips have a system on chip and an FPGA all on the same package, but have significantly less block RAM. You can run linux on the SoC and have direct access to an FPGA.
http://www.xilinx.com/products/silicon-devices/soc/zynq-7000/silicon-devices.html

As for cost - they are expensive, as you probably expected. The low-mid range Kintex 7 FPGA development board costs $1700 from Xilinx. Development boards have tons of features and hardware that would not be necessary for this application, so cost may come down, but spinning a circuit board for an FPGA is not an easy task.

Maybe that for someone will be helpful, you can set lower power usage on 7950/7970/280x cards just use this settings:
Drivers 14.4
Msi Afterburner 4.0
Core clock 715Mhz
Mem Clock 1500Mhz
core voltage 900mV
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe --algorithm Lyra2RE -o stratum+tcp://pool.verters.com:4444 -u xxx -p xxx -w 64 -g 2 -X 128 --no-submit-stale --expiry 1 --scan-time 1 --queue 0

Hashrate is almost like with 815Mhz (956mV) core but less power usage.

On 290/290X cards you can also do it.
If You flashed 290/290x the Stilt bios, use max 1450Mhz memory clock, when is original bios use 1500MHz mem clock.
Try 715Mhz core clock and you can low core voltage in msi afterburner.

On this settings i have on 280x (hynix) 925khs, on elpidia 825-850khs
On R9 290 cards 1200khs.

What's going on with price :/
last 3 days,main pools had fake-share problem,and wallet was unable to RPC solo mining.
the diff was low ,someone had special skills to get more cheap coins.
it was high profit for those people.absolutely, they should dump as i told .
when the pools are fair for everyone,the difficulty and the price will reach equilibrium,and price will  be stable.
maybe FPGA  was made,but i checked pools these days, i hadn't seen large true hashpower,except fake hash.
as i said, to check if FPGAs or ASICs are made,the profit will prove ,no matter where they are,they cannot hide.
whattomine.com  shows the profitability is 663%,i believe it is absolutely pure GPU coin.

I believe so too, I see low hashrate on my pool currently, maybe the interest is just somewhere else currently.

one could also trace block generation volume (from blockchain) and compare to reported combined network hash rate in a time delta

great post thank you (also thank you @nonny12 for his fpga write up, very interesting and encouraging)

Probably FTC? Can't be X11.
FTC Profitability is 1447%,very high now.
FTC and other NeoScrypt coins,all have high Profitability,this is sign of pure GPU algo.
X11,X13,if you trace whattomine.com for months,the long term profitability was lower than 300% ,that means a large  FPGA farm was running.
