How can I start this modified cgminer? I've only used guiminer until now.
Can I put a bat.file of the normal cgminer in the folder and edit it?

can't set --thread-concurrency to more then 4096 or i get the following error (280x):
Error -61: clCreateBuffer (padbuffer8), decrease TC or in crease LG
Please help

How much system RAM do you have? I know it can be difficult to get cgminer to launch if system ram is low, as it uses it during startup (but once it's running, hardly uses any).
What lookup gap are you using?
problem is fixed.
setx GPU_MAX_ALLOC_PERCENT 100
solved the problem, but thanks for your offer to help

The only thing I've needed to change for Vertcoin is thread concurrency. These seem to be the optimal ones for the cards I've tried so far:
R9 290: 24550
7950: 19712
5850: 5120
R9 290: 24550
7950: 19712
5850: 5120
Just keep in mind when changing Threadconcurrency think about changing Intensity as well. running high intensity on low concurrency can be detrimental

if use a .bat startup file, it will load my other cgminer scrypt console
Sounds like you didn't change the path to the new vertcoin cgminer
WOW thanks guys!! Dont all help at once will ya.... 
anybody 
hi can someone please help, for some reason nothing happens when i hit enter in the modded cgminer after i input anything to the console?? also if use a .bat startup file, it will load my other cgminer scrypt console (changed console background colour) although its a diff folder and no linked files are in either, but will crash anyways?? please this is driving me crazy. BTW am using low settings recommended on here...got sap r290 * 6...thanks in advance
7850 from Rasetsu:
--thread-concurrency 2048 --lookup-gap 2 --gpu-engine 1100 --gpu-memclock 1000 --gpu-powertune 20 -w 256 -I 13 -g 1
Gives 170KH/s
My 6 Platinum Edition 7850 1G card using this set to run only five cards What is the reason? --thread-concurrency 2048 --lookup-gap 2 --gpu-engine 1100 --gpu-memclock 1000 --gpu-powertune 20 -w 256 -I 13 -g 1
Gives 170KH/s
Good day to all usernames.

Is this ok? or not?

This gives me nothing but HW errors with an r9 290 and 4gb RAM but runs fine with 8gb. The only way I can get rid of the errors is by setting the intensity to 13 which only gives 250kh/s. Any suggestions?

Heya
using asus R9 280X but i can't get over around 230kh/s (should get to around 350 kh/s)
can't set --thread-concurrency to more then 4096 or i get the following error:
Error -61: clCreateBuffer (padbuffer8), decrease TC or in crease LG
i'am using VertCoin-CGMinerCPU-Aleks_N on windows 7 64-bit
any help very welcome - thanks!

try adding
Code:
-g 1
everyone´s posting configs with -g 2, but i have to set it to 1 otherwise my hashrate drops to ~ 150 kh/s
what values for the thread conncurency di you use. As far as I know no r9 280x is working with <4096. To many HW´s. Did you try to set a value between 8100 and 8300 ?
nope the same error with -g 1 if i set tc higher then 4096.
but i'm at 310 kh/s now (check some of my later posts for the config.) and i think this is not to bad for my gpu

The custom CGminer is giving me NONCE hardware errors, regardless of changes to my bat file. I have adjusted thread concurrent, lookup gap, -g, added/remove the --scrypt flag, etc, etc.
The one time I did get any accepts, there would be a NONCE error, then a burst of about six to ten accepts, then nothing for about a minute, then another burst.
I have two water cooled R9 290's running the --no-adl flag, otherwise CGminer just shows a black screen since there is no fan RPM input.
CGMiner - custom from Vertcoin webpage.
AMD APP SDK - 2.9.233.167
GPU DRIVER - 13.250.18.0
I have averaged 830kh per card at intensity 20 on any other coin.
P.S. The six minute post lock is absurd.

Have someone successfully setup it for 7870? I've played a week with no luck. Only HW and rejections. Probably bruteforced almost all possible combinations of intensity and TC with step of 256 and a lot of random non x 256 values, still the same. GPU and mem clocks are default.
i have more then one worker, all with the same gpu's but one one i have to set the gpu-engine to 1070 (default for the asus R9 280x gpu)
Is 1070 really the default clock??? That sounds like quite a big OC to me, my R9 290s default clock is 947 so I would have thought even factory OC'd 280X's would be no more than around 1000mhz
well from asus site:
GPU Boost Clock : 1070 MHz
GPU Base Clock : 970 MHz
http://www.asus.com/Graphics_Cards/R9280XDC2T3GD5/#specifications
but my gpu is running with 1070 after installation on my w7 workers without any tweaks from my side. so i call it default even if asus says boost clock
.2 of 3 workers are running with 1100 now, what i would call oc heheh
the strange thing: the 1100 setting ist good on my old asus mb with an old intel Quad (Q8400) and 4gb ram and a brand new gigabyte mb with a i3 and 4 gb ram.
but on a brand new asus mb with a i5 (same chipset as the gigabyte mb) and 8gb ram i have to use the 1070 setting to avoid falling back to 240 kh/s
i wonder why
? makes no sense for me i have more then one worker, all with the same gpu's but one one i have to set the gpu-engine to 1070 (default for the asus R9 280x gpu)
