@springdev

you havn't enough system memory. try it with 2 gpu and your config will work... so with 4 gpu you should rise your system memory or try it with -R 1280 buffer-size 1295, but these results will not satisfy you.

good luck

If you don't understand how something work don't fool people lol! Ram have nothing to do with the card after the start of the miner because it is used once just to carry the data to the card. The actual problem with the dead/sick gpu's is caused by the vram clock.
BTW 8 gb ram is enough for 6 gpu's and even with 4 gb you can run 6 gpu's no matter what os you got.

Thx. But the problem is my system with 8GB of RAM (not 4GB). And I've been mining UTC + NF14 very stable in 4kh / s. Has anyone encountered this problem? And how you solved?
Plz!

8gb isn't enough for those 4 cards and decent settings at n15.

If really need more than 8GB of RAM for NF15. So UTC anti-Asic and anti-VGA +++
I do not think so!

Don't be deceived by fools!

If you run a LINUX OS, you don't need more than 4GB of RAM at NF15 OR NF16!!!! Windows is a different issue...

I will be back for the GREAT discussion with Hilux and Kracko.

Who are you calling fools? You need to STFU and GTFO. Just my two cents.. Undecided

Oh well..at least we are still above Vert. Cheesy

Fabietech will be happy Grin

Vert is dead and Ultra is still stable.

Seems Vert has had CPR - above UTC now?

I have 4xR9 280x + 4x7950 + 8Gb RAM/system, win7 64

This my config (http[Suspicious link removed] --scrypt-chacha -o stratum+tcp://stratum2.tumblingblock.com:5555 -u worker -p x -R 2560 -g 1 -w 128 --buffer-size 2590 --lookup-gap 8 --gpu-engine 1000 --gpu-memclock 1250 --nfmin 4 --nfmax 30 --starttime 1388361600

But all VGA are in turn being sick - dead...

What I wrong in that? you please just help!

Hi, What is your setting for the R9 280x?

gpu 0 disabling gives the error.

Try lowering gpu engine value. You are overclocking your R9 280X card with clock set @1200 MHz.

did not work.

del *.bin
yacminer --scrypt-chacha -o stratum+tcp://stratum2.tumblingblock.com:5555 -u username -p password -R 2560 -g 1 -w 128 --lookup-gap 8 --buffer-size 2590 --gpu-engine 950 --gpu-memclock 1200 --temp-cutoff 85 --nfmin 4 --nfmax 30 --starttime 1388361600
pause

'Error 4 - Kernal blah blah blah' usually happens when you are setting your buffer size too high for the amount of system ram you have

Hi, What is your setting for the R9 280x?

N=15 -> 8M
8/24= 0.3333

0.3333 * 2560 = 853.8

What is idea with this lookup-gap 24 with this buffer size and with This Raw intensity?
(exept that result is still not so bad if also real accepted works are nearly 1.2kh/s

Pretty sure it is just UTC difficulty algo being too sensitive and 'correcting' too far either side of optimum. Things seem to get a lot more twitchy at these low low N15+ POW diffs. Also as a POS/POW hybrid adjusting teh difficulty is even more complicated as the POW diff is in feedback with the POS diff so that a weighting between the two is maintained. I don't feel like looking it up but I have a strong hunch that the YAC difficulty adjustment settings are not as sensitive so you will not see as much oscillation in difficulty if you are trying to compare the two coins.

Yeah, the Peercoin exponential retarget is much more precise. And of course, what scrypt-chacha folks are used to seeing behind a network rate. I definitely prefer the stability this retarget brings, but since it only uses the last two blocks it's vulnerable to time manipulation.

Digishield can be oscillated more. It tends to overshoot a bit at the extremes. But while it swings more than before, the blocks still have an acceptable spacing over time. It appears to scale up nicely- Dogecoin doesn't appear to having any issues with it. I like the asymmetric rise/fall. Being able to correct downward faster than upward was a positive to making the coin more available to our dedicated miners by quickly recovering from those difficulty levels that leave the chain stuck. It's less affected from time manipulation. But, at the difficulty lows and the highs the network hash rate seems to go beyond the actual a bit when it overshoots.
