4ch 10ch...what's meaning?

[MarcusDe]

@claymore:

1)
Could you make option to send 6-ch shares too?

2)
I have 4x280X rig
When I set GPU_MAX_ALLOC_PERCENT=100 after some time (from seconds to few minutes, sometimes longer) some of miners start to eat RAM without end.
Then they ofc crash. I'm talking about Giga Bytes of RAM.
Without setting that variable all works just fine, but efficiency is lower.

Yes, I have correct drivers, etc.

3)
What should be gpu core/memory settings? Core as high and memory as low as it could be done, or like with scrypt?

PS.
Good work, rly good work :-)

1. Ypool does not accept 6ch shares.
2. I saw this issue only twice on one of my rigs. It is very difficult to duplicate, so it is not fixed yet. But hope I will find the reason soon.
3. Core clock is the most important thing. But don't overclock too much.

It means length of Cunningham chain found:

Can thank you enough Claymore for your work. My rig is profitable again 'cos of you

Hello,

I have very low CPU usage ... about 2%/process.

GPU 4 x 280x
CPU E5-2670 v2 10Core @2.3 Ghz

It is normal ?

[liifer]

I have 2 * 280x Asus DC2T and 1 280x Sapphire Vapor-X. i5 processor. 13.2 AMD driver. Is this normal? 4ch/h for each is around 21k. Running 2.0v for 4 hours.

It is not normal, check screenshots of other people here, for your card you should get about 120K of 4ch/h, you get only 21K.

Reinstall catalyst v13.12, reboot computer and disable overclocking, it helps in 99% cases

Help Guys.

i have two rigs with 5x280x each! exact same hardware pentium haswell with h81 pro btc
with version2.0

the first rig works perfcet. some gpu usage ups and downs but still works.

on the second rig the miner doesn't work for any of the cards,as the instance launches the display driver crashes and the TRT is on 0.
anyone knows what can cause this? cgminer still works perfectly on this rig with 3.6MH/s.

running 13.12 on both rigs

Same here.
Reinstall win7-64 and 13.12,still don't work.

g1610 h61b 8G 270*6 doesnt work.
Only main card plug on pcie 16x can get 60k 4ch,98% GPU useage.
the others got 99% GPU useage at the first 2 senonds,and drop to 0.
it can run any other crypto like: scrypt,scrypt-N,X11 etc, use all 6 cards.
an other rig with 280*4  works fine, 110k 4ch per card.

Thanx. Although my computer crashed during driver update, I still get ~115k 4ch on all three cards. How many XPM should I get per 24h?

what can cause this? i have another rig with exact same hardware that works! just ssd is dieffrent.
on the rigs that work i have nofee 1 and gpu usage stays on 65-70%. is it ok?

Try everything I can but can't solve,can not mining XPM on this rig.
If you set nofee 1,you'll lost 25% or more hash speed,it is write in readme file.

@Clay
If you need more information I'd glad to help.

@Clay
If you need other information I'd glad to help.

What if remove 4 of 6 cards, i.e. leave only two cards? Do they both work properly? In my tests I used up to 4 cards, never tried >4.

[SpeedDemon13]

v2.0 is nearly on par with the other miner. When is the next optimized miner coming out?

Just reinstalled windows 8.1 + 13.12. FRESH! no cgminer/sgminer ran.

IT WORKS! so far stable each card TRT 500+- nofee 1

I removed 4 cards,one plug in pcie 16x running @ 60k 4ch,another plug in pcie 1x @ 0k 4ch and GPU useage 0%.

Whatever, only the card plug in pcie 16x get work.

Well, now the only option is to reinstall Windows, it helps sometimes, see message above from "gilad215".

Had reinstall win7-64 but dont help,try install win8.1 now,
