could some one help me out why i get this error when i load up 6 gpu

5 gpu work great but 6th always crash

That seems to be a driver error because the memory addresses are negative. But I'm wondering why the addresses are 32bit long. Do you use a 64bit Windows (I guess 8.1) and which Catalyst driver do you use?

@NaN,
Obviously with 5 card modification works, at least that is written in the previous  billyboy402 post :)
So, this is driver error, you can’t use more than 5 card on one mainboard, driver not support this.
(try to find in forum modified ati driver (edited inf file) that support 6 cards)

That is my previous question: in  is this configuration with six card, works with other miners with other coin mining?

with other miner, on other alt coin, is working well?

@Ykw

I did the experiment for you :)
So, on screenshot you can see the vga1 that is connected on pcie 16x first cmd window, on second cmd window is vga2 on pcie 1x.
https://docs.google.com/file/d/0B3YMX5z3l5htQ21UbGgtZzZ3Vlk/edit?pli=1
There is, however, one catch ;)
The vga1 is sapphire 280x dual oc elpida memomry
Vga2 is Asus 280x  direct cu 2 Hynix memory ;)
I think that Asus is better vga ;)
Anyway, in principle, there is no difference from that of which slot the card is attached.

I know I am being.. a bit annoying.. but if you get the chance.. can you run 2 instances.. separate.. and report the speeds..? =) although you have 280Xs... I would like to see if there is difference over the two PCIe you are using.. over that board.. when and if you get a chance of course.. and.. by the way.. thanks in advance.. =)

@Ykw
From some hours I am running on coin that I don't want to break the miner :)
However this experiment I've done in the past, no big difference on running separate process (one instances to each device).
I remember that I got a little worst collision summary than one instance on all devices (-t 0,0,1,1.....e.t.c.).

if it is on the pci bus, then we must increase but only from 100 to 110 Mhz and get 10% more performance

@Mario241077
You are right, overclocking the CPU/Bus, gives little advantage...
Also if you like experiments, try to give more high process priority, and see the results ;)

I am at the moment on Windows Server 2012, the miner for this coin that mining  now, no source code or build for Linux :-(
Anyway, I didn't run clpts miner under Linux, I had some issues with the libraries there...
Don't believe there is a big difference Linux VS Windows, my experience with other miners indicates that...
No remember where, I saw that "-a 1" option is for optimizing 280x, "-a 2" is for 290x, but may be wrong....

so now I have time :)

I have

CPU Typ   QuadCore AMD Phenom X4 Black Edition 9950, 2600 MHz (13 x 200)
CPU Takt   2611.9 MHz  (Original: 2600 MHz)
Motherboard Name   Asus M2N32-SLI Deluxe  (2 PCI, 1 PCI-E x1, 1 PCI-E x4, 2 PCI-E x16, 4 DDR2 DIMM, Audio, Dual Gigabit LAN, IEEE-1394)
Motherboard Chipsatz   nVIDIA nForce 590 SLI, AMD K10
Arbeitsspeicher   4096 MB  (DDR2-800 DDR2 SDRAM)
Speicherbus   535.8 MHz x2 1066 MHz ungagged mode
Command Rate (CR)   2T
HyperTransport Takt   1004.6 MHz
North Bridge Takt    2009.3 MHz
Grafikkarte   Asus R9290X-DC2OC-4GD5
GPU Codename   Hawaii XT  (PCI Express 3.0 x16 1002 / 67B0, Rev 00)
GPU Takt   1050 MHz  (original: 1050 MHz)
Speichertakt   1350 MHz  (original: 1350 MHz)


While among many things I might think that could impact mining for algos that do not depend on CPU memory. I am still thinking that my explanation to why some have ~5200 and we have about ~4700 with a 290X cards.... is PCIe tech...

PCIe 3.0 has better encoding than PCIe 2.. thus.. costs less cpu cycles.. and makes GPU data to offload better CPU command instructions. I can't prove this right now.. but as I already did some experiments.. over boards that had PCIe 3.. I remember my results.. and they where.. easy better.. for SHA it might not make much difference.. but for scrypt and alike algos.. it makes.

Remember.. it's not the throughput that matter in crypto.. its the latency and command efficiency per Hz or pipeline cycle.

I also have PCIe 2.0.. does anyone has PCIe 2.0 and 5200 col/s with a 290X to prove me wrong.. =) Thanks

Hello, may be you are right, however, I do not think so.
My 2x280x cards is working on mode x1 v1.1. with 30cm extenders ( to pcie x16, second to pcie x1) with old mainboard.
Making  ~9980 -:- 10060 c/m, i.e. ~4990-:-5030 c/m on each card.
I'm not saying that there is no logic in what you're saying, but in practice it doesn't matter, important operations are performed inside the video cards.
Rather may affect the rejected/discard percent of work.
However I don't have a chance to check it, don't have a new hardware ;)

Only the 290/290X get affected... 280X and bellow... do not.. that's my experience. But again.. I am not sure.. too.. Just .. saying.. Once I have my hands over 2 new boards.. this will get sorted..

what chipset you got over that board? I am also considering that PCIe could be splitting (switching) in my case... I have to check.. and therefore creating more "waitting time"...

As I said before, an old motherboard ECS G31, s775, DDR2 4g E6600 :)
