Hi!
I've got question about POS system.
When i will have coins form POS?
F.E. I have 500 cloakcoins and I've mined trasaction only once for 0.1 cloak.
How often i should get coins from this POS and how many?

My wallet should be oppened without a break?

Where you have this rig? Temperatures so good
You have special place, or smth?
Maybe undervolting?

In your cgminer folder

I use risers like this one.

I checked this out on my 4xr9 290 rig with this MB and here what i've got:
If i connect 3 card via Molex, rig wont start up.
If i connect 2 card via Molex, rig starts up normaly.

What's the difference? In both cases I use additional power cable to onboard 6pin slot for PCI-e slots

With powered risers?

Is it better to connect molex to riser?
What if this Rig works properly for few days without molex connection? Is it safe?

This board have additional power connect for pci-e.
I can connect them via riser with power. You think there will be no errors?
So I can easily connect 3xR9290OC GB to 1000W?

Maybe you can tell me which stuff will be best for this rig
I'am trying to get r9 290 with 3 coolers, becouse standard r9 290 is too loudly for me.
I run 4xr9 290 on this motherboard and it works good without power on risers.
My risers is x1x16.

Hi!
I have a question for PSU, becouse I cant find stable information.

I want to connect 5x r9 290 Gigabyte OC card Wind Force to MSI z77 Mpower via unpowered risers.

My plan is:
To buy 2x1000W PSU and one will have 3xGPU and other one 2xGPU+MB

So my thinking is:
r9 290 card pull power from power supply and motherboard like this:
75 W (6-pin) and 150 W (8-pin) for max, plus 75w from MB.
My question is that combo will be enaugh ? IF yes, which PSU should i choose. I thinking of:
LEPA by ENERMAX 1000W 80+ BRONZE HASWELL or Chieftec GPM-1000C 1000W 80+ Gold Modular.

Have fun with mining

It does not deppend on tc, just one of best tc for this card. It all depends on setx max alloc.
Simple step:

1. Run cmd
2. Setx
3. Exit cmd
4. Run cmd
5. Run Cgminer.

And setx commands in windows must be set only one time, so now it all should work properly

Just answer simple question, did you set both setx command and restart CMD?
Do not use any batch file, just go to catalog with cgminer and run
cgminer with your pool account and tc 22000. If there is error that this is too much,
probably there is issue with setx options. I have the same when i don't use this option and restart cmd

How to manage 4xr9 290 in 1500 Enermax PSU?

Any1 now how to make it? I'am now at a little oc (1000/1250) and having 885 kh/s per card, but Wattage is to high, like ~1350 and my PSU restart rig sometimes.

Those are 11196-19-20G.

Any stable bioses? Or how to undervolt them? I tried msi afterburn and I can't chage voltage there..

I have stable temps ~70C, and everyone in each sites have above 1100 gpu engine.
I dont have AMD driver crash. This could be possible, that i can set engine higher than 1000?

Hi!
After few days of mining, my 3 of 14 Sapphire 7950 boost edition cards just dead (Even PSU doesnt start, when they are connected).

I dont even try to change voltage. They all work on 1100 engine clock and 1250 memory clock.
The other cards restart system without a reason sometimes.

Is there a possibilty, that i buy cards with defect?

Or this maybe my foult? I think 1100 is not too high..

BR!

Did you solve your porlbem?

If not, try to reinstal your drivers (with restart) and then run CMD with admin rights, use both setx 100 and 1 lines, then exit cmd and run it once again!

Now try the very basic cgminer config with pool adress, user and password, and -I 19. Dont use thread, gpu, nothing, only -I 19.
Tell me what you have

So I think the only way it will be change bios by myslef. Any proposition of settings in VBE7?

I don't have access to my rig now, but try to add intensity -19 engine -1100 and memory -1250. This should be enaugh to make ~650 kh/s

@crazyates I've seen this, and want this to be my last option

Hi!

Today i tried to shortcut pin on my z77 mpower, becouse i use x1 x16 risers.

I have 7 slots and all x1 slots + first x16 slot works fine on x1 risers. Two x16 slots does not work with riser (it only work, when i plug card in slot without riser, so i know they are working fine)

Today i tried to make a1b17 shortcut on x16 slots, but it does not work at all. I use power risers.
Should i use shortcut on all slots, even those which working fine without it, or maybe something in bios should be changed?

What i have done:
Plug 1 card in pci-e x16 first slot, make shortcut on seccond x16 slot, plug powered riser x1x16 and windows only see one card.

Any ideas?

br!

Hi!

For now I have 4x HD 7950 rig. Power consumption from wall is 1150. I think it is ~250W per card.
Each card makes ~650kh/s

Is that good power consumption? I heard this is overkill.

I tried to find bios with lover voltage, but all bioses want work with my windows 7 pro.

Cgminer says i have 1.169V and unable to change it there.

Any ideas how to make power consumption lower?
