Did you try increasing your virtual memory? I always heard that you should have a 1:1 for your combined card memory. So in your case I'd go with 64gb. On a 120GB hard drive that might be difficult. Personally I have 500GB SSD on each of my rigs. Maybe you can add another cheap SSD and just use that for VM?

You could also try just enabling one card at a time and see how many work?
Miner Properties > GPU Selection at the bottom > Use selected from list > (Select just one or two then hit OK) > See if it runs (stable.) If so, add another until it stops.

I also use Awesome Miner for all of my rigs and I'm not having any issues with Claymore 15. Alternatively, try PhoenixMiner. If you have the same problem then it's probably not with the software.

Addressing this to all lovely members who are trying to prove with inexhaustible energy that CREDITS is a bad investment.

Since you had enough determination to muddy this project, then be consistent and check article from that link.
Thanks to you CREDITS project provides us with further evidence, that is legit, and assures us that we invest our capital well.

Once again I am impressed by the level of communication between the Credits Team and the community.
They create a completely new definition of interaction with investors ! :-)

I would've really liked if Halong would've been more open so far.

They said they will be better option than Bitmain.

Instead they are even more closed than Bitmain when it comes to the information available.

So it's not much of an improvement.

There are a few alternatives and I think this will boost the price of the other coins while making Ethereum lose some money in the transition.

Hello

How do i represent core voltaje -60 in claymore line commands? I want to undervolt using the claymore bat.

Thanks

Somebody said Windows might not like more than 5 GPUs without some fussing about, just heads up on that if you use that OS. Also my HD7990 is an AMD reference card.

I can get 155 MH/s on UBQ with 3x HD7990 running win 10 with stock drivers. Try a UBQ, EXP or MUSIC pool and get back to us.

use this batch file:

ubq_pasl.bat

or this bash file:

These babies’s are monsters, Large in size and Power hungry. Need some help since this is my first rig and I’m a newbie of sort’s. Well here is the spec’s of the rig.

1.   1 x ASUS Rampage IV Extreme LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 Extended ATX Intel Motherboard
2.   4 x PowerColor AX7990 6GBD5-2DHJ Radeon HD 7990 6GB 384-bit x2 GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support
3.   1 x LEPA G Series G1600-MA 1600W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Power
4.   1 x CORSAIR Vengeance 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 Desktop Memory Model CMZ16GX3M2A2400C10
5.   1 x Intel Core i7-3820 Sandy Bridge-E 3.6GHz (3.8GHz Turbo Boost) LGA 2011 130W Quad-Core Desktop Processor BX80619i73820
6.   1 x SAMSUNG 840 Pro Series MZ-7PD128BW 2.5" 128GB SATA III MLC Internal Solid State Drive (SSD)
7.   (Just in case More is needed or for rig 2.0) 1 x COOLMAX ZPS-1600B (14642) 1600W ATX12V v2.31 & EPS12V v2.92 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular
8.   4x PCIE X16 Risers
9.    Win7 64bit OS
10.    Reaper latest released beta for 64bitwin7
11.    Latest Drivers & bios.

Each 7990 has 2 7970 Gpu’s. ☺

Here is the question’s and issues I have come across.

When I install one 7990 everything is groovy, when I install the second the system becomes unstable and errors & various blue-screens of death occur.

Here is what I found out and tried.

Called AMD they said you can only put 2 7990’s on a mother board because they do not make the drivers to sustain them, they are already 4 7970 chips when using 2 7990’s. I called power-color and they said call AMD and update drivers. Removed old drivers and download the latest stable release and even tried the beta version without success. Flashed the bios to the latest version. With and without risers.

My results have been 1.4 Ghz at times or 8,000 to 10,000 khs but starts degradation cycle to 800khs.


Questions.

1.   How can I add successfully one more 7990, for a total of 2 connected to the motherboard per the AMD recommendations?
2.     How do I max out my cards production via the reaper miner? Optimal reaper settings for my rig.
3.   Why the High stale rate of 30-90%?
4.   Is crossfire possible?

Thanks for your help with this. Have many more questions but been up for days working on this rig .
