Yes there is a problem with SSL certificates, for me it was just in Safari. On one machine I fixed it by removing the certificates, but it doesn't seem to work on my others. Try Firefox.

I have a gigabyte 7790 with 1Gb GDDR5. Core @1150 Mem @1200 (for less heat)
I'm getting 1.830 MH/s and 0.027 WU/m (currently at fractalcoin)
This is my conf. It's nothing special...


TC doesn't play such important role as in scrypt. I also use 8192 or 2048, without any significant change.
Memory clock also doesn't affect my rate much, so I keep it low to drop the temps.
You can also try more threads (6 or 8 ).
Q/S/E  based mostly on the coin and pool and my experience/hope/illusion/paranoia...

Update: After a full day of mining, the memory clock is again stuck at stock speed (1500).
I restarted the miner but its still stuck. I'm using djm34 version.
I switched to kozmos version (with bins from 14.6), and the clock is again working ok.
I think this is getting too confusing for me to follow...

From what I've read so far, it seems series 5xxx & 6xxx don't benefit as much by 14.6 or the new miners.

Update2:
If the 14.6 opencl files are in sgminer folder, when I run sgminer, mem clock gets stuck @ stock freq.
If I remove them (after I make the bins), then mem clock acts normal. Weird or not, it works.
I've tried this with both djm34 & kozmos versions for both x11 and x13...

I found the opencl files in AMD folder inside \Packages\Drivers\Display\WB6A_INF\B171094 (after decompressing the 14.6 driver package without installing it, or with 7zip)
I don't know which are needed, so I copied everything that had "opencl" or "amdocl" in the filename into the sgminer folder (8 files, dlls & exes).
Deleted all previous bins, and now it's even better (+3%) than using the bins from 14.6 (I have 14.4 drivers installed).

I use a 7790 (seven-seven-nine-zero, a bit weak I know, but only ~70W).
With 14.6 it went from 1.2MH/s to 1.8MH/s but with locked memory clock (core clock not locked).
I removed 14.6, kept the .bin files, reinstalled 14.4 and everything is fine.
If I recreate the .bin with 14.4 I get my old low hashrates again...

Sandor, have you had a chance to look at this please? Something changed after 0.9f, I can't connect to MiningRigRentals with any of the latest versions. I think when they redirect the stratum connection to a different port, it fails?

I'm using msi too, just tried with default clocks for 2 hours, I'm getting 69000 4ch/hr, 1.98 CPD and still crawling up.
set the memory down not affecting mining speed?

Is it support lowend card like 7790 ?

I scripted 600-900 in 1,5,10,25,50,100 increments.  My units do 600 or 50m increments.

I have found that 750 - 850 is the best spot for clocks.

What is the issue running in dual mode in windows?  I can pull my unit out and test it all/ write up single unit dual mining if needed.  It'll be win7 64 bit.

It really depends what mode you are running in. For scrypt only mode 3 plugs is actually way underpowered as you can get just about 20 devices @10W on a single PCIe cable.

The 18AWG wire can handle 10A and the minifit pins/housings are rated for 9A. Theoretically you can pull 9Ax12V=108W per wire pair. I would not push it that far but safely getting 80W per wire pair has been done ad infinum by miners. This gives 80W*3pairs=240W per PCIe cable.

Those numbers from the PCIe spec are really safe and are meant to protect the graphics card and motherboard which we will not be using in this instance.

Single mode is 6W 12V .5A max 10W 12V .84A dual mode is 60w 12V 5A max 100W 12V 8.4A so I would say the 7AMP recommendation is SPOT ON for providing max needed power for dual mode!

So if you are running in Scrypt mode we can safely say 1Amp/1,000ma provided will be a standard number and plenty of power for scrypt mode.

Once cablez finalizes a standardized design he will be able to send out a lot of orders pretty quick.

What is the sefest maximum OC to push this board to when just mining Scrypt? I have the miner hooked directly to my win64 pc since I can not get my hands on a powered usb hub at 10PM at night and just mining scrypt i have it at 850, is it safe to push it much higher??

?

The board says 100ma via USB and 12v (IDK amps) via the 2.5mm barrel plug.

All the power draws are in the power and freqs section of the OP.

I have to complete the testing of running these in mixed mode from the same box before I officially price out dual mode.  Which as long as dual mode works with say one device in dual and 9 in single I don't know that there will really be an upcharge.

Instead of charging a termination fee or anything else I offer extended hosting or sales/shipping of devices.  So yes you would pay actual shipping + materials if I don't have them lying around once the device is shipped to you or a buyer.

Also uglystick is selling two slots so you can buy a device that has not been disassembled if you like:

.5BTC for the device with 90 days hosting.
