Quick Clarifications In Regards To Builds

[quote]Or am I, and I am seriously not wanting to be tongue-in-cheek about this but it crossed my mind so I figured I should bring it up, risking having a fan so powerful that it slows the fans on the GPUs?[/quote]
Thankfully this wasn’t so much of an issue; though that vornado is pushing the GPU, CPU and power supply fans around when they’re not on.
Now my current issue is any time I start tweak settings, clock, memory, intensity, my hashrate dips 50k. At one point, and silly me forgot to notate where, but I raised it where I was pulling 612 but then started getting rejected blocks. Eventually one of the cards reported SICK and the whole thing just died.
So I’m back to stock settings, but I’m coveting the high ends of [url=http://litecoin.info/Mining_Hardware_Comparison]these results[/url]. I’ll keep tweaking I guess.

Uh, with this Seasonic that I got it has two CPU cables. One that fits perfectly and one that looks like it’s for Pentium based boards. Thing is on the back of the power supply, there’s two spots for CPU, and if I use the one that fits the board perfectly, it takes up a PCI-E power slot. The Pentium based one apparently has it’s own socket?
I’m assuming this matters, so how’d you guys get this combo to go? Will be reviewing your pictures for clues.

Dunno what board your running on but the CPU output on the PSU suits the cable that plugs directly in to my mobo.
No magic necessary.
Pics?

[/quote]The GIGABYTE GA-990FXA-UD3.1. Picture for the back of the power supply. I’ve been plugging in the top right hand corner and the cable goes right to and matches the notches (rounded and squared, you know) on the board. That worked for two cards. Adding more I’ll need all 4 of those PCI-E sockets back there, right?
2. This picture shows what I had plugged in there and where there’s empty holes with no pins. On the opposite side of the cable, as you’ll see in picture 3, it’s just 8 pins but the pattern is the exact same as the 8 pins that are occupied that you see in this pic. If I reverse the cable, plugging the eight that were in the board into the CPU only socket on the power supply as you saw on the bottom left of the power supply in the first picture, the extra, empty pins on the bit of the cable I’m showing here is blocked by a square on the board keeping it from being plugged in and the empty pins from overhanging.
3.Here’s the AMD cable that was working but takes up one of my PCI-E power sockets.
4. Here’s the intel cable that can plug into the lower left socket of the power supply, but has that split socket on the other side that won’t match up with the power connector on the board.
I’ve probably over explained it and am over thinking it maybe. I know there’s cables to connect SATA to the two six pins on the graphics card, but I was under the impression I needed all those available sockets under SATA for my powered risers.
I guess that’s my sticking point and why you didn’t have an issue - you don’t run powered risers do you?
EDIT: oh for f- there’s six sockets for sata there not 4. There’s probably plenty of room. Checking.

I have the same mobo, and psu and I use the on in pic 4.

I was totally sweating because those pins don’t match exactly. Took it home to organize and went ahead and used that split wire and it worked fine. Thanks.

Haha. Oh geez.
Okay, I’ve been offline for the past 2 working days because something happened where I was tweaking the cgminer config file (honest. swear to [i]god[/i] that’s all I touched.) and the next thing I know the board was rejecting the USB stick. I tried fixing it with no luck ended up giving up and just reinstalling and reconfiguring everything. THAT’S never going to happen again, losing so much time that could’ve been spent mining, so I’m going to make a disk image of the OS that I can replicate the next time I pull the machine down, which should be tonight.
Have you two noticed anything where when booting up the machine says to plug in something bootable, even though one reboot ago the stick was working fine? All I changed was stuff in my cgminer startup script, copying the settings in rgfii’s build.
-
Can’t say that I have but then I never had much luck with booting from USB so prefer to stick with the standard hdd (SSD).
Sounds like you somehow corrupted the USB sticks boot sectors. Did you remove the USB key?
-
I have 20GB SATAs from old Xbox encasings laying around all over the place. Next time this thing goes down I’ll have one of those prepped. I just figured I’d turn off power to everything but USB (no sata, no USB3.0, no 1394, etc.) but it really makes no difference in the grand scheme of things.
And yesterday after rebooting my machine it would get right to work but this morning it booted and went into GRUB so apparently it’s not been doing crap for the entirety of the day. Ugh. Going to go find a way to knock that crap off now.*
Nevermind, it’s going right to desktop again now.

Okay, everything is going great. So great I’m scared to screw with it, BUT:
1. I’m seeing results in the hardware comparison ranging between 600-700, but I’m topping out at 570 per card by:
Intensity = 20
Engine = 1050
Memory =1400
Powertune = 20
And the little button pressed on the top (looked like some others had theirs pressed, even with those settings put in by hand it didn’t kick to 570 unless the button was pushed - or does it do absolutely nothing?)
I see other metrics like shading, thread concurrency, etc. but I really want to know what that stuff [i]means[/i] before I start randomly plugging in there. What’s the baseline config file for cgminer linux that I can tweak instead of starting with a blank page? Is there any chance someone can paste up one they’ve used for this similar hardware? It’d be nice to have a normal config file anyway; I’m putting all this stuff in by hand each time I boot up in the morning.2. …can I run 6 7950s off this board and power supply? It’s physically possible, but [i]should I[/i]?

[/quote]I’ll address the second point first… Even that monster supply will not run 6 7950’s. Especially when OC’d.
As for point 1, i’m writing up a tuning guide but it a looong way from ready. The little button you speak of has me confused, do you mean the bios switch that switches between BIOS 1 and Bios 2? If so it will do nothing unless you have flashed a new firmware to your card.
Shaders are the number of shaders your card has. For your 7950 its 1792. That’s a fixed number and if left blank CG should autodetect. As for the rest of the settings, have a look here… [url=https://github.com/ckolivas/cgminer/blob/master/SCRYPT-README]https://github.com/ckolivas/cgminer/blob/master/SCRYPT-README[/url]. I think it explains everything nicely but i’m writing a new guide to elaborate and simplify it a bit.

[/quote]VERY good point! See the sticky at the top of this board for a tutorial on making your own if you haven’t already got some.

if he use 6 its doomed to become barbeque, ive tried both on amd and intel platform, both 68 and 77 chipset++
It gets burned to a crisp. and waranty do not cover it (ive tried), which is kinda stupid since its really a design flaw when the mobo has enough pci-e connectors. -

So don’t even push 5, just stick with 4?

This little blue light off the rgfii’s rig, there’s one per card:
https://forum.feathercoin.com/index.php?topic=2635.0
I did not see any documentation for them.

Okay, thanks, I’ll dive right in reading that.

5 would most likely work for a while… but in the long run things will start to happen. if you use 4 your within limits for 24/365 ;D
If you set thread-concurrency, shaders settings doesnt matter, just look at my config where i put shaders 0.that little blue button is as far as i know the sapphire bost button (for preclocked bios), but i do not use it. i just see wasted power from the leds=P set exactly the gpu/mem clock i want in cgminer.
i have 15 of those 7950’s without the led at 650khash and they run really well without any hitch, also run em with seasonic x1250 (what an wonderfull psu!) -

[/quote]Copied your settings, removing the failover bits and changing account and pool info where appropriate, rebooted system, now there’s apparently “no screen to be attached matching cgm”. Googled around a bit and tried “alias nrbcm=‘screen -d -r cgm || miner-launcher.sh’” but that didn’t work.
Hard rebooting now -nope. Still nothing.
HOLY SHIT removed the api stuff and it the fans just kicked on and it sounds like a tornado alarm going off in here
Running around 650 a piece and the coolest I’ve ever seen them.
-
85% fan speed is high, but seems to be the sweetspot for me at least.
Stable as HELL, and just about cool enough that nothing overheats, even during the day with 30degrees outside and 40 in the room. (cards are around 80degres)
