Confirmed that VBE7 does work with 280x cards. Flashed half a dozen Gigabyte 280xs this week, and they're all hashing @ 725KH/s @ 1.019V. Dropped consumption for a 5 GPU rig frim 1450W to 1250W, and lower temps as well. Test on one going lower and lower, and then flashing the others only took me ~5-10 minutes per card.
Hey bro is your 1.019 the VBE7 setting or what GPUZ reports? I'm using Linux, so I can't tell you what GPUz reports. I do know that the 1.019V is what VBE7 reports, and then after the flash CGMiner reports the same value. Also, power consumption dropped by ~200W for the 5 GPU rig, and temps went down a good bit as well, so I'm pretty confident that it worked.  Very nice  |

not to worry guys, everything will be fine
|

We are up and running again, that's what counts. Good job guys on the quick fix  |
|
|

you guys are right, my mistake. I didn't see the new blockchain download link on the main page. I was just re-downloading the wallet, deleting the old chain files and re-syncing. Everything works perfect. |
|
|
|
|
Actually I'm getting the same warning. I redownloaded the wallet twice and replaced everything twice
it says downloaded 3426 of 3530 blocks 97.05% done

yo batman brainstorming again maybe the fork is a great opportunity for a full relaunch? change the code, make it instamine-protected, remove the x3,x2 blocks and stuff like that, obfuscate the rewards part of the code so no one will know when it will be best to mine to avoid insta miners, maybe add some additional stuff that you fought about in this couple of days and restart it all of course that if everyone here agrees are you out of your mind? I fully expect this coin to hit the exchanges. If we start over I'd have lost hundreds of dollars I could have made mining a different coin. |

keep the one from n0nplusultra |

When it forks does that mean all coins we find during that time will be lost?

A lot of guys here have thousands of watts with thick cords coming from all rooms in the house running in their bedrooms powering rigs at the foot of their beds sucking massive power/dishing out enough heat to cook sausages. A typical house lamp is more hazardous than your USB miner. LoL and no the cold won't hurt it. there is a happy medium with computers and temps but for example it has been -18 degrees F outside and I've the window wide open exchanging cold air with my rigs and they have been very happy campers. my printer on the other hand wasn't so happy. the damn ink froze.  |

Does anyone know the official limit for for the pwm fan headers on these mobos?
I always thought they were somewhere in the range of 10watts but I hooked up two 15 watt fans for a total of 30watts with all the power coming from the header and they completely maxed out 100% at over 5600rpm each. These were the chassis headers, not the cpu.
If the header can deliver the power is it all good? Or would it eventually fry out somewhere? I mean it's only 30 watts and the pins aren't that small.
I am wondering because I need to hookup some powerful fans and I want to have control of them via software remotely from any location in the world. vs getting fan controllers.
Thoughts?
Also what about the video card PWM fan header, what is the voltage output on those?
and before anyone asks, yes I am running 120v regular fans for cooling. my questions here are related to something else.

GPUZ reports 1.039-1.078 for vddc
as soon as cards hit 73-74C they start bouncing from 64-99% usage and cuts hashrate from 735 to 500's for each card. Pisses me off!
There's like 10 different threads on here of people with this issue. You all need to get your asses in here and lets figure this out.
Before anyone tells me to try different cooling, I have a bunch of 280x in a cold room that run perfectly fast at 60% fan speed. The cards that are throttling are in the living room, for now. Which is besides the point because once summer hits it's going to be hard to keep all these cards under 73C.
SAPPHIRE RELEASE A DAMN FIX FOR THIS or we will ALL SWITCH TO MSI
Oh and I tried default voltage with powertune +20 it makes no difference. It's not a power issue it's a heat issue. PSU's are all ample power Corsair & Seasonic Gold's.

Come on with everyone having this issue how has nobody solved this yet
|
|
|
|

The Toxic 280x can run 800kh/s. voltage is locked though, have to tweak the bios with vbe7
|
|
|
|
|
maybe a bandwidth issue. I would try running 1x risers on all of them
also check gpu usage in afterburner and make sure it's constant and not throttling up and down.

This is just out of pure curiosity but is 2 cores 3gb ram really all you need to run a pool with 100,000kh? What about internet bandwidth, how much upstream is needed per x given amount of miners.
Lets say a person wanted to set up a pool for 1 coin. Knowing that cloud/amazon/etc is of course better, but just out of curiosity for hardware requirements how many miners and kh could the following hardware support at over 90% efficiency;
3770k 4/8
16GB-32GB RAM
256GB SSD
And then using bandwith of 30Mbps downstream with 4Mbps upstream, by how much would that connection reduce those numbers, or is that connection good enough.

always sign up for multiple pools on launch. 1 out of the 3 I picked is working, the other 2 are dead
