Congrats on your first rig! a few tips now that you got your feet wet :D

Your RPM per fan is way to high (3600 rpm!). While the temperature is at the range where you want it to be (70), it might be better to use an external fan to make the video card work less hard.

Then when you feel brave, flash a new bios and cut power consumption by 15%

Here something you should aim for :D msg me if you need any help getting to it.

Well finally found the time to learn to flash my GPU bios’s and undervolt them. First couple attempts I had cgminer crash after they cranked up. I started to low on the voltage. They seem to work fine at 1.125V. Fan rpm down in the 2k range, dropped power tune to 0 on both cards and everything seems to be working great. Lowered the drain at the wall by almost 100watts too. Here is a screen shot of my cgminer numbers after 24 hours non stop hashing o the undervolted setup:

Thanks for the help and advice. Will post pictures of my new rig frames I have been building today too.

peace,

PS: How do I get cgminer to display the rejects as a % that is pretty cool. Also what do the WU:579.1 /m number tell me??

i have 4 gb of ram, i was going to test it on windows 7 because i was running windows 8 on the rig now. But i got sick today so i haven’t had time to do it yet

Im pretty happy with my freevnc, it just works. and don’t have the number of computers limitation as the team viewer free version.
I also figured out that its not the card that is causing the mockup in regards to need of dummy.
It seems its the mobo that is causing the headache for some reasons (was amazed when i moved the card to another mobo i had no need for the dummies), exact same windows install/amd drivers etc.
[/quote]

Few questions:
1. What motherborad is that?
2. If I have a rig with 4 GPUs, do I need dummy plug for all of them or just for one?
3. If I actually have a monitor connected to one GPU, do I need dummy plugs at all?
[/quote]

1. uuuuuhm, i have 8 rigs all with different mobos, its like russian rullett if you need it or not. for example the one you really do not need on is a bitch to get working several cards on in general
2. if you get a setup where this is a problem you will need a dummy plug in each card, (not including the “main card” if you have an monitor plugged in)
3. If you have an monitor connected to one GPU you will get full speed on that GPU, the rest will run idle at around 80khash, until you put dummie plugs in em.

If you dont have the setup yet, go to ebay and buy a small stack of DVI-I and a small pile of 68 or 75ohms resistors. then in case it becomes an issue at least you have the solution ready,
also it cost next to nothing for those things, think i paid like 10GBP for 20x DVI-I with matching resistors including shipping.

awesome! are you planning to support this JSON API over long term?
I think I might be integrating it to an upcoming project that I am working on.
[/quote]

Yep, the JSON output will be there :-)
Which attributes of the JSON will you be using ?

I will be adding more coins to it though but not all of them like on coinwarz.
[/quote]

Coin profitability, well… just wondering because coinwarz does charge a sum after 500 API calls every 24 hours. :P
Having a server to cache the result and redistribute will be the best ;)

Too many factors could be at play here, first step would be to do a clean install instead of copying the directory from one PC to another…

I can’t find the original post asking about this, but I have just found this on another forum

[quote]Okay so I figured I’d let everyone here know, sgminer 4.0.0 (cgminer 3.7.2 fork) has added support for a comma-seperated gpu-threads value. This should make it possible to run diff model cards all from the same instance of sgminer. This script is obsolete (sorry OP). Sgminer is scrypt only BTW. Also included in this great fork is many fixes to make the R9 290s stable! Fantastic stuff.[/quote]

I’ll dig it up this week and get it installed on a rig and see if it does all it claims.

I’ll keep you posted

UM

I’m running it on one of my rigs, windows, no difference to CGMiner 3.7.2 IMHO, Hash rates and WU identical…

Very good info, rep+

heh, I’m still mining on a single 7850.
[/quote]

I’m on my single R9 270 until I get around to using risers to go dual 270’s.

[quote author=Tuck Fheman link=topic=7214.msg55783#msg55783 date=1390959152]
Due to my low hashrate, my strategy has always been to get in early (0-1 day) and hold all mined coins.
When I have no new coins to mine, I come back to FTC for my 4-7 per day.
[/quote]

That is exactly what I’m doing. With the exception if the fact that I haven’t been mining for a week now. Gonna go pick up my rig today… Although, I’m not sure if my usb sick will work in bamt smos.

For now I might just have to use my spare R9 that’s in my mates gaming rig. Swapped out the nVidia. It’s mining through guiminer and I can’t get it to go faster than 430khash/s. But heck, hash is hash right?

EDIT Posted in the section sorry guys

The $/khash is too high for this, and resale value is very low once it’s outdated… its worth it only if you got expensive electricity. 2nd gen will probably be much better, if the algos might be changed to fight that…

How do you voltage mod - as I have a Giga 280x’s Rev2 card also

[/quote]

1: Download bios from card with atiflash
2: change voltages with VBE program
3: flash bios back with atiflash

It’s too noisy and the only place for the machine is in family space.

I have two of the exact same rigs I built with the same setup… Both are having the same exact issue, so it’s not a defect in the hardware, something is up with the OS…
If anyone can help it would be much appreciated

Everything seems to be back to normal at the moment:

time to block = 5h 34 minutes
Time between the last two blocks found: ~ 5 hours 15 minutes

congratulations :)

Could you add a [solved] at the beginning of the headline?

Your title is a bit misleading - Moved to Mining.

Finally realized that guiminer uses gpu and I was trying to do cpu mining. I managed to get cpuminer up and running. Yay! Thanks anyway. :-)
