Can I ask how you are getting 4.5 MHz?

290's do around 800-850 max "ish" x 3
7900 - 1500 Max "ish" probably less

That total at max 4 MHz

Course, it's all averages so is definitely hit and miss from time to time.

My 290's do around 880 average and each core on the 7990 is doing around 770. My rig is off at the moment as we're sorting the cellar out and making a proper 'mining area' but when it's back on I'll get the exact config I am using.

Also worth mentioning that my current setup has been allowed to churn and burn without me giving much thought to heat. The rig does get really hot (the 7990 was running about 95-100 all night) so a lot of people would sacrifice the extra hash because of the heat.
 
Sweet Jesus! I might look into this bitcoin (or dogecoin lol) mining.

One question though, does that processor bottleneck those cards? Or will a high-end processor be better?

CPU has absolutely no impact on mining at all. It's not like gaming where the CPU compliments the GPU - the CPU simply allows the computer to be turned on.

I advise get the cheapest HDD, CPU and Memory, a standard Motherboard that will give you as many ports as you need (six in my case) and the best PSU you can afford.

Thanks wndsr! Might use a similar build to yours, since you've pretty much nailed it :D

A lot of people say I'm crazy getting into this now, but I'd rather take the chance with the possibility of making money from it (and I think it's a very strong possibility too).

Maybe start off with just a few cards then expand depending on how you feel. I'm well known for testing the water with both feet :p

That rig is madness mate. Are you getting rid of the 7990 and using the same mobo/CPU for those 3 x 280s? Is it even possible?

Aye that's right - the 7990 sale has funded the 280X's. They'll all be on risers and the board shouldn't have a problem recognising six cards providing they're all connected properly and the risers are powered.

Only one way to find out though I reckon ;)
 
Time for a quick update.

The past day or two hasn't been very good as I have been struggling to get my PCI risers to work properly with my motherboard. I did however buy 3 more GPU's - R9 280 by MSI so I will get them fitted shortly.

After extensive testing I have concluded that my botherboard is not designed to have all PCI ports running at the same time, so lanes become disabled if a component is occupying another one on the board.

I've bought myself a new motherboard specifically designed for Mining so I shouldn't be having any more problems. I still think the primary GPU needs to be on a full length (PCIx16) riser for it to work so I have bought one of them.

I now also have a wooden frame to lift the cards on top of the case.

Father Wndsr helped with this one as I'm awful at DIY type stuff.

I've also put an old desk up in the cellar so the mine has it's own little area now, rather than it balancing on the top of a book shelf.

Temperatures now are phenomenally better too. No card has yet gone over 70 degrees and they've been running full load for over 12 hours now. Very impressed with them.

Will update some more tomorrow and remember to take more photos :D
 
Just wait until I've got all six cards in tomorrow, then it will look pretty damn awesome!

I have indeed yeah. Wasn't "planned" this way though - basically by mining a coin and flogging it on eBay haha.

Thats not good, I used your shopping list rather than look into it myself, how many cards were you able to get running on it before the lanes became disabled? I'm hoping 4 because I was planning on purchasing another 2 280x for mine.

*edit*
Derp, you were running 4, 2 more 280x ordered!

This is looking sick Wndsr, wish I had a cellar :D

Once it is full set-up how much time do you think you are going to have to dedicate to this to make a profit? I remember you saying on TS its using up allot of your time.
 
Quick question regarding the Gigabyte Gigabyte F2A85X-UP4

The expansion slots are noted as:

"1 x PCI Express x16 slot
1 x PCI Express x16 slot, running at x8
1 x PCI Express x16 slot, running at x4
3x PCI Express x1 slot
1x PCI slots"

I'm wondering if the speeds affect overall performance of the graphics cards at all, and if they do, did you do some tweaking to get the most out of them?
 
Thanks for your time the other night wndsr, going to look at other mining clients to see if they will workon the m18x for now :)

I don't want to splash out on new hardware just yet although I do have a spare complete PC minus GPU. So may go down that route instead lol.

Get some more pics up when you get that new mobo in place.
