Not bad pricing baring in mind what you make back and save on the heating bills What people are forgetting here is OcUK are a business.

Definitely not forgetting OcUK are a business, heck I wouldn't ever expect them to sell anything for less than cost price.

Stop letting the fact they need to turn a profit get in the way of a good witch hunt

if people want to buy these and jump on the mining bandwagon then let them.

you guys are just jelly all the noobs will be taking a share of the coins mined and raising the difficulty level sooner rather than later.
personally I wouldn't risk it but if others think the boom will continue long enough then let them risk their own monies.

Nice gimmick but ultimately useless for mining.

Bitcoin - CPU/GPU mining became redundant a long time ago and only ASIC's cut it now.

Litecoin - Even with my rig pushing out over 1200 Kh/s it's still not economically viable for me.

You must pay a crazy amount for power then!

So many people saying jump on the wagon and others saying it won't be profitable so confusing.

Would it not be safer to source 2nd hand pc with a decent mobo with 3 or 4 pci express slots and just slap in 3-4 Radeon 7950s/7970s ?

i just do economy 7 mining lol 1130pm-630am instead of using my office storage heater uses less power and makes money. I get maybe £100/month and the elec goes up by around £21. It helps to pay for new games. Wish I'd kept my 4 7970s now tho seeing they get almost 6 times this.

Thats why im quite suprised these are shipping with bronze and gold PSUs when they have recently got a load of superflower platinum PSU's in!

What is the best radeon card considering the 7990s are not viable in terms of cost and effectiveness ?

It would increase prices. This is interesting.

[waso_dude]

the base system with three 290 in there overclocked to 290x speeds would cost £1500

if you mine litecoins you would get this back in around 3 months after power costs making the PC effectively free...

food for thought.

and in 1month difficultys get harder. Its fairer to say this is about 6months to a year 24/7 mining to get this back.

Absolutely YES! Second hand MOBO/CPU with low power and throw 4 even 5 gcards in it. No case but make sure it's safe. 4GB 1333MHz RAM will do

AMD CPU - Quad core
AMD mobo supporting four PCIE x16 slots
4GB 133Mhz/1660MHz RAM
1200W PSU - absolutely necessary
4 cards

Could even possibly use a 16x-1x riser and add another two cards as long as your PSU supports the load. Remember mining is 99% load on the GPUs or not worth it

I do appreciate OCUK are trying to make things easy for their customers and some will buy. Good on them.

7950s offer best bang for buck but good luck getting them

thx I thought this sounded a bit like ocuk sales pitch lol

was thinking 3x290s (unlocked to X cards) for around 1.5k and getting the money back after 3 months is to good to be true, and you just confirmed its actually 6 months which sounds perhaps more right!

Yeah can see why many go AMD platform and cheaper prices... 7950s/7970s going for £160-200 on mm all the time.... but yeah still have to weigh up all these options.

Was thinking rather then wasting 1-.1.5k on a highend pc which I would not use half the time put it into a PC with 3x290s and leave it 24/7 mining but still unsure if returns will be worth it after a month or 2... if I had believed the ocuk sales pitch earlier of getting back 1.5k with 3x 290s in 3 months time I may have just placed the order !

No you wouldn't, the more they are mined the harder they are to mine, it is an exponential guesstimate, in 3 months time it will take a lot longer to mine a coin than it will now.

 

[86JR]

What I will say though is this might be a safer investment.

If you bought litecoin now at £30? you could buy 50 of them for £1500. Maybe it will become the next bitcoin..£1200 a pop = £60,000, however selling them is risky, places like mtgox have been ripping people off left right and centre when bitcoin peaked in value, so you might have litecoins with a value of £60k but worth nothing.

However if it goes the other way...drops to £1, that's a £1450 loss.

Atleast with the OCUK way you have £1200ish of PC components left to sell, so only circa £300 loss, or a complete gaming PC to use, you don't need 3 290x's to game so could sell two for what, £300, £600 in total, pc cost you £800.

But then you have to compute £100 of power charge a month x "3 months" = £300.

Honestly I have £15k sitting in an account right now it has been there since bitcoin was £15, and I have not bought, did I kick myself when it hit £1200? Yeah, until I realised that everyone selling at that point was getting locked out by the exchanges and was glad that I wasn't stuck with £1.2m worth of worthless online currency.

**** PLEASE NOTE - WE STRONGLY RECOMMEND THAT THE GRAPHICS CARD FANS ARE MANUALLY SET TO 100% WHEN MINING - GRAPHICS CARD WARRANTY IS NOT VALID OTHERWISE ****

Two problems here.

#1 You won't know what percentage fan speed was being used when the card died so it is pointless stating that not having the fans at 100% will invalidate warranty. The recommendation is solid enough though in essence.

#2 An OcUK rep commented on the Facebook post corresponding to this announcement saying "you could probably get away with 60% fan speed to be honest"

Also as a side note, I think that using 290/290X's with reference coolers for mining or folding is ludicrous and makes precisely zero sense.

When you work in retail its simply known as paperwork

but good point about the 290s.... with custom and better heatsink/coolers due jan/feb it would be better to get those instead.

I'm about to buy 3 x R9 290 cards for a mining rig. It will go in the cellar so will be very cold down there and I intend to have plenty of extra fans above the cards sucking the hot air out from between them. Do you think this will still be an issue?

Can investigate better cooling if required but not really wanting to start replacing the coolers on them.

 

[Akagi]

I'm just concerned that leaving the cards working under intense load 24/7 - taking into account that the nature of the design means they run at around 90 degrees as a single card (let alone when there are several sandwiched together) - might cause them damage and will eventually lead to failure.

As said above, I would personally wait for the non-reference cooled models or even get them under water.

 

[silversurfer]

Should run 80c or less with a case at normal room temp. I would budget in half a dozen 120mm fans at least as optional; maybe thermistor controlled to ensure the case is in no way building up heat over the hours.
Blow > suck
The aftermarket stuff is trying to compensate for failings elsewhere or just make it quieter, a cellar makes that simple then.

Worst case I had was tiny jam packed with 6 IDE drives, case temp rose to 50c so it was hot to touch All my own fault, max the airflow and the cards will be fine. Problem is you do that right and its a 80c 300w fanheater, you wont be needing central heating on
