Thank you all for the replies.

After installing a case fan, the temperature only goes to 83C if I run it without flags.
Running with -v -w 256 (or 128) gives me a lower hashrate, but also a lower temperature (79C).
Haven't tweaked other settings yet.
Is the CCC power control as good as undervolting with Afterburner or Trixx?

It only goes to 92C when mining. The idle temperature isn't high at all.

It's a brand new card. Haven't tweaked anything yet.
I have a micro-ATX case with only one case fan, so the air flow isn't the best.

Hi all,

I've got a new Powercolor 7870 Tahiti. I got around 425 Mhash/s using GUIMiner, but the temperature went up to 92C.
I am thinking maybe I should undervolt and underclock to keep it below 80C.
I have no prior experience in over/underclocking.
Can someone please give me some advice?

Thanks,
Arthur

I have been using GUIMiner for a while. I've heard that DiabloMiner is kernel optimized for GCN.
Can someone tell me how to mine on stratum with DiabloMiner?
I've tried:
DiabloMiner-Windows.exe -l http://worker:password@stratum.bitcoin.cz:3333
and I kept getting ERROR: Cannot connect to stratum.bitcoin.cz: Unexpected end of file from server
I have been doing some Googling and still couldn't find the correct command.
Can somebody please help me out?

420/360 mhash is a 17% increase.
7870 is about £180, and 7850 is about £150, which is a 20% increase.
But factoring in other costs, the % difference in price will be lower than that.

I am thinking of building a new rig for mining, but don't want to spend too much.
I am deciding between a 7850 or 7870. Of course the 7870 is faster, but is the extra cost worth it?
On a side note, it'll be used for gaming as well. Would an i3 3220 CPU be enough? (My other option would be AMD FX 6300, but i3 is slightly cheaper with a cheaper B75 motherboard, with a lower power consumption)

Thanks for your time reading my post. =]

I couldn't find that task again.
I tried the website again with some other tasks and found the payout quite good compared to other bitcoin sites.
Thanks. =]

Chrome. I have a screen that is supposed to be 1920*1080 set to 1600*900.

I find bitcoinget unusable for me. It forces everything into a small window in the middle. Sometimes, the information I need is just outside the window and I can't click onto it. Hence, I can't finish the task.

http://dailybitcoins.org/index.php <-this one. refresh until you get 0.00010 or higher
For most other sites, I find mining with my laptop more profitable LOL

It's not only the Americans that are using it. Unless all governments act together against Bitcoins, there shouldn't be too much of an effect.

Thanks. The fees seem more reasonable for btc-e.com

I clicked on namecoind.exe, a console pops up. A few seconds later, the console just disappeared and nothing happened....

Vircurex seems to charge a huge amount on withdrawal....
My whole Bitcoin wallet consists of 0.0002 BTC....

I am mining in Slush's pool, and read that I can get "free" Namecoins if I can provide an address.
After doing some Googling, there are posts recommending registering an account on Crypto X Change, but the site has been closed down long ago.
The default Namecoin client doesn't seem to be very user friendly.
Can anyone advice me on the best way to get started with Namecoin?

I am considering getting a new PC for mining, but I am not sure if it will still be a good investment. (Since now everyone is doing it, the mining would be more competitive and harder.)
It's also a pain trying to get a decent PC in the UK. I don't trust online companies enough to buy a PC and have it delivered. And I simply can't find decent enough PCs in chain computer shops (e.g. PC world).
If I were to get a new PC with Ati card, I am considering this one: http://www.dinopc.com/shop/pc/-b-NEW-b-Raider-AMD-X6-6300-94p1640.htm

For now, I can't just change the graphics card in my laptop. My bills are included in the rent, and my laptop keeps the room warm in this cold weather. LOL

I've been using the default OpenCL miner in guiminer, and it went up to 26-27 Mhash/s
I've now read about rpcminer-cuda and I am using that instead, but it only gets to 24.6Mhas/s
Though I temperatures are lower using rpcminer-cuda compared to the default OpenCL miner
Is this usual? Should I keep on using rpcminer-cuda? Or switch back to the default miner?

I am new to Bitcoin. Trying to mine with my laptop. =P (My bills are included in rent, plus it helps warm my room in the cold weather.)
I wish I knew about this earlier (like everyone else lol).
I don't really looking to earn money. It's more about seeing numbers go up. If you play any MMO or loot based dungeon crawlers, you know what I mean.
