i was thinking something along those lines... and I do too!

Yeah... i noticed that...  too. the first two hit saying 600 shares... and I mean in like 11 hours, I pump way more then 1200 shares.. so i was worried... as it stands, i think that brought it up to where it should be.. i am wondering if it wasa casualty of the work they are doing, so an arbitrary amount of shares were allocated. Hmm.. Just hope its smoothed out now. I was worried, not hitting a block in that long.

Strange.... two blocks found, but shares seem way off... and times are strange...

Is the site reporting blocks and shares accurately atm?

Thx

Ahhh... Seen... Hmm but what do the 6990's retail around your neck of the woods? I'd imagine a cheap sempron and 3 5850's in a box with board, ram and PS could be had for the same price as 1 6990... although, the 6990 would possibly be more power efficient.

What miner and flags do you use with your 6950? what sort of yield do you get? I am with GUIMiner and default poc and getting 310-320 Mhash/s.. but feel like I should be able to eek out a bit more. Also, for me the -v -w128 decreases my throughput... but worked wonders on my 58xx.

Edit: Had to price check 6990's... they aren't as high as I thought up here around me.. so my bad.. i was placing them in the $800 arena.. when you can get em for low 7's... (my bad)

No point in a 6990 unless you don't have the slots for crossfire.. 2 6970's will out mine a 6990, and save you a chunk of change to boot. But if you don't have the PCIE slots.. then it's probably about the same as a new board and 2 6970s... depending upon your cpu.
Heck.. Depending on prevailing 6990 prices, and the number of PCIE 16x (physical) slots on your mobo, 3 could be had for near the same price.. then your mining at ~150% a 6990... Depending upon how the miners scale when your throwing that much power around...

Or as you already have a 6950.. perhaps 3 of them... You know... now that i think of it.. i really ought to see what I have available for useable PCIE slots... hmmm...

My second 6950 should be arriving in a couple days... Then I get a crossfire rig as well as a 660ish MHash/s Miner... add my 5850 in my livingroom htpc.. and I might touch 1Ghash/s

grin

What are you running for voltage on that? have you changed it over stock? or does it come higher then stock from ASUS? My 6950 XFX 1 GB runs a paltry 71 degrees at 840, with fan at like 85% If I drop fan down to mid to high 50s then temp hits 80ish... Perhaps you've got a bit too much voltage there?

Yeah, so far it's been going really well.. even though i don't have all that much hardware to mine with... i am only pulling like 550MHashes/s.. maybe closer to 600... But my new Video card is coming in the mail soon

Interesting... Do you remember your scores before and after? also, i am running win 7 so i assume I may have a lower MHash/s then you will... However, one thing I hadn't found so far, is where my version of ATI SDK would be found. I couldn't find it in the Catalyst properties, and so i assume since I don't seem to glean the benefits of some of the various flags, that i am running 2.4... Also, I have heard that dfferent miners can yield better results for me, but so far, no kernel or miner I have tried through GUIMiner has been better then no flags and default Poc...

Can anyone chime in with some better windows results then 310-315Mhashs/s?

Willing to try a different miner if need be to achieve.

Also: does lowering memory clocks achieve anything other then dropping power consumption slightly?

Thanks All.

As would I... In fact, you figure since Dailytech 'scooped' the rest of the mainstream tech press with their stories on BTC (however laughable Jason Mick is) that their 'well respected cousin 'Anandtech' would write a review and bench GPUs on BTC Mining. Who knows, perhaps someone is working on it as we speak.

But yeah, Llano hits the GPU limited market right where it needs it, in the mobile sector. Just think, had they been able to get decent yields at 45nm... we'd have been using them for near a year already. Although, they would've resembled the first phenoms... Far to dense for the then current SOI  fabrication. Even iNtel waited till 45nm to do a monolithic Quad.

I tried that... and it doesn't.

It does on my HD 5850... but HD5xxx hardware uses a 5 wide execution unit, whereas Cayman (HD69xx) uses a 4 wide execution unit... I found it actually dropped me by about 40MHashes/s with GUIMiner and Poclbm...

So i am thinking that the boost i saw on my HD5850 was related to the wider architecture that AMD dropped with its 69xx series... Thanks though, that's one of the reasons i posted here... That and to give newbies something to post about for 5 hours Consider it a captive audience :p

Have you tried it on your cards? Do you have a 69xx?

Thanks.

Hmmmm... this block seems to be taking a long time... Or is it just a delay in posting result?

Also in regards to stale/invalid shares... I am in Canada, on the West Coast, and I have averaged less then 1/2% of stale/invalid... so I don't think its quite a distance or location thing.

Hey there,

Curious about the miner you use, clocks on your card, and which flags you use... looking to see if i have maxed my Cayman out:


XFX 6950 1GB running: GUIminer v2011-06-09 w/default poclbm / 840 Mhz GPU / no extra flags -- 305-315 MHashes / s

Anyone else out there? I should be receiving my 2nd 6950 in a few days so better settings (if available) x 2 then.

Heck buy AMD stock for zacate, ontario, llano, etc. Poor guys can't fab enough of the first two, and the later is going to completely change one's view of AMD and mobile yet again... no more 2.5hr batteries in AMD notebooks. (thank pete).

Anyone know if someone's tried to mine on a c50, or e350? It should via the DX11 GPU put perhaps an i7 to shame... think of that.. mining on a 9w c-50 and pulling more MHashes/s then a mighty i7..

Mostly true... except if you click all, then read 20-30 pages of posts... it times out while you are doing so... then you go to the next thread.. and lo and behold, you weren't active for a lot of the time you were reading said 30 page thread... Lesson to self... click through page by page so the script counts you as present.

Exactly... that CPU mining can use 100w/hr easily... more if its a 4-6core behemoth... not a very efficient way to mine. It's why Botnets tend not to have the power to challenge 'honest' systems in generating current Blocks / etc. The systems tend not to have the gpgpu HP.

Good to know... US bank as originator?

Thanks.
i am curious if Canadian Banks would be slower.

Any one with experience transferring from a Canadian bank to Dwolla?

There are other methods that would effect the value of BTC far more negatively then by trying to outmine everyone else, or utilizing some of the methods mentioned above to attempt to destroy it...

1. Attack liquidity... If you cannot get global currencies in or out easily.. as in w/o requiring many layers of laundering, or tech savy above a certain level... then it kills the useability by merchants. In the end run merchants / service providers/ etc require the ability to pay their workers / suppliers / costs / etc with BTC to see it flourish as more then a side game.

2. Attack the pools. far more easily then attempting to leverage standard CPU based compute power to out mine the legions of GPU using gamers that will be / are mining BTC would be to attack the pools and exchanges with DDOS attacks. These would greatly hurt the ability to mine, and to continually regenerate the encrypted transaction logs required to sustain the currency / add bitcoins / protect against hijacking or counterfeiting.



Also, watch for IRS audits in the cases where major coin (pun intended) is made from BTC speculating, as in the US I believe they can tax you for any money made, even that made outside the US, unless you have offsetting tax credits from paying foreign taxes. Thus they can tax you if they can find it. And if your silly enough to spend the "insert global currency here" in a traceable manner, and the IRS decides its outside of your means, they will audit you, and audit you again, and again if they really feel you are gaining money that has not been taxed. Again, this brings us nack to liquidity. The Porsche 911 you buy with BTC isn't a traceable transaction... until you go to register and license said car. Then the IRS might be interested to know where the money came from, when you make $14/hr at your day job...

Very neat... so every kwh you use costs you the 44c.... hmm.. does your closest neighbor have panels? Run an extension cable and just pay your portion of their (perhaps panel free) electricity bill?

The trade off to the 2-4MH/s part is that your power consumption jumps even more. You may want to see what your power consumption is with and without the CPU going balls out... Becaue 2-4MH/s at an extra .1kwhs adds up over months of time... especially considering a GPU is far more efficient (6xxx and 5xxx) per kwh.
