2  Bitcoin / Mining / Need some help please! on: June 02, 2011, 02:37:31 AM
First problem: I am having some weird bitcoin problem, I reinstalled (downloaded newested bitcoin from

Second problem: I get "Verification failed, check hardware!" for my GPUMINER. Why does it do this?


win 7 64 bit
6970 ATI PowerColor (new card i just got that gives me this error)
quad core 2/4 ghz
psu  750w

880 core clock
1375 downed to 1200 (lowering to 800 only decrements temp for me by 1-4 c) and makes pc way lagger

-f0 -d0 -w 128 are my flags when im sleeping i put it to -f60 when awake

for now my problem 2 i use the console now and coded a program which kills poclbm after some time and then runs it again like every 30 mins.
3  Bitcoin / Mining / Is this normal? Just want to confirm. on: May 31, 2011, 03:39:19 PM
Setting: Value when sleeping (Value when awake)

Voltage: 1.2
Fan: 50% (55%)
Clock: 925
Frames: 0 (60)
Memory: 800

-v slowed my pc
-s0.01 lowered my average hash rate by only 1-3MH/s, but its a good feature to use i guess when sleeping but I don't use it I might later on
-w128 worked wonders
-w64 froze my pc about 2 times when i did stuff on my pc
-f 0 works good and doesn't lag my pc too much i can still go on forums, etc.
-f 60 works better when i want to use my pc

Temp never go above 74, but its on [71-72] average.

I was wondering why when I went to youtube my computer would freeze also if someone could be so kind.
4  Bitcoin / Mining / Just got a 6970 ATI powercooler, any suggestions on settings? on: May 31, 2011, 02:43:02 AM
Should I use GUI miner/poclbm or phoneix, I don't want to overclock my gpu too much cause I want to run it 24/7 and I don't want to hear my fan noise when Im sleeping (I sleep 1 room away and I keep the computer room closed and yes it has a return duct for intake). Hope someone can help me out.

Not too sure about that PSU, and why not get a 3 slot mobo so in the future you can hook up another GPU?

Good luck.

450watts is what you draw from the wall then it has to be converted to dc power considerable power loss between the 2. Consider the following any usb deices and so forth take power another thing to look into is was there a beep when ur card failed? try over clocking till your computer shuts off. Listen to the beep patern from the mother board watch how many long and short bees then google it. Chance is that its lack of power could be other stuff thogh good luck

not sure if buying BTCs for 5000$ would be better investment.
If you buy the hardware and bitcoin's value should crash, you still have the hardware Wink

yes i agree to this, but you should still invest in btc like $200 to $500 if you can afford it.
9  Bitcoin / Mining / Re: YouTube Video: Bitcoin Mining: Three Months Later on: May 14, 2011, 01:41:54 AM
I'm so jealous, if I knew about bitcoins about 1-2 months ago I would have bought $1000 worth of BTC and then I would sell it now... I would be making 7 grand in just 2 months.
10  Bitcoin / Mining / Re: Does anyone know the best GFX card for mining @ $250 or under? on: May 13, 2011, 07:41:50 PM
A unlocked 6950 would be the best. Or a used 5870 if you can find one.

Go for a 5870 new, if not then a used one. Make sure your using a custom fan, not STOCK.

edit: 2x 80mm (or bigger) fans minimum would be good... 3 would be better

me too.

any news on why?
12  Bitcoin / Mining / my 4870 this morning just made some rickety noise... on: May 13, 2011, 05:03:40 PM
Well i decided to turn off my pc for one night after 1 week running it straight on 65% fan speed (around 62 C stable). Then I wake up, and turn on my pc and I hear this like rickety noise... im like WTF! I then find out its my GFX so i pull it out and clean off some dust (yeah my pc got a lot of dust this month...) I put it back, still making that LOUD ASS noise.. im like shit.. now i need to change my GFX... but then i touch the fan slightly (pushing it) and it stopped making that noise.... so im wondering should i go and do this with my new 5870 or is mining not profitable? and how long do your cards last on maximum usage, 60-70% fan, and around 55 C to 62 C.
13  Bitcoin / Mining / Re: Advice on cards for mining. on: May 11, 2011, 03:05:43 AM
I have heard of people using a sempron for their 4 gpu rigs. I think it will be fine using that setup, but if you are planning on doing any gaming or anything else at all I advise a phenomII x4(or wait for bulldozer but then mining won't be as profitable).

Processing power is required to move data around and do instructions, those instructions and data being moved around are done in the GPU... now let us BOTH think what happens when your CPU can't keep up with the GPU in some (i said some) respect? Obviously the GPU is and will always be better, BUT it doesn't mean you put a $10 single core with a $700 GFX and expect perfect results. If your going to do that at least get a duo with 3 ghz or quad with 3 ghz or even a 6 core if you plan to go for the 2x 6990s...
14  Bitcoin / Mining / Re: Advice on cards for mining. on: May 11, 2011, 02:11:13 AM
I suggest getting a better cpu unless you want to get held back and lose performance in mining. Also, I suggest getting 4x pci 2.1 mobo with 5870's or stick with the 5970's or go for the 6990 and stick with the mobo.
15  Economy / Marketplace / Re: Buy and Sell Mt Gox USD on: May 11, 2011, 01:31:12 AM
Purchasing BTC at a reasonable rate.

Contact me (email) at

I buy and sell with trusted members only or somewhat trusted if in a low amount.

Maximum sell/buy is $50 for trusted and for somewhat trusted it is $10 for first transaction.

1. 32bit is windows or linux better? (xp/vista/7/ubuntu/centos/other?)

As far as I know I use a windows 7 ultimate, but I disabled almost 85% of my "visuals" so it uses less memory and is much quicker. I left a few options on like where i can drag things to the right or left and it aligns. Anyways, enough of my talk. I would go with XP. But correct me if I am wrong if unix (centos/ubuntu) is quicker.

2. What is currently the best miner. Electricity is free so we are looking for the fastest miner.

[ATI 5870] 200 to 300 [300 to 400 MH/S ] (~2.1 BTC)


[ATI 6870] 180 to 250 [200 to 300 MH/S] (~2.4 BTC)

[ATI 6990] 700 to 750 (some people having issues with 2 gpu) [700 to 800 MH/S] (~1.9 BTC this data doesnt make sense... but it comes from
SDK 2.1 not supported on 69xx.

Get a pc that costs around $500 to $700 to build but has 3 pci-e x16 slots and put 3x 5870's. It honestly is price optimized and performance optimized. If your a rich mofo, go for the 6870s if you can afford it.

3. What are the best setting for it.

-v -w 128 -f 1 // if you want it to just sit there
-v -w 128 -f 30 // if you are using the pc

4. Is it worth overclocking? How big is the risk of damaging the card? Does it invalidate warranty?

-overclocking invalidates warranty.
-risk is somewhat higher, but thats why you turn up the fan speed...
-i guess its worth it, but check what others say about oc the card you want to get and see what OTHERS have said

Hello I am a new bitcoin miner and I wish to do some transactions with your site.

I am known as psknives in the bitcoin forums. I also have a deepbit account will show my current mining.

Hopefully I can get an invitation.

Thank you for your time!

This is what I have sent them, but I have not received a reply yet.

I sent this on May 5.

18  Bitcoin / Mining / Re: Would this be wise? My college life (no I DO NOT LIVE IN A DORM) on: May 10, 2011, 07:00:53 AM
You can't know who it's profitable for, or it isn't.  Mining was never profitable for me, and in general I don't, but I can envision conditions that I would mine for short terms.  There are many users who mine in their winter months because the cost of electric is either the main method of heat, and therefore running a miner is just a possible bonus to paying the heat bill; or they functionally have near free electric.

If heating is a non-trivial part of your electric expenses then you should be using gas (much power cost per therm than electric heating),  and/or an electric heat pump (greater than 100% "efficiency").   

Because of this, even with heating as a consideration mining will never be free, unless you can make some sucker pay for it for you. Smiley

Generally in GTA, Ontario, Canada you can find apartments around $800 to $1400 (depending on size and rooms) with free utilities (some not all).
19  Bitcoin / Mining / What happens when the difficulty and popularity reach a extreme? on: May 09, 2011, 03:52:10 PM
Already with under 40,000 users we are getting weird spikes on the market and difficulty. When do you think that the difficulty would rise so much that even a 6990 won't be getting barely anything.
20  Bitcoin / Mining / would 3x 5870's be profitable? on: May 09, 2011, 03:06:39 PM
I am assuming thats prob one of the best crossfire options... but i know i got to get some HEAVY cooling done or else its going get blazing hot.
