61  Bitcoin / Mining support / looking for recommendation for liquid cooling on: June 29, 2011, 09:01:20 PM
I know this is hashed all over, but I have 2 HD 5770, and rather than scouring the web (since this is the equivalent of me trying to find the best set of fishing gear (hint, i'm not a fisherman)), can someone recommend a good water block for the HD 5770?  Once mining becomes unprofitable for me, it'll just be my gaming rig for a couple more years, and I'd like to OC the cards for that as well. 
 
Once someone points me in the direction of a good GPU water block for my cards, I'll match up the rest of the gear (CPU block, tubes,etc) with crap from the same company  Smiley

62  Economy / Marketplace / question about prepaid cards on: June 29, 2011, 03:49:55 PM
Are there any prepaid cards that you don't need to give name/SSN/etc for?  Like if I walk into Walmart and buy one of their cards, how does that work?  I'd like to get one to use to buy crap online and then refill (through places like bitcoinexchange.cc) with GreenDot, etc.
 
Ideally this could be used at an ATM machine as well
63  Other / Off-topic / Red-neck Elliptical machine laptop holder thingy on: June 22, 2011, 04:04:23 AM
So... you or someone in your family has an elliptical (or other exercise) machine?   Want to lose weight but you're bored out of your mind while you walk on it?  Have a laptop and think "Gosh, if I could just read my laptop, trade all those bitcoins, and/or play games, I might actually use the stupid thing!"
 
Well I thought the same thing (well playing games, the bitcoin stuff I didn't find out until later...
 
So here you go!
 
I call it my "Red-neck Elliptical machine laptop holder thingy"  (I'm from Nebraska, so of course I'm red-neck) Wink
 
1.  Here's a view of what I had to work with.  No base to work with, just the stupid arm/hand rests, and at an incline to boot. Sad  I would have much preferred a flat surface, which would have made this a lot easier...  Smiley


2.  So while I was at Home Depot one day for an unrelated project I saw some PVC pipe that seemed just about the right size!  And then the light-bulb went off.   So I ran home and did a quick sketch of the arms and rough-draft sketch of what might work for a frame, and did some measuring for approx total length of the PVC, and then noted the bends and knew I would need some of them.  My sketch also helped me figure out where my load-bearing points would be as well, since the last thing I would want is the laptop to take a nose-dive when I'm in the middle of a 45 minute workout.   I also bought some of that PVC sealant as well so that when all was done I could make the "permanent" pieces stay put. 

This is the frame minus the front piece:


3.  Here's where the load-bearing points are (the one in the middle has the PVC rear pipe on the opposite side of the elliptical main pole, and the next biggest points are up on the "shoulders" of the arms.  The "elbows" hold the next amount of weight (I didn't want too much here since the PVC is the load point, but it is supportive), and the least amount is against my PVC front poles (the plank in later photos help distribute the weight across the system)


4.  Note once your bends are in place, take a Sharpie and draw a line from one piece to the other, so when you remove them to apply the sealant, you get them correct again when you put the bends back on.
 
5.  Here's with the front bar in place.  This is not glued in, so I can remove it.  I also got a plank of particle board (I think 1/4 inch) so that it wouldn't be too flexible, but not too heavy.  The bottom is a 1x2 nailed to the board, and then 1x.25 to give a little lip so that it wouldn't slip off the bottom, and to provide a place for the mouse to rest when not in use (due to the incline).  Note you would have to measure your laptop and figure out what works best for you.


6.  The final look:  my elliptical has a little fan that is normally supposed to cool you off, but instead I have it blowing on the laptop, and then have a regular floor (box) fan off to the side pointing up at me.

 
 
If this inspires anyone in any way, shoot me a bitcoin (my address is in my signature)  Wink   I would be willing to offer advice on your setup as well if you have any questions!
64  Bitcoin / Mining support / guiminer started eating my CPU on: June 18, 2011, 04:10:19 PM
Hey all, just installed another 5770 (already have one), and I started back up guiminer and had a couple of my miners take the new card, and all a sudden my CPU spiked to 100%.  I can't seem to bring it back down short of using the -s flag, but then my GPUs take a hit. Sad
 
so right now I have a happy medium of -s0.005 until I can find a solution.  Thanks!
65  Economy / Economics / Price seems stable now... on: June 15, 2011, 07:30:18 PM
Price seems stable around $19.
 
Now someone lower it down to about 10 so I can buy a couple more pls. Smiley
66  Bitcoin / Mining / guiminer flags on: June 10, 2011, 04:48:08 PM
Sorry for the n00b question, but can someone post a list of the flags one can use with guiminer, and a description of them?
 
for instance, I have -v -w128 right now on mine since I saw it mentioned in the Hardware comparison chart...  but I'd like to know what they are, and additional flags as well Smiley 
67  Bitcoin / Bitcoin Discussion / bit coin address changing? on: June 09, 2011, 04:00:57 PM
I'm confused, when I first installed the bitcoin client, it generated my address (the one I have listed in my signature), but I noticed recently that's different... yet when I "cash out" my coins in the pool, they're still sent to that "old" address and seem to make their way into my wallet.... can someone tell me what's going on here?
 
Should I be updating my pools and shit with the "new" address, or is my "old" address forever tied to that wallet?
68  Economy / Economics / My Personal Plan on: June 08, 2011, 05:21:41 PM
I know some of you save/horde bitcoins, which is your choice.  My plan, however is to sell a small amount of bitcoins per month, no matter what the cost, just so I have something to show for it in the event the market ever crashes. 
 
If bitcoins ever trade at $100 per, I'll sell at least one (a few if possible) every week.
 
If they ever hit $1000+ per, I'll sell as soon as I get them.  Smiley
 
I'm only earning about 1 btc every 2-3 days, so I only have a few right now.  Embarrassed

I will always hold at least one for the very very tiny chance they ever sell at a million or more per Wink
69  Bitcoin / Mining / RDP stealing my GPU for guiminer? on: June 06, 2011, 02:41:43 PM
Hey all, I decided to check in the guiminer today (it stalled for an unrelated issue), and I RPDed in from work.  I re-started up guiminer and.... it only sees the CPU and no GPU??   This happened yesterday as well when I RDPed in for a completely unrelated issue (I was at my house and connected, and then rebooted and checked it locally, so it was normal at that point).

I then restarted up my computer, and restarted guiminer, and the CPU is still the only thing showing up.
 
Can someone offer advice? I don't want to go 8 more hours at just 1Mhash Sad  I want my 179Mhash Smiley
 
does RDP steal a bunch of video resources or something?  Does remoting in not let the computer think there's an awesome GPU there?
 
Is there a way to "force" the RDP session to recognize the video card?
