This, also... the 4650 isn't really a capable card, I dont think its even worth the trouble for the amount of mhash it gets.

Then whoever must of been conducting transactions must have been completely incompetent. If someone was to buy btc and pay for it via paypal...

First the buyer would send say I suppose half the agreed amount as personal reasons, then seller would send the buyer the btc and the buyer would pay off the remaining balance after the confirmations go through.
Would paypal know this is originating from a btc transaction? Not at all.

I think the reasons are paypal is suspicious of transactions that deal with $100+ on accounts that arent old, being used alot, arent connected to ebay selling in any manner, etc. For example! My friend sent me $130 to buy him some headphones while I was on vacation in Germany after I flaunted how AKG was by far the best brand. They suspended my account, 2 months and I received it back (Double whammy was, they found out I was underage during phone call...had to wait for my bday) I had sent $100 to my mothers paypal (as she has german bank account) and the rest to my bank account which got frozen... soo... they get suspicious easy.

Ahh the difficulty increase yep. That happens every 10~14 days? Correct me if im wrong

ATI Mobility Catalyst™ 11.4 Driver Suite 1 is needed for OpenCL Support on mobility apparently... and 10.1 should still work, If not then 4600, and 4800 series wouldn't of supported it.

Mobilities actually do support openCL.

So I've been mining and mining right and saved up some btc, is there a site like mtgox that does payouts in paypal? or a list of trusted users on the forum whom buy coins. I usually sell slightly under priced if that was to be the case (i.e gox has it for $20, I will sell for $17) I am paranoid in the fact that I only trust paypal when it comes to online buying & selling transactions.

When it comes to GPU's yeah... you can mix then up, but some companies use custom PCB and clock rates which can effect performance. with ATI, I've always Stuck to Sapphire... and for a good reason, with two 6970 Im getting 56~59c Max load with the fan pushed up to 90% with no additional cooling, the same applies to my old 5770 which has lower temps. It might be to my case arrangements, but who knows.

Ok, so I setup the laptop with ufasoft, its pulling about 20 mhash not anything to be excited about but I figure  its enough to cover btcguilds donation percentage. As I game alot I'm looking into a dedicated miner, which will be placed in an office space and not in my room (As it is a sauna in here) I suppose I do have to look into dummy plugs as the only multi monitor setup is located in the room. Did whats suggested for now atleast and its pulling higher Mhashes so thank you! (I tried it on this desktop, pulled about 80mhash, but meh... it takes away from the GPUs)


The mining rig I was putting together in Newegg totaled to about $650

It has

Sempron 140 2.8ghz (Possibly unlockable to an athlon apparently?)
The cheapest ASROCK Dual PCI-E 2.0 X16 Motherboard (DDR2)
1GB of the cheapest ram
a Corsair 850w PSU (it was 2nd highest in "best ratings" category)
and Two ATI 6870's totalling $349 together (was cheaper then the 6850)

OS would be XP, as i still have some keys for it... I cant imagine

If it yields over 600Mhash though, it should pay for itself within a month or so I'de imagine.

I also experimented abit with a Sapphire 5770 Juniper stock (Not vapor-X)
that doesn't use the phoenix cooler, or those open aired ones... Its in between  I guess.

A little OC/UC 960/1000 with Afterburner and tuneup utilities brought it up to 210mhash

Well, A friend recommended this to me as I leave my pc's on constantly, I have three questions. As I have a spare laptop I want to try and use since I never use it, minus well leave it as a miner no matter how bad.


1) When I had my 6970 cross-fired I had a rate of 430.5 stable, while using the flags -v -w128 -f0. Out've crossfire They each get around 358 each using the same flags. He did calculations and said i should be running 710 or so with the 6970 in a crossfire setup, or separate as well.

2) I have a Gateway NV54 series laptop, when I run guiminer (latest) It says I dont have any openCL devices, so im assuming portables dont work with this?

3) Is CPU mining worth it when say I go to sleep (10 hours of mining) running next to GPU mining, I have a 980X might go 2600k not sure yet.
