Ok. Thank you all.

Default core clock is 810. I can get that up to 950 through OCing, without even messing with the voltages. Could probably get it higher though. I've read about people getting it to 1050. Temperature is at 74'C under load, with fan speed at 78%. All the latest graphics card drivers are installed along with OpenCL and SDK 2.4. With MSI Afterburner I have it set so that OC settings are applied at system start-up as well, so that is not an issue.

Well, tried out Phoenix Miner and I have the same issue. Also, it seems to do about the same as GuiMiner when it comes to Mhash/s. Fiddled around with the settings for quite a while and eventually got it to the best I could, which ended up to be very close to what GuiMiner was doing. Thanks for the tips. I just feel that I could do better with this card. I've seen people doing 400, but I'm only able to do 350 MHash/s.

Ok, I'm having an odd issue. I'm currently running a Radeon 6950 and using GuiMiner. I'm not the best at OCing, but I copied what someone else did with their card. Using Afterburner, I'm able to get my core clock to 950 without messing with voltages. Odd things is, when I run GuiMiner I get less MHash/s, around 295. When it is not OCed and at the default core clock of 810, I get around 325 MHash/s. After messing around with it some more, I found that setting the core clock at exactly 893 produced the best results at 350 MHash/s. I don't think that this is normal. Would someone please advise. Thank you.

Note: OS is Windows 7 SP1.

Followed the link to this thread from the BCM website. I just wanted to say that I for one, really appreciate that BCM allowed the use of PayPal. After reading all of these horror stories in this thread I feel very lucky. I'm one of the people who got in during the open registration, and I have sold several BitCoins, through BCM and PayPal, over the last couple weeks and have had no problems at all. So far anyways. I do however feel that PayPal is not the way to continue with BCM. Although it has been working fine for me with BTC thus far, I have had issues with it in the past while selling 'non-tangible' items. However, I understand that for many people it is very convenient, and even in some cases, the only means of doing BTC transactions. Many of the suggestions posted in this thread will help solving the issue with PayPal, but I think that the right answer is to simply stop using them at BCM. I'm in the same boat with everyone that is wanting to use Dwolla. It looks like an excellent alternative to PayPal, and I would like to see it used at BCM as well.
