What's with multiport reporting 1.45 profitability over last 24?

Sold an $80 BTC-E USD code no problems.

Would like to sell you a BTC-E code. Will PM details.

I'll give this a shot.

because yolo

Was mining here no problem but even with a difficulty drop it reduced my expected payouts/hr. Also did you start restricting hash rates because pool grew > 50%?

$300 Paypal for all 3.

If you will take Paypal I'll buy 2 7850s.

I would like to sell a $62 BTC-E code to you.

Edit: Ended up being a $65 BTC-E code. Payment was very quick after I sent the code. Would definitely sell to her again.

Mined like 80 FRC but haven't received payment yet. Sent an email so we'll see how that turns out.

Thanks for linking to the BIOS, just to confirm you flashed that bios on the 4L?

Are there other companies that may have spare GPU clock cycles they would be willing to sell/rent? Thinking a service like OnLive

I resolved this issue.

The previous issue seemed to be caused by the voltage being limited and the clock would have issues constantly attempting to downclock to 850/1250 (for me at least) to compensate for the low voltage.

If you turn up the "Power control settings" in CCC you can lock in a higher OC.

Using +5% Power control Settings, 1055 GPU/1575 MEM and a higher fan speed I was able to get the card to do 600+ KH/s via cgminer

This was for the SAPPHIRE 100352-4L Radeon HD 7950

I really enjoy the reference cooler design for being able to push all the heat out of the case but the noise is really unbearable above 45%.

Based on this thread

I think someone is considering the possibility of bios flashing the 7950 to a 7970. This could unlock additional shaders. Good to see if it works.

That intensity correlates about with that KH/s. I get a steady stream at 19 intensity of ~330 kh/s with jumps up to 350 on occasion but that is the total max of the card.

I have been discussing with multiple people an issue with the Sapphire 7950 4L listed
http://www.newegg.com/Product/Product.aspx?Item=N82E16814202030

It is seemingly impossible to get more then 520-530 kh/s with this specific 7950. This value does not change based on over or underclocking, using Reaper or CGIminer be it standalone or with GUIminer-Scrypt. The card has also been noted to reach it's OC speed and then fluctuate rapidly to some stock speed of 850/1200 in line with activity fluctuating from 99% to 60%.

Has anyone else noted this with their card? I have tried many thread concurrencies, worksizes, aggressions, voltages, OC's, OCing programs, mining programs, different pools, stratum. None of these have resulted in the card pushing past this amount.

I am considering flashing the BIOS as a last option unless someone has a different experience.
