I have a 5850, Throttled by Bitminter Client?

What are your core temperatures looking like?

You must be overclocking it pretty good to hit 400mhash on a 5850, overclocking balls to the wall is not likely to get you the most money these days with difficulty being so high. You're better off undervolting at a slightly reduced clockspeed.

It is a water cooled system, and the card is a 5850 Black Edition OC'ed EDIT:Underclocked to 930Mhz Core Clock and 1200Mhz Memory Clock.

The card is recycled from a gaming system, I have an FPGA on order which I will mine Litecoins with once ASIC's come out. I don't care about killing the card.

You know bitcoin FPGAs cannot mine litecoins right?

Litecoin mining requires a significant amount of memory that the boards do not have.

BTCASIC.com FPGA's have sufficient memory.

Are those the generic dev boards that are also sold on ebay? If they are, that onboard memory is much too slow. You'd have better luck mining on a GPU

The red light indicates that you've reached the temperature threshold for that particular card.  You may want to message Dr.Haribo regarding your issue.  Good luck.

I think I remember doc telling me that the red light means that you've overclocked your GPU.  If your GPU is running at a cool temperature, then I wouldn't worry about it so much.  You should be perfectly fine.

Have you tried turning the memory clock down?

[DrHaribo]

BitMinter client tries to run the GPU as fast as possible at all times. The red light flashes when the needle reaches the red section. It simply means you are above what is considered normal speed for your GPU. Probably because you are overclocking. If you overclock a bit more it will probably stay in the red all the time.

Even with cheap electricity, I'd look into underclocking your memclock, because you might end up getting a faster hashing rate.  Personally, when I underclock I find that my gpus mine at a faster rate than when it's stock.

[chewie]

Try underclocking your mem clock anywhere from -100 to -150 from the GPU clock.  You'll find various posts on mining efficiency that will tell you the exact figures to try on your mining rig.  Good luck.
