Title: Odd Pair 5770 and 5850 Post by: worldinacoin on October 05, 2011, 12:41:44 PM I have two spare cards 5770 and 5850 which I intend to hook onto a spare computer and do some bitcoin mining. Just worried that there will be any conflict if I run two different cards. Any advice from the experts here on what I should look out for? I am using Windows 7. Also any optimal overclocking or setting?
Title: Re: Odd Pair 5770 and 5850 Post by: deepceleron on October 05, 2011, 01:57:26 PM The biggest problem you are likely to have is over(under)clocking software, since each card will have different core clock speeds, and the software likely won't do it's trick on both. The most important thing you need to do is adjust the memory speed on both those cards to 300MHz.
You will also need an adequate amount of power, in 600W+ power supply range, with 3xPCIe power connectors.

I use MSI afterburner to set the clocks and no problem at all once you unlock it. My 5770 runs significantly hotter than my 5850 so I put it on the lower slot. If you set up is like this make sure your 5770 is lower than the 5850. Good luck!
Title: Re: Odd Pair 5770 and 5850 Post by: TyGrr on October 05, 2011, 02:16:34 PM the overclock settings will be different for each card. i have 15 5850s and each one is different. most of these cards will under clock the memory to about 300mhz. this will save on electrical costs and heat.
Title: Re: Odd Pair 5770 and 5850 Post by: worldinacoin on October 05, 2011, 02:54:58 PM Deeply appreciate all the advice, these will certainly save me from a lot of agony and frustrations and time.

Only problem can be heat if u dont use extenders like myself, my 5850 is gettin about 89 C., cheers Title: Re: Odd Pair 5770 and 5850 Post by: TyGrr on October 05, 2011, 04:04:10 PM How do you get Trixx to see more than one card? thx
Title: Re: Odd Pair 5770 and 5850 Post by: DeathAndTaxes on October 05, 2011, 04:47:35 PM Latest version of Trixx sees all my cards just fine.
I think it was only the earlier versions which only saw one card unless all cards were crossfired. Title: Re: Odd Pair 5770 and 5850 Post by: worldinacoin on October 10, 2011, 04:42:24 AM I am having some problems, when I installed the drivers, they only recognize one card or the other, if I don't install the drivers it worked fine. What should I do?
