Crossfire doesn't necessarily require a cable anymore, it can do its mojo across PCIe. I kind of remember something about a performance hit when you did that, though to be honest I've barely stuck my head into either Crossfire and SLI for the past few years.

I've been stuck in a rut of periodically upgrading my video card to something faster once there's a big enough jump at my price point (usually around $200). I broke out of that rut for my 6950 but then it had a meltdown so I went back into my rut. :D

I'm fairly sure BD's instructions were for Windows, as everything up to Crossfire is exactly how I adjust settings in Windows. Though I wish AMD would do something about that settings app, it's got some nasty memory leaks.

Correct. These cards do NOT have Crossfire provisions physically on the cards. Oh, and one computer at a time I am DOING AWAY WITH WINDOZE FOR GOOD. At the present only two “Windoze” machines are in operation (a Z97 based Fatal1ty mobo system, and my trusty 2008 Mac Pro with the Bootcamp partition).

Finally got a High Sierra Mini ITX based system set up for my oldest son—he doesn’t know yet—and I hope to present it to him for his birthday at the beginning of December since he’s been using a Mac Doorstop (Mac Mini) for three and a half year and let’s be honest they suck. Radeon R9 290x, 3,5GHz Core i5, 8MB RAM, 240GB SSD. Just got it up and working the other day. Obviously throwing it through the usual dnetc gauntlet; a great exercise seeing as it’s a bonafide mini ITX case yet with semi-adequate cooling.

Cranking along with the ovens mostly slow-roasting daily; four Radeon 580s and one Radeon R9 290x pretty much going 24x7. There are some others I power up when the temperatures get below 65°F. Meanwhile I have two Radeon 5870s and one Radeon 5970 (dual GPU) for sale; inquire if interested (the Radeon 5870s work natively in Mac OS 10.6-current without drivers albeit without a boot screen).

Fantastic work Leo! :coffee:

Only thing I can report is that dnrtcL on a Quadro 4000 is 16 times slower than on a Radeon 7950, 225 Mkeys/s to 3,600 Mkeys/s. :(

very impressive output lately Leo!!!

MB - missing your output!

BD - glad to see you pop up in the stats every few days!

Yeah I'll explain why eventually. At the moment one of the systems is in limbo and the other I intentionally nuked and am still trickling software onto it as I remember I need it.

I eyeballed an RX580 at NewEgg this morning though. They've got an MSI 8GB card for under $200. OTOH 480 to 580 isn't a particularly large jump and the Fury/Vega are still in Nvidia territory.

Most days I don't know where my submissions go, wMac 1.4 is still doing 100 blocks per dy after a mon th break after years of no breaks other than power outages.

Been doing OGR2 some days since MB mentioned it was useful...

Once the weather by me decides whether its going to be warm or cold I'll fire up RC5 at home for a little while, although it'll be a fresh installation. It'll take a while to find the optimal opencl engine, I know automatic chooses one that's a little bit off (not by much though).

It was in the 60s yesterday, today it hit 80s, by Friday its expected to be in the 50s. Some days I can't decide whether to wear shorts or a winter coat. :lol:

Well it looks like I have dnetc saved on my main system although I had to purge my in/out buffer files. However since nvidia doesn't let me specify the fan speed and runs the fan WAY too slowly I need to reinstall afterburner to set my own ramp. At least that'd take care of one of the two systems. Although going from Win7 to Win10 may affect the keyrate.

Can you tell me more about afterburner, is it Windows only?

Yeah, MSI Afterburner, Windows-only. I think you actually linked me to it originally.

I probably should install it on my system at home too but that system is so damn flaky on 10, I hate to rock the apple cart.

MSI bought Rivatuner, which was an old nvidia overclock/fan tool from way way back but now it supports both AMD and Nvidia GPUs. I had some really bad experiences with rivatuner but so far afterburner seems fairly okay. I'm not overclocking, just setting a custom fan ramp so it'll hit 100% a hell of a lot earlier than stock. Stock it wants to throttle the GPU due to heat before it ramps the fan up to 100% which is just wacky. Or at least I think it does, based on whatever MSI is telling me.

I used Afterburner to test the Hackintosh system I built for one of my sons back in late 2016, and I came to the conclusion it’s a usefully equivalent utility (for Nvidia cards) of ATI’s version for ATI/AMD cards in regard to throttling GPU and fan speeds appropriately on Windoze systems.
