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.

So winter finally set in at home and my dnetc heating system is back up in operation.

I only have my main system running at the moment, my old 280-based system is still sidelined until I can care enough on a weekend to sort it out. I usually end up sleeping most of the weekend to un-cranky my mood. Right about the time I'm starting to feel normal is when I have to go back to work and the process starts all over again.

Thankfully the government has closed its investigation so I might be able to use my old AMD setup at work again. Had some wonderful boys from Russia try to get into the works and create a big headache for me. No real damage done aside from testing my patience.

Not sure if anyone heard, but apparently the GPU mining market is crashing. As a result GPU prices may start coming down to earth soon. Or AMD/Nvidia will go bankrupt trying to sell products too expensive for their non-mining markets. Or both.

The RX 590 launched this week, which has pushed the cost of 580 and 480s down. You can get an 8GB 580 for under $200 now. Unfortunately I won't be buying any GPUs for a while, I just splurged on exciting car parts like rebuilt OEM lower control arms (front AND rear!) and a rebuilt OEM starter. Now I have to figure out what shop I trust enough to install them, because it's too damn cold & wet to go crawling under my car.

I remember chopping up the floor board in my '55 Stude so I could replace the tranny without laying on sub zero ground in a howling wind.

Is this just a well binned RX480 chip?

The 580 is basically an optimized and slightly evolved 480. The 590 is a process shrink of the 580 that allows it to run at faster clock speeds. Apparently in the 590 they included empty space in the die so the hottest parts of the chip would have more surface area to dissipate heat which is partly why they were able to clock it so high.

A 580 is about 10-15% faster than a 480 in most things. 590 seems to be about the same jump from a 580.

Image

Apparently Nvidia plans to move its excess 1070 & 1080 GPUs by rebinning them onto new 1060 cards, which already has 4 different versions, by pairing them with slower RAM so as not to cannibalize the 1070 & 1080 sales they have left. The more I read about Nvidia's upcoming plans today the more I understand why their stock plummeted upon news of their growing unsold inventory and their plans for getting rid of it. That being said there certainly are a lot of really oddball cards in China from both AMD & Nvidia (beware of eBay!).

As for how fast they are at dnetc? Dunno. Until the 590 comes down I'll be sticking with my 480 for a while yet.

Thank you for the detail! I wonder how fast it
Will be?

I watched a video on Youtube this afternoon which pretty much concluded that for gaming on average going from the 580 to the 590 would yield 5 - 10 more frames per second… I’m not sure that’s worth the extra cost.

This issue popped up one other time, I think it was a month ago. Some sorta dnet bug. Throws the dual Radeon RX 580s into thinking they can crank out 2x the throughput, but in the process ends up literally having them crunch 2x their rated workload. What ensues is the computer locking up when I attempt to log in and “wake up” the monitor output… a power down and reset cures the problem. Of course macOS reports no errors since it’s just via Terminal.app. The previous time it reported my having done 800,000+ in a day. I don’t know what is causing this. The “Macintosh” in question is running 10.13.6 with an 8GB Radeon RX 580 and a 4GB Radeon RX 580 on a Gigabyte Z370 based motherboard with a core i7 CPU. I’m perplexed as to what would throw it into this vicious and possibly destructive cycle. I’ve got two dnet GPU crunching “Macintoshes” with dual Radeon RX 580s working 24x7, but only the one with the mismatched 4GB/8GB cards has done this so far.
