Strix RX 580 T8G and O8G Crossfire?

Recommended Posts

Posted · Original PosterOP

Hi guys, ive got a question for you guys.

 

My PC is currently running a Strix RX 580 O8G (Overclocked Edition) and i want to buy a 2nd Strix RX 580 for a crossfire setup, unfortunately all the one's ive found for sale in my area are the T8G (Top Overclocked Edition) versions.  Ive read up that the Top version runs approx 51Mhz faster than the plain old OC version, would i still be able to run them in Crossfire?

 

If i cant run them in Crossfire straight out of the box would i be able to slightly lower the Top version's Mhz down to match the speed of the OC version?

 

Also i'd just like to add, ive a Firestrike test on my RX 580 O8G and my score seems abit strange, previously i was running a MSI R9 380 Gaming 4G Crossfire setup and the Firestrike score was 11740 where as my RX 580 scored 11229 (untouched straight out of the box)

 

PC Specs are as follows:

AsRock Z170 Pro4

i5 6600

Patriot PSD44G213381 2133 DDR4 2x4GB(8GB Total)

Patriot Burst 128GB SSD

Cooler Master GX Bronze 750w PSU

Fractal Design Define R5 case with x5 mix/match fans (x2 120mm factory Fractal Design Fans from D-R5, x3 120mm factory Cooler Master fans from Mastercase Pro 5)

 

Additional Info:

This PC in question is just a spare i put together that i occasionally use, its mainly for guests to use when they come over so we can play games together, i thaught i'd upgrade it abit just for testing purposes.

 

Thanks in advance to everybody who replies.

You can run them in CF out of the box without worry; the higher clocked RX 580 will downclock itself.

 

I have a concern with the quality of that PSU, however...

Thanks for the quick reply, i didnt have much problem with running the R9 380's in crossfire, but if the RX 580 will put more stress on the system i dont mind getting a more powerful PSU for it. I just want to see how far i can push this PC with its 2nd handy components, it hasnt cost me too much to build, it owes me about $500 AUD at the moment, im even planning on getting a better CPU maybe even a different Mobo for it down the line. Its all just testing and mucking around for me just to keep my mind busy since im not working at the moment and cant work for quite a while due to a workplace injury (5 disks slipped in my lumbar spine causing pressure on my nerves and numbness down both legs)

I personally would sell the rx580. And just buy a single better card. Used 1080 ti. Or maybe 2070 2080

Thanks for the reply. I would have gone a 1080Ti but the problem is, i already have a 1080Ti in my main PC, this one is just a spare ive built up with cheap 2nd hand component's ive found for sale here and there and i wanted to stick with the AMD side of thing mainly for personal testing and comparisons between both AMD and Nvidia

I see.

No Vega 56 avaliable? You can flash it with a Vega 64 bios and get the same preformance of a 64

Its more down to the quality of the PSU

You can even Crossfire RX 570 with RX 580 regardless of brand or frequency, CF only cares if the GPU is the same model (Polaris 20)

with overclock and tuning yes it can match a stock 64, but dont take it for granted


Studying abroad, ditched the crappy laptop for a do-all laptop double. Dried factory CPU paste, long memory timings, cooler cools the inductors but not the mosfets and an inch of unused internal space on both left and right

Model: HP Omen 17 17-an110ca CPU: i7-8750H (0.125V core & cache, 50mV system agent undervolt) GPU: GTX 1060 6GB Mobile (+100/+500, 1650MHz~1750MHz 0.78V~0.85V) RAM: +4GB DDR4-2666 19-19-19-43 2T Storage: 128GB Toshiba NVMe SSD (KBG30ZMV128G) + 1TB Seagate 7200RPM 2.5" HDD (ST1000LM049-2GH172) Monitor: 1080p 120Hz IPS G-sync

 

The best thing to do is reading the clock speed that doesnt end in a pair of zeros. Software voltage readings are wrong if your motherboard's not a high end model
