X8 X4 Crossfire 570

Recommended Posts

Posted · Original PosterOP

I got a question, I am building a new system to keep me going a few more years using newer graphics cards but older parts.
Will I get any stutter issues from a PCIE 3.0 Port running at X8, crossfired with a 4x port?

I want to use the other 4x port for another M2 SSD to get the maximum speed.
The board is a z97a gaming 6, and a Intel 4790k

Crossfire & SLI isn't very well supported in games. Theoretically it should work with 4 lanes, but you'll probably run into all kinds of issues due to poor multi-GPU support.

stuttering is more about its implementation in games rather than your PCIe standard used.


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

CPU: i7-2600K 4493MHz (multiplier: 43x) 1.35V (software) --> 1.4V at the back of the socket Motherboard: Asrock Z77 Extreme4 (BCLK: 104.5MHz) CPU Cooler: Noctua NH-D15 RAM: Adata XPG 2x8GB DDR3 (XMP: 10-11-11-30 2T 2133MHz, custom: 10-11-10-30 1T 2229MHz) GPU: Asus GTX 1070 Dual SSD: Samsung 840 Pro 256GB (main boot drive), Transcend SSD370 128GB PSU: Seasonic X-660 80+ Gold Case: Antec P110 Silent, 5 intakes 1 exhaust Monitor: AOC G2460PF 1080p 144Hz (OC'd 150Hz) TN Keyboard: Logitech G610 Orion (Cherry MX Blue) with SteelSeries Apex M260 keycaps Mouse: BenQ Zowie FK1

Thos are the limits of pcie on a gtx 980, 4x 3.0 with an rx 570 the differences will be very negligeable as a gtx 980 is a much better card.

Is only a slightly better card.

Regardless of the bandwidth issue, crossfire is not recommended. Like with SLI, you'll get crappy performance in any games that aren't optimized for it, which is most games. Instead if buying two 570s, buy a single 980 Ti, a 1070, or a 1660. You'll get steady good performance.

Yes, JoostinOnline has a good point, however most of the new AAA titles have support for dx12 mGPU, and if you have crossfire as well, than with these two technologies you can actually get realy good coverage of a verly large number of big titles, but any indie games or even some big titles will not have support for any of these technologies, and in those games it will have felt like you wasted your money on the extra ( my extra r9 290 only cost 60 canadian and at that price it is worth the perfomance increase). As it turns out most of the titles i play support crossfire or mGPU, Far Cry 5, COD:BO4, SOTTR and ROTTR, HITMAN 1 and 2, BF5...  But you may have a different taste in video games and may not be fortunate enough that the games you like to play support these technologies, that is why some people say crossfire is dead and other people say it is thriving : Ask them what games they play. So I say it depends on what kind of a gamer you are, and it is a hit and miss, so I would probably say it is dead if I was recommending to someone else, as i don't know what games they play. One more powerful card is definetely better than CF, better temps and power consumption, but crossfire can also be a cheaper way to get high fps depending on the games you play, so people who comment on crossfire only think about themselves, and it does definetely vary depending on what kind of gams you play.

 

 

 

 

 

Sorry, I had to do it.

Thanks everyone, your feedback has been really helpful. I think I'll do it, I plan on investing into a intel 660p for the m2 to run through the third pci 3.0 port to help maximize performance in conjunction with the two 570's
