Sabretooth 990fx rev1.0 & R9 290 PCS+ compatability in crossfire

[batpimp]

I have a sabretooth 990fx rev1.0 mobo.

I also own a Powercolor Radeon R9 290 PCS+ 1040MHZ 4GB
(the GPU does not have crossfire connectors ready)

"The R9 290 lacks Crossfire connectors. AMD correctly assumes that most owners will use their R9 290 on PCI-E 3.0 motherboards that have plenty of bandwidth to ensure communication between two or more R9 290 cards. The decision to drop the connectors also saves a couple of bucks in production costs for AMD and its AIB partners. It also results in a ‘cleaner’ design with fewer points of failure."

Am I correct in assuming I CANNOT run 2 of these in crossfire because the mobo lacks pci 3.0?

Can someone confirm that I am correct? This is the first time I plan to get a 2nd gpu but I think I cannot run these in crossfire unless I get a diff mobo.

The GPU is set to be compatible in crossfire with PCI 3.0 but my mobo doesn't support that.

I believe you still can... its just bandwidth is the issue? Don't quote me though...

I then ask why a second 290? One should pound through most titles at 1080p resolutions...

 

[batpimp]

hey thanks for the quick reply.

I was actually hoping someone would correct me that I CANNOT run these together unless I get a mobo that supports PCI 3.0

why a second? I want to run games at 144mhz/fps. I am almost exclusively a FPS gamer and I just got a 144mhz monitor. I need a 2nd video card to hold stable 120fps+. Right now you are right most games run at 60-90 fps but I want a bit more!

Yo batpimp...

...Just some crossfire reading. Note this first link was talking of two crossfire bridges being the cure for using 144MHz monitor. So AT LEAST one bridge was in use at 120MHz. Now there is another driver but still think a single bridge is still used. Nothing about zero bridges.

[FIXED] BSOD @ 144hz 2x crossfire bridges (no longer ) needed

Now about newer 290 AMD video cards. LONG read.

BTW, it is a myth that Crossfire with 290, 290X and 295 X2 cards would not work on Gen 2.0 slots.

[batpimp]

ah very cool.

I will make the leap here once the card goes down 30-50 bucks in price.

Just grab a used 290, they're cheap already.

Hey "batpimp"...

...This is your thread. You started it so you can sort of change course if you want to. Can you take some more high resolution pics of your case and post/attach them to this thread. I am ordering that LUXE case in black with all red led fans and the extra 1M Led strip. Just looking to 'see' as many ideas as possible before I get completely set in what I will do to the case.

Intent is to run 360 rad in ToP of case with push from inside at first and then add pull fans on top if need be.

I mean if you feel like doing some very good pic taking and even a night view. Hehehe.

Thanks man, and good luck on CFx.

I read it has to be the exact card. Is that incorrect? Any R9 290 will do? I have been looking for used ones etc on Ebay. Not sure where else to look.

I will take more today and post them here. I can also take a video on post it to my youtube and I can link you it. It's niceeeeeeeeeeeeeee

ill set a remind right now

 

[EarthDog]

Any 290 will work...

 

[batpimp]

Oh wow. Okay I will start shopping.

Also just got an email back from power color saying:

"You need mobo PCI 3.0 to run crossfire. you can purchase from the sotre you bought it from; go to www.newegg.com or www.cyberpowerpc.com to see if they sell it.

regards,

Power color customer service..."

the broken English and the fact that other people aside from this thread have told me I can run it on my mobo makes me think they are ignorant or sticking to marketing.

found this too

Grab ya a used 290 and have at it. You'll be fine. Saberkitty R2.0 is still PCIe 2.0, as are just about every 990FX MoBo. There was supposed to be a Gen 3 Saberkitty with 3.0 support but I have no idea what happened to it. Asus still has it on their product site but no idea where to get it.

 

[RGone]

I have no idea what happened to it. Asus still has it on their product site but no idea where to get it.

The chip Asus used caused a number of issues and so they changed the status of mobo to "limited edition" (only one production run) and have sold them lately only in EU it looks like. At least no more sales in Usa after the first month or so.

Iv'e seen 290's x fired on the saberkitty not long back before i traded mine off, it looks like pcie 2.0 and 3.0 perform about the same from what i was looking at, at the time.
no ugly bridge needed and any 290 will x fire with any 290, brand is no issue, heat and noise are!!!!

 

[batpimp]

nice. I think I am going to stick with the Powercolors PCS+ for the cooling and low-ish noise.

hey man!

I intended to take pictures yesterday but I had a bday party that started earlier than I thought. Then today I had time but my buddy just asked me to grab a beer.

here are pictures that I used to make my decision to buy the case a while ago. I hope it helps you in the meantime.

Host internally to this site (or 3rd party) if you would please. You are essentially stealing OCN bandwidth to post them here.

 

[batpimp]

I am not sure what you are asking. "host internally to this site" ?

 

[EarthDog]

Host the pictures here at OCF or 3rd party. You are linking to images that are hosted at OCN and using their bandwidth to show pictures here. Not a huge deal, just forum etiquette.

 

[batpimp]

okay I am not sure what you mean by host the pictures here. Sorry I am not a website savvy guy.

You are saying not to submit links from their website here?
