Hello all, I'm currently running two 5870 1GB cards in Crossfire and I'm curious if moving to a 5970 (at 5870 clocks, preferrably) would have an impact on heat or noise. Is the 5970 overly loud when overclocked to 5870 levels? Again, comparing to two 5870s. Any opinions are appreciated.
In decibels, it's certainly more quiet, in real life - depends on your perception. If you don't manually edit fan speeds than you probably won't notice the difference. What's for the heat, one gpu will certainly produce less heat than a two)
So whats with the question here are you considering going with 2 5870 or 1 5970? Or is the question bout adding a 5970 or a 5870?
Hey, I'm experience with my friend's 5970. The single fan has to work harder to keep both GPU cores cool with the 5870 clocks so I should be louder. I would suggest sticking with the setup you have now. Watercool the rig if you want slience and overclock. ps. Im from Toronto too
Im running a 5970 with a 5870 and can sure hear the 5970 fan when it ramps up but it does have the 5870 right above it so does run hotter than if it was on its own. My 5970 hits 93c load about 10 c hotter than it would be on its own. The pci express slots are very close on my Gigabyte mobo http://sites.google.com/site/ayupfromdik/files/5970.jpg?attredirects=0&d=1
Hey i have bout same set up as u but why do u have the 5970 in top slot? They do run hotter up there. You should put it in your bottom slot and and the 5870 at top it will run much cooler there, my cards all run about same temp.
Yes, I already have a 5870 Crossfire setup, but I've been considering replacing them with a 5970 if I could get similar performance and perhaps less heat and/or noise. Sure, I could watercool them, but that's a significant investment that I'm not prepared to make at the moment (to cool 2 5870s and my i7 920).
I would have to say dont think there would be any advantage in it unless u sold only 1 5870 and bought a 5970.
I have lian li case everything is inverted look at the pic i linked. If i swap them around i would need to connect my monitor to the 5870 so i prefer to have them as i do.
Not true you can swap them and still connect to the 5970 just go into bios and set adv. Bois features/init display 1st and select PEG1 (read your manual book of course) there's a tread around here about it somewhere. on my son's Gigabyte board I can see his bios start up like normal but on mine screen is blank till windows loads then my display comes on. could be cause he is using 5850 in crossfire and I using different cards or because I use a 47" LCD TV for my monitor. However if I need to get into bios I just switch the cable back and it shows bois!
Thank you very much ive just done what you suggested and it works perfectly and dropped the temps to 75c load on the 5970. You sir are a star.
must be the 5970, Im thinking sooner or later I'll pick up another one and see if it is cured. Runs great though i have no other complaint.
You certainly could get 2x5870's similar performance from a single 5970; it handles the 5870's DDR5 1200Mhz with stock voltages and the cores 850Mhz with 5870's stock voltages. The 5970 is a dual 5870 GPU clocked @ 5850's frequencies because AMD needed to keep the card under 300W TDP but, it can and will perform very closely to yours 2x5870, although I think switching 2x5870 by a 5970 is a "bad deal" as far as performances are concerned. However, you would save some money at the end of the month because a 5970 "drinks" less "juice" than 2x 5870. Also, a single fan usually makes less noise than two fans, if you know what I mean... Bottom line, if you want pure performance, keep the 2x5870; if you want less power consumption and less noise, go for the 5970 that you'll not regret. Ah... and water-cooling a 5970 is far less expensive lol P
Eh, depends how you do it. If you only buy full cover blocks for your GPUs then yeah, it can get pricy, but if you buy just GPU coolers and sink the rest of the cards...It's not so expensive.
The 2x 5870 fans VS 1x 5970 fan was what I was thinking about. Two cards get pretty got because of reduced airflow, but they don't have to cool two chips like the 5970 does, so what I am wondering just how loud the 5970 is compared to two (or even one) 5870 at load. Of course, the real reason I've been considering it is all the 5970's for sale right now, since fermi has been released and some people are jumping ship.
Krogtheclown Set init display first to boot from the pci and it you will see the bios and it boots into windows fine.
