Thats my story and im sticking to it...
ROFL, did we ever say otherwise
I have two Sapphire ATi AMD HD5870 Vapor-X 1GB OC
Graphics cards aren´t OC
My best regards for All
mm just got back my 4890 cf and man i love it! these babies kill all frame rates it makes me feel goooooood! they both run 970 stock no voltage increas! I up the voltage to 1/325V each slam that baby to 1GHZ core and omfg! it makes crysis look like the kiddie pool! im runin to bed now it 4:30am here but tomorrow ill run the crysis bench on dual 1GHZ core and dual 1.8GHZ mem
also (FIH) The Don, i have an amendment to my stats on your frontpage.
the 4870 512's were run in my older rig with a P45 mobo and a Q6600 CPU.
Crossfiring and OCing my HD 5770 Vapor-Xs is like shoving portable heater in a mini-fridge (tried it!).
Can anyone recommend me a case fan of pure cooling awesomeness?
The Scythe sflex's 110CFM's are great case fans. 2000 RPM's I believe.
You can add me .
Got two PowerColour 4870's 1GB ram verisons
Using the Sapphire 790FX Pure Mobo
With an AMD Athlon 6400x2
LOL, its nice to be understood
I see Buddie has 2 5870's so I decided to clock this 5970 up to his stock setting and just fell shy of his Heaven mark score..
I used redline just to bump the mem voltage **(not sure if I even needed to but I did)** and Afterburner for the rest...mem VCCD's topped out @ 56c
Using MSI Afterburner I find OR need some advice from the fine ppl in TPU for a cooling curve.
Can someone give me a fan curve for a 5970 so it keeps the components cool but the fan at a reasonable Db level?
I love the looks of those gpu's bro but I hate thinking about how hot the inside of the case gets :shadedshu
Why it say only 1024MB GDDR5 for your 5900? Or is it counting the dual Gpu's as 2 single units. Jus curious
It counts two single units with 1gb of ram allocated to each individually.
crossfire and SLI do not add ram. 2GB dual GPU card = 1GB per GPU = 1GB usable ram.
I think if you check my post history, i say this at least once a week...
will add the latest of you guys tomorrow, imma head off to bed now.
oh yeah and Mussels!, have you tried both one and 2 CF bridges? regarding you flicker issue, know its prob something you've tried, but had to ask since when i overclock my cards with 2 bridges on, it flickers, and it dont with one bridge
Thanks, and yes I remember you saying something like this many times These graphics guys need to fix this problem. How about if the graphics card has 4GB GDDR5 will 2GB only be used for games
Seems like a massive waste hey
Yo guys, is there any benefit using 2 crossfire bridges then just 1?
no there isnt. some people have said there is on 5K cards, but there is NO difference between one and two bridges in my testing.
I wanna flash my card to unlock the freq cap. That's the way to go about it, right?
Didnt think there would be, but had to ask
Yes but it can get quite unstable if you lack cooling.
Ask the super, he require 2 bridges for 2 of his HD 4870's or Crossfire won't work right.
then i would say one of his bridges doesnt work.
i tested on P35 (16x/4x) and x48 (16x/16x) and had zero difference. ran for months with one, and a few with two on each mobo.
Updated with the last of you guys.
if there is anything i should add in the 1st post feel free to say so.
anything is welcome, sorta
