Hd5830 Sapphire/HIS crossfire

Hi guys,

Before you'll beat on me for not buying the gtx460, I have to say that I received my Sapphire HD5830 for 160€ vs. 210€ for the 460gtx at that time. Now it's 150€ vs 180€/190€.

However, I expected a little more from a 5800 series. I have decent fps in modern games but I want to go Crossfire with this card. I am searching for a second card and found one online for 112€ (119 inc. freight) but it's a HIS. I am new to these crossfire things as the last rig I built was in 2003 and by then thing were different, you only had one card xD.

Besides the pros and cons of crossfire,

Is it possible to set up a Sapphire hd5830 with a HIS hd5830, both having a gig of RAM and 800Mhz core clocks?

Does someone actually own a HIS hd5830? Are they relatively quiet? (reviews say yes, but I don't trust these enclosing fan designs)

Is my CPU fast enough to manage the supplemental card?


My system:

Phenom x4 955 @stock clocks
Mach Xtreme Tech Black Diamond 4GB DDR3-1333 (7-7-7-24) @stock clocks
AsRock 890FX Deluxe3
Silverstone 750W ST75F-P (87+ silver with 1 powerful 12V-rail)
WD 640GB Caviar Black SATA3 HDD (-->OS+games)
WD 250GB Caviar SATA2 HDD
PGSB BX-500 gaming case @ 4x140mm/120mm vents
and eventually 1x HD5830 1GB from Sapphire Tech.

yes you can crossfire two cards from different AIB's. So your fine to crossfire a Sapphire HD5830 with a HIS HD5830.

I leave nothing at stock :)  Overclock that Phenom!

If several reviews say the HIS card is quiet then it most likely is.

Yes its possible to crossfire, manufacturer wont matter as long as its the same series of card, never had any HIS cards to im not sure on noise levels. And you're cpu would be fine for it so yeh. it should all be compatible.. just the noise level i have no idea on :D

thanks guys! really glad to hear that!

@omgitzfatal:

I'll do overclock it, but I gotta buy a new heatsink+fan for this action. I was planning to do it, but the spending for the graphics is priority. Acutally I know a guy who has boosted his x4 955BE to x4 4,2 GHz or x6 3,6 GHz xD (do not without excessive cooling!)

Yeah with some decent cooling and a bit of luck ( getting a good chip) and knowledge you can reach some pretty insane speeds, Got my Core i7 920 @ 4Ghz 24/7, it has been to 4.6Ghz before :) 

Good luck with your Overclocking and I hope you enjoy your 2 HD5830's! (BTW you got them for a very good price!)

yes there are some places online where, from time to time, you can make a bad ass deal... like p*xm*nia.com. small but legit sortiment.

do you actually think 750w (12v 60A rail), is enough for a hd5830 crossfire overclocked setup? how much additional consumption can I expect with 10-15% OC for VGA and CPU?

Each card at stock will eat roughly 14amps each (maximum) and your CPU will consume roughly 11 amps (maximum) Then I expect the rest of your system to use another 10amps so your at a maximum total of 49 amps which leaves you with 11 amps or 132W (11A x 12V), thats a fair bit of OC headroom.

I expect you could overclock the cards by atleast 10% without touching the Voltage, and I'd ecpect you could overclock the CPU by a few hundred Mhz without touching the voltage.

kk, I'm glad I took the 750w strider plus because I initially ordered a 600w cougar,. But then I thought what if I want to upgrade to CF one day and changed the order... nevertheless, I know think that would be better off with a 850w+ because of transistor aging when overclocking and so and headroom with CF to make some insane OC'ing...

I saw a similar rig to mine for 2000$ (!!!) some SB really rip people off. only differences are that 2k rig has twice the RAM and an x6 with same clocks and probably a not so expensive 750w PSU...

Yeah those pre-built PC's make me laugh, Always overpriced and full of overkill in the wrong area's. For example 8GB of RAM sounds great but in reality the average person wouldn't even use 4GB.... It also has 1TB of hard drive space, I use my PC for gaming and CAD/Web design work and I've only used 270GB.... Just overkill, Then they have some generic PSU, The PSU IMO is the most important component so I just wouldn't trust a generic PSU ever.

It saves to do some research and build your own, forget pre-builds....
