Nope...currently all cards are made by the same manufacturer. Same pcb...same BIOS...different decal

QUOTE(ramli sarip @ Jul 9 2008, 12:57 PM) can cooler master extreme 500watt support cf 4850? QUOTE(ben3003 @ Jul 9 2008, 01:43 PM) i dont think so, it is not true power, 4850 need 450w true power. Actually you can run the 4850 on the Coolermaster eXtreme 500. I was using that with my 4850 before upgrading to the my current PC Power & Cooling 750watt CF Edition. |

Wonder if we could find this here? I like the low profile design. Not that the Accelero ain't nice or anything but it's too monsterous for my taste

As I've stated before, the 4850 will run on the Coolermaster eXtreme 500 watt. I've used it before so I should know. Not sure about the 4870 though.

My guess is can if you run on minimal peripherals. But once u start adding stuffs (fans, drives, etc) then it will become unstable and your system will shutdown or reboot.

Sure we've seen the list. So the coolermaster 500watt is not listed but that doesn't mean it can't run the 4850 smoothly rite?

Exactly the same as all cards are manufactured by one company appointed by ATI. Even the bundled accessories are the same. What u need to look for is warranty period and after sales service (RMA history, etc.). And oh...which company offers the nicest cooler decal
QUOTE(pr0t0typ3 @ Jul 10 2008, 01:04 PM) how about the pcb, circuits board, capacitor, mosfet, memory chip, etc.. are they all the same for reference card? |

eXtreme is not true power but an entry level PSU. What u need to look at when deciding on a PSU apart from the Watt rating is the 12v rails. Single rail or multiple rail, what's their rating. A single powerful 12v rail is prefered. And for some, modular PSU is a NO-NO. It adds more resistances to the current flow.
QUOTE(zeustronic @ Jul 10 2008, 09:18 AM) earlier u stated "extreme" 500W rite? AFAIK its max output 500W, but if Real Power 500W which is 500W continuous . correct me if i'm wrong. |

Ok got another 4870 for CF today. I've enabled the "fan fix" in the profile I created earlier. Fan speed is set to 40%. Right now it applies to only one of the cards. How do I enable for both? The second card is idling at 80 deg celcius, kinda hot compared to the first card

So I've decided to CF my 4870 while waiting for the 4870 X2. My initial worry was my PSU (Silencer 750watt CF) wouldn't be able to take on both cards as it's only certified for 2900XT crossfire. Popped in the second 4870 and threw everything I got (Crysis, COD4, Grid, etc.) all night long. So far the PSU is taking it very well. No lockups, crashes, 3D performance hit. Oh by the way I have 2 HDD, 2 optical drives, 2 CCFL, 6 LED fans, SoundBlaster X-Fi XtremeGamer, running on AMD64 6000+ X2 + MSI K9A2 Plat and Team Xtreem DDRII 800. My only concern now is the temp of the second card

 Will try it right away QUOTE(kaiser_falco @ Jul 17 2008, 09:35 PM) oh yea for cf user that want to adjust both card fan profile make sure look for this: <Feature name="FanSpeedAlgorithm_0"> <Property name="FanSpeedAlgorithm" value="Manual" /> </Feature> [<Feature name="FanSpeedRPMTarget_0"> <Property name="Want" value="0" /> </Feature> [<Property name="Want" value="40" /> </Feature> <Feature name="FanSpeedAlgorithm_1"> <Property name="FanSpeedAlgorithm" value="Manual" /> </Feature> <Feature name="FanSpeedRPMTarget_1"> <Property name="Want" value="0" /> </Feature> <Feature name="FanSpeedPercentTarget_1"> <Property name="Want" value="40" /> fan speed algorithm 0 for first card and fan speed algorithim 1 for the second card.. |

Right now all HD4xxx cards are using same PCB, CAPS, BIOS be it Palit, Asus, MSI or the rest. Later only will u see diff cards (OCed, different BIOS, PCB, cooler, etc.). So if u get the Palit as shown in the pic, shouldn't be any problem as it's the same as the rest.

I've said it many times before and I will say it again, to date all cards are manufactured by one company appointed by ATI. Not sure bout HD4850 but the HD4870 uses the Qmonda GDDR5.
QUOTE(Matrix @ Jul 18 2008, 04:38 PM) i think the RAM used is difference, this is where cheap RAM and quality RAM comes into play. Added on July 18, 2008, 4:40 pm 2 x 4850 in CF mode can destroy the 280 already...and you still have money left for 1 more 4850. Nothing to tok liao...overpriced and under performed. |
