Since Zokim has previously posted that he has a 2,1 Mac Pro, the 2.5/5.0 issue is a totally moot point and the 4870 1 Gig would likely be a good choice for him/her
 
Are they 2 dual dvi's? like two 23" ACDs.

And, could you post some cinebench benchmarks for your 1GB card. I have a 4870 from apple and want to see if it's worth the upgrade to 1 GB.
Nope, they are single-link monitors. I've heard that one of the DVI ports offers dual-link, but the other is only single-link.

From what I understand is that the 23" ACDs are single link, so does that mean that a single link cannot work when plugged into a dual link?

My Mac Pro is 2,1 3GHZ 8 core, but it's not a 2.0 PCI, so I would still have the 2.5/5.0 issue right?

No, it will work. If it's dual-link, that means it can support gigantic monitors AND regular ones. If it's single-link, then it only supports regular monitors.

From what I understand, the XFX cards provide 1 dual-link port, and 1 single-link port. So you could run:

2 normal monitors
or
1 gigantic monitor and 1 normal monitor

Lannister is correct. I am driving a Dell 30" via Dual-Link DVI @ 2560 x 1600 and a 46" LCD HDTV via DVI @ 1920 x 1080 with the flashed XFX card.
 
Well after a couple of days with my XFX 1GB I'm having a couple of issues.

One is that itunes & quicktime now quit when i wake my monitors from sleep. This happens 100% of the time. I see that v0N also mentioned having the same issue earlier in the thread.

There are also a lot of people on apple discussions with the official 4870 having the same issue - so it may not be down to the flashed card.

The second problem, and this has only happened once is that this evening one of my displays was basically fuzzy. Kind of like the fuzz you get when a TV channel goes off air...

Has anyone else come across this?
 
I've experienced your first problem with my flashed Sapphire 4870. It's an issue with the 4870s and macs in general, as you say.

Just to clear things up, most of the XFX card variants work as well as any cards do? So an XFX ZHDC works as well as an XFX ZHFC? Just thinking of selling my Sapphire 4870 1 GB to get an XFX 4870 1GB as I'd like dual monitor support.
 
Can we get a benchmark comparison of the Apple 4870 512 vs the flashed 4870 1GB?

I posted this way back somewhere. Mudbox got 80 FPS with the flashed 1GB and 105 FPS with the retail 512MB. Windows games are unaffected.
 
How I killed two Connect 3D

I killed two Connect3D HD 4870 1 Go.
I built a custom rom, using pipomolo's method.
I flashed the card.
Everything worked, could boot Windows, Mac OS X, hd the gray screen at startup, the card was recognised in System Profiler...
Then I put the computer to sleep for the night, and then, I had nothing else than a black screen, couldn't even boot in Windows anymore, and worse, I couldn't even boot with another card (NVIDIA) while the 4870 was plugged.

Second try, with a new card. Flash it the same way, boot several times on Windows, Mac OS X, everything works. Shutdown the computer. And that's the end: now I have a black screen too.

Why does everything work and then the card goes wrong when the computer goes to sleep or shuts down? I cannot even reflash the card, although I could reflash mistakes when I tried with an Asus.

This card had the same exact specifications as the Apple card when using atiflash -i

Believe other folks have had the same issue which boils down to the the brand/make/model of monitor that you have as per past posts if I recall correctly, not sure if there was ever a fix found for this or not though.

Thanks for the response dude, it hasn't happened since that one time so maybe it was a one time glitch, I hope!
 
The "snow" or "noise" screens happen with even the OEM 4870s.

For me, they always instantly fix themselves.

Others have had to disconnect and reconnect monitor.
 
Fuzz, snow, noise thing seems to be related to issues with card and monitor going into sleep mode (apparently plague of original Apple 4870 as well - at least the accelerated software crashes). Disable screen blanking in power settings and start switching off monitor and you won't see the noise again.

Thanks v0n I'll give that a try
 
I apologise for being a complete numpty, but I was just wondering if someone could tell me how to find and the remove the Netkas injectors that I installed to use a 4870X2? There were 2 .pkg files that I installed - the ATI_Init and the one to enable QE on exotic cards. The .pkg's don't give the option of an uninstall...

I have searched on these forums, and google, but can't find out definitively. I saw a mention of 'use terminal', but my knowledge of terminal is limited to command line rendering in mental ray.

If someone could point me in the direction of some simple instructions, or post them up here, I'd really appreciate it.

I have just ordered a XFX 4870 and would like to get rid of the injectors before I flash it.

Thanks in advance!
 
Very bad fuzzy snow XFX 4870 (ZHFC)

Hi guys, I am having some problems with my xfx 4870 (ZHFC). After flashing the card boots up fine in both osx and windows 7, however there is a significant amount of "snow or fuzzy-ness" as explained by the above poster.

This happens everytime I boot and in BOTH osx and windows... I am using a 30" ACD with Mac Pro 2006. I can't figure out why... is this the result of a bad flash? Eventhough everything boots up ok?

Also note, I've tried an apple 4870 in my machine and it worked fine. No problems at all.

I flashed with the popular walkthrough:

http://web.me.com/jacobcroft/4870Flash/4870Flash.html

Could this be because it's a ZHFC? Any help would be greatly appreciated :(
 
Well, I got rid of the 2 extensions installed by running the 'ATI_Init' pkg (ATY_Init and natit), but I can't find whatever the QE for exotic cards pkg installs. If someone could tell me what file I'm looking for and where it's located I'd really appreciate it.

My new 4870 arrives today, so I'd like to get this deleted before I install it.

Thanks.

u dont need to remove exotic cards pkg. it will work fine with 4870, and it will be vanished once u update to 10.5.8
 
Update on "Snow"

I though perhaps the snow and fuzziness was, maybe a result of the flashed rom "slight overclock" on the ZHFC with what seems like a "lower quality" constructed card. I figured maybe because of the lower quality, it maybe can't handle the slight overclock of the rom.

Anyway, tried other posters 50 C and 55 C , cooler roms however the snow problem has persisted.

I then flashed back the original pc1xfx.rom back to the card, and low and behold...the same snow problem when booting into windows.

I'm forced to assume that this is a defective card??? Can anyone chime in to let me know their thoughts..I really don't want to buy back the Apple 4870 :(

I guess it could be a bad card, but perhaps it is a flakey DVI cable or connection. Is the DVI cable hardwired into your monitor, or can you try another cable? Do you have another monitor you can try? It may be a compatibility problem between your card and monitor, which would be a bummer. Even the Apple 4870s are very specific about which monitors they like (i.e. the jumping cursor problem).

I have never seen any snow on my ZHFC, but I have a different monitor (Westinghouse L2410NM) with a DVI-HDMI cable. I do have the jumping cursor problem only if I connect my Acer P221w. As a result, I now have my P221w running on the original HD2600XT in the second video card slot along side the XFX ZHFC to prevent the jumping cursor. This has a minor annoyance of the secondary display ending up in a random position on each boot, requiring me to go into System Prefs to fix the position.
