Ultimate Thread: 4890 in Mac Pro

Cindori said:
there are no drivers to check clock or temp in osx


if you change clock in catalyst it is lost when reboot (and re enabled when catalyst is started)

to set clock permanently, edit rom with RBE and flash

well here's the strange part, Before I started, I benched marked the Dummy Drive and it came out the same result as with the Main HDD, both of course IN OSX. Once I upped the clock speed under the Dummy Drive with CCC, I rebooted back to OSX with the same Dummy Drive, and did the benchmark again, it came out much better confirming that the change did make a difference in OSX.

But it wasn't until I installed my main HDD is when the benchmark didn't change.
 
Also when searching a bit I found the following colloection of Sapphire 4890 ROMs. Our card is clocked at 850 so there appears to be 3 ROMs uploaded to this site:

http://www.techpowerup.com/vgabios/...re&model=HD+4890&interface=PCI-E&memSize=1024

One is labeled as Qimonda 40X and the others don't specify RAM. I am quite busy today but if I get a chance I will download and check them out with a Hexedit program and see if there is anything that indicates that it is hynix memory.

If anyone has any thoughts on this please chime in.
 
Time for a Mac Clock Speed app or addition to existing app

Hey, remember the little OpenCl Benchmark? Did anyone notice that it listed a clock speed for GPU? Oddly, I recall that for 4870 it showed the Core speed, while for Nvidia cards, it showed shader clock.

In any case, someone with a brain and some app writing skills (Cindori?) could have a look at how OpenCl benchmark gets that number...and maybe find all 3 relevant numbers. (Core, SHaders and RAM speeds)

Would be a wondrous thing to be able to read these in real time. (prolly just a matter of finding registers and reading them...converting number to a human readable one)

The other idea would be to have the flasher app be able to "read" the speeds from the ROMs. The speeds are always in the same structure in ROMs. Easy enough to mod speeds in RBE or Nibitor and then do a compare to see where speeds are.

Or maybe someone else would like to do a little "GPU Clocks" app that does both of these things...similar to Thomas Perrier's old work.
 
ok this is what I came up with

http://groths.se/atiflashingtool/gputest.zip


for my 4890 it says 4870 and also max 750 clock :S

dunno maybe cause 4890 does not exist in opencl framework.

rommy try run this on a 4870 that is clocked and see if it actually detects clock or just prints stock clock of the apple card.
 
Yeah, tried with the XFX 4870 which runs at 775...showed up same ...

Also tried an 8800GT...it shows "Max 1500Mhz"

Either Apple or Mitch (writer of OpenCl Benchmark) got lazy...instead of actually reading the speed, it is just using a lookup table.

Not even a table really, if it is a GPU from ATI and has OpenCl support...it MUST be a 4870, since it is the only one running in Macs now.

Guess I'll try some different clocked G92s....see if that number is bogus as well.

ANd I was getting excited thinking that we might soon have a clock reporting app....ho hum......

UPDATE: GOOD NEWS !!!!!!

So while the ATI coverage may be faked....the Nvidia support is real.

An 8800GT came up at 1500Mhz and an 8800GTS came up at 1728 Mhz....which happen to be the Shader clocks for those cards. There is no way they would have an entry for 8800GTS since they don't really exist for Mac...so number must be real.

While the Shader clock can be numerically linked to Core, it isn't always.

In any case, there is hope.

Maybe Mitch De reads these posts and will update us on where & how the Nvidia number comes from.
 
Resurrection

Yes, I'm back. Sorry for disappearing right when everything was getting fun, but a few things came up and I had to hit the road and take care of a few things. The last time I was here I installed injectors for my 4890 and all has been well (even with power from the logic board and the optical bay). And I'm ready to do some flashing.

I was initially holding off so that I can backup my rom for semaca, but for the life of me I didn't know how (and still don't). Has anyone been able to help him out since?

Being away, I've forgotten all the in/outs of this whole process. I'm going to list the things I need to do, and someone please tell me if I'm on track here...

First download the Flash tool. Flash the card but remove ... something before rebooting. Then install 10.6.2, and then update something with a new 10.6.2 something er other. :D
 
Well, I feel dumb now. I took it upon myself to download the ATI flash tool and run it. So there I was: Downloaded the tool, downloaded the ROMs Flashed the card... I then Installed qe_ci as instructed here (https://forums.macrumors.com/threads/713428/) then I thought... there was something about removing the stuff I put in to get the card working... oh ya the injectors. So I clicked the "Remove Natit" button and restarted.

Chime, chime, chime.... oh the pain.

Hi Drexus,

What's your card again please ?

Hi Cindori,

Thanks for this clarification, this confirm what i've tested but with a small difference :D ... that in OS X clock speed comes back to normal :D

The Saphire 4890 - same as what semaca had:

Hi Altimeter88,

Yeap Techpowerup's BiosVGA base is great but up to now nobody uploaded one for Hynix, IMHO you'll waste your time to test them, but if you want to try go ahead.

If you don't mind by "Private Message" could you please give me information about your card.

Thanks
 
Anyone have any suggestions on a good place (probably eBay) to get the X1900 power cable? I've been waiting for over a week for mine from ATI, with still no sign that it's even shipped. Does it normally take this long?

Thanks.

Any instructions on what to do with this on a PC? What software am I to use, what is the process?

- Oh and is this the new ROM, or the stock ROM? Do you suppose what happened to me and semaca was because of the ROM we used or the Tool? If it was the ROM, then maybe I should have read into post #1069 first. If it's the Tool, then maybe I should have talked to semaca first.

Are you looking for a second one to power your new card? I just ran one cable to the optical bay. It's a bit of a pain, but if you have nothing else a molex extension is a really easy way to solve it.

I used 2 molex splitters to get power from the optical bay, and yes it's kind of a pain because you have to move your #1 hard drive to another slot, and it helps to temporarily unscrew the SATA plug for the #1 hard drive, but it does work. Unfortunately I'm thinking getting all this power from the optical bay may be causing some problems, so he may be better off buying the proper cables (which, by the way, you can find on eBay too. Search "Mac ATI cable").

And for YOUR problem, did you read this? https://forums.macrumors.com/posts/8813922/ That's how I got mine working. It was doing the chime, chime, chime thing for a while and apparently the 10.6.2 combo update and the qe_ci 10.6.2 installer and the kext's in that archive.zip somehow fixed it so it would get past the chiming and actually boot (with a black screen). Worth a try I'd say.
 
Drexus,

Did you have a chance to backup your original ROM? A few of us are desperately waiting for someone to upload an original ROM form a Sapphire new edition with Hynix memory. If you did that can you upload it here, it would be much appreciated.
