Compare MemVendorID from Freezers and Non-Freezers! Lets narrow down the video cards.

Antares:~ David$ ioreg -l | grep ATY | grep Mem
| | | | "ATY,MemVendorID" = <0600>
| | | | "ATY,MemRevisionID" = <0100>

Mine is a "freezer"...

24" 2.4GHz, running 2GB of RAM (Apple branded, not 3rd party).

I experience freezes in the following configurations:
  • Tiger (no updates)
  • Tiger with 1.1
  • Leopard (no updates) - I did a clean install
  • Leopard with 1.3

By the way, I never did think that this could be a heat-related issue. I am in Kiev, so I decided to test it out by leaving the windows open - i.e. let the room temperature drop to about 4C/40F. It makes no difference.

Lets hope the next software update actually fixes something! :)

Oh well I think we have another iMac freezing thread that like the rest has proven nothing. :(

It's proven that VendorID 0600 has frozen more often than not for those that have it.

It's also proven that VendorID 0100 is less likely to have problems.

This thread is showing precisely what I wanted it to show. A possibility that one vendor has more issues than another.
 
"ATY,MemRevisionID" = <0100>
"ATY,MemVendorID" = <0600>
Mine is a freezer in everything else than Tiger 1.0.

It seems to me like the number is pretty even between 0600's that freeze and those that don't. Someone with a moment should update kkat's list.

Are you sure about that? There are people reporting freezing on all VendorIDs, there are also saying their machines have never frozen on all IDs as well. Nothing has been proven here at all. This is all just random speculation.

Yes. https://forums.macrumors.com/threads/385030/

So far there is over a 60% freeze rate (of some nature) with the 0600 Vendor. If you take into account the 4 people with an 0100 vendor such as myself this isn't looking good thus far for the 0600 vendor.
 
"ATY,MemVendorID" = <0100>
"ATY,MemRevisionID" = <0900>

3 freezes since purchase(10/17).

1. in WOW with med. high settings sitting in an inn. able to move cursor.

2. booting into osx from xp. froze right away. mouse locked and everything.

3. in crysis demo while trying to change graphics settings from med. to low. mouse still worked.

i'm running leopard. imac update 1.1 (scared to apply 1.3 after all i've read.

all in all i count myself as one of the lucky ones as it's never frozen via the typical ways( scrolling through the dock, mosaic and arabesque screen savers, etc.)

Currently on this poll you linked to the results are pretty much exactly the same for both VendorIDs. :rolleyes:

ID 0100

No freeze = 57%
Some Freezing = 29%
Constantly Freezing = 14%

ID 0600

No freeze = 53%
Some Freezing = 29%
Constantly freezing = 18%

Yeah there is a lot standing out there...
 
Crack is bad, m-kay.

Vendor 0100 No Freezes 4 16.67%
Vendor 0100 Some Freezing 2 8.33%
Vendor 0100 Constant Freezing 1 4.17%
Vendor 0600 No Freezes 9 37.50%
Vendor 0600 Some Freezing 5 20.83%
Vendor 0600 Constant Freezing 3 12.50%
 
(He broke it down into two categories to show how similar the distributions are.)

Note that 600 vendor freezing is pretty inconclusive in itself.

A poll where 24 people in total have voted is far too small a sample to glean any useful data from whatsoever. Perhaps if 240 (or better yet 2400) people had voted you might start talking about 60% to 40%.

I'm one of those with the 0600 vendor ID and no freezes at all by the way.
 
The only thing that poll shows is that there may be about twice 0600 cards than 0100. But if you look to relative percentage, the freezing issue occurs exactly with the same rates. I think we're pointing at the wrong spot here.
 
Mine has froze sometimes.

Your right unless the total number of vendors in each group is known it would not be possible to come to any conclusion. As stated in post 26 my 2nd iMac is not a freezer "ATY,MemRevisionID" = <0100> "ATY,MemVendorID" = <0600>
Was not smart enough to check the vendor number on the first one. Lets hope this is solved soon.

Granted the sample is still too small even for the forum, but it's looks like "5% affected" may have been quite an underexaggeration!
 
Hey, I'm not trying to be scientific. Obviously there's nothing conclusive about this poll, but it does help against complaints that trivialize iMac users with freezing computers as just a very vocal minority here on MR.

No trivialization but I do still think that forums like these tend to attract those with the issues searching for answers to them or a place to vent so you'd expect them not to be a minority.

Here's a thread just for non-freezers with plenty of posts.

However, if my machine were freezing I'd be plenty vocal. There's nothing wrong with that. Heck, I'm vocal for the freezers. It's shameful for Apple to have this issue at all even if it's less than 1% of all the machines sold.

Fair enough. :)
 
guys the info i had posted was unfortunately incorrect. The issue has nothing to do with the memory id's, sorry for the inconvenience. I still hope a solution will released soon though
