Perfect, thank you very much, I'll try these options. :)

Hi, I've been trying to view the cache speed on my 2x1.42GHz MDD with OS9 and Gauge Pro, but it doesn't show any information about either L2 or L3. I can't find any app that gives me this information. Is there a version of Gauge Pro for OSX? Or what app could show me the L3 cache speed, or at...

Hi, it's strange what's happening with this graphics card. I recently got my hands on another 64MB Radeon 9100. I downloaded the original 8500 227 ROM and the ATI 9100 Devid hack, and opened them in Aticcelerator to set the speed to 250/250MHz. Since the Devid hack showed strange speeds in...

Yes, I saw that the fan only moves air through the center. I'll try to make the VRM upgrade mentioned on macrumours; I think it will be necessary. As for the Radeon 9250, in the photos you'll see that the heatsink is already rotated 90º, as I read in a post. I replaced the thermal pad with a...

Thanks for the reply. I also have a GeForce 2 Mac, although I thought either the Radeon 7500 or the Radeon 9250 were better options. I tested the 9250 on a G4 Gigabit with the specific drivers for OS9, and it works well. The fact that it's low-profile and the SE version made me think it was...

Perhaps it's already known here on the forum, but yesterday I found this protoboard on eBay that appears to be from the Dual 500MHz upgrade for G4 Gigabit. https://www.ebay.com/itm/163629740631?mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5338722076&customid=&toolid=10050 It's a shame it...

I've already 3D printed the front end for the Radeon 7500 and the low-profile Radeon 9250. You've told me that the 9000 doesn't fit without moving the VRM, and that's true, and that the 7500 is a very common option, but no one has rated the low-profile 9250, for which I have drivers for OS9...

Thanks for your answers. I have a 6200, but it's out of the question because it doesn't have drivers for OS9. I also have a Radeon 7500, which I thought was the same size as the 9000. I'll have to check it out. I'll have to look it up, but I seem to remember that the Radeon 9000Pro was often...

Hi, a friend of mine has a nearly stock G4 Cube, and he wanted to do some upgrades. He still has the original VRM. One of the upgrades is replacing the graphics card. It must be able to run OS9, so we have two options: an ATI Rage 9000 Pro 64MB and a PC flashed PC Radeon 9250L 64MB. We assume...

Well, I have some news, although not very good news. First, a curious fact. Without an L2 cache, it's not possible to boot with either the original iMac EEPROM or the Lombard EEPROM; neither of them left the factory without an L2 cache. However, with the Wallstreet EEPROM, it's possible to boot...

Thanks for your answers. And @joevt, you're on a higher level, much higher. I'm sure we can find something with that information. @croissantking, I also suspect it could be a cache chip failure. It all started happening when the cache reached 200MHz, and from then on, it got worse and worse...

Well, I think all the 500MHz issues have nothing to do with the processor or the bus. I think there's a hardware problem. This problem has gotten worse and worse, and now it's gotten to the point where the iMac boots up but no longer has an L2 cache, and nothing has changed since the last tests...

A question, how did you adjust the bus to 83MHz?

Mine's rectangular too, and at 466MHz like yours. I thought the problem was solved with the 7410s, but I don't know anymore. The strange thing is that I got it to run at 500MHz with a 2V Vcore, and now it's not stable. I can't even boot it.

Luck is not on my side. Adjusted to 1.83V:

Update: The stability issue seems to be due to excessive processor speed and likely temperature. The first boot seemed to go well, but as it heated up, it gave problems and wouldn't work. I lowered the bus to 66MHz and adjusted it to 500MHz. Upon boot, the chime sounded, but it wouldn't boot or...

The Lombard EEPROM have some value at position 20, the other nothing.

Hi, I did another quick test. Maybe the speed isn't set as a multiplier but as a fixed value, but in my case it's being complicated by the bus overclock to 83MHz. It doesn't like something. Up until now, it occasionally wouldn't boot on the first try, but on the second or third try, it always...

Looking at all my photos, I get the feeling that the EEPROM content is conditioned by the processor speed. Below 400MHz, everything works fine; we've always maintained the expected ratio, but at 400MHz or higher, the ratio drops. No matter what EEPROM is used, it always drops when reaching...

Hi @herd I've tried changing that value, but upon startup it tells me there's no L2 cache. I've attached the .bin file in case I made the change incorrectly. I've also attached the EEPROM dumps from the Lombard 400MHz with 1MB cache, which I believe has a 2.5:1 ratio as commented in previous...
