Hi, some friends and I have been testing upgrades with their G4 Cubes. I think I remember reading in some thread that some processor upgrades aren't compatible with VRM Upgrades, but I can't find it. We're testing with an ARTMIX VRM. The Cube has the MC7447 patcher applied. I have a...

I've tried it on a couple of Macs, this one DA and a QS. The same thing happens on both. It works with a Radeon 9000 AGP graphics card; if I add a Radeon 9200 or 7500 PCI card, it also works, and I can boot from the PCI card. They work with just a PCI card. When this GF4 x8 card is connected...

@joevt I've mentioned this before. Without covering 3 and 11, even any G4 won't boot. If I cover them, I only hear the chime, but it doesn't go beyond that. No option key, no target mode, no finder, or anything, both with the flashed card and with the PC ROM. Neither one lets me go beyond the...

Yes, of course, I've covered 3 and 11 like the other one, otherwise it won't even boot. The same thing happens to me as with the flashed one: it turns on, I hear the chime, and nothing else—no image, no boot menu, no target... I don't have an AGP-PCI adapter.

@joevt I've already received the other GF4, but it doesn't seem like it's going to be easy. I've installed it in the DA along with a Radeon PCI card, and the PC ROM still won't boot the Mac. Something in the hardware must be preventing it; it must require some hardware modification. Then I...

I've tried telnet, but it didn't work. I tried it with an eMac next to me, but I get nothing. I write in the DA but it freezes after entering the command. On the G4 DA, if I use the GF4, I can't even access OpenFirmware. I'm not sure if I understood the instructions correctly; I don't have much...

Wow, I've never connected via telnet with Open Firmware. But I need the patch to boot the computer with the GF4, right? I've tried booting the computer with the GF4, and after the "chime," it seems like it won't boot, it won't display, it won't do anything with the Command key (it doesn't seem...

Hi, when I said NVtool, I meant I used a program for OSX PPC to modify the MHz, but I don't remember which one, many months ago. It's similar to what you can do with ATIccelerator, just change the MHz values and save. I didn't add any straps, I don't even know how to do it. I'm still searching...

Hello. I only have the last two ROMs I tested, which I've attached. I didn't make any modifications, I don't know how to do them, I just used some NVtool to modify the memory MHz, as the name suggests. I've been looking for the original ROM and can't find where I saved it, and I don't have the...

In the macos9lives thread I explained a few posts earlier that it was originally an iMac G4 1GHz with GF4, which I overclocked the bus and SWAPed the CPU to an MC7447. https://rosysumenteinquieta.blogspot.com/2025/07/hace-unos-dias-os-mostre-con-imagenes.html Thanks for analyzing the iMac ROM...

So, those consumption graphs are of no use to us if the Cube's problem is excessive temperature in that area.

This leaves me a bit puzzled, because a few replies ago someone mentioned that maybe the Radeon 9000 was too much for ARTMIX, but according to your graph the Radeon 9000s consume around 15-16W, and as far as I understand the most common replacement for a Cube is a Radeon 7500, which according to...

Under OS9 only the CPU_Director_1.5f5 version worked for me, the others gave me an error when opening the application.

Thanks for your help. I finally found a version of CPU Director that showed this information in the MDD under OS9, and it wasn't the latest version. I verified that the cache ratio was 6:1, and the cache chips support up to 300MHz, so I decided to change the ratio to 5:1 by modifying the...

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...
