There's no "desired" voltage we have to choose.
This card get 5 v and 3.3v from the PCI. It needs both.
On old PCI versions, there's no 3.3, so we get 3.3 locally on the board from the 5v with a regulator.
If a new mainboard already has 3.3, with a AMS1117 there's no problem. I have no idea with a switching regulator like you have. Electronic can do weirds things.

If you really want to cut traces, then you have to cute all the traces on the PCI connector of the card where 3.3 is delivered.
There's about 12, see the pinout on Wiki ( the B side is the components side), the A side is the nude back.

Okay, my English isn't very good. But maybe you shouldn't answer anything without reading the target and motive in the first post. The card according to specifications needs three voltages, 2.5v for the "GPU," 3.3v for the SRAM and 5v for the VBIOS.
The 3.3v for the "GPU" is an unnecessary and quite important overvolting. But, everyone who does it any way they want.
And, I did the mod on the first page, so I know why I did this modification and I have quite clear the traces I needed to cut.
What I don't know is if keeping the traces uncut, on a motherboard that has the 3.3v on the slot, the voltage adjustment for the "GPU" I wanted will work properly.

@elmatero's video card burned out after modification without cutting traces in the PCI slot with 3.3 volts.

Re: Chinese Rage XL PCI mods, improved compatibility and looking for a good overclock.

I find out that my Tekram P5MVP-A4 motherboad proviede 5V on 3,3 V line, that was the real reason of burning the card - 5V on GPU Core.
thread: 3.3V PCI cards got extra hot on Super Socket 7 Mainboard

So it makes sense !
I could not find any reason why this mod could burn a card. Unless a soldering mistake, of course.
And I've been playing with electronic for 35 years, it's even been my job 😀

Did you manage to fix it ?
The fix would be just cutting the trace, but on a multilayer board it's not always possible 🙁
Or destroy the pin, also not easy on a PCI connector.

Is there 5 volt on all 3.3 PCI slots ?
A solution would be cutting all the 3.3v input on the Ati card, of course.
Maybe it's where the confusion comes from here above.

Yes on all PCI stots On this motherbord are 5v on 3,3 V line. Finaly I'm using on it 5V PCI cards (IDE and network adaper) and in AGP port ATI RAGE PRO. On AGP ther is correct voltage of 3,3 V.

hello everyone

I recently bought this graphics card. I tried all the drivers in the area and overclocking.
I’m very pleased; the card adds compatibility with Windows 98 and DOS to my 'retro' PC with a Radeon HD, which doesn’t have drivers for Win98.
I use Powerstrip 3.2 for overclocking;
my non‑extreme (everyday) settings are: 139 for 3D, 100 for DOS.

Driver 2647 worked for me:
-Unreal without visual defects in D3D
-FF7 with D3D HAL
-stock OGL little bit slow, replaced with OGL1107. for GlQuake set gl_ztrick 0 and no visual issues
-Sin works lagging with any OGL, SciTech GLDirect 3 CAD driver fixed it

Some bench results:
3Dmark99 default settings - 2382 marks 800x600
Final Reality 3D performance - 6.21
Unreal Gold around castle fly cycle - 34.4 fps 512x384
GlQuake demo1 - 59.9 fps 512x384
Quake 2 demo1 - 46.6 fps 512x384
Quake 3 demo1 - 49.0 fps 512x384

P.S.
In 2647, the OpenGL driver was renamed; for OpenGL replacement batch file should look like this:

COPY Atoglrp9.dll C:\WINDOWS\SYSTEM\ATIO9XAE.DLL

Also you can rename it in the install .inf back to Atoglrp9.dll as it was before and install the driver with Atoglrp9.dl_ or Atoglrp9.dll.

Quake2 should be faster than Quake3? Could you add also default (no oc) results at default 640x480x16 resolution for Quake 1/2/3 (ztrick 0 for glquake and no other game tweaks)?

I have GLQuake and Quake2. For GLQuake you can use 4.11.1091 or 4.12.1091 and it does not need ztrick 0 that takes away some performance (should be faster).
Multitexture does not work with 1106 and 1107, latest that works is 4.12.1004, i use 4.12.1100 for some reasons. I am not sure 4.12.2647 supports multitexture.
From earliest OGL 1073 is fast, but it has multitexture enabled by default and if your driver does not support multitexture it will hang without atidbg.ini setting.

RageXLAGP Intel Celeron Mendocino 533Mhz (mmx)
GLQuake 0.97 (all default, no oc, no game tweaks)

no ztrick 0
GLQuake timedemo demo1 640x480 34.7 (Default OGL) 1091
GLQuake timedemo demo1 640x480 39.3 (MultiTexture) 1091
GLQuake timedemo demo1 640x480 45.9 (Bilinear off) 1091

GLQuake timedemo demo1 640x480 43.9 (Bilinear off) 1100

I am just saying you should get small boost with ogl 4.12.1091
I mainly use that, has no quake menu issues or i use 4.11.1073

in q2 fps increases on 0.1, non-OC
glquake hangs on startup, non-OC, MT off
glquake works fine with OC (same atidbg.ini) 41.4 fps
really strange) usually OC goes to freezes

same for 1073

1107 glquake with OC (same atidbg.ini) 40.0 fps

also 1073 and 1091 needs restart Windows for launch glquake in 512x384, otherwise i got error

Thank you for the inf. Older driver likes it more or something else. Are you sure you did not leave ztrick 0 on for your 4.12.1091 run, it does not need it, ztrick 0 is needed from 4.12.1095 up to 1107v1/2.
I have tiny glquake exit issue only with newer if starting to turn off bilinear at atidbg and no multitexture for newer. I can run glquake at any resolution from 320 up to 1280 without restart (no errors).

yeah, i'm not added it to cfg file, typing manually every time)
