Yes, its possibel, and realy easy to OC the Parhelia with a Bios hack. With this way you can make the Bulk P. to a Retail too!
What we need is one thing. The Matrox Driver CD.
First you enter the Driver Cd.
Second, enter in "Run":
Your letter for cd drive:\SysUtils\pbioswin /d c:\pinsfile.txt
On drive c: you should now find the pinsfile.txt . Open it. You will see a text like this.
0 2 0x412E
2 2 0x0200
4 2 0x0605
6 2 0x04D5
8 2 0x0002
10 2 0x030A
The Numbers on the left side mark the line.
Third Step:
If you don't want to make a Parhelia Retail, skip this step. But i recommend this, maybe this step chaning something on the voltag, wich allows higher clocks.
You must replace following Codes in order to make a retail P.:
On line 10 0x830B with 0x030A
On line 140 0x91750002 with 0x9F810002
On line 156 0x23230000 with 0x2A2A0000
On line 380 0x42383231 with 0x52383231
Fourth Step:
Changing the clocks.
Line 36 and 56 are the Clocks.
Bulk Version:
Line 36: 200000 ( GPU )
Line 56: 500000 ( Ram )
Retail:
220000 ( GPU )
550000 ( Ram )
Can you see the clock? As example, i have overlocked my Ram to 600 Mhz:
600000
!WARNING!
I still don't know, if you can enter, as exampel, 223000! I don't try it, beacuse i want not that my GPU runs at 2,3 Ghz
Fift step:
Again go to Run:
Your letter for cd drive:\SysUtils\pbioswin /s c:\pinsfile.txt
After the dos window has closed, reboot you PC.
Now you should have a overlocked Parhelia
Before you try this, make a backup bootdisk!!! This is the way to save your Bios: Enter in "Run" this:
Your letter for cd drive:\SysUtils\pbioswin /o c:\mtxbios.bin
But i don't know how to make a bootdisk, wich flash automaticly the Bios
If something goes wrong, i will take no warranty! Its on your one risk!
This is realy better than the Matrox OC tool.
Thanks to my japanese friend, who tells me how to make this
