-I'm new in this scene so please apologize me if this look like such a noob.
-I'm trying to edit GeForce 4 MX 440 with AGP 8x 64MB DDR 128bit (NV18 core) to change core and memory clocks. I use X-BIOS Editor 1.0 RC3 build 520 (v1.0.3.520). The core successfully changed, but the memory isn't, no matter whatever value entered. I also tried previous version of X-BIOS, but to no avail. I'm trying to use HEX Editor, but don't know the exact location for real memory clock. The usual address C9DC until C9EB doesn't work.
Original clocks : 275MHz core / 256MHz (512MHz DDR) memory.
-Using RivaTuner 2.04, I found out that the actual memory clocks (from low-level/PLL reading) is different from the BIOS. Here's there report of the original BIOS :

-Please help me, any help is highly appreciated. BTW, before this I've successfully unlocked & overclocked Galaxy 6800XT AGP using BIOS mod. Thanks.
