[Request] Unlock BIOS. MCP73VT-PM, GeForce7050 / 620i (MCP73V)

[sabelstrom]

Hi.
I thought of upgrade my kids computer for Christmas because he is now having a Celeron D 346 on a ASRock 775Dual-915GV with 2GB DDR2-800.
 
So I got a MCP73VT-PM motherboard from a Packard Bell IMEDIA B2630NC free from a friend.
 
I googled around to look for best parts and ordered a LGA 771 to 775 MOD Adapter Sticker for Intel XEON and a Intel Xeon E5450 3 GHz Quad-Core SLBBM processor, info here:
http://www.delidded.com/lga-771-to-775-adapter/
 
And I got Corsair DDR2 800MHz 2X2GB (PC6400) CL5 XMS2 from an old not working computer.
 
I installed my Radeon HD6990, but got no picture, but when I used an older GPU I got picture.
Memory at 667MHz not 800MHz, no options what so ever in the bios. Still using Intel® Celeron® 450, no Xeon delivered yet.
 
There is no update bios for this so I am hoping to get some help here, I only get one shot because it is a single soldered BIOS chips and I do not want to brick my card.
 
What I want in the BIOS:
support for 800MHz memory,
support for my Radeon HD6990,
Xeon support (if there is not now),
Overclock options. (now there is none)
 
I can upload my bios If you need it, I don’t find it online.
 
Chipset: GeForce7050 / 610i (MCP73V) Googel
Chipset: GeForce7050 / 620i CPU-Z

AMI BIOS
Motherboard name on the sticker MCP73VT-PM, if I remove the sticker the name is MCP73T-AM.
Similar motherboards: GF7050VT-M5, GF7050VT-M.
 
I read someone tried the bios for the GF7050VT-M and bricked the card.
 
So please help me, I am an afraid I will brick the card if I try modding the bios on my own.

Post screenshots of first (CPU) & third (Mainboard) tabs of CPU-Z.

To my surprise it says nForce 620i and not 610i as i found when i googeld it.

This is not the new processor, it has not arrived yet.

I also updated the microcode in my bios following this: http://www.delidded.com/how-to-update-cp.../#comments

But have not flashed it yet.

GeForce 7050 chipset doesn't support DDR2-800, only DDR2‑667.
Give me links to original & modded by you BIOS.

Ok. I read that GeForce7050 / 610i do DDR2‑667, OC 800MHz but the GeForce7050 / 620i and GeForce7100 / 630i do DDR-800, i guess its wrong than.

But i cant OC without options.

Modified BIOS:

file backup online

Original BIOS:

file upload

New CPU id: 01067A, platform 11 and 44.

Everything seems normal. Try to flash it.
Unlocking isn't my specialization. Ask somebody else.

[sabelstrom]

ok. i will change the thread name and hope for the best.

But what about the gpu? Is that a bios or chipset limit that makes the hd6990 not working?

About new GPU & old chipsets - it's well known problem without solution.
