MCP67M-A2 Volt Mod via pencil or tiny dot of solder help

[CastorTroy]

I've got a MCP67M-A2 (7150M) and I've been playing around with it a lot got a vga bios mod on it for 0.86v in 2d from 1.1v and 555Mhz from 425Mhz in 3d and it's limited to 1.2v since anything beyond 1.2v doesn't yield any more overclock. It shouldn't be too hard to figure out which chip will increase the 3d voltage above 1.2v right? I pencil modded my 4850 and it's stable at 800Mhz from 700Mhz so I figured it's not hard just gotta know which one to mod.

Any way to have the video card share more than 128MB? I know for a fact it is a limiting factor. Once I got DDR2-800 and Overclocked my Turion 64 X2 TL-68 2.4Ghz to 2.6Ghz and the ram went up to DDR2-867 I got an instant 20fps increase just from the cpu overclock alone since the overclock yielded a lot more memory bandwidth. From 425Mhz to 555Mhz yielded an additional 10-15fps boost so all games are playable now. I can even run Unreal Tournament 2004 at 1280x800 and everything on as high as it will go at 35fps.

If I could get a volt mod to boost it past 1.2v I could get 600-650Mhz out of this little puppy!

I notice the 128MB of shared memory is performing quite well since my system memory bandwidth is so high. The PRIMARY bottleneck for resolution is the limit of 128MB of shared video memory. If I could boost the shared memory to 1GB I could get some decent resolution framerate since the 7150M in itself is not a bad gpu. I monitor gpu memory usage and at anything above 640x480 it's tacked to 100% on Insane 2. At 320x240 it uses only 80-90MB and I get like 40-50fps. So does anyone know which Hex string in the vga bios contains the information for the Shared Memory amount? Since there's an option in the BIOS and it's only 64MB or 128MB. I don't think it's impossible to change this amount. I'm waiting on a response from an Nvidia Engineer to give me more info.

Thanks

this is a variation of the 6100 (2 pixel shader, 1 vertex shader)? or they changed something?

anyway, considering how Vista+ can easily use system memory, addressing more memory shouldn't really make a difference?

also, something I remember had some impact on my old 6100 was the HT clock, I remember a 10% OC on the HT would give me some nice gains on 3dmark03
(IMC is on the CPU, so it has to use hyper trnasport for the IGP), I don't know about the vmod, but my 6150SE could work fine without any mods from 425 to 575MHz

When I had a 780G + A64X2 setup, I found considerable gains in 3D when overclocking HT. There's only 4.0 GB/s bandwidth in each direction with the 1000 MT/s HT.

The GeForce 6/7 IGPs only do 2 pixels per clock though.

A shame that the geforce 8200 was scrapped, I would have liked an AM3, ddr3 mobo with it.
As it stands, the geforce 6100 still is alive, you can buy a brand new mobo and a FX 6300 if that's what you really want. "geforce 7025" is a renaming.

ASRock N68C-GS FX is a funny mobo that can take your Athlon 64 X2 and ddr2, and also can take a Piledriver FX CPU with 8GB ddr3 (not 8320 and up), and everything in between except the power hungry CPUs (because it's too low end for them). BIOS can set up to 256MB shared memory (from manual)

Interesting board, but considering the 760G can also be found for cheap, I'm not sure it's a good idea, the same board with the 760G would make a lot more sense,
760G supports PCIE 2.0, AHCI sata, HT 2000MHz... while the 7025 is limited to the Athlon 64 era, also the 760G IGP is a lot better (it's like an HD2400, slower because of the shared memory and with UVD disabled, but still a lot better than the 6100)

I think my 6100 board also supports 256MB as the max shared memory, but as I said, I don't think it makes any difference from using 128mb, altough I haven't tested much (the only new thing I played with it was TF2, apart from Skyrim )
