8-18-2008:

So today begins the actual journey down the path to maxing out my system. Lets have a recap. I just want to say that I do not have any screen shots of the benches as I was too wrapped up in the moment but I do have some specs and pics of the modded card.

Moving on!

Seeing as I will be hanging on to my beloved EVGA 680i and my trusty 8800GTX's I am going to treat them like the awesome parts they are. So I just ordered this slew of parts:

EK NF4 1.1 Southbridge Block
Danger Den 680i Northbridge Block
2x EK FC-8800GTX with Acetal tops
2x EK FC-8800GTX Acrylic tops
EK 680i/780i MOSFET 1
EK 680i MOSFET 2
Danger Den Fillport

Now this means that the ONLY parts not being water cooled in my system will be the RAM, HDD, and PSU. I have been contemplating moving my DVD drives external and moving my HD's into 5.25 hd coolers so I can install a triple 120mm radiator. I currently have a thermochill and will probably shell out the money for another one.

I am going to order 3 of these to mount the radiator upright in the front.

Here is the radiator that I am looking at:

ThermoChill PA120.3 3x120mm High Performance Radiator

Now moving on I got to reading and talking with my buddy about possibly volt modding my card so I decided to do some research and then go get the parts needed for the project. So I did! I got the Variable resistors and soldered them to the surface mount on the 8800GTX. Here are some pictures of the mod instructions and my installed test version:

Instructions:

My card modded (click the pictures for HQ pics):

After I measured the Vcore and the Vdimm with my multimeter I adjusted it to give 1.45v (idle) and 1.4v (load) to the Vcore of the 8800GTX and 2.3v for the Vdimm. After about 2 hours my stock (13389 with 1 8800GTX and CPU at 4.05ghz) 3DMark 2006 score was crushed when my 8800GTX ran stable at 715mhz on the core, 1.65ghz on the shaders, 2.25ghz on the ram thus giving my system 14532 with ONE card.

I then ordered the parts for the other card and removed the vmod so I could run my other card at the same speed.

There will be more updates! Thanks for reading!
