8800GT voltage mods

That vmod looks a lot easier i might try it i only need to get the 1k VR

Your Vram doesnt seem to overclock over 1000mhz is that right? i can bench at 1040mhz stock volts

Yes, it craps out at 1026mhz, even at 2.025v.

Man, this memory sucks. I loosened the timings to Qimonda spec (the stock bios is closer to Samsung 1ns spec - come on partners, put Samsung in the board). And even at 2.075v Mem it craps out real fast at 1044mhz.

That being said I seem to have hit a new problem. The core will not clock over 864mhz. No matter how high I go in the overclock setting in RivaTuner the ROP clock stays at 864mhz.

Anyone else been this high?

Well, the shader seems to like the extra voltage. 2052mhz shader is 100% stable, while the core seems mostly stable at 864mhz. As I mentioned before I can't go any higher with Rivatuner, it will not change ROP over 864mhz.

Shader will run for a while at 2104mhz, but will artifact after a minute or so.

I'm pretty impressed, at 1.315v its rocking!

Proper soldering iron would be Weller EC3001 or equivalent.

Source in US for parts... pots, etc is Digikey.

Go to Radioshack and get some KYNAR 30ga rework wire. Use it for these things. Makes for much cleaner work, and easier to work with SMD. Also, look into getting a nice magnifying ringlight, makes it alot easier to work on tiny SMD stuff.

nice, but i intend to keep my warranty, therefore no vmod...

unless there is a pencil vmod , which is irreversible

GoldenTiger:

I don't think 1.175 or 1.200v would be a problem, those are some decent heatsinks. My stock SSC was 1.137 on the single slot cooler.

Unless you like the smell of roasted mosfet I would advice you install some sinks on them. They do get pretty hot and when you up the voltage they will get much hotter. The copper sinks on my mosfets get up to around 122F.

So, what kind of clocks are you getting???
