8800GT voltage mods

[scottc19]

I haven't tried AquaMark3. OVP doesn't seem to matter in my case since my card won't respond to higher than 1.29v. I was hoping to get the shader to around 2000, but 1825 seems to be it's limit. My card is one of the lower clocking cards I've seen on here. The voltage mod got me 90mhz on the core and 50 on the shader (800/1825). Not too bad, but I was hoping for more. Now if I can just figure out this memory issue.

I'll try the pencil mod first with these Hynix chips. If increasing mem voltage doesn't help, than I guess I'll go ahead with the vmem buck mod. I measured the voltage around 1.9v+.

This seems really odd, how do you know that more voltage doesn't help,ie what kind of crashing are you getting. Does your card still read voltage after it crashes?

You don't need 1.2k for 1.45v. 3.8-4.2k would work fine for that. You shouldn't have any issues until ~1.625v idle w/ 3.8-4.2k.

So if you use 1.2k, what kind of headway do you think you will get then like over 2v? I used the 1.2k on mine for around 2 weeks without problems, but finally decided to rma since ram never ran stock. I am going to do this mod again on my set of 8800gt now and I guess if they can be pushed to 1.625, then it seems there isn't any point to go all the way down to 1.2k. Seems like 3.8-4.2 will do that trick. I am looking for 1.55max, so you think 4.2k will do or will I need the 3.8(ie is 1.625 with 3.8 or 4.2?)
