Look! I got 450/1230 on my eVGA GT!

3Dmark03: 14142
3Dmark05: 5796

Right know I set in BIOS @450/1230 1.3V. Cant pass the 1st test on 3Dmark03 when I set 1.4V or 1.5V. I can get higher lock 458/1270 when using Riva Tuner but the score not much different, I get better result when I uninstall it!

I am using Maze4 GPU and stock memory cooling, I dont have any better HS than that .

My full system:
IC7-G Moded Vdd.
P4 3.0E @ 3.8, 1.6V
ADATA 4200 @ 2.7V
Maze3, DD Z chip, moded Maze4 GPU. Hydor L30.
Fortron 430W.

I am happy with my GT ,

But I have a question why I cant run with that speed with 1.4V and up?

Hows the PSU holding up? That would be my first guess. Is the memory sinked with some good HS. Maybe the extra voltage is creating to much heat for memory? Just ideas as I don't really know much about your configuration.

sweet overclock, how are the temps with that block? better than the DD 6800 block?

Sorry, I am using the Fortron 530W and stock black heat pipe memory heat sink. I going to get better cooling for memories, feel hot to touch to the heat sink.

I dont know how is the DD 6800, but according to Riva Tuner the temp never pass 56C, and room temp around 24C.

Which memory cooler should I use?

I'd go with the OCZ copper BGA heatsinks. I know they are available at Newegg and I'm sure a lot of other places.

Thanks for the info.

Thats awsome! Water cooling works wonders on the new 6800's. I get 455/1.16 stable on mine. I can go higher on the memory, but the scores dont change much.
