After FINALLY receiving my 7800go vanilla from Dell, being on backorder for a month, I immediatly put it to work with 3DMark 06 and then proceeded to overclock and then voltmod it.
using the Xtreme-G 84.56 drivers with an auto detected OC of 364 core 923 memory I got a respectable 3123.
I used the 1.2 Volt mod and set to 400/923 and managed a 3380 which is respoectable in its own right, top 20. - I should also mention my 90w power adapter fried out on this setting, re-ran the test with the 130w brick.
playing around with the oc settings I came across artifacts on anything with the memory clock set over 950, the core wouldnt go much further at this level then I really got experimental and ran with 450/900 and presto this is my result.
for some reason the higher my core, the lower my memory clock max seems to go. I used the same 1:2 core to memory ratio on my desktop 6600gt setup, which runs stable, and here it seems to work well too.
gonna play with some more settings and see what my Max score will be before I ask SirBA to chalk me up there on the list
