sorry for the thread revival.

BUT i was wondering the same thing. all i can find are 330k ohm. and i do not want to run a few 100k in parallel if i dont have to. so are the 330k ers going to do me well?:p: :cool:

It works fine with 330kohm i have done it with that

do you mean as a mhz wall?



also on a side note. i have done the ocp mod on my 3850 works great. but now i cant even get a 1026mhz run. cause my mosfets are getting ragging hot even with copper sinks super glued to them AND a 120mm fan. i cant even touch the sink for more then a second when im benching. there are contact points for some more caps that the 3870s have and the 3850s don't. so i might just have to add the caps on the contacts tonight and see.. but any info on helping those mosfets i would LOVE YOU! :D :up: :yepp:

Just ridicules these cards can only do 1200mhz with so many mods. I've seen 2900xt's dry ice cooled @ 1200mhz core. I expected more from these cards, especially because there 55nm instead of 80nm.

double strapping the mosfets might get some more (basically take identical mosfets and attach them in parallel).

lol 16k!!

1200MHz@DICE:D
Look at mine 3870@aircooling;)
1147MHz@1,76V

Volcano12 + "window_open_mod" + -1C outside temp:D

So, no ocp needed, when going over 1100MHz?:rolleyes:

Look at the Core and mem speed 1250+mhz core and 1460+mhz mem

Here is some pics of the mods.

Hectic stuff!

That is extreme :up:

2V and 1263MHz on water?!?!? WTF?

Now that is.. extreme :up:

I can get it to 1288mhz but 3d stable and 1504mhz on mem but not 3d stable
