Random Murderer, this is the best, I could take week ago:

your spots are the same.

on a side note, if you want to use a different point, grab your dmm and set it to resistance. put one probe on one of those points, and use the other to touch other points and read the resistance. whenever you find a point that has 0Ω resistance, BINGO! you can use that point.
Yes, I already used that method ;)
I find 2 spots also:

Thanks:up:

Can somebody show me where i have to pencil for vmem in HIS HD3850 IceQ TurboX???

Any squeeling sound from inductors at that speed?
Clint, it has been pretty "noisy" card since I bought it. Higher FPS=louder "squeeling":shakes:
nice work:up:Quote:

is there a better mod, and what one is better as well as what values would be good for 1.45V for gpu vcore
also is there a pencil vdimm mod, im kinda lost and the 3870 and 3850 and reference and not in the same thread are making this hard to follow
Aircooling powwa: http://ceemic.pri.ee/45nm/81153.jpg :cool:
Outside temp -1C; Vgpu=1,76V :ROTF:
At the same clock on 3D2003, it crashed several times during Nature:(
Next stop: 1,80V+DICE:D
Very nice ceemic, 1.8v is alot tho.. :eek:
My HD3870 with 5c cold water dident get over 60c with over 1.9v vgpu
Max temp@3D2006 was 30C, @3D2003 it was 28C:D
i need some info from some of you 3870/3850 owners....
the location in green i need cap info and of the blue ones as well. much appreciated. thanks. :p: :up:
http://www.buydurango.com/josh_files/capsss.jpg
820uF 2.5v all 4 of them.
http://www.octeamdenmark.com/forums/...4&d=1203814250
www.mouser.com have them
as always riska to the rescue!!! :up: thanks allot brother.. :D ;) :up: :yepp:
Thanks. It seems to work, although I need to verify it.Quote:

I've not yet tested clocking, as I b0orked the BIOS of my mobo and am awaiting a replacement BIOS chip.
I am going to attempt the Pencil mod for both vgpu and vdimm however,
I have the antec 900 case with all fan slots going at 120CFM.
Will the huge air flow blow off the pencil shading?
It could do, but just shade it as much as you need and then stick a tiny bit of masking tape over it to protect the pencil mark. :up:Quote:

Was cooling with chilled water and temps were below 30C so I doubt that is the issue. Any ideas? Here is the mod:
