3870 @ 1200MHz Core w just Dry Ice

huah add 0,25 and gain 200Mhz :D

how about 2v :rehab:

I think you should just try the OCP mod and see hwo it goes first, maybe the mnods are not necessary

How high can you set vgpu till overvolt protect kicks in?

theres no over volt, just OCP

I simply added I didn't replace any

06 GT2 is just killer for the card, I can pass GT1 @ 1200mhz core with just -20+C but GT2 needs -30+c to pass

Knowledge is everything , keep the hard work well done

a question : why dint i see never a vapochill on a gpu ?

I have my Runny/Gosmeyer Cryostar evaps with me, just no compressor or refrigerant :D

These cores are really the rejects, they require lots of volts to run the same mhz as 2900. Good thing these cards are easier to tame than 2900, the main heat is from core clocks, raising voltage by +0.1v creates only the same amount of heat as raising ~20MHz of the core.

Very Very Cool V mod and Score Mr. Shamino :up: :up:

Don't all ATI cards have an OCP chip, which can be removed?

omFg.. thats freakin awesome :eek: :shocked: :shocked: .

Look at the mods, the caps are all over the place :p: :clap:

Shamino, the link in your first post does not work :(

Sick clockin' Sham. :clap:

can you mod a second and put it in crossfire? hehe, awesome mod!

amazing work.... 1200mhz is sweet.... these cards are so much fun to play with...

Good Job shaminó, 1,2GHz is very impressive!:clap:

normal clock.

Very impressive! :D

Love the mods, nice!

Impressive clocks!

Very nice Peter!

I would estmate that your 3870 clocks is pretty equal to a 2900XT running 1160-1180MHz core with 950-980MHz frame buffer, it might even be just as fast. That GDDR4 speed offers alot of bandwidth wich should be enough to compensate for the 256-bit interface. In my testing on air cooling if you max 3870 and 2900 frame buffer freq with gpu set at 800MHz the perf is pretty equal in 06.

Thanks!! Knowing you as the guy who benches the 2900s the most heheh I would believe your estimation! Alright, so that's pretty sweet, at least a whole lot easier to cool than 2900 and doesn't lose much!

woot. saw this from VRZ

well done!

woah very nice stuff Peter... i'd have to say if Hipro and you got together again, manufacturers won't be able to recognise their products with all the extreme mods and component replacements :D

just dry ice? :ROTF:

nice clocks
