First 1ghz GPU on HD3870!

Thanks to K404 and Largon i succeed to clock my HD3870 to 1008mhz, here some results(1.5v vgpu and watercooled):

Some crossfire results befor the mod, have te find how to clock both cards over overdrive limits:

1335 on the mem? can i say LOL :D

LOL ? U may mean 1335 is low clock for a 1Ghz GPU ;) Stock cooled HD3870 can do that :)

I'm loving it. Keep on crankin it. :eek2:

good job fellas

The 06 score for single card is weak for some reasons... with a Q6600 at 4GHz and a 8800GT clocked at 730/1835/950 I did 15334 on the first run...

Impressive crossfire though ;)

For those that missed it...

wow

could u make crysis gpu test @

1280 pixel
4x aa
no af
everything high
in win xp


best available free online Pokemon Game on the internet PokemonCraft

also free complete including all gba games Pokedex

Nice :)
To increase Xfire OC limit you should flash both cards with a bios that has higher stock clocks: http://www.iax-tech.com/video/3800biosmod/03.htm

Thanks men and for S1mon a HD3870 isn't a 8800GT
here what i can do with a GT:

Thanks m8!

congrats , 23.5K is amasing!!! :clap:


i like this cards

here with HD3850 256mb CF = 17.8K DEFAULT :D >> http://www.xtremesystems.org/forums/...d.php?t=167528


next week arrive Two Powercolor HD3870 PCS edition :D

congrats once again

regards

Congrats on the GHz mark pinto, glad I could help- the real work wasnt done by me though ;)

Keep pushing!!

3870's are impressive in crossfire..


nice work....:toast:

Some tests with crossfire unable and HD3870 flashed to 830/1200 default

how about this DEFAULT Xfire on 3850 :yepp: :D

http://img518.imageshack.us/img518/2...dm06217ns4.jpg

have you tried ati tool to overclock the cards in crossfire over the limit set in overdrive?

Does the limit raise if u flash the bios to higher frequency?

atitool didn't work for the second card.
yes overdrive limits are increase with the bios at 830/1200 defaults frequencies (1500mhz for the gpu)

thanks alot, keep up the good work !

how was the volt mod done?????? bios or physical?

If you can do 24k 3d06, can you do crysis in ultra setting mode 1680x1050 ? and average 30+fps ??

could we get a real game performance like crysis gpu benchmark

since this 3d marks are useless atm
as much as u increased ur cpu u get more score

WoW :eek: nice clock!and look good be able to see 1GHz+ on 3870, hope i can do it too :p: Nice Results :up:

btw. what temperature on full load ? Thanks.

wow thats amazing, water w/ 1Ghz :clap:

in case you need bios download... i made it :D

http://www.iax-tech.com/video/3800biosmod/03.htm

if anyone needs higher freq... let me know hehehe

Its really a ? now, but I'm thinking the 3870s Extreme OC could be the Crossfire 06 choice over the 2900?

Amazing achievement!! nice dude..u just broke 1000 mhz barrier with just water

If they don't have a cold bug and can hit +1200mhz under LN2, dunno if it will run outta volts before hitting 1.2ghz, temp probably won't be a problem.

It sounded like R600 was too hot for LN2 while still having some juice in reserve.
RV670 doesn't have the heat problem, it seems, but only has ~150w to play with. (AMD mobos can supply extra power, from what I have heard, but also won't have +5ghz quadcores)

Simply awesome bro.

Of course it's true! In single gpu 1ghz is really easy with 1.52v, i'm think every body can do it, i'm just the first to try the mod ;)

Cefurkan in Crysis crossfire isn't effective and my goal is to increase my hwbot rank and to to climb in hall of fame ranking, don't care about Crysis (finished three time already), come on man you're in the 3D team section!

Nice to see that 1Ghz is possible with not too much voltage :)

Good work pinto!

Crazy card clocks, nice job pinto :toast:

Can't wait to clock my 3870's cooled by dual MCW60's and BI-GTX360.

Go for two Maze5's. Much better deal, and better performance/flow too.

this should be possible on a 3850 also

Nice results :up:
These cards are looking better everyday, keep up the good work. :)

Physical vmod right? Still no virtual way of vmodding?

Please include your vGPU voltage because it is very important information.

1.53v according to other thread http://www.xtremesystems.org/forums/...5&postcount=65

Good Clock.

yeah I was thinking the same thing, I was expecting higher scores for high gpu and cpu clocks

But still, 1ghz gpu is what we've all been waiting for someone that actually managed to get a hold of one to do, great job:up:

Sorry, didn't post my voltages earlier! The 3DMark06 was taken at 1.53v. I am tempted to shove more volts, but am curious if any of you water users have tried 1.6v+ yet. My 3DMark06 score is quite low in compared to everyone else due to my E4300! :p

I am now doing 24/7 stability testing on some lower voltages. I've been running ATITool while I was sleeping and it has passed for 5 hrs w/o artifacts on 958/1280 at 1.45v, load temperatures are 48C.

Could you modify the bios below(which has a higher fan-speed profile) to 860/1200 for me? Thanks in advance!

http://www.uploading.com/files/IFYV1NN0/112007.rar.html

wow....1.5v watercooling...seems HD3870 is running cool :D

1Ghz air :slobber: :bananal:

Really impressive.

Keep pushing it.

wow, awseome achivement 1.0ghz gpu clock :eek:
keep pushing :D

Great results! :clap:
Brings back the days when Sampsa got a x1800? to 1 Ghz

Is it actually safe to sustain that vGPU setting for 24/7?

In case you missed the other three or so posters who asked about Crysis...

Can you run Crysis at medium with AA @ 1680 x 1050 and stay over 30 FPS?

:confused:

wow 1GHZ theres some rockin clocks! :up:

Is there a link on how to do this exactly I'm confused and think it would be a entertaining read.

how do you know that the mem doesn't have the timings tweeked to hell and beyond?

what's you rather take, DDR2- 1200 7-7-7 or DDR2-1000 3-3-3?

i run my card on 1,5v and still on stock cooling can do

http://img99.imageshack.us/img99/8572/14664kn1.jpg

tried 1,6v but cant even run 1050 i think its to hot :) time to give some water

Is there no way to clock up the 2nd card for 24/7 use? :(

Could also be related to what Shamino said: It wouldn't even break 1100MHz core until the Over Current Protection is removed.

could you post some crysis results? I'd like to know how it fairs against the 8800gt at such high clockrates

What kind of temps are you looking at under load with 1.5v

1.5vcore is pretty nuts for aircooling on a GPU, this RV670 is one hell of a chip guys. Congrats on those massive clocks :up:

thats pretty impresive indeed.
I hope someone crossfire 3870's @ 1100+ core

Thanks but If you'll raise the fan speed to 25% -30% faster it would be perfect.

Great results to all!! :toast: What do you guys use for voltage changes? Thanx.

hehe maybe the card can go further if over current remove (under air of course)

@AliG
ill try to test it tonight

@HousERaT

i include the temp log from riva tunner on the pic,should be ard 60'c i dont know why i get those 75'c spike?

@SSXeon
please look at this post for the vmod
http://www.xtremesystems.org/forums/...d.php?t=166623

anyway can break 15k at last :)

there you go :)

http://img513.imageshack.us/img513/2662/2095uz4.jpg

average 20fps :ROTF:

now i understand why nobody wants to test crysis:D :shakes:

4xAA ;)

Run it without AA :D

The scores are madness..
I like. :D
