2x 4870 watercooled: 31.2k 3d06 done with cascade

[MusicIsMyLife]

After a disappointing session last Friday with 2x 4850 we (Hoschi and me from BenchBrothers) had another try last evening. This time we changed nearly the whole setup: motherboard, cpu, psu and graphic cards. We took 2x 4870 from PowerColor. The cards were watercooled (only gpu) and vgpu-modded. Unfortunately they didn´t switch voltage into 3d-mode and so we had to deal with that.

Our setup:

qx9650 @ 1.82 volt ultramarine blau cascade built by piotres (-100 degrees) ASUS Maximus Extreme (unmodded) 2x 1024 mb Cellshock pc14400 es (thanks to saaya :up:) 2x hd 4870 by PowerColor (watercooled gpu, 1.28x volt) OCZ EliteXStream 1000

OCZ sent us a new psu for our benching-rig which had the first use yesterday. Thank you guys for sending this psu – it did a very good job. :up:

During our initial testings with watercooled cpu we got 25.7k 3d06 with just 4.4 ghz. Raising clockspeed by another 1 ghz+ we should get a respectable performance boost, shouldn´t we? And yes, we got it:

3DMark06

Benching without ln2 is kinda boring…. ;)

And our final score:

After our initial testings during this week we wanted to reach 30k. But that barrier we smashed with our first run at safe 5.4 ghz (30.3k). After raising clockspeed to 5.6 ghz (keep in mind: 1.82 volts and only cascade-cooled!!) we got another ~900 points. This should be one of the fastest 2-gpu-scores on the orb.

Cheers (Hoschi on the right side and guess what - me on the left side:D ):

And guess what: This cpu isn´t maxed out yet. Because we could benchmark all other benchmarks at much higher clocks:

3DMark05

compare-url (http://service.futuremark.com/compare?3dm05=4379802)

2k5 at 5.7 ghz isn´t to shabby. :) And what about 2k3 at this clock? :D

3DMark03

compare-url (http://service.futuremark.com/compare?2k3=5890152)

112k with 2 watercooled gpus – not too bad. Peak in gt1 was 6,910 fps. ;)

3DMark01

http://www.benchbrothers.de/bilder/scores/2008/4870/106209_s.jpg (http://www.benchbrothers.de/bilder/scores/2008/4870/106209_l.JPG)

2k1 was a "must have". Lod +3 and no special benching order gave us this score. After another run of car low we got 107,280 points. Unfortunately our rig crashed after this run so that we couldn´t capture a screenshot. But here is the orb-link:

compare-url (http://service.futuremark.com/compare?2k1=9397106)

And what do you say about am3 at 5.85 ghz?

Performance is poor at this clock. Something eats up performance and we don´t know what it is. In our opinion the score should be 5k to 10k higher at this speed. But today we don´t care about – we are happy that we could complete that benchmark at 5.85 ghz with 1.82 volt. :D :D :D

That´s all for now. Maybe we can run singlecard-benchmarks today. And if we have enough time we will put the cards under mach2-units. With this cooling and about 5.650 mhz cpu-clock we should be able to break into the 32k-zone. :)

Thanks for reading. :)

Congrats to very nice scores.., and a sweeeeet chip.., looks really nice and U both deserve the beer.., 2 beers.. :-)

[[XC] gomeler]

Impressive! Those GPUs are just crying out for a little more voltage, 950MHz should be easily do-able on water ;)

[George_o/c]

Congratulations guys, absolutely amazing scores ! :up: Especially 06 and 05 are sick ! :eek:
What a great cpu you have :) Have you tried raising the Vcore more ?
CPU @ cascade, 4870CF @ Mach2, and 7-6-5-15 (although the last one, won't improve the score as much as the first 2 :p:) and you will easily get 32k :up:

Keep up the good work guys ! :)

[Nosfer@tu]

GREAT work :D

And nice with the story

[thebanik]

great cpu u got, amazing clocks for such measly volts, :), and impressive scores too, congrats....

[Szlobi]

Very Nice Work! Grats clocks and result.:)

[systemviper]

Love the benches, that was a great run, good job keepin on it!

[Gautam]

These cards are extremely powerful. O.o Very nice job guys. :clap:

[andre X_X]

those are very nice results guys :up:
cant wait to see how 4870X2 on CFX :D

[K404]

Nicely done guys!! :D

Beers were well-earned ;)

I bet you know how crazy the scores would be if the cards were frozen too ;)

[nachthymnen]

Congratz guys!!
Really nice setup and results!:clap::up:

[Oliver]

Good work looks good...

These cards will really shine with cold and more juice, with a 5.8g+ quad...

Keep pushing it...

[HousERaT]

I like what I'm seeing here. My vote for more voltage to the GPUs also. :up:

[Teedeck]

I feel small

gomeler;3148101']Impressive! Those GPUs are just crying out for a little more voltage, 950MHz should be easily do-able on water ;)

Yes, this setup cries for ln2 on cpu and mach 2 on gpus - and for more voltage. :D

For the moment it´s a matter of time. But maybe we can have a killer-setup in a few days. ;)


Congratulations guys, absolutely amazing scores ! :up: Especially 06 and 05 are sick ! :eek:

Thank you. And yes, 05 and 06 are really nice. :yepp:




What a great cpu you have :) Have you tried raising the Vcore more ?


When we tried higher vcore the last time on our Maximus we couldn´t get better results. 1.82 volt seems to be either the sweetspot of our cascade or of our Maximus. Maybe we need to mod this board.... :shrug:




great cpu u got, amazing clocks for such measly volts, :), and impressive scores too, congrats....

Yes, I love this cpu. Funny thing is that this is our replacement-cpu. :D The first one we tried did also 5.6 ghz under cascade and 1.82 volt through 3d06. This chip had no problems booting at -100 degrees while the one we used for these 4870-benchies did have a problem once. So we made our decision to put this golden chip in a daily rig and keep it as replacement.

In the last few weeks we got problems with our setup and so we tried this replacement-chip. And as you can see it was the right decision to keep it. :yepp:




These cards are extremely powerful. O.o Very nice job guys. :clap:

Thanks Gautam. It´s a pleasure to read these words from you. :yepp:




Love the benches, that was a great run, good job keepin on it!

Thank you. And yes, we will continue....




Very Nice Work! Grats clocks and result.:)


GREAT work :D

And nice with the story

Thank you. :)




those are very nice results guys :up:
cant wait to see how 4870X2 on CFX :D

I think with our cpu 2x 4870X2 would fly. :eek:




Nicely done guys!! :D

Beers were well-earned ;)

I bet you know how crazy the scores would be if the cards were frozen too ;)

Thank you.
Like I said: Maybe we can do this in a few days. :)




Congratz guys!!
Really nice setup and results!:clap::up:

Results aren´t that high like yours (congrats for your cfx-benchies :yepp:) but we work on that. :D




Good work looks good...

These cards will really shine with cold and more juice, with a 5.8g+ quad...

Keep pushing it...

I hope that the cards work well under cold. We will see.




I like what I'm seeing here. My vote for more voltage to the GPUs also. :up:

OK, we will do it next time. :)




I feel small

No need to feel small. I think it´s 90 % luck that we found this cpu.



Yesterday I had a little time and I did some singlecard-benchmarks with nearly the same cpu-clocks. And here they are:

Unfortunately I couldn´t break into the 320k´s but we will work on that.

Nice job dudes :toast:

Yes they are, it's fun to bench again :D

[Brandybuck]

Great cpu:eek: Congratz :up:

[saaya]

congrats! :toast:
nice cpu! nice 2k1! nice Aq3! :toast:
so did you use both cards under mach2 for this?
what gpu temps did you get with the cards under load?

you guys def need to dig out that "Wandfluter" again for the nice light effects, with the light like this it looks quite crappy :P
with the light from an angle elike the last time the walls looked really cool and stylish ^^

[MusicIsMyLife]

Nice job dudes :toast:

Thank you very much. :toast:

Both cards had watercooling on the gpu. Mach 2-units weren´t used.

Yes, you´re right. Last time it looked a bit better. Let´s see what we can do the next time. :D

[saaya]

so this was with water only? nice!!!
so when are you going for the mach2 units? :D
4870s are burning up around 170W at stock already iirc... so those mach2 units will be quite busy removing all the heat, especially when oced!
but im curious how well the rv770 responds to low temps, maybe its mostly heat limited and doesnt need that much extra vgpu... but im affraid it wants volts... lots of volts :D

and then the gt units are too weak and water might get you better results at high vgpu than mach2 units LOL :D

[G H Z]

so this was with water only? nice!!!

Check thread title saaya :D :toast:

[3BABY]

Very nice results guys!!

have you managed to get 900+ GPU Mhz at that Vgpu? also did you try 1200Mhz mem speed? cant wait to see some vmoded 4870's i think their begging for it !! :D

[MusicIsMyLife]

Sorry for the delay guys. I´ve been busy for a few days. :)

Yes, water only.

Our mach2-units had their first use with our 2900xt´s. With 1.40 vgpu we had ~0 degrees under load with these cards.

I don´t know if the 4870s produce more heat or not. But I think that shouldn´t be a major problem.

We tried them under cold a few days before. Unfortunately we hadn´t luck. :down:

We flashed 950/1100 and started 3d06. In gt1 we got a nice increase in fps but during gt2 the system freezed. Since then, both cards never booted up again. :(

No condensation, no damage - something went wrong but we currently don´t know what. :shrug:



Next step is to unsolder vgpu-mod, put them under stock cooler and try to boot up - let´s see what happens. :)

[drizzt5]

Nice scores!! I love these new cards :o

[Stumbo]

Sweet dungeon lol.

[MusicIsMyLife]

Good news: both cards are alive again. :)

We plugged them into BlackOPS and both cards stayed at 2b - invoke vga BIOS. We put them as second vga in a pc, re-flashed vga bios and they were up again.

They crashed during gt2 in 2k6 and had a corrupted bios. We don´t know why but we can use them again. :D

[vanovich]

some nice results there .what software did you use to get lod to work in 01 ? we benched a while back ,and couldnt get it to work .

[DFI pit bull]

Great scores, also I think 21.7k for 06 single gpu is great. Congrats guy's.

[MusicIsMyLife]

Thanks. :)

Lod is set with atitool, iirc it is 27 beta 4. That worked in cf too.




Great scores, also I think 21.7k for 06 single gpu is great. Congrats guy's.

Thank you very much. :yepp:

And yes, 21.7k single gpu isn´t to shabby. :D But we will try to improve this one - like always. :yepp:
