J.Lin - 4x Radeon HD 7970 @ 1480/1910MHz - 84669 marks 3DMark Vantage - Performance

[Guest John Lam]

Download the newest BIOS 1406 for Rampage Extreme, Performance will increase about 0.5~1% in 4 Way Crossfire.

Great job man...and awesome way to bench 4 way

[Guest John Lam]

Do you like it ? LN2 Chilled WaterCooling for 4 Way VGA , the liquid suppport up to -36C , GPU and GDDR Temp is very stable to keep in -5~-10C.

[Xtreme Addict]

i like it

[Guest John Lam]

Thank you , Xtreme Addict!! I saw your record in MOA !! I would like to join but I have no MSI MB and VGA.......

[K404]

1480MHz at -10 is very very nice! Are these cards using the new silicon?

 

Get that new BIOS bro, you will hit the 85K milestone!!!

[Guest John Lam]

K404 , XT1 Chips Only , I will try XT2 later

 

GPU ad GDDR chips works well in constant temp, I have 2 card can pass 1580MHz in 2 Way CrossFire mode.less card and cooling performace will increase. single card can down to -36C.

 

 

This is "Tin Shui Wai" Rev 4 , I make fastplug design and choose how many card I want to use, It support NVIDIA GeForce 6/5/4 and Radeon HD 5/6/7000 Series, is it funny ?

[Guest John Lam]

 

See that's is very cool when benching 3DMark 11.

 

 

The Measure point at the top is the liquid after cooling the GPU, Card 1 2.4C / Card 2 2.8C / Card 3 3.3C/ Card 4 4.2C When running Unigine DX11 ,After pass 4 Card , Liquid will back to Kignpin F1 again, the temp will drop to -18~20oC.

 

I have make some change already , the system I show in Computex 2012 , but I modified again and starting the next project called "Hung Shui Kiu", performance increased 35-40% compare with "Tin shui Wai". but I need to study what type of liquid is better than "Benz's Coolant".

[Andrix85]

Great setup J.Lin.....Your idea is very efficient!

[Guest John Lam]

I hope everyone can focus in my cooling design, the next gen LN2 Chilled WaterCooling "Hung Shui Kiu" need to solve a lot of people, the first problem is liquid . If anyone have some idea for my project, please let me know....

 

Also , I don't have hwbot forum account right now , feel free to leave a message in facebook.hkepc.com .

 

I really want to buy one or two more "Kingpin F1" for research , but the price is so high .......HAHAHA

acetone will also work but it evaporates quickly and is pretty corrosive.

[subaruwrc]

where can I find BIOS 1406 for R4E ?

[bynext]

you can use 50% Ethylene glycol with distilled water and can go until -34°c.

Hi, J.Lin, congrats on the record.

 

OT: It would be nice if you could give HIS GPU a mention in the GPU Type list, Think HIS deserves it and would help them out also. thanks

The minimum freezing point is observed when the ethylene glycol percent in water is about 70%,you can go until -51°c.

[subaruwrc]

what temp for the cpu ?

[Guest John Lam]

-30 ~ -55C , SB-E has Cool bug

[subaruwrc]

great cpu. mine can reach " only " 5.5ghz max, but i cannot unleash its full potential yet. can u give me some hints on vantage ?

[Guest John Lam]

For Vantage, CPU Freq is very portant,5.5GHz is not enough to win this battle , also you need to know how to tweak in CCC , the GPU/GDDR Eff Ratio...etc.

[Tonim89]

I would like to see some of these 7970 with dual xeons 1366. This setup could get the WR easily.
