Testing "Grosse Bertha"... xD [E6600@5.1GHz, X6800@5.4GHz, DFI Infinity P965-S, etc.]

WTF is "Grosse Bertha"?

Few tests have been performed since Monday. Luigi's first charges were very good... but we wished for coldest temps.

We get -115C loaded evap during Spi 1M with my X6800 operating between 5200MHz to 5250MHz and 1.81V DMM. Only 1 degree lost between idle and Spi 1M, and 4 to 5 degrees between idle and Spi 32M. AFAIR HP were = 15bars in 2nd, and = 3bars in 3rd.

It was quite good but not enough... (don't look at times, just testing here not benching )
On Wednesday, we tried it after a dinner with some friends, boblemagnifique, umbre_tombetoile and koda. Both 2nd and 3rd stages were severely overcharged so we get -109C loaded evap with bob's E6600 L630A at about 5.1GHz @1.79V.

Finally, some R1150 was removed from 2nd and 3rd stages but we weren't able to try it loaded because of a matter with the huge 3rd stage cp. :o
Today, I've continued with my X6800 @1.81V.

Screenies speak for themselves...

Let it be known, evap temp was -111C during Spi 32M at 5.1GHz. Also, evap temp was -121C (-122C speedfan) idling at 2.9GHz@1.47V.

I assume you have understood what "Grosse Bertha" is...

I'll post some fresh pics ASAP... Thanks for reading

PS: Thank you Luigi for all you've done! This guy has done a heck of a job.

That's incredible my friend! 5.2 on a cascade, and 5425 suicide...wow, I really gotta step up to the plate here. Great to see it in action now, you and Luigi must be very proud. A machine so many of us would dream to have...

afireinside · 04-19-2007, 03:35 PM

Now THAT is a cascade

I can't wait to see pictures of it. Killer clocks for "only" cascade.

ojdr2001 · 04-19-2007, 03:49 PM

Grosse or "sexy" Bertha??

Amazing machine..... congratz

MADMAX22 · 04-19-2007, 04:03 PM

WOW great temps on that thing, and just perfect since arent c2d cold bugged at jsut lower then that (or do i have my numbers messed up)

aewsome work

LittleDevil · 04-19-2007, 04:39 PM

Really nice results my friend

regards

LyP0 · 04-19-2007, 04:40 PM

grosse berhta means big bertha. grosse is big in german. It was supposed to be some sort of huge cannon.

congrats on the sick clocks on cascade man, verry nice.what's the delta temp idle and load ?

JT from Russia · 04-19-2007, 05:40 PM

Really nice results

Keep on

m0da · 04-19-2007, 06:02 PM

holy. grosse (i get it, large/fat) bertha. nice.
you can call it sick bertha, cause that is some sick performance yo.

LordofDoom · 04-19-2007, 06:12 PM

Damned nice.

andre X_X · 04-19-2007, 09:14 PM

OMG.. that 3-stager looks evil

blind_ripper · 04-19-2007, 09:33 PM

hehe nice work before , the name make's me think of my first dice container fat bertha

look forward to some nice SPI times from u

GG before and luigi

hehe

It s also on a cascade (3 stages made by skirms_fr )
evap @ -120°

Thx guys

@LyP0: It was a canon during WW1

Delta is 2C on evap at 5.2GHz @1.8V during Spi 1M, and 6C during Spi 32M at 5.1GHz @1.8V. BTW 2nd stage requires further tuning.

@Pt1t: Yea, it's a very impressive unit. AFAIK it needs a little more tuning for big loads anyway.

So; I've done my first try on DFI Infinity P965-S motherboard today. I need to find a way to use clockgen because I can only get the CPU operating at boot clocks.

http://valid.x86-secret.com/show_oc?id=189123

Not very fast for 5.212GHz

But it's 1:1, and I need to learn how to tweak the board more.

I didn't try it more because the board insulation wasn't very good...

Nice clocks before! Your "bertha" is a beast!

before · 04-20-2007, 12:41 PM

Thx

Some pics; I'll buy armaflex or something equivalent to finish insulating.

wtkprol · 04-20-2007, 12:56 PM

I want one.

before · 04-21-2007, 05:42 AM

Not the max because CPU-Z and clockgen can't work together :o

Strange

...have you find out why it cant work together?

SetFSB?

since last update of cpu-z, it isnt possible anymore

Mine ...use cpuz 1.3.9 it still work

..

Cupcake · 04-21-2007, 02:22 PM

WOW , That is one damn nice cascade

Its a shame clockgen and CPUz dont work together anymore though

Misko · 04-21-2007, 02:24 PM

Great work as always Xavier

before · 04-21-2007, 03:07 PM

Thank you guys!

@Gautam: No; unfortunately, setfsb (at least mine) doesn't work with the DFI P965-S

I've insulated the cascade more today, and 2nd is now very powerful...

BTW 3rd stage isn't yet tunned for heavy loads such as Spi 32M.

Today's best on P5B-Dlx...

Cascade WR? So close to 5.5Ghz...

And two nice Spi 1M...
