good or bad idea: 5.5K euro for machine 2xTitanZ

[glimpse]

Anyway, maybe we should start another new thread about cases, if there is not one already.

please participate adding a case if You have some particular model in mind =)

Hi,

It's xmas and just unpacked.

I posted on Glimpse's thread about cases:

Man it's beautiful!!! Congrats =) & the spacing for GPUs is perfect!

Waiting for numbers, Rappet! Especially TitanZ vs other cards! =)

Oh Man, I love it! Perfect solution for spacing. Give us scores for Z.

That's a beaut Rappet! And your airflow looks good. I'd also like to see some scores when you get to it.

hi Rappet,

do you have installed 3 Titan Z inside the Cosmos II?

[glimpse]

do you have installed 3 Titan Z inside the Cosmos II?

nope, it's two Blacks + Z =)

Rappet, (regarding to airflow concerns on other, case thread)

Shouldn't You be able to remove these vertical parts that in You path of airflow from front? ..
It seems from pictures that at least the one with extra fan near Your GPUs is removable =)
(I'd probably use dremel if not =p) really curious about performance =)

I installed two fans on the Cosmos II door.

Hi gabrielefx

hi Rappet,
do you have installed 3 Titan Z inside the Cosmos II?

It is possible with the MB chosen: MSI X99S Gaming 9 AC.
You can see (photo I posted) that I have two slots open beneath the Titan Black's.
I was thinking of the possibility of 3 TitanZ, but I already had the Titan Blacks in other PC I wanted to use for this one... and moneywise I did not want to spend another 3K
And now I have a config with pretty optimal airflow around the cards.

I installed two fans on the Cosmos II door.

I might install the second fan later, but then the GPU-powercables might push (into?) the fanblades... that's why I want to see how the config works being on the safe side.

cheers

Hi guys,
Finally I got some numbers on TitanZ

Firstly I have to say that the case with the fans is magnificent.. quietly and keeping the temps on target temp 83 degrees easily. (fans used are the Scythe Slip Stream)
I did not do overclocking... it is just out of the box and render
Octane and also in the tweaking software sees the TitanZ as two GPU's seperetaly (I am using EVGA Precision X) I can tweak and monitor the TitanZ as two seperately GPU's.
note: the order of the GPU's is a bit strange in Precison X: (B-Z-Z-B, while having B-B-TitanZ in slots)

OK, now the numbers with Octane 2.10 PT:
TitanZ : 15.94 Ms/sec
2x Titan Black: 16.12 Ms/sec (on my other machine it was 15.03 Ms/sec)
TitanZ + 2x Titan Black: 30.75 Ms/sec (still with 83 degrees temp and appr 2200rpm on fans quitly!)

cheers
