I didn't notice flexing if there is any. The mainboard is well anchored to the Cosmos II. For example, I can confirm there are several screws (a dozen or more) involved when screwing down the MSI Big Bang X-Power II, which is an extended mainboard. The Notua mount is also amazingly strong even though there is no back plate involved with its installation.

Thank you for the benchmarks...can't wait for the remaining ones...could you also run a Vantage test?


Wish you the best,and hope you dont have any trouble with the pc for the time coming.

You are welcome; here are the other benchmarks you requested.

Regarding trouble, I have my fingers crossed most of the time-- and I put on a grass skirt each week to make a sacrifice to our local Volcano God of Computing, just to hedge my bet...

Migration to 3-Way SLI with EVGA GeForce GTX TITAN


Despite recent AMD driver improvements, the XFX Radeon 7970s in CrossFireX are rather loud under heavy load, and a bit of stutter remains in some games. For example, Battlefield 3 multi-player (64) pegs both GPUs at maximum quality rendering at 2560x1600. Simply put, the minimum frame rates at this level just aren't good enough. Overclocking the cards simply generates even more heat, more stutter and produces even higher noise levels.

Moreover, it is taking Adobe way too long to fully support Radeon hardware in Premiere Pro and other CS6 applications. The lack of hardware video editing support for Radeon 7970 is ridiculous, and I'm just tired of waiting.

Therefore, the 7970 hardware is being replaced with three EVGA GeForece GTX Titan video cards, which should resolve these issues and leave a good amount of headroom for even higher multi-planel resolutions and next-generation gaming engines coming down the pike:

Beastly choice my friend! Still going to keep the GPU's air cooled I'm assuming? Looking forward to more pics of the updated system.

Yes, I will retain an air-cooled configuration for now. Perhaps some day, whenever future applications force my hand, I will actually need to seriously overclock the CPU and GPUs. Whenever that day arrives, I will probably opt to re-configure the entire existing setup using water instead of air prior to pushing everything higher up near the melting point.

Besides the 7970s pegging under heavy BF3 gaming load, there just isn't any other bottleneck worth mentioning at this point.

I will post some of the migration work from 2-way CrossFireX to 3-way SLI later next week. Two of the Titans arrive together on Monday, and the third card from NewEgg should be here next Wednesday. NewEgg only allows the purchase of one card per household...

TITANIC UN-BOXING

All three GTX TITAN cards have made it in, shipped from two different sources: NewEgg and Amazon. NewEgg has a single-unit-per-household limitation but Amazon doesn't, so one card came from NewEgg and the other two were sourced from Amazon.








I apologize for not removing the cards from their anti-static bags, but I'm not going to do that until right before I actually install the hardware this weekend.

My initial impression is just how heavy the card feels, very solid. The packaging by EVGA is top-notch, with the card surrounded on all sides by thick, custom-fitting foam. There is no doubt the boxing will remain in storage just in case this hardware needs to be transported again.

The warranty registration process with EVGA is somewhat involved, but the website is nicely done and everything worked smoothly. I decided to extend the warranty to 5 years and include advanced 2nd-day RMA service to ensure prompt cross-shipping and minimize down-time.

TITANIC INSTALLATION

All three GTX TITAN cards are operating well together in SLI.

Thankfully, the migration away from CrossFireX to 3-Way SLI went smoothly. After uninstalling the AMD Catalyst driver and shutting down, the former XFX Double D Black Edition Radeon 7970 cards were removed.

The only complicating factor when installing the three TITAN cards was providing a third PCIE power cable with 6 and 8-pin connectors from the Enermax PSU. The MSI Big Bang XPower II mainborad and Cosmos II case are both very large, offering excellent clearance between components. Air flow is also good, especially in the GPU area. There is plenty of room to work inside the case and it does not look overly crowded even after installing all three TITAN cards.

I am hoping this configuration will provide good thermal performance. Benchmarks will be taken next after the initial NVIDIA driver setup and EVGA Precision configuration process is completed...

Temperature Benchmarks


The new TITAN 3-way SLI setup has lowered temperatures across the board compared to the former HD7970 CrossFireX configuration in terms of overall Cosmos case, CPU and GPU temperatures. The primary reason for this drop is a major difference in GPU cooling design: The TITAN design pushes most heat out the back of the case, but the XFX Double D/Ghost design exhausts most of the heat into the upper main chamber.

Two upper/lower Cosmos 2 chambers are monitored for temperature. The main upper case chamber temperature is 22.4C at idle, 1.4C above the ambient room level. This is .5C lower than the CrossFireX setup, which was 1.9C above ambient. The smaller, lower chamber temperature is 21.5C at idle, .5C above ambient; the CrossFireX setup produced exactly the same performance. Under 100% folding load (3960X CPU and all three GPUs) the upper chamber temperature is 23.5C, 2.5C above ambient. This is 4.2C lower than the CrossFireX setup, which was 6.7C above ambient.

At idle, the 3960X CPU averages 38.2C across all 6 cores with the new TITAN setup, 52.8C away from Tj Max. This is .4C lower than the former CrossFireX setup, where the CPU idled at 38.6C with a Tj Max delta of 52.4C. Under 100% folding load, the new TITAN setup averages 64C across all 6 cores, 27C away from Tj Max. This is 5C lower than the CrossFireX setup, where the CPU was fully loaded at 69C with a Tj Max delta of 22C.

At idle, the TITAN setup averages 30.3C across all three video cards. This is .3C higher than the CrossFire setup, which averages 30C between the two HD 7970s. This area was the only measurement which favored the CrossFireX configuration. The slight rise in average idle temperature can be accounted for by the slightly higher idle clock rate (324MHz versus 300MHz) and more restricted card clearances in the 3-way SLI configuration.

Under 100% folding load, the TITAN setup average 59.3C across all three cards clocking at an average boost rate of 1040.6MHz . This is 6.2C lower than the CrossFireX setup under the same load, averaging 65.5C between both HD7970s while clocking at 1000MHz. This is impressive given the tighter 3-way card configuration and the slightly higher TITAN clock rate.
