why cables running across the RAM? are the cables too short to run them though a cut out at the top of the board?

good luck with the builds, hopefully not too many returns are needed redface.gif

I've changed a couple things since I took the first batch of photos.

It was my first time using a Corsair 550D case (which I absolutely love. That case is really nice for a mid-sized case. The fit and finish on it is EXCELLENT. I wish it was just a little taller, so I could put the radiator on other builds in "push/pull", but other than that, I love it.

It is also my first time using the Kraken x60 system. Aside from a minor issue with the back plate on LGA 1155 (which does work, it just is a little cockeyed), that too is a good system. I got the OS installed on one of the machines and loaded up the Kraken software and Real Temp and at idle, it stays at 19-20C! I ran Folding@Home on it for about 10 minutes and the temps only got to 40C. Now granted I haven't done ANY overclocking yet, but those are some pretty sweet temps for an all in one system that took all of a couple minutes to bolt on (once you figure it out).

So, having said that, I ended up changing the fans around in the build from the photos. I mounted the radiator directly to the top of the case and put the 2 140mm fans below the radiator blowing air out of the case. So the 2 case fans in the front of the case are sucking air in to the case, and the air passes through the case and out the top. There is also another 120mm fan on the rear of the case that is currently blowing air out of the case, but I *might* change that so it draws air in (and if I do that, I'll get a magnetic filter for it) and see if that helps.

As far as the cable running across the motherboard, that too has changed. The 8-pin CPU power cable was just a bit too short and I just did that to get things up and running quickly. I went down to Micro Center today and got 4 6" extension cables and routed the cable behind the back of the case. I also dressed up all the wires a bit and it looks really clean now.

Just a question, why are you installing Windows 7 on the machines instead of Ubuntu for SMP only folding? Ubuntu gives better PPD and doesn't even require a hard drive to install, or a disc drive.

Well, for 8 hours a day, these machines have to be used at my office, and until I can get 2 programs that we MUST use ported to Linux, I am forced to keep using Windows. These machines are replacing older Pentium D's running Windows XP. Until that time, I will just have to "make due" with Windows 7 (there is no way I'm going to install Windows 8 either).

Trust me, I would love nothing better than to convert my entire office over to Linux for day to day operation. We are ALMOST there. I am in the middle of upgrading our accounting package from a system that is "Windows only", to Sage 300 (aka Accpacc), which will run on Windows or Linux. I just have to find replacements for our CRM package (which I think I can do, but it has to be able to be tied to our help desk application) and our help desk manager software.

I've thought about making 4 USB sticks that I could just pop in at the end of the day, reboot, and boot up in a stripped down Linux build and Fold off that, but that has issues too (like if I'm on the road or someone needs to remote in during the weekend or such). By staying in Windows, I can use the built in Windows 7 scheduler system and automatically start and stop FAH so that it runs after the office is closed and stops when it opens M-F and 24/7 on the weekends. If someone needs to remote in, they can easily, and can just stop the program if they need it.

That's a good idea with the schedule though. Hope you can convince your colleagues to switch over to Linux though, for both their gain and your gain. tongue.gif

I already have my machine doing that and it works nicely. I might do some messing around on these systems and install a Linux VMware build on each of them and use the scheduler ... that will help by about 20% over just Windows FAH alone. I've done the VMware trick before but never in conjunction with scheduler.

Well, time to stress test the first 3770K and see how that Kraken x60 works. What better way than to load up a fully patched OS, a couple utilities, and a Folding@Home client.

Much to my suprise, the Kraken x60 really keeps that CPU cool. At stock speeds, it runs at about 19-20C for general applications (web surfing, mail, etc). When Folding at 3.5GHz, the temperature only went into the low 40's. So it's time to throw in a moderate OC of 4.4GHz @ 1.300V as a good starting point (I know that voltage is way high, but I really want to get them going at 4.6 or 4.7GHz and with 1.300V, that should get me to 4.5 or 4.6 if it's a good chip).

Very nice... And know to wait for the results to see if youve won the silicon lottery...

Here is a shot of them all built up and starting to load up Windows 7 and the other apps.




The one on the lower left is one of the 3770K's that has been on for almost 3 days now. It survived 18 hours at the 4.4GHz @ 1.300V overclock without a hitch. At 100% load while Folding, it ran right about 65-70C at the highest (Core #2 is still the hottest by about 5C ... I might have to reseat the cooler), so now I bumped up the speed to 4.5GHz @ 1.300V to see how it runs.

I did run in to one of the oddest things thought. On one of the rigs, it when I powered on the unit from the front panel, it would start up, then stop, and I'd have to power off the PSU. It never would fully start up. To make a long, frustrating, story short ... it turns out that the motherboard has the "Power Switch" connector with a + pin and a - pin. The 500D case doesn't say which is plus and which is minus (not that is really should matter for a dry contact closure switch) and 3 of the builds had the connection one way and the "trouble child" had the connector flipped. By simply flipping the connector 180 degrees, it roared to life. In nearly 30 years of building my own rigs, I've never ran into such an issue with a case power switch.

Anyway, back to formatting up the rigs and installing apps. thumb.gif

Nice project
good numbers with the Kraken thumb.gif

big upgrade from the P4's

Another 24 hours and no failures ... so up to 4.6GHz. biggrin.gif

So far, even at 4.6GHz @ 1.300V that Kraken x60 is keeping the CPU at under 70C at 100% load.

I must say, I am really impressed with the Kraken. It was super easy to install, and for only having 2 140mm fans, it is doing an INCREDIBLE job at keeping the system cool and best of all, quiet. I highly recommend it if you don't want to fuss with a custom loop and only plan on doing CPU cooling.
