I'd like to share my Mufasa build with everyone! While this isn't the most powerful SR-2 build out there, I think a lot of people would enjoy seeing the machine, regardless!
This machine consists of:
• 2 x 6-core Xeon x5650 processors
• EVGA SR-2 Motherboard
• 48GB G.Skill Ripjaw memory
• 1 x GTX 690 GPU
• Thermaltake Grand 1200W power supply
• Corsair Force GT 120Gb SSD
• WD 1TB Red HDD
• Ethernet PCI card
• FireWire 400/800 PCI card
• 2 x Thermaltake Frio CPU coolers
• Lian-Li PC-A76X Case (Not the exact case, but closest match since Amazon stopped carrying the case I used)
Now, here are some pictures:
The parts have arrived! This is always the most exciting part of building a new system!
The SR-2 really is a beautiful board. The PCI slots offer tons of expansion, there's a good number of SATA ports, etc. I only wish there was a higher memory limit (48GB is the max), and the rear I/O could have used a few more options, such as FireWire. The color scheme looks really nice, as well.
I built this system live via my website, so of course, there were a whole bunch of live fails I ended up needing to change the backplate that came on the SR-2 to allow the Frio coolers to fit. Aside from that, the case simply didn't have all that great of cable management. I decided not to go with liquid cooling, as these air coolers were very highly rated, as well as budget constraints (this was a pricey build as it was). Liquid cooling may make its way to this build in the future, though.
I decided to go with a GTX 690 for this build. Although OS X doesn't take full advantage of this dual GPU card, there was going to be some work done on the Windows side of things, which would be able to utilize the GPU more than OS X. With that said, the card would still be able to perform quite well within OS X, plus I got a pretty sweet deal off eBay for a next to brand-new card.
After some hard work out of the case, the system seems to be performing great! The machine posts just fine, OS X can be installed, etc. The Frio coolers blend right in with the black and red color scheme of the board, and even offer a nice white accent with the actual fan. I also felt that blue memory would be a nice accent to an otherwise black and red machine. Once I got the blue memory in there, there were times I liked it, and other times I didn't. More on the memory in a bit.
Well, remember that memory I was just talking about? After putting the machine in the case and tidying up the wires, I boot the machine on, boot into OS X, and what do you know; only 32GB of memory is being recognized. I booted into Windows, and the same thing was happening. This isn't good. Time to do some diagnostics.
After booting it up a few times out of the case, it seemed to boot just fine every single time. This led me to believe that it had something to do with the case. After removing all un-necessary motherboard mounts, the system now boots up just fine! **If you get anything from this post, it's this sentence; always, always remove un-needed motherboard mounts.** After removing the mounts, the system then booted up great within the case! :wink2:
I also decided to go with different memory, which is where the aforementioned G.Skill Ripjaw memory comes into place. This is pretty close to the completed built, but some tests were still being run:
Once all of the kinks were out of the way, I was left with a pretty awesome looking & performing hackintosh! I always loved the look of the Windows CPU meter gadget when under a full load, but with all of these threads, it's better than seeing a real rainbow!
I have some additional videos on my YouTube channel regarding this machine if you want to see some more of Mufasa! I have videos of a tour of the hardware, as well as the benchmarks right below:
Thanks for reading, and be sure to let me know if you have any questions!
Hi guys, I've had someone working to put together a system for me over the last several weeks.
I've now got the machine but as I've been putting it through it's paces we are discovering a few problems.
Just throwing some questions out there as we are both getting to the point of being quite frustrated and any help will be greatly appreciated!
Now just to clarify, I didn't build this machine myself but have been helping to sort out quirks as they arise. I'm probably capable of trying out most fixes but anything a bit over my head I'll pass on to the builder to carry out. Just trying to save a bit of time if I can do some things my self seeing as the machine is at my place. We've also been at it pretty much full time for nearly 8 weeks.
These are the specs (any other info you need just ask & I will find out):
EVGA SR-2 motherboard
2 x 6 core Xeon 5679 3.2GHz (12 core/24 thread)
32GB ECC RAM (4 x 8GB)
GTX570 MSI twin frozr II
OCZ Agitlity 3 240GB OSX system drive (6Gb/s data connection)
OCZ Agitlity 3 120GB Windows system drive (6Gb/s data connection)
Noctua DH14 coolers
Ethernet adapter (PCI-E Slot 5)
Areca 1213-4i RAID card (4x2TB WD black RAID 5) (PCI-E Slot 6)
FireWire 800 adapter (PCI-E Slot 7)
Sleep and related performance issues
I get pretty low geek bench scores of around 18,000 before sleep, which then go up to around 24,500 if the machine is put to sleep then woken up again. Cinebench CPU and GPU benchmarks also increase quite a lot post-sleep, OpenGL scores can be as low as 11fps pre-sleep and 30fps or more post-sleep. The scores are also not very consistent pre-sleep.
I am not able to wake the machine from sleep at all if any overclock settings are applied. I planned to run the machine permanently at a mild 3.6GHz but it enters a cycle of attempting to power on. Fans spin up for a few seconds, then it dies and repeats the process every 5 seconds or so.
It has also happened a few times with no over clock settings applied, when sometimes the fans spin permanently but nothing else happens.
Firewire is not detected/functioning before sleep but works after sleep.
Every time the machine fails to wake from sleep, or I need to restart the machine for any reason, the BIOS settings randomly reset. I need to go in and adjust the AHCI, power management settings etc. almost every time. Sometimes it will takes several attempts for the settings to stick before it will boot successfully.
So thanks for reading if you got this far, I believe this machine has great potential and really want to get it going!
I'm interested in building a Hack Pro with an SR-2 + dual 5649s.
I'm pretty sure one can, with a lot of work, properly fit the gigantic SR-2 with GPUs, HDDs, SSDs, PSU, cooling etc. inside a G5 case. Pretty sure I've even seen modded G5s with SR-2s inside somewhere on the net.
But what about the Mac Pro case. It seems a bit tighter: http://i45.tinypic.com/6tnzeu.jpg compared to the G5: http://i50.tinypic.com/72r8sk.jpg
