Take a look at Antec Titan 650, it is marketed as a server case but it really is a workstation case. It lacks some server features (intrusion detection) and has audio outs, a workstation feature.

Anyway, this case has plenty of room, and it comes with a decent 650W Power Supply.

I have recently added a BlackHawk; it is kind of a Newegg's own HAF 932 knockoff, but it works and vents well, can't complain. Depends on your demands.

Edit: Memory is at 28:45.

Nice video. So 4 x 4GB DIMMs at 2133 MHz is speed spot apparently with the ASUS boards. Hmmm Sabertooth Z77 or Maximus V Gene...

Stable for 24h now (fresh..., in-place large ffts)
+50mV core voltage
43x101 MHz
Dual channel 2000MHz-XMP-CL9-RAM @ 1818MHz
No IGFX used
Hottest core @82°C with Corsair H100 water cooling and ambient 20°C
Blue screens start at multi >= 44 with "In-place large" ffts, not with "Blend"

Blue screens / errors / warning and temps > 85°C are "No Gos" for me. Will continue testing.

Reason for average value timing peaks is likely to be an IO process I ran.

Dubslow · 2012-05-12, 16:12

Wow... that's a pretty low clock for such an excellent cooler. It's too bad IB is crap at over clocking, despite the lower TDP.

Those numbers do look pretty darn good though.

henryzz · 2012-05-12, 20:45

Anyone know how good westmere was at overclocking? Was it as good as nehalem?

I have a suspicion that we might be in for a run of:
- on tick, new architecture same process reasonable improvement. Overclocks well
- on tock, new process minor improvements. Lower power suited for laptops. Doesn't overclock well.

I wouldn't be surprised if haswell(the next tick) overclocks just as well as sandy bridge.

From the Ivy Bridge wiki page, the reason for the high OC temps:

http://en.wikipedia.org/wiki/Ivy_Bri...rchitecture%29

Quote:

Ivy Bridge's temperatures are reportedly 20°C higher compared to Sandy Bridge when overclocked. Overclockers[who?] speculate that this occurs because instead of using fluxless solder to transfer heat from the die to the Integrated Heat Spreader (IHS), Intel used Thermal Interface Materials (TIM) to cut cost. The thermal paste has much lower thermal conductivity, causing heat to build up on the die.[20][21][22] Impress PC Watch has proven that this is in fact true.[23]

Maybe the immersive cooling techs (liquid nitrogen) might reach higher speeds than sandy bridge OCs.

Lame. Cheapass Intel. I'd rather pay the same price and get the same OC performance rather than have them be $20 cheaper. (To be fair, on the whole, this is probably a win for Intel, as most people don't give a hoot about OC.)

I regarded my high temps with suspicion. I didn't mention before that one of my four cores was >= 5°C hotter than the others. This made me wonder that the cooler wasn't fully functional.
I reinstalled the cooler with new heat paste. All temps went down about 10 to 15 degree.

Now the hottest core shows 72°C instead of 86°C when both GPUs are heated up.
Never trust the pre-glued atomar-thin heat paste. I noticed that 15% of the core area hadn't had any direct contact before... arg.

A piece of glass worked pretty well for me in those days. What were you using?
