I would like to share my build experience:
Motherboard: Intel DX58SO2 LGA1366, Bios 0779 dated 2011-04-06
CPU: i7-950 3.06GHz 45nm Bloomfield quad-core 1066MHz memory bus
Cooler: Noctua NH-U12P SE2 with 2 x 120mm fans, 3-pins.
RAM: Kingston HyperX KHX1600C9D3K3/12GX, XMP 12GB DDR3-1600 CL9-9-9-27 1.65V kit (3 x 4GB DIMM); 2 x kit = 24GB total RAM.
Video card: Sapphire Radeon HD5450 512MB 64-bit DDR2, passive cooling
Case: Antec P183 V3 (I added 2 extra 120mm fans in middle HDD compartment to cool North Bridge). Top case fan disabled.
PSU: Antec CP-1000, 1000 Watt CPX
Boot disk: Intel X25-M G2 160GB SSD (firmware 2CV102HD) connected to ICH10 in ACHI mode
Data disks: X25-M-G2-160GB SSD, X28-M-G2-80GB SSD, WD 1TB WD10-02FAEX HDD.
Windows 7 Pro 64-bit (without SP1)
Microsoft Security Essential (MSE) anti-virus v2.0 (Virtual-Machine folder excluded)
Intel SSD Toolbox v2.0.2
VMWARE Workstation v7.1.4
Intel Extreme Tuning Utility v2.1
Intel Desktop Utilities v3.1.3
Dataram RAMDISK v3.5.130 (free version)
Romex Software FancyCache for Volume Beta v0.6.1 (using RAM as level-1 cache only; didn't try a SSD as Level-2 cache yet).
No overclocking, all runs at stock speed. The 24GB memory is running at 7-7-7-20 8x memory mutiplier, selected by Auto setting in BIOS.
With all fans set to low speed around 800rpm, expect single Noctua fan set to 1300rpm:
North Bridge temp runs hot: idle 59C, load 63C
CPU core temp: 41C idle, load 100% 15 minutes gives 75C
Above readings are from the Intel Extreme Tuning Utility.
System has been running for about 10 days and all-in-all I am happy with the result, minor gripe is the hot NorthBridge.
Hope above is of use to someone!
No problems with cold boots, or "Restart" (i.e. reboot) from within WIN7.
I am not sure about "Sleep" from within WIN7, however. This sometimes doesn't work, but could be due to my Belkin KVM switch; my screen is blank after i wake-up the system. I am not too bothered, since system boots quite fast from cold start.
I might try with 1333Mhz but a stable system with 24GB ram is more important to me.
In fact the 1600Mhz did work to a point, i.e. WIN7 booted, I re-ran the WEI and this wnet up from 7.7 to 7.9. But when I launched vmware workstation, the system froze. To conclude, more testing is needed.
This is ram I had but never used and just used it in this build. I need the 24G too and I'm looking for the right ram to move into.
Windows 7 Professional 64
RAM: 6 DIMMs KHX2133C9AD3T1K2
video: EVGA GTX580
PUS: Corsair 1200AX
CPU: i7 990x
C:\ drive: intel 520 ssd 120G (sata3), nothing on this drive but operating system
HHD's: 500G/WD sata2 WD5003ABYX (2 drives), 500G/WD sata3 WD5002AALX, sata2 1T/Samsung
OPTICAL: 1 DVD burn, 1 BR burn
The 1333 speed on my ram is the default set by the bios.
I turn the system off every night and restart it every morning. I went through the cold boot problems for a few days and then it settled down and I haven't had any problems with it since (about a week now).
That's a good point. By selecting XMP profile in the BIOS, my voltage was set to 1.6xx volts, the max specs of my Kingston.
I noted that my uncore speed was set to more than 2100MHz.
Do you know if it is possible to lower uncore speed while keeping ram speed to 1600Mhz?
I just ordered 24G of Corsair Vengeance CMZ12GX3M3A2000C10 (2 kits). When I get it in, I'll run some test with different settings and let you know how it goes. I decided on the Corsair because they seem to have a lot of experience with Intel problems and they gave me a 100% guarantee that it would work or they would refund the money without any questions.
