Corsair Powered - i7 920 @4610Mhz


Recommended Posts

Thanks to Corsair for the 2133C9DF kit and HX1000!


Finally took off the training wheels for DFI UT X58-T3EH8 after having the motherboard for past 7 days, I'm starting to get the hang of things :D:


My first Super Pi 32M bench at sub 8min with Core i7 3836A756 on Thermalright Ultra 120 air cooling!


Had to turn off Hyperthreading to reduce the heat output and had to go back to dual channel kit, 2x1GB Corsair DDR3-2133C9DF Dominators as it's only memory I have capable of up to DDR3-2200Mhz Super Pi 32M stable.


With HT off, load temps were around 74-86C. Powermate wattage meter read ~290 watts idle and 305 watts load for Super Pi. I tried running Everest benchmark report (all tests) and measured ~530 watts load drawn from the wall but system rebooted @4610Mhz :D:


For comparisons sake, at 20x133 = 2.666Ghz stock, Powermate wattage meter reads around 125 watts idle with FX5200 PCI video card installed.


Room temp = 24.5C


System specs

  • Intel Core i7 920 3836A756
  • Thermalright Ultra 120 Extreme + LGA1366 Bolt Thru kit + 2x 120x38mm Scythe UltraKaze 2000rpm 87cfm fans in push/pull
  • DFI LP UT X58-T3EH8 R.A51 - initial first release 12/18 bios
  • 128MB Gainward FX5200 PCI
  • 2x1GB Corsair TW3X2G2133C9DF Dominator 9-9-9-24 at 2.0v rated (Samsung ICs)
  • Ram cooling: 3x 60x25mm Sunon 23.5cfm Maglev fans
  • 750GB Samsung HD753LJ
  • Pioneer DVD-RW
  • 1KW Corsair HX1000 psu
  • WinXP Pro SP3 nLite fully updated




First 32M run 21x217BCLK - so close to sub 8min!






I nearly managed to boot into windows to take screen shot at 21x221 = 4638Mhz, but guess either heat or BCLK ceiling was being reached. So settled for 21x220 = 4610Mhz :)

What were your temps on air running 4.6Ghz at 1.65v? If it ran in Turbo mode presumably it was below thermal design parameters. Was the NB and and power also hot (I think the Volterra is self protecting).


From your result, could it be assumed that a 940 could have hit 5Ghz?


Did running dual channel rather than triple channel help? What restrictions did it remove? Did it impair the overal system performance? That is, would 3x1866 been quicker than 2x2133, even OC'd to 2200?
