Xeon W3520 @4877Mhz H20

Categories: CPU Overclocking, Overclocking | no responses

Been playing with my new Xeon W3520 cpu and managed to break alot of personal best benchmarks for max validation, max uncore frequency achieved, Super Pi 1M, 32M and Pi Fast on DFI UT X58-T3EH8 with just regular water cooling :)

  • Super Pi 32M HT Enabled max = 4677Mhz at 1.488v
  • Super Pi 32M HT Disabled max = 4794Mhz at 1.552v
  • CPUZ Validation HT Disabled max = 4877Mhz at 1.584v
  • Max Uncore Frequency = 4760Mhz !

System:

  • Intel Xeon W3520 3845A935 D0 (Xeon equivalent of Core i7 920 D0)
  • EK Supreme LT 1366 / FESER 480 / MCP655
  • DFI UT X58-T3EH8 04/28 beta
  • HD4870x2 (HIS 4870X2 to Asus Top bios) with ATI WinXP 9.5
  • 6GB Corsair Dominator GT DDR3-2000Mhz 7-8-7-20
  • 750GB Samsung SATAII
  • Silverstone OP1200 PSU
  • Triple boot – WinXP Pro SP3 / Vista Ultimate 64Bit SP2 / Win7 Ultimate 64bit RC

Max Validation @4877Mhz at 1.584v

Uncore Frequency @4645.6Mhz

Super Pi 1M & PiFast @4802Mhz at 1.584v

Super Pi 32M @4794Mhz at 1.552v

Super Pi 32M @4677Mhz at 1.488v

Max Bclk Validation

So far 235bclk is max for validation. Messing with voltages to see if I can get more



Uncore frequency = 4663.5Mhz

Uncore frequency = 4707.8Mhz

Uncore frequency = 4760.2Mhz

Not bad for a water cooled W3520 cpu :)
