Cool Intel Core 2 E6750 + Asus Blitz Formula SE Adventure

Intel Core 2 Duo E6750 + Asus Blitz Formula SE Results

Six weeks ago the news was out that Asus were releasing their R.O.G. series of Intel P35 chipset motherboards with special features such as Crosslinx allowing 8x + 8x Crossfire, Voltiminder LED, Fusion Block System, Load line calibration, CPU Level Ups, LCD Poster and more importantly for us memory enthusiasts - 2 phase DDR2/DDR3 circuits (each phase shares half the the load providing more stable power to memory). Today will look at the Asus Blitz Formula Special Edition motherboard from the R.O.G. series. The Asus Blitz Formula comes in 2 versions both which are DDR2 only - a regular northbridge heatsink version and a Special Edition which has Fusion Block System northbridge cooling)

Photos:
  • Full motherboard photos can be found here.
  • Bios screenshots can be found here.

Some bios/voltage setting highlights:
  • FSB: 200-800FSB
  • PCI-E: 100-150Mhz
  • CPU Voltage: 1.10000v to 1.90000v
  • CPU Voltage Reference: 0.531x to 0.635x
  • FSB Termination Voltage: 1.20v to 1.80v
  • Northbridge Voltage: 1.25v to 2.03v
  • Northbridge Voltage Reference: 0.61x and 0.67x
  • DRAM Voltage: 1.80v to 3.40v
  • Southbridge Voltage: 1.050v to 1.225v
  • PLL Voltage: 1.50v to 2.00v

Asus Blitz Formula Information & Downloads

Flashing bios on Asus Blitz Formula:

Asus Blitz Formula uses 2MB sized bios flash ROMs. So best way to flash or update your bios on Asus Blitz Formula is to use a USB flash drive and the motherboard's own inbuilt EZ Flash 2 function:
  1. Put bios on USB drive
  2. Ensure USB legacy is enabled and boot into bios
  3. Use EZ Flash 2 in bios to select the bios on your usb drive.
  4. Follow prompts to flash and wait until the auto reboot happens.
  5. Sometimes it may not boot up straight away, so turn off system, clear CMOS and you should be up and running again.

User Notes:
  • Seems the Asus Blitz Formula dimm slots are designed like Asus P5K Deluxe where the white dimm slots - DIMM A2 + B2 dimm slots allow memory to overclock a little higher.

Re: Intel Core 2 E6750 + Asus Blitz Formula SE Adventure

@3800Mhz - 8x475FSB 1:1


Here's where the cpu vcore voltage jumps up somewhat, 1.55v bios set for Super Pi dual 32M capable and 1.625v bios set for at least 8 minutes of Prime95 small ffts load testing. Room temp rose from 20C to 25C for these tests compared to last nights tests.

Re: Intel Core 2 E6750 + Asus Blitz Formula SE Adventure

E6750 G0 ES - max FSB tests
Asus Blitz Formula


Did some quick max FSB tests and basically for this E6750 ES G0 it's same as on Asus P5K Deluxe 0311 bios around 490FSB and 495FSB with some CPU PLL voltage + NB voltage tweaks to boot from bios into windows. I believe this particular E6750 is hitting an FSB wall as 500FSB seems out of reach for straight boot from bios into windows.

The extra CPU PLL voltage above 1.80v helps on Blitz Formula compared with P5K Deluxe. On P5K Deluxe max boot from bios into windows was 8x493FSB with 1.8v CPU PLL Volts. On Blitz Formula CPU PLL Volt set at 1.84v allowed 495FSB to boot from bios into windows so far. But haven't done any extensive testing of voltages to see if I can squeeze any more FSB out of this E6750 ES G0 cpu.

@8x493FSB at 1.6375v bios set with 1.7v CPU PLL Volts
Boot from bios




@8x495FSB at 1.6375v bios set with 1.7v CPU PLL Volts
setFSB in windows from 493FSB to 495FSB

Re: Intel Core 2 E6750 + Asus Blitz Formula SE Adventure

E6750 G0 ES - 4:5 divider
Asus Blitz Formula


Jumped straight to 4:5 divider and 8x490FSB and shoved some serious voltage into the system to pull this of





612mhz 4-4-4-9 was with exactly what is reported by Asus PC Probe2 = 2.72v vdimm. Surprisingly the Blitz Formula reports pretty accurate vdimm voltages from bios to PC Probe2. The only voltage with variance is vFSB volts... i.e. 1.28v vFSB bios set = 1.30-1.31v PC Probe2.
