Max BCLK Super Pi 32M Benchable
Did a fresh hard drive install which is WinXP Pro SP3 & Windows 7 beta dual bootable before attempting max Super Pi 32M benchable Bclk frequency tests. This time with 3x1GB Samsung HCF0 based modules for triple channel :)
System specs

- 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 - 01/06 beta bios
- 128MB Gainward FX5200 PCI
- 2x1GB Corsair DDR3-2133C9DF Dominator + 1GB G.Skill PC3-12800HZ (3x Samsung HCF0)
- Ram cooling: 3x 60x25mm Sunon 23.5cfm Maglev fans
- 80GB Hitachi 7K80 SATAII
- Pioneer DVD-RW
- 1KW Corsair HX1000 psu
- WinXP Pro SP3 full nLite updated hotfixes / Windows 7 beta dual boot
Triple Channel CPUZ Validation @229Bclk
Haven't pushed ICH 1.5 Voltage yet like I did for 230Bclk, so that will be next up for testing.

QPI Frequency = 4123Mhz!

Super Pi 32M
Ignore the times just testing with loose timings. Higher Bclk do require more vdimm that usual due to QPI ceiling. Without enough vdimm DFI post diagnostic LED = CF code for lack of vdimm voltage.
@226Bclk bios set - QPI Frequency = 4063Mhz

@226Bclk setFSB windows set - QPI Frequency = 4074Mhz
http://fileshosts.com/intel/DFI/DFI_...9m00s468ms.png
@227Bclk - QPI Frequency = 4088Mhz
http://fileshosts.com/intel/DFI/DFI_...8m57s750ms.png
@228Bclk - QPI Frequency = 4110Mhz
- had to bump vdimm, vcore and CPU VTT Special percentage added
- either a bad run, or lack of volts for either vdimm or CPU VTT or both led to slower 32M Pi time ?
