Cool 4/28 Beta Bios results - DFI UT X58-T3EH8

Been playing with DFI's latest 4/28 pre-public beta bios and it seems to have improved memory clocking stability for Elpida IC modules as well as improved my max H20 cooled bclk validation from 233 on 3/28 pre-public beta bios to 235bclk on 4/28 bios.

4/28 bios seems to be more tolerant of very tight subtimings .. so close to sub 9min 32M pi at <3900Mhz!



sub 4000Mhz 32M

Starting to hit probably thermal limits of my i7 920 3836A756 on H20 cooling as 32M Pi seems to be topping out around 4680mhz with HT disabled. Only managed to shave ~1 second off my best 32M pi time with i7 920.

Did 2 runs on fresh Win 7 64bit RC install I did last night. Only change was CPU VTT voltage needed to pass Hyper Pi 8x 32M vs 4x 32M.
  1. 8x 32M Hyper Pi HT Enabled - CPU VTT = 1.44v
  2. 4x 32M Hyper Pi HT Disabled - CPU VTT = 1.47v needed more for 4x32M HT Disabled

RTL value for channel A changed when CPU VTT changed from 1.44v to 1.47v

RTL A/B/C = 56/57/58


RTL A/B/C = 55/57/58


Past bioses and tests, I found memory bandwidth in memtest86+ v2.11 was higher with HT disabled than HT enabled, so could explain why more CPU VTT volts is needed for HT disabled.

4//28 looking sweet indeed 8x 32M Super Pi instance via HyperPi @DDR3-2080Mhz 7-8-7-20 1T at 1.725v bios set vdimm = 1.730v real DMM vdimm.

Both cstkl1 and my DFI contact suggested with 4/28 bios, I check out setting BOOT Up CPU Base Clock to around 180-185bclk for better perrformance and stability. Seems to work as first test has me reducing my required CPU VTT volts from 1.43v to 1.37v for 8x 32M Pi test!!!!





* BCLK/UCLK/QPI Controller Settings *
QPI Control Settings: Enabled
QPI Link Fast Mode: Enabled
QPI Frequency: AUTO
CPU Base Clock (BCLK): 200 Mhz
Boot Up CPU Base Clock: 185 Mhz
PCIE Clock: 104 Mhz
DRAM Frequency: 10x Memory multipliers
UnCore Frequency: 20x Uncore multipliers
Bumped CPU VTT from 1.37v bios to 1.39v bios and IOH/ICH v1.1 from 1.11 to 1.13v for Linx stability

There is no autoexec with this download. Also there is a changelog with it. Should I delete the changelog and use a autoexec with it or what? I'm confused.

I just use bootable usb drive with AWDFLASH and type this command once booted

Code:
AWDFLASH LX58D428.BIN /cks/sn/py/cc/cd/cp/ld/qi/WB/ch
Or just edit your old AUOEXEC.BAT and change bios file name
