400FSB BIOS Settings
We have decided to provide users with both 400 and 450FSB starting points for quad-core processors. These settings are geared towards a performance oriented setup for 24/7 usage. Individual systems will require stability testing according to personal preferences and component selections. The settings shown are a guideline only; voltages may vary according to individual components and motherboard ability. Remember, perseverance is the key when overclocking!
2GB QX9650 BIOS settings
| Gigabyte GA-X48T-DQ6 Bios Settings @ 400FSB | |
| Robust Graphics Booster | Turbo |
| CPU Clock Ratio | 9x |
| CPU Frequency | 400FSB |
| CPU Host Clock Control | Enabled |
| CPU Host Frequency (MHz) | 400 |
| PCI Express Frequency (MHz) | 100 |
| C.I.A.2 | Disabled |
| Performance Enhanced With | Extreme |
| System Memory Multiplier | 4.00B |
| DRAM Timing Selectable | Manual |
| CAS Latency Time | 6 |
| DRAM RAS# to CAS# Delay | 6 |
| DRAM RAS# Precharge | 6 |
| Precharge delay (tRAS) | 18 |
| ACT to ACT Delay (tRRD) | 4 |
| Rank Write To READ Delay | 7 |
| Write To Precharge Delay | 10 |
| Refresh to ACT Delay | 60 |
| Read to Precharge Delay | 5 |
| Static tRead Value | 6 |
| Static tRead Phase Adjust | Auto |
| Command Rate | 1N |
| CPU/PCIEX Clock Driving | 800mV |
| CPU Clock Skew Control | Normal |
| (G)MCH Clock Skew Control | Normal |
| System Voltage Control | Manual |
| DDR3 Overvoltage Control | (+)0.55 |
| PCI-E Overvoltage Control | Normal |
| FSB Overvoltage Control | (+)0.35 |
| (G)MCH Overvoltage Control | (+)0.25V |
| Loadline Calibration | Disabled |
| CPU Voltage Control | Normal |
If stability issues are experienced with these settings or lower a VDimm is favored, CAS 7-6-6-18 - 1N timings should suffice.

this isn't a typical mobo and it's not being reviewed as such. this article is testing the limits of highest-end board with the highest-end cpus. comparing it to 965 or p35 based mobos makes no sense since a) it's twice as expensive when ram is conisdered and b) the buyer for this type of hardware wants the absolute best performance possible and not the best bang for the buck.Rob94hawk - Wednesday, January 2, 2008 - link
Been running my Corsair CDFN @ DDR3 1800/7-7-7-20 on the X38T board for a couple of days now. E6750 450x8 @ 3.6Ghz finally Orthos stable (With BIOS F2!)http://www.xtremesystems.org/forums/showthread.php...">http://www.xtremesystems.org/forums/showthread.php...
Great review though. A few BIOS tweaks in here that I did not know about that might help me on my quest for 4Ghz on air.
Was thinking about pulling the mobo heatpipes and re-seating them with some MX-2.

I have to agree, but not only that : The X38 DDR2 board from Gigabyte seems to respond in much the same way, and displays the same quirky behaviour the X48 sometimes does.I do hope things get better as time passes, as the "reboot to a messed up bios" problem is really bugging me.

My 965p-ds3 rev.2.0 does the same thing. HA!....... I'm starting to sense a pattern here.....Rob94hawk - Wednesday, January 2, 2008 - link

Hi Rob,Looks like you're running the X38T and not the X48T?

Yes I've got the X38T and it's a great mobo.
