ASUS Maximus Formula SE

[-=j0nnyr0773n=-]

Anyone come across a usbehci.sys BSOD? been trying to figure out exactly what causes this as it is always usbehci.sys that crashes, and it usually happens when my machine is in the process of restarting (still in Windows) or when it first logs into Vista.
The reason for crash is DRIVER_IRQL_NOT_LESS_OR_EQUAL
Is this possibly related to the BIOS EHCI Hand-off feature? or a hardware conflict of some kind?

Try running a chkdsk /r on the drive, that has fixed that error before for me.

Oh and here's the newest stable settings with the lowest voltages I can achieve so far. Still trying to lower them.

CPU Ratio Control Manual
Ratio CMOS setting 8
FSB Frequency 450
FSB Strap to NB Auto
PCIE Freq 100

DRAM Freq DDR2-1128mhz
DRAM Command Rate 2T
DRAM Timing Control Manual
cas 5
ras to cas 5
ras precharge 5
ras active time 15

Everything else AUTO

-----------------------------------

Voltages


CPU Voltage 1.4875 (1.464 droop)
CPU PLL Voltage 1.5
NB Voltage 1.61 (overvolting to 1.65)
DRAM Voltage 1.98 (overvolting to 2.1)
FSB Term Volt 1.4 (overvolting to 1.472)
SB volt 1.050 (overvolting to 1.09)
Loadline Calib Enabled
CPU GTL Ref auto
NB GTL Ref auto
DDR2 channel A auto
DDR2 channel b auto
DDR2 Controller auto
SB 1.5v 1.5

Both spread spectrums disabled.

VID: 1.3000v

These temps are under full Prime95 load while I post this. Also, I find no difference in performance / benchmarks when changing any of the GTL References, so I am leaving them on auto, if anyone has opposing information, please share

When you power a Maximus on for the first time, what will your RAM voltage be set to. I have 1.8v RAM and don't want to fry it on initial power up...

Once I get control of the bios, I should probably set it to 1.7v with the ram over-volt issue?

Thanks

Thats exactly what you'll have to set it at.

It defaults to 1.8V. I was having issues with my 2.2V RAM not POSTing, so I had to buy some cheap stuff to POST.

Thanks for the reply's!!

I kept seeing most everybody's ram voltage set higher than 1.8v, I just figured the default was higher....

Thanks for the info.

The stock BIOS wouldn't be anywhere near 79c at 3.6GHz, the temp bug is very annoying.

so the temp is wrong?

maybe i should go back to 0505 bios? or try the new 07 bios?

I'd personally recommend trying 0505 out, I've been trying them all out but have decided to settle with 0701 purely because it helped with tighter memory latencies.

0701 helped me with the x8 multiplier. I could not get 450x8 to work, before 0701, but after I flashed I can.

I had to raise my northbridge voltage farther than expected in order to get a stable system above 400 fsb.
