Hello all, especially the Abit BIOS programmers,
Is this forum still alive? I've sent 5 mails using the Technical Form on
abit.com.tw and I've sent mails to firstname.lastname@example.org and so on, but
I didn't get any reply back yet. Now I recently found out that Abit has
stopped producing motherboards and that this forum exists in return!
Very nice !
So.. What's the question? I recently downloaded the last bèta bios
"m704b" from the "BIOS updates for Intel E0 stepping"-thread. And
that BIOS works very nice for my Xeon Quadcore X3370 (aka Q9650 E0).
Thank you very much already, even Virtualisation Technology and the
CPU temperature reading is working correctly now!
Ok the question, sorry... Would it be possible to add one more 'feature' to that
"m704b" BIOS for the Abit IX38 QuadGT motherboard? A feature that would
greatly reduce the huge voltagedrops (referred as Vdroop from now)?
My idea is to monitor the ACTUAL CPU Core Voltage (from the uGuru Voltage
Monitoring menu) and the SET CPU Core Voltage (from the main uGuru menu).
Now knowing this two variables (i suppose you can declare variables in a BIOS ?)
The Vdroop can be solved if the CPU Core Offset voltage would be (dynamically) set to:
SET CPU Core Voltage - ACTUAL CPU Core Voltage = CPU Core Offset Voltage, which
can be negative if the ACTUAL CPU Core Voltage > SET CPU Core Voltage.
For example if a voltage of 1,40V is set in the BIOS and uGuru reads a voltage from only
1,33V (what is happening in my case when the CPU is under load), the CPU Core Offset
Voltage would automatically increase/decrease until SET = ACTUAL? Is this a possible
Now I'm running my Xeon at 4x 4GHz with a Core Voltage set to 1,425. In idle the CPU
gets an actual voltage of 1,40-1,44V, which is not needed at all, but only 1,34-1,36V at
full load, and that's not enough to be 100% stable ! Setting a voltage higher than
1,425V would become dangerous as this CPU's max Vcore = 1,45V. So actually I've still
some headroom left if it wasn't for the huge Vdroops :-(
Can the Abit programmers please help me?
