Gigabyte P55-UD4P New BIOS (F4) and some questions

Looking around at the new BIOS. (F4) for the Gigabyte P55-UD4P. Wondering what load line calibration "Auto" setting does and what "Dynamic VCore" (DVID) setting is. Also doing a small overclock to 3.36Ghz. If you have information on the new features please let me know.

Load line calibration is to prevent V-core drop under heavy loads, and even push the v-core a little bit if more power is needed.If LLC. acts aggressively, disable it.

Dynamic Vcore allows reduction of VCore between idle and overclocked modes. To activate it you need to set V-core to normal.

Dynamic V-core=the additional extra voltage needed tp reach the desired voltage..

Thanks for the info konstantineb.

Now F5 and F6 are out. I need to get it flashed. Thanks again.

It looks like F5 is now the latest BIOS for this board now. 11/29/09

Loadline is designed to limit vdroop to a point, but it can also be dangerous especially when your very close to ur max vcore. Loadline holds the same voltage from idle to load, but the only drawback is the voltage can spike due to overhead and can cause dangerous voltages to be shot to ur vcore

Thanks for the information.

@MrGrandDragon

disable it.And for SB processors, i don't think u need to mess with the PLL voltage.Just keep the pll voltage on auto.A v core of 1.24V-1.27V should be where ur processor at 4.5GHz can sit.

@konstantineb

What about the CPU PLL OV option?

[konstantineb]

@MrGrandDragon

Never use XMP, it screws things up.Overclock ur ram manually by increasing the DRAM multiplier and also try to set ur CPU multi on 45/46, Dvcore to 0.1V and disable turbo and see what happens.

See if using normal vcore mode disables EIST and all the other fixed C power states.

Also, I believe the controllers on modern SSDs use AHCI by default so forcing it through the BIOS or the OS is not necessary.

Disable LLC if its causing problems for now.

@konstantineb

I have gone back to default 3.3, so my BIOS as it stands is normal. I only changed the SATA to AHCI for optimal SSD performance. Also I am running 64 bit so I have change that also. Oh & I disabled ESATA/ GSATA function since I wont be using either of those ports on my Motherboard any time soon.

So @ the moment I have no LLC enabled and everything is on auto...

[MrGrandDragon]

@konstantineb

Aah so should I keep the CPU at default clocks? Or could I simply put the multi at x40 on Turbo (all cores) without any voltage increments? My RAM is set via XMP profile 1 on Quick and Turbo (Default settings) 1600 9-9-9-24 DDR3...

I was told to enable CPU LL? Should I disable that? I will try enabling both and see what happens.

@MrGrandDragon

What's the CPU clock speed ur at?

[konstantineb]

@MrGrandDragon

U should've told me that earlier.Why do u need to overclock the 2500K? There's no game that can be bottlenecked by a stock 2500K that goes to 3.7GHz on Turbo.

Anyhow, ur saying enabling C1 makes ur pc cycle reboot right? Make sure CPU EIST is enabled and also make sure ur RAM timings and voltage are not excessive.

Also it could be ur VTT, PLL or PCH voltages that are too low.Cuz when u increase the Bse clock ur overclocking all those controllers.

@konstantineb

I have a Intel i5 2500k, z68x-ud7 :)

[konstantineb]

@MrGrandDragon

what mobo and cpu you got there??

[MrGrandDragon]

@konstantineb

I have F9 installed on my BIOS using @BIOS software from the Gigabyte website...

The thing is I want to have a stable 24/7 4.2 clock...

If you could help me with that then it would be awesome. :)
