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

[Miss666Gothic]

I assign as video memory? changes in this model

award modular bios v6.00PG please help me

[nate42nd]

@r1ccardo Cool, thanks. I will have to find that video. I know you're right depending on the chip. I have had mine over 4Ghz with cheap cooling but it runs too hot. These are great CPUs. All the best.

[nate42nd]

@r1ccardo You almost have to borrow a CPU from someone as I recall. Some computer shops will "loan" you one to flash you bios.

[konstantineb]

In practice:

Dynamic VCore (DVID) = +0.10625

Effective CPU Vcore at Load =1.3000V (now able to lower voltages "v-core" in idle mode to less than 1 )

[konstantineb]

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.

[konstantineb]

Your welcome.

Overclocking to 3.8Ghz+ should be easy on this board.

The good thing about Gigabyte boards is that the overclockability and quality of their mid and low end boards are pretty much equilvalent to those of their high end boards.

Good luck.

@konstantineb

How would you set Vcore to normal? Is that option available when you are adjusting the voltages?

Also if you have kept the Voltage at normal then how would you be able to attain an overclock in the first place, since you would need additional voltage to sustain higher clocks...?

[konstantineb]

@MrGrandDragon

Yes, set the vcore to normal and add a dynamic voltage (the option appears when u change vcore to normal mode).Once that's done, go to the power saving options and set them all to enable from auto so that the vcore and CPU clock will drop and rise depending on load.

This is only for Gigabyte motherboards.

[MrGrandDragon]

@konstantineb

Do I have to also enable C1? My computer would not boot up and my Mobo said C1 and kept rebooting...

My normal voltage is at 1.335 (in grey) so could I set the Dynamic Voltage to 0.015 to get 1.35v? I am trying to get a 4.5GHz clock so people have told me I would need 1.35v on Load line Cal lv 7...

[konstantineb]

@MrGrandDragon

Yes.What happens is that when you change vcore to normal mode the BIOS halts all the power saving options.You need to force them by setting them to enabled.

C1 will allow you processor to enter Idle mode.This is when the CPU is not doing anything really and just handling a hardware interrupt.So the clock speed and vcore are reduced to very low values which saves power and reduces heat.

flash ur bios to the latest firmware, and then try enabling em.

[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. :)

[konstantineb]

@MrGrandDragon

what mobo and cpu you got there??

[MrGrandDragon]

@konstantineb

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

[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.

[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.

[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.

[MrGrandDragon]

@konstantineb

What about the CPU PLL OV option? 

[konstantineb]

@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]

@MrGrandDragon

What's the CPU clock speed ur at?

[MrGrandDragon]

@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...

[konstantineb]

@MrGrandDragon

set Dvcore to 0.1-0.13 V and u can get your CPU to 4 - 4.1GHZ.Disable Turbo and enable all the power saving options.You need to do all this after flashing ur BIOS.

Over 4.2GHz wont add much performance and it will require to much power (vcore), so don't go there.

[nate42nd]

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

[MrRadjevic]

Well, what you want to do is ENABLE it and then lower the vCore as much as you can.

[MrRadjevic]

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

[nate42nd]

Thanks for the information.

Nice video! Good luck getting the answers U need! Hopefully 1 of our fellow youtubers will be able to tell U something! 5/5
