Hi Valachia,

looks like we're both 1st time posters. Anyway, to answer your question...

I have the X79-UD5, BIOS F12 and i7-3820. I pulled out my multimeter and measured the VCore through the hole at the bottom of my case and found that my voltage was going to about 0.995v for a very brief moment and then jumped to 1.375 (needed for 36x125, 4.5 GHz). That period with 1V might only be a misreading since the measure interval could have been to short to get to the correct value before the next interval.

Either you are having the same measuring problem but mistaken as too low or your board does something substancially different, which is unlikely within the same series of boards. To activate the strap I had to set the CPU core mulitplier to 12x and RAM multiplier to 8x (minimal values) to make it start at BCLK100 first before applying the rest of the settings... Thanks to san0822 at xtremesystems tho for that hint. ^.^

Thanks very much for your reply,

I can get the board to boot the way you described with low multipliers and 1.25x strap. But the problem is that after doing this, if I then apply higher multipliers to achieve a reasonable overclock, when I shut the pc down it won't boot again!
I have to go through the whole process again, every time I power on because I cannot get the power-on vcore to budge past 1.00v with 1.25x strap. I have tried slowly increasing CPU multi with all power saving settings off, then rebooting. This *should* force the CPU to readjust its automatic SVID settings to allow for the higher CPU speed, and this method works fine for me with the 1.00x strap but not with the 1.25x.

If you run Easytune 6, go to the Tuner tab and click 'Advance' (top right) then go to Voltage I tab and you can see the first setting is CPU Vcore. It shows both the power-on vcore and the target vcore that your board is currently using.
When you are running the 1.25x strap what does it say for power-on vcore?

I'm really curious because I agree that it is unlikely that these Gigabyte x79 boards differ very much in this regard, but when I use the 1.25x strap Easytune always shows power-on vcore as 1.00v regardless of how high the overclock is or how many times I have rebooted.

I have already contacted Gigabyte support on this.

I have tried F5, F10, F11a with my board and the only usb ports that work to enter bios with my Logitech G15 keyboard and MX518 Mouse are the 2 usb ports below the ethernet port. Also bios F5, and F10 allow me to select 2200-2600 memory speeds for my Samsung MV-3V4G3D/US ram but the settings will apply but after startup ram is still runing at 2133. Bios F11a will apply the settings but will never boot up, the only thing I get are what sounds like 10 or so fast beeps no matter what voltages I throw at it.

I just tried to install ET6 on my secondary Win7...guess what? As soon as it tries to start after booting, it crashes the system. OS freezes, not even the reset button works.

This just confirms why I don't like OC software. It takes a running system while it supposedly stabilizes overclocks. This just cannot work when you really need it, besides, I have never seen such software offering functions that go beyond the BIOS.

I'd rather regard this wording of "Power-on" values to be DEFAULTS, like the left column next to the settings in the BIOS. Those values were pretty off to begin with...

What's more even if the board starts with 1.00 VCroe, it might be while the CPU is still on default clocks.

Maybe a filled-out BIOS template helps here of what you are setting your voltages/clocks/etc to...

Edit:

An older version of ET6 works here now. Power on Vcore is also 1.00V here. Seriously that sounds like default to me...Not even, default should be 1.18V for the core.

Here's the most crucial values for stability overall:

VCore: 1.375V (36x125, may differ some!!)
Vtt: 1.05v (QPI clock is 5 GT/s, so why increase above default? 1.10 and more cnan lead to unexplainable reboots)
CPU PLL: 1.81 V
IMC: 1.14V (Keep within 0.3V of VCore to remain stable.)
PCH Core volt: 1.2V (Less than 1.18 causes various problems. GPU driver crashes, sporadically not detected SATA devices)

Hope this helps

Hello all, I have a GA-P35C-DS3R motherboard and I was wondering if the bios version below "F13d" would support 3TB SATA HDD?



"GA-P35

GA-P35T-DQ6 - F8a
GA-P35T-DS4 - F7
GA-P35T-DS3P - F7
GA-P35C-DS3R - F13d "


thanks
Chris

Could someone re-upload the GA-EP45-DS3R BIOS image with the v1.20 AHCI ROM? It solved an issue with very slow AHCI detection on boot which I'm currently stuck with.

Someone already posted the file a couple of years ago in this thread, but the link is dead now. The filename was EP45DS3Rm.11c.

Edit
For anyone else looking for this, I found it here.

Thanks again for your reply,

Interestingly if you try the 1.00x strap you will see that 1.00v power-on vcore change to around 1.24v.
So the issue I'm trying to resolve is why does it drop to 1.00v when using the 1.25 strap? Seems like a bug to me, and I can confirm that
the Asus Rampage IV Extreme and the MSI X79A-GD65 don't do this. In fact the Rampage lets you set your own power-on vcore :-)

Thanks for posting those settings too, I will try them later. I really would like to be able to use SVID (set CPU vcore to 'normal' in BIOS)
instead of setting 1.275v vcore though. I hope gigabyte can sort that out.

I have updated to bios F9 for the Z77x-UD3H - when I install windows the USB ports stop working and I cannot install windows 7 (I have tried all ports its the same) - but works fine in Windows 7 and BIOS.

Is 11a worth upgrading to? Do you think this may resolve the problem or should I revert back to F5 (this was original bios and was fine for usb)
