How is the GA-P67A-UD3 LGA 1155 P67 - Page 2

Sounds good, thanks for the update.

LLC is the biggest issue so far. There are two settings "off" and "on". "On" lowers the voltage drop somewhat, but it's still significant.

The other issue is that BIOS has a tendency to "detect" checksum errors and revert to the default F3 firmware if you try to go too aggressive on overclocking. It has dual BIOS, one active and one backup. When you load the new firmware, it goes into the active area, and the backup area has the original F3. I haven't found a way to update the backup area yet.

hold down atl+f12 on bootup screen it will flash the backup BIOS to new BIOS that you have in the first BIOS. THe checksum error is a problem obn all P67A gigabyte boards, its because the threshold is set too low for BIOS corruption, so even if its not corrupt it back flashes, its not htat BIG of a deal but a pain i know, so try the ATL+f12.

I just signed up for this website after checking up on Sins guide many many times smile.gif

I currently am running an I-2500k on the UD3. It has SERIOUS vdroop issues. I'm happy to hear they're being fixed but in the meanwhile you might want a board not facing them.

I am currently able to run at 1.375V at 4.5ghz. LLC is enabled & PLL overclock is disabled.

Easytune 6 reports as Voltage of 1.392 IDLE, during PRIME 95 that drops to 1.33V. This leaves me very hopeful that the new bios will allow me to run 4.5ghz at 1.33V but worries me that my voltage is normally around 1.4v and drops by 0.67!!!

In other words just avoid the board lol. Oh yah and all of a sudden after installing a new heatsink the board will only recognize up to two sticks of DDR3 effectively forcing me from 8gb - > 4gb. Still haven't figured that out either.

i reported the issue again, just to make sure, Now you can enable cpu pll overvoltage as it will help you get higher clocks and doesn't hurt anything, might even help you lower your vcore.

I did a bunch of tests with pll overvoltage on and off. Overvoltage does NOT have any effect on stable vcore. All it does, is allow you to boot past the 'ceiling' (in my case, 4.4). Below the 'ceiling', the critical vcore is the same within 0.01 v, with and without overvoltage.

your ceiling can't be 4.4ghz that is wayy too low. What are all of your settings?

I got a response, basically its Chinese new year, so just hold on.

Everything is default except Vtt=1.100, LLC=on. I've just double checked, it works fine at 4.6 @ 1.42 if PLL overvoltage is on (I'm pretty sure that it'll boot and work well even at 4.6 @ 1.38), won't even get out of BIOS at 4.6 @ 1.42 if PLL overvoltage is off.
