Well with a C3 2800Mhz might need about 1.325-1.350v for stability. and for 3ghz it may very well need closer to 1.40-1.425v. Have you tried setting the Ram Strap to 1333Mhz (ratio 1:3.66), Setting the CPU to Stock Frequency and Seeing just how high the CPU-NB Will go on 1.25v? I only suggest 1.25V as it's within the Stock range of 1.15 to 1.30v. Either way, Setting the CPU-NB Volts manually to whatever votlage and seeing how far stability can be pushed, at that volt, to get a baseline of how much she'll end up needing is always a good idea.

REALLY? That's Crazy! So are you referring to people using the VDD voltages INSTEAD OF the voltages, or in conjuction with?

I saw and I discussed this same thing even in the 890FXA thread.

I've read more than two or three cases that the board was burned by people who, for disinformation, raised the VDD voltages instead of the effective voltages.

Ah, what dipsticks! lol- No really though.... Thats's to bad that they were misinformed!?

SO. I have a Question for everyone.

Based off of the fact that this board (Rev. 1.0 especially) can have some pretty substantial VDroop, has anyone noticed whether or not using the VDD Voltages set to the Stock Voltages for the CPU has helped with the VDroop of this board during full load?

I set my vCore(CPU Voltage, not VDD) in BIOS to 1.48v. In CPU-Z at idle the Volts read 1.472v and at full load it drops to 1.456v. That's .024 volts of Vdroop.....

Anyone have any expereince with this?

The thing I noticed about the Vdroop is that it is not as bad as read by SW, and that VDD will not help.

If you actually read the cpu-v from the v-points on the board you will notice much less droop and that you might actually be running a little lower then you thought.

i set the cpu vdd to 1.400 and cpu to 1.460 and cpu-z show 1.44-1.45. so it doesn't seem to make any diff. i've been using these settings for 6 months and haven't had a problem. no cooked mobo

My 965C3 behaved like yours.

But with my 1090T configured to 1.48V in the bios, CPUZ shows 1.496V at idle and 1.488V at full load.

I noticed that Everest (Compared to CPU-Z), which is all that I really use for monitoring, will round the voltage up. So if CPU-Z reads 1.472v, Everest will read 1.48v.... I tried using the VDD's just for this purpose but had no results other than the ability to finely adjust the Core Voltages by .025v....

That's good! No one likes the taste of "Fried PCB and Chips" for dinner!

So during full load does your vCore droop about .024 of a volt compared to what you set the CPU Voltage in the BIOS?

Is this at 4Ghz? And BTW, what BIOS are you using for that? Have you noticed that you have the opposite situation with a different BIOS or does the vCore always run higher than the BIOS vCore setting?

Do you have a revision 1.0 or 1.1 GD70?

The cooked mobos that I saw was about 1,45~1,50V CPU VDD. But this is only a speculation that seemed to have some sense.

4.1GHz. 1.13 bios and 1.1 revision printed at board.

I already installed 1090T with 1.13 bios. But with 965C3 and the same bios I had the opposite situation (like yours). BTW is a cpu feature.

Really thats funny I have been using both for about a year now with my 1090t I set the cpu vdd to 1.400 and cpu to 1.480 for 4ghz, and in CpuZ it shows 1.480v. Under load it hardly ever moves to, but it has droped to 1.476v befor. With my 965 that I really hated, I could not even get 4ghz with 1.600v, but now that I have my 1090t I have been playing around with my AMD build more.

This is because by default Everest is set to read only two decimal places. You can chage the setting to 3 decimal places and it will read exactly like CPU-Z
