I hope it works,otherwise its looking more and more like a hardware issueI really want my 990FXA-UD3 or UD7,will need to paint the gold bits white though to match the rest of my build,not gonna happen until problems are fixed though.I dont want to have to buy Asus or another brand as they all look horrible.If Gigabyte cant fix this then i might have to get the ECS Black.

Hey, Add me to the list. . . . Although my BRAND new 990FXA-UD5 is all fail with the temp sensor ATM. . . Works in bios so its a software issue, just can't get any program other then Easytune6 to read temp *(HWmonitor/AOD/OCCT/Core Temp)*

!!EDIT!!
Yes, Tried reinstalling them,
Yes ALL the programs. .
YES I did uninstall them all before re installing.
I even tried a System restore to 24 Hours ago *(Although its now more like 36 hours ago as i did that 12 hours ago)*

thats gamble as ECS has been peddling garbage for years. you can also go Intel believe it or not being an AMD fan boy Intel keeps looking better and better recently. Didn't here about vdroop on the ud5 and ud7 intel boards.

Guys, you've seen that overclocker Chew or whatever overclock a BD on the UD7, pretty high PHII overclocks on the UD7, I think the vDroop issue is fine. If you lose more than .1GHZ from this board upgrading from an 890FX, than it starts to become a problem.

Working on 4.3GHz.
Load temps between 39-42.
post #527 of 12377
Nice load temps! What are your ambients? What did you have to set the vcore to in BIOS to get 4.3 stable? Any active cooling on the vrm area?
With my loop in 84*F temps, my cpu will load around 52C

I also have submitted a ticket to gigabyte support

I'm not a fanboy,lol,just a cheapskate.I may well go Intel yet,but never Sandy Bridge-'man can not live by multiplier overclocking alone'

Seriously though,i like the tweaking,and after my current set-up i want to finally have some fun
post #529 of 12377
Hey for those of you who want to get rid of the vdroop i have a solution. I know some of you don't wanna wait for an official fix, whatever your reason may be, but Intersil PWMs are easy to mod. I have made mods for the UD7, of course only the experienced OCers should even attempt it, but its its actually pretty simple, easier than most mods.

Before I begin let me explain how its works, we are replacing a resistor that is connected to pin4(droopcontrol for NB and Core). its a simple mod, you replace the resistor already in place, and replace it with exactly 100K ohm of resistance, either through a fixed resistor, or a pot as shown in the picture.

If you do this mod, you cannot go back to having droop.

Honestly, the vdroop isn't going to hurt your OC, just set a higher voltage so that your load voltage is what you had on previous boards, or what it needs to be to maintain stability. A bit higher voltage at idle isn't going to hurt anything nor produce much heat, load voltage is really all that matters, of course please do respect voltage limits.

I take ZERO(0)(NO) responsibility for what you guys do, if you can't handle a soldering iron don't attempt. If you have doubts just set the voltage higher instead of doing this.

I am told that this vdroop is part of AM3+ official design guides, so any type of LLC or this mod is not how the CPU wants to be powered, but heck we are OCers, so enjoy.

THE MOD SPOT FOR UD7 ARE NOT THE SAME as the UD5!!!! PLEASE DO NOT MIX UP!



990FXA-UD7:


PS: the UD5 has a very similar vdroop mod possible too, but I need an upclose picture of its PWM, just like the one above.

well this UD3 seems to be a great board, I haven't noticed any VRM problems, but my 790FX-UD5P had a more solid vcore. UD3 do overvolt by 0,03V the CPU when loaded.


My 790FX Overvolts vdimm by 0,06V and it only had 0,05V VDRAM increments. The readed value was wrong also, and it shows the same that was set in bios and that was 0,06v higher when measured w/ DMM.

900FXA-UD3 has 0,005 vdimm increments that's very nice, and readed, real, set voltage are very precise within 0,01v difference for DMM.

It seems that the new driver mosfets sux anyway, glad that I ordered the UD3.

XA doesn't have anyproblem also. (no drive mosfets, drmos?)
