Is there anyway to counteract the massive vdroop I am experiencing? My cpu voltage is set to 1.525, yet when running stress tests my cpu voltage is dipping down to around 1.44 to 1.45.

I have raised the CPU VDDA to 2.8 ( goes from 2.5 to 2.8 in bios) because I have heard that can help with the vdroop, yet that has changed nothing from what I have seen.

If you have a cheap psu like u say you do, it could cause it also. There's always a little Vdroop but yeah urs is quite high. What programs have tried looking at the voltages.

 

[tyfavre04]

I have used both CPUz and HWmonitor. Both indicate the same voltage. I have heard that the PSU could be the issue, but I have also seen other individuals with the same mobo and a better PSU (Coolermaster Silent Pro 600W) and they were experiencing the same problem.

LLC <-- Enable in your bios.

I'm not sure but i think only intel mobo's have that.

Load Line Calibration... You should have it.

 

[Meta-Prometheus]

Load Line Calibration is Intel only I believe...

 

[arbalest]

I swear there is a LLC Equivalent on AMD boards... It's been SO long since I've used AMD though.

If there isn't LLC of some sorts, I apologize.

 

[tyfavre04]

There is a feature called Advance Clock Calibration, but I have hiked it on up to 8% on all cores and the vdroop has still stayed the same.

 

[tyfavre04]

I tried another PSU that was a bit more in voltage, but nothing changed. It was an Antec that was by no means anything to talk about, but I would at least think I would see a minor change for the better.

I have the LLC feature on one of my AMD boards an this board also gets massive vdroop but I have no idea what to set it to.

pencil mod, do it

Question: could the fact that my PSU, which is 380 watts, is so low in wattage and the 12v rail only has 18 amps be causing the extreme vdroop I am experiencing?

To note: I am experiencing a consistent .6 or so vdroop on full load and about a .15 to .2 on idle.

Wait... You're using a 380w Antec to power your setup + an 8800?!

Yes, that could most definitely be your issue.

Not much power there in the psu, plus low amps on 12v rail.

Yeah, the only thing is I don't want to go lay down 80 bucks on a PSU and then still get the massive vdroop that I am experiencing. I wish I had a nice one to test at least. I know arbalest is saying that is definitely the PSU and a new one would fix it, but can anyone verify with having experienced this scenario before?

 

[mr-Charles]

let's see:

U R usin' a 380W. PSU

4 =

1= using an 8800 series video card

. . . . . tsk, tsk, tsk

2= using a "AMD Phenom II 955 C2" for this setup

..... tsk tsk, tsk

3= and, trying to OvrClck this to like 3.8 to 4.0???

.....tsk, tsk, tsk

4= also, you have a case with BAD Air Flow

. . . . . tsk, tsk, tsk

5= don't suppose U got a pic to show the "Spaghetti Bowl
of Wire's" within, do ya??

WELP, LOOK's to me like ya better look/go shop for a
NEW'r PSU, especially if you got ANY idea's of
going SLi / Crossfire for later . . . sorry to say
that your 380W PSU has seen it's day's worth
of use, and it's time for it to step down for an
"UpGrade'd, NEWer more Efficient one" to be
taking over the duties within your system . . .

.....{ my 2

for ya on this, tyfavre04

It's possible but most likely upgrading your ps isn't going to help.

Some boards just have this and you have to deal with it.

I'm unfamiliar with your bios so I don't know about llc.Not all boards have it.

rep to you my friend runnin' that rig on 380 watts.Just proves how many people over do it.

I have also a vdroop on load 1.475 on idle like should be and 1.43-44 in prime95.
