voltage! what the heck! - Page 2

post #11 of 20
Its not that cpuz is 'bunk'

I use three programs for voltage reading. CPU-Z, Asus Probe & SpeedFan and they all show me the exact same voltage of 1.38 whn my bios is set to 1.45

Usually the fact that the voltage is lower is because of the electrical load on the system, and sometimes due to a cheap PSU or Mainboard power regulators/dividers.

To many people are banking on what they set in the bios. This is not nor will be your real time voltage, its just an adjustment, go by what CPUZ says or better yet what the bios monitor says. Just because you set the vcore to 1.45 in the tweak area does not mean that it will be 1.45 theres alot of variables between what you set and what you actualy get, for example, before i modded my board, I would have it set at 1.5 in the bios, but would only get 1.4 in windows and under the bios monitor do to the droop of the board. Now that the board has been droop modded, if I was to set the vcore at 1.5 like before my actual vcore would be around 1.64 instead of 1.4. So currently @ 4.5ghz my vcore is set at 1.26 in the bios, but the bios monitor, CPUZ PC Probe and every other program reports it as 1.37, so to make a long storry short stop looking at the bios setting and go by what CPUZ and bios monitor say, they are pretty accurate in most case's.

Exactly.

Why would three different programs report the sam voltage but Bios display a different, higher voltage.

A lot of guys over on XS show there voltage as e.g 1.400v After Droop, which would suggest they believe the windows readings to be the true voltage

The mistake I see alot is people looking at what they set in the bios and not the actual bios reading(under hardware monitor). To many people think CPUZ is wrong which its not, its alot more accurate then they think.

edit btw rep just for getting it.

3 programs could give you the same results because the sensor is the same, and they all interpret it the same way. It doesn't mean they are correct because all of them give the same results.

For an instance, every program I test my +5v with says that I have 6.85V on it. Crazy huh? This means a bad sensor and there's nothing any software can do about it. with a multimeter I'm solid 5.11V by the way.

About the vdroop - It's usually because of the board. It's not really a bug, I believe most manufactors put it in intentionally. There is also a specification from Intel requiring some sort of vdroop.

I appreciate your explanation TankGuy, yet I don't just want to go randomally testing chips in my PC. About finding the information online - I'm afraid my board is very rare among overclockers. Couldn't find information regarding testing the vcore with a DMM in it. Nor could I find any mods for it. Anyway, REP for you for a great explanation

I know this might be too much to ask from you guys, but does anyone have the knowledge of finding mods in motherboards? I wish to find a vdroop mod for my motherboard(like I said - google yields nothing), because I believe the serious vdroop is what's preventing me from reaching 200+ FSB stable. I can supply all the pictures\\information you need, and I have a multimeter and whatever tools necessary. I just lack the knowledge of finding the 'spot' that controls vdroop myself.

Check in your bios under Power Management.

I set my Vcore to 1.45 and reboot. Enter bios again and the 1.45v is still the same but on the next page under power management the vcore is displayed as 1.38v, the exact same temp as the 3 windows programs display

I know what your saying about an incorrect reading from the sensor, but how can you select a voltage in bios then got to the next page and have it display a different lower voltage. I always go by the lower reading now, thats the true voltage in my opinion and a lot of people are of the same thinking.

Head over to Xtreme Systems for the Droop Mod, I saw it in there a few days back. Just type droop mod in the search bar

The reason why you get a lower reading is as I have explained above - it's the Vdroop of the motherboard. Every motherboard has it. Asus are well known for it. My specific board is a Gigabyte one, yet it has the most severe Vdroop I have ever seen!

I have been to both Xtremesystems and VR-zone asking for help. so far I haven't received any answers there. I'm pretty sure my threads are 'dead' ones so I won't be receiving any help either.
There's no past information regarding my board either.

That's why I'm asked for some help in here. Maybe someone is willing to assist me in the process of finding a vmod to my board. I will hold no one responsible for my own actions. I just need some help.

All I could find on vdroop for gigabyte was this picture. Only thing is its from the DS-3, it might help if you have a similiar board layout??

Thanks. I've found this too. Unfortunately it's for the 965p-ds3 right? It is EXTREMELY similar to my board (the layout that is), but it seems that it's still a bit different.

I'm afraid doing a mod on a not exactly the same board might have terrible results.
Is there no one that can jump in this thread and assist me? Like I said, The responsibility is all mine
