High Required Chipset voltage(1.8v)

Recommended Posts

So I have been playing around with my 3500+ for awhlie now and haven't been

able to do anything spectacular with it yet. However one thing that I was able to

find out is that unless my chipset is at 1.8v :eek: the system is very unstable.

 

It runs fine at 200x11 at 1.7v but any type of overclock requires the chipset at

1.8v.

 

Is it possible there is something funny with my board. It seems like most people

aren't running that high? I know my memory will do [email protected] timings so

that's not the problem.

 

I will be swapping cpu's with a friend this weekend to see if the CPU can do more

on his system than on mine. It seems like I have had nothing but stability

problems ever since this thing got put together :sad:

 

Hopefully you guys can shed some light on this. I am seriously thinking about

RMA'ing this board.

 

Thanks in advance!

Measure the voltage with a multimeter. It is possible that the voltage regulation is off and you can are actually at 1.6 volts.

Thanks for the input. Where on the board should I measure the chipset voltage?

Is there a webpage or a picture showing the measuring points you could point me

to? I guess if the voltages are off I would have to RMA it :( That makes me

wonder if my CPU voltages are correct since at almost 1.7v in the bios my chip

doesn't get over 44C at full load(which I have been told is too low for air cooling)

 

Thanks for the tip! :D

So what was the out come of this ?

I will be trying it out this weekend so I will report back what i find out.(both

multimeter readings and different CPU performance results)

 

Thanks!

I am trying to figure that out myself. Supposedly you can measure it somewhere on the back of the board but I didn't have time sort this out.

 

Seems people don't do that often...

Ok I was pointed to a thread that showed where to measure voltages here:

 

http://xtremesystems.org/forums/showthread...7631#post777631

 

It was a little tricky but I put electrical tape on everything around it just to make sure.

 

My readings were 1.78V for the chipset, 2.880v for my ram and 1.448v for the cpu.

 

With these readings it's apparent that my chipset is getting 1.8v so there must be

something going on with it since it's not stable under 1.8v. I have also been

testing my cpu and it seems that anything above 223x11 will cause my system to

freeze when testing instead or erroring out. I was able to fix this when I hit

220x11 by going from 1.7->1.8v but now I don't have any other voltage options.

 

It has also been very picky lately where sometimes it will pass OCCT and SuperPi

just fine and sometime is will error out or freeze within 5 min of starting even for

stable speeds.

 

So what do you guys think? Is this just a poor performing board? Should I RMA it

and try another board? I really like the options that this board has to offer and it

obviously has a lot of potential but mine just doesn't seem to do as well as

everyone else's :confused:

 

Thanks in advance!

From the dead. I've been looking to do this and today I got around to it. So in BIOS, I have the vcore set to 1.375 x 113%= 1.55, all software reads it as 1.48-1.5, my fluke series 77 reads it at 1.55, great. My ram was set to 2.8v and the fluke read it as 2.9v. Set it to 2.7v +.3 and the fluke reads it at 2.8v exactly. Once again the software lets me down, I wonder how far off the temps are.

The dram voltage on mine was always high by .07 I think they are pretty much all that way just like the smartguardian always reads .03 less than the bios. I don't think it's an issue you should just be aware of it. Not sure about the chipset voltage thing. I never messed with mine. It's pretty well known that almost all boards don't read the correct voltage or temps. A fluke is a high precisision and costly instrument. Mobos with super precise voltage reading and measuring chips would cost much more.

You mean 'Set it to 2.7v + 0.03' right? :D
