too much on the 12v line?

[comradeboris]

hey all,
i have a 520w ttgi psu that i normally run on a dual amd setup that i have, and as such i have bumped the 12v output on it tremendouly. i have now hooked that psu up to my 8k3a and 1600+ combo do do some benching, and i am getting like 12.46v on the 12v line. is that too much for the voltage regulators????? someone please let me know as i do not want to burn up another mobo :) !!

You're still well within 5% tolerance. I woudn't sweat it too much. I think I've seen plenty of guys running things with their 12v that high also. Maybe some of them can speak up.

btw...welcome to Xtreme! :toast:

[comradeboris]

thanks a lot for the reply....i was just worried because of the issues that ive heard of the tyan dual mobos and melting atxpower connectors.....good to know though!

my 12v is at around 12.60v this is measured off of the molex connectors with a digital multimeter at full CPU load...

my 5v is at 5.12v

whats the 3.3v line good for? mines at only 2.8! :eek:
isnt it the bios battery?

edit: well thats what cpucool says reading the winbond monitoring on my 8rda+

[muzz]

Saaya the 8RDA/+ boards measure the VDimm voltage.

Yea i adjusted my pot on my TTGI 520ss and im getting 5.16 on the 5v line and 12.36 on the 12v line. I was frightened when i saw those voltages. I might have turned the knob too much!

But will these voltages screw up the psu over time or its perfectly normal to have it this high.

P.S. Devils Win again!!

12.5V on the 12V rail is no danger.. I have runned over 13V on the 12V rail for months, the 8K3A draws the most power from the 5V rail.
I for example burnt my 5V cabels, atxconnector and some components on the board, just 3 days ago. I did run 2.05V for months, worked pretty fine until this happend, but i knew that it would happen becuse i noticed that the 5V cabels was going bad of the current, i did have 0.3V voltage drop over the atxcables compared to the molexconnectors. I should have change the stuff earlier but i didn't... But it works fine now after desoldering and soldering on a new atx connector and some more stuff =)
I even should be able to use the psu that this happend with(Cheiftec 340W) If i change all the atx wires and that.

Anyhow 13V 12v raild didn't burn anything up, but bad 5v cabels did.

12.54 Here :)
For me when I had it 12.70+ I had instability, with HDD and other stuff.. Now I can run high FSB and what not..
Just my .02 c

Can someone be kind enough to point me to the direction as to whereas I would find information to modding my PS to get better voltages? My 12V only runs @ 11.95-12.05 :( and my 5V only runs @ 4.95 :(

[theonetheycall]

First you can cheack if your PSU has Pots..

Can you elaborate on how to check if my PSU has pots please :P Sorry I'm a bit new to VModding, I've only been a diehard overclocker uptill now :D

Here's the thing.... software and even the BIOS readings for the voltage are way off..

for example on my system it tells me my 5v line is at 4.84-4.87v under load and for the 12v it tells me around 12.28-12.34v....

Now when i check the molex connectors with my multimeter it gives 5.12-5.13v for the 5v and 12.64-12.65v for the 12v... So only way to know for sure if your rails are ok is to get a multimeter and check for yourself.. ;)

Do not measure on the molex, on the atx-connector and on the mosfets the voltage is probley lower. So i would measure at the board and the atx as well just to be sure whats least inaccurate, but its right that the boards dosn't measure so good. But there's filters the voltage go through on the motherboard as well, when i did measure the 8RDA+ i did have i got pretty near bios readings on the mosfets, just a little higher.

I knew about the mosfets but I'm paranoid to short something out... Also how exactly would you check out the voltages on the ATX connector if the PSU is connected to the motherboard and doing something CPU intensive.. :smileysex

[comradeboris]

to see if there are pots open the psu up...ad if there are any you will see like yellow small knobs that have a screw driver slot at the top....turn those in either directron to see what voltage line it affects and what direction to turn to make it go up. not all psu's have em....some older antecs and enermax's do...and the ttgi is a great cheap powerful psu that has a pot that adjusts the 5v and 12v line.

I just put the test pin/lead with a tip or whatever it is caled in english(looks like this http://www.elfa.se/images/highres/h8036.jpg DMM test leads anyhow) down in the atx connector so it makes contact with the cabels.
Works fine for me..

BE VERY CAREFUL WORKING IN AN OPENED PSU!
