If u don't get it after reading trough that tread u can PM me and I try to help u out as good as I can

I'm lazy to take my modded psu out so I just took picture of the whole case:)

The Mod : I took the up and side panels of psu and fixed the cover seen on pic. And also changed the fan with speed contrelled zalman...

upload the picture to you webspace or attach it

how can I upload my pics? I don't know. I tried the "img" button at post reply screen but I think I wortte it worngly...

click the "post reply" button, then click browse and find the image you want to upload, max size 100-200kb

are you talking about modding....? or tweaking the psu to give best performance?

Nice info Tumor!!
Very helpful and just what I needed.
But could you explain it in plain Dutch how to raise the 5V-rail??
this is not up my alley but still need to raise it. Is it difficult??

let us know first what PSU you've got

btw, you're also from Ieper :)

sorry, forgot: 450watt levicom
5V-rail is 4.836
what rail does geforce use?

3.3v rail

Did somebody ever had problems OC'ing because of his 5V-rail?
Because when I put my cpu above 175mhz; the 5V-rail becomes even less and asus probe shuts the computer down. Also, would this problem be solved if I use my dfi lanparty revB? (not installed because I'm waiting for my new HDD's)

Also, I'm not used to soldering, so is there anybody who wants to do it for me? I'll gladly pay for your work.

"Did somebody ever had problems OC'ing because of his 5V-rail?"

PSU brand is Skyhawk. Its 300 W and have one so called temp. controlled fan( always have the same noise). I'm gonna change it with a zalman and turn the rpm down...

Bu the way sorry for attaching image problems...

flash looking mobo! which one is that? :)

Its Soltek MRN-L. nForce 2 IGP based mobo,I think its not that much well known but i'm really like it,its has detailed OC features and the best I got 400 mhz bus speed by flashing rom!! U know normally all IGP nForces are 333mhz..

at this url u can find more pics....

thanks guys :D gonna open up my PSU now and prod around a bit with the scewdriver and such :D

so the mod was done:
on the plus side: 5V was 4.8, is now 5.2
on the bad side: 12V was 12.2, is now 12.9
these are not OC'ed so 12V will go up, also, I used a 50k trimmer en these timings are on maximum resistance, wich trimmer should I use to get lower voltages??

"these are not OC'ed so 12V will go up"

as soon as you start to overclock your lines will drop, not rise :)

I know that some hdd die (instantly) on 13.5v

just stay below 13V

ps. do u mean the voltages will rise under load?

my friend saaya ran his fortron PSU with his 12V line at +14V. his CDRW died but the HDD's are still fine

most electrical components stand a voltage toleration of 10%, so 13V is not out of spec

Interesting
Prolly make a dif between brand hdd but either way I wont be trying it.

Why 14V? does he need a high 5v rails?
I dont think there are any benefites of gogin higer then 5.5V?

and... is that hdd oc'ing? :)

HDD is not OC'ed.

all his voltage rails are very high just because overclocking gets much better then

When you oc, your lines will rise because of the extra output. Or am i mistaken??
Anyway, just put fsb to 200 -> 12V went up a little and 5V went down a little, so it really isn't a problem.
Just gonna put my new hdd's and mobo in and oc for real then.
Will keep you guys posted (if interested).

yea I kinda knew that. Just wanted to know if the higher voltage makes the hdd spin faster.

My rails: 3.63, 5.5, 12.75
so irl there a little bit higher.
I only mesured the 3.3 with no load right from the atx plug

But there a gfx missing in my pc so I can't play around with it anymore. Next week a new radeon arrives.
:king:

ok, rails stay stable, but I have a few other questions.
1. How much volt should the AGP-slot get?
2. What does the -12V do? Because it's pretty high.
thx, Randy

Agp runs of the 3.3rail. If u change the 3.3 rail fast u will kill your AGP slot and possible the card in it to.

I believe the -12V can be ignored.

U can go up or down 10%.
So 3.63, 5.5 and 13.2 would be safe.

Thats about my rails only I set the 12V to 12.75 to be safe

I didn't ask about the agp-rail to change it, but hardware doctor says that it gets 1.5V and indicates that it has to be between 1V and 2.5V. So it takes 1.5V from the 3.3-rail??? Is this correct?
