How sensitive is a phenom to dips in the vcore?

post #1 of 19
Thread Starter 
I have a bad psu at 400watts noname junk, the 3v,5v and 12v all shows up at below the voltages and the vcore dips forth and back witihin like maybe 0.05-0.10. The processor is oc´d to 4ghz, i wonder how much it can do to the oc if i get a better psu,im getting the psu in my sig (its in the postoffice atm).
My primary goal with the better psu is to get rid of undervoltages and the vcore that varies up and down and hopefully maybe be able to lower my vcore a lil bit? Thoughts, reflections pls?

the vcore going back and forth is called Vdroop(or vdrop). It will happen even with a new powersupply(probably not as much though)

It's your motherboard, not the PSU.

The other one probably sucked too.

Vdroop is pretty common on low end boards.

True other mobo wasnt high end either! But does vdrop affect much in terms of maybe lowering the vcore for lower temps?

1 other question, dont wanna start new thread. I oc my 965 to 4ghz just by changing multiplier to *20 and the vcore to 1.5. Then its stable and all, doing prime 95 all night. Is it that simple nowadays? Havent overclocked in like 6 years or so!

Thread Starter 
doing prime as we speak for 45mins now, the option in prime that tests max temp. 57celcius and idle 40 celcius. But sometime even lower idle. But now primeing max temp all cores load is at 57celcius and idle is 40celcius. Max temp was 57c and low 38c.

So torrow when i am finished bigging my htpc, i will upgrade parts that are in sig now. Boring just to do 20*200, rasie vcore to 1.5 and then its over.....*cries...wasnt like this in good old days, givve me back my aircooled 2400+ mobile 35w with watercooling. Ohh well should complain, new goals mus be to try lower the vcore for temps and higher oc, through the fsb, and while on th fsb try getting the rams oc as well, no ideas to clock or messaround with the hht-link? What ive read/heard.

Cause u want the memorysclocked as well, northbridge i keep around 2000mt.

And i guess i will forced to adjust voltages for cp-nortbridge and others.

Idont want a easy overclock like that and with multiplier u just get max out of cpu.

CAN MY PSU Cause instability, below is the numbers on the psu i got in rig now!

Vcore:1.50V
+3.3v - 3.23v
+5v-4.85
+12v-11.38
