Hi folks have a few probs with overclocking my cpu I will list my setup.
XP Pro SP3
4x 512 MB DDR2 667 OCZ
Pentium D 930 3.0ghz
ECS C19 A SLI
9800gt 512mb Zotac
520 watt apevia PSU (my GFX card gave me some bullshit about not enough power so I now have in tandam 3 PSU)
200 Watt Supermicro PSU
350 Watt Dell PSU
Okay so here is my problem, I have gotten it to overclock to 3.3ghz on stock voltage, and it idles at an amazing 26C 35C max load. Okay so I go to change voltage right? Wrong I change it from 1.21v to 1.3v save changes and restart, guess what happens, pc starts up then turns off, so I reset the cmos and try an increment of .01v from 1.21v to 1.22v save changes and restart pc starts up and then shuts down, so I do entire process over witht he cpu at stock settings the same thing happens???????
this was before I had 2 other power supplies hooked up (because I am poor and because I know Electronics I hooked them up in parrallel) So it cant be that.... Any ideas, it is rock solid at 3.3ghz I just cant go higher because I cant change the fricking voltage...
i have a pD 930 and a asus p5wd2 premium, i think the stock voltage is 1,33 and same as you it's rock solid with 10% oc, then you need to increase voltage, to get 4,2ghz I used voltage on ~1,475 but to maintain stable I made a vdroop mod in my asus mobo.
sorry about my english and I hope you can understand me.
