hi all
i run my 4600 at 250x11 and my ram supprots up to 250mhz. my ultra D DFI seems to undervolt (according to cpu-z) so I am running 1.375v i nthe bios and still cpu-z says it is just under 1.35v. anyway i am getting a prime fail on one core after 6hours dual prime and I am just wondering is prime a cpu-z stress test of the entire system, as at such a mild overclock I am not sure what the problem is. my psu is the 450w from the sonata2 and my ram is running in spec at rated 3448 at 250mhz. any help would be much appreciated :)

also my the Hyper transport is at 250x4=2000
 
was thinking that might be it. but that means i need 1.4volts for 2.5ghz:( it also took 1.75v to get stable at 2.75ghz, what a ***p overclocker i got.

anyone got any comments on the DFI undervolting. i have had two of these boards and cpu-z reported the voltage to be slightly undervolted on both, or is cpu-z talking rubbish, thanks
 
i had a look on there a while ago, they were helpful but went on about the psu a bit i tell ya :p

i hope the psu is ok :confused: me mates got a conroe x1900xt 6hard drives tv card the lot in his sonata2

what app you recommend for the voltage reading??? :)
 
looks like a new psu will have to be bought soon then :) true he isnt powering a DFI. i only got the sonata2 as ive read many reviews saying its a good psu (a strong antec branded one), but of course if these rumours of the new radeons needing 250w per card a new psu will deffo be needed will have a look on the DFI disk now thanks for the help :D
 
the app reports the same volts as cpu-z, so board must be slightly undervolting. It shows temps as the same as my bios, however core temp beta says they are much higher (around 66degrees under load).
