PIV 2.8 C stuck @ 245 Mhz FSB

[mdualib]

Hi, I´ve just purchased a Epox 4PCA3+ and a PIV 2.8 C (Batch L319)... I was able to OC it to 245 Mhz, which means 3.430 Mhz, with stock voltage. Now, thats the catch: No matter what voltage I throw on it, it won´t go a single Mhz more over 245 Mhz... Is that correct? I know that temps are ok (I am using a Exos WC system, which, although not a superb cooling system, is ok for modest OCers like me )
I am using 2 x 256 mb OCZ Gold DC PC3700, a HIS 9800 Pro 256 Mb, a 2x Raptors 36 Gb (Raid 0) and a Pc PowerCool 510 Atx.
Is there anything else I can try here to go higher?
Thank you to all

my 2.8C did 245FSB max on PX865PE PRO2 with 1.52v real haven't tried it on 4PCA3+ yet, but on 4PCA3+ do you have Intel Fast and CPC enabled ? disable them and see how far you go ?

4PCA3+ voltages are weird you could be undervolting at 1.52v in bios read my thread at http://www.xtremesystems.org/forums/...threadid=17225

cl2 right? you need to lower your mem timings to 2.5 , maybe rise the vdimm to get higher.
