ludek Posted July 16, 2014 Posted July 16, 2014 Nice I need quickly to buy another motherboard. BTW. CL2.5 is the best on these chipsets. Quote
ObscureParadox Posted July 16, 2014 Posted July 16, 2014 Yeah I completely agree. CL3 gave me a lot more issues than CL2.5, I'm not sure if I was limited by the CPU or the NB but I'll find out when I test my second chip. If it is NB I'll start modding it soon Quote
ludek Posted July 16, 2014 Author Posted July 16, 2014 Well, it was wall ot my Celeron 1.2GHz. Today I did >350 MHz on P4C800 Dlx. Best vNB was around 1.82-1.87V, vCore best for this Northwood was 1.950-1.975 and CL2.5 of course http://valid.canardpc.com/gkelr9 vSB mod was needed. Raising vSB from 3.5V to around 3.75-3.9 gave me no USB freezes and more stability >340 MHz. Maybe it's time to do VTT mod (don't know if isn't it connected somewhere, eg. to vNB). Now I'm wondering how much "pct Intel OC" WRs are going to be done in comming month Quote
ObscureParadox Posted July 16, 2014 Posted July 16, 2014 hmm, I might try doing some vNB and vSB mods too and returning to this CPU some other time, that's if I can get my hands on more LN2 in the mean time Quote
ludek Posted July 16, 2014 Author Posted July 16, 2014 (edited) Sam - have you any ideas about adding any new mods ? Whad mods have you used to Abit IC7 ? Just realized that P4 478 have no VTT voltage. It's more interesting, because of my AsRock 775i65G is just newer version of P4i65G with 775 socket (865G chipet). 775i65G was able to run with xeon E5205 which is wolfdale 6 MB. As far it did ~350 MHz with E2140 core LINK. It's very interesting because of 775 CPUs have VTT, and 478 heven't. Maybe something like GTLREF voltage should be modded (2/3*VCC)... Â Â Edit: Just done ~350 MHz FSB with Dual Channel DDR1 (3:2) @ i875P (P4C800 dlx) at the same voltages. Seems like chipset wants to "better" conditions (LN2), no need to change my P4C800 to IC7 I think. Edited July 16, 2014 by ludek Quote

Crew Antinomy Posted July 17, 2014 Crew Posted July 17, 2014 ludek111, if you're using IC7, why not use hipro5's mods? Quote
Hyperhorn Posted July 18, 2014 Posted July 18, 2014 An amazing result and my personal highlight of 2014 (so far)! Congratulations! Quote
ObscureParadox Posted July 19, 2014 Posted July 19, 2014 Thanks for all the kind words everyone Quote
