I know you guys have the Intel core CPUs, but I have


I have a crap Intel mobo, D945GNT.
together with a overclocker CPU Pentium D 805 (2.66GHz) using stock cooler.

We all know that Intel boards do not have overclocking tweaks in BIOS.

Have checked Intel Desktop Control Center. It didnt list it support this board.

But I googled and found out that people still manage to overclock by using software.

Anyone here got experience on this?

Just wish to OC it to 166FSB(667) FSB or 3.32GHz cpu without cracking my wallet to buy new mobo or cooler.

Guys does anyone know Pentium D 805 @ default voltage with decent mobo + CM Hyper 212 cooler + DDR2 667 can overclock how high under non-air condition room? Rough figure lah so I can hit it with a good stability. Currently running @ 3.33Ghz tho.

I think it is ur RAM or FSB issue on ur 65nm Pentium D. it has nothing to do with Vcore. Increasing vcore wont change anything only increase power consumption.

I can run my old 90nm Pentium D 2.66GHz(533FSB) @ 3.33GHz(667 FSB) ROCK stable @ default voltage, using cooler master Hyper 212 @ non- Air cond room (Close casing), So ur newer Pentium D should be ok with 3.1GHz if it is not the FSB/RAM stopping u.

Currently I am asking/finding anyone here who got experience of overclocking this Pentium D further @ default voltage, seems I dont get answer at all -.-

honestly it is much harder to overclock that pentium D compared to the 2.66GHz ones. Since the 2.66ghz got low fsb setting high multiplier x20 My pentium D is also the old tech process 90nm ones.

FSB/RAM is definitely the one stopping you. I dont like OC my RAM and I didnt do any research on it, so u might wanna ask other here. I tot you can adjust the Ram ratio so it wont overclock pass 667.

ok I after a while I tried again on my CPU.

Got once I tried b4 Overclock to 3.5Ghz @ default clock (1.2v), playing CPU heavy use game(game that use heavy cpu) . I actually load the game 3 times. (*means same game open 3 and run triple at same time) After a while got some minor issue text artifact issue(the game graphic is rendered by CPU lol). but still stable didnt crash yet.

another time push to 3.6GHz @ default clock, able to boot to window, even play that game, but crash after a while.

According to tomshardware with increase voltage, this thing can push to 4.1GHz, default voltage @ 1.4v can get 3.6GHz (I dont know why their is 1.4, mine is 1.2v)

So conclusion is pentium D is not a bad overclocker, It is either Ram issue, or FSB or bad motherboard.

I am sticking back to 3.33GHz @ 333 FSB as I am happy to run it with FSB/Ram sync with my 667Mhz together
