**OFFICIAL Gigabyte UD3 P45 Yorkfield (45nm Quads) OC and Discussion Thread**

[seban]

Hi,

My random q9550 e0 is coming to me by mail - I would be happy to reach 4ghz 24/7 with it.

Nugzo as you had few M2F and others boards which would you suggest for my target GHz and also easiness of achieving it.

Ofc all other members opinions are more then welcome.

Thanks

heres some watercooling Pics from me and my current system settings. FSB 505 along with DDR2-1263 with relaxed timings works fine here. I found Bios F4 to be the most stable and clockable with Quad and this Board. F5A caused BSOD for me. The CPU i have was pretested in a shop with FSB 471 @ 4G on air and i pumped it a little more. I also chatted a long while with the shop owner there and he said he also tested the F4, f4PI and the F5A Bios and the most reliable for Quads is the F4. I will later make a SS with ET6. And i don't know how extend you guys test, i do Prime for like 6h OCCT for 3h as well as 20 runs of the INTELBURNTEST and then i run all synthetic benchmarks i have (3dmark and pcmark stuff, superpi, everest, sandra and some more). After all that is passed i just use the system (surfing gaming benching a lil)and when i dont get a blue screen for some weeks i refeer to this as stable. I just say this cause i know some of you do Prime for days.

Thanks for the detailed info. I will try your settings now. Did you set the CPU reference in the bios or with easytune?

Try Elektrosadists Template. Looks to be exactly what u need.

Try Elektrosadists Template. Looks to be exactly what u need.

i do all things in bios. I just installed easy tune 6 and now imma confused. Which would be the correct voltages the one in the bios or in easytune. f.e my dram term and ref is at 0,94v but when i open easy tune it says 0,76v. Can anyone confirm this that the board also undervolts the DRAM Ref an DRAM Term v (besides the CPU & RAM v drops)?

i tried to set my dram term and ref in bios as well as cpu&mch ref. wont post for me

,-(
well works for me, thats what counts. lol.

then again my system is slightly different and the cpu differs also in there quality.
