Nice !! Well,Do you plan to get higher that speed ? For my E8600 I need above 1.60 VTT boot up to window in FSB 500+, I'm not sure for for around FSB 450. I'll try soon.

But for over 4.33 GHZ I can't get any stable at all.

no.,i think not nice bro.,because the VTT quite high i think.,i heard they say better not use VTT over 1.35..now 1.42 already..

Sure may be not Nice for you. but I don't know why this board need very much VTT to boot up compare with my old mobo maximus II formula.(for my E8600)and I need at least 1.60 to get on Window, but for you 1.42 is OK for me.

yes bro.,me also think why dis board need very much VTT.,but i also they can get below 1.30.,maybe we not have a good luck..

I have been tweaking for about 7 days now. It has been a to get Prime/Orthos stable at higher FSB with acceptable (for me) voltages but I finally accomplished it. I was able to do 20 runs of linpack, 2 hours of OCCT, super-pi runs and prime small ffts for an 18 hour run before I manually halted. Blend is what I had a problem with. I tried almost every combo I could.

Maybe this will help somebody else. When I lowered my MCH reference to .70 I finally got 24 hours of Orthos blend.

So here is my new 24/7 settings.

I've had this board up and running an hour. I previously had 2-Striker 2 Formulas, 1-MSI P7N diamond, 1-EVGA 780 FTW,
2- Maximus 2 formulas and 1- Rampage Extreme.My goal was a Q9650 4500Mhz 500x9 on Air. None of the other boards could do it.
Closest stable was 490x9 with the MIIF. I've only had 1 BSOD with this board and it only took an hour for the beginnings of an oustanding OC session.
This is what i call FUN! I've booted into windows at 533X8 only to get my 1 and only BSOD after 10-15 seconds.
That was with no extra voltage over what i'm running now. I'll be checking for max FSB Next.

Thanks to napalm for some bios settings.

[radaja]

thanks zodden for your settings. it really helped lower my volts and up my fsb.

[ezaleina]

nice radaja.,this is my result.,no so impressive.,because cannot get 450fsb..need to pump vcore to 1.45v to get it..so this the last i can manage..

[derekd]

I have a UD3R, and it seems like for most of the 120mm CPU fans on Newegg there is a review that says it didn't fit on this model because the on-board heatsinks got in the way.

Has anyone been able to put a 120mm non-stock fan on their CPU?

[zodden]

thanks zodden for your settings. it really helped lower my volts and up my fsb.

Glad I could help! Looking good

[BuGjAE]

Glad to you radaja & ezaleina, Thanks zodden for your info, I just notice that CPU VTT is relate to MCH reference (if you set MCH ref. to non auto)
And now I can boot up success to window at VTT 1.28 and MCH ref around 0.64 ( but show in ET6 0.90) .Still not test a stable yet. But this is
first time I can boot up to window with below 1.60 VTT, I'll post the test later.

glad to u also bro Bugjae..can you upload your screen shot.,maybe we can share your setting if u don mind..

[radaja]

i set what zodden did with the mch reference voltage to o.750 in bios and in et6 shows 0.700 and i was able to boot with vtt lower than 1.42

[golfjam]

Man, there are so many threads about this mobo that it's hard to keep up!

Can you se it now?
NEED HELP

[radaja]

@zodden,on that 525fsb run you posted you were able to run pl9 with 1/1 ? i thought the lowest pl on the 1/1 divider above 450 fsb was pl10 on the P45 chip. the lowest i could do on my maxII at 467fsb @1/1 was pl10.

[CryptiK]

Hey nugzo, not bad at all, I notice you are using 1.6v on the MCH on the UD3P, just wondering if you tried up to 1.6 vNB on the M2F when trying for max stable FSB? What vNB were you using on the M2F for 490 FSB stable?

[Dymblos]

why gigabyte boards dont support G.skill and Crucial Ballistix DDR2 rams?
I have two set 2x2gb 8500 of g.skill and crucial. .and im planning buy a new board, but gigabyte dont support them ... anyway Asus support all ddr2 brand, maybe my next board will be Asus P5Q series

I try to run HyperPI ,Orthos ,Memtest at the same time like crazy to find where unstable may happen!
Notice that when pull up the CPU VTT the MCH REF 'll up also.
I doubt that why AUTO voltage setting for this board seem unstable even @stock speed (E8600 3.33 Mhz)

Anyway I found 1 error memtest in this setting.

As far as any hard-wired restrictions- maybe there is but it must not be at 9. Maybe the restriction starts at 8 since I couldn't even post but I don't know. From what I have read here though I think you can take it as low as your system lets you. For me 9 is as low as I was able to go. I didn't mess around with the pull ins and stuff from that bios page because frankly I don't understand it enough to mess with it.

Maybe CryptiK can answer your question as he knows more about this stuff then I do.

[radaja]

@bugjae, great job that looks awesome!

[zodden]

He Guy I'm try @zodden BIOS setting and set 0.75 Mch Reference is working great!!

Wow that's some awesome clocks! This is a special board.

[dannyuk32]

Well I just got a UD3R.
In comparison to my Asus P5Q-E that I had I'm disappointed with some things ... the fit isn't as good. The I\O panel fit \ connections is poor and getting my Nvidia 260 GTX to sit was difficult to say the least and it doesn't feel secure. .

[Sparda]

If anybody wonder about an aftermarket cooler for the mosfet. The old thermalright HR02-U//S that fit maximus and rampage formula and EK asus 3a backplate also fit this board.(Note that on thermalright website only the I/O mosfet fit)
Forced me to use it since I have some clearance problem with heatsink and the stock jigabyte cooler. The blue color look cool though. :P
