[zodden]

What do you guys make of this with LLC enabled on the UD3P. No upward spikes and long periods of stable volts. Look at the downward spikes, including one below 0.8v: How didn't the machine crash? It would seem impossible to me that it could run and finish the bench yet it did.

[v3rax]

I am happy that you started this thread because I just got this board and an E8400.

My first experiences with OC have resulted in a 3.8 OC thus far.

I know it is capable of going higher, but I am kind of new to overclocking and especially this BIOS.

If anyone out there has began using this board and have been overclocking, I would sure appreciate some pointers on BIOS settings in order to go higher than 3.8.

The area of the BIOS that is used for OC has some things I am not familiar with and I am sure there are combos/settings that will allow me to go higher.

I can't wait to see some more info start showing up on this thread, this is an AWESOME board.

clearly that is not possible >> 4GHz at 0.8v hehehe
must be the application going a bit crazy heheheh

[Flinch]

I'm noticing some voltage oddities with my Q9650 and UD3P.

I set the voltage in the bios at 1.33 and at the desktop with cpu-z it shows 1.23-1.24, somethings just not right with that picture.

I was googling for some answers and came across a guy at [H] that's seeing the same huge drop from the bios settings to what cpu-z is showing

[dinos22]

that sound like vdroop and vdrop that you would commonly see on boards

what about LLC enabled?

[RIRed48]

Wow, I'm only on Page 1 of this thread...and it's very good...

I'm about to get this UD3P MB, and I already have an E8400. I have some learning to do before going for any significant OC's with it... ( where are my reading glasses...)

[method526]

does the UD3P and UD3R have a CMOS switch/jumper that's easy to access in the back port?

[mreld3r]

Great clock Viper

does the UD3P and UD3R have a CMOS switch/jumper that's easy to access in the back port?

absolutely not! You gotta shove a screwdriver in between the pins to short them out. OR; you could get a jumper to close the pins. Which; by the way,
doesn't come with the board. Although 'everyone has a lotta jumpers, im sure'.
Kinda crappy really; but I have only had to reset my bios once so far, so.....
good in that respect.

[anniku989]

does the UD3P and UD3R have a CMOS switch/jumper that's easy to access in the back port?

I wouldn't consider a cmos clear jumper placed in the back i/o panel easy to get to, but no it doesn't have one. Gotta pull the battery (which is under the first video card) or put a jumper on the two pins at the bottom right of the board

[almighty15]

Is this thread also for EP45-Extreme?

I have one but can't find a thread for it

how should i get stable?

also why do the vcore keep changing from 1.344v to 1.360v then 1.344v in cpu-z when under prime95 load

thanks!!!

raise your channel A & B ref up to 1.05 or leave them on auto

Is this thread also for EP45-Extreme?

I have one but can't find a thread for it

Look here for EP45 Extreme :

EP 45 Extreme by EVA 2000

Soooo much info like always with Super George's reviews

[DeltZ]

I give up!
I've got a unique retarded wall at 1000mhz memory speed. Tried two sets of ram. One which worked up to 1200mhz before. But there's nothing i can do to get it stable at even 1066 or 1100.

argh! Useless memory controller/mobo peculiarity. Final result: E8400 @ 4ghz and 4gb ram at 1000mhz...or 8gb since I have an extra set of ram. what a waste!

[strange|ife]

does anyone have a link to bios templates

and maybe something explaining MCH Ref , CPU ref values.

this board is quite nice, havent had much time to play with it, but had the FSB up to 475, but had a reboot loop several times. I pulled the battery, and ended up getting distracted with some other stuff i need to do. Will get more time tomorrow night to toy around. I did read some people had problems with FB bios. I think i have Fb or F8..i forget now. The board is rev 1.6 though, bios is dated May 2009.

this thread is huge..it will take me a month to dig through it all

OH its the UD3P btw

I had the same problem with an Asus P5Q Deluxe. It turned out to be a software problem. I shorted cmos and pulled the battery for a few minutes and flashed bios. I also formated my drives, so Im not sure exactly what my problem was but that cleared it up.
BTW, this board looks kick ass. I want it!
