@cryptik, im not sure either, but on this board i was having issues w/ way to high volt until i tried zoddens suggestion about mch ref setting @0.75 now im able to use much more acceptable volts with nice clock resuts.problem im having now is going above 519fsb even w/mem@1/1 or5/6 without errors not sure if its not enough volt for vdimm or not. ive gone all the way up to 2.15,but im not sure how safe it is to go higher. well heres the best i can get so far.any input you could give would be appreciated. thanks

Found a bug on this board, it wont boot with something installed on the first pci slot on top of the 2nd pci- 16x slot, it never ending cold boots., bottom one worked fine. Anyone else have this?

Does this board (UD3P) have a NB temp sensor? In easytune, I see a cpu and a "system" temp. The system temp stays right around 32C on my board regardless of load or voltages that I've tried (I'm using the stock NB/mosfet cooler). But everest reports a "motherboard" temp that spikes to about 50C under orthos load- could this be the NB temp?

And as far as the stock cooling on the board, doesn't the blue metal plate covering the heatsinks block air contact with the underlying heatsink fins? It does have nice bling effect, but it seems to be counterproductive to heat dissipation.

On the plus side, I was able to find a use for my 4x1gb OCZ flex pc9600 RAM- I got my e8400 to 4GHz (500x8) with this memory at 1200MHz (5-5-5-15) stable for 12hrs of orthos blend on the first try using the info I've seen posted in this thread.

No NB sensor

this Gigabyte board seems to overclock ok with 4 dimm slots filled.

heres some watercolling Pics from me and my current system settings. FSB 505 along with DDR2-1263 with relaxed timings works fine here.

[bigslappy]

nice thread i'm sub'd

Nice Job. Can you post a bios template and some easytune? Thanks! Also if you have time may C&P this to the UD3 Quad thread. Again nice work.
I havent been able get my 9650 prime stable @ 500+ for more than a few hours on any multi. Maybe your settings will help.

could someone please help me out with cpu ref/voltages on this board. coming from the P5Q-deluxe and maximusII i was almost understanding it,but on this board it only has the one cpu ref adjustment. unlike the before stated boards P5Q had 0.635 0/3-0.667 1/4 settings and the maxII had adjustment in mv(-40).any help would be welcome. thank you

[bigslappy]

Just posted my review, check out the voltage regulation section. It should have everything you are looking for

Great Review, Good Job !

I'm not 100% sure but I believe it should be 0.64 * Vtt (aka CPU Termination). I found this over at TweakTown. In the general BIOS template, the mod has

Motherboard Voltage Control
Voltage Type.………... Manual
CPU
CPU Vcore….……….........................:
CPU Termination…..... 1.200V*.......: <<< Leave
CPU PLL…………………....1.500V*.......: <<< Leave
CPU Referen.…………....0.755V*.......: <<< .64% Of Vtt (Termination above) Auto Will set this correctly

CPU Reference2………,,0.800V*.......:<<< .67% Of Vtt (Termination above) Auto Will set this correctly

Now obviously we are only given CPU Reference. Seeing as how the UD3 defaults at ~0.76V, I'm guessing that CPU Reference he listed is the same as ours.

Thanks for link... I agree with "bigslappy"... nice review.

[radaja]

finally made 533fsb.just needed to give more volts to my ram.

[seban]

Quick question about FAN jacks and control.

So there are 4 fan ports on MB and are they all controllable through Software from Win lvl?

Thanks

[radaja]

@simpleTECH, thanks for the info but im still kinda confused as to how it works

[Sparda]

So I guess cpu and mch reference can be tuned understandably via ET6 because I need to put cpu reference above 0.85 and mch reference above 0.9 in BIOS to be able to boot at 500fsb. So I just put it on auto in BIOS.

[nugzo]

finally made 533fsb.just needed to give more volts to my ram.

Try ram at 1066 1:1 with pl9. I bet its almost as fast as what you have now and less stress.

[radaja]

i cant set pl9 w1:1 divider above 450 fsb for some reason . it just wont boot,then when i go back in bios get the red OC failure box, but i was able to drop to pl8 with 5:6 divider.

Well I just found another bug with this board. It seems that you cannot put a sound card on the second PCI slot (PCI2). When I was trying to install the X-Fi drivers, it would freeze or end up with a weird message. Then I got constant lock-ups and sometimes I was unable to boot into Windows.

So I put my card on the first PCI slot (PCI1) and got everything working. :/

Kind of sucks because it's right next to my GTX... limiting airflow and more or likely will heat up much quicker.

[1_budz]

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

Check out the GSkill official website it does support Gigabyte P45 mobo's.

Are you using Vista or XP? I ask because I had similar problems with the X-Fi on my DFI board with XP64 on the PCI slots ... wondering if it was a software prob with Creative, not the board ...

I am ordering this Gigabyte board to run my QX9770 with (water-cooled) and I am hoping for some nice results ...

[AKHandyman]

Elektrosadist- What EK block did you use for your NB? I am planning on getting this board and will want to water-cool the NB in conjunction with my OCZ FLEX II memory. Is it the EK-NB S-MAX?

XP Pro x86 (SP3).

I believe it's because of a conflict with other IRQ's associated with the PCI bus. When I go into the BIOS, it says that the USB Mass Storage and other devices are in use with that slot. But PCI1 slot shows nothing.

No huge biggie as I will eventually get the X-Fi Titanium.

[MaximumPig]

I have a stupid question: how do I set mem dividers of more than 1:1 on this board (i.e., mem slower than FSB)? I can figure out 5:6 by using a 2.4 multi in the 333mhz strap but there are no multipliers that would let me use 6:5 (for example).

Also, I have 4x1GB of mediocre memory. I can get 430FSB++ with only 2 sticks in but with 4 I get stuck at 410 or so, so obviously the limiting factor is that something can't handle 4 sticks but 2 are ok. Short of upgrading to 2x2GB, are there any tweaks to MCH or DRAM voltage or other settings in BIOS that would push that up a littles?


Thanks in advance.

[radaja]

@nugzo, what do you have set for memory performance mode for 1:1 pl9? (standard,turbo, extreme). cause i cant seem to get it to run 1:1 pl9above 450fsb. maybe you could post all your settings in the bios for me.thank you.
