BAM!




And one more, I can probably drop the voltage core on this one but whatever.



LOVE THIS BOARD!

Why is the PCI-Express at 8x?

I was waiting for that one because I noticed it when I was looking over it. I have a Crossfire setup. Check my signature below.

truehighroller,looks like your enjoying the UD3P.500+fsb is great
with a quad

Can someone tell my why my PC is going to sleep while running Prime95?

[truehighroller]

Turn it off it Windows yet? Also turn it off in the BIOS settings yet?

Different subject, I am looking in to water coling but, I don't know yet.. I am still debating. If I am going to get water cooling I am going for the best stuff that is for sure. I was looking around today at blocks and pumps and radiators. I might be just pushing my cooler further then what it can handle and the temps might actually be swell.

I will under clock it to 3.8GHz and see if my temps are close to my old Q9450 and if they are then I am pushing it is my guess and I will probably buy a water cooling setup. Maybe I can find a formula to use or a calculator tha will tell me the Wattage.

Edit:

Found calculator, I am burning 189 - 195 Watts. I can not, find how ever the rating for the Thermalright 120 extreme.

You may have to change the power settings in control panel.

[truehighroller]

I need better cooling. I put it at 8 x 485 and it is where my other one was, at that speed temperature wise.

Edit:

Spoke to soon again, it is the chip. Is it possible that the sensors in it are whacked out? It was reaching upward of 94c at 3.8GHz. VDroop doesn't cause that right? This board has a .04v droop.

Wow, what a great thread. I find myself needing a new mobo for my Q9450 & OCZ Blade low voltage DDR2 1066 setup after frying my Asus Maximus Formula (X38) setup (my fault, long story). I really don't need X38 features and after searching a bit found this thread showing a really good line of P45 mobo's that appear to provide a great value.

So – my question – other than specific features such as Raid support or Xfire is there any significant difference between the various P45-UD3 mobo's? I'm not running Xfire and I don't need DDR3 support so I'm a bit puzzled at the choices – they all appear to be solid and I can't see the difference between, say, going with the lower cost UD3L (in DDR2 variety) vs a UD3P or UD3R (obviously the latter having RAID). So – am I missing anything?

I'll be mounting a Prolimatech Megahalems cooler so if there's any clearance issues that would be good to know – had to mount sideways on the Maximus but that was OK as it's in a CM690 case so it blew straight up towards the top where I have exhaust fans mounted.

Thanks!

P has Crossifre at 8x by 8x speeds the R doesn't. I would get one of these two if I was you, they say you get what you pay for.

[Karl_in_Chicago]

I don't need the Xfire (and, really, if I was going to Xfire I'd probably want to do it at x16 X 2) and I'm ambivalent about RAID support (I've had RAID chipsets on my last two systems but have yet to deploy a RAID group). Other than that I'm not seeing what the differentiators are between the boards.

As far as getting what you pay for . . . I mean, being UD3 series, they all have the extra copper PCB's, the better caps, as well as the carryovers from UD2 like lower RDS MOSFETs, ferrite choke, etc. - right?

So as I review the offerings on Newegg (typically representative of fair "street" pricing) I see:

GA-EP45-UD3R for $119.99 less $15 rebate, total of $104.99

GA-EP45-UD3P for $134.99 less $20 rebate, total of $114.99

GA-EP45-UD3L for $109.99 less $15 rebate, total $94.99

GA-EP45C-UD3R for $129.99 less $20 rebate, total $109.99

After the base UD3 features that I expect all of them share (correct me if I'm wrong) it would appear that the "extras" are:

EP45-UD3R has RAID support (ICH10R)
EP45-UD3P has Xfire and RAID support
EP45C-UD3R has support for DDR3 & DDR2 and RAID
EP45-UD3L has none of the above and may not have Firewire (couldn't confirm, all the rest have Firewire)

So - am I missing anything else? It's not *really* the money, I'm just frugal, and typically look at the cost differences in terms of . . . how much beer would that buy? So if I don't need Xfire or RAID is there something else I'm just not catching? Thanks again.

if you can afford the UD3R,its your best bet.its a proven clocker
i dont know much about the UD3L and ddr3 are bad boards

[bluestang]

Stay away from the C -- Combo DDR2/DDR3 board. One can say take the UD3R over the UD3L as it has better HS's on the board components. And it has an 8 pin CPU power connector unlike the 4 pin on the UD3L. However I have a GA-EP45T-UD3LR (DDR3 version) and it only has 4 pin CPU power and I'm running it at 8x500 (see sig). I'd go for the UD3R cause of the better cooling HS.

Edit:
Oh, and BIOS is a little more cut down on the UD3L series in the M.I.T. section.

Why, is the combo board bad?

I actually find the EP45C a breeze, and but for my crappy psu and ram, as well as the fact that I'm on air, I could probably be taking down some records. I've primed as high as 4.35Ghz already and clockgened to 4.6Ghz with the settings below oc:

Great info, thank you. OK, going to order the UD3R then.

Anyone fit a Megahalems on one of these?

yes

[Karl_in_Chicago]

yes

OK, a direct answer to my question.

In which direction did you orient the cooler - "traditional" with the fan(s) blowing to the "back" of the mobo or "sideways" with the flow to the right side of the mobo? On my ASUS Maximus I had to go sideways - wondering about clearance issues on the EP45-UD3 that I may need to plan for. Either way works for me as I have exhaust fans in both the top and back of my CM-690 - I just like to have these things planned out as much as possible. Any info you could share would be welcome. TIA.

[The Viper]

traditional...one panaflo 38mm push config

@Zuck, Nice work! How's the bandwith in Everest?

[truehighroller]

Alright different chip now again,. The other one was pushing 94c at 3.5GHz. This one is a 170 batch and has a vid of 1.2375 which is ok because it is running a hell of a lot cooler then the other one. This one is running Prime95 right now @ 480 x 8.5 4GHz and a temperature of 65c on the hottest core, muchhhh better. I will push it more here in a little bit. Hoping I can set my games up on my new install and play some now, finally..

hi guys
love the overclocks
but i have a problem with my overclock
here is the specs of my rig
gigabite ep45ud3r
intel q9450 2.66 @3.5 with true extreme 120 2x silenx 120mm 90cfm fans in push pull temp 63c max with intel burn test
ocz ddr2 1066 @1055 2x2gb
asus gtx280
enermax 1kw psu

im having problems getting the cpu over 3.6 and i have took the voltage to 1.3v and i cant get is stable
i dont really know about the motherbord voltages and whats (safe) so i dont like to mess about just incase i damage the mobo i reall wanted to hit 4ghz but can i do it with air and what temp is really to high for the overclock

thanks to anyone that can help me

Try just setting your CPU voltage to 1.35 and your chipset to 1.4 and then your memory to 2.1 and leave everything else auto except the performance level and your memory strap. All of your gtls at auto at first. Mine I have noticed this for a fact now after having this motherboard for about a week now that if I set the gtls my self at first it won't boot, leave them at auto and vualua boot.

I also noticed that if I leave my memory at 1.8v it won't boot either. I think the motherboard thinks because the memory is running at 1150MHz it needs 2.1 and it won't let me boot with out it set to that. Kind of a weird thing but, whatever the memory is running cool at that voltage any way. Hope that helps.

Once you get a feel for what to set the volts to the lowest possible volts, then start setting your gtls one by one checking for stability every time you make a change until you have everything else manually set as well.

Guys I just had the weirdest issue with this board. Upping the PCI freq to 105 resulted in a continuous reboot, anyone else ever have this issue?

Not sure why you would run it that high. 100-101 is what i use.

UD3 series can only run till 102Mhz_PCI_e

Extreme series can go much higher.
