I have a couple of buddies on XS that demonstrated what this board can do. I have a Q9650 sitting here (no time to install).

Both my mates were able to do just north of 500 FSb with a Q9650 on air (500x8). I am in the process of rebuilding a WC setup based on the Q9650 and its not unfeasible to get into the 4.4 to 4.5 range with the Q9650 on water with this board.

There are very few other boards (like 2) that can do 500 FSB with a quad and they both cost over $400.

I can tell you why I chose this MB...

While searching around on Newegg for a MB for my GF's PC, I seen the UD3R. I liked the colors a lot as blue is my colors, I also seen the words "Ultra Durable" LOL. The 2oz copper caught my eye and seems like a smart idea (or marketing scheme). I Googled the model and the first link I seen was on the XS forum and it was title something like "UD3P 670FSB benchable.". It was something like that, and as soon as I seen 670 FSB the research frenzy started. I started to see what quads were pulling and 500+ was pretty common for this MB... s I bought it and gave my GF my Mars.

Edit: It is funny that you mention WC because I am taking the trip to that side of the rig in March 09. I am not sure how well I will do as I will only have about 300.00 to spend on a whole WC system. On the other hand I could always get the expensive parts first then the cheaper parts later. One thing that did enter my mind is whether WC is even worth it. The CPU is near it's limits as I am already pumping about 1.38v, and the MB is also very near it's limits as I am not able to get it past 500 FSB w/o advanced tweaking.

QFT brother !! Thats how I roll out.

Here is that 600 !!

Holy ****! And its not even on a UD3P/R!

Rob why would I disable LLC? I was under the impression that it is better left on. With it on I see a vdroop of about .08. I have not tested it off yet and I am not able to right now. I am running memtest 86+ because I am trying to tighten my timings, and make sure it is error free.

Does anyone have any suggestion to get +500 FSB?

Line load calibration is not reccomended for 45nm chips in this scenario (high OC)
It may possibly overload your chip under stress and cause its rapid death .

I have been using p45 since August and def confirm these speculations.
65nm llc fine
45nm llc no go
imho.

I've had this board for about two weeks and seeing how hot this thread is made me unbox the other night. Here's my take...


In regards to heat dissipation:
-----------------------------
P5N32-E: Q6600 @ Stock @ 25C AMBIENT
(23C) #1-1:38C / #1-2:38C / #2-1:33C / #2-2:38C

EP45-UD3P: Q6600 @ Stock @ 25C AMBIENT
(21C) #1-1:30C / #1-2:30C / #2-1:28C / #2-2:30C

and until I can get a real sensor under there, my IR thermal gage tells me that my NB & SB are both in the same 30C temp range.
--------------

The thing that's got my panties in a bunch is the amount of control they give you over the DRAM settings. I haven't even gotten in there to play properly yet but this is going to finally give me the opportunity to finesse my timings rather than brute-forcing them with higher voltages...

Yeah, this board is the best DDR2 OCing board on the market to date! It even rivals the Rampage Extreme DDR3 which is $350!

Well, since I was able to get 8GB for $88 USD of some OCZ2F8004GK (4x2GB) DDR2-800 on a great deal a couple weeks ago, my goal will be to see how far along I can push these things with my Q6600.

Right now I've gotten them stable at their rated 5-4-4-18 @ 2T using only 1.8v simply by bumping up the Row Refresh Cycle timing (tRFC) up to 54. Considering they're rated at 2.1v and still under warranty up to 2.2v that gives me a lot of headroom to tighten things up when I *do* have to start upping my voltages. Unfortunately, that's probably the only part I'll be able to play with until after the New Year...

My thermal probe's are giving similar results.

If you saw my earlier post, this board set the world record with DDR2.
