    No way. No heatpipe!

    Comparison of 3P and 3R

    Looks like they are the same board, except the P has 2 PCI x 16 2.0 slots. The R has an extra PCI slot, but only one x16 2.0 slot.

    Anywho, my EP45-UD3P seems to be worth the $114 I paid. It is extremely forgiving and I am told can handle FSB up to 2230MHz without catastrophe.

    The UD3R does have a heatpipe sink. The heatpipe connects the northbridge to the MOSFETS near the I/O plate.The board is identical in every way to the UD3P apart from it only has one PCIe slot. You must be getting it confused with either the EP45-UD3 or the UD3LR.


    This is the EP45-UD3R:

    **Edit** It doesn't have the extensive heat piping that the DS4 has, but to be honest it's utterly pointless. The chipset doesn't produce enough heat to warrant cooling that over the top. If you want meat with no sauce, get the UD3R, if you want a yesterday's tech board with trimmings dressed up as a boy racer's board, get the DS4. The UD3R will outperform it in an overclocking situation by a country mile. The board contains twice the ammount of copper in each of the two copper layers, meaning the board itself is one giant heatsink. Differences in temperature between even the most heatpipe heavy of P45's can be upward of 10c. Gigabyte claim it can be up to 50c cooler, but wven I think that's a bit far fetched.

    I believe the 50c cooler refers to the interconnects in the board, not component temps.

    Thank you Psycho, I will definitetely take a closer look :)

    Damn I hate stuff I don't want :) PCI slots, ew. My 4870 with cooling takes at least two slots, and I have extra network card and intend to buy a soundcard as well. This is impossible to plug in to my current P35.
    edit - and looks equally impossible on this one too :(

    Btw the hetpipe connected coolers on it tend to get very hot! So I assumed it's better than the system we can see in the picture above.

    Thanks for clearing that up. I kind of thought it was actual PCB temp, but I still thought 50c less was an exageration. Then again, I've never taken a digital temp probe to the PCB of another board, so I don't know... could be true.

    If you'd like to have all your PCIe slots available for use (three of them) you could get the UD3P. Installing your 4870 in PCIe2 (the orange slot) will give you loads of space for your expansion cards. Note that although PCIe2 is only an 8x connection, this is more than enough for a single card, and it won't effect performance in the slightest. Thinking about it... if a dual GPU isn't held back by a 16X connection, a single GPU won't be held back by an 8x connection.

    I've had northbridge volts as high as 1.48, and the heat produced isn't too great. You can get 500FSB out of the board on less than 1.3V, at which point the sinks are barely warm to touch. The blue covers on the top MOSFET and northbridge sinks come off too. I removed mine, they were just held on with a little doublesided tape. This exposes the fins to the air and no doubt aids further in cooling.

    The board has PCI-e 2.0, right? That means that x8 slot gives bandwidth of 4GB/s. Now, how much does 4870 need? I opened the Comparison of ATI graphics processing units - Wikipedia, the free encyclopedia but got totally lost - no idea what number to look at. Can you give me some pointers?

    As for the second part of your post - did you mean you remove the heatsinks completely, or?...

    There are no firm figures, but you won't see any performance loss running your card on an 8x PCIe bus. Logically speaking, if a 4870x2 sends twice as much data over the bus, and isn't limited by 16x, then a 4870, sending 1/2 the data of an x2 will be fine on an 8x bus. The UD3P is designed for a crossfire setup with two single GPU cards. 8x/8x on both lanes is perfect for this. The board will only struggle if you try for CrossfireX or 3-Way Crossfire, as each dual GPU will need closer to 16x.

    No, The heat sinks are still on my board. You see in the previous picture, the two sinks with "Gigabyte" and "Ultra Durable" on them? Those are metal plates on top of regular finned sinks. I figured these plates were blocking some air flow, so I removed them. Ran Prime95 on Large FFT for 30min to warm everything up, powered down and pulled the plates off with my fingers. They came off with minimal force, and the sinks underneath look rather good, they're gun metal grey.

    Actual picture of the removed top plates:

    That is good news!
    Did you try to check how are the heatsinks attached to the board? I am curious whether the dreaded two-side thermal tape is present or not - and if yes, maybe removing it and using normal paste would make any difference...


    Btw I assume P45 is the best chipset for me if I don't want i7 at all, right?
