Memory Testing and Overclocking:
The abit IP35-Pro has the second best latency scores of our test units thanks to very aggressive tRD settings. abit's Sandra unbuffered scores are around 2% lower than the ASUS and Gigabyte boards but as we will see, overall performance is still extremely competitive with these boards.
Q6600 9x266
Q6600 8x455 2GB
Q6600 8x450 & 8x455 4GB
We were able to reach a final 8x455FSB overclock with our Q6600. The first 8x455FSB screenshot is with the 2GB memory configuration set at DDR2-1092 at 4-4-4-12 timings. Memory voltage was set to 2.30V although the system ran fine at 2.275V except with Supreme Commander, which, would lock up at any voltage setting under 2.30V. Our CPU voltage was set at 1.50V and was at the absolute limit of our air cooling setup during the POST routine. The one problem we had with the board throughout testing with the Quad Core processors consisted of Vdrop/Vdroop levels of up to .08V under load. With additional cooling and increasing the CPU voltage to 1.53V (1.45V after Vdroop) the board was able to POST and complete our test suite at 8x470FSB.
The 4GB configuration was still able to reach 455FSB but only at a 1:1 memory ratio that resulted in a DDR2-910 speed with 4-4-4-10 memory timings. We were able to drop our memory voltage to 2.250V with this configuration while CPU voltage was dropped to 1.49V resulting in a 1.43V reading under load. We were able to run our memory at the 5:6 ratio but had to drop our FSB settings to 450 and loosen timings to 5-5-5-15. Our test results generally favored this configuration when using 4GB of memory as it exhibited better latencies and throughput compared to the 8x455FSB 4GB setup. A couple of CPU centric benchmarks still favored the slightly higher CPU speed but overall, most applications performed better with the 8x450FSB setup.
E6550 7x550
We were able to reach a final FSB setting of 555 with our E6550. Our 2GB memory configuration was set at 1:1 ratio with 5-4-4-12 timings. This will result in the board setting performance level (Read Delay) to 7 but required memory voltages to be set to 2.275V. The maximum MCH voltage is 1.72V, and 520FSB and higher required that setting with this particular CPU. CPU voltage was set to 1.46V with Vdrop/Vdroop realizing a final 1.41V during normal operation. The highest FSB we have been able to attain with this CPU is 570 on the DFI P35 board.
The overclocking capability of this motherboard is extremely good but more importantly, very easy. The board's stability will start to trail off when you are near its limits so there is feedback from the board before you go over the edge. The board does not overclock quite as well as the DFI P35 TR, Gigabyte GA-P35-DQ6, or the ASUS Blitz series of boards. However, unless you are trying to set overclocking records, the board will satisfy 95% of the users. If we could change one item with the overclocking capabilities, it would be excessive Vdroop with the quad core processors.

In this day and age, PCI LAN = fail.Dual PCI LAN = double fail.
Realtek ANYTHING does not belong on a board that advertises itself as a "Pro"
Whatever happened to the good old days where the south bridge had a MAC that just needed a PHY to have a network connection that was completely independent of other external buses? I know the ATI/AMD RD600 doesn't have a MAC and requires an external network adapter, the ICH9 has a gigabit MAC, and requires merely an Intel 82566 PHY chip to have a gigabit Ethernet connection.
For that matter, who here uses dual NICs? Please raise your hands and tell me what you use them for. Seems like a waste of power to use a computer for internet connection sharing, in the day and age of $25 wireless routers....

Right, so let me get this right.You give the IP35-Pro a gold award, and the DFI P35-TR2 a silver award?
The IP35-Pro had bigger vDroop, reaches a lower FSB with a Quad and scores a mark above the DFI?
I'm not disputing that it's a good board, after all it's cheaper than the DFI and has uGuru but these motherboards are for enthusiasts. The users who chuck the most expensive, best performing hardware into their online carts without a second thought.
So, I'm thinking a Vauxhall Zafira should score more than a Lotus Elise because hey! It's slower, costs less and can fit 7 people in it.
Add to that the fact the DFI P35 review walks all over the IP35-Pro one as it's also a more in depth guide into it's overclocking with the GTLREF settings etc.

It has been said that the vdroop on these boards is associated with inexperienced users *not* using a different 12v rail for the 4 pin PCIe AUX power connection. The only vdroop I had with my IP35-E and E6550 @ 3.33Ghz was a very small MCH vdroop, which was easily corrected in the BIOS by bumping the MCH voltage up one notch. I am also using a Power supply that is known to work well with the IP35 series.The award for this board is well warranted in my opinion, and I cannot help but wonder exactly how stable that DFI PoS is, and how easy it is to setup. I could care less if it runs at a slightly higher external clock if it is not stable, or is extremely hard to set up. ANYONE with half a brain can setup the IP35 boards with a reasonable OC in about 1 minute, and these boards work 100% out of the box the way they are intended, and are dahmed stable(meaning I have not experienced a single BSoD, or crash since this board made it into my system).
As for the 'bad' ethernet performance, ANYONE who is serious about their ethernet performance is going to be using either an Intel Pro 1000 desktop adapter, or an Intel pro 1000 server adapter, and not some PoS onboard ethernet. As for why dual ports ? Maybe someone wants to run their desktop on multiple subnets ? Ive done it before . . . it can be great for remote booting. Now tying the GbE port(s) to the PCI bus is a serious no no, I will agree with that.
Let me guess . ..you own said DFI P35-TR2 board ? If you like it, fine use it , be happy and quite whining about some review that is 'dis'n' your motherboard . . . and go wonder how serious overclockers on the ABIT forums have hit 4Ghz + with their E6600's on this board.

I didn't say the board doesn't warrant the review score, as I said, I know it's a good board but there are users on XS who have gotten a higher clock out of the P35-T2R after migrating from the IP35-Pro.How stable the DFI is? Very stable, it's been described as rock stable by C-N, BrotherEsau, Solarfall who are 3 regular posters in the thread over at XS. I didn't actually own the P35-TR2 when I posted my comment before, I don't actually currently have a PC due to having my PC343B custom modified for a dual water cooling loop. I made my observation on real end user experiences with the board. I've since received my DFI board though.

First of all, these AT mobo reviews are always way late, with endless forum posts by Mr. Key about hourly "bios updates" being emailed to him by manuf. Can't they test their own boards - why do they need a reviewer to spot a bug? Abit doesnt know about Vdroop??? Dont they test firewire thruput?I'm sick of motherboards that work 90%.
And I dont want to hear about buggered up bios for months - when you get a "bought in store" retail board, then review it, other than that, stifle yourself.
You practically sleep with these guys - where's your objectivity? Its not your job to help them bring out a working board. I mean, like they need Gary Key for input - what are THEIR engineers doing all this time?
And why is it after all these years that mobo makers still cannot create a lousy <1MB bios that works right out of the gate.
They are still shoving crap out the door and hoping it flies - eventually.
I say Gary Key must go - get someone who doesnt put out all those "teaser" blurbs. Maybe that's one reason why you only have 422 members online at this moment. Its so annoying.
And FWIW: Abit is skipping the X38

No, they aren't - in fact IX38 QuadGT DDR2 stock arrived in the UK today.
As for the dual PCI LAN there is a reason & it's a deliberate design decision - it's upto you whether it's right or wrong for you but as Gary said it won't affect the vast majority of people as it's still waaay faster than domestic broadband & also faster than a single hard drive can cope with.
By using PCI LAN on the Pro(the IP35-E & plain IP35 use PCI-E LAN) it means that you can use the x16 PCI-E slot & the x4 PCI-E slot & still have another x1 PCI-E slot active (the last PCI-E lane on the chipset is used for the JMicron) for use with a wifi card, soundcard etc.
Other boards from competitors disable other PCI-E slots when the x16 & x4 are used to their capacity.
Maybe not so important now when there are still relatively few x1 PCI-E cards available (although 1 of course is abit's AirPace wifi) but in a year or 2?

One of the negatives I've seen about this board in other reviews is its Firewire throughput, which is considerably slower than competitors.See here for example: http://www.bit-tech.net/hardware/2007/07/12/abit_i...">http://www.bit-tech.net/hardware/2007/07/12/abit_i...
This might be of importance to some people who use FireWire devices.
Heidfirst - Thursday, November 1, 2007 - link
there was a BIOS released after that which supposedly addressed the firewire transfer rate issue.crimson117 - Thursday, November 1, 2007 - link
At the start of the review you mentioned a problem with the heatsinks.Is abit planning to fix this? It sounds like kind of a serious thing that the heatsinks don't work properly out of the box in 2 of your 3 boards.
Gary Key - Saturday, November 3, 2007 - link
We have abit to screen their production process and to improve this design. We had one board that the PWM heatsink refused to make decent contact with the components and the other two were close to perfect. It could be manufacturing variations in the heatsink design or just plain bad quality control.
