Abit IP35 Pro Intel socket 775 Motherboard Page: 1

Abit have a rich history of making motherboards that get enthusiasts excited. The AW9D Max brought those memories back and the IN9 32x Max cemented the fact that abit were once again one of the big players on the scene with a great motherboard.

Then IP35 Pro is perhaps aimed at the more discerning enthusiast, those with a mind for stability and performance. Based on the Intel P35 platform this is a motherboard that screams abit...and shows us just how well they can make their boards.


As usual abit have put a slightly confusing and strange front to their product with the IP35, showing a rugged snake-like truck on the front cover of the packaging. Having said that the back has a lot of well-laid out information on the motherboard.

abit ip35 pro abit ip35 pro packaging

The packaging inside the box is again typical abit with compartments for the manual and also for the accessories.

abit ip25 pro

The motheboard and it's contents are well protected but unlike the Max boards you get the impression abit have focused on content and not appearance so much. This isn't to say the board isn't as well packaged, just that it doesn't feel as "special" as a Max board.


Abit have again gone for delivering a "not quite" Max package with this board. although everything is there that you would expect so see in a decent board.

We have:

* 5 x SATA connectors
* 1 x IDE HDD Cable
* 1 x FSS Cable
* 1 x USB/Firewire backplate IO extension
* 1 x Motherboard Driver CD and manual
* abit µGuru guide
* IP35Pro User's manual
* Quick install sheet

Not a bad bundle but lacking in a couple of the extra things that the Max bundles seem to have in them.

abit ip35 pro

Still, there's a load there that you would need and I don't really see a normal customer complaining at a lack of bundle, espeically considering this motherboard is significantly cheaper than the Max series.

Abit IP35 Pro Close-up

The Abit IP35 Pro is one of the best laid out motherboards I have ever encountered. I opened the box and immediately the board spoke to me of very little clutter and lots of space to spread out my "stuff".

abit IP35 Pro abit ip35 pro markings

The board is clothed in a nice shade of blue, and despite my misgivings with blue, I do actually like it. The heatsink assembly is well-formed and doesn't get in the way of anything and all capacitors are solid-state, meaning more stability and longer lasting. Further to this, it does keep the chipset fairly cool even under some hard overclocking. I only felt it was holding me back at very high volts, so good work on that Abit.

abit ip35 pro ram

The RAM slots are a good distance from the CPU slot and the ATX power is on the edge of the board as it should be.

abit ip35 pro sata abit ip35 pro

The SATA ports are turned 90° around to allow for a graphics card to be inserted (even the 8800 Ultra and 8800 GTX fit here with ease), as is the IDE connector. The battery is in a slightly dodgy position but with an external clear CMOS switch this hasn't come up as an issue in our testing. Abit have again opted for the classic LED error panel to show you what you've done wrong and the FDD connector sits right in the corner of the board.

Going on to the connectors on the side of the board we have the front panel IO and the four USB headers. Also in this area is the Abit µGuru panel connector for those who want to invest in one of the handy gizmo's.

abit ip35 pro pci area abit ip35 pro molex

Being a "Pro" board, Abit have kept three of those usefull PCI slots on the IP35, along with a PCI-e x16 slot and a PCI-e slot running at 4x. A small PCI-e x1 slot is retained for perhaps an abit WiFi module. Here is the only slight grouch I have with the board: the 4 pin molex power connector sits in between the 1st PCI and 2nd PCI-e slot, meaning a slight cabling mess for those who are particularly anal about cabling.

abit ip35 pro cpu area 1 abit ip35 pro cpu area 2

As I have stated before, the CPU area is pretty well free of any obstacle that would get in the way of a big cooler. In fact I even found that my SwiftTech Apogee GT fitted on the board without messing with the PWM cooling, which is something I have had to do on many other so-called "enthusaist" boards. The heatsinks on the IP35 Pro are pretty decent at heat disappation and the caps low enough not to cause much of an obstruction at all.

All in all the layout of the IP35 Pro board was so good I have to compliment Abit on this with not much reserve.

Abit IP35 Pro Intel socket 775 Motherboard Page: 3
Motherboard I/O Backplate

abit ip35 pro io

The backplate IO on the Abit IP35 Pro consists of:

* 4 x USB 2.0 Ports
* 2 x Gigabit LAN Ports
* 2 x e-SATA Ports
* SP-Dif Optical Input and Output
* 7.1 Analogue Surround Sound
* Microphone Input
* PS/2 keyboard and mouse input
* External CMOS reset switch

That's a decent amount of connections, mixing up the old and the new. Remember that the IP35 Pro provides us with 4 onboard USB 2 headers so we'll have plenty of USB input, even without a hub.


The BIOS on the Abit IP35 Pro is a Phoenix Award BIOS and as usual with Abit it has everything you want.

phoenix main page

To get into the overclocking features as usual Abit have gone for their uGuru BIOS utility. This is excellent and allows you full control over what you are overclocking.

uGuru menu uguru fsb

Fron here we see that Abit give you all the way up to 600MHz FSB which is pretty decent.

cpu voltage ddr2 voltage

The CPU volts go up to 1.825v which is rather generous and no-one apart from people using phase-change/LN2 or DICE should be using this much voltage. DDR2 voltage is also generous with 3.0v set in the "DDR2 Voltage" and an allowance for more in "DDR2 Reference voltage". I have not tried this feature as the RAM I was using only takes 2.2v max.

nb 1.5v mch voltage

Again the NorthBridge voltage gets a decent amount of leeway at 2.0v and the MCH voltage gets an allowance of 1.72v.

abit ip35 pro memory timings

Additional controls for memory timing are kept in the "Advanced Chipset Features" part of the BIOS and again there's a generous amount of tweaking to be done here.

Overall the BIOS on the ABit IP35 Pro is excellent as we have come to expect from Abit.

Abit IP35 Pro Intel socket 775 Motherboard Page: 4

Installation was possibly the easiest of any board I have reviewed so far on OC3D. The sheer amount of space created out of nowhere on the IP35 Pro is pretty nice and both my Scythe Infinity and my SwiftTech Apogee GT fitted no problems at all.

abit ip35 pro installed abit ip35 pro installed close

Now here's how I tested.

Test Setup

The following test setup was as following:

Intel Xeon 3070*
Abit IP35 Pro Motherboard
Sapphire X1600 Pro
1gb Mushkin HP2 6400 (4-4-4-10)
Hitachia Deskstar 7K160 SATA HDD
Sony DVD-Rom/CD-RW
Silverstone 560w ZEUS PSU
Silverstone TJ09 case

For comparison I used results from an earlier review by OC3D on the Abit AB9 Review, the AW9D max Review, the Asus P5B-E Plus Review, the abit IN9 32x Max Review and the XFX 650i Ultra Review


To test the motherboard I first ran it at stock using as stress test comprising of Orthos (dual Prime95), Folding @ Home running on both cores (set to idle priority) and RTHDRIBL running 1/2 screen. I let this run for 12hours to see how the board would fare.

The benches and tests used on the motherboard were:

Super PI 1m and 32m

Procsssor Multemedia
Memory Bandwidth
Memory Latency

3DMark05 and 3DMark06 @ 1024 x 768 and 1280 x 1024

Counter Strike Source @ 1024 x 768 and 1280 x 1024

HD Tach


CPU Rendering

Note also that I lived with and used the board for a period of around 2 weeks to check out fully any issues that I found.

As usual there were no problems with installing Windows etc and this all worked out of the box, after simply changing the RAM timings to suit and memory voltage to 2.1v.

* Please note that there has been a change of CPU and although this is basically the same CPU, there may be differences in results.

For the Stability test I ran Orthos which is a dual Prime95 stress test, alongside dual Folding @ Home instances of the console client. To spice this up and really test the board I ran RTHDRIBL alongside this. This is a real test of the boards stability at stock and will show how well it would run in a situation where the board was being stressed to the limit.

abit ip 35 pro passed stress test

The board passed with flying colours..no BIOS update needed and indeed it has coped with absolutely everything I have thrown at it. There is a point when you have a "feeling" about a motherboard and I have to say that the Core2Duo platform has not inspired my confidence, but this board just feels like it will be solid no matter what you do with it. Not since the awesome DFI SLI-DR that I had have I had the pleasure of using such a nice board.

super pi

1 Million

Super PI is 100% the only choice for a quick bench of your top-end rig. It gives a quick and easy estimate of the relative speed of your CPU. The C2D's are now infamous for the their very fast PI times. The IP35 Pro goes up against our previous results here.

super pi benchmark results

The IP35 Pro seems to be a little slow in the race to 1million places of PI.

32 Million

A longer run of the Super PI benchmark shows stability and speed in a quick convenient test.

super pi 32m benchmark

Here the IP35 does pretty well lowering it's time in this longer benchmark.


Memory Bandwidth and Latency

Core architecture has made the Intel platform perform much better than previous generations. SiSoft was always a benchmark that AMD dominated until Core2Duo came out. The IP35 should do pretty well here as we have seen good results from other P35 based boards.

sisoft memory bandwidth

The P35 chipset of the Abit IP35 Pro is showing that it gets some good numbers for memory bandwidth.

sisoft memory latency

Surprisingly the Abit IP35 Pro lags a little behind in the memory latency terms, Abit usually do a good job here and this board is just a little behind the competition.

3DMark05 is a benchmark that relies heavily upon DX 8 and DX 9 shader paths. 3DMark05 is very useful benchmark to give us numbers to compare systems. It does give a decent indicator of gaming performance, and includes a couple of CPU benchmarks. After mixed results in our memory tests, I wonder how the IP35 will do here.

3dmark05 ip35 pro

3DMark06 shows that the Abit IP35 Pro is pretty much up there with the fastest of the boards tested, keeping up with the surprisingly fast XFX 650i Ultra.


3dMark06 is the latest in the benchmarking tests from Futuremark. It has a lot of DirectX 9.0c features such as HDR and use of Shader model 3.0. Will the IP35 repeat the previous resultsin 3DMark05?

3dmark06 results

Again the Abit IP35 Pro shows us that it can get some very nice benchmark figures in the 3DMark test suites.


Counter Strike: Source is a hugely popular online FPS game based on the Source engine by Valve. This will show what a typical gamer will play on their PC and is a great indication of real-world gaming performance as the engine is so scalable. The IP35 pro has done pretty well in the synthetics, but will it do well here?

1024 x 768

css 1024 x 768

Again at the gaming benchmarks the Abit IP35 Pro sticks it with the best.

abit ip35 pro css 1280 x 1024

Not toppling the IN9 32x Max, the Abit IP35 Pro scores well in all of the gaming benchmarks, proving it to be a good solid motherboard for gaming purposes.

All in all the results in this section are very good.

CPU Rendering

Cinebench is a benchmarking tool based on the powerful 3D software Cinema 4D. Consequently, the results of tests conducted using Cinebench carry significant weight when analysing a computer’s performance in everyday use.

cinebench tests cpu

Here the IP35 drops off the pace a little compared to our fastest results. However, it still maintains some decent scores. The IP35 Pro is coloured white on the graph. As you can see it's single cored performance is a little above it's dual core performance.

Cinebench Graphics Benchmark (OpenGL)

Cinebench's test of OpenGL rendering is taxing on even the fastest systems.

sinebench gpu

As we come on to the Cinebench GPU tests using hardware (left) and software (right), we can see that the Abit IP35 Pro does well putting out some nice numbers here competing with the fastest boards in the tests.

Overclocking was performed through the BIOS, as all good 24/7 overclocking should be done. The IP35 is solid and stable and has some excellent options there so I was holding out for some good clocks.

Note here that I am using the Xeon 3070 and that overclocking is significantly easier with this CPU than my E6700ES. I am expecting the board and CPU to put up some high numbers.

Low Voltage Overclocking

I usually start off by overclocking using low voltages. As the Xeon 3070 I am using is so good I will start with 1.35v set in the BIOS. With the control you have over the board in the Phoenix Award BIOS the abit was easy to overclock and at this low voltage the Xeon managed a more than healthy 3.6GHz.



Can't complain at that, although remember that the Xeon is a very good overclocker.

Overclocking - Highest Possible Stable on Air

With this test I took the volts up to as high as I felt comfortable with to see what I could get.


4000MHz stable

I attained 4000MHz (4GHz) dual prime stable on air after some tweaking at a voltage of 1.6v. This is very impressive results but again remember that the Xeon is an awesome overclocker.


For this test I simply tried to get the highest front side bus speed I could on the board, booting into windows. This is not a test of stability, just how high I can boot into windows and take a screenshot.



I think that an upgrade in the cooling on the NorthBridge would lead to even better results than this, but 520 FSB is excellent for a board on stock cooling with no tweaks or mods.

The Abit IP35 Pro was incredibly easy to overclock with a huge range of voltage selections and excellent bad overclock recovery. If you're looking for a board to get a nice high stable overclock I would thoroughly recommend it.

As usual Abit have done a sterling job bringing a board out with the P35 chipset. The board is one of the best laid out boards I've seen with very little to fault it and even the heatpipe cooling solution does the job admirably.

Overclocking and stability are the boards areas of expertise. The board is incredibly stable and I feel confident that Abit are onto a winner with this one. Overclocking is excellent, due mainly to the boards solid stability. 520FSB is a very good figure for a board with stock cooling and no volt-mods. I would not hesitate to recommend this board to anyone who is looking to build an Intel based PC right now.

Priced at around £116 from our recommended retailers below, the IP35 Pro also represents great value for money for such a great bundle of features.

recommended - tekheads Komplett

The only things that may hold you back are the lack of a proper multi-GPU platform, and lack of DDR3 support may also put you off. Having said that, with multi-GPU being somewhat of a waste of money, and DDR3 very expensive right now these are things you may overlook.

The Abit IP35 Pro get's an "Editors Choice" Award as well as "Value For Money" - a top motherboard at a great price.

Editors Choice Award Value For $$ Award

The Good

+ Class-leading stability
+ Great overclocking
+ Excellent layout
+ Good gaming performance

The Mediocre

* Decent general performance
* Decent bundle
* Nice looks

The Bad

- Lack of multi-GPU support
- No DDR3 support
