The Intel 875P/ICH5, aka the Canterwood, was the chipset combo Pentium 4 followers had been waiting for. It not only improved on previous Intel DDR solutions, but its performance meant that enthusiasts no longer had to look at the i850E RDRAM boards as the mecca of P4 performance. With support for advanced features like Hyper-Threading, SATA, AGP8x, Dual Channel memory, and support for 800FSB P4s, the chipset is certainly built with performance and future-proofing in mind.

If there is one knock against the Canterwood, it's the price. Performance doesn't come cheap, and although many will pay for it, not everyone can. The Intel 865 addresses the price issue, though the performance is a little lower than the Intel 875. ABIT did come up with an answer though, and have released a lower priced Canterwood (when compared to their flagship IC7-G Max2 Advance) called the IC7, which is what we'll be reviewing today. It doesn't offer all the hardware features of the more expensive "G", but it does match the performance of its more expensive brother.

An impressive list for sure. For those of you familiar with the IC7-G Max2, you'll notice a lot of similarities, but items such as Gigabit LAN, as well as Silicon Image's SATA RAID. That may bother those of you who want a fully featured board, but in that case, you can pick that version up for about 70$ more.

Packaging and Contents

The IC7 ships in a matte black box, which looks pretty nice, but it isn't nearly as impressive as the internal packaging. This is worth a mention because rather than just piling all the extras on top of the motherboard, everything is placed in separate boxes that actually show some logic to it.

The motherboard rests on the bottom of the package, but on the left, you have a fold-out type box that stores items like the manual, CD media, and a motherboard layout sheet. Basically, ABIT places everything needed to configure the motherboard here.

On the right, we have a standard box that stores the IDE cables (round ones also), a SATA cable, SATA power adapter, and the custom I/O back panel. In this scenario, all the hardware related items to setup are here. Missing is a Parallel-to-Serial converter. It's a shame none was included, but understandably, costs are kept down by its exclusion.

Intel 875P Brief

Before getting into the IC7 itself, we'll talk briefly about the brains behind the Canterwood's brawn. You can grab the specifications from Intel's site, but in short, one of the big features is support for 800FSB CPUs. As enthusiasts know, the Front Side Bus is what really determines the overall system performance. In other words, when you're overclocking, 18x133 (2.4GHz) will not be as fast as 12x200 (2.4GHz). Performance will actually be pretty close though, but Hyper-Threading isn't something that is present in older 2.4GHz P4s, but is so in the P4 "C" CPUs.

The other notable feature of the 875P is Dual Channel DDR400. Your PC3200 ram can now run full bore, and in Dual Channel mode. As we've seen with the nForce 2, this technology can add a significant boost to system performance. Ideally, you'll want to run matched pairs to get the most out of it.

In conjunction with the Intel 875P is the introduction of the ICH5 Southbridge. Some of the supported features are USB2.0, SATA, 10/100 LAN, Intel's Communication Streaming Architecture, and six-channel audio. There are two items that will be of most interest though, and that's Soft SATA RAID support (present only in the ICH5R) and Hyper-Threading. The Integrated Intel RAID Technology is interesting because board manufacturers no longer need to add a 3rd party RAID controller. This should save money (for manufacturer and consumer), and PCB real estate.

We've gone over Hyper-Threading before, but in no small words, it's a free performance boost (well, technically not free, since you have to buy a HT enabled CPU) over older, comparably clocked P4s by optimizing a system's ability to multitask. With proper software and OS support, it enables a single processor to run two separate threads of software simultaneously.

The ABIT IC7

ABIT put a lot of thought into the layout of the IC7, and built it with enthusiasts and case modders in mind. To start, the black PCB is very nice, and it'll look great through a case window. There are four fan headers (five if you include the one used by the Northbridge fan), which is the most I've seen on a motherboard in quite some time.

The CPU socket is setup with the socket key facing the back I/O panel, which is a bit different from what I'm used to where it faces the top of the motherboard (or right side if looking at it with the I/O panel facing away from you). With the socket a little further away, and aligned the way it is, this may solve the problem for smaller cases where large heatsinks have problems fitting with a PSU directly above it. Speaking of which, there is plenty of clearance around the socket, so heatsink installs shouldn't be a problem at all.

Moving to the left, we get a look at a sweet looking Northbridge HSF. The fan is quite large, but the noise is negligible. I am quite confident that the cooling will handle serious overclocking, though after popping it off, I'm not too confident with the thermal pad. In my opinion, if you're going to be pushing this board, you should peel off the pad and use a quality thermal compound.

Next up is the AGP Pro 50 slot. I'm not sure how many of you own these cards, but this is something more important for workstation professionals. The slot is keyed though, so it's pretty much impossible to accidentally mess up your video card installation. Curiously missing though is the AGP card retention clip. You also have five PCI slots, which should be more than enough for most users.

Just below the PCI slots are your SATA and IDE connections. You can see the marked areas where the Silicon Image RAID chip and additional SATA connections would normally be on the higher end board. In anycase, you still have two SATA connections, and two regular IDE connections. What I like about the IDE connections is that they are pointed sideways, away from the board, rather than straight up as they normally are. For neat cable freaks like myself, this will make it easier to hide the cables when setting up your drives. It may not seem apparent, but trust me; it is a lot easier this way.

Moving to the right, the power connection is where we like to see it… away from the CPU socket, and at the edge of the motherboard. The floppy connection is right next to it, and it's too bad they didn't align it like they did the IDE cables. Maybe somebody forgot.

The IC7 supports up to 4GB of ram, though that would be an expensive proposition for those of us working in normal jobs. Dual channel support is available by using two sticks of ram in either slot 1+3 or slot 2+4.

The AUX12V connection is one item that I think could have been better placed. There is enough room to fit the power cable in there, but I think a bit more space would make it easier for people with large hands to connect and disconnect the cable.

Your I/O options are quite extensive, including a Firewire connection, and four USB ports. If that isn't enough, you have extra USB and Firewire connections with the included brackets. You'll notice the LAN connection is blocked off, which is no surprise since there is no onboard LAN support.

Speaking about onboard, pictured above, left to right, are the Intel 875P, the ICH5, and the Realtek ALC650. As mentioned, you will not find a LAN physical layer, nor will you find an onboard RAID device.

As with so many past BIOS implementations, ABIT throws everything in here with the IC7. You do have your usual items like Power Management, PC Health Status, and the PnP/PCI Configurations. Let's look at the areas that will be of most interest to our readers.

The ABIT SoftMenu

To access CPU overclocking options, you'll have to set the CPU Operating Speed to "User Defined". Once that's done, you can adjust the Ext. Clock, N/B Strap, DRAM Ratio, AGP Ratio, Fixed AGP/PCI Freq to your heart's content.

Remember that 99% of you only have access to retail Pentium 4 CPUs, so in that case, these CPUs are multiplier locked so you cannot change that. The FSB is another story, and the IC7 offers plenty of headway, allowing you to go as high as 414FSB. Now, the reality is you'll be hard pressed getting above 250FSB without some great cooling.

The AGP Ratio, Fixed AGP/PCI Freq is handy since overclocking the FSB overclocks everything, which can wreak havoc on your system, so it's a good idea to keep those areas within spec.

You got some good voltage options, which is a must when overclocking. The ability to add some extra juice is sometimes the difference between a constantly crashing setup, or a rock solid PC. You can go as high as 1.925v for the CPU, 2.8v for the memory, and 1.65v for the video.

The only other area of note (they are all important, but for those who like to dabble in the art of voiding their warranty…) is the Advanced Chipset Features. It is here you can adjust your memory timings, and if your ram can handle it, you can really tweak it here.

Overclocking

An ABIT board wouldn't be an ABIT without the ability to overclock like a champ. How was the IC7 then? Considering the multiplier is locked, we did quite well. We've had some good luck in the past with the stock Intel cooler, so for the initial tests, we'll be sticking with that.

Out of the box, the 2.4C runs at 12x200.

Stock Speed

Using WCPUID, we can see the CPU is running along at 2405.75MHz. The next OC we went for was 225FSB, which was done without any problems. Stock voltage remained the same, though to run our Corsair TWINX ram at 1:1, we needed to tone the timings down to 2.5-2-2-7.

The next overclock was 250FSB, and in order to do so, we needed to run the ram at 5:4 (200MHz).

250FSB OC

The system booted fine into Windows, but needed a boost to 1.7v vCore to manage stability. Keep in mind we're still using air cooling, so it was about now that I decided it was time to move to water.

290FSB OC

Using our Swiftech H20-8500, equipped with a couple 68cfm fans blowing trough the radiator, the best OC we managed was 290FSB. It'd be a lie to say we were totally stable though, as every few reboots, the system would not get into Windows, forcing a CMOS reset. At 285FSB, things ran much better. I've seen higher OCs from this setup, so there's a possibility that heat may be an issue here (we were at 58C at 285FSB). The radiator is lacking on the H20-8500, and I'm guessing a larger one would allow us ~300FSB OCs.

Just a quick plug to for hooking us up with the 2.4C used for testing. Bob is a super guy, and tell him VL sent ya and he'll hook you up. Let's get on to testing, shall we?

SiSoftware Sandra 2003

Although a synthetic benchmark, it's a popular one, freely available if you wish to make comparison benchmarks. We will be testing the CPU, MMX, and memory speeds.

CPU Arithmetic Benchmark

CPU Multimedia Benchmark

Well, it should be obvious by now that the ABIT IC7 is happiest when paired with the right CPU. The right CPU in this case is the 800FSB Pentium 4. The P4 2.4B (533FSB) cuts into the Canterwood's performance, though the performance is still slightly ahead of the Chaintech i845PE solution.

Memory Benchmark

With our TWINX running synchronous at 2-3-3-7, the IC7 in Dual Channel mode shows its superiority over Single Channel. In SC mode, the IC7 suffers quite a drop, so if you're looking into the Canterwood, it'd be a good idea to invest in a couple of matching sticks of ram.

PC Mark 2002

CPU scores are close, though at 800FSB, the IC7 paired with the P4 2.4C leads the pack. The memory scores show a larger difference, though it should be noted that the memory was only running at 266MHz (which is the case with the 9EJS1 as well). What we see between the i845PE and 875P is that the Dual Channel performance still makes a difference, even though it isn't running at full flight.

PiFast

A good indicator of CPU/Motherboard performance is version 4.2, by Xavier Gourdon. We used a computation of 10000000 digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory. Note that lower scores are better, and times are in seconds.

Lower is Better

What we can gather here is FSB is king, even if clock speeds are the same. I would imagine most of our readers already know that, but for those who don't, here's the proof. We can also see that the IC7's dual channel memory is helping the 533FSB P4 speed ahead of the single channel i845PE.

TMPGEnc MPEG Encoding

Video editing is a taxing chore, and we'll be testing the IC7 using TMPGEnc 2.512 to encode a 7.78MB, 1:30 movie trailer to a 23FPS MPG file. Note that lower scores are better.

Lower is Better

Much like PiFast, the faster FSB and dual channel memory is what you're going to want if you play around with video editing.
