Flash upgradeable. Up to 4 IDE devices. AGP supports 1x, 2x 3. Would have been better to see it across both boards however. Apart from that, the board is quite fully featured. No USB2. As it stands, the board supports good peripheral expansion with 6 bit PCI slots for all the add on cards you might add to your system.

Otherwise layout is identical. As always, lets start at the top left and work our way across and down. Starting in the top left area we have the main ATX power connector and the 3-phase power regulation circuitry and components that feed the CPU socket with power and in turn the rest of the board. The 3-phase power solution is said by EPoX to improve stability, especially in high speed situations when overclocked.

They know enthusiasts run their boards out of spec and they know they are famous for boards that do so. So they developed the 3-phase solution for some of their boards to assist the enthusiast when overclocking and also to provide overall stability at stock speeds.

Moving to the right past that circuit and componentry we see the socket itself. The floppy and IDE connectors are placed, ideally for this reviewer at least, on the right hand vertical edge of the board and aligned vertically. Thumbs up to EPoX for that connector placement. The Northbridge is only passively cooled with no noisy fan which is a bonus.

The KT Northbridge seems to run exceptionally cool. Running all the way up to MHz was possible on this board with no other cooling of the bridge required. The heatsink does the job fine and remained cool to the touch at all times, even under load.

Moving down past the passively cooled chip and we encounter very familiar territory. Everything from the AGP slot downwards is where it should be. Installation was simple. The board uses a full 9-hole ATX mount and was an easy drop in replacement for the last board in the test chassis. No issues with installation at all, as it should be. Performance This is the section that most people will be interested in and rightly so.

While the BIOS would tell us we were running asynchrously, none of our benchmarks would show us that was the case. I was a bit hasty in releasing a review of the board where I could see no discernable difference in the two modes since other reviews had shown a difference and a chat with EPoX UK assured me the board did run asynchronous. These are going to show the same numbers that any well sorted Socket A board will show for the same processor, in our case the XP MHz.

Nothing to look at there. Onto the memory benchmark figures from Sandra. Think about it like that and you see why the figures are so close together. The graph just shows the CPU is working properly.

Next up we have Quake3. Given a fast graphics card, you are able to see the effect that memory bandwidth has on the system when you use Quake3. The fast graphics card allows you to remove it as a bottleneck in the system and leave other variables that influence system performance. In the following graph, all that is changed is the memory clock via a reboot.

As you can see, running the memory bus at MHz and giving us the extra bandwidth shows us a slight but measureable performance increase. At identical clocks, KT and hence the test board will be faster than KT Not by much, but measurable. A small but measurable increase in performance from the free memory bandwidth that we gain. Latency on DDR memory subsystems actually increases when you run asynchronous to the front side bus, negating some of the performance, but on the whole performance rises.

Onto Aquamark, our shader-heavy DirectX 8. Like before, a small but appreciable difference in performance is what we are looking for. More performance at stock clocks and our little increase when running asynchronous.

Again, predictably, we get what we expected. Also, our asynchrous runs show the little increase we need to validate the mode. VIA have tweaked the memory controller a little bit more since KTA the KT controller will appear in P4X soon so performance at the same clocks will increase by a small margin. Latency on the memory increases actually negating some of the new bandwidth performance you get.

DDR memory is happiest running at the same clock as the host bus front side bus so that wait states between the two are minimised. That leads us nicely onto a general observation about the platform. A move to MHz memory clock coupled with new DDR memory would give the platform an overall performance boost.

The CPU can use 2. The higher speed offsets some of the latency increase and everything moves a bit faster. Multipliers can be lowered and given a proper process shrink, the CPU has some headroom left in it for a while before Hammer hits.

AMD seems to have shot itself in the foot however by not increasing front side bus clock or doing some of the other things to help out a lack of bandwidth like a large on die L2 cache. Speed will increase by multiplier only. KT and in future, KT will give the system some more memory bandwidth as processor speed marches on but is it enough? For ages now, boards from different manufacturers but with the same chipset are often withing a percentage point of each other.

Excellent performance all round from the board, no question. Overclocking I wont dwell on overclocking for long except to prove the effect of overclocking the front side bus and letting the CPU have greater bandwidth.

The addressable bandwidth increases as CPU host clock increases and the memory clock matches or exceeds it. As far as overclocking the board went, large front side bus was easy. Dropping down to 9. People are already taking this board to MHz front side bus without doing anything special.

You have a massive range of voltage options available to you without modification 2. The board enjoys the 3-phase power circuitry to provide stable overclocks.

Stock CPU voltage 1. All completely stable I write this at that speed, on this board, as you read! Not a blue screen throughout testing, no instability unless at the very ragged edge and pushing it to the extreme.

A notch below the physical limits of the rest of the system and things were outstandingly stable, something EPoX have worked hard on. Layout is sensible despite with a couple of niggles that are mostly personal rotated socket and slightly goofy ATX power socket placement. The bundle is unexciting but that lets EPoX keep the cost down, something we all appreciate.

Overall very fast, very stable and just what the overclocking doctor ordered. Be sure to run a recent BIOS! A pleasure to test, the 8K3A is fast and stable. Just how motherboards should be. Related Reading.
