As you would expect with an nForce design the main ATX connector is a 24-pin item, and MSI has managed to give both it and the four-pin 12V connector plenty of space to make it simple to connect your power supply.
And so we come to the main point of interest; the expansion card slots. At the top is a single x1 PCI Express slot, then a x16 PCI-E graphics slot, and then an AGP 3.0 slot with retention device. Below that are three regular PCI slots. MSI has realised that every PCI Express motherboard will only have two or three PCI slots, and that leaves a fair chunk of system resources free for what it terms an Accelerated Graphics Riser, or AGR. The AGR is effectively identical to an AGP 3.0 slot except that it has a significantly slower connection speed than AGP, so even though MSI has published a list of compatible graphics cards which includes a WinFast 6800GT and ATi Radeon 9700, it’s only part of the story.
We tested the K8N Neo3-F using an Athlon 64 3200+ CPU with 1GB of Corsair PC3200 memory with both PCI Express and AGP versions of the 6600GT on Detonator 71.40 drivers with the core running at 500MHz and the memory at 1GHz. The results were eye-opening, and in Doom3 with no FSAA the PCI-E card scored 69.7fps and the AGR version got 24.6fps. We tried a few test runs with an AGP Ti4600 and it suffered a performance hit of around ten percent compared to an nForce3 native AGP motherboard, so there’s no doubt AGR isn’t as good as AGP.
But that’s not the point.
MSI is using AGR to avoid the awful Intel 915/925X situation where you have to buy a new motherboard, processor, memory and graphics card in one huge, expensive bundle. With the MSI K8N Neo3-F you can buy a new processor and motherboard for about £200 and if you have an old MX440 or similar, you won’t even notice a performance drop. When you have the necessary £150 it’s time for a 6600GT and your upgrade is complete and you have the same performance as a regular nForce4 motherboard. Incidentally, system performance is impressive. We ran SYSmark 2002 and got 286 marks, and in PCMark04 we got 3,554 marks, which is very acceptable for a budget PC.
By any standards this is a budget motherboard that relies on the chipset features, and fortunately, nForce4 is a very good chipset. The MSI K8N Neo3-F however, doesn’t have the hardware Firewall that is included with nForce4 Ultra. The ports on the backplate are a little limited – there’s no Firewire for example – and the Realtek ALC655 audio only has three mini jacks with no option of digital output.
The Phoenix 6 BIOS gives you a decent range of options to adjust memory timings, and the Core Cell Menu also enables you to alter CPU and Hyper Transport timings, as well as memory and chipset voltages.
MSI has come up with a decent budget nForce4 motherboard, but the icing on the cake is its AGR technology, which is a clever idea that will help you delay the move from AGP to PCI Express graphics.
