ABIT NV8 the Sempron’s Best Friend

ABIT NV8 Intro

The ABIT brand of motherboards is very well-known for massive overclockability. And as

they are aimed squarely at the middle to high end DIY market, they naturally don’t come

cheap. The market, however, needs products from all segments, starting from affordable

entry-level to pricey feature-rich high-end. For more price-sensitive users, there are also high

price-performance items such as this ABIT NV8 motherboard.

Found at Newegg.com at a price below $80, this Abit motherboard represents an immense

value as we don't detect any discounts in functionality or quality. And that makes it the

Socket 754 processor’s best friend and really good news for users who are currently

contemplating building a Sempron (Socket 754) system. These users want price and

respectable levels of performance, and this motherboard has got both.

As we already know, there isn’t really an obvious performance gap between the Socket 754

and Socket 939 Athlon 64 processors. This motherboard can therefore be used to erect a

high-performance Athlon 64 computing platform. As such, it isn’t entirely fair to call the

Socket 754 a low-mid-range choice. With ABIT’s industry-leading overclocking technologies,

this motherboard can therefore be used to erect a high-performance Athlon 64 computing

platform.

The above is an officially-supplied shot of the NV8 motherboard.

This motherboard is packed for the price. It comes with 4 SATA data cables and a USB

expansion bracket (with two USB ports). It doesn't get much better than this for the asking

price.

Specifications

Like many other nForce4-4x motherboards, the Socket 754 ABIT NV8 motherboard supports

the Socket 754 Athlon 64 and Sempron processors. As we see in the image above, this

motherboard is designed to take into account the majority of requirements out there. This

motherboard has seven expansion slots (1 PCI Express x16 graphics card slot, 3 PCI Express

x1 and three PCI slots) and 4 SATA ports with RAID support as well as 2 PATA pots.

ABIT NV8 Specifications

Chipset nForce4-4x

CPU support AMD Athlon 64/Sempron (Socket 754)

HyperTransport: 800MHz

Memory support DIMMx2

Single channel DDR400

Graphics interface 1 PCI Express x16 slot

IDE Ultra ATA/133x2

SATA x4（RAID 0/1/0+1）

LAN nForce4 built-in Gigabyte MAC with external Vitesse PHY

Sound Onboard Realtek ALC850 7.1 channel Codec

Expansion slots (non

graphics) 3 x PCI Express x1

3 x PCI

USB USB2.0 x10 (6 motherboard headers)

Close Ups: Rear IO Panel, SATA Port. Expansion Slots

Being a non-high-end product, the NV8 is surprisingly well-equipped with a RJ45 Gigabit

Ethernet port and FireWire, though it doesn't provide dual Gigabit Ethernet ports. The rear IO

panel is at once both feature-rich and practical with the indispensable PS/2 and USB ports,

plus 7.1 channel audio output ports and an S/PDIF output port.

The motherboard’s jumpers use the convenient classic ABIT lengthened design. In addition,

the chipset cooler is molded from copper, which is excellent news for any member of the

nForce4 family which often produce considerable heat.

ABIT provides an auxiliary power connector for the PCI Express x16 graphics cards. The

sheer number of expansion slots on the NV8 is really quite rare among entry to mid-range

motherboards. There are three PCI x1 slots and three PCI slots in addition to the graphics

card slot.

Close Ups: MCP and Onboard Devices

As we are quite aware of by now, many of the earlier nForce4-4x MCPs were actually “A2

edition” nForce4 products that were unable to work stably at 1GHz HT bus speed. This caused

engineers to retard HT to 800MHz. The A2 were limited in number, and ours is actually the A3

edition nForce4 MCP that is able to operate at 1GHz HT bus speed.

CPU-Z v1.30 also detects the A3 edition MCP

Vitesse VSC8201 Gigabit Ethernet PHY Realtek ALC850 AC'97 Codec

This motherboard’s Gigabit Ethernet ports are provided courtesy of the nForce4-4x’s integrated

MAC controller and the Vitesse VSC8201 PHY. This combination is used to provide full-duplex

Gigabit Ethernet, and support for the NVIDIA firewall feature (the standard nForce4 and the -4x

edition do not have the hardware security engine). Overall This motherboard has very strong

networking features. ALC850 is adopted as the audio codec, which is very common among

nForce4 motherboards. ABIT doesn’t used lower grade ALC650 chip.

Close Ups: CPU power supply area and PCB tin stripes

The NV8’s CPU power supply is quite lavishly made with solid aluminum capacitors and

MOSFET heatspeaders– something found rarely on bargain price motherboards.

The above is a shot with the MOSFET heatspeaders removed. This 3-phase design uses 6

MOSFETs in all. Though each MOSFET will operate hotter, they can rely on the heatspeaders

for added heat dissipation.

The NV8 uses only Japanese made capacitors, and most of them come from Rubycon.

Praiseworthy indeed for such a humbly-priced product.

At the back of the motherboard are tin stripes used to aid cooling of the PCB. This a quite

popular design today, and it definitely helps.
