Introduction


Abit is a company that enthusiasts should definitely recognize.  Abit has been known for their excellent overclocking motherboards since the ancient days of Pentium IIs and Celerons.  Their Socket A KT7 motherboard, based on VIA's KT133 chipset, was considered the motherboard closest to perfection.  They continued the trend with the KT7A, KR7A, KX7, and so forth.  Boy, those were the days.  Many argue about the quality of their NF7 series of motherboards.  It went through a total of 4 revisions to fix major bugs and problems.  Some argue that Abit lacked ability in fine tuning a motherboard, while others argue that Abit listens to what the overclockers demand.  Nonetheless, the NF7 v2.0 is a great board, perhaps the best Socket A motherboard, if you know what you're doing. 

As AMD introduced the Athlon64, Abit introduced their first Socket 754 motherboard.  The first one, version 1.0, came with one huge bug--no AGP/PCI locks.  Everyone looked down on Abit for not providing working AGP/PCI locks and turned away for quite some time.  Fortunately, Abit was quick with their revisions and came up with the current version--v1.1.  It provides working AGP/PCI locks to allow for potentially great overclocking results.  While many consider Socket 754 an aging socket, it should still stick around for a while.  Heck, Socket A is still around, so why not Socket 754? 

 


 

Abit KV8 Pro v1.1 Package

The KV8 Pro comes in Abit's signature orange/red PCB.  This color usage started with the NF7 series and continues on for both AMD and Intel systems.  The bundle in the KV8 Pro is rather light.  Although rounded cables are way better than flat cables, there is only one included for IDE.  There's the usual floppy cable (also rounded), a user's manual, quick installation guide, drivers CD, floppy of RAID drivers, I/O plate, and two SATA cables.  There's nothing fancy about the bundle; It's meant to be a budget board for the budget enthusiast. 

 


 

Motherboard Layout

The KV8 Pro utilizes VIA's K8T800 Pro chipset.  Unlike Nvidia's nForce3 offerings, the K8T800 Pro continues the use of both the Northbridge and the Southbridge.  Although AMD's Athlon64 CPUs have on-die memory controllers, the use of two separate bridges is still ideal, at least it is to me.  One reason is that it reduces the amount of stress on the bridges.  The Northbridge still handles the usual interaction of graphic card to CPU, but just no longer handles the memory interface.  This can really help with cooling.  The less load on a chipset, the less heat it produces.  The VT8237 Southbridge still acts the same and is the controller of your normal drives, audio, USB connections, PCI buses, and other extra goodies.  The placement of these two separate bridges also allows for better cooling alternatives.  Like I mentioned in the DFI LANParty UT nF3 250Gb review, Nvidia's placement of their nForce3 chipset just plain sucks.  It doesn't mean that I don't like Nvidia's chipset, I just don't like the placement.  With VIA's solution, you can find better cooling for the Northbridge; but that's not really needed, as the passive heatsink is already sufficient.  Both the Northbridge and Southbridge ran perfectly fine during load tests and didn't cause any heat issues whatsoever.  The passive heatsink was barely warm to the touch.

The location of the IDE ports are located at the bottom right corner, where most hard drives reside at.  One IDE port should sit at the upper half of the motherboard, though, because that's where the usual optical drives are located.  If you happen to install this board in a larger full tower, you might run into troubles if your cables aren't long enough.  What I like about the IDE ports is that it faces a 0° angle, instead of the usual 90° angle.  This allows the cables to be folded and tucked away more easily.  The SATA ports are located right next to the IDE ports, and are controlled by VIA's VT8237 Southbridge.  Abit provides 2 IDE ports and 2 SATA ports for a total of 6 possible drives.  The SATA ports allow RAID 0, RAID 1, or JBOD.  The floppy port is located right above the ATX connector.  These two should be switched around; but their positions are still tolerable.  Notice in the picture that there are only two DIMM slots.  When I first saw it, I was very disappointed.  Although most users will only use 2 DIMMs for a total of 1GB system memory, Abit shouldn't stray away from the norm of 3 slots.  The extra slot might come in handy when using the OCZ Booster or just adding another stick of RAM. 

The KV8 Pro comes with 5 PCI slots and 1 AGP slot.  I always wonder why companies supply so many PCI slots when onboard features are becoming so plentiful.  But still, there are plenty of PCI slots for your extra peripherals.  The AGP slot comes with the usual locking device that we all come to favor.  Unlike the hideous lock on the DFI, the KV8 Pro's AGP lock allows easy installation and removal of graphic cards.  To the right of the PCI slots are the usual two USB headers for more USB ports.  The position of these headers is not very ideal, but only applies to those who actually makes use of these PCI slots.  The cables to the USB headers can get in the way of add-on cards.  One extremely annoying placement was the CMOS jumper.  It's located directly next to the AGP slot.  Ideally you would want the CMOS jumper to be at the bottom of the motherboard, far away from components that might get in your way of access.  Enthusiasts will definitely get annoyed when playing with overclocks on this motherboard, especially if you're working inside a case.  It was no problem for me only because my test bench was in an open environment and I was able to access the jumper from various angles.  The space between the DIMM slots and the AGP slot is ample and doesn't require removal of graphic cards to install or remove RAM.

 


 

Motherboard Layout Continued

At the back I/O, the KV8 Pro provides the usual PS2 keyboard and mouse ports, 1 serial, 1 parallel, 4 USB, 1 Ethernet, audio in and out jacks, and 1 optical in with 1 optical out.  The onboard sound solution is controlled by Realtek's ALC658.  Since this is considered to be a budget motherboard, the 6-channel sound solution is good enough for the mass majority.  Audiophiles will probably look for something better, but I found that the onboard sound was good enough for my typical music listening and games.  The broadband connection is controlled by VIA's own VT6122. 

The front I/O connectors are at the bottom right corner of the motherboard.  If you look closely enough, there are markings for proper connections.  You won't really need to refer to the user's manual.  Next to the front I/O connections are the diagnostic LED's.  While some find them rather useless, I tend to like diagnostic LED's for the sake of simplicity.  It does help to figure out what went wrong when there is a no POST.  It also helps with the overclocking process.  If the codes don't change, you know that the system failed to boot.  Be sure to keep in mind that your power supply needs to have a -5v rail in order for the diagnostic LEDs to work.  Above the front I/O is Abit's signature uGuru chip.  uGuru is Abit's in-Windows software overclocking utility that provides enthusiasts the ease of tweaking the system without having to go through BIOS and restarts all the time.  I'll cover more of this later on.

The CPU socket area around the KV8 Pro is rather cluttered, but using aftermarket cooling solutions should have no problems.  One thing is that because the motherboard is smaller than the standard full ATX size, the DIMM slots are closer to the CPU socket area.  This means that if you plan on using large heatsinks, like the Zalman CNPS7700 series or even Thermalright XP series, you'll probably want to install the memory before installing the heatsink.  Removing the memory will probably require removal of the heatsink first.  The CPU fan header is located right above the DIMM slots and is well within range of the CPU socket.  Although the board is meant as a budget motherboard and comes in a smaller size, the KV8 Pro provides enthusiasts a whopping total of 5 fan headers.

 


 

BIOS

One of the main reasons why Abit became so successful was signature SoftMenu overclocking section of the BIOS.  All the adjustments you need for overclocking are located under one area so you won't have to go through different sections just to find voltage options.  In the case of motherboards that feature Abit's uGuru, that section is called the uGuru Utility.  Inside, you have the options of HTT frequency, CPU multiplier, AGP bus, and all the typical voltage settings.

  • All voltage settings run at default when AUTO DETECT is enabled
  • VCore:  1.5v-1.85v
  • VDIMM:  2.5v-2.8v
  • VAGP:  1.5v-1.65v
  • NB Voltage:  1.5v-1.65v
  • SB Voltage:  2.5v-2.65v
  • HyperTransport Voltage:  1.2v-1.4v
  • HTT Frequency:  200-410
  • AGP Ratio:  Fixed 66MHZ, 1/6 divider, 1/7 divider, 1/8 divider
  • CPU Multiplier:  5x-highest your CPU allows
  • LDT Multiplier:  1x-5x

The KV8 Pro BIOS comes with some great voltage options and memory adjustments.  Although not as rich as the DFI LANParty UT nF3 250Gb, the KV8 Pro also provides extra memory settings than the typical CAS, TRCD, TRP, TRAS.  While the VDIMM may seem a little lacking to some, it is actually enough for the popular TCCD based memory.  If you own a pair of BH5 or UTT, you'll be happy to know that uGuru supplies up to 3.2v.  More will be explained on uGuru later.

Notice in the image below that the default clock on the KV8 Pro comes at 204HTT.  This is commonly found in current Abit motherboards.  Companies often do these little things to show that they have higher performance.  It's a bit of "cheating".  I manually adjusted the clock to run at 200HTT just like all other boards tested for comparison.



 

Software

The software bundle of the KV8 Pro is relatively light, because there are no extra programs included.  All the necessary drivers are included on one drivers disc.  However, it does come with the great program: uGuru.  As mentioned before, Abit's uGuru program is a Windows based utility that allows enthusiasts to overclock on the fly.  This means that you can overclock while you work in Windows and don't have to bother with multiple system restarts.  If the system crashed because you overclocked too high, the system will restart and restore to your last BIOS settings. 

uGuru doesn't come with just the overclocking feature, it also comes with Abit's FlashMenu, BlackBox, and Abit EQ.  The FlashMenu is a Windows based utility to update your motherboard to the latest BIOS.  While I tend to stay away from Windows based programs for BIOS updates and prefer the traditional DOS method, the FlashMenu can come in handy at times when you want to "force/trick" the system into using a beta BIOS.  The BlackBox feature is used for technical support.  If you have problems with your system, simply run BlackBox to detect your hardware information and then send it in to Abit.  And within 24 hours, Abit will get back to you and try to figure out your problems.  The Abit EQ is Abit's hardware monitoring utility.  It provides users information on voltage lines, temperatures, and fan RPMs. 

 

 

 

Now we get to the fun utility--Abit's OC Guru.  The OC Guru is the one most enthusiasts will mess with.  It allows users access to SoftMenu and overclock from there.  There is a slider for the HTT frequency and a slider for the AGP bus.  Unfortunately, I was unable to move the AGP bus.  Through the OC Guru, it seems that the AGP bus isn't locked.  It would change if I increased the HTT.  The most wonderful thing about the OC Guru is that it allowed higher VDIMM options.  Through the BIOS, users were given a maximum of 2.8v.  Through the OC Guru, users had access to a high of 3.2v.  This is certainly good news for enthusiasts who still own voltage hungry memory.



 

Test Setup and Overclocking

Test Setup:

  • AMD Athlon64 3000+ Newcastle
  • Abit KV8 Pro v1.1
  • DFI LANParty UT nF3 250Gb
  • Asus K8N-E
  • 2 x 512MB Centon Low Latency PC3200 2-2-2-5
  • ATI Radeon X800 Pro
  • Nvidia unified platform drivers 5.10
  • VIA Hyperion v455
  • ATI Catalyst 5.1
  • Hitachi 80GB SATA

Overclocking:

Overclocking the KV8 Pro was a dream.  Like the DFI LANParty UT nF3 250Gb, the KV8 Pro provided some impressive results.  I proceeded to find the highest HTT allowed with both single and dual sticks of memory installed.  The first test will be conducted with the memory divider at 1:1.  The second test will be with a divider, so that the RAM wouldn't pose as a bottleneck.  All memory timings were left at 3-4-4-8 2T and the LDT multiplier at 1x.  I made sure that nothing would bottleneck the chipset potential.  The reason why I tested with two sticks of memory is that most systems today makes good use of 1GB or more.  Running 512MB can get a little slow at times, especially during game loads. 

  • Highest overclock 1:1 single stick:  290HTT
  • Highest overclock 1:1 dual stick:  255HTT
  • Highest overclock with divider single stick:  315HTT
  • Highest overclock with divider dual stick:  315HTT

The results are definitely impressive to say the least.  Although the results weren't as high as the DFI, it's still very close.  Socket 754 is known not to be very overclocking friendly when two sticks of memory are installed.  You do get some great results when running a divider though.  Since this is considered to be a budget board, you'll probably end up using one stick of RAM.  If so, you'll definitely be able to go somewhere if you spend some time familiarizing with the board. 

 

 

 

Results

During testing, all HTT are manually set to 200MHZ.  Command rate was set at 1T and only the normal CAS, TRCD, TRP, TRAS were adjusted to 2-2-2-5. 

Sysmark 2004

Sysmark2004 is a very common benchmark used to measure a system's potential in performance.  It goes through long, grueling tests that include compression, decompression, and office intensive programs.

3DMark2001SE

3DMark is probably the overclocker's favorite benchmark.  Unlike 3DMark2003, which stresses mainly the video card, 3DMark2001SE tests all of the system's main components.  Increasing the CPU speed, memory speed, and video card speeds will result in higher results in the final score.  Although not quite as fast as the K8N-E, the KV8 Pro still scores higher than the DFI.  This is due to the fact that the DFI needs much more memory tweaking in order to keep up.

PCMark2004

The PCMark2004 system benchmark puts the entire system to work.  The KV8 Pro only scored just a little higher than the DFI.

PCMark2002

PCMark2002 is older than PCMark2004 but still very similar.  Once again, the DFI scores are lower, especially the memory bandwidth.  The KV8 Pro scored higher but is still behind the K8N-E. 

 


 

Results Continued

Everest Home Edition

Everest Home Edition is a good benchmark for testing memory performance.  Since the motherboard's overclocking potential and memory bandwidth is closely related, I find this benchmark to be trustable.

SiSoft Sandra

Like Everest Home Edition, SiSoft Sandra memory bandwidth tests the motherboard's memory bandwidth performance.

Super PI

Since the value of PI is an infinite value, Super PI is a speed test to find the digit you're looking for.  In this case, we chose the millionth digit.  Super PI benefits greatly from higher FSB as well as low latencies.

PiFast

PiFast is similar to Super PI and the results can be greatly affected by a slight adjustment to the memory megahertz and latency. 

Unreal Tournament 2004

Unreal Tournament 2004 is a very popular game that is highly effected by the system's performance.  Testing was done under the resolution of 640x480 to minimize the dependency of GPU and CPU power.

 


 

Conclusion and Thoughts

Abit's budget solution for the Socket 754 is indeed a decent success.  Although the performance is not outstanding, it's still somewhat better than the acclaimed DFI.  The use of VIA's chipset may or may not be ideal, due to VIA's bad history of chipset drivers, but Abit's implementation is well done.  The KV8 Pro overclocked great and comes with abundant features to suit your needs.  The onboard audio isn't top of the line, but gets the job done.  The inclusion of many fan headers is admirable, considering the board is smaller than the full-sized ATX motherboard.  The most impressive part of this motherboard is the price tag.  Coming in at well below $100, the KV8 Pro provides some tough competition.  Because it's so cheap and packs quite some power, the board is a good recommendation. 

Pros:

  • Attractive orange/red PCB
  • Excellent price tag
  • Abit's excellent official support
  • Working AGP locks
  • Decent performance
  • Excellent overclocking potential
  • uGuru utility
  • Good BIOS options
  • Includes 5 fan headers

Cons:

  • Lacking software bundle
  • Only provides 2 DIMM slots
  • Extremely poor location of CMOS jumper
