Mainboard AS40GT, AS45GTR

Pros: Can run memory at 166 MHz (333 MHz DDR), Solid and stable platform, Great expansion capabilities, Outstanding layout, Strong performance across the board, Great features, Shuttle quality

Shuttle who always seems to be at the forefront at present have produced another fine motherboard that is stable and competitive and can not be ignored or overpowered by other manufacturers based on overclocking facilities .The AS40GTR has its own overclocking potential and probably will provide enough for the casual enthusiast, but again its a stable board and has all the benefits of the SiS645 chipset. The layout is almost perfect and with an almost jumper-less free operation it would suit anyone attempting to build a machine whether first time or 100th time.

Once again Shuttle provides us with unbeatable performance, there really wasn’t a test that the AS40GT-R had an out-right lost in. The board delivered extremely impressive memory results in both SiSoft2002 and MemTach. The board’s performance wasn’t all just about the 3D scores and memory transfer rates. There is more to the AS40GT-R such as ATA133 RAID and 6-Channel C-Media. C-Media’s 8738 audio controller deserves more credit that what it’s currently receiving. It’s not a bad audio controller and delivers high quality audio without all the bugs other high-end sound cards are having with Windows XP. The AS40GT-R design has a certain look and feel to it. Everything seems to be perfectly placed and nothing really seems to be crowded. Despite the lack of overclocking options I still really enjoyed testing the AS40GT-R, and wouldn’t hesitate to recommend it because of this missing feature. Overall I came across no bugs or any other issues with the AS40GT-R and best of all the board didn’t crash once whilst overclocking and testing. (...)

...insgesamt war das Board sehr beeindruckend. AV45GTR war 200MB/s
schneller als AV40/R. AV40/R ist das schnellste P4X266 motherboard
überhaupt, und die Steigerung der Speicher-Übertragungsrate bei
AV45GTR um weitere 200MB/s ist extrem eindrucksvoll.

AOpen AX45 versus Shuttle AS40GTR: With any "showdown" there must be a winner and of course a loser. In this case it's pretty clear who the winner is, the Shuttle AS40GTR motherboard. I'm pleased to award the Shuttle AS40GTR our Life Sentence Award for it's excellent layout design, feature list, and performance.

I was very impressed by the attention to detail Shuttle showed in the AS40GTR motherboard. The power headers were all neatly tucked out of the way. The space between the AGP card and DIMM retaining notches is more than adequate. The black plastic AGP retaining lock is a great addition to help prevent problems novice users may have with proper AGP card seating.

The addition of the HighPoint 372 Controller is a great touch. Not only do you get on-board RAID, you also get the ability to upgrade to ATA133 based hard drives. Even with the 2 extra IDE ports the HighPoint 372 brings to the table, Shuttle still managed to find the room needed to properly route your IDE cables. All in all, the layout of the Shuttle AS40GTR is one of the best I have seen.

I was very pleased with the performance and stability of the Shuttle AS40GTR motherboard. Performance was consistent and didn't give any surprises. About the only issue I have with the AS40GTR is it's lack of overclocking features. It would have been nice if Shuttle had included "+ 1 MHz FSB adjustments" and voltage adjustments to the VDIMM.

PROS: All around very good board. 
CONS: None I can find. 
USER COMMENTS: This was the second board i had bought the first the bios kept going out. This board has given no problems and has been very stable. I have had 2 friends go out and buy it because of my experience.
