After the official release of Intel Conroe CPU in the end of July,
most of Conroe supported M/Bs are equipped with Intel 965/975 chipsets,
price range from 130 ~ 300 US dollars, depends on its market segment.



Although in general speaking, Intel chipsets have sound performance.
Before the Intel 945 chipset will be released and supported Conroe CPU,
This DFI 662-TMG/G comes with SIS 662 chipset and 85 U.S. dollars of the
competitive price will certainly draw some attention in the retail market.





Product package
Not DFI Infinity or LanParty middle to higher range of product line.
It is a general entry level product.

The lower left hand corner:
South bridge is SIS 966, built-in with four SATA ports
and integrated with RAID 0, RAID 1 and JBOD functions.
Just a pity this M/B does not support SATA II, but is still equipped with two
IDE channels.

The upper right hand corner
Two single channel DRAM slots, support DDRII 533/667

The test in this review was conducted with Intel highest range Conroe X6800
CPU, people asked the reason to use such high-end CPU, our reasons are:
1.Currently we do not have extra budget to purchase an extra middle to
lower range CPU for the review of low budget M/Bs, and this CPU is the only
one came across at the time of our review.
2.This review was done with this Conroe highest range X6800 CPU also
proved this SIS 662 entry level M/B is capable of using Conroe high
performance CPU.

Basic performance:
The CPU performance does not drop much on this all in one M/B.
DFI 662-TMG/G
Strength:
1. Low price “Conroe supported” M/B.
2. One PCI-E 16X expansion slot
3. The temperature on Southbridge and Northbridge keep in very acceptable
range during system operation.

Weakness:
1. does not support SATA II
2. There is still plenty of room for the improvement on BIOS Overclock setting.
3. No DVI connector


Front Side Bus could reach 266Mhz stable, with Pentium D 805/PD915 and other Pentium 4 products.
It will be a very economic PC solution to fit with Intel E4300 CPU for general
usage in the future.

The CPU frequency and built-in VGA performance will be on the next review…

X6800 OC 300X11=>3300Mhz
SIS chipset could also reach FSB 300 stable?

DFI 662-TMG/G
Strength:
1. Under 85 U.S. dollars Conroe supported M/B
2. One PCI-E 16X for expansion card
3. Two IDE ATA133 channels
4. The heat generation is very acceptable for Northbridge during normal
system operation.
5. The Voltage/Frequency setting is considered as feature rich for All in one
M/B products.
6. Front Side Bus could reach 300Mhz stable.
7. Well performed on USB high speed data transmission.


Weakness:
1. does not support SATA II
2. No DVI
3. The temperature of Southbridge is slightly higher, suggest to add a heat
sink for better heat absorption.
4. The VGA performance is just enough for daily usage.
5. No dual channel for memory.




After the post of first review, some people think the price is slightly too high,
perhaps it is because the price of SIS 661 M/B was just about 50~60 US
dollars. SIS 662 is a whole new product, even though the improvement is not
so large, it is still quite normal to have higher price in this IT industry.

As we said previously,
it will be a very economic PC solution to fit with Intel E4300 CPU or Pentium D
805/PD915, plus add-on graphics card, this solution will offer outstanding
performance.



Obviously there are still so many improvements SIS could do to refine this
product, and as far as we concern, focus on All-in-one market segment will
not be a cure for its long term survival.
