Recently, the most popular thing in PC market must be Intel Core 2 Duo CPU.

Therefore, the relative motherboards, which support Core 2 Duo series, also
took advantage in this period. On the otherhand, 965 can be easily let FSB
up to 450~500 MHz, then its price (mobo) is only around $130~ 250. If
compare with 965, 975 is lot more expensive than 965.


I also realized something about mobo in OC field:
ASUS is the best mobo manufacturer in Intel platform
Then, DFI is the best in AMD platform.


DFI has launched INFINITY 975X since July. A reasonable price $200
With a bunch of features, such likes: 6 phase digital PWM, ceramic heat sink,
X16 PCIe for Crossfire, e SATA interface and 400~ 450Mhz FSB OC
ability...etc.
It breaks the market positioning of others 975X, also affects the pricing to
some of the 965 mobos.










At that time, I have brought out 2 defect about this board:
1.The compatibility of DDRII still needs to be improved.
2.The boot up screen and OS monitoring software also need to be strengthen.



System info
CPU:INTEL Core 2 Extreme X6800
MB: DFI INFINITY 975X/G
DRAM: Corsair TWIN2X2048-6400C3
VGA:ELSA GLADIAC 790GS 256B3
HD: Seagate 7200.7 80GB
POWER: Corsair HX620W Modular Power Supply
Cooler: Sonic Tower





when I use the previous version BIOS, FSB around 300~400Mhz, What I can
choose is CPU:DRAM 1:1.33 or 1:1. then, the DDRII only can run 800~950
Mhz approximately.

The 9/13 BIOS version, some guys in the forum said that was rearranged by
Oskar Wu....
CPU 374Mhz, Ratio of BIOS~ 1:2>>1:2=>DDRII 1122 CL4 4-4-9 run steady








CPU 389Mhz, Ratio of BIOS~ 1:2=>DDRII 1170 CL4 4-4-9 successfully






The latest version of the BIOS makes the DRAM OC ability increase a lot.
Speak frankly, this model has already far beyond the mid-range image.
The result of DDRII clock can reach above 1100, it's already a highest model
in Intel platform. in price and OC ability, DFI INFINITY 975X is such a great board, no matter compares to same level platform like 975 or 965.

I'd like to expect the LANParty version of 975X has a better and powerful
performance then.

but the 24 pin layout is a little inappropriate might i say..

yup the 24 pin and 4 pin is block by cooler...zzz.....

intel 975 chipset should be high end mobo for most of the brand..but this dfi still using normal heat sink for it chipset cooler while other using heat pipe and fan to cooler it rather than passive

those motherboard with copper heatpipes will only create more heat on the mobo itself unless proper cooling is applied.

from the past i have been using DFI mobo with simple northbridge cooling, none of them hinder my overclocking ability.

- passive heatsink on socket A DFI Infinity
- passive heatsink on socket 754 DFI LANparty
- normal low profile aluminium cooler on socket AM2 Biostar TF550
- normal low profile aluminium cooler on socket AM2 DFI Infinity

i would hv use ths board if the atx power socket is in the normal placement like those other boards

i like it how thread starter always include a small .. dunno , doll ?

when taking photo's during OC and stuff like that
makes it unique

i envy your ability 2 test out these mobos and stuff
but really concise and accurate reviews

btw, siaunn, what power slocket problem/?

i mean the 24pin atx power socket...

Yes both of the power sockets are putting too near already.Not really good placing on the both socket.Any lowtayians here buying this board?

what can i say this is cheaper version of 975 mobo...still use normal cap instead of solid cap...

it's odd that all newer DFI Infinity AMD mobos are locating ATX power connectors at the right side of the motherboard already, but not on Intel's, like this mobo for example.

It uses solid caps around the cpu area if you see properly.
