Abit IN9 32x Max Intel Socket 775 Motherboard

I/O, BIOS and Specification

IO Connectors

The backplate IO on the abit IN9 32x Max looks pretty complete for a modern board standards.

* PS/2 mouse and keyboard ports
* SP-Dif Optical Connector
* 5.1 analogue sound outputs
* Dual nVidia Gigabit LAN ports
* 4 x USB 2.0 Ports
* 2 x eSATA ports

There is a very comprehensive feel about the IO panel on the IN9 32x Max.

Coming onto the onboard Audio: it is very good. abit include a high-def 7.1 audio chip supporting DTS and Dolby Digital Live. Notice also that a HDMI motherboard audio header is included on the board. The audio is good quality, although enthusiasts are likely to go for a discrete solution still.

Add to this the "EZ CMOS" reset switch and you have a very complete backplate lineup, worthy of a top end board like this.


The BIOS on the abit IN9 32x Max is very comprehensive in it's options. The enthusiast is certainly catered for 100% with a plethora of FSB, memory and voltage adjustment. It is based on the Phoenix Award BIOS.

As the BIOS is so comprehensive I will give a brief rundown of what's on offer as far as extra BIOS features.

Memory Timings

The memory timings on offer are pretty decent. With the normal 4 timings easily changeable, abit have added a couple of extras:

As ou can see: setting manual means that you can set tCL (CAS), tRCD, tRP and tRAS as well as setting 1T or 2T for the Command Per Clock. There's a big performance boost in 1T so I would recommend using this if you can. The tRRD, tRC, tWR, tWTR and tREF are also changeable.

Overclocking Adjustments

abit provide a superb range of overclocking adjustments in their µGuru Utility in the BIOS.

The option to link or unlink the CPU and the memory is excellent, although they do not seem to be totally independent of each other.

The option to set the Multiplier is there as standard in the BIOS and goes up a 3000MHz (quad pumped), 750 actual. I found this a bit of a pain as you have to divide it by 4 to get the actual FSB which then gets multiplied by the multiplier. However 750MHz FSB is something I haven't seen yet on any forum (I'm never one to say it will never happen).

The PCI clocks can be set separately from each other which is a great option allowing for more control over your system.

Voltage Adjustment

Almost the most important bit of an overclockers BIOS, voltage adjustment is crucial on how far a board can go.

Showing this screen on it's own is a must I feel...1.85v on the CPU is for those of us crazy enough to have some serious cooling.

3v+ on the RAM is plenty to play with and adjusting the CPU VTT and SB voltage has some good adjustments too. I though abit could have given the NorthBridge voltages a little bit more as 1.6 won't be enough for extreme overclocks.

EQ and temperature monitoring

abit's µGuru provides nice temperature and voltage monitoring monitoring in the BIOS, although I am not keen on the abit µGuru panel in windows which actually read approximately 5-7°C lower than CoreTemp did (a program hailed by overclockers as the best software temperature program).

That aside there is plenty of fan adjustment to be done in the BIOS and will keep you happy should you want your fans throttle in the BIOS.

It's also worth noting that the blue flashing lights that light up the area beneath the board can also be changed in the BIOS, allowing 5 settings and off...which is nice if it annoys you.

Great review Kemp, nice bunch of packaging akin to the rocketboy type of stuffz. I do wish the µguru thing was more of a 5.25 bay thingy tbh. Last time I checked, retailers were ramming these devices down peoples throats for like £11 or so - which amazes me why u never had one in the box ?!?

I would hope these good results will boost a tad more after some bios revisions, board to board I`d expect this one to be a bit better than shown - but meh..

Kewl, I recognize some of those photos too Quote

Excellent review as usual mate. The 680i's are toasty little sods for sure, and it's a pity that abit didn't even provide some form of active cooling to try and address the problem. Well done Quote

Their answer, and a few other manufs answer, seems to be to add this ugly looking heatpipe structure to stuff.

Heatpipes are great, but I don`t personally like the idea of 2 or 3 of the hs being connected together.Quote

2 or 3 connected together is fine, but that needs active cooling to work okQuote

Great review, Kemp, thanks for doing it as I was thinking of grabbing one. Now for my thoughts...

DAMN DAMN DAMN! I think the 680i chipset is good but not the king, would really like to see the 975X (or updated chipset) that can support nVidia's 8800 series gpu's in SLI... and done by ABIT. ABIT boards look great, and with the exception of the EZ PLUG for added graphics power, I like their layouts; not to mention my AW9D was rock-solid, even using an E6600 @ 3.7GHz... my 680i mobo can't touch it, only solid at 3.4GHz or lower.

Like the EZ CMOS as well, no more dip-switch installations! (newer mobos don't have problems like the old mobos after a bad OC, but it's the thought that counts!)

I personally don't see all the fuss over the passive cooling for the NB/SB. My case uses 4 120mm fans on the side of the case, so I get a lot of extra cooling... not to mention the little fan that came with my mobo for the NB, so I don't have a heating problem. I think it works fine, even without the little fan made for the NB; on the other hand, an enthusiast board should give the user the option to remove the passive to add active (fan) cooling solutions. The only thing I wonder about is the need for pipes from SB--NB--PWM... do the pipes really do anything for the cooling?
