I am never an early adopter of new tech...usually wait until things have been tested out a bit but my hand was forced when my old KT266 exploded two days ago. I had Newegg rush me the new mobo with a T-Bred 1800 and some nice Corsair XMS 2700 Platinum Series RAM. Just to round things out I will comment that the T-Bred came unlocked without the laser bridges cut across L1 and has been a breeze to o/c. The RAM comes with silver RAM-sinks for an extra $1, which looks very nice...don't know what that does for performance though, but it can't hurt.

Northbridge: NForce2 SPP
Southbridge: NForce2 MCP-T

Key added features are the Silicon Image SATA controller, 2 NIC's (one 3COM, one nVidia), 4 USB 2.0 ports and a bracket for an additional 2 USB 1.0, IEEE 1394 - 2 ports via bracket, onboard sound, 5 PCI and 3 DDR slots. Items found on other ASUS boards which are missing here are built-in card reader functions (the VIA boards I know have on-board CF/SD/MS reader capability). Other nice features include the ASUS Q-FAN which will adjust fan speeds according to temp, ASUS POST Reporter which gives voice error messages if you can't POST, and CPU overheat protection with throttling.

The board was very easy to install. There is plenty of room for a big heatsink and the part of the clamp you have to push down on is directed toward the top edge of the board, giving you plenty or room to manipulate a screwdriver (out of the case, that is). The northbridge has an enormous heatsink w/o a fan. The ATX connector is far away from the CPU, north of the IDE connectors, making it easy to stash the power cable behind your drive bays - a very nice touch. The memory slots and arms seemed very well constructed and memory installation was a cinch.

The AWARD/Pheonix BIOS is standard stuff with good overclocking options. FSB up to at least 211 and VCore up to at least 1.85 (I say at least because that's what is listed in the manual and I don't remember off-hand). The usual memory tweaking options. Voltage options for AGP and memory. It automatically adjusts the PCI/AGP dividers based on your FSB setting, but does not inform you what it is anywhere, which is somewhat annoying. The first time I set it to 166 i just had to cross my fingers and hope it was going to adjust the dividers appropriately. For System and Memory it gives you three standard options: Aggressive, Optimal, and User Define. I could see no difference between the memory settings it chose with Aggressive and Optimal though. I just set everything to Aggressive. This did not seem to affect benchmarks.

The included software has dirivers for USB 2.0, LAN chips, onboard sound, and NForce monitoring utilities. Of those it was all pretty easy except for the USB 2.0. You have to install two sets of drivers in a very specific order. They give you a very ominous warning that if you do it wrong you may permantly screw your Windows and have to reinstall it. They then proceed to give fairly crappy (and in my case, inaccurate) instructions on how to proceed. In my case I found my USB 2.0 hardware hiding in the Device Manager under Other Devices with some generic "Other Device Unrecognized" name. I then had to try to force the driver update on several of these until I found the right one.

At first I fired it up at 133 FSB just to get the kinks out. After running a few benches I noted that there was virtually no performance gain over my previous KT266A setup. I then upped to 166, dropping my CPU multiplier, and everything went off like clockwork. Since then I have continued to stress it in every way possibly...advancing slowly at present. It has not offered so much as a single hiccup throughout the whole process. Just from transition from my old system to the new one with 166 FSB, i got ~ 800-1000 increase in 3DMark. Sandra memory scores at 166 with Aggressive settings are RAM Int:2568, RAM Float: 2401. This compares quite favorably to a KT333 with PC2700 (2092/2014).

Update 11/28/02: System running at 166 FSB with CPU at 1.92@1.60V. Problems with ASUS Probe reporting incorrect temps...reports about 8C cooler than actual temp reported in BIOS. FSB overclocking did not go very well. When locking the AGP at 66, dialing down the cpu to normal speeds, I was only able to get the FSB to 170 before hard-locks started occuring. System remains very stable at 166 FSB though.

Update 12/02/02: Interesting quirk with the board discovered. When overclocking and system locks, the mobo does not reboot on the next attempt - it just gives a no-POST. I found I must reboot twice to get it to POST after a hard-lockup. This initially lead to some elevated sphincter tone moments when I was sure I had destroyed the CPU (which BTW is now up to 2.01@1.725V).

Excellent review, thanx for the info!

options for AGP and memory. It automatically adjusts the PCI/AGP dividers based on your FSB setting, but does not inform you what it is anywhere, which is somewhat annoying.
I believe there is a way to set the AGP bus to whatever value you request according to this review.
OC Workbench writes:

This is probably the first board that implements a FIX AGP selection. You can fix the AGP to run at 66mhz no matter what is your FSB. A maximum of 100Mhz can be chosen.

Oh neato...I'll have to look into that. I did not see any options in the BIOS though.

I got this board about two days ago and this one is also working great!

However I did not have any problems with the usb2.0 installation (could be taht I installed the sp1 first).
The performance is great, and the thing just works!

The audio is also superb. And what a great soundstorm utility!

The system haven't crashed since I got it, and it have been running for 3 days now, running heavy programs almost all the time. (And it haven't been rebooted in over two days).

The rest of the system:
Athlon xp 2000+
Crucial pc2700 256mb
Gainward geforce ti4200
WD 800JB
LG 32/12/40/16 combo

Great motherboard!

halkebul - you were right about the AGP frequency, it is totally configurable in 1 MHz increments...how boss is that? There is also an AUTO setting, which is what I had it at.


Knutp - you are correct. If SP1 is installed then you don't have to mess with the USB 2.0 stuff. I refuse to install it though because I heard too much bad stuff about it.

BTW, correction - the VCore only seems to go up to 1.75 in the BIOS.

You mean they didn't include an all-in-one setup like there was for nForce 1? I wonder if the new nForce version 2 drivers will do it all automatically?

The nForce2 looks to be a lot more interesting than the nForce was. This is especially true since they are releasing them without the onboard video.

The nforce1 also has a version without the on-board video, the 415.

Maybe they should have said 'the first board that allows you to fix the AGP frequency at settings other than 66mhz'. There are earlier boards that have fixed AGP/PCI clocks.

How did your motherboard explode?
Minding my own business, playing UT2003. System had been running fine for over a year. All of a sudden "bzzt" ---> black screen. Upon rebooting an endless loop of long beeps (memory error) and then that lovely smell of burning PCB. One of the memory chips had a nice brown burnt area on the contacts.

Can u please post a pic of the Soundstorm Control Panel?
Sorry man. I'm not using the onboard sound and it won't let you access the Panel if you don't have it installed. Maybe someone else here with the board will do it?

Is there anyone using this motherboard with an Athlon XP2600+ or faster? I am thinking about building using the Asus board with either a 2600+ or 2700+.

Thanks for you time in doing this :)

Let us know what max. FSB you can get to.

this motherboard has become a headache for me overclocking... i can't figure out how i got the higher multipliers before. Early on, i did hit the 16x multiplier and the bios reported a 2600+. it crashed but that was most likely due to the bad HD i was trying to read off of.

anyway, i can't get to that point anymore. i'm going to look for a window defogger kit and i'll see if i can't unlock it and at least get a 2ghz@166fsb (there doesn't seem to be a way to get 13-14.5x multipliers unfortunately).


Other than that, i run 40-46 load (sk7+92mm zalman w/ resistor) depending on whether or not the room heater is on :) One interesting feature if the cpu fan speed control. I think it basically lets you do what the zalman resistor is doing. I will be trying it out later.

what about the PCI bus? can it be locked? I heard from epox representive (aoaforums) that nforce2 only has agp lock but no PCI lock because of some limitations. AGP lock and PCI lock only exist in p4 mobo but for nforce2 only agp lock. Is that true???

It seems to be true. I could find no way to adjust the PCI clock on this mobo.

This board automatically adjusts the PCI bus frequency based on the FSB - automatic PCI divider. No matter how high one sets the FSB, the PCI bus never exceeds 34 mhz.

LMK how high to get that CPU. That is most likely the one I am going to get since a few people have been able to get 2Ghz with it. LMK how high you can get. Thanks

Why a way to adjust the AGP bus but not the PCI? Modern graphic cards can take pretty high AGP bus speeds but it is the PCI cards and HD (that ride the PCI bus) that have trouble with high PCI bus speeds. Could it be because Nvidia is a graphic card company and so they centered there work on that? Or if you set the AGP at 66 is the PCI also locked at 33, as the AGP bus is always double the PCI bus?

It'll probably be a little while before i push this proc to its max. I am taking a while to test it out between bumps just to be certain.

how can I check the PCI bus ?? I don't think sandra can show the correct result.

You are correct. Si Soft doesnt support the nForce2 chipset due to a lack of documentation/datasheets. Some have accurately gauged the PCI bus frequency using the PC Geiger device.

Anyone running an Alpha 8045 HS on this board? Does it have the four mounting holes and is there room?
