2/13/2004 - Update: My new, 480 watt Thermaltake power supply arrived from NewEgg today. :) I just completed the process of pulling out the old Apollo power supply. After about 15 minutes of work with installing the new power supply, applying new cable ties, etc., I hit the power button and things are singing once again in my system. :) I then went through the process of several shut-downs and power-ups. The ills that plagued my system are now behind me.

- Now, I get to have some fun by going back to the computer dealer who told me my issue was a graphics card - and then charged me $179 for a new Radeon 9600XT board. Also, I paid $45 in diagnosis fees, but I'll be happy to just be able to return the video card and avoid the 20% restocking/return fees.

- Also, below, it was mentioned that when I hit the "reset" button, my system would start up because the drives were already spun up to operating speeds. However, on thing has left a question in my mind. When I was having the initial issues over a week ago, I had the board out of my case. I only installed the video card and one stick of memory. All of my drives were left disconnected and the board still would not post. I have a suspicion that the nForce2 boards really like their power. After all, I was using a motherboard with the Via 266 chipset and the same components along with the same power supply for over the past year. Just the installation of the motherboard threw everything into a tailspin. Finally, for those of you who are debating whether to purchase the Shuttle AN35N Ultra board, I say go for it. However, ensure you have an adequate power supply to handle your upgrade. :)






Well, I've owned this board for one week now and there is a "love-hate" relationship going on. I can appreciate all of the options that Shuttle has provided us with in regards to the settings in the BIOS, but I've had some issues with this board that has made me wonder ...

1) Last Saturday, I purchased this board and installed it.
2) It would not post when using my 2 sticks of Crucial 2100 memory and Radeon 9000 video card.
3) I checked the power supply - it was OK.
4) I then bought an FX5600 video card - again, not post.
5) I then got a 2nd AN35N Ultra board (rev. 1.1 like my current one) and both bios versions of 12/5/2003 on them. Again, no post with the 2nd board.
6) Finally, got the board to post with my Radeon 9000 video card.
7) I returned the 2nd Ultra and the FX5600 card.
8) Things worked smooth for the past 5 days.

Fast forward to today.

1) I make an attempt to install my new Sapphire Radeon 9600 card.
2) Again, the board will not post.
3) Put my Radeon 9000 back in - now, it won't post either.
4) I call the shop where I purchased the motherboard from and also some other parts. He suggested that I bring it in.
5) Tech looks at my system. Says there is a conflict between the mobo and Radeon 9600 video board.
6) I ask for the MSI Nforce2 board. Same thing - no post.
7) Finally, the Shuttle posts when they install a new ATI Radeon 9600 board - in their shop.
8) I get the system home - appears to have trouble posting.
9) After hitting the reset button about 3 times, it finally posts - and here I am.


Some things I've thought about -

1) Going back a version or 2 with the BIOS and check if it will recognize my Sapphire Radeon card.
2) Maybe this Crucial memory isn't doing so good with my system?
3) Maybe the CPU is starting to flake out?

It really seems kind of odd that I've had so many issues with 3 AGP video boards on this motherboard. I really want to keep the Shuttle board in my system, because I've had quite good success with them. Any ideas?

Thanks!! :)

my money says your board(s) are fine. id take a look at your memory and PSU.

i have used that board in 3 builds, 0 problems. just thought i might add that...

Yeah, what PSU is towing the trailer there? My AN35N Ultra ran fine with 2 x 256MB Crucial PC2100 and is currently zooming along with an 1800+ Tbred at 9.0 x 210 on a stick of Corsair XMS PC3200C2. I didn't skimp on the "tow vehicle," it's an Antec TruePower430.

Also, it probably goes without saying :eek: but you do have the secondary ATX12V power plugged in, right?

I'm using an Apollo 300 watt power supply. It's a power supply that has been used very frequently by my computer parts place. However, it could definately be the suspect.

Also, I did apply the ATX12V connector to the slot by the video board.

Ironically, I just thought I'd take a few minutes to plug in the Sapphire 9600 - the system now boots up with that card, too. Unfortunately, It didn't this morning. :(

I guess I'll give it a few days and see where things end up. I do have the Antec case, but pulled the power supply out about a year ago when it ran into some issues with excessive fan noise. But, I do agree that a good power supply is essential and might be the cause for the "hit or miss" issues with the AGP cards.

Thanks :)

The other thing that seems to be getting pretty routine is to bump memory voltage a tad, like 0.1V higher than the memory is built for. Crucial PC2100 calls for 2.5V, make it 2.6V. Corsair XMS 3200C2, I went straight for 2.7V.

My board has been doing well... it took a hellacious beating last night, with peak memory usage hitting almost 1200MB (512MB RAM, the rest virtual memory) during a trueSpace render session. No crashing, even when I provoked it by doing other stuff on the side (dialing up to the Internet, firing up ZoneAlarm, playing Solitaire, etc). Hopefully a different PSU will help yours hit its stride :)

I just submitted my order for the 480 watt Thermaltake power supply from NewEgg. I guess we'll soon see if my issues get fully resolved by the use of the new power supply. I'll be sure to post back here and update this thread before the week is over - once I've received the power supply and installed it.

A common problem with the AN35 is that it really undervolts. So raising your volts is really a good idea. For a good place to ask questions about this mobo go here. They really know thier stuff. And this mobo is REALLY picky with RAM. Wouldn't run with my Kingston HyperX 400 but runs fine with TwinMOS / Winbond

BlackMountainCow,

Thanks for the link to the AMDMB forum. I still have an active ID over there from a few years back. Yeah! :)

I got the "el-cheapo" Kingston valueram (Infenion chips) and my An35N-U runs
fine with it.....Go figure..

Ironically, I did bump the voltage for the memory up a notch (2.6V??). My last 3 boots have been successful.

Finally, I looked a bit more closely at my Apollo 300 watt power supply. 5V and 3.3V rails combined produce 180W of power. Well, at least Apollo had enough "balls" to put the actual wattage on their power supply. But, still bad. :( However, I can't wait for the thermaltake to get here. :)

Oh, for those who are having issues with the motherboard posting, I've found that if I hit my "reset" button when the computer doesn't post right the first time, I am able to get it to successfully post - or, at least that's what I did before I bumped the voltage for the memory. I'll keep my eye on things for the next few days and update this thread.

Yeah, I had LOTS of probs with that board, too, concerning the RAM. So far 8 sticks have gone through it and eventually the TwinMOS/Winbond CH-5 worked fine. IT's a good board, but some ppl (like me) really have had bad luck with the RAMs.

Let's see, two Shuttle boards and one MSI board, two Radeon cards and one Geforce. Same problem with all combinations. This narrows the problem down to RAM, CPU or power supply. You didn't mention the CPU you're using nor the speed you're running the PC2100.

Zap,

CPU: I'm running an Athlon XP 1800+ (not overclocked) which is cooled by an oversized heatsink/fan from SVC.
Memory: Micron/Crucial PC2100 running at stock 266 MHz.
Power supply: Apollo 300 watt (180 watts for the 5V and 3.3V combined)

I have a Thermaltake 480 watt power supply on order which should ship out of NewEgg this evening. :)

One other thing I should also point out. I started having problems again with my system posting after powering it up. However, I'm able to get it to boot when I hit the "reset" button on my computer after it fails to post the first time. With each of these times, the reset button has gotten me up and running. Kind of weird. I just can't wait until the power supply gets here.

Yep... my guess is that you will love this board once your new PSU arrives. The reason it POSTs after hitting the reset is because the drives are already up to speed. Starting the POST sequence on a cold boot while the drive is spinning up will create more of a drain on the PSU than it will on a reset. The moment during and shortly after locked rotor current ( the measured current with the rotor locked and with rated voltage) is hard on any component.

I'm using the board as a personal file server, and while it isn't loaded with a high end video card I do have 3 HD's, a DVDR and 512 of DDR with an XP1800 all tied to an Antec 350. It has been an awesome board so far. Still too new to know how it will hold up in the long run though, but as of right now I am very impressed with the board and what it has to offer, especially for the price.

Please post your results once you get the new PSU installed.

Enjoy your new rig!!!!

Okay, so your power supply has a combined rating of 180W on the 3.3 and 5V rails, what is it rated on the 12V rail? That is the real key for the Nforce 2 chipsets with XP processors, particularly if you are overclocking it at all, or running an "uber" video card. If your system is rated at less than 15A on the 12 Volt rail, I would say that is your problem right there. My AN35N has an Enlight 420W PSU, and the Buffalo PC-3200 ram with winbond CH-5 chips and it is extremely stable and runs great. My bet is that your system will be much better with the new Thermaltake PSU. If it still has stability issues, take a look at your ram. Maybe run memtest 86 to test it. Let us know how it turns out. Another good source of information is
Nforcershq forum for the shuttle boards.

Looks like I was wrong wrong about the hard drive pulling current away from the weak power supply. Still, you have solved the problem at last, and in the end it's the results that matter most. Enjoy your new Shuttle!!!!

I'm having the simialar but not exactly the same problem with the AN35N.

I just got a new (better PS) but was going to try something that was mentioned on another board:

run the MOB out side of the case, attach new PS and all other components. Since I have a veriaty of components (multiple hdrives, cdr, cdrw, dvd, memory sticks etc...), was planning to do a bunch of swapping in and out.

Figure it would save time and effort to just have everything flat out in the open (not hassel with case) until everything is running fine and components are picked out.

Problem: nothing powers up - I think its because the "hardware reset switch" and/ or "ATX soft power on/off" jumpers don't have the case wires connected.

I'm guessing the MOB jumpers are open and the board will not boot ??? If I simply jumper the pins - would that bypass the case on/off switchs ??? Or is that a stupid idea - dont want to damage my new board !

Also, the new powersuppy does nothing when plugged in & switch on (out of the case, hook upto nothing) - not even a hum or either fans spin up - Does this sound normal or does this PS sound like DOA ?

thanks in advance

The case buttons are momentary switches. They are normally open until pressed and then go to a closed state which jump (short) the pins. If you are going to jump them with the board outside the case just make sure you are jumping the right pins.

You say the PSU does nothing even connected to the board? Nothing at all? The switch leads must be properly connected to the board or it won't even grunt. If the board is properly connected and you have the jumpers on right then I would say it is very possible your PS is bad, but double check the switch leads before getting a replacement.
