I am putting togeather a new computer with following components ASUS A7V333 MB Rev 2.0, BIOS 1015, using JumperFree setting AMD Athlon XP 2000+ Crucial Technology CT6464Z335 512MB DDR333 PC2700 Memory ATI All-in-wonder Radeon Western Digital 100GB 8MB HD After assembling when I started for first time BIOS setup asked to set the CPU speed, since I was runnig in JumperFree mode. I set it to 1667MHz. Other parameters are CPU Multiplier 12.5X System/PCI bus 133/33MHz CPU core voltage 1.75V But the system hangs up giving message "During the last boot-up your system hung for an improper CPU speed setting" I have tried falling back to 100MHz system bus speed. But doesn't help either. Called up ASUS and they say the CPU is screwed up. I can't test that statment. It can be borad also? Anyone have any idea?

try to reset the bios defaults, with a jumper or take out the battery for about a half hour. then try to start at 100 bus speed and see if that works.

This is the very same thing that happened to me with my Abit KT7A Verson 1.3 and my 2000+. First, do not assume that your processor is bad. Next, unplug your computer. Remove the case and find your CMOS jumper setting. Reset the jumper from default to discharge. This is in most cases going from jumper settings 1 and 2 to, 2 and 3. Keep the power plug out and let this sit for about 5 minutes. Now put the CMOS jumper back to default and plug in the power cord. Keeping the power cord out is important because there is a small amount of power going into the motherboard when your computer is pluged in. This stray power can make it hard for the CMOS to discharge compelety. If you got your computer back then make no setting adjustment yet. The next part you are not going to like. Using another computer go to Asus web site and read about your motherboard and the FAQ's. You will find you are not the only one with this problem. Also, motherboards can have the same part number but can also have different version numbers and each version does things differently etc. I spent 24 hours reading about my motherboard and after a little tweeking it now works like a champ. Last, if your processor is bad AMD stands by their 3 year PIB warrenty. I know because they honored theirs with me. Good luck.

Thanks for your suggestions I am able to run the computer at 100MHz Bus speed. But it's unstable and hangs many time. Tried going to 133MHz with CPU multiplier 12.5X. Doesn't boot up at all. Here I am not trying to overclock, but to run at recomemded speed. Any comments?

My guess is you might need a BIOS update?? With the new AMD XP you can not be behind in the BIOS. Also, even though your ram is from Crucial and that is a known good brand you mother board might not like it. That does happen. If your RAM stick is a single 512 then borrow some DDR from someone else and see what happens. If your Ram is not a single 512 then trade out each 256 and see what happens. Also, AMD made a slight frequency change to their XP processors that some of the motherboards that are a little older do not like and you must get everything perfect. In some cases a BIOS update will not address the difference with the motherboards that were made before the release of the XP processor. Motherboards that were made after the release of the XP processor over clocking is easyer than under clocking with some motherboards, (see how crazy this is?) like in the case with mine. There is no way I can under clock. However, I can go in and increase the multiplier and FSB to a higher setting with no problems. In some cases the FSB increase is off and on unstable. Anyway the minute I under clock my computer it will not even beap after power up and the monitor will not go on. This is why I remarked that you need to go read about your motherboard at ASUS web site, because this is a very common problem and each motherboard is diffrent. Also, do not just go by the part nummber of your motherboard. You need to find the version number as well. That will pin point some slight differences that might be important to your problem. That is why it is hard for me to completely help you. Like it or not you may be forced to do some homework. This is what I had to do and yes it was a pain but my computer is now working as advertised. Good luck.

Dear Navyretire Thanks a lot for your time in looking at my problem. I tried couple of things last night. First I tried using Jumper Mode in place of Jumper Free at 133/33 - No boot (Boots at 100/33) Second I upgraded the BIOS to the latest version 1016 - No boot at 133/33 Third I set the CPU/Memory frequency ratio to 1:1, so that memory runs at 266MHz in place of 333MHz - No boot Suspecting problem with memory I got a working SAMSUNG DDR333 128MB module from my friend and tried running at 133/33 - No boot. But system boots at 100/33, same with my Crucial. In fact SAMSUNG is recommended by ASUS on their website so does Micron. But not Crucial, even though it uses same Micron memory chips (Don't understand this ;-( So finally Memory is fine and problem is with either CPU or more likely board, as I bought an OEM version on Ebay. It was advertised as new and looks new. Is there any way figuring this out? Also I tried going thru posts on ASUS site. They are not really helpful. God help me...

You got me on that last question. I am not trying to be a smarty pants but I think you said it all when you said you got the motherboard from ebay and the seller said it looks new. I do computer repair and I NEVER keep anything that is broke. All broken hardware goes in the trash, period!! I do not care how much it might have cost at one time. Anyway, my guess is that these sellers knew the FSB did not work at 133 and figured "it does work so lets sell it". Baby your processor (because those XP's are great) and get another motherboard. No I take it back, first make sure that processor works through a friend and then get the new motherboard. Sorry and good luck.
