i just purchased for a friend the following:

a7v8x-x moboard
xp2600 chip
1 gig of pc2700 ram (333)


it will not stay running stable at clockspeed of 2083. on the install of
win xp, it rebooted several times during setup and never made it all the
way.

i had to drop it down to 1667 in the bios to get it stable. also when i
switch it to 2083 in the bios, a little red warning/question on the right
side pops up
and says to make sure the ram is 333mghtz. well isn't pc2700 ram. and an
xp2600 chip 2083?

i have an email in to asus and the company i bought parts from, but not
expecting emails back til monday or tuesday, knew i would get a better
response and more helpful answer with this newsgroup. am i missing
something in the setup, maybe a jumper somewhere? i have not messed with the
defaults, and the book doesn't have a troubleshooting section in it.

thanx for any advice in advance.

I think a 2600 runs at 1800. 1667 is the real speed of the XP 2000 chip
and 2000 is the real speed of a 2400 chip.
If anyone else reading this has a conversion chart will they please post it
?

Hi, My XP 2600 runs at 2083 normally..not over clocked.

Sounds like could be bad RAM, try removing 512 if you have 2 sticks?
A bad or under powered power supply can cause reboots installing windows.
mis-marked CPU?
and says to make sure the ram is 333mghtz. well isn't pc2700 ram. and an

I'm going to go out on a limb here and say that you likely need to upgrade
the PSU unless it's a brand new jobbie. I had similar problems when I was
trying to install this same board + 512 pc2700 + 2600 + ATI 9500 pro into
the chasis that I'd been using for years with an old 300W PSU.

What was I thinking?

If your PSU is solid then do try alternating the individual sticks of RAM.
The newer ASUS boards seem to be a lot more picky about RAM and RAM setings
in bios etc. It's a hit or miss deal. I'm using Corsair Value Select RAM
(AIDA 32 tells me it's Spectek) and I've done a fair amount of tweaking to
find the sweet spot.

There's no reason short of a bad board that your setup shouldn't work spot
on. As we speak I;ve got this rig up to 2403.3mhz (13.5x178(x2=356)) and I
can't tell you how happy I am with that. Normally I run it at 2.083ghz.

As far as that warning goes I can't imagine why it shows up. It's like
saying you shouldn't underclock. I'm sure there's some logical explaination
that eludes me.

So the check list is PSU, memory and don't forget to make sure you have a
good HSF. I imagine this all starts to sound like a broken record after a
while but it bears repeating.

Good luck

A question arises here with "(AIDA 32 tells me it's Spectek)". As Aida 32
can only read from the ram what it is, I think an email to Corsair would be
in order to verify I had the real thing.
As for the CPU speeds, the older 2600 chip was a 133fsb whereas the later
"Thoroughbred" 2600 is 166 fsb therefore it`s real speed is 2.083.
Only two thoughts come to mind and the first is that the ram is of
questionable parentage and not any of the approved ASUS ram brands.
The other thought is that the cd rom drive isn`t loading a faithful copy of
Win XP onto the hard drive. Having said that, dodgy ram will also produce a
bad layup of an operating system. It sure gets complicated, doesn`t it ?
 
Having reread the original post " on the install of
win xp, it rebooted several times during setup and never made it all the
way", I have to think that it is a ram problem especially with this
motherboard and I would suggest that a couple of sticks of branded ram be
borrowed and the HDD be formatted and Win XP be installed fresh again.
 
Well, this is Corsair's 'Value Select' RAM which means it isn't top of the
line and likely outsourced so, I'm not terribly disappointed.
 
Thanx for all the information,


this was a complete system order for my friend, case/powersupply all the
way to a monitor, mouse and keyboard. So everything is brand new. I
personally have an asus a7v8x board with the same ram 1 gig of kingston
value ram (2 sticks of 512) and a 2600 chip. so that much except the "-x"
on the motherboard is identical. i pulled my ram out and placed it in that
board, same error. i pulled my cpu out and placed in the board, same
problem. so i am guessing the moboard is bad.

the tech at the company i bought the pieces said last option flash the bios.
so i went from 03 to 05 and still had the same problems.

if any part of the ram is bad, underclocking the cpu to 1667 would still
generate the same results correct? i underclocked the chip to 1667 and
everything runs great, i ran sandra's burn in wizard several hours last
night with it at 1667 and never a hickup. but as soon as i set the
clockspeed to 2083, it starts all kinds of lockups / restarts and even some
blue screens of deaths.. i thought winxp took care of that problem.

there aren't any special jumpers that i am possibly missing to allow "jumper
free" mode or anything else? i am grasping for an answer.

the tech at the company said if nothing else, call the customer service line
and get an rma and send it back.. but this is further delaying my friend
from his new computer..


Once again for all the people who responded, and the information shared.
