Fitted new Radeon 9700 Pro Pc runs extreemly fast,
Nature on 2001 runs 175 frames per sec at 1152x856x at 77.0 Htz by 85 Hz. Monitor Sony Trinatron running as above Temperature - System never goes beyond 32 Deg C cpu average 50c.

That is when it boots often have to switch on 2 0r 3 times before Monitor shows picture
How can I fix this please to boot first time all the time All other drivers are the latest.

1 trick that has done wonders for me on the KT7A, is to enter BIOS setup, and manually set the CPU speed.

There is a bug in the BIOS CPU speed settings where the automatic settings will set the speed to slow.
This affects many Socket A motherboards that use PC133 SDRAM, not just ABit.

Anyhow, assuming you have PC133 SDRAM, and an Athlon (not an Athlon XP) CPU, the speed settings are as follows:

FSB: 1/2 of the CPU FSB speed. The Athlon 1400MHz CPU is available in 2 different FSB speeds.
(If the Front side bus speed of your CPU is 200MHz, use 100MHz)
(If the Front Side Bus speed of your CPU is 266MHz, use 133MHZ)

Multiplier: 1400 / FSB
For the 200MHZ FSB (100MHz) Athlon, the multiplier on your system should be 14*
For the 266MHZ FSB (133MHz) Athlon, the multiplier on your system should be 10.5*

Memory clock: If you have PC133SDRAM, and you set the FSB to 100MHz, use CPU clock + PCI clock, or 133MHz.
If you used 133MHz for the fsb, set the Memory to use CPU clock.
If your CPU is an Athlon XP, you will need to adjust the multiplier settings to use the actual CPU clock speed, and not the 'rated' 1400MHz.

Thank you for your reply Unfortunately the problem still persists However I find that now if I press DEL on boot let that come up and then save and exit It boots as normal.
Wierd or what still thanks for taking the time to send a reply If you come across anything else please let me know

humm, new or old monitor? some monitors take a while to warm up, also, on very fast systems, you could totally miss the POST information and scoot right up to where Windows loads up before your monitor ever has a chance to display anything. try waiting a bit more and see if in actuality your system runs a bit faster than you you expected and what you thought you would see on your monitor your monitor couldn't display because of your fast system.

Thanks Friend Monitor is app 6 months old Dell sony Trinotron P900 or is it 990 and although running at 85 Hz I was running at 100 Hz prior to changing from Radeon 64 MB Vivo ddr with No problems.
Thank you anyway any further Ideas please let meknow

A couple things to try
#1. Make sure monitor is on before booting pc.
#2. shut off your power suspension options on the pc.
Good luck!
Sounds like a nice system!
