I've hit the "wall"........help!

[Michael_Myers]

Hi,
System specs:
Abit KT7a (non raid)
Duron 800 mhz
win98 os

I ONLY (so far) have used the option in the softmenu III
that lets you change the FSB of the CHIP itself. You select "User defined" and then the Cpu FSB multiple I have 18, which yeilds a 947Mhz reading according to sisoft. (about right)

18 x 8 = 144. 144 + 800 = 944.

I had to bump the voltage up to 1.85, AND I had to bump the I/O voltage to 3.60. Otherwise it won't post, and I have to clear the cmos.

This seems to be my "wall" that I can't get past. Any suggestions? I really don't won't to unlock the L1 bridges on the chip yet if I don't have to. Lemmm'e know what you think. Thanks

It's unclear to me what your FSB speed is..I use the reported CPU frequency and divide it by the default multiplier(944/8 = 118Mhz FSB)

That's the best that I can reason. Since you've raised your Vcore to the limit of the motherboard, and raised your VIO to +10% of default..the highest value that you should use and expect relatively long component life..you may have indeed "hit the wall".

All is not lost, as you can try and boot at 8*133=1064, but I suspect that you will not be successful. This is also dependant on your RAM being up to the task at hand as well.

Your only other reasonable option is to connect the 'L1' bridges, and with multiplier control, experiment with different multipliers, FSB speeds and combinations of voltages.

Since you did not report any temperatures, I must ask what your reported temperatures are..all of them, and how you are arriving at them.(MBM, or some other hardware monitoring device)

An inventory of your cooling set-up will be beneficial as well. Your system specs. are far from complete. A complete list would be helpful.

Ahhhhhhhhh

Well, using MOBO monitor, 5.07b, My temp readings are 38c cpu, 34c case, and 22c northbridge chip.

As for what I actually changed in the BIOS......
It was "CPU FSB PLUS (MHZ)"

On the Abit KT7a board. Instead of raising the FSB on EVERYthing in the pc, you are supposed to be able to just change the FSB of the CPU using the setting above, in 1mhz increments. I got as high as 18, (we have been through the math) and got a reading of 947 MHZ using sisoft. Using the default Voltage settings of 1.6, it would NOT post. Using 1.85 v AND a VIO of 3.6 (just because it "felt" right)
It posted fine, and I am up and running with the specs you currently have..........

RAM.......Micron, CAS 2, 1stick, 256 MB........

1 13 gig HD, 5400rpms............Viper 550 TNT card...

What else you need to know????????? Thanks.
