A tricky problem. I have a HP system, which I have systematically upgraded/changed.
The problem is this, the motherboard (HP:Tango-GLA) came fitted with celeron 2GHZ. According to HP, the motherboard can support up to 2.53GHZ P4 with FSB of 533MHZ. I duly fitted P4 2.4GHZ, with FSB 533MHZ. The problem is, the chip is running at 1.8GHZ (FSB400MHZ). Now, I have checked all of this info via BIOS, Intel chip frequency utility, and others, and chip is correct type, but running slow. According to HP, the motherboard should automatically adjust to the new processor. A kindly soul at HP tech support spent two hours on the phone to solve problem, but could not. To sum up,
1. tried re-setting CMOS via jumpers on board, - at checksum error re-set to defaults.
2. tried also removing battery. No effect.
3. In BIOS (latest version 3.17 phoenix tango) it is not possible to adjust FSB or CPU multiplier directly.
CPU is retail boxed from good supplier, PC still boots fine, with no problems whatsoever. So, from my limited knowledge, it seems to me the problem is that the board is not setting the FSB speed at 533 (up from the default 400)MHZ. Hp tech support do not believe there are jumpers on the board to achieve the required change. HP admitted they could not solve the problem (and the guy did seem to know what he was doing).
Aside from HP, it is difficult to find any info on this board - as you may expect,the system is not supplied with a motherboard manual.
RAM is 1024MB PC2100 DDR, so should be fine with new FSB speed.
Chipset is Intel 845G - so again should be ok.
Intel frequency utility, sisoftware sandra, and others all identify FSB as 400MHZ, chip type as 2.4GHZ P4, running at 1.8GHZ. Is it correct to think that the root of this problem is the failure of the motherboard to 'up' the FSB to 533MHZ?
BIOS is unchanged from original settings.
As I am relatively new to all this, any suggestions to try would be most appreciated. Many thanks.
