Windows not picking up hardware

[hitman67]

We recently upgraded a Mate's PC with a New Mobo/CPU/Ram combo pack and it all seems to be running fine apart from Windows thinks it's a lot less powerful than it is.

We put in:
AMD Sempron 2600+
512mb Ram
AsRock K7VT4A Pro Mobo

Windows Picks up:

And CPU-Z Picks up:






So Basically neither can pick up the Sempron, but CPU-Z gets the Motherboard and Ram right. Anyone know why this is happening? Possible ideas include the FSB Set to 333 and not having SP1/2

What does the bios see?

Your FSB isnt in 'sync' with your processor which is the first problem as the Sempron has a Mulit of 12x and your fsb is only 100 you need it set at 166 I believe to use it properly

Have you updated the bios so it recornises the sempron?

We bought it as a CPU/Mobo set but we'll try all above, thanks people.

I have friends who experienced this before, because they simply mis-aligned the heatsink and fan (really only goes on one way!)
By flipping it around, that solved the problem (of course after re-applying the thermal compound.)

Ok the plot thickens... We managed to get the FSB up to 133 but then the PC crashed and doesn't start. Power is getting round the whole system but it doesn't do a system test. We pulled out all the parts except for the CPU one at a time and that didn't help either.

Next we took the Mobo battery out for about 2.5 Minutes and it still refused to work, so, anyone any new ideas?

more than likely the fsb went up, while still keeping the ram at a positive multiplier so it was running at somewhere in the 166 region. Have you reset the cmos using the jumper (while the thing is earthed). Try holding down insert while booting. Failing that, you may be able to get it to post to change the settings with a stick of 3200.

Where is the CMOS switch on an AsRock board? I was saying that to him last night and we couldn't find it.

[herulach]

itll just be a jumper not a switch. ive no idea where it is. havent you got the manual?

The information I have says that a Sempron 2600+ should run on a 166Mhz/DDR333 FSB, with a multiplier of 11x. You've got your FSB running at 100Mhz/DDR200 with a multiplier of 12x (if you believe what CPUz says). I thought Sempron models were multiplier locked and only Sempron 2800+ and 3000+ models should run at 12x, are you sure your processor is a 2600+?

How fast is your RAM? Is it PC2100 (133Mhz/DDR266), PC2700 (166Mhz/DDR333) or PC3200 (200Mhz/DDR400)?

If its PC2100, you'll want to run it at 133Mhz (FSB - 33). PC2700 will run at 166Mhz (FSB) where as PC3200 will either run at 166 Mhz or 200Mhz (FSB +33).

Will pass all this on next time I have chance - Thanks for all the suggestions people.


And this morning, the whole thing doesn't start, feeling PSU or Mobo are smegged.
