Just trying to build a PC, have set up the jumper to take 133/266mhz memory. The memory is correct, but will not boot. When I change it and but some old 64 SDR ram in, it runs fine.
I have now taken the jumper out, put the new memory in and all runs fine. My question is;
Why?

Nobody can tell you if you make such vague statements as "the memory is correct". What is 133/266Mhz memory setting?
ie.What kind of mobo is it. etc etc. Modern boards don't need jumpers changing to affect memory speed, it's a bios setting.
If I wrote why won't my car won't start when I know the key is correct and it is blue..... You see what I mean?

Barry,
Motherboard is a 830 CF, Chip is an athlon XP 1600. Memory stick is a 256MB-32Mx64 Dimm PC133-SDRAM.
Re-reading the manual, the jumper I have removed to make it work is the CPU Front Side Bus Frequency Setting. With the jumper in place, this was setting it to 133Mhz/266mhz, and the machine would boot into XP, then Blue screen with a stop command. Looking on MS site this was down to faulty memory, but this was a brand new stick of memory as I sent the last lot back. So I removed the jumper, and now it boots and runs.
Originally I had the same problem when building the machine with XP, (above mentioned jumper in place) so took out the memory and but some SEC Memory in (64 SDR) and everyhing ran fine. Hence why I thought that it was faulty memory.
As I have never done this before, I am at a loss as to why it happened. Can you tell me where the memory setting is in the BIOS? and what it should be set to?
Any ideas would be greatfully received!
Chris.

Have a look at pages 12-14 of the mobo manual. Oh, and also page 40 bizarrely.
It looks from what you say that the PC133 DIMM you have won't work with the host clock set at 133Mhz. But it is happy to run at 100Mhz, (which is the motherboard's default) and as I recall that was the standard, in that PC133 DIMMS are compatible, but just run slower in a 100Mhz set up.
If you look you can see that the bios allows the host clock to be hardware controlled (ie. the jumper) or software controlled, (ie. the BIOS) and when software controlled can be incremented in (presumably) 1 Mhz steps. Try it and see at what point the memory stops working. Could be it just ain't up to the job.
So perhaps PC133 is just the name of the shop?
