PIII 1000/100 on BX???

[bachlaw]

Despite this site's insistence in its P3-1000/133 review that gigahertz chips would be available only in 133 MHz bus varieties, there apparently are plenty of 100 MHz-bus chips floating around, according to Sharky's CPU prices, anyway. CPU prices

Is there any reason to think this wouldn't work in my Dell system with a BX motherboard? I recall Anand saying that there technically is no 8.5 multiplier to allow the 850 MHz chip to work in a BX, but that the chip automatically set it all by itself. Is there reason to believe that the 1 GHz chip would do the same thing?

I'd appreciate a review in the near future of 1000/100 vs. 1000/133, particularly to find out if the reduced (standard) bus speed of the BX hinders it all against the i815, etc.

There is a P3-1GHz with a 100MHz FSB, but it is only available as a Slot 1 processor, and not an FC-PGA.

S-specs are SL4KL (retail) and SL4BR (OEM).

Since all Intel processors are multiplier locked, the maximum multiplier supported by the motherboard does not matter as the processor will ignore whatever setting the motherboard has and use its own.

I assume that the motherboard in your Dell system is an Intel SE440BX or SE440BX2. In that case, you will need to look for a BIOS update and make sure that your system supports the cC0 stepping processors. This would probably be my biggest worry. Your motherboard should have voltage support for this processor.

I would not think running the FSB at 100MHz is all that much of a hinderanceas compared to runing at 133MHz ....it still performs very well.

sorry to differ but my wholesaler had both flavours ie slot 1 &amp; fc-ppga 100fsb, on sale not long ago.

I only see the Slot 1 SL4KL and SL4BR according to both the QIT and Specification Update.

Actually the difference between the E and EB is quite big.
The 1000/100 is also a bit pricier. I´d recommend you to change to PC 133 memory while the
low prices last, you won´t lose so much $$$ then. If you don´t need the money you´ll get when you sell your stick/s of PC100-mem on the instant, put them away ahile and sell them when prices have gone up a bit. If your mb supports 1/4 PCI-multiplier the only thing which have to run oc:ed is your AGP-card, and it´ll probably make it...Your mb however needs some options for the AGP-card, like queue-depth and AGP transfer mode. These should be set to low or something like that.

If your mb doesnn´t support the 1/4 multiplier You should consider getting a new mobo.
That´ll set you back approx. $100.

Andy,

you are right: it does seem to be a BX-2 board. Like the Intel processor support chart, my Dell documents say the highest supported processor is 850/100. That, of course, makes one wonder exactly what board the 1000/100 was intended to run on. How strange. Thoughts, anyone?

<< say the highest supported processor is 850/100 >>


could simply be that the multiplier settings for the m/board only go up to x8.5. since the intel processors are now multiplier locked, that limitation should not now apply IMO!

Im sure a bios update will be avaliable..they prolly havent been out long
