Pix 525 cpu

Unanswered Question
Sep 6th, 2010


I have read that any p3 1.75 volt coppermine 100 mhz fsb will work as an upgrade for the Pix 525. Intel released a 1.13 but then recalled it because of instability issues but then re-released it with a geneal stepping fix(beyond their abortive first attemopt to tie it to a few special boards. This chip

SL5QW PIII 1.10 GHz 100 MHz 256 KB RB80526PY005256

the  the one i am wondering about.

A 1.13 GHz version was released in mid-2000 but famously recalled after a collaboration between HardOCP and Tom's Hardware discovered various instabilities with the operation of the new CPU  speed grade. The Coppermine core was unable to reliably reach the  1.13 GHz speed without various tweaks to the processor's microcode,  effective cooling, additional voltage (1.75 V vs. 1.65 V), and  specifically validated platforms.[3] Intel only officially supported the processor on its own VC820 i820-based  motherboard, but even this motherboard displayed instability in the  independent tests of the hardware review sites. In benchmarks that were  stable, performance was shown to be sub-par, with the 1.13 GHz CPU  equalling a 1.0 GHz model. Tom's Hardware attributed this performance  deficit to relaxed tuning of the CPU and motherboard to improve  stability.[4] Intel needed at least six months to resolve the problems using a new  cD0 stepping and re-released 1.1 GHz and 1.13 GHz versions in 2001.


The only difference I see in the 1.1 is that it is called socket 370 while the others are socket 370 slot 1

I have an unrestricted bundle pix 525 so the way I read it it will support 1 128 eec and one 256 eec.

Now is that just the official support but a 512 low density eec chip would work?

I have this problem too.
