Compaq 7594 Processor Upgrade - How Big?
Currently a Celeron 566. How fast a Celeron can I put in here? Do I have to
stay at the 66 MHz or can I put a faster one in? How about a Pentium 3? How fast (if at all) with one of these can I use? Thanks. __________________________________________________ _______________ JG... Jeff Givens "My hovercraft is full of eels." |

Board itself should support at least any P3 with 100MHz FSB, but I don't know about the 133MHz FSB versions of P3. Likewise a Coppermine Celeron (FCPGA), not Tualatin (FCPGA2) should work. The other issue might be if the bios halts the system when it doesn't recognize the CPU, even though it could've ran fine if it hadn't halted "for no good reason". Checking Compaq oriented newsgroups you may find reports of whether bios does halt system if unknown CPU is (isn't) properly identified. Odds are it'll work fine given the 100MHz FSB constraint I mentioned above. |

Speaking of, anyone know who the actual board manufacturer of these is/was? I haven't pulled it out but had looked around and see nothing but a Compaq sticker, nothing etched on the board though. Maybe on the backside. Thanks. __________________________________________________ _______________ JG... Jeff Givens "My hovercraft is full of eels." |

Flash bios with old CPU in the system, might be good to do that even if you didn't upgrade the cpu, since it might add support for larger hard drives or fix other bios bugs... even if you didn't know you had any bugs. Board itself should support at least any P3 with 100MHz FSB, but I don't know about the 133MHz FSB versions of P3. Likewise a Coppermine Celeron (FCPGA), not Tualatin (FCPGA2) should work. The BIOS is so basic (old one), hardly any info given and definitely no settings to help in this matter. CPU multiplier and voltage should be set automatically. Sometimes the FSB needs set by bios or jumper... check manual if available or silkscreening on the board. It is also possible the FSB would be set automatically too, it was common for Coppermine era motherboads to do so. If there is any setting you might change in bios now (if the setting exists in bios at all) is one worded something like "halt on error", which could be set to "no", "none", etc. hadn't halted "for no good reason".

Maybe on the backside. Think FIC made some and Mitac others. I doubt it's on the backside of the board but there could be a sticker on the (bottom) side of the bottom PCI or ISA slot. Best suggestion is to just buy CPU from someplace with a good return policy if you can't get it dirt cheap... but then again it could always be resold. Typical symptom of a Compaq with unworkable CPU installed is that whole system seems dead (yet will work agagin with correct CPU installed. You might also try clearing the CMOS (either via jumper or removing battery for 10 minutes, while AC power is disconnected from power supply), if the system doesn't run on first or second power-up attempt after swapping the CPU. |

Think FIC made some and Mitac others. I doubt it's on the Good call, turns out to be a PWA BMW which is a MiTac 6513wu. Takes up to 133 fsb but I still don't know it's max processor freq. Found 1 cite where some guy claimed up to 1 GHz. http://www.mitac.com/micweb/products...3wu/6513wu.htm __________________________________________________ _______________ JG...

Max CPU speed generally isn't a specific MHz model but rather a family of CPUs... in this case with the 133MHz FSB support it should run any Coppermine CPU, the question being whether Tualatins are supported, and if so it should run any Tualatin though it's onboard power regulation circuitry might not be the greatest for highest speed Tualatin CPUs. It should at least run the fastest Coppermine Celeron or P3 CPUs, which went up to 1.1GHz (Celeron) or 1.13 GHz (P3), IIRC. Note that there was overlap in the Celerons, the Tualatins started at around 900 or 950 MHz so "IF" it wouldn't run the Tualatin you need be sure to get the Coppermine version. |

Yeah, just to be safe I'm staying with the 0.18u architecture. I just bought one off ebay for $40 US, 1 GHz. Thx for the lead, Compaq is *so* unhelpful, the web site anyways. __________________________________________________ _______________ JG... Jeff Givens "My hovercraft is full of eels." |
