Help: Fastest AMD for Via KT266A

I read in a recent issue of Australian PC User a table with the maximum CPUs that different chipsets can take. The KT266a, according to that table, can take up to a XP 2400+. Palominos stopped at XP 2100+, so I can only assume that Tbreds are supported (perhaps with a BIOS upgrade, perhaps not). I downloaded the manual for that motherboard and it isn't very helpful. -- spammage trappage: replace fishies_ with yahoo |

" On the manufacturers website, there isn't a detailed list of BIOS updates for that motherboard. All it has is a download link for one BIOS, so you might be running that one already. I recently helped someone with a similar query, and they had an Acorp motherboard with the same chipset (KT266A). The Acorp BIOS update page had a BIOS update for that motherboard which supported the 266FSB 2400+ and 2600+. The Acorp motherboard with KT266A chipset: http://www.acorp.com.tw/Products_inf...lt/7KT266A.htm The Acorp BIOS update page: http://www.acorp.com.tw/BIOS/BIOS%20...os-via-462.htm The 2600+ Thoroughbred is difficult to get hold of, as production was halted shortly after release. You'd do better to find a (much cheaper) 266FSB 2400+ as they are more easily available. The 2400+ was first designed with a Thorougbred core, but on release of the 333FSB Barton (2500+ and above), AMD re-designed its 266FSB range of Athlons with the Thorton core (2400+ and below). This was purely down to manufacturing costs, as this site explains. http://www.xbitlabs.com/news/cpu/dis...022184805.html |

In addition to the chipset there's also the issue of signal strength on some lines to the processor. In other words, Australian PC User assumed only the FSB mattered, but I've had at least one KT266a that wouldn't accept anything faster than a Palomino, and lesser KT133 boards that wouldn't run anything faster even at 100MHz FSB. Best course of action is to hunt down users of that particular board and see what they're running, or update bios to latest and just buy the CPU from someplace with a good return policy. |

Best course of action is to hunt down users of that particular board and see what they're running, or update bios to latest and just buy the CPU from someplace with a good return policy. What is the speed of the FSB for the Palomino? 133MHz FSB clock rate, often called DDR266. What is the fastest processor in the Palomino range? XP2100, but that model comes in both Palomino and Thoroughbred, if you saw no mention of it being a Palomino it probably isn't. Do you know where I can find power consumption figures for the Palomino's? AMD's website? They have spec sheets listing that, or a Google search might find it. Offhand I'm guessing an XP2100 is about 70W max, typical closer to 50W, which at one point was looked upon by Intel fanatics as really hot running, but now that Intel has 100W+ chips the perspective is a little different. If anything Palominos are easier to cool now than previously due to more large 'sinks in the market, and the larger core area of a Palomino reduces the need for highest efficiency heatsink base... you might have problems with a $8 'sink but certainy for under $25 there's a few choices. Then again a Thoroughbred or newer might work on your motherboard, I just don't know. The faster the chip the less likely it is to work from an amperage perspective too, that board was designed around older CPUs that used less current. It could run for awhile then fail prematurely. If it were me at this point I'd be thinking about upgrading the motherboard and memory, then whichever CPU fits the budget, many people feel a Barton XP2500 is a good choice. |

Am I limited to Palomino's? No, as long as you replace the PSU. You'll may even have problems with a Palomino with that PSU. Replace the PSU and you should be able to run any 133MHz (/266) FSB cpu. Best buy would probably be the 2400+, but you should also be able to use the /266 MP's like the 2800+. I can't afford to upgrade my PSU. My PSU can deliver the following. Is this enough power for a low-end Athlon? Which speed cpu would be the best? Surely you can afford this. Got one. Works well even with Athlon 64 power hungry cpu. http://www.amamax.com/psspecial2fnlp6100e.html -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) http://mysite.verizon.net/res0exft/cpu.htm |

And it's 266MHz (or 200/333/400). More specifically, it runs on a 2X multiplier on the (FSB-) clock that also controls cpu-speed via another multiplier. The FSB is not the memory bus. The FSB connects the cpu to the Northbridge. The memorybus is between the Northbridge and ram. And DDR266 (double data transfer rate) runs on 133MHz. ancra |
