At least, it is an interesting board. Not really common compared to other socket 7 boards with 1, 2 or 3 ISA slots. A full PCI setting on mainboards, this is becoming standard during the release of most Athlon boards, at least starting the VIA266 chipset. Despite of having no ISA slot, i agree this …

Yes , you're right. It is not the most powerful iron. The nominal power is 48 watts, and it's temperature range is 150°C to 450°C. Actually, i am soldering with a temperature of 340°C to 343°C mostly. So , i had powered up to 365°C to remove step by step the tin-solder around the wire. I have used …

@ SBlive You have written that most of the parts are NOS (now old stock). About the Enermax EG465AX-VE, is it also NOS? Even when it is NOS, the capacitors will age nevertheless.

I have made some power consumption tests to my Athlon Thunderbird. Because on wiki list, Athlon (Model 4, "Thunderbird", 180 nm) , there is the TDP shown only. So, what i want to know is, how is the consumption @idle load and @100% super-pi benchmark. Here are the results. Setting 550MHz 550_1.jpg …

TDP is meant for cooling systems and can be quite arbitrary. NetBurst was horribly inefficient in power consumption compared to Intel P6 microarchitecture and AMD offerings at the time, the only thing going for it was the SSE2 instructions and HT if that P4 CPU supports it. Actually, i have here …

IMHO a Tualatin paired with an MB with one ISA slot worth far more than a NetBurst P4 2.8 GHz for retro computing, particularly if the latter is a Northwood (same 130 nm lithography as Tualatin) that burns three times of electricity with minimal performance boost. TDP of Pentium III 1400S : 32.2W …

baguete wrote on 2021-06-21, 16:09: E8600 @ 4,86GHz This is an amazing clock. A reduced multiplier to 9.5x and a FSB of 512 Mhz would result because of the FSB strap: 10x / 9.5x = 1.0526... 1.0526 * 512Mhz = 539Mhz --> Northbridge clock. Do have measured the CPU temps and the NB temps especially?

I agree with Doornkaat. This chipset supports only FSB 133 officially. https://www.viatech.com/en/silicon/legacy/chipsets/km266/ --> 552-pin BGA VT8375 North Bridge wikipedia is listing a 'KM266 Pro' chipset which is not existing on the official website. https://www.viatech.com/en/silicon/legacy/ …

1.) Ok, as you have already enough w98 alternatives ready, you don't need any boards with ISA slot. So you can exclude the slowest board with KT133A chipset. 2.) Regarding the power supply, i would advise you to use PSU's with at least 30A or higher on the 5V rail. Do not underestimate the power …

That's the reason why i am still using a K6-2 500. The 2+ and iii(+) prices are way too high compared what i've paid for my K6-2 or my athlon thunderbird. The thunderbird i can clock @550, 600, 650 ... and further on. I think, i've paid 3€ - 4€ for the thunderbird.

It depends... Does the MSI K7T Turbo2 have an ISA slot populated? On google search i see versions with or without ISA. So in case it's there and you want also a good DOS compatible PC then i would take this board. If you have an Athlon with 133Mhz or 166Mhz FSB, then i would go for the other KT333 …
