Would a Q9650 be any good? I hear they don’t run as hot. Q9650 or QX9650? The Q9650 is a 95W TDP... i have a core 2 quad 9650, would that be an upgrade to the qx 6700? The Q9650 is a 45nm CPU vs a 65nm, its standard clock is 333 MHz higher and cache is 50% more. Yes it's an upgrade (unless the …

Just out of curiosity - what country do you live in? I can't think of any place in Denmark, where I could go in and have a 20 year old board diagnosed and definetely not repaired. That would be contacts in the retro community if anything. And I would always, as in always go for an Intel chipset, …

Couple of 800 EBs - mostly for the big heat sinks, which fits great for my P2B-DS 120mm fan adapter. Also an SL4BR, which will hopefully behave together with an SL4KL on said mainboard. They are same stepping albeit not same sSpec. I guess it would work ...?

First question you should ask (and verify): the motherboard supports the 2.9 voltage? According to the information available it doesn't. I made a mistake, my board is PT-2006 and it does support 2.9V and even 2.5V. Multiplier jumpers only go up to 3x so probably no 3.5x support either for PR300 but …

As pshipkov mentioned, I need 5.15 V going to the SXL2 for stable operation at 90 MHz. I only need 3.85 V for stable operation at 80 MHz. That should read 37 C on VRM heatsink, steady-state, with only the linear reg. I've fixed it now. Wire your regulator to +12V and +5V to get 7V Vin. You'll need …

Huh, I guess the 6V from the Application Report was accurate. I honestly didn't think it would allow for it. I'm impressed at the operating voltage range of the 486 SXL2-G processors. I don't think I know of another processor in the 386/486 family that can operate anywhere close to that large of a …

Ib think somewhere back in the 90s, it changed. Back on AT power supplies and early ATX, the fans blew air in to the cabinet, counteracting the natural convection. I remember I turned my fan around and actually got a bit lower temperature. But yeah, that was back when an extra 80mm fan supplementing …

Oh yes, part OKI-78SR-5/1.5-W36H-C from Murata is the thing for a 5V part. It's most likely also available in an upright version; alternatively, the pin headers can be changed. RS Components item number 796-2138

Come to think of it. There does exist plug-in buck converters in TO-220 footprint as replacement for 78xx series. Since they are buck converters on a PCB with a handful of components, it may be possible to replace feedback resistors for another voltage than 5 volts. IIRC they are +90% effective ... …

Maybe I can add a few parallel power resistors to the 12 V feed to not put so much burden on the VRM? That is, get Vin down to 8 V. If you know your maximum current draw, yes, that is an option. The resistors, of course would dissipate the power and get hot then. At 2 amps, you'd need (12V-8V) /2A …
