Using the SoftMenu section of the BIOS of my Abit KT7A motherboard, I can freely adjust the CPU multiplier. Among other things, this allows me to downclock the CPU to 500 MHz. This is useful when dealing with speed sensitive games. Interesting!!! Your combination of KT7A + Thoroughbred is able to …

I have re-capped several boards the last years. After starting re-capping of the most critical capacitors on selected boards, during that time i have not bought a desolder gun, i have used this multitool (dremel) to drill out the remaining solder at small holes. With this approach you have to take …

Well, this was my assumption also, that JP 6 ,7 and 8 are for IRQ.... to the CDROM. But there is also jumper JP, which is pictured at the cards back: JP3: IRQ 14 - Primary IRQ 15 - secondary Well, i don't care about the CDROM interface on this soundcard, cause i have two IDE port on a controller …

From my point of view, the only possibility that it's muted , it can be through jumpers. As you can see the 1st link in this thread, i had shown some pictures of this card some years ago. The problem is that there are no all jumpers decribed on the backside of this card. From my point of view, these …

Thanks for your info. I have bought this cable. But i have still problems that i don't hear any sound from a playing audio CD. Either when it's connected to the Mitsumi CD-In header or the Panasonic header. About your website you've linked. I am a little confused to be honest. The cable I've bought, …

My PSU criteria for ATX builds are simple. 1) Japanese capacitors or equivalent and 2) 5VSB standby circuit that uses an IC, and not a two-transistor design. If your PSU has the old two transistor design, your cooking the innards while the computer is off. You can see this for yourself if you …

How did you remove heatsink on this particular model? Epoxy was used as TIM. Well, i really do not remember... Maybe i had to pull the heatsink with a force which is little bit than usual (compared to other heatsinks of this era). At the end i was happy to remove it, on the chip are some marks …
