Re: PCChips BKi810 BookPC - Repairing Dead PSU?

Is the input fuse blown (the round thing that says T2A 250V)? If so, you also have a short somewhere on the primary, making the whole situation even more problematic. Personally, I would try to fix it out of curiosity and to test my skills, but it certainly isn't worth it for £30+. The caps should …

no problem with multi rail , but 5V might e a problem if board doesnt have 12V power connector, did all P4s have one? All Pentium 4 motherboards have a 12V connector This is not true as a general statement, for example: https://theretroweb.com/motherboards/s/ecs-p4vxad-plus-1-0 Or: https:// …

Because it certainly makes sense to buy a 1600W power supply just to get 25 amps on the 5V rail... I get that modern DC-DC designs are technically superior in every way, but a decent PSU (potentially recapped if necessary) from 2005-2009 is more than good enough.

What exactly is the model of this board? I was not able to find it on TRW. In any case, it's a nice VIP board, definitely worth saving.

I thought about that just yesterday: what is the purpose of the diode? It prevents voltage coming from the rest of the board from reaching the battery I guess. In case someone plugs something on the external battery connector I guess? I mean, it's unlikely but probably a "good to have". If the …

If the chipset is really the VIA VT82C693 as listed on TRW, you will only get 100 MHz FSB support. However, when I Google the name of the board, I get Chinese websites that reference the 693A chipset. That one supports 133 MHz FSB. In any case, Tualatin will NOT work.

Not trying to thread necro, but what series of caps did you use to recap the enermax with PCE-TUR? I recapped a 465-VE and 301-VE with Rubycon ZLJ and they must be too low ESR as my oscilloscope has them oscillating on the output unfortunately. Also you are totally correct on these crappy caps …

Yeah, that CPU is slowly being cooked at 3.4 V. Any "regular" Pentium (non-MMX) should be a good replacement.

Is the one that was attached to the bigger heatsink faulty? That one generates 3.3 V. The one with the smaller heatsink generates 2.8 V for MMX CPUs. After a quick look, D45H11 is widely available and it looks close enough according to the specs.

Did you try jumpering the CPU to 1.5x66 MHz instead of 2x50? I'm not sure that it would make any difference, though. The 3.3 V LED being off is normal on the POST card, there is no 3.3 V in these PCI slots. However, your main problem is the RESET light being constantly on. In this state, the CPU …

My recommendation is a socket 478 motherboard with Intel 865PE chipset if you are looking for something that can be classified as retro. They typically have two SATA 1 ports and work perfectly with modern SSDs (unlike the dreaded VIA southbridge). You can even use the CPU that you had back in the …

The problem most likely has something to do with the VRM becuase the DX2-66 runs straight off the 5V rail provided by the PSU, and that's why it works. Normally, I would advise you to change the caps in this situation, but they seem to be good brands (Rubycon and Elna judging by the vents). I am …

Well, here is my result. Standard Intel DX4-100 (S-Spec SK051, write-through) on Soyo SY-4SAW2. It is identical to yours. Therefore, I think we can conlude the "correct" score for this CPU is exactly 197.1. Filename DX4-100WT.jpg File size 543.59 KiB Views 800 views

Actually, I find Norton System Info to be a very good indicator of a particular CPU behaving correctly or not. If I remember correctly, a DX2-66 should score exactly 144.0 in this benchmark if properly configured on a decent motherboard, which makes sense given the result for DX-33. This would put …
