Strange behaviour

[benjit]

Hi all, strange one for you.

Ive swapped out my old athlon 64 X2 for a phenom ii 545(old potato of a thing I know)

The strange thing upon first boot I forgot to reconnect the CPU 4pin cable.. the system booted perfectly and even ran stable.. once the thought passed through my head that I possibly didn't plug it in, checked and reconnected it there was absolutely no difference.

 

Now im pretty certain the thing shouldn't have posted in the first place.

Does your board have multiple EPS connectors? for example an 8 Pin plus a 4 Pin, the CPU would never work without any power from any of those connectors.

Sometimes a CPU can run without the extra 4-pin connector if it doesn't use that extra power. You probably would have noticed instability if you stress tested it though.

Maybe the system was heavily downclocking in the mean time. But to be honest, in modern times when the EPS connector is non connected, usually the system will start up and a black screen with white text will tell you that and tell you to plug it in.

This things ancient, it has the 4pin eps plus the standard 24 or 20 pin connector(haven't counted) I've been Mr laptop and tablet man for the last few years. Fired it up out of curiosity, discovered it was shite so plopped a £10 CPU plus 4gb of ddr2 that cost me 4 quid plus a wait for it....GTX650!!!  and was quite surprised at how well it ran.

Hmm that's strange, it shouldn't have ran without the 4pin, they directly connect to the VRMs and I don't think there's any traces to the VRMs from the 24pin unless it's an OEM board with weird proprietary connectors so they might have violated the standards as usual, meaning the 24pin has a different pinout than the ATX standard.

I'll post a photo later on.. the board design is shocking

They could keep the ATX standard though but having traces to the VRMs is not ideal and I haven't seen that yet.

If it's a weird design then it's definitely OEM

It's not OEM, it's Chinese tat
