A few hours ago I sat and tried some different cpu voltage selections to feed my ever-hungry amd.
I normally run my 1.8V t-bird 800 at 1.65 (mbm shows 1.696) after a quick reboot at 1.8 (won't start up normally at 1.65).
This time I tried 1.60V, and to my luck (I thought) it booted, a while back, before I started running at lower voltage than what is recommended, it wouldn't boot at all, no matter what, at anything lower than 1.65.
Now what happened at this voltage is that some strange, extremely high pitched noise ripped through the air... causing my ears to make this loud shriek... which persisted after I hastily shut my computer down.
Filled with terror, I started to "trouble-shoot" after some glasses of water and a quickie out on the balcony.
I thought the noise may have come from the harddrive(s), and since I didn't want to make this pulsating noise in my ears any worse by turning the computer on once more using the same setup, I set out to modify my existing hd setup.
First I removed my two ibm drives, one attached to the heatsink (Coolermaster DCD-4001) and put them on the floor for time being.
Then I tried placing the hd with the aluminium heatsink on it in my existing case, no luck, it was too small at the bottom (slide-out motherboard tray took up all the room).
I then turned to my other two cases lying around in my room, of which only one seemed to fit, there was only one problem, there was not enough room with the motherboard still in it. Motherboard out, expansion cards and cables out of the way, I was all set...
First I put in two layers of foam at the bottom for the hd's to rest on, then I opened a backplate for an expansion slot in my computer and then carefully coaxed both my ridiculously long ide cable and my equally ridiculously long 4-pin "y-cable" with three extra connectors through it and in at the back of the other case, connecting both harddrives.
Two extra foam cushions were added at the top and at the front of the case where a 80 mm. fan usually sits, and three fans to keep the drives relatively cool.
I closed up the case, pushed the power button, and hoped for the best.
At first it didn't want to start... and I soon realized why, I had forgotten to put a power connector to my old trusted voodoo 5 (which requires an extra connector for power). All that side, everything worked, quite well.
And while I have attained a slightly worse case of tinnitus, I have also done something to silence my drives (and the resonance they caused), although, a lot sooner than I thought, and a lot more "ghetto".
I've learned my lesson, I won't wait before it's too late the next time...
