300a at 504 with 2.2v. Success. Here's How
I just got my Retail 300a working stable at 504 with 2.2 volts.
My Motherboard is Abit BH6, Ram is PC100 (no-name)128MB, my gfx card is a PCI Voodoo Banshee.
This chip ran fine at 464 with 2.0v with no additional cooling.
To get 504 I removed the original Intel Heatsink and fan and replaced it with a larger better one, NOT a converted PII heatsink, just a celeron heatsink.
I then mounted the original intel fan(built into a black plastic cover that goes over the whole chip) on the back, secured with 6 elastic bands!! It was an idea i had seen on a web site a few weeks ago and I decided to copy it.
I also have a 486 fan attatched to the original heatsink of the Voodoo Banshee card and I have a P Pro fan blowing over the gfx card to force the hot air out of the back of the computer through an open empty slot.
My sound card is an AWE64 PCI.
So that's a new heatsink and fan, the original fan on the back (celery sandwich, fan on the gfx card and a fan removing the hot air from the case.
No Extra holes in the case.
It works Worth a try.
I'll post the details of the chip here tomorrow (week, Malay/Costa R. etc)
Those elastic bands won't last forever. You might consider Nylon tie-wraps or something else more enduring.
Forgot where I read it, cooling the back of the chip makes even lousy chips (COMPEQ) overclockable.
Your solution if rubber bands seems strange. I thought everything in the whole world could be fixed with duct tape. :-)
