AMDx5-133ADW Overclocking questions.

Currently I have 99Mhz out of 133 because my board only seems to multiply by 3 instead of the required 4. I have two options I can bump the bus speed to 40 to 120Mhz (a speed I know is stable with my VLB Video Card) or I can bump it to 50 for 150Mhz.

So my question is would bumping it to 50 be reasonable or would it damage the VLB Card, Cache or CPU?

Is there another way to get closer to or slightly above the advertised speed of 133mhz without causing damage?

Also, I know that this CPU is stable at 160mhz because it was tested by the seller before I bought it but without the 4x Multiplier on my Board will it ever be possible to get even close to that without reasonable risk?

If you have experience with this please help me out and leave a comment. Thank you in advance.

Weird Effect on Phone Camera

So. Bad Cache did this to the screen so I went to take a Photo to show a friend and even though I was holding my Camera still it was doing this. So I took a short Video. Any ideas why this was happening? Too strange.

Had this Board I got very cheap as "For Parts". The thing never worked always random Beeping and sometimes nothing at all. It has an Opti Chipset so I didn't give up on it. Random signs of life here and there kept me motivated. Went a little outside my comfort zone and whipped this mod together. Now it's working great and I'm looking for a Case to put it in. So happy.

So, I have a Board. At first it would beep random codes. I soldered pins to the BatCon on the board. It Booted to the BIOS. When I hit F10 to Save or tried to change any settings it would black screen and restart. Another time it booted all the way to detecting IDE/ FDD interfaces and blank screen after a successful Memory Test and POST. Then....nothing. clear CMOS, Battery on or off there's no difference just No BIOS, No Beep. It doesn't even initialize the Video Card. Nothing. So I went down the path of modifying my RTC to add a new Coin Cell (The RTC was tested with a multimeter and showed 2.8Volts. dead.)

Then it occurred to me.....why do I have two batteries? Even without the RTC Battery I should see some sort life from the BIOS no? Did I somehow corrupt the BIOS by resetting CMOS pins with both Batteries dead / removed?

Can it be saved?

Picked this up for $25.00 at a Thrift Shop. Worth about $16,000.00 CAD at the time of release (adjusted for inflation) in 1989. Beautiful Amber Monochrome Display. 16mhz 386 with 1MB of RAM and a 40 MB Hard drive. Allows full sized ISA Expansion Cards. Cool handle for lugging it around. This one still has the original Conner Hard Drive (working). In pristine condition. Used in a Laboratory or Hospital based on the Software that was installed on it. Lucky find. Only had a faulty Power Switch and a bad battery so far. Installed DOS 6.22 with Norton Commander Shell.
