Unable to overclock 1700+

First, I have a question. Did AMD make XP CPU's with the ceramic ummm... I dunno what you call it, can't think of the name... instead of the organic (redish) type? Because I have an XP1700 CPU, and it looks identical to my T-Bird 1.2 except of course for what it says on the core.
I'm sure my L1 bridges are open (locked) because I tried adjust the multiplyer in the BIOS and it wouldn't change.
I'm using a Shuttle AK31 motherboard, and PC2100 DDR RAM... 2 256 mb modules for a total of 512 mb. I also have a Gainward GeForce4 Ultra 650/XP Golden Sample card. I experienced lockups when playing games and traced it back to the CPU's voltage. IT was at 1.690, and spec is 1.750... so I increased it by .050 and now it's stable, when I watch the voltage in the BIOS it seems tso fluctuate between 1.740 and 1.760, is that normal for it to fluctuate?
I have the video card clocked to it's enhanced mode, which is 260 MHz on the GPU, and 520 for the RAM from the 250/444 stock setting.
All my attempts to overclock my CPU have left me unstable. I tried a 139 MHz bus to get it to 1.53 Ghz and it boots and the BIOS displays 1800+ but it locks up when playing games. I'm a little hesitant to increase the voltage of the CPU any more. I know some of you are using 1.800 volts or more... but, I'm hesitant to do that because I've never messed with voltages before. I know increasing the BUS is more beneficial than the multiplyer because it increases the speed of everything, not just the CPU. Could that be the reason it's becoming unstable? Maybe my video card doesn't like it? Or my RAM? I have adequate cooling... the CPU never runs over 135 degrees F even under full load. At idle it's at 120 degrees F and the case temp is at 90 degrees F. I'd really appreciate any suggestions anyone can offer.
Would hoping for XP 2000+ speeds be too much? I'm curious, those of you who have an overclocked XP1700, what speed are you currently running at?
Another question. Why couldn't you take an XP 1600 and overclock it to the speed of a XP 2200 by adjusting the multiplyer? Are the CPU's themselves physically different?

Almost forgot... I'm using an Antec 350 watt ATX12V power supply. I have a Seagate 7200 RPM hard drive, a CDRW drive, a DVD drive, Soundblaster 16 PCI sound card, and a 10/100 card. Along with the RAM and video card I mentioned already.

My XP1700 overclocks to xp1900 speeds fine. I run the voltage at 1.775 and the fsb at 147. It runs at 152fsb(xp2000 speeds), but my memory miscounts. I run at 300w ps and soltek sl-75drv5 with 512 ddr333 memory. I didn't unlock the cpu.
