Is this a good oveclock?

You did good job.
Check this out and see the case of Test 4 - 150/225 timings 2.5,2,2,6,1t DDR450 4:6 ratio.

He reached DDR450 with SAMSUNG PC2700 and ASUS P4S333.

CPU speed is good.. but your memory can go much higher... MUCH higher.. 166MHz atleast.. so I would say it's not a good memory OC.. but your CPU is very good..

What do you mean it can reach 166mhz? its running at 211mhz. For some reason i cant push the cpu any higher than 142fsb and 4:6 divider. Even at 2.9v and decreased timings, the ram just wont go higher. 2.9v got 1mhz more that 2.7v. Did i get crap ram?
But when i go to the next memory divider down, i can hit much higher cpu fsb.

ok.. When I mean your memory should be able to hit 166MHz bus speed, that's 166MHz bus speed for the memory.. but since it's DDR that means it's running a 333MHz.. And you P4 bus speed which is quad pumped would be 666MHz.. now your CPU maybe limiting your overclock. But I will tell you this.. if you memory is topping out a 142MHz.. well then it's crap.. because even my PC2100 can hit 176MHz.. and more questions just ask...

And you don't need 2.9v for your memory.. or even 2.8v... 2.7v should be more than enough.. try increasing your CPU voltage..

zck250 is right. P4S533 is a little different with your P4B266.
It has 4:6 mem ratio, so FSB 142 means that 142/4*6 = 213 and double rate 426 MHz for memory.
That means if zck250 hit FSB 166, Quadpumped CPU is 666 MHz and also if he use 4:6 mem ratio, 166/4*6=250 and double rate DDR500 (<-- He may need DDR400 with 2.9V to reach it).
