Better Overclocking 512mb ddr ram ?? Mushkin , Crucial or Corsair ?

[kulki]

can someone plz help me out here. I am building a system for the heck of it. But I only use my puter for surfing the internet period.
Now I cant decide between generic 2100 and Micron 2100
The difference between them is 57 as opposed to 68. Is there going to be a significant difference in the quality between these two memories and their performance. Also I am hoping to OC to like 140fsb will any of these memories give a problem on a 1:1 ratio setting?

Could anyone tell where I can find some material explaining about memory. I want to know what is the difference between a
PC2100 and PC2700 or between 5ns and 6ns, etc. I'm complete ignorant about this matter.

Tks.

How can you tell when the limit you hit from overclocking is due to the CPU or RAM? I have a 1.6A overclocked completely stable with a 155 MHz bus and 1:1 bus to memory ratio on an ASUS P4B266. At 155, I can set the BIOS RAM settings to the fastest (2-2-2-6 or whatever, Turbo 2) and be fine. At 156, I can't boot with Turbo 2, but can with "Normal." From 156 to 160 MHz bus, the computer will boot and be ok in Windows XP for 10+ minutes, then XP will blue screen, write RAM to the hard drive, and reboot. Is this indicative of the CPU causing errors?

BTW, my RAM is a 512 MB DDR stick from Crucial, but I forgot to check what chips it has.
EDIT: I just checked the chips - they're Samsung.

Possum - at 155 1:1 you're at 310Mhz on your 266Mhz Crucial RAM. I've got the same RAM (but with Infineon chips, not Samsung) and the most I can get out of it on my P4B266 is around 305Mhz before I get problems. That's probably all you're going to get out of it.

I just went to Konmax (they're about 5 minutes from where I live) and bought 2 x 256 sticks of Kingmax PC2700 RAm. The chips say "-05" on them. I hope this is 5ns.

I also called Kingmax tech support and they said ALL their DDR333 RAM is 5ns. They claim they don't make anything else.

(sorry for double posting, but...) Check out this Tweak Town review of Kingmax DDR333: they say it's 4ns in the chart, but on the close up pic at the very bottom of the page, you can clearly see "-06" on the chips:

Bummer, I want a 512 stick.

same here, I just want a single stick of 512mB DDR333 (kingmax 5ns ram would be really good) and add another 512mB when the price drops. Most mother board have a note that only 2 slots can be used if running DDR2700. I believe this can also be found on the SIS645 chipset review.
