is Kingston and PNY ram good for overclock?

[stso]

I have one kingston pc133 and one pny pc133 cas3 memory ... do you guys think it is good for overclocking?
I was trying to OC my duron 850 on my kk266, but when I set the FSB to 125+ the system won't even post .... might be the memory problem ... Is there any way I can tell this is a memory problem?

Also, my system is not very stable, it never pass the quake3 loop test at regular speed 850mhz ....
I ran the quake3 loop program before I go to bed, when I wake up, there's NOTHING on the screen ... black screen, no matter what I press on the keyboard it just won't show anything. I have tried this several times, but no solution yet. Ram problem?

forgot to mention the temperature is low ... only 42 degree celsius when I run quake 3 ....

Thanks in advance

I personally never had a problem with either of these brands RAM. The problem may be with your Video card. Try just 1 stick of ram at a time. Will it run stable without any overclock?

what chips are on them? I've bought both of them and they were infineon chips and were able to overclock at pc133 cas2

I run Kingston 256 MB PC100 with a PIII 533 (133 FSB) and experience no problems. Has Samsung chips on the module.

Heard the Winbond chips on some Kingston modules have issues when overclocking.

Also agree that Kingston with Infineon overclocks very well.
