Is there something wrong w/ the DDR RAM?

[TimeKeeper]

Recently, I have encounter many issues w/ RAM on many different system.

Crucial "Micron-chip" PC2100
PNY "Infenion-chip" PC2100

I have tried them individually w/ both AMD and P4 system. Seems both having stability problem, that may cause radom reboot.
(I run them at 133FSB ONLY)

Then I purchase PNY "Samsung-chip" PC2100, the problem never appear again.
I tried the CC's generic brand "Nanya-Singarpore-chip" PC2100 , it appear to be more responsive.

Is it me or it seems the "name brand" chip maker has some problem? Or is it just issue w/ some mobo I am using?

p.s. I did not change any setting while I swtiching around the RAM.

I haven't seen any issues with my Crucial DDR2100 in either of my mobo's. Wonder if you ran both of those chips through a mobo with a bad regulator on the Vdimm line and managed to damage both of them (both are lifetime warranty, which you should utilize).

Matter of fact I am running my Crucial DDR2100 at 362.5mhz right now.

Argh....possible cause, thanks.

Now I might have to figure out which mobo is to blame!
Also, PNY (infenion-chip) does NOT respond to 166FSB on my P4 system, while both PNY (samsung-chip) and CC (Nanya-chip) run without the problem.

Is this possible?

Does upping your Vdimm (from 2.5 to say 2.7) make any difference whether it will run or not?

Unfortunately, the mobo has not Vram tweak.

It could very well be a motherboard problem.
