Ram is not compatible?

[ROEHUNTER]

I just upgraded from a Nforce 1 board to a MSI 6741. I had 2 Centon 512 PC 2700 chips in my old board . I can not get them to work in the new board and I have tried everything. They worked just fine in the old board. I had to put my old 2 PC 2100 256 chips in to get it working. I can due with 512 but it makes me frustrated that I cant use my gig of ram. I have tried changing everything I could find in the BIOS unless I am missing something. Any ideas?

maybe your motherboard doesnt support those sticks of ram?

I thought of that , but the part number on the ram is what the Centon site calls for it .

Ok I finally found some time to mess with my RAM . I tried every setting in the bios that I could think of and more . Nothin would let my 2 512 sticks work. I realized there was one thing I didnt try and that was putting 1 of the 512 with one of the 256 . Well oddly enough this is working at the moment so at least I have 768 instead of just 512. I just wish I could get both 512 sticks working.

A thought..

What is BIOS setting for ram. "Auto" ?

If so, your ram might be trying to run at 166mhz. Maybe too fast for the rest of the system.

I mention this because, with the PC2100 in there, the PC2700 is going to revert back to the slower speed of the PC2100 stick. That is from 166mhz -> 133mhz

Try setting ram at 133mhz with "Optimal" settings for timing and try it again.

Might also note the timing used (in BIOS) while the pc2100 is in there. Apparantly the PC2700 like those just fine too.

Yes I will give that a try Thanks!

I put the limit on the DRAM clock to 266 Mhz instead of 333 Mhz and everything seems to be working fine now. Thanks for all the help.

Not the first time that DIMMs showed less capable than their sticker suggested ... after moving them to a higher performing platform. Remember the numerous rants when everyone moved their SDRAM DIMMs from socket-7 or pentium-III to Athlon? Same thing. History repeating

Good point.
