Ok, I’m betting there’s a fluke in your ram or in the BIOS and it’s not handling the speed of the new ram..Time to contact Dell….Hope you speak East Indian Swahili?:)))) or whatever the heck they speak…suuuuure aint English?:)) Funny how they speak English till you pay for it then they switch to a foreign language? hmmm Good luck, Bruce From: computertalkshop-bounce@xxxxxxxxxxxxx [mailto:computertalkshop-bounce@xxxxxxxxxxxxx] On Behalf Of CRAZYDOVE@xxxxxxx Sent: Tuesday, September 08, 2009 3:56 PM To: computertalkshop@xxxxxxxxxxxxx Subject: [CTS] Re: another ram question.. Thanks Bruce..I will try that...and I will also check the bios..see if I missed something. I originally had them in slots 1 and 3..but the clips are colored white for slots 1 and 2 and black for slots 3 and 4..and the original ram was in the two white clipped slots. AND I took out the original ram..and put it away. I'm only using the two new sticks. I understand for one thing, the ram will only run as fast as the slowest ram ie:667..plus...I bought 4 gigs..didn't think I'd need 5..LOL SO..it's new ram, old ram went bye bye.

Try this.. take out stick one from its current location.. replace it with stick 2…..Run the PC….if no problems, install stick 1 to where stick 2 used to be… if you run into issues….. it may be the 2 sticks are meant to run in pairs( my feeble mind forgets the hi tech mumbo jumbo term?) someone will correct me tho.:)) … look at your manual to see? Possibly you need to put 1 stick in slot1 and one in slot3 to make them match. Plus there’s always a chance you got a bum stick of ram in the mix.. Contact Dell and see if they’ll replace the ram with 2 new ones for you… Plus there’s always a chance you need to make a change in the BIOS for the higher speed or (matched pairs) stuff.. Usually the BIOS handles that automatically tho? And just cuz your BIOS ‘sees’ the ram doesn’t have to mean everything is hunky dory? HTH Bruce _____
