View Full Version : A Memory problem

When i built my computer over a year ago, i went with 2 sticks of 512 corsair pc 3200 (400 MHz) memory. This past christmas, i decided to get another 2 sticks of 512 memory. i consulted my newegg order history, and got 2 of the EXACT SAME sticks (for dual-channel preserving purposes). However, now my memory is running at 300 instead of 400, and the only way to change it is to force override it--and whenever i do that, my computer doesn't turn on... i have to reset my bios by taking out the jumper in order for it to work again. Any ideas? help would be hugely appreciated.

... since no one else is responding:
I just added 2 512's of DDR3200 to my system that was running DDR3200 at 400. Now it runs at 300. I was pissed, but further research showed that there's no "real-world" noticeable difference running at 300 instead of 400. I *think* I read that any time you use 4 sticks, the timing slows down (but as I said, I don't know what the sh!t I'm talking about!).
Good luck!

Hmmm.. I'll try to help you. what are your ram timings at? I added 1 more gig (2 512 sticks) so now i have 2 gig. When I put th extra ram in, the computer beeped with a ram error. So I changed the settings in the bios to 2t. Now my ram runs fine at 400. Check your bios for ram timings.

what exactly do you mean by ram timings? and 2t? i just went into my bios and what it showed was as follows:

SDRAM tCL: 2.5
SDRAM tRCD: 3
SDRAM tRP: 3
SDRAM tRASmin: 7

Memory Refresh Cycle Time: 12 clocks
Memory R/W Delay: 2 clocks
Memory R/W timing: 6 clocks

Hello mate,

You should be able to run 4 DIMMS on a P4 MoBo with no worries about dropping to either 2T or DDR333.

Have you tried the new memory on its own to be sure its not faulty in itself??

i haven't tried the new memory by itself, but i don't believe it's faulty, because my computer has worked fine with the memory in it, except of course the fact that it's underclocked. what exactly does 2t mean?

2T is the command rate - you should be able to run 1T with no problems......

is your MoBo BIOS upto date.

Do you have your CPU overclocked? If so, try going back to stock speed and try there to place the RAM at 400. It may be that with the 4 modules there is some unstability issue that rpevents them to work without the 5:4 divider... if at stock speed it's ok try OCing again to a lower speed until it fails again to find the limit.

About the 1T/2T, as far as I know, Intel CPUs and boards don't have the option to choose or see it, so don't worry.

not true, all my Intel boards have had the option.

but what's the difference between 1t and 2t? can someone elaborate for this noob?

Make sure that your motherboard has been flashed with the latest bios. Asus board didn't support dual channel ram in all four slots until I got the latest bios update.

On a similar note, my buddy did the same thing with adding another gig of ram to his rig. Now, after gaming for about 3 or 4 hours, his whole system starts to slow down...so bad that he has to exit the game. Once exiting the game, he has to wait a long time for any program to open up. It sounds like a ram issue...anyone got any ideas? (sorry, not meaning to hijack this thread)
