Urgent Ram Help! - Asap

[itmaster007]

HI,

I Have just bought some new RAM for my PC and I have checked it is all compliant. Any way, I installed it and I get no Video output and just kep hearing looping beeps. I have upgraded from 2 PC400 DDR DIMM 512Mb Ram modules to 2 PC333 DDR DIMM 1024Mb Ram. (the board only holds up to 2GB!)

Anyway, I really need to know a solution, I thought possivly a lack of power being supplied from the PSU? What do you think?

And if you're still stumped, and post back, please leave some system specs like mobo CPU etc.

One other item the article doesn't mention is that there may be a problem with the RAM itself. To test if you have a stick of bad RAM, turn the computer off and remove one stick and then reboot. If that doesn't work, turn the computer off, reinstall that stick and remove the other stick and try again. Just remember to place the single stick into the first DIMM slot. Regardless if that works or not, downgrading from 400 mhz to 333 mhz will slow the system down a little.

test ram with memtest 86+ booted from a floppy or cd for at least 7 passes.

hi lawrence!!!
sorry to hear about yr ram problem, i have a pretty good idea of what your problem is, you say your old RAM was pc3200, and your new RAM is pc2700, well for instance my motherboard needs to have pc3200 which is stated in the motherboard manual. Maybe your motherboard needs to have the fastest type of ddr RAM, go back to maplins and order some pc3200 and you might just find your problem is solved.

 

[itmaster007]

true

agreed robin - however my mobo manual states it is compatible with all three types!

If you give more detailed specs we might be able to help a bit more. It could be that your CPU's FSB is linked to the memory speed & requires PC3200 / 400 memory (as opposed to PC2700 / 333) to be able to function properly.

 

[Robin997]

i agree with Didou, that could well be your root problem.

re-set your bios
if that does not work make sure its unplugged from wall
pull battery put back in
should be a button or jumpers to re-set CMOS/BIOS
forgot to say
Welcome to Techspot

post your system specs would help
ram value about the same unless it was free

 

[Tedster]

not necessarily. You new clock speed is slower. Don't mix ram types either.

If it worked well at PC400, why buy PC333 ? You need PC400

You've given every possible information except the name/model of the motherboard. It would help if we could download the manual & see what it says concerning memory support.

check for latest bios may need to flash newer version
if my advice above has not helped
the MB manufacturer should have a list of memory thats been tested to work
there's sometimes an issue with cpu's and fsb speeds only using certain memory speeds
if all that can be used is 800FSB processors I don't think thats an issue
on the other hand if it can accept a 533FSb processor than it could be that 333 memory only works when that lower FSB processor is present
after all said it may be the memory is bad or you did something on remove and install to damage ,have you put the 400 back in and system will boot again
