Intel Desktop Board D865PERL Memory Upgrade Problem!! URGENT!!

Hi Experts,

I am using Intel D865PERL as my motherboard with P4 3.0G CPU, and Kingston 512mb DDR 400Mhz x 2

I just bought another two 512 ram today which are Veritech 512mb DDR 400Mhz 2.6V.. after i installed these two new rams on the empty ram slots,  i couldn't boot my machine ... it's a blank/black screen showing nothing. .. but if i pulled out two new rams, then the machines can be booted normally again...

intel website says this motherboard can support up to 4GB ...  so i think it shouldn't be a problem here
and they are all 512mb DDR ram with 400Mhz... i am wondering where goes wrong...

Thanks.

If you have different latencies for the RAM and have specified to use the SPD to set the speeds automatically, it may be trying to run one pair faster than it is rated.  Try setting the latencies manually to the slower of the pairs.

hi callandor,


thank you for your fast feedback...

but sorry i am not quite a computer hardware savvy...    

how to set the latencies manually to the slower of the pairs? and also how to find out which pairs are the slower?

thanks

Run Everest with each pair separately and see what it says about the memory.  Post the details here.

could this be the problem?  if so, is there any way to install rams in different frequency in the same pc?

CallandorCommented:
200MHz is ok - the motherboard FSB is being reported, and the DDR makes this an effective 400MHz.  Your Kingston RAM is rated at 3-3-3-8, which is fairly slow.  What are the readings for the Veritech?  Swap out the Kingston modules and install them.

The memory timings are the same, so you can try manually setting the memory timings to 3-3-3-8.  Are you installing these as dual channel, as described on p.34 of ftp://download.intel.com/support/motherboards/desktop/d865perl/rl_English.pdf ?  Try loading BIOS defaults, and then installing the new RAM.  If that doesn't work, try relaxing the timings even more, to 3.5-3-3-8.  Since you can't boot with all modules in, you will have to make the changes with only one pair, shutdown, and try installing the other pair.

hi callandor, thank you for your suggestion, i will give it a try now,

just two questions...

first, i want to install them as dual channel, so should i put 2 kingston ram into Channel A and B's DIMM 0 position, and 2 veritech ram into Channel A & B's DIMM 1 position?

second, how to set the time to 3.5-3-3-3 ?

many thanks!!

CallandorCommented:
Yes, you have the correct way to install them as dual-channel.

I couldn't see a way to set the RAM timings manually for this motherboard, so you can try installing both sets of RAM and resetting the BIOS (move the CMOS jumper from the Normal position to Clear, and then back).

hi callandor,

i tried to reset the BIOS, but still didn't work :(

also, i found some options in BIOS setting.. not sure if thats what you mentioned above?

iin the chipset setting,

there is:  Burn In Mode
              Chipset memory timing control
                -> SDRAM Frequency :Auto
               -> SDRAM Override: Auto
               -> SDRAM Timing Control : Auto
               -> SD RAM RAD ACt. Pre: 8
               -> SDRAM# Latency: 3.0
              -> SDRAM RAS# to CAS# delay: 3
             -> SDRAM RAS# Precharge: 3
0
 
CallandorCommented:
That's the place to make changes - try setting SDRAM# Latency to 3.5 or 4.0, and if that's not good, change the other 3 values to 4.

Hi Callandor,

Thank you for your excellent answer!! after i changed the setting in BIOS, now it works fine !! =)
