Intel DP35DP and Corsair TWIN2X2048-6400C5DHX


Recommended Posts

Hi there! i'm a new member, My name is Marco i'm from Italy.... Nice too meet you:)))


I bought Corsair RAM DDR2 "TWIN2X2048-6400C5DHX" and i had problems With my Motherboard Intel DP35DP.


When i power on, i got 3 long Beep as if the RAM is not present.


I Tried to mount to another Mobo (P5AD2-E Premium) and it Work Perfectly.


Also I tried to mount only one module on a single on the 4 slot, but i got the 3 beeps anyhow.


I was aware that DP35DP supports only 800mhz Cas 5.5.5 and 667 Cas 5.5.5. infact i chose TWIN2X2048-6400C5DHX for a full compatibility.


I think perhaps that the motherboard is broken?


There is some member that use Intel DP35DP with TWIN2X2048-6400C5DHX with no Problems???


Thank you




Sorry my English not very fair :)

Yes, i have 2 module ddr2 667mhz cas 4.4.4, but it still doesn't start


The DP35DP only supports 5.5.5 at DDR2-667 speed. In addition, the Corsair modules may use an SPD which does not work well with any motherboard which adheres strictly to the JEDEC specs even if the timings programmed into that SPD is supported by the motherboard.

Any updates from INTEL???? I have the same board.. but different ram and i want to get XMS2 DOMINATOR to run in DUAL CHANNEL??? Is it possible?


Sorry, but you're out of luck at this time. None of the mid-range Intel-branded desktop motherboards have any provision at all whatsoever to manually set the DIMM voltage; Intel-branded mid-range motherboards permanently lock their DIMM voltage at 1.8V. And your Dominators require at least 2.1V in order to run at their advertised timings. And none of Intel's own DDR2 motherboards support memory speeds above DDR2-800 (PC2-6400) to begin with.


As a result, you can try running your Dominators at the JEDEC-standard speed, timings and voltage (DDR2-800 speed, 5-5-5-18 timings and 1.8V) - but there is no guarantee that your system will run reliably with those memory modules. In fact, memory errors, system lock-ups and program crashes can occur more frequently if you run your memory modules at too low of a speed than if you run them at their nominal tested speed.
