Ryck Posted June 6, 2006 Share Posted June 6, 2006 Hi, I'm building a new rig and need to know if either your TWIN2X2048-6400C4 or TWIN2X5400C4 matched pairs will work in the Asus P5WDG2-WS motherboard. But here's the kicker - I want to populate ALL FOUR memory slots for a total of 4gb. I have been Googling around and have gotten the impression that at least the PC6400 RAM will not work in this board if the full 4mb is installed - to the point of being totally unbootable. This may be another case of Asus running their mouths but being unable to back up the capabilities they advertise. I need 4gb for large graphic art projects but want the speed for when I need to kick back and frag stuff all night. Thanks! Rick My rig - the above mentioned mobo, cpu = Pentium 955EE 3.46GHz, RAM = currently two pairs of Corsair TWIN2X1024-5400(or 4x 512), HDD = 2ea 200gb Maxtor SATA2's in RAID 0 config, Optical Drive = Plextor PX716SA DVD+/-R+RW SATA2 Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted June 6, 2006 Corsair Employees Share Posted June 6, 2006 I would suggest Twin2x2048-6400 with this MB and if you use 4 modules or 2 sets of modules I would set the memory voltage to 2.1 Volts. In addition, you will want to use a CPU that is 64 Bit compatible so you can use all of the memory other wise you may only have about 3 gig of ram available in any 32 bit O.S..

Ryck Posted June 6, 2006 Author Share Posted June 6, 2006 Thanks - I'll go with that option. The problems I've heard were with the Asus P5WD2 boards. One other question, though: I don't want to buy both pairs at the same time. Gotta wait to get paid again and again for the second pair. (and talk the wife into it - lol) The machine is currently up and running, so getting a 64bit CPU isn't doable. Will the 6400 RAM still work on a 32bit setup? And yet another question - since there will be a time lag between when I buy the two pairs, will I experience problems if one pair of memory slots has two 1gb, PC6400C4 sticks and I leave the two 512mb, PC5400 sticks for an interrim total of 3gb? I would hope it would just run the RAM at the lower speed until I install the next two PC6400 sticks. My graphics just require quantities of RAM and I think the speed issue is more for gaming(?)

Corsair Employees RAM GUY Posted June 7, 2006 Corsair Employees Share Posted June 7, 2006 Will the 6400 RAM still work on a 32bit setup? A: Yes but you may not see the full 4 gig of memory! Will I experience problems if one pair of memory slots has two 1gb, PC6400C4 sticks and I leave the two 512mb, PC5400 sticks for an interim total of 3gb? A: I would not suggest mixing memory, all of the modules should be the exact same part# and revision for best performance. Link to comment Share on other sites More sharing options...
Dave McKeen Posted August 6, 2007 Share Posted August 6, 2007 I would suggest Twin2x2048-6400 with this MB and if you use 4 modules or 2 sets of modules I would set the memory voltage to 2.1 Volts.

I would like to use two 2GB DIMMs for a total of 4GB in a P5DG2 WS Pro and take the hit of only being able to see around 3GB. Will the TWIN2X4096-6400C5 G do that? It's listed in Memory Configuratior list for the motherboard. I don't want to fill all four DIMM slots because RG said somewhere around here that filling all four slots results in a performance hit from 800MHz to 667MHz. Sorry if any of this is redundant. Thanks, - Dave Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 7, 2007 Corsair Employees Share Posted August 7, 2007 Seeing the full four gig is a MB and or chipset O.S. limitation not a memory limitation. In addition, the MB you have P5WDG2 was rated at DDR667 with a 1066 FSB CPU as I remember but should over clock to DD800 with said CPU. And Yes Twin2x4096-6400C5DHX should run great in that MB with the exceptions I have already listed. Link to comment Share on other sites More sharing options...
