P4P800-D + 4 256mb mem sticks question = read please
Hi, i've just bought an asus p4p800-d + p4 3.0C HT 800 + winxp and all works
fine, though i have a question about my memory. i have 2 of these kits : Dual Channel Optimized DDR Kits - EL Platinum Edition 512MB (256MBx2) PC3200 DDR400 CAS2 (OCZ400512ELDCPE-K) http://www.ocztechnology.com/product...annel+Platinum = total = 1g now if i install just 1 pair [for 512kb], doesn't matter which into the 1st 2 blue slots, i can see the message on bootup saying " dual channel 400 mhz" = so this is ok + i can turn the asus memory accel on with no problems and a nice memory read increase according to aida32, something north of 4500 if i remember correctly, the write stays about the same with or without the memory bios boost. Now when i populate all 4 memory slots with the 2 kits [1g] on boot up i see =" dual channel 266 mhz" !!!! what happened to my 400 mhz????? + when i try to enable the asus memory accel it says it can't boot and i have to disable it ???? Why is this happening when i use all 4 memory sticks? Anybody have similiar exp? thanks ps. it's not a huge big deal, the write test is about the same speed as just the 2 memory sticks themselves but the read test is just shy of 4000 if remember correctly. I'm thinking i should have just bought the 2 512kb kit and they would have worked at 400 = the memory boost, seems like the p4p800 is real picky when you populate all 4 |

This is the response i got from OCZ support = makes sense to =
Hi, Based on our experience, usually installing more than 2 modules will cause system performance drop no matter what Intel based chipset motherboards you use. P4P800 is even pickier than other boards. So we can only guarantee one pair load. Do you think if it is possible to exchange your 4 x 256MB to 2 x 512MB PC3200 with your vendor? I think it is the best approach to solve your current issue. If there is anything else we can help you, please feel free to let us know.

You should have used (2) 512MB sticks. It's much more stable in that board,
and boards in general. -- DaveW "harry" wrote in message news Hi, i've just bought an asus p4p800-d + p4 3.0C HT 800 + winxp and all works fine, though i have a question about my memory. i have 2 of these kits : Dual Channel Optimized DDR Kits - EL Platinum Edition 512MB (256MBx2) PC3200 DDR400 CAS2 (OCZ400512ELDCPE-K) http://www.ocztechnology.com/product...annel+Platinum = total = 1g now if i install just 1 pair [for 512kb], doesn't matter which into the 1st 2 blue slots, i can see the message on bootup saying " dual channel 400 mhz" = so this is ok + i can turn the asus memory accel on with no problems and a nice memory read increase according to aida32, something north of 4500 if i remember correctly, the write stays about the same with or without the memory bios boost.

it's VERY stable now with my 4 256 sticks but i just lose alittle on the
performance as opposed to 2 512 sticks "DaveW" wrote in message news:JxrEb.597348$Fm2.546178@attbi_s04... You should have used (2) 512MB sticks.

Go for the 2 x 512 if you can - you have an upgrade path if you need one &
it will work. - Tim "harry" wrote in message .cable.rogers.com... it's VERY stable now with my 4 256 sticks but i just lose alittle on the performance as opposed to 2 512 sticks "DaveW" wrote in message news:JxrEb.597348$Fm2.546178@attbi_s04...

I have 4 256 meg sticks in my system and I just changed the auto sensing of
the DDR speed to 400Mhz (like yours mine was not sensing 4 sticks properly.) Mine figured they were 320Mhz. I just cranked it up to 400Mhz and all is well, no instability at all...
