Why does DDR1 work but not DDR2?

[soarwitheagles]

Hi everyone,

I put together a system about 3 months ago and it works excellent. I installed PQI's DDR1 3200 duals. Two sticks at 512 MB each so that is a total of 1 gig.

My mother board is the ECS P4M800PRO-M. I recently attempted to upgrade to DDR 2 with 2 gigs. But each time I attempted to use the new DDR2 ram, one of my programs will not work.

My video card seemed to freak out at times as well.

The reason I wanted to go from 1 gig to 2 gigs is because I installed a TV tuner card and I would like to record some programs.

Here are my questions:

1. Why do some of my programs not work when I am using the DDR2 sticks?

2. I seemed to experience a noticable difference in the increase of speed when I updated from DDR 1 with 1 Gig to DDR 2 with 2 gigs! Is there really that much of a difference and do I really need the 2 gigs to do TV tuner recording?

3. Even though I returned the Kingston DDR2 2 gigs to Fry's, and tried a new package of them, the same issues arose. Is is possible the slot on my mother board is the issue and how can I test the DDR2 slots?

4. Any other ideas or thoughts? [please do not say get a life by getting a real MOBO. I have been unemployed and I barely was able to build this system even after waiting 10 months and buying only ad items from FRY's.].

Ok, hope someone can help me!

ddr1 and ddr2 are different standards they are not compatible in any shape or form either your mobo is old and supports ddr or your motherboard is nw and supports ddr2

Hey....,,, nothing wrong with a ECS MOBO!

 

[soarwitheagles]

Salty,

The ECS MOBO I purchased at FRY's is capable of using either DDR1 or DDR2, but not both at the same time.

Thanks anyway,

I wish there was someone out there that could help me understand what to do!

 

[saltynay]

the two cards are incompatible it won't physically fit i the slot as the notches are in different places!!!

I see the board can take both types(ddr and ddr2) but only ddr2 533

what speed ddr2 did you try?

 

[fastrandstrongr]

lol... salty, the board takes BOTH. it has two different types of slots.

although i doubt that the speed of the ram makes a difference, since the mobo would just clock down to 533, i would still try it. more than likely, one of your slots is bad. i once had an ecs mobo (rs400a) that supported both ddr1 and ddr2, and one of its ddr2 slots was bad as well...

 

[Poizen22]

see your mobo cant be that bad it has technology some of use techies arent even aware about lol

 

[peterhuang913]

Ok this has to stop.
Listen up, noobie . I have an ECS mobo. It has both the ddr and ddr2 standards.
The slots look like this:
[ddr][drr][ddr2][ddr2]
The memory controller only boots on ONE type of memory at a time, so you cant run ddr and ddr2 at the same time

i once had an ecs mobo (rs400a)

lucky me, i STILL have it

 

[darksideleader]

i have a similar mobo, but for SDRAM and DDR, ECS K7S5A mobo, pretty good for its $50 value at its time.

Same for me i could never get the faster ram to work, SDRAM would work awesome but when i put in DDR 266 ram (alone)it wouldn't work. I'm pretty sure the all ECS with this type of feature are faulty.
