memory mix : did I make something wrong ?

Hi

 

I've bought 2 Corsair VS1GB400C3 of 1GB each. There were added to 2 other old Noname memory of 512 MB each.

Now My PC has 3 GB of RAM memory and it works.

 

At POST the bios says I have DDR333. Before adding the Corsair memory, it said DDR400.

 

Sisandra says this : (sorry, it's in french)

Banques de Mémoire Logique/Chipset

Banque 0 : 1Go DDR 3.0-3-3-7 2-10-3-1 2T

Banque 1 : 1Go DDR 3.0-3-3-7 2-10-3-1 2T

Banque 2 : 512Mo DDR 3.0-3-3-7 2-10-3-1 2T

Banque 3 : 512Mo DDR 3.0-3-3-7 2-10-3-1 2T

Module de Mémoire : Corsair VS1GB400C3 1Go DDR PC3200U DDR-200 (3-3-3-8 2-11-0-0)

Module de Mémoire : Corsair VS1GB400C3 1Go DDR PC3200U DDR-200 (3-3-3-8 2-11-0-0)

Module de Mémoire : FF 512Mo DDR PC3200U DDR-200 (3-4-4-8 2-0-0-0)

Module de Mémoire : FF 512Mo DDR PC3200U DDR-200 (3-4-4-8 2-0-0-0)

 

My three questions

1. Is my PC slower with the four memory than the old two Noname ?

 

2. If I replace the old noname memory by the same Corsair VS1GB400C3, what will be the speed of my PC compared with the old two Noname ?

 

3. Is there something I can do on the bios to accelerate the PC ?

 

Thanks for your help

Thanks for your answer

 

Now the speed of my Memory is slowest than previously. Is it (400-333)/400=-16.75 % ?

 

Have you some suggestion to parameter the overclocking of this association of different memories ?

Since you're maxing out the slots, using different size memory as well as memory from different manufacturers, there's no guarantee of compatibility, let alone stability or overclocking. Personally if it's stable I'd be grateful for that. You can try overclocking it, but I doubt it'll OC much, if at all.

Do you think I whould replace my two old noname by the same Corsair I just bought ?

 

If I do, Will I see a difference of a speed ?

 

Or If 2 GB is enough for most of my applications (except may be DXO Optics), the better is to remove the old Memory to let only the Corsair modules ?

 

Thanks for you answers and sorry for my poor english :)

Hello,

remember you have a 32 bit OS and it will only see 3 1/2 gig of ram max.

with that in mind, if i may toss in my 2¢

if it was my rig i would either get 2 kits of TWINX2048-3200C2PT and clock it down to 333 but overclock the CPU to balance out. i'd bump up the RAM volts .1 if needed but thats me Mr. Voids Warrantees, i suppose you could get another 2 gig kit of the VS you just bought and try the same thing. the CAS2 TWINX just has a better reputation in my nforce boards.

 

anyway, thats my 2¢, if you fill all 4 slots you will likely have to clock it down to 333.

the loss can easily be made up for with a bit of CPU tweaking but thats for another forum.

or just try 3 gig and leave it at DDR400 and see what happens, whats half a gig anyway ;)

 

Good luck!
