Computer slow after RAM upgrade


Hope u can help me on this one..

I have an Amd athlon 64 3400+ with
3Gb DDR 333 166Mhz. Corsair (TWINX2048-3200C2PT) 400MHz/PC3200 PC Memory non-ECC unbuffered 2-3-3-6 Silver Heat Spreader.
Motherboard Asus K8N-E Deluxe further details of MB are below
4 HDD; 2 Sata and 2 IDE
And I'm running windows XP SP2

However since ive upgraded my memory from 1GB to 3GB , my computer has become very slow.

I don't know if the RAM upgrade has anything to do with it, but it seems like it. Has it started after the upgrade.

It takes ages to shut down. It stays with the blue screen for 20min at least, before eventually shutting down.
Also if i open more than one window it hangs up.
It takes ages to do anything, from opening web browser to explorer windows.
Onlywhen i re-start it works properly for a while before doing it again.

I have read in a few forums that it could be related with the paging file, however i changed the paging file to 4500 (correct me if im wrong, the paging file should be 1.5 times more than the RAM) and it still does not work properly.

Im clueless on how to solve this issue.

Any help is more than gratefull

Thanks in advance.

  1. ok.. this is going back a ways.. but I seem to recall that the 754 socketed A64's had issues with addressing more than 4 'banks' of ram. now I am calling a bank equal to a side of a module here. At my store, we had all sorts of issues relating to memory on them chips if more than 4 sides of ram was installed.

    try dropping down to 4 sides and see what happens..

    That would be 2 double sided, or 1 double and 2 single sided, or 3 single sided modules

    This is a CPU limitation, since the memory controller is on chip, not a mobo problem. a bios update *may* have an effect on this problem now, but didn't back then.
  2. win xp rarely can use over 1-1.5 gig of ram. Take some out and test. 1g at full speed is much better than a 3g problem. Isnt that processor running at 400mhz(200x2)? If so runnning 333 ram is asking for trouble.
  3. Yes, this is a limitation of the socket 754 design. Regardless of the chipset, the system can only handle 4 sides of memory without slowing down.
  4. I have took one memmory module out, but it didnt work out as planned.
    It still takes ages to shut down and still has the same problems as before.
  5. Is there a way of getting around this limitation, maybe with a firmware upgrade??
    I use applications that consume memmory that was the main reason why I bough the extra 2GB
