Can you upgrade procesor or ad ram to an asus x501u

SOURCE: RAM

Hi, I checked your computer out, and you can install 4GB of DDR2 laptop RAM, upto a max speed of 667MHz.

You have two slots, so you can do this via two x 2GB DDR2 667MHz sodimms. I choose Kingston, as it seems to be the most compatible that I've seen so far.

However, you are likely using a 32bit operating system, so despite fitting 4GB of RAM, Windows may only indicte 3.25GB, or 3.5GB, or thereabouts, due to the fact that a 32bit operating system cannot address more than 4GB of memory addresses. This will not be a problem, and the extra memory will still add to performance.

Though I also suggest that you disable unnecessary Vista processes to make your computer much faster again.

See www.speedyvista.com for a list of what proceses you can, and cannot disable.

Regards,

Erik.

Make sure you remove the battery before removing or inserting the ram :)

No worries about it not being dual channel as most laptop arent.

DDr (double data rate) ram runs at 200MHz but is actually 400 one the double data rate is applied so they are one and the same :)

I hope its a sodimm stick of ram that you bought? They are about 3i inches long rather than 6 like desktop ram?

I had the same problem and ASUS tech support was of no help. I did however find the culpret in the BIOS setup. Go to Advanced, Chipset, NorthBridge Chipset, and Memory Configuration. Set the Bank Interleaving to Disabled and save the settings. Check these settings also while you are there:
Channel Interleaving = Auto
Enable clock to all DIMMS = Disabled
Memory Tristate = Disabled
Memory Hole = Enabled
Unganged Mode = Enabled
Power Down Enable = Enabled
Power Down Mode = Channel

Roger,

The problem clearly isn't a video sharing as I was originally suspecting.
First let me inform you that even your upgrades are several generations behind the current mainstream, Not a problem as long as they are sufficient for your needs. I don't know about the CPU but the Video card is no longer supported by ATI.

Ok lets get down to the Nitty Gritty

First lets remove ALL of your cards from the PC
Video card, any PCI cards and if you have them even the ISA cards
Now remove the ram modules and the CPU

OK we should be starting with a bare Motherboard
Check to make sure that all of the power connections are attached in this case it should be a single 20 pin ATX connector

With that done make sure the IDE connectors are oriented properly there is a notch on the drives connectors that lines up with a key on the ribbon cable.

make sure this cable fully seats into the Motherboard and the drives connector(Try to route the cables so that they are tucked out of the way if possible)

Now repeat the procedure with the floppy drives ribbon cable and connector (If applicable)

Inspect the CPU make sure the heatsink and Fan are attached and mounted Flush to the CPU card
Now insert the CPU into the Slot1 making sure to pay attention to orientation. If I read right you replaced the processor with one of the same speed? if so you don't need to mess with the jumpers that are onboard for the CPU.

If it DOES need a different FSB setting the open up the user manual(Link below if you no longer have it) and find and set the appropriate settings

http://dlcdnet.asus.com/pub/ASUS/mb/slot1/via693/p2v-b/p2vb-102.pdf

attach the CPU fan leads to the proper header on the Motherboard

Now check out the RAM slots, there are 2 latches at either end of each slot. Don't put the ram in yet move the latches into an upright position. The should be firm in place you should NOT be able to wiggle them. If there is some PLAY in them we might have just found your ram problem. These latches sometimes jar a little bit up and thus PREVENT the ram modules from seating properly. Any latches that had some PLAY in them just give them a bit of downward pressure (Don't have to FORCE them) until you here and/or feel it click back into place. Now fold down the latches and insert the SDRAM cards once in place fold the latches up until they LOCK into place and hold the ram steady. If any SLOTs are empty fold their latches up too (There are little sensors under these latch arms, that if ANY are down it prevents the Rams address bus from energizing to protect any improperly seated modules)

Now insert your Video card, If there is a latch at the back of the AGP slot make sure that engages properly (Don't worry if there is not one SOME of the older ones didn't have them) just make sure the card seats down all the way into its slot.

Now install any other cards I had you previously remove from the system install any wires from the front panel header that might have been removed or jarred loose, make sure that your case fans are attached to their headers.

I think your ready to give it a try NOW.
When you boot up it may pause asking you to confirm a memory checksum error as the Memory level should be different from the LAST time it boot press what button is says to do so to continue. After the ASUS logo blinks off screen press <Delete> to enter BIOS make sure the Video card setting is for AGP and not PCI press <F10> to save and exit.

This SHOULD have you up and running if not comment back and I'll try to assist you further.

For your information the last Generation of Winows supported with drivers for this board are Me/NT/ and 2000

When you are next ready to upgrade I would recommend getting a more modern motherboard with integrated graphics (If cost is an issue at the time) It will improve your upgrade and support options

Hopefully this helps you
Dave
