769118 2009-04-28 07:13:00 Hi guys. I have a Compaq Presario 5420AU desktop, XP Home with SP3. My issue is that I can not install more that 512MB ram. Anymore and it won't startup. Anyone what can be done, about this, short of a new board which is beyond my expertise and costing. Thanks, Ian. ianhnz (4263)
769119 2009-04-28 07:22:00 Are you sure it is just not your RAM stick you are installing? It could be faulty.

Try it with just that stick and without the old one and see how it goes

769120 2009-04-28 07:24:00 Also, your BIOS may not support any more than 512MB. pcuser42 (130)
769121 2009-04-28 07:36:00 Hi Blam. I was using a 128 & 256 MB ram chips, my system only has two slots. After them and installing and booting up with the new single 512 MB chip I also tried installing the 128 and it would start.
Re pcuserwinvista comments I think you are correct, but is there anyway of tricking the BIOS? Thanks guys.

769122 2009-04-28 07:36:00 Sorry should read, After removing them and installing and booting up with the new single 512 MB chip I also tried installing the 128 and it would start. ianhnz (4263)

769124 2009-04-28 07:38:00 Just looked up the PC's Specs (www.imsmemory.com.au) - several places all say the same thing 512MB is the maximum it will take. wainuitech (129)
769125 2009-04-28 07:38:00 You would have to flash the bios to the latest version

When you say "does not boot" at what stage does it get up to? Can it access the bios fine?

Sometimes RAM of different timings can cause inability to boot, try changing them around and see if that helps

EDIT:Oh poos....just read your post WT:p

769126 2009-04-28 07:40:00 Posted at the same time Blam - post above yours. Just looked on HP's site, due to its age - cant see any BIOS upgrades either -prob runs well on OS/2, NT4 or 95. wainuitech (129)
769127 2009-04-28 07:42:00 Hi, again, blam6. I agree that the standard bios will not take more than 512, but was wondering if there is a work around to this? You also said that I "would have to flash the bios to the latest version". I went to HP's site and download and installed their latest. Made no difference. ianhnz (4263)
