Arctican Posted August 1, 2009 Share Posted August 1, 2009 Hi Wired. I have a Compaq Presario 2570CA, taking DDR 266 PC2100 SO-DIMMs (as listed in your 'memory selector', with the largest being 512MB) to a max of 1GB total memory. (I believe all the Presario 2500 series laptops take the same RAM, which is why I posted in this thread.) 1. I thot that DDR 333 PC2700 SO-DIMMs were all backward compatible with DDR 266 PC2100 (and sometimes PC3200 modules backward compatible with PC2100). Am I mistaken? :confused: 2. If Corsair PC2700 SO-DIMMs are backward compatible, would they also be shown in the mem selector compatibility list for this laptop? Or does the mem selector only list the modules which exactly match the OEM spec? 3. Hopefully this isn't off-topic: Would it be possible to use 1x1GB SO-DIMM, or must I use 2x512MB? :roll: I could sure use some advice on this, if possible. Thanks!

Arctican Posted August 1, 2009 Author Share Posted August 1, 2009 Have you tried clearing the BIOS? This is necessary on some systems when replacing memory . Hi Ram Guy. I'm not familiar with "clearing the BIOS". How is this done (after booting into the BIOS, of course)? Link to comment Share on other sites More sharing options...
Wired Posted August 1, 2009 Share Posted August 1, 2009 Guaranteed-Compatible Memory for your Hewlett-Packard Presario 2570CA 1. Yes, however that doesn't mean the laptop will recognize it. Proprietary systems are rarely set to do so. 2. Only what they guarantee. Since they can't account for the proprietary nature of the laptop, the lowest common denominator is listed. 3. No. Link to comment Share on other sites More sharing options...
