Which RAM "upgrade" can I use for an old HP dv6000 series laptop with AMD mobo
I'm upgrading the memory in an old laptop for a friend but I won't have the laptop in my possession until after I have purchased the memory. It is a HP dv6646us and I believe it has a 1600 fsb if I am not mistaken and if that makes a difference. Per the HP web site the mobo is a "HP Pavilion DV6000 series AMD motherboard 449903-001". The stock/recommended memory is 200-Pin SO-DIMM DDR2 667 (PC2 5300) at 1.8v with a timing of 5-5-5-15.
I'm pretty certain the bios can't be tweaked so I'm trying to get whatever the best performing memory is that the bios will recognize and that the system will actually utilize. The two possible "upgrades" I've found that I think might have a chance of working are ddr2 667 at 1.8v with 4-4-4-12 timing, or ddr2 800 at 1.8v and 5-5-5-15 timing, both reasonably priced and from quality manufacturers. I know both will work, I just need to know if they will work at their rated speeds/timing.
Can anyone that is familiar with that system/mobo/bios tell me for sure if one or both of these will work for sure in that particular laptop at their rated speed/timing? I've searched and searched and can't find a definite answer...
Which of the two RAM "upgrades" would give the best performance in that system assuming that they both could in fact run at their rated speed/timing, the 667 at 4-4-4-12, or the 800 at 5-5-5-15?
