I recently bought an Asus Eee PC 1005HA-B from Best Buy. I wanted to upgrade the RAM to 2GB, so I bought a Kingston HyperX 2GB PC4200 (533MHz, 3-3-3-8 timing) SODIMM from Newegg. It received a lot of great reviews, with other netbook owners commending how fast it was with the CAS latency of 3. However, when I installed the RAM, I got a BSOD before Windows XP could load, with an IRQL_NOT_LESS_OR_EQUAL error. I know it’s a problem with the memory because when I stick the stock RAM back in, it boots fine. I’ve checked the BIOS for options to increase the CAS latency but I can’t find any option to do so. Am I out of luck with this RAM?
Afraid so, Jarad. Asus’s Eee BIOS doesn’t let you change your RAM timings. And the Intel GSE945 chipset’s maximum supported RAM speed is PC4200 533MHz, with timings of 5-5-5-15 or 4-4-4-12. So, unfortunately, you’re out of luck. On the bright side, 2GB DDR2/553 SODIMMs are less than $30. Even if you can’t get your money back, you won’t be out a fortune. But Kingston tends to have very good support; see if the company will let you exchange the RAM for one with looser timings that your Eee won’t gag on. And at such low processor and bus speeds, we doubt you’d be able to tell the difference between 3-3-3-8 and 4-4-4-12 RAM, anyway.
