PharaoTut Posted December 9, 2005 Share Posted December 9, 2005 Hello, I have recently purchased laptop HP Pavilion ZE2308 with Mobile AMD Sempron 2800+ processor (socket 754) with FSB 199.0 MHz. This laptop is based around ATI Radeon Mobility Xpress 200M chipset with southbridge ATI SB400. It came with one 256MB module PC2700 (166 MHz 2.5-3-3-7) from MOSEL. Therefore I have bought another 512 MB module PC2700 from Corsair VS512SDS333 (166 Mhz 2.5-3-3-7). From the time I have added it in, I started to have intermittent problems of not be able to start laptop at all, or it would give me STOP ERRROR blue screen before it would be able to load WinXP Home. I have tried to change position of these two memory modules or remove the original MOSEL memory module, and I still had this problem. When the computer boots up and load WinXP, all is fine but problem is that I can not make it boot in many occasions or with the STOP Error blue screen only. When I remove Corsair module and use the original 256 MB module only, I do not encount such 'strange' behaviors. I have installed latest drivers from HP website, updated the WinXP, as well as the BIOS (latest F.13 from November 2005). I said 'strange' because if I can boot up and use the MemTest86+ v 1.65, the standard test tested both memories with not prob. So at this point I am not sure if its just incompatibility between Corsair VS512SDS333 or is has a problem. The settings for Memory found through CPU-Z program are: FSB=199.0 Mhz Memory Frequency: 159.2 Mhz CAS Latency: 2.5 RAS# to CAS# Delay: 3 RAS# Precharge: 3 Cycle Time: 7 Bank Cycle Time: 10 Dram Idle Timer: 16 Both memory modules shows same SPD Timings Table. Note: I see that FSB and memory frequency are not same, but in BIOS there is not any option to change frequencies, memory settings, nor voltages so I assume if it works for 256 MB module alone it should be OK for both of them as well. Thank you for any advice or help. Best, AleX Link to comment Share on other sites More sharing options...
