Dear forumers, I would like to ask a question about combining these 2 sets of RAM. The Kingston 1333mhz CL7 runs at 1.65v, and the Crucial 1333mhz CL7 at 1.50v. By default, the BIOS on my Asrock P67 Pro3 (with an Intel Core i5-2500 @ 3.3Ghz) runs them both at CL9, at 1.59V. Memtest86+ 5.00 is okay with that, no errors. Of course, I'd like to utilize the CL7. Would someone know which settings to apply in the bios, and if it's possible with these two different sets? These are the options I can change in the DRAM configuration, currently (automatically) at: CAS# Latency: 9 RAS# to CAS# Delay: 9 Row Precharge Time: 9 RAS# Active Time: 24 Command Rate: 2N Write Recovery Time: 10 Refresh Cycle Time: 107 RAS to CAS delay: 4 Write to Read Delay: 5 Read to Precharge: 5 Four Activate Window: 20 CAS Write Latency: 7 ODT WR (CHA) Auto ODT WR (CHB) Auto ODT NOM (CHA) Auto ODT NOM (CHB) Auto MRC Fast Boot Enabled Thanks in advance!
