Solved Getting a 1:1 Ratio for E7400 and DDR2-800 6400 RM Tags: Memory DRAM Frequency DDR2 Configuration Overclocking Last response: June 16, 2012 12:25 PM in Overclocking Share DW_2012 January 8, 2012 11:14:02 PM Hi, all, Running a E7400 2.8 GHZ @ 3.5, due to a 10.5 multiplier by 333. Thing is, the DRAM Frequency is set to 800Mhz, with timings of 5-5-5-18, which is fine, but it gives a ratio of 5:6. I've read that when O/C 1:1 is ideal, but not sure how this would be possible with this configuration. I've also been told that everything is fine as-is, provided Memtest passes successfully. Any advice would be helpful. So far, the O/C @ 3.5 is very stable at 1.35 voltage.

Share deadjon a b K Overclocking February 13, 2012 9:19:32 AM The 100Mhz he is losing will not be worth it. 1:1 ratio is for stability. Run Prime95 Blend test for 8 Hours (Or overnight) and check for errors. This will tell you if you are stable or not. If you are stable, 5:6 will be fine. If not, 1:1 maybe fine but it does differ from Chip to Chip and Mobo to Mobo. m 0 l Can't find your answer ? Ask !
