[firas]

did you notice the 5-7-7-7-20 timings? this can't be normal right?

I am not 100% certain but I think that after you set the "Driving Strength Profile" to 1066 this will now show the timings in your bios. I noticed the same thing when I first started with this board and after I began enabling some things with my ram CPUZ began reporting the correct timings.

firas, try and set extreme memory performance to disable,it should help.my g.skills do the same if its on auto,but be careful when you change it to disable it will reset the cpu multiplier and fsb.i always start my OC by disabling this first then set up the OC.

Change it to manual and set your timings manually. My GSkill 8800s got picked up as 5-7-7-20, they are actually 5-5-5-15 so I've manually changed them and havent had an issue.

Under the profile, if I set disable I see 5-7-7-20, my next option is "profile2" is I set that then it shows up correctly as 5-5-5-15@1066.

sorry it was my mistake, at the beginning I set the “DRAM Timing Selectable” to manual, but that caused problems, tried to change various settings but nothing worked! so I left it at auto.

now I discovered that when it was at manual it was like this:

CAS Latency Time...............[ 5    ].........[ 5     ]
tRCD...........................[ 5    ].........[ 5     ]
tRP............................[ 5    ].........[ 5     ]
tRAS...........................[ 15   ].........[ 5     ]

corrected it and everything is running smoothly now

at this moment my “DRAM Performance Control” is:

Performance Enhance.............................[ Turbo ]
Extreme Memory Profile (XMP)....................[ Auto  ]
(G) MCH Frequency Latch.........................[ 333   ]
System Memory Multiplier........................[ 2.40B ]
Memory Frequency   ..............1066...... ......1020
DRAM Timing Selectable..........................[ Manual]

first it was like this

Performance Enhance.............................[ Turbo ]
Extreme Memory Profile (XMP)....................[ Auto  ]
(G) MCH Frequency Latch.........................[ 400   ]
System Memory Multiplier........................[ 2.0D  ]
Memory Frequency   ..............1066...... ......890
DRAM Timing Selectable..........................[ Manual]

then I tried to follow what PortCitySlim said and what i was in the link I mentioned to higher my ram frequency.

2.4 multiplier wasn’t available when latch is @ 400, but it was @ latch 333 (and came with the letter B not D)

i'm thinking of giving 2.5 a shot to bring the frequency a little bit higher than 1066 since my memory voltage now is set to 2.1 (which my shallow knowledge gives me a feeling that my current frequency doesn’t require it )



@PortCitySlim: you encouraged me to the 3600 idea and that’s what I did but at lower voltages than you mentioned, I even managed to pass prime95 at less vcore but left it at 1.25 (in bios) since it’s already too low

still concerned about the 2.1vram (here had similar settings @ 0.9) and same vcore with higher FSB
