DX58SO2 + F3-12800CL9T-12GBRL + i7-960

[Mitalis]

I have an Intel DX58SO2 motherboard with an Intel Core i7-960 with Gskill RipJaw 12GB Triple-Channel 1600DDR3 memory.

I have the RAM plugged in the blue DIMM sockets. BIOS sees each stick of ram, however it?s not at the correct clock speed. The RAM is clocked at 1066mhz.

I have attempted to override these settings adjusting the clock speed to 1600 and this results in the motherboard reverting the settings back to default.

I have performed a search on various forums including newegg product reviews and people have said they have had success with this type of ram by simply setting the XMP profile. I have also tried setting the 1600 profile using the Intel Extreme Tuning Utility with no success. Upon restart the utility tells me it reverted the settings back to default due to improper settings.

Is it safe to assume since BIOS keeps reverting the speed back to 1066 one of the memory modules might be faulty?

Ok quick update, I just tested each memory module individually and tried applying the 1600 XMP settings via the Intel Extreme Tuning Utility and every single time I rebooted from making a change it reported it had to revert the settings due to improper settings... I tested each one of the memory modules in the blue DIMM slot... For some reason if I plugged in any of the memory modules into the black slots, the computer would beep 3 times indefinitely indicating there is some memory problem.

I'm finding the odds of 3 of 3 sticks of RAM being bad... I would really appreciate if I can get some specifics here as to what exactly I should be doing in this process because I can't help but feel like I'm doing something wrong when I'm setting the RAM.

Here's the settings 1600 settings in BIOS: http://i.imgur.com/vHP05.jpg

Here are the proposed 1600 settings in BIOS: http://i.imgur.com/pRvfU.png

Any advice?

First, you'll want the latest BIOS for your mobo, if you don't already have it, next enable XMP in the BIOS and select the 1600 setting...and you should be good to go, it should set the sticks to 9-9-9-24, which is the settings for the set. Ensure the the DRAM sets to 1.5 and CR is to 2T

Thanks for responding.

I am running the latest BIOS for my DX58SO2 motherboard.. I'm running 0779 which Intel released on 4/6/2011.

If I go with the automatic settings, this is what BIOS shows: http://i.imgur.com/aPpxY.jpg
As you can see, the automatic settings are clocking the RAM at the wrong speed.

So here I'll attempt to set the settings manually in BIOS: http://i.imgur.com/bdLRE.jpg
These look correct right?

Manually clock/set the memory. Another user had this problem too.

Ok so these are the settings I put into BIOS (http://i.imgur.com/G8zOo.jpg)

Memory Voltage (V): 1.500
QPI / Uncore Voltage: (V) 1.2250
Uncore Multiplier: 24
Memory Multiplier Speed: 12:1600

tCL (Cas Latency): 9
tRCD (RAS to CAS Delay): 9
tRP (RAS Pre-charge): 9
tRASmin (Minimum RAS Active Time): 24
tRFC (RAS Refresh): 86
tRRD (RAS to RAS delay): 4
tWR (Write Recovery): 8
tWTR (Write to Read): 4
tRTP (Read to Pre-charge Delay): 4
tRC (Row Cycle Delay): 25
tFAW (Four Activate Window): 20
tCWL (CAS Write latency): 6
Command Rate: 2T

These are my CPU i7-960 clock settings (default settings)

Host Clock Frequency (MHz): 133
Multiplier: 26
Max Processor Speed: 3.47

When I apply these settings in BIOS, during POST, my computer beeps 3 times indicating something is wrong with the memory, if I reboot it defaults the RAM settings back to the underclocked settings.

Is there some application I can use to test whether one of the memory modules are unable to clock at 1600? I've applied these settings above (1 stick at a time) and every time during POST it beeps 3 times and reverts the settings.

If these settings look wrong to you, please let me know what exactly I need to change because I'm reaching a point where I'm about to return the RAM to NewEgg if I can't get it clocked as intended.

Thank you.

tRFC (RAS Refresh): 110
tRRD (RAS to RAS delay): 4
tWR (Write Recovery): 12
tWTR (Write to Read): 5
tRTP (Read to Pre-charge Delay): 5
tRC (Row Cycle Delay): 40

Try these timings, the original ones are much too tight, they look like for DDR3-1066. The BIOS is not configuring sub timings correctly for some reason.

Thank you

Ok so I have loaded in the settings based on your recommendations: http://i.imgur.com/N5wXs.jpg

Still getting POST errors indicating something wrong when it uses those settings.

Do my CPU (i7-960) settings look correct? http://i.imgur.com/70nt2

Or do I need to adjust them?

I just wanted to follow up on my status. It would seem the latest version of BIOS for the Intel DX58SO2 is incredibly finicky when it comes to adjusting the memory timings. I read that downgrading to the earliest version of BIOS 0603 will fix these issues. I can report that the memory modules are finally running at the intended speed: http://i.imgur.com/LEqwS.jpg

To the mods, I'd advise you guys to create a sticky for other users whom may have the DX58SO2 model and let them know that the newest BIOS will cause POST issues if you manually change the timings yourself.

Thanks for the info, will drop GSkill a note on your findings,
