F2-8500CL5D-4GBPK and EVGA 123-YW-E175-A1 LGA 775 NVIDIA nForce 750i SLI

I have been unable to use this memory above 800 even with default 6-6-6-18 timings with ANY voltage setting.. i am very disappointed in this product so far.

please provide me with ALL required settings to get this memory to work at 1066 and 5-5-5-15 as advertised

[G.SKILL]

please try to set it unlinked at DDR2 1066 and timing 5-5-5-15 2T
and also add the memory voltage to 2.1v, CPU VTT voltage 1.4v
thanks

i have already done that. did not work
i even loosened the timings a bit to 6-6-6-18 still not working

can you supply the rest of the settings for the advanced page so i can check them. they seem to be correct though.. they match the ones you have posted for the 780i

i see that this memory is not approved by evga - could it be a compatibility issue?

we've tested this combinatio but didn't find any problem
If there is still problem, please RMA with us
thanks

hello, i am having a similar problem with the same motherboard and same memory. it runs fine at 800mhz 5-5-5-15-2T

but when i try to set it at 1066 with automatic settings with 2.1v i get bsod's and memtest fails hundreds of errors.

Need to enter the timings manually, set command rate/timing to 2N, set speed manually and also check your tRFC, needs to be around 56.

Accidentally double posted lol

what should i have for settings for the ** Advanced Memory Settings ** ??

The settings in question:

tRRD [Auto(4)]  1-15
tRC  [Auto(32)] 1-31 <-- makes no sense that auto sets at 32 when the maximum manual setting is 31. Also is this the tRFC that you were talking about setting at 56?
tWR  [Auto(6)]  1-6
tWTR [Auto(10)] 1-15
tREF [Auto]     7.8uS or 3.9uS

i have no idea what these settings are actually for. i only know what the top have of the settings do. (The Timing settings)


thank you.

also

Need to enter the timings manually, set command rate/timing to 2N, set speed manually and also check your tRFC, needs to be around 56.

My only settings for "command rate/timing" is 1T or 2T or auto.
