Hey,
I've just bought the kit in the title.
Everything runs fine except the speeds and i'm having a hard time finding the right timings.
Before i bought the kit i've asked the g.skill support if it's even possible to run it on my setup.
They told me that it is not possible to run 8gb modules on a i5 750 + p55 platform, but luckily they run.
On the first boot i've tried the XMP-profile 1, which sets the ram to 2000mhz, but without success, the system will not boot. At 1900mhz (bclk 190 + multi 20) the system boots fine, maybe the memory controller in the i5 is too weak for 16gb and the high speeds.
But i would be fine with 1900mhz and a bit tighter timings.
Now the timing problems:
If i set the XMP-profile 1, i'm getting timings of 9-10-10-29 and advanced timings of
tRC 39 tRRD 5 tWTR 8 tWR 15 tWTP 26 tWL 7 tRFC 4 tRTP 8 tFAW 23 CR 2
Without the XMP i'm getting these timings: 9-9-9-24 and advanced timings of
tRC 33 tRRD 4 tWTR 5 tWR 10 tWTP 21 tWL 7 tRFC 174 tRTP 5 tFAW 20 CR 1
the tRFC value with the XMP-profile can't be right in the bios i know, it shows 248 clocks on cpu-z.
I know my motherboard is not officially supported, but what do i have to use? XMP or better set the timings manual? (and should i let the advanced timings as auto or is there somewhere a official list for them?) Is there something like a timing-table for 1900mhz?
I've already ran prime95 multiple times. With 9-10-10-29 it ran over 4 hours, but with 8-10-9-26 it crashed after 3 hours already. I don't want to run prime that long for every little tweak i'm doing.
Motherboard -> Gigabyte P55 UD5
CPU -> i5 750 @ 3,8ghz
Bios F11c (latest)
VTT-voltage @ 1.180 (don't want to go higher since the max intel specs for the p55 is 1.21 i suppose?)
