F3-16000CL9T-6GBRH settings with Gigabytre EX58-UD5

[Webbyboy]

Hi,

Just wondering anyone has the memory settings to run the memory at stock 2000mhz speed with the Gigabyte EX58-UD5 board? I intend to run 4ghz on my cpu too. Hopefully gskill support could help.

Thanks

help him=help me
I bought this and put it into my ex58-ud3r motherboard with core I7 920 D0 stepping. I tried to run this ram with settings according to gskills
http://www.gskill.us/forum/showthread.php?t=1322
It just won't run, won't boot, all fans on and just dead!!! My cpu can overclock to 3.8 with 1.2v without problem.
I tried running this ram with all the settings according to the gskills with 1440 instead of 2000mhz... and it won't boot as well. Is it broken?

Yeah723:
You should probably test each stick w/ memtest, it sound like you may have a bad stick or a bad slot

You'll want to start with stock settings 9-9-9-24, command rate 2T, DRAM voltage at 1.6, speed 2000, also what are your tRFC and tRC at?

One thing though. If I put the ram in auto and OC cpu to 3.6 with turbo. The ram would run at 900mhz>>1800mhz with timing 10-13-13-31 100 tRFC and command rate 1T. Do I still need to test?

[Tradesman]

Think if you change command rate to 2T you could tighten down the current 10-13-13-31 timings to 9-9-9-27 or 29 or so

now at 9-9-9-27 2T

what is FSBRAM, it is 2:10
MY tRFC is 100 though...
What should I put it as?

tRFC is basically used for stabilization, may try dropping it to 90 and then in increments of 5 till it busts, then take it up in 1 or 2 clicks at a time till stable.

You might get some ideas on the RAM and CAS from ehume's post at

we've been playing with his RAM and timings, have another poster headed over there also, so his thread may become a party site....LOL

Well his is P55 and it's dual channel, so it's much easier for him to get to 2000mhz and above. We are running 3 sticks and it's hard to get 2000mhz because of the 8:9 rule?

[yeah723]

Ican run at 1800mhz with 9-9-9-27 2T but with 100 tRFC. Let me try to make it 2000 or lower tRFC

Maybe you can try this
This is what I use and works fine.
4gb on your cpu may not really work, it needs a lot of work, but mine works for 3.6+ turbo=3.8.
My setting is below
In MIT (MB Intelligent Tweaker):

CPU Clock Ratio - 20x for 3.6GHz
QPI Link Speed - 36x
Base Clock Control - Enabled
BCLK Frequency - 180
Performance Enhance - Standard
Extreme Memory Profile - Disabled
System Memory Multiplier - 10

Uncore & QPI Features
Uncore Frequency - 4000 or 3600

DRAM Timing Selectable - Manual or quick

CAS Latency Time - 9
tRCD - 9
tRP - 9
tRAS - 27

Enter these for the other three as well.

Channel A Timing Settings

Advanced Timings
tRC - 27
tRRD - 4
tWTR - 4
tWR - 8
tRFC - 60
tRTP - 4
tFAW - 20
Command Rate - 2
Round Trip Latency - auto since I have no idea what this is

Advanced Voltage Control
Load-Line Calibration - Disabled
CPU Vcore - Normal
QPI/VTT Voltage - Auto
CPU PLL - Auto

PCIE - AUTO
QPI PLL - Auto
IOH Core -Auto
ICH I/O - Auto
ICH Core - Auto
DRAM Voltage - 1.640V
Rest to AUTO

Hope this helps. It works for me.
