Hi, I've been a lurker for almost 2 years and only now (sorry) I'd like to participate more in this amazing forum.
So I've a nice and strange build, I'm still studying and working so I had not a big budget, but I managed to buy a nice "gaming" rig (All the parts were unsold for ages or comes from huge online sales, even a gift from a research center unused "old" stuff). Btw, I'm not here talking about my setup, I'm only here because I'm in the "Overclock what you got!... Even if all your cheap parts screams I'm Locked".
I have an Asus H97M-E motherboard, an Intel Xeon E3 1231 v3 and a G. Skill 16GB Kit (F3-14900CL10D-16GBXL).
H97 + Xeon = BLCK and Multiplier are never going to "move"
H97 + Ram = Ok maybe we can do something...
I managed to achieve this timings:
DRAM Voltage 1.65v
DRAM CTRL REF Voltage 0.5 (1.65 * 0.5 = 0.825v)
DRAM CTRL REF Voltage on CHA 0.5 (1.65 * 0.5 = 0.825v)
DRAM CTRL REF Voltage on CHB 0.5 (1.65 * 0.5 = 0.825v)
DRAM Frequency = 1600 Mhz (1866+ no bandwidth gain on H97M-E)
Primary Timings
CAS# Latency 7 (6 = No POST)
RAS# to CAS# Delay 9 (8 = Memtest86+ errors)
RAS# PRE Time 9 (8 = Memtest86+ errors)
RAS# ACT Time 21 (20 = No POST)
Command Rate 1
Secondary Timings
RAS to RAS Delay 4 (Auto, and it should be the minimum)
REF Cycle Time 140 (139 = Memtest86+ errors)
Refresh Interval 65535 (Max. Allowed and still 100% stable, Wat???)
WRITE Recovery Time 12 (9 = No POST; 10 = Memtest86+ errors; 11 = No POST)
READ to PRE Time 4 (Auto, and it should be the minimum)
FOUR ACT WIN Time 16 (15 = No POST)
WRITE to READ Delay 4 (Auto, and it should be the minimum)
CKE Minimum Pulse Width 4 (Auto, and it should be the minimum)
CAS# Write Latency 5 (7/8 Should be, CAS# - 3 minimum possible but no POST -> 5 Stable)
Third Timings
tRDRD 4 (Auto, and it should be the minimum)
tRDRD_dr 6 (Auto, 5 = No POST)
tRDRD_dd 6 (Auto, 5 = No POST)
tWRRD 13 (12 = Memtest86+ errors)
tWRRD_dr 4 (Auto, and it should be the minimum)
tWRRD_dd 4 (Auto suggested 5)
tWRWR 4 (Auto, and it should be the minimum)
tWRWR_dr 6 (Auto suggested 7)
tWRWR_dd 6 (Auto suggested 7)
Dec_WRD 0
tRDWR 9 (Auto, 8 = No POST or POST + Memtest86+ errors)
tRDWR_dr 9 (Auto, 8 = No POST or POST + Memtest86+ errors)
tRDWR_dd 9 (Auto, 8 = No POST or POST + Memtest86+ errors)
Misc.
MRC FastBoot "Disabled"
DRAM CLK Period 3 (2 = Memtest86+ errors)
Channel A DIMM Control "Disable DIMM1" (Only DIMM0 used)
Channel B DIMM Control "Disable DIMM1" (Only DIMM0 used)
Scramble Settings "Optimized (ASUS)"
MCH Full Check "Enabled"
What do you think?
Btw my real question is about 2 other settings that I dind't touch: "Skew Control" and "RTL IO-L Control", I'd really like to try also these 2 other settings. I found nearly no infos online. I manually played with some "Skew control" and it seems to impact performance a lot, but the whole "skew" sub-menu has 6 different options with [1-63] has range and I have no clue about what should I aim (Low values, high values or a specific combination). The other sub-menu, "RTL IO-L Control", is about latency, I get it, but every step in any direction (from the auto values) seems to hurt performance (or unable to POST). Can you please help me with these 2 obscure settings? Ty for your time and sorry for my English.
