Hi forum! i have the pleasure of owning your product close to 2 years. love service and forum is great information thank you! Would like help to take my ram to the max! and if it breaks well it needed to be replaced with something faster anyway
my main concern are timings.
at present my settings are as follow


Robust Graphics Booster ... [AUTO]
CPU Clock Ratio ........... 10
CPU Frequency ............. 3.33GHz (333*10)
CPU Host Frequency (Mhz) .... 333
PCI Express Frequency (Mhz)..100
DRAM Performance Control
Performance Enhance..............[STANDARD]
Extreme Memory Profile (X.M.P.)..[Disabled]
(G)MCH Frequency Latch...........[Manual]
Memory to Bus Ratio ............ 1:1
Memory Frequency (Mhz) ..........333
DRAM Timing Selectable ..........[Manual]

Standard Timing Control
CAS Latency Time...4
tRCD ..............4
tRP'...............4
tRAS...............12

Advanced Timing Control
tRRD...............4
tWTR...............4
tWR................8
tRFC...............48
tRTP............... 4
Command Rate (CMD)....2


Motherboard Voltage Control
Voltage Type
>>> CPU
Load-Line Calibration [DISABLED]
CPU Vcore...............1.26v
CPU Termination…........1.200v
CPU PLL………….............1.500v
CPU Referen............:0.760v

>>>MCH/ICH
MCH Core.........1.220v
MCH Reference....0.760v
MCH/DRAM Ref.....0.900v
ICH I/O..........1.500v
ICH Core.........1.100v

>>> DRAM
DRAM Voltage ........2.1v
DRAM Termination.....0.900v
Channel A Reference..0.900v
Channel B Reference..0.900v

Thank you in advance for any suggestions!

Could try tweaking the the CR to 1T, may need a bit of NB or DRAM additional voltage

My P-35-DS3L can run 8gigs of this memory at the following settings:

DRAM Performance Control
Performance Enhance..............[Turbo] but I am not overclocking the processor

System Memory Multiplier ........[2.4] 333Mhz
Memory Frequency (Mhz) ..........800Mhz
DRAM Timing Selectable ..........[Manual]

Standard Timing Control
CAS Latency Time...4
tRCD ..............4
tRP'...............4
tRAS...............10

Advanced Timing Control
tRRD...............3
tWTR...............3
tWR................6
tRFC...............40
tRTP............... 3
Command Rate 2

Motherboard Voltage Control

CPU Vcore...............1.10v
MCH Core.........1.10v
DRAM Voltage ........1.86

You can see screen shots in my thread of HWmonitor, Memset and CPUZ showing these settings except for MCH. You will just have to take my word for that voltage.

Please notice settings in BIOS differ in Memset for:
tWTR set 3 Memset 10
tWR set 6 Memset 13 Write to precharge delayed
tRTP set 3 Memset 5

My board also has
Static t Read value set to 5
Static t Read Phase Adjust set to Auto, this may be tCR.

With 8gigs of memory Cas 4 is the only latency that will pass memory tests without errors.

Good Luck.

Edit:
Please note I am running set F2-8500CL5D-4GBPI-B, which may have different chips.

PS: any more tweaks i can try? i try tWR to 6 but its not stable

[Tradesman]

Glad to hear it, Enjoy!

[Numbtwerp]

updated settings just wanted you to take a look tradesman

[Tradesman]

Appreciate it! It's looking good, that doesn't mean you still can't play, keep a copy of your good, current, stable settings as fallback and can always experiment with the timings, might get something like MaxxMem to give you a graphical look at where you are, and then what the system does as you experiment. Have a feeling there won't be anymore drastic increases memory wise without raising FSB or DRAM Freq

[Numbtwerp]

new processor xD

[Tradesman]

If a link in there, doesn't appear to work

[Numbtwerp]

i EDIT my post #1 used to be E6400 thank you for all you dew! my SPD says (4-4-4-10 TRFC 16) at 266MHz is that correct? those timings seem pretty low?

[Tradesman]

Those are nice tight timings at 266, but thats in the SPD - which is just for info puposes, can find what you are running by using CPU-Z, run it and look int Memory Tab
