EP35-DS3L Questions

[esco459]

Hi there,

I'm having trouble finding a stable overclock. I'm running a q6600 and would like to hit 3.2ghz.

My system specs:

q6600 g0 vid 1.325
tuniq-120
4gb crucial ballistix tracer pc6400 - ram is rated to do 44412 @ 400 or 55515 @ 500, but I doubt it can do 1066 within temperature requirements.
8800 gt
antec 700w psu

Temps are not a problem, I never go above 59c.

Currently I am running stock settings, but I would like to achieve something amongst these lines: (these are the settings I have tried and had fail in p95)

Robust Graphics Booster Auto
CPU Clock Ratio x8 (or 9)
CPU Host Clock Control Disabled [Enabled]
CPU Host Frequency (MHz) 400 (or 356)
PCI Express Frequency (Mhz) 100
C.I.A. 2 disabled
System Memory Multiplier (SPD) 2x
DRAM Timing Selectable Manual

Performance Enhance = [Standard]

CAS Latency Time______5 [Auto]__________ ? 5 (or 4)
Dram RAS# to CAS# Delay____5[Auto]_____ ? 5 (or 4)
Dram RAS# Precharge Delay___5 [Auto]____? 5 (or 4)
Precharge Delay (tRAS)____15 [Auto]______ ? 15 (12)
ACT to ACT Delay (tRRD)___3 [Auto]______ ? auto
Rank Write to READ Delay___3 [Auto]_____ ? auto
Write to Precharge Delay_____6 [Auto]____ ? auto
Refresh to ACT Delay______40 [Auto]________ ? auto
Read to Precharge Delay_____3 [Auto]_____ ? auto
Static tRead Value______4 [Auto]_________ 1-31 (tried 7-12 all fail p95)
Static tRead Phase Adjust___0 [Auto]_____ 1-31 auto

System Voltage Control__Manual__
DDR2 OverVoltage Control__ Normal +0.3
PCI-E OverVoltage Control_ Normal
FSB OverVoltage Control___ Normal +0.1
(G)MCH OverVoltage Control Normal +0.2
CPU Voltage Control_______ Normal 1.435 (1.39 windows)

Limit CPUID Max. to 3.....................: [Disabled]
No-Execute Memory Protect............: [Enabled]
CPU Enhanced Halt (C1E)................: [Disabled]
C2/C2E State Support....................: [N/A]
x C4/C4E State Support..................: [N/A]
CPU Thermal Monitor 2(TM2) ...........: [Enabled]
CPU EIST Function.........................: [Disabled]
Virtualization Technology................: [Disabled]

Can you guys see anything I may have missed in the settings? I'm really stumped here, the p35-ds3r I used to have was much easier to tweak. I suspect it has to do with the settings that I have left at auto. Unfortunately I'm not sure where to find information to set them based on the ram equipped. Would appreciate your help thanks.

Re: EP35-DS3L Questions

Forgot to add that I am using the newest bios, f6a - and also my ram configuration is 4x1.

Re: EP35-DS3L Questions

Just so you know, Crucial is a Biggie on my Ga-P35 not compatible list. They do also Die very often. To save yourself some time and headaches, please at least test each stick in slot one, one at a time. At stock timings, speed, and voltages to be sure you do not have a Dead or dying stick in the mix

For 4x1 at 3.2 I would suggest these settings >>>

Robust Graphics Booster Auto
CPU Clock Ratio x8
CPU Host Clock Control Disabled [Enabled]
CPU Host Frequency 402
PCI Express Frequency (Mhz) 100
C.I.A. 2 disabled
System Memory Multiplier (SPD) 2x
DRAM Timing Selectable Manual

Performance Enhance = [Standard]

CAS Latency Time______4
Dram RAS# to CAS# Delay____4
Dram RAS# Precharge Delay___4
Precharge Delay (tRAS)____12


ACT to ACT Delay (tRRD)___3-4
Rank Write to READ Delay___3-6 (May need a bit more)
Write to Precharge Delay_____4-6-8
Refresh to ACT Delay______52-62
Read to Precharge Delay_____3-6
Static tRead Value______7-10
Static tRead Phase Adjust___Auto Always

System Voltage Control__Manual__
DDR2 OverVoltage Control__ Normal +0.3
PCI-E OverVoltage Control_ Normal
FSB OverVoltage Control___ Normal +0.1
(G)MCH OverVoltage Control Normal +0.2 << may need 2.5 but not likely
CPU Voltage Control_______ Normal 1.435 (1.39 windows) <<< May or may not need more, only your CPU can let you know

Limit CPUID Max. to 3.....................: [Disabled]
No-Execute Memory Protect............: [Enabled]
CPU Enhanced Halt (C1E)................: [Disabled]
C2/C2E State Support....................: [N/A]
x C4/C4E State Support..................: [N/A]
CPU Thermal Monitor 2(TM2) ...........: [Enabled]
CPU EIST Function.........................: [Disabled]
Virtualization Technology................: [Disabled]

And you should go back to a NON beta BIOS for sure >>>

4X1 is not a good combination for overclocking. You would be better off either finding the two fastest sticks (2X1) or selling them and going 2x2GB

Yeah, I have heard/read that from many different sources.

Tried to run at 4-4-4-52-4-7 last night, it went for 4h 5m before p95 failed. Will keep trying. ;P

Re: EP35-DS3L Questions

Please post where you are so I can see what may be the cause. And yes the above is true. When you do post back please post the full table of settings that fail for you

And since you are playing with memory, you need to be testing with memtest86+ not P95. You use that ONLY after you are sure the ram is stable, otherwise you will not know if it is your CPU or ram causing failures

Re: EP35-DS3L Questions

I would run 5-5-5 on the memory, not 4-4-4. The increase in CPU speed will improve performance over memory timings

Re: EP35-DS3L Questions

I went back to the F5 bios.

Robust Graphics Booster Auto

Passed memtest, and 12+ hrs of small FFT in p95

Further testing needed, I'll report again when I conduct said tests.
