need some tips OC

[coldsin]

I"m trying to OC E6400 to 2.8 and having some Vcore issue on this board.
need some tips on vcore please.

CPU: E6400
Memory: 4G G Skill 4-4-4-12
Motherboard: GA-P35C-DS3R

Did you read the sticky? >>
Gigabyte X38/P35/P965 (DS* DQ* S3) Overclocking and General BIOS tweaking Guide

If you did and still want some suggestions post your settings back and tell me where you want to clock to and I will give you some starter settings

Here is a TEMPLETE to post your settings with, add or remove anything your BIOS doesn't have or does have

Robust Graphics Booster___________ [Auto]
CPU Clock Ratio ____________ [8]
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [450]
PCI Express Frequency (Mhz)_______ [102]
C.I.A. 2__________________________ [Disabled]
System Memory Multiplier (SPD)____ [2.00]
DRAM Timing Selectable_______ SPD __ [Manual]

CAS Latency Time________________ ?
Dram RAS# to CAS# Delay_________ ?
Dram RAS# Precharge Delay_______?
Precharge Delay (tRAS)__________ ?
ACT to ACT Delay (tRRD)_________ ?
Rank Write to READ Delay________ ?
Write to Precharge Delay_________ ?
Refresh to ACT Delay______________ ?
Read to Precharge Delay__________ ?
Static tRead Value_______________ 1-31
Static tRead Phase Adjust________ 1-31

System Voltage Control____ [Manual]
DDR2 OverVoltage Control__ [+0.300V]
PCI-E OverVoltage Control_ [+0.1V]
FSB OverVoltage Control___ [+0.1V]
(G)MCH OverVoltage Control [+0.1V]
CPU Voltage Control_______ [1.25]

Here my bios setting.

i'm having issue on CPU Voltage, i try couple setting but whenever i boot to windows it gave me Blue screen, i was wonder whats the best voltage for E6400?

Thanks
Note: newbie ;)

Well first of all with 4gb you are going to need to make some changes in your timings with your ram.

What is your full settings? I will be gone here in a second, but please post your full settings and I will suggest better to you tonight when I get back.

The easiest way to find your voltage needed is to start with 1.45 CPU if you are not already that high and then work backwards until it isnt stable. For 3.6 you may need more then 1.45 and then you would for sure need better cooling, what are you using now for cooling?

My E6400 goes 2.8 G fine @ 1.35 volts.

[Lsdmeasap]

If you are having BSOD issues, go in control panel then system (Or right click your My computer and choose properties). Then the advanced tab as shown here >>>



Click Startup and Recovery and uncheck automatically restart as shown here >>>



This way you can cause the BSOD again and give me the code it tells you. To fast normally to see because it restarts. You will want to turn this back on later if you want. But giving me the code can help as well, because incase it isnt your memory settings or voltages the code will tell

I will be back later tonight if you are not around, please post your FULL MIT page settings so I can see what you need or have wrong

Thank you Lsdmeasap. I follow your BIOS tweaking Guide and it great. one little problem tho when i ran Orthos it fail ;(. should i increase Vcore?

[Lsdmeasap]

Well orthos fails because of ram or CPU, so you need to test your RAM with Memtest86+ for a while first to be sure that is not the issue >>>
Memtest86+ - Advanced Memory Diagnostic Tool

I let the main test ( The first test it runs run fully thru ) then hit C and choose test I then choose test #2 for about a half hour, then choose test again and choose #5 for about a hour.

That would be this order to choose a test # >>>
1. First press C

2. then 1

3. then 3

4. and finally select the test that you want to run

5. press Enter

6. and then 0 to get it running

14 hours pretty stable tyvm for the tips

[Lsdmeasap]

Thats pretty high Vcore, you sure you need that much? Hows temps with that?
