I have installed this motherboard along with my other hardware and now i need some help.

Can any1 please post a mini guide to successfully overclocking and stability checking with this mobo. Specs are as follows:

E6300
2gb(4x512) geil PC6400
Enermax 535W sli PSU
2x80gb raid 0 HDD
Arctic pro 7 cooler

Thanks in advance

Just search for the P5b, since they are the same - the E just has the updated rev chipset that should allow higher FSB.
 
Hi,

Try these settings for an E6600;

In the Advanced Menu go to;

CPU Configuration
Set CPU Internal Thermal Control to [AUTO]
Everything else except Execute Disable Bit should be set to [DISABLED]

Chipset
Leave all the memory timings on AUTO until you have got the CPU overclock sorted out

Spread Spectrum Control
Work your way through the menus and disable everything

SLI Broadcast Aperture
Leave this at Disabled

LDT Frequency
Leave this at 5x

Onboard Devices Configuration
Turn off the JMicron SATA controller - this will fix your cold boot issues

In USB Configuration
USB Legacy Support [DISABLED]

Then back up to JumperFree Configuration

AI Tuning
Set this to [Manual]

System Clocks - PCIe
Leave this at 100 for stability or upto 125 if you like your graphics as fast as possible

Voltage Control
Set the VCore voltage to 1.4
Set the VCore Offset Voltage to +100mV
Set the Memory Voltage to [2.259]
Set the NB Core Voltage to [1.563]

Reboot and re-enter the BIOS

Then go to the CPU and RAM FSB
Select unlinked
Adjust only the CPU at the moment
Start at 1200, then work upwards to 1500 in jumps of 48 FSB Reboot at each stage.


I got these off someone else, i used it for my 4300 and i have happily sitting at 3.2ghz. :p
 
well this is what i tried:


AI Tuning: Manual
CPU Frequency: 398 because of strap change and clockgening
DRAM Frequency: DDR2-796Mhz
OPCI Express Frequency: 100
PCI Clock Synchronization Mode: 33.33Mhz
Spread Spectrum: Disabled
Memory Voltage: 2.1
CPU Vcore Voltage: 1.375
FSB Termination Voltage: Auto
NB Vcore: AUTO
SB Vcore (SATA/PCIE): AUTO
ICH Chipset Voltage: AUTO

Memory Remap Feature: Disabled
Configure DRAM Timing by SPD: Disabled
DDRAM CAS# Latency: 4
DRAM RAS# to CAS# Delay: 4
DRAM RAS# Precharge: 4
DRAM RAS# Activate to Precharge: 4
DRAM Write Recovery Time: 2
DRAM TRFC: 35>>>considerable impact on performance and stability
DRAM TRRD: 3
Rank Write to Read Delay: 9
Read to Precharge Delay: 7
Write to Precharge Delay: 9
Static Read Control: Disabled

Modify Ratio Support: Enabled
Ratio CMOS Setting: 7
CIE Support: Disabled
Max CPUID Value Limit: Disabled
Vanderpool Technology: Disabled
CPU TM function: Disabled
Execute Disable Bit: ENABLED
PECI: Disabled


This gives me 2.8Ghz, i was able to boot into vista didnt run any stability tests but i have a hunch that it would be stable. the temps were core1:40C and core 2 41C.

I tried FSB 440 after that with x6 multi, it booted into vista for 5 seconds and i was happy since cpu-z showed 3.09GHz but then BSOD and auto restart of pc :(.

What should i do to take it past 3Ghz and be stable. i have seen people with 3.5Ghz stable with the same setup as mine. Unfortunately they dont state the values they used.

tried changing ram cycle clocks, slacker timings should work but they didnt. no post with 5-5-5-15-6-42.

im pretty sure im doing something wrong somewhere :confused:
 
temps spiking over 50 with fsb 398, returned to stock vcore, ram running at 2.1. going to run 3dmark06 to see stability and performance.
 
core 1 temp=56C
Core 2 temp= 53C

Are these normal?

im running arctic pro freezer 7 and also taking into account high temps inside the room.
 
ran 3dmark06 at 430x7. strangely the score came out to be 2360, lower than at 398FSB, the online results stated that im using some other drivers which are not official hence the low score? Dont know what that means.

Anyway moving on to 440x7
 
test failed after 6 minutes, harware malfunction, im gonna run more tests though. Have tried to to slacken the ram timings but 5-5-5-15-2-45 dont work.
re-installed the cooler and applied a bit more arctic silver. too early to say whether the temperature has been lowered or not but idle at 48C now and occasional rise to 53 when a programme is running.
