ASUS P5E64 WS Evolution - Tips, Tricks, Mods, BIOS, OCing & More...

[richard_crl032]

Hi Holmer/Rob,[PHP]

Thanks again for the continued advice and help ........

Glad also to report back that my system is now stable with IBT, Orthos and OCCT !!! The usual windows freeze after notification of dreamscape failing to load at OC and often at default settings is gone gone gone .........

Had to add 2nd fan to my Xigamatek 964 (using this due to height constraint of about 110mm in my Silverstone LC017 HTPC casing) and CPU temp at idle and load dropped by about 10C and 5C to around 40C and 65C respectively but not sure if this is indeed the main issue since with one fan, idle temp is about 48C and load around 70C which I thought is still OK. 2nd fan certainly improved the airflow to rear exhaust fans and also pasted a 70mm fan on top of the NB with 3M heat sensitive tape @1700 rpm ..... Note that this is at non-airconditioned room temp of about 28-30C ... yes, this is in tropical Singapore. Remembered that what got me stable was especially after setting CPU GTL at 0.63X as mentioned in the GTL link from Rob on having Wolfdale preferable at lower CPU GTL of 0.63X but LCC at Performance still does not work.

System:
Mobo : p5e64 ws evolution
CPU : e8600
Hsf : Xigamatek 964 with 2X Scythe 92mm Blue LED @2400RPM push-pull fans with speed control
RAM : 2x2G DDR3-1600 Cosair c9 DHX
GPUs : 4870X2 Crossfire
PSU : Aerocool 1020W
Display : Dell 3007
Casing : Silverstone LC017
Harddisk: 2X Samsung Spinpoint 750G
Drives : LG Blueray/HDVD ROM and DVD RW
Fans : 2 intake 92mm Scythe @2800rpm LED, 2 exhaust 80mm orange Thermaltake 3800 rpm fans (great quiet fans) as well as Aerocool PSU 140mm fan and 80mm fan on 2X4870X2


Anyway, stable setting for my modest OC at 4GHz is as follows for reference to e8600:

BIOS build: 602
Ai Overclock Tuner: Manual
CPU Ratio setting: 10
FSB strap to North Bridge: 333
FSB Frequency: 400
PCIE Frequency: 100
DRAM Frequency: 1601
DRAM Command rate: 1N

DRAM Timing Control: Manual
1st Information:
CAS Latency 7
RAS to CAS Delay 7
RAS to PRE Time 7
RAS ACT Time 20
RAS to RAS Delay Auto
REF Cycle Time Auto
Write Recovery Time Auto
READ to PRE Time Auto
2nd Information:
Read to Write Delay (S/D) Auto
Write to Read Delay (S) Auto
Write to Read Delay (D) Auto
Read to Read Delay (S) Auto
Read to Read Delay (D) Auto
Write to Write Delay (S) Auto
Write to Write Delay (D) Auto
3rd Information:
Write to PRE Delay Auto
Read to PRE Delay Auto
PRE to PRE Delay Auto
All PRE to ACT Delay Auto
All PRE to REF Delay Auto
DRAM Static Read Control Disable
DRAM Static Write Control Disable

DRAM Skew Control: Auto
Ai Clock Twister: Auto
Ai Transaction Booster: Auto

CPU Voltage: 1.3475 (CPUZ at 1.280 load to 1.312v idle ... fluctuation of this mobo up to 5 steps??? at normal LLC or my Aerocool 1020WPSU issue??)
CPU GTL Voltage Reference 0.63x
CPU PLL Voltage 1.56
FSB Termination Voltage 1.30
DRAM Voltage 1.76
NB Voltage 1.41
NB GTL Voltage Reference 0.67
SB Voltage 1.20
Clock Over-Charging Voltage Auto

Load-Line Calibration Normal
CPU Spread Spectrum Disable
PCIE Spread Spectrum Disable
CPU Clock Skew Delay Auto
NB Clock Skew Delay Auto

CIE, TM, Speedtrap etc. all disabled

I will try to reduce some the settings e.g. Vcore of 1.3475v, CPU PLL from 1.56, NB Voltage from 1.45 etc. and any further advice on what is not necessary in my listed settings would certainly be appreciated.

Regards,
