help with settings

[sydeccles]

Just installed 4 gig of memory - OCZ 4GB (2x2GB) PC2-6400C5 Dual Channel Vista Gold Series DDR2 (OCZ2G8004GK)

Need a little guidance with the memory settings


I have the CPU set at 3 gig


Motherboard - Abit IP35 (Socket 775) PCI-Express DDR2 Motherboard
CPU - Intel Core 2 Duo E2180 "LGA775 Conroe" 2.00GHz (800FSB)
Graphics - OcUK ATI Radeon X1950 Pro 256MB GDDR3 HDTV/DVI (PCI-Express)

Please any info on how to set the RAM timings?
Settings so far

External Clock: 300Mhz
Multiplier Factor: 10

PCIE: 100

Dram Command Rate: Auto
Dram Timing Control: Manual
Dram Speed: 1.1.00
5-5-5-5-18
Ras to Cas Delay: Auto
RefreshCycle Time: Auto
Write Recovery Time: Auto
Write to read Delay: Auto
Read to Precharge: Auto
Command Rate: Auto

DDR2 Voltage is set to 2.1v
System crashes if set to 1.125, with 5-5-5-5-18 set manually
System set to 1.125 & DRAM Timing set automatically then according to CPU-Z the memory is
DRAM frequency 360 MHz
FSBRAM 5.6
CAS Latency (CL) 6 clocks
RAS to CAS Delay 6 clocks
RAS# Percentage 6 clocks
Cycle Time 18 clocks
Command Rate 2T

Is this OK or can I do better ?

Also CPU-Z shows the CPU
With a core speed of 1800 MHz
Multiplier X6……………not sure why as its set to X10 in the BIOS
Bus Speed 300 MHz
Rated FSB 1200
Also installed Zalman CNPS9500-LED CPU Cooler

Do I need to turn it (Speedstep) off or is it OK to leave it?

 

[sydeccles]

1800mhz and the x6 multiplier is due to the Speedstep power-saving mode coming on at idle.

Try setting the MCH voltage to 1.37v to see if you can do 5-5-5-5-18 .

Still have a problem with the system crashing, secondly, is setting the MCH voltage to 1.37v non damaging ?

Need some help

What am I doing wrong, setup keeps on crashing, I am trying to get to 3 GHz


CPU to 3 GHz
Set Dram Speed 1.1.00
DDR2 Voltage to 2.1v
MCH voltage 1.37v


System is:
Abit IP35 (Socket 775) PCI-Express DDR2 Motherboard
Intel Core 2 Duo E2180
Zalman CNPS9500-LED CPU Cooler
OCZ 4GB (2x2GB) PC2-6400C5 Dual Channel Vista Gold Series DDR2 (OCZ2G8004GK)
Seagate Barracuda 7200.10 250GB
OcUK ATI Radeon X1950 Pro 256MB GDDR3 HDTV/DVI (PCI-Express)
Alaska Ultra Quiet 460W

 

[sydeccles]

ABIT IP35 + E2180 O/C Settings

Looks like progress is finally being made

CPU @ 3 GHz
CPU Core Voltage 1.24
Dram Speed 1.1.25 – (DDR2 750)
DDR2 Voltage to 2.1v
MCH voltage 1.37v

DRAM TIMING AUTO

CPU-Z gives me the following data

DRAM frequency 375 MHz
FSB: DRAM 4.5
CAS Latency (CL) 6 clocks
RAS to CAS Delay 6 clocks
RAS# Percentage 6 clocks
Cycle Time 18 clocks
Command Rate 2T

Memory spec according to Overclockers is:

http://www.overclockers.co.uk/showproduct.php?prodid=MY-086-OC&groupid=701&catid=8&subcat=813

- 800MHz DDR2
- CL 5-5-5-18
- 2.1 Volts
- 240 Pin DIMM
- 2.2V EVP**

What is the is better, trying to set the timings manually to 5-5-5-18 or trying to up the memory Dram Speed ?
