Hey RAMGuy i'm in the middle of something i think. I had problems with stability and so i tweaked the M.I.T.


Here are some facts:



This comes from the CPUZ dump:


Chipset & Memory:


Northbridge Intel P35/G33/G31 rev. A2

Southbridge Intel 82801IR (ICH9R) rev. 02

Graphic Interface PCI-Express

PCI-E Link Width x16

PCI-E Max Link Width x16

Memory Type DDR2

Memory Size 2048 MBytes

Memory Frequency 533.3 MHz (1:2)

CAS# Latency (tCL) 5.0 clocks

RAS# to CAS# (tRCD) 5 clocks

RAS# Precharge (tRP) 5 clocks

Cycle Time (tRAS) 18 clocks

Command Rate (CR) 2T


Memory SPD




Timings table

Frequency (MHz) 270 400

CAS# 4.0 5.0

RAS# to CAS# delay 4 5

RAS# Precharge 4 5

TRAS 13 18

TRC 15 22


EPP profile 1 (full)

Voltage level 2.100 Volts

Address Command Rate 2T

Cycle time 1.875 ns (533.3 MHz)

tCL 5.0 clocks

tRCD 5 clocks (9.25 ns)

tRP 5 clocks (9.25 ns)

tRAS 15 clocks (28.00 ns)

tRC 22 clocks (41.00 ns)

tWR 8 clocks (15.00 ns)


and same as other ram.


tRAS is 18 or 15 ? If i set manually at 15 at bios it remains at 18. Also in bios its says ~2.26v go for ram slots.


Is this 18/15 the source of my problems (BSOD after some stressing or 24/7 on) ?
