I've bought 2x2gb of this:
Scan Computers UK: 2GB Dane-Elec Celenade Major, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 6, Retail
yea, i know it's rubbish but there... anyway, it's PC-6400 and rated cas6.
system runs absolutely fine, boots to windows, install programs etc. haven't tried games yet though.
all 4gb is there + recognised by the bios + cpu-z
problem is that occt + orthos either crash or find an error within the first couple of minutes of being run on memory intensive tests - cpu only is fine.
current bios settings are as below,
Robust Graphics Booster___________ [Auto]
CPU Clock Ratio ____________ [9]
Fine CPU Clock Ratio ____________ [0.5]
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [400]
PCI Express Frequency (Mhz)_______ [100]
C.I.A. 2__________________________ [Disabled]
System Memory Multiplier (SPD)____ [2.00]
DRAM Timing Selectable_______ SPD __ [Manual]
Performance Enhance = [Standard]
CAS Latency Time________________ 5
Dram RAS# to CAS# Delay_________ 5
Dram RAS# Precharge Delay_______5
Precharge Delay (tRAS)__________ 18
ACT to ACT Delay (tRRD)_________ 3 [auto]
Rank Write to READ Delay________ 3 [auto]
Write to Precharge Delay_________ 6 [auto]
Refresh to ACT Delay______________ 62
Read to Precharge Delay__________ 3 [auto]
Static tRead Value_______________ 8 [auto]
Static tRead Phase Adjust________ 0 [auto]
System Voltage Control____ [Manual]
DDR2 OverVoltage Control__ [+0.1V]
PCI-E OverVoltage Control_ [+0.1V]
FSB OverVoltage Control___ [+0.1V]
(G)MCH OverVoltage Control [+0.2V]
CPU Voltage Control_______ [1.33750V]
Limit CPUID Max. to 3.....................: [Disabled]
No-Execute Memory Protect............: [Disabled]
CPU Enhanced Halt (C1E)................: [Disabled]
C2/C2E State Support....................: [Disabled]
x C4/C4E State Support..................: [Disabled]
CPU Thermal Monitor 2(TM2) ...........: [Enabled]
CPU EIST Function.........................: [Disabled]
Virtualization Technology................: [Disabled]
other than the standard settings i.e. 5-5-5-18 and 6-6-6-18 and changing 'refresh to act delay' between 52-62 thats all i've tried from stock apart from voltage changes as i'm not quite sure what the ranges should be.
am just going to see if its more stable at a slightly lower fsb, but i'd be grateful if someone could shed some light!
i'm guessing since this was such cheap ram, there's some setting i may need to relax?
cheers for the replies...
