Hi guys and gals,

I am in at the overclocking stage of my Tom's Hardware budget overclock (see link to PC build discussion) I opted for the following essentials:


  • [*]Intel Pentium® Dual-Core E2160 1.8GHz,
    [*]OCZ DDR2 PC6400 4GB KIT, Reaper X HPC, 2x2048MB, Heat Pipe, (CL4-4-3-15), E.P.P
    [*]OCZ Vendetta CPU Cooler Socket 754/939/940/AM2/775, 92mm Fan
    [*]MSI P35 NEO2-FR, P35, Socket-775, DDR2, ICH9R, SATAII, ATX, GbLAN, 2xPCI-Ex16


I have set the OCZ PC2-6400 ReaperX HPC Enhanced Bandwidth 4GB Dual Channel using the bios to the following:

tCL 4
tRCD 4
tRP 3
tRAS 10
tRFC 36
tWR 3
tWTR 3
tRRD 1
tRTP 3
Voltage 2.0

Now, i did get some good initial performance:

2741 PCMarks 1.8Ghz
3278 PCMarks 2.4Ghz
3784 PCMarks 3Ghz

But she started to hang. I think its the memory but cannot be sure. Any ideas on some 'stabler' settings?
