You don't need any software to change those settings. It is not possible change with any software. You need to get in BIOS settings. You can do it when your PC is booting and you see the message on the bottom of the screen saying "press del to enter BIOS" or something. Usually it is del, but it can also be F1, F2, F12... depends on the mobo.

Once you are in, navigate around until you find the DRAM settings.

My BIOS DRAM settings screen looks like this:

Timing mode [AUTO]
Memclock Index value(MHz) [400MHz]
CAS# latency (Tcl) [2.5]
Min RAS# active time (Tras) [8T]
RAS# to CAS# delay (Trcd) [4T]
Row precharge Time (Trp) [4T]
Row cycle time (Trc) [11T]
Row refresh cyc time (Trfc) [14T]
Read-to-Write time (Trwt) [4T]
Write Recovery time (Twr) [3T]
1T/2T Memory Timing [2T]
S/W DRAM Over 4G Remapping [Disabled]
H/W DRAM Over 4G Remapping [Disabled]

You can see above those TRC TRAS TRP and TRFC I mentioned earlier. If you take in account the timing formula....

tras + trp = trc
trc + 4 = trfc

... you can see that they are set wrong.
Bare in mind that first line on the screen. All settings were set on "AUTO", so it is obvious that the BIOS is setting it wrong and producing the errors I got. Same errors you get. You need to set it on "MANUAL" and correct those timings.

My DRAM settings screen now looks like this:

Timing mode [MANUAL]
Memclock Index value(MHz) [400MHz]
CAS# latency (Tcl) [2.5]
Min RAS# active time (Tras) [8T]
RAS# to CAS# delay (Trcd) [4T]
Row precharge Time (Trp) [4T]
Row cycle time (Trc) [12T]
Row refresh cyc time (Trfc) [16T]
Read-to-Write time (Trwt) [4T]
Write Recovery time (Twr) [3T]
1T/2T Memory Timing [2T]
S/W DRAM Over 4G Remapping [Disabled]
H/W DRAM Over 4G Remapping [Disabled]

(I've highlighted the changes)

You should do the same.
Since I don't know your memory model and it's declared timings (ex. mine is 400Mhz, CLI2.5 8-4-4 <--those are first 5 lines below "timing mode" line), I can't tell you which setting should be where, but the principal is the same. Just set it on manual and implement the formula.

Regarding the voltage, it also set in BIOS, only different screen. Goes up to 3v. I suggest that you leave it be for now.


P.S. It took me over a year to troubleshoot that problem... Look here. Consider yourself lucky.

I say what I see. If you find my words offensive, then you find my reality offensive.
