I often get this warning message while working and the program inevitably terminates:
"The instruction at "0x10005f6c" referenced memory at "0x10005f6c" .The memory could not be "read" . Click ok to terminate the program."

i have no clue of what this could mean but its slowly irritating me since i always have to end the program , even if i ignore this and just click it away the program ends as well. I d be very thankful if u d let me know what this means and what can i do about it..
thanx

I had that message on the hourly basis. It is memory compatibility issue. I have GEIL and it is power-hungry RAM.
One or the combination of these things should help you:

- Manually set memory timings. There is a formula I posted once here that I got confirmed that it is valid by AMD ppl

tras + trp = trc
trc + 4 = trfc

Those acronyms should be adjustable in BIOS.
That is a must with GEIL RAM.

- Increase RAM voltage. Go to the max. If you have GEIL, or any other that has aluminum heatsink, there is no need to worry about overheating. You can only gain stability.

- If you OCed your PC, reduce the speed or increase the voltage. You are on the edge of usable.


There are other possible causes, but those above are 99% of the cases.

i actually made a report of the memory and cpu of my system,as u see i dont have an amd, i dont really understand much of what you replied. U d have to be a bit less technical . How should i increase ram voltage? and how should set the timings? do i need a program for it?
thanx

This is gonna take some time to type... be patient.

i am here

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 ve entered the bios setup but i cannot find the section related to the DRAM where is it exactly?

I don't know. If you post your mobo model, maybe I could download manual and tell you exactly what and where. While you're at it, RAM model will help too.

eh sorry but how do i find what my "mobo" is , i dont even know what a mobo is (a bit ignorant )

Motherboard.

Here's a tool that will hopefully tell you all I need to know. Says that it can save the report as text file... copy-paste it here.
