Memory Dual channel problems

Recommended Posts

I'm having problems getting my memory to run in dual channel and stable.

 

I put the modules in slots 2 and 4 and it will work OK for a while then the PC will freeze and I need to reboot. I tried running prime95 and it ran for about 2 minutes before getting errors.

 

If I put the modules in slots 1 and 2 then they run in single channel and at only 166Mhz and 2T but they will run prime for 13+hours with no problems. ?

 

I've also got a problem with slot #3. If I put any module in this slot then the PC won't even post. The diagnostic LED's at the bottom of board stop at 3 lit and nothing else happens.

 

I've put the memory in my wife's PC and run memtest and prime with no problems with memory at full speed and I've put my CPU in hers with my memory and again it worked fine.

 

I RMA'd the board to where I bought it and got it back a week later with a note telling me there was nothing wrong and they had charged me £20. :(

 

Any advice would be greatly appreciated. :)

Hello,

 

Make sure that all 4 power connectors are plugged into the board

# 24pin ATX connector.

# 4pin +12v P4 connector, near the ATX connector.

# Floppy power connector, under the CPU socket.

# Hard drive power connector, on top the chipset fan.

Plug your GFX card in the PCIe slot

# Make sure it is inserted correctly into the slot.

# Connect any power cables to it if one is required.

 

Clear your CMOS for 10 minutes

# Remove the power cord from the back of the power supply.

# Move the CMOS jumper to the clear position and leave it there for 10mins.

# Make sure you move it back to the save position after.

Insert the memory into the Orange slots

A quick question before trying this but why do I need the HD and floppy power connectors plugged into the board? I run them off my PSU at the moment. Will this make a difference?

You need to wire both the motherboard power connections. Thes do not power your floppy/Hard drives, these need additional power connections from your PSU ;)

 

The first part powers the motherboard only. then you need additional power conncetions for your other components.

OK memtest found 49 errors!! :eek:

 

I'm just letting it do pass 2 then I'll try with my other 2 modules of Ballistix.

 

It's strange that the memory passes memtest ok in my wifes rig. :(

 

Will post up what happens with my other memory.

You have the setting for you memory off just because it runs fine in another rig doesn't say how it run in this one. I have the same memory runs great up to 270mhz.

slight possibility it may be the PS, the Seasonic PS's seem to pop up as a possible culprit, and, if you didn't have the other two power leads hooked to the MB it could lead to problems. did you try setting the bios to the specs Sharp gave you????

 

do a search for crucial memory bios settings, you may just be a couple of changes away from getting it to work.

OK using Sharps setings I got lots of errors.

 

Using Lowboys settings I got 16 errors over 2 passes. So quite an improvement.

 

I did try Sharps settings with memory set at 170Mhz and the first pass was clear the 2 nd pass only had 2 errors.
