CPU/Mobo Is something wrong with the RAM stick ?

[sagar.sdm]

I have a 5 months old PC with following config -

AMD Athlon II X4 630 and ASUS M4A785TD-V EVO combo

Corsair XMS3-1333MHz Platinum Series - 2*2GB (both came together as a bundle)

OS - Windows 7 64 Bit

So, this morning I happened to give CPU-Z a try and this is what I saw (with both the RAM sticks installed) -

I was shocked to see that the the RAM stick in slot#4 showed weird values (highlighted in red) like max. bandwidth = PC3-100 (8MHz) as against the max. bandwidth = PC3-10700H (667MHz) where I was expecting to see the same values for both as they are supposed to be identical. I do not know the reason behind this. Can something be wrong with the RAM stick in slot#4 ??

As basic troubleshooting step I checked CPU-Z values for both the sticks in the same slot but with only one installed at a time and this is what I saw -

with just the 1st stick installed -

with just the 2nd stick installed -

And I could still see the difference among the two that I've highlighted in red. Can you guys please help me comprehend these values? Is there anything wrong with one of the RAM sticks ? Should I get it replaced ?

Thanks in advance,

Sagar

Did you try installling the "faulty looking" ram module in different memory slots? Does it still come up with these discrepancies?

Have you also tried a CMOS reset? How does the machine perform with just that one faulty looking memory module installed?

It could be possible that CPU-Z is 'reading' the values incorrect of the chips. Check what the SPD information is showing in the BIOS.

+1 to teh above.Its the best way to find out the specs of your RAM.BTW if RAM frequencies are different for 2 different sticks then it defaults to the lower frequency.How come they are running at different speeds

Try the MemOK! feature of your ASUS board as well, I thought MemOK! sorted such issues out on the first boot itself but try using it yourself through the BIOS

I think that the Corsair XMS 3 was a RAM kit paired together at the factory itself, can be a faulty RAM stick too, I have friends who are facing similar issues but that is with an Intel platform ( i5 760 + Gigabyte P55 UD2 ) ~ THAT IS WHY am suggesting the MemOK! feature present on all ASUS boards
