Windows 7: Unganged memory ??

I have two identical Kingston 4 gig DDR3 PC 10700 (667 MHz) modules in this PC. My BIOS is set to unganged, which is its default setting. I don't think thats whats causing your long boot. Is it a long POST or a long boot to windows? Are your RAM modules matched? I'd compare the timings for each module at what ever frequency they are running at. If they are not close that could be your problem. Easy way to tell is to remove one module and see if you boot up faster.

But, it can be done with different sticks but is more likely to give problems.
Hello again,
So you are saying that the four columns with the 4 different specs and speeds all relate only to the slot 1 memory stick. I should check each slot and compare. The thing that threw me was it saying 266Mhz and 400Mhz. What is the speed that slot one's memory is running? I will check the rest. I don't understand all the data being presented {:-(!
Thanks again!!
Glenn
The 4 different columns show the timings that would be used if you ran that module at that speed/frequency. High end RAM run in an economy or low end motherboard could result in it being run at a lower frequency than its rated for. Mismatched RAM modules can cause it also. The SPD just tells the motherboard what timings to use at the lower frequency.
Thanks Sir,
I have been sidetracked into getting my added memory set up. But I will take time to read your explanations and hopefully absorb knowledge! Greatly appreciated!

Hey,
I have to go back into the box as I set the memory in the slots incorrectly. I will do that and see if that helps. Do you suggest ganged or unganged????? Will let you know when and if I get back online.......................

Going by what dwarf posted " for greater performance, as UnGanged (where each memory controller is responsible for a single channel ", I'd go with unganged.

Hello,
Well I sure wish I understood more, but I got lucky. I changed the chips to the proper order, rebooted and let it load optimized default, which was unganged BTW.
Not sure but the boot time might have quickened. But I did a system reassessement test and the processor went from pre-change 6.7 to post change 7.4. Memory went from 7.2 to 7.4, my onboard video score went from 3.6 to 4.1. All in all that seems like it did good. Still open for opinions and knowledgeable advice, but I am a happier camper!! Thanks to all that assisted! I checked the SPD and it showed 338.7 Mhz for ram speed, I guess that is what it is currently running.

In CPUz click on the memory tab. That will tell you what it is actually running.

334.9 doesn't sound right? Shouldn't it be something like 667 MHz?

I haven't a clue, I know the memory speeds say 400 MHz. So I am just guessing.....

What does the SPD tab report as to the memory capabilities? It sounds as though the effective memory frequency is 667MHz (remember that DDR memory transfers data on both leading and falling clock edges, resulting in an effective doubling of the actual clock rate), which would tie in quite nicely with the speed you report of 334.9MHz.
