Hey guys, wondering if you can help me out with this one. I just built a new PC.
i2500k
Z68 ASRock Extreme4 Gen3 Mobo
2x 4GB Corsair Vengence 1600 DDR3 RAM
Radeon HD6950 2GB
OCZ SSD 64gb
Hitachi 1TB HD
Windows Home Premium x64
Everything works great except for some strange reason, Windows will not boot whenever I try to place RAM in dual channel mode (slots 1/3 or 2/4). It boots into the BIOS fine and shows the proper mode, but when I go to Windows the computer just restarts itself over and over.
The things I've tried so far to no avail:
- placing RAM in both dual channel config slots
- updating BIOS to newest version
- upping voltage on RAM thinking perhaps dual channel may require a little more, no dice
- swapped memory with other DDR3 sticks to make sure it wasn't the sticks themselves, windows won't boot my backup sticks either when I try dual channel
- made sure all drivers were installed properly and windows is up to date
Single-channel on the other hand works just fine and seems to be pretty fast. But it's kind of eating at me that I threw down 1.3k on a system and I can't run dual-channel? I really don't think its a BIOS issue cause like I said, I can boot in fine.
A strange note though, when I tried to install Windows, it wouldn't allow me to unless I took one stick out. After install, I put the other one in single channel and it worked fine. I'm wondering if that was a precursor to this..
Anyone got any ideas? Thanks in advance!

Im guessing somewhere on the board something isn't connecting and its not allowing for your pc to register dual channel slots. If you want to you can goto your local PC store and get a new mobo and just send the old one back for a refund.

Ya but wouldn't you think that if that were the case, the BIOS wouldn't boot properly? Before I take my computer apart and rebuild shit, I wanna make sure there isn't a setting either in the BIOS or Windows issue that is causing this from happening. =p

Have you tried booting with a single stick in slot B1 or B2?

Windows has nothing to do with it. If your pc isnt booting into windows with the dual channel setup then its a motherboard error thats denying to PC from booting because of a specific error. If your case has a speaker and its able to hook into your mobo then your probably not getting to hear a beepcode.
I don't think theres anything you can do. Unless you want to run your pc in single channel.

Yes, it boots fine.

=[ I was worried you might say that lol. Ya I donno, its plenty fast at single channel but I'm wondering: if down the line I add more memory and fill up the other two slots, will I have the same problem?

Ok, that's really weird. Tried dropping the RAM speed to 1333MHz?

I found that the BIOS actually had it rated at 1333mhz initially. I manually set it to 1600mhz and nothing changed.

I had a similar problem with dual channel, I used information that came with the memory to set the timings voltage and speed, can be found on vendor website.

I suppose it's possible that a BIOS would use fallback memory settings when a single stick in installed and the (dysfunctional) SPD settings when it detected a dual-channel config. You could try loading the XMP profiles, but otherwise start at 1333 9-9-9-24 and work your way up.
|
There were two XMP profiles in my BIOS 1.3 and 1.2, tried both no dice.. it had the timings right at 9-9-9-24 from the start. =[
|
are they auto settings?
If they are try setting the timings,voltages manually and check the command rate.

Remove your CPU cooler, reseat your CPU, and put the cooler back on, being gentle. Recent Intel CPU's can lose a memory channel due to an unseated CPU from bumping the CPU cooler. Worth trying before you return anything.
