SSD disappeared from bios -- RAM possibly at fault?

post #1 of 3
Thread Starter 
This is a long and complicated issue, but what I'm wanting to know is this:

Can RAM cause a SSD to not be recognized? More specifically, can overclocked RAM cause a SSD to not be recognized?

To give some more detail -- I recently bought some G.Skill Sniper Series RAM which runs at 1600MHz unless I apply XMP or manual overclock settings.

However, when I do either of these two things, it causes issues:

1. Sometimes, the computer will take the XMP settings. Sometimes it won't and it will get stuck I an endless reboot loop requiring a CMOS clear.

2. If the XMP works, windows loads fine. But if I restart, the computer turns off briefly during the restart process for about 8 seconds before turning back on.

3. The boot time take 10-15 longer. It hangs at the ASUS splash screen for longer than normal.

4. Sometimes, the SSD will not even be recognized by the bios and I can boot into windows. Clearing the CMOS via the jumper seems to fix all of these problems, assuming that I don't overclock the RAM again via XMP or manually.

Running the RAM with the OC Tuner set to Auto instead of XMP or Manual seems to net the most stability. The boot time is around 15 seconds and my computer doesn't turn completely off during a restart.

I contacted G.Skill and they don't think my RAM is bad based on the information I've given them.

However, I was curious if higher RAM frequencies in general (such as 1866MHz) could cause problems for the SSD?

Edit: Using my sig rig, by the way. My SSD and bios have the latest firmware revisions.

Didn't you have it fail memtest yesterday?

Does everything work fine with your RAM when the specified voltage, timings, and frequency are set to what they should be as shown on the box?

BIOS up to date?

No, sometimes, and yes.

G.Skill said that despite the error, the RAM looked fine. They said that the lone error was caused likely because the test was left running and they said that is typical in that scenario. Plus, the error didn't show up until the 4th pass, so they said it was unlikely to have anything to do with boot issues in that respect.

As far as working with the settings on the box, sometimes it works, sometimes it doesn't. It's true whether or not I use XMP or enter the settings manually. However, manually setting the DRAM voltage to 1.6 seems to fix this, though I still experience loss of power during restarts and occasionally the SSD will not be recognized requiring either a restart or a CMOS clear. Sometimes a restart fixes the SSD issue, sometimes not. Clearing the CMOS always seems to fix that particular issue.

However, if I have everything set to "Auto" instead of using XMP or manual overclock settings, the issues seem to disappear. My boot time is 20 seconds instead of 40, the power isn't lost during restarts, and I don't seem to experience the issue of my SSD being unrecognized (disappearing) on boot.

But, the boy problem is that I'm running at 1600MHz instead of 1866Mhz, and I'd Ike to use what I paid for if possible.

All that said, I wonder if it a RAM compatibility issue or a motherboard issue. Or perhaps my SSD is jacked up as well and it's a completely separate issue. Who knows. G.Skill said they the RAM should be fully compatible with my board and it was tested at 1.5V (not 1.6V), so who knows why I have to set it to 1.6 for more stability when I apply the overclocked settings. Something isn't right.

I ordered some Corsair Vengeance low profile 1600MHz memory to try out, so we'll see how that goes when it comes in.
