A1's the worst on mine. Sometimes it wiggles so badly I fear for the solder joints.



I don't think so. They're single latch, so you've got to make DAMN sure modules are nested well on the fixed end.

Yeah I noticed that on mine it wiggles on most of the dimms but I would either use compressed air can or use brake cleaner to really clean out any trapped dirts or sticky residues in the slot. As for the wiggle problem it to do with the tall plastic bit that houses the latch it where the ram slides into has gotten wide due to wear and tear or abuse which resulted the wiggle problem.The method I used to fix the issue is a small nose pliers and pitch the tall bit that facing the dimm slot just abit nothing too aggressive so it can close the gap to reduce the wiggle or fixed the wiggle issue all together

AHAHAHA, Oh boy... So you won't believe this method to solve my problem

Hope this makes sense. So a little history, every now and then my wife accidently presses the power button not knowing I have it in a sleep state to turn the PC on, this error's the PC and displays a black screen instead of actually waking up forcing me to hold the power button down to manually shut it down and cycle reboot till it posts. When it eventually posts it brings up the boot screen with "overclock failed" and I have to reload the OC profile to carry on as normal.

So I got thinking, removing the CPU like @Edwired suggested is kind of going to do the same thing, clearing the memory buffer and force me to reload the profile upon successful CPU install (not sure if clearing the CMOS is the same thing?) But anyways, forcing the overclock to fail and reload the profile did it for me and brought my DIMM's back to life and in full triple channel. The x58 platform really is like a classic car, sometimes you just need to thunk it good with a wrench and it'll do the trick.

Hope this helps some people, these are the additional settings I run within CPU configuration under Advanced in the BIOS:
*Note I have the C-states/tech disabled which likely allowed this error to happen for me
C1E Support: Disabled
Hardware Prefetcher: Enabled
Adjacent Cache Line Prefetch: Enabled
Ordering: Modern
Intel® Virtualization Tech: Disabled
CPU TM Function: Disabled
Execute Disable Bit: Disabled
Intel (R) HT Technology: Enabled
Active Processor Cores: All
A20M: Disabled
Intel (R) SpeedStep (TM) Tech: Disabled
Intel (R) C-STATE Tech: Disabled

That great to hear SeanBeanDiesInTheEnd
Try rebooting it a few times to see if the problem don't come back.
Make sure the power management is set to sleep for the power button instead shutdown

7 reboots so far and no issue yet Loads my eco and gaming profile's steady, bumped the DRAM bus voltage to 1.6v like you said, just to be safe while I have control over it.

Awesome to hear glad you got it sorted

 

[lexluthermiester]

I wish. I just keep rebooting til it's there and go on my merry way.

Bclk or RAM voltage issue?

 

[Mr.Scott]

Not sure if this one’s for me, but if so my 3.8 is 19*200, what value do you suggest?

I would try 21 x 181 for your 3.8

 

[SeanBeanDiesInTheEnd]

I would try 21 x 181 for your 3.8

What advantages come out of this config if you don't mind me asking - other than the high bclk causing dropped channels you mentioned earlier. If I recall from @Binge practical guide the higher the multiplier the more voltage you need for the ram

Edit: for the 920 I believe the highest multiplier available is x20 (x21 if allowing turbo). I have TM disabled in the BIOS, would this cause any problem?

 

[Toothless]

1.7v and 160 bclk, so neither.

My bad. I forgot you were on a 920.
In answer to your question though, some boards/CPU's just plain don't respond well to high bclk. 200 or better is usually an exceptional board. Voltage doesn't mean that much as long as you can keep it cool.
I was just giving you another avenue to try.

As I remember I believe I could push up to the 212 on Bclk with the 6core Xeon E5645 and OC that CPU up to the 4,2Ghz and that was the only way I could reach that "speed" as @E5645 didn't have good multiplier.....Mobo was Asus p6x58d premium.....

Good explanation

 

[lexluthermiester]

1.7v on RAM?!? That IMC must be roasting!

 

[Toothless]

Has some good cooling on there. I honestly had it there because of the last kit was just garbage, might be time to drop it.

 

[lexluthermiester]

might be time to drop it.

Oh would I recommend that in a hurry! That is a dangerous amount of voltage for any 1156/1366 CPU IMC...

1.65v, my bad. Dropped ram clocks to 1280mhz and 2/2 booted with all ram. Something tells me the board in general doesn't like more than 1333mhz.

Are all the DIMMS identical or at least the same rank(1 or 2)? If so do you have all of the DIMM slots populated?

It's a mix of 4GB G.skill and 2GB corsair.

All banks populated. So far every boot is successful.

Are they evenly populated, IE 3x4gb+3x2gb on both CPU's? Do you have any issues when you take all of the 4gb DIMMs or all of the 2gb DIMMs out and just boot with one type?

 

[Toothless]

Yep and above 1333, yep.

 

[lexluthermiester]

Yep and above 1333, yep.

But with all of them installed, you only get 1280mhz? That is so weird. Have you considered buying all matching 2gb or 4gb DIMMS? IIRC, that SR2 should be able to do 1866 flawlessly.

Tried with just the 6x4GB 1866 and still had issues. Figured to go with more at 1280.

That is very strange. Perhaps it's an oddity with it being dual socket..

ES chips, dual socket, I don't know at this point.

 

[lexluthermiester]

ES chips

Ah! There's the missing variable in this equation. Engineering samples, while generally stable for everyday use, do tend to have quirks like this. Perhaps the IMC's on them aren't quite perfected in that revision of the dies.
