"-> Pretty much I have been struggling with all 6gb not showing up on cold boot (after comp has been off 5+ hours). " 

Tbahre,  That pretty much summarizes my problem, and that of many others.  Don't spend your money unnecessarily.


It is about time for EVGA to STEP IN and further investigate a potential widespread mobo issue.

The issue is obviously not Windows nor other hw, and the only thing we have all in common is the same UBERexpensive motherboard...

Why won't EVGA do the right thing is beyond me.



@Ghost.  Thanks for your response. Appreciate it.  I have verified all my settings are correct.  This is obviously a mobo issue and EVGAs fault.  I know you don't seem to want to hear that, but the amount of cases with exactly the same issue should be a clear proof by now?

You seem to be connected to EVGA, could you please raise a flag...

My calls to support have been dismissed as a user problem and are a waste of time.  I mean, **** do I have to do?  To go and stand day and night out of EVGA's headquarters?  EVGA should understand that some of us are under a lot of pressure by our own customers.  And we are to blame for trusting EVGA products.  My customers want a product that works, and they don't care about my stories with EVGA's incompetent support.  We need to get the attention of their development group.

I want to report that I am having the EXACT same issue as the last poster. I have 6 gigs reported in Win 7 64-bit with only 3.99 usable. I'm following this thread closely to see if anything comes of it. 

specs:

Evga x58 mboard
3 x 2 gig gskill dimms
i7 920 

I'm just about to open a support ticket myself over this but as you say harry no one wants to listen, its just a major headache. I have stuck with evga for awhile now because of their excellent support but this is making me doubt things. We need answers!

Wow this is quite an informative thread. I'm glad to see that I'm not the only person with this issue.
I would be extremely grateful if you guys could assist me with my case...

A description of my problem: 
-> Pretty much I have been struggling with all 6gb not showing up on cold boot (after comp has been off 5+ hours).
-> My daily routine has become something to the effect of:
1) getting home from work after 8hrs of being away

2) power on comp (I notice that POST screen shows 4gb as it quickly zooms by)

3) let it boot into windows, see that only 4gb of my 6gb are showing even though windows reports "6gb (4.99 usable)"

4) Now I need to stress that when I say shutdown from here on out that I am indeed referencing doing a shutdown via selecting it in windows. The same goes for restart. With that out of the way if I continue to sit in windows with the 4.99gb usable showing I will get a blue screen within 30 minutes. Many times they are the "IRQL Not Less or Equal" blue screens, sometimes others.

5) At this point if I restart the computer after booting into windows and seeing the 4.99gb usable out of my 6gb it will continue to show "6gb (4.99gb usable)". I can restart 100 times and it is always the same. BUT BUT BUT....

6) ...If I do a shutdown then wait a couple seconds and hit the power button I can see all 6gb post as the post screen zooms by. Once I'm in windows it tells me that I have all 6gb available to me and everything works awesome for hours and hours with no blue screens or problems what-so-ever.

7) Bed time comes after having the comp on since I got home from work so I shutdown. Rinse and repeat the next day.


Lets move on to the solutions I have tried that HAVE NOT WORKED
- Reseated cpu and heatkiller waterblock making sure to tighten the back-plate and waterblock properly eliminating any possible problem with the board bending from over-tightening both parts.

- Checked for bent pins and cleaned the cpu socket with a can of air 


            - Tweaked voltages over and under auto amounts    - What voltages? can u Specify


- Tested each ram module separately in each slot to eliminate the possibility of bad ram or bad slots.

- Tweaked overclock settings from stock up to 3.4ghz

- Tried ram at rated 6-7-6-18 @ 1600 timings as well as underclocked

- Changed mem lowgap setting


           - Tried to force max memory via msconfig.exe    - Leave this unchecked (max memory)


       - A few different bios from old to the newest (49) which I am running now.   - Here is what I picked as my favorite so far S21H and S22D. haven't try any above last one cause have no need to everything is tiptop. However don't hold me to this. :) just remember, I have 759 Classy. I don't know if it makes a difference, I doubt it however.

- Will update if I think of anything else I have tried in the past 2 months.


Things I HAVE NOT tried yet
- Stock cooler, but since I have made sure my waterblock is not exerting excess pressure on the socket whats the point? I guess it never hurts to try though.

- Different brand of ram. This is where money becomes an issue. Whats the point if my current ram is functional?

- Different CPU. Money is a problem here as well but there is no indication that it's bad.

- Different power supply


         - Baseball bat to the dimms and cpu socket area.  - I love this one. Good sense of humor is always a positive sign. But referame yourself from this one.  LOL.



- Feel free to add more in this department for me if you see fit.


Possible Solutions?
Well tbh the only thing I can think of is something changes with heat after I power on the system but if this were the case then wouldn't one of those restarts fix me right up?

Edit: Within the last 5 minutes here I have done some brainstorming. When you do a shutdown the power supply power cycles off and on vs. when you do a restart the power supply stays on but the system just restarts. Maybe this has something to do with it?


System loadout:
Mobo: E760 Classified bios 49

Thank you for your trust. But I have to disappoint you. Im not connected to EVGA, Im not a representative, affiliate or anything else beyond being a customer. My opinion is fully based on my personal experience and information obtained through Internet and this forum.
I started this thread for the same reason you all post in here. I had the same problem. I found one of the solutions. That's all. I was just hoping If people experiencing same type of issue, we can keep it in one thread and through out the time come up with multiple solutions.

                 If I wouldn't want to hear about the problem Id just let this thread go. If you would google this issue you would be aware that a problem is frequent to all vendors Asus, Gigabyte, etc. So that's why I said its not likely to be the board. IMC in your cpu tests the ram on POST. There is a post by Shamino  in this thread, where he explained how it works. any speed above 1066 is overclocking. some ram rated for 1333, but most ram is 1066. So its all a crapshoot with Memory. Some IMC can take overclocking realy well some not. Some ram works at what manufacturer says it will, some dont. There are people here asking all the time - "O whats the best memory for me?" and there always be  - "Such and such is good"  but the next post will be - "No that's crap use this and that". To as many who'll say this one is good there will be just as much who'll say its bad, and vice-verse. So it might take you two or three sets of different ram to get it right.
Most vendors carry good RMA policies and warranties. I prefer lifetime myself. So it wouldn't be a problem. Another good thing is to order two sets right away and keep the one you like (works) best (30 refund policy with most etailers).
As to raise a flag. this thread by itself is a flag my friend. You can always PM a mod if you think that this deserves a better attention. Im sure that they quite aware. Ill try to PM Jacob to see if he can voice his opinion on the matter.

Well here is something interesting in my situation... Last night before I went to bed I set my memory to 1066mhz. I booted this morning after 7hrs of having the comp off and it is showing all 6gb on the first cold boot!!

Thing is, I don't want to run my ram that slow. I would like to run it at its rated 1600mhz.

Knowing this new info, does this mean my problem is the result of a weak IMC on the chip? Should I get my hands on another i7 920?

Im glad it works. My answer to you try to keep runing your Ram at 2:8 divider Which is you probably used this morning. it keeps it at 1066 @ post. Remember your ram is always Bclck * ram divider  * 2.  So if you run 200 BCLck with 2:8 ratio you ram is at 1600 though at post youll see 1066. Mine boots at 1333mhz but in windows its 1866  (2:10 \ 187 bclck).
Can you post your voltages from your bios that you ran of this morning, the one that worked. here is the link. http://forums.evga.com/tm.aspx?m=1430 and the one that was causing your RAM disappear. Thank you.

Just to let you know I had this problem before and corrected it by shifting my cpu.  After reading this thread I went and tried to lose memory total on two different boards (both x58 760) and two different cpu's (w3520, w3540) and was able to lose memory total  by shifting the cpu's around. If you take a look there is a little play in the cpu socket and just enough to give you a problem. On one of my boards it was very difficult to lose any memory but was still able to duplicate the problem. So if you haven't tried to re-seat the cpu, try it it and as others had suggested over tightening can cause a contact problem also.  Also check to see that all the pins in the socket are not bent, very easy to with the design of it.
 
Bios E760 - 43

I'm in the very same boat....maybe this mushkin ram aint soo happy with the evga board?

TBahre
Today I did my cold boot and waited for the post screen, saw that only 4gb posted out of my 6gb so I entered the bios. Once in the bios I powered off the system manually. I Immediately powered on the system again and boom... there are my 6gb at the post screen. This is starting to seem bios problem to me... because no matter what, that second power-on will get me my 6gb.

Hey guys, I'm having this problem too and it seems to me like it may be bios issue as well.  I'm running a X58 with 9gb of OCZ Platinum on mostly default settings (very little changes to the bios except for ocing the blk).

I just flashed the X58 latest bios update a few days ago and it may have started to occur before I found out but today I cold boot and it shows only 3gb usable.  I'm going to do a quick clean to get rid of dust and hairs and then swap the ram sticks around to see if that makes any difference.

I had no problems whatsoever prior to flashing the X58 bios so I'm kicking myself now for having updated.  Has anyone tried flashing to a previous bios update?

Ok, I just reverted back to bios SZ21 and all is back to normal.  As soon as I reboot the bios was showing 9gb instead of the 3gb with the latest bios.

So for anyone who's having problems and pulling their hair out, just revert back to an older bios (one that you know works).  I wish EVGA would come forward and address this issue.  From the rising number of posts regarding this issue, they should at the very least provide a simple troubleshooting guide or update the bios changelog to reflect current issues.  Would have saved me a couple hours as I surely would not have updated the bios had I known about this earlier.

Maybe we should compile a list of bios' that do not suffer from ram disappearing.

Yes, this is a permanent fix..at least for me it is.  I'm sure if you went back to an older bios that you had everything running smoothly on it would be a viable solution.  If you still having issues after reverting, then I suggest testing each stick of ram one by one.  No way to really tell if there's an issue with the board unless EVGA comes out and says so.

I updated my BIOS the other day for the first time in 6 months or so. put my setting right, and didn't think anything of it. The next day I noticed a lot of disk thrashing when I started playing WoW and noticed my memory was being used. I couldn't understand what was taking 6 GB of memory. I always had a couple of gigs left even when playing WoW. As I am taking a close look tonight, I see that I only have 2 GB available out of the 6 GB. It wasn't until I found this out that I started troubleshooting the issue. I plan on going back to an older BIOS and seeing if that fixes the issue as it didn't crop up until I upgraded. Tooooo much of a coincidence if you ask me.
 
I'll post my findings...

Update... So, in the wee hours of the morning, I downloaded an older BIOS and flashed it from within Windows 7 using the flash tool. After a reboot and reconfiguration of my drive settings, I was able to boot back into Windows and voila, 6 GB of memory detected AND available.  So yes, in my opinion the latest BIOS breaks something and the full amount of memory does not appear as useable to Windows. After I downgraded, I logged into WoW and no more disk thrashing because of low memory errors. I have not flashed back to the current release to see if the issue returns. I've got a raid tonight and don't want to be missing out because of this issue. :P

I'm in the very same boat....maybe this mushkin ram aint soo happy with the evga board?

maybe... these boards seem extremely picky with what they like.

BTW Ghost I tried both your bios temps and had zero luck so yesterday I tore down my CPU waterblock again. Took out the CPU and went over the pins and socket with a fine tooth comb again. Found no problems again. Look at all the again's lol.

Anyway, Since all the items in the socket appear good to go, I inspected the CPU itself. Taking note of the locations of the dimples where the pins make contact with it. I would say that 97% of the pins are making excellent contact, 2% are contacting on the edge of their area for contact but still ok, and as for the rest which is only 1 contact point that I could see which was missing making contact.

As I said in my original reply in this thread my system runs 100% perfect when I shutdown immediately after the cold boot and then power back on, so that one pin missing making contact isn't causing issues.

Today I did my cold boot and waited for the post screen, saw that only 4gb posted out of my 6gb so I entered the bios. Once in the bios I powered off the system manually. I Immediately powered on the system again and boom... there are my 6gb at the post screen. This is starting to seem bios problem to me... because no matter what, that second power-on will get me my 6gb.

Im sorry to hear that it didn't work for you. However the problem is so widely ranged so Its hard to PIN point it. Lol.
I hope you'll be able to find another cpu to try. You mentioned that you tried bios switching, Try the ones you didn't yet.
You also mentioned this one pin that not making a proper contact with the cpu. Did you tried to straiten it out. If not I would recommend you to do so. Even a one missing pin can cause a hoax. I hope you understand that Im trying to look at it from any direction possible.
Can you confirm that you don't loose any ram at stock everything but ram volt at 1.65  (if the ram is missing at stocks than it is one out of
- Bent Pin, CPU, Board, Ram, Bios) you said ram checks outand you checked your pins. If its present at stock then try to drop your overclock down couple of notches. See if it'll bring your ram back.
Edit" I see you tried down-clocking  it already."
Maybe look through the thread again. See if you missed something.

EVGA, prettly please with sugar on top, look into this deeper!

Thank you for your post. I glad to see that it worked out for you. I can confirm that A bios can case the issue sometimes. I found that only two older bios's worked for me. Im stable now for a long while on the s22d. But for some, unfortunately it didn't work.
I searched the web for the issue again. And can state that the problem stands with almost all boards manufacturers of X58 P-H55, However most common answer is Bent pins. In other cases its bios at fault. I would not exclude board, poor overclocking and faulty Ram as well. The IMC is quite picky with OC ram.

Hi all,

I just want to add that since 2 days I am having the same problems discribed here!. I have x58 and 3x2 gb. I ometimes have only 2 gb and sometimes 4 gb usable!

And needles to say I flashed 49 bios 2 days ago? I also started noticing memory problems in games and said ****!

I will try to revert bios back ....

Will post my findings. 

EVGA please do something....... My PC was running great for past 1 year without problems.  !$#%@#$$ pins and bad RAM ....

Best,

TBahre

 The thing is, of course one stick registers through at a time because this problem only occurs on a COLD BOOT after 5+ hours of being turned off.

Apologies.  I haven't read this whole thread, and I don't have this problem.  Yet.

It looks like it would help your troubleshooting if you could duplicate the situation w/out the overnight wait.  If it is temp related, this won't help.  If it is starting from a fully "discharged" system, it might.  Shut down your machine, turn off the AC mains.  Hold the ON button down for 10 sec.  Fire it up and see what happens.

I've had several machines that somehow remember state when powered off for a short time, but clear themselves overnight or if the above little dance is done.

If you've already tried this, or if it has already been suggested upthread, sorry about the noise.

Z.

I have the same problem with my mushkin 6gb 1600Mhz redline kit. I can only get 2gb of memory in BIOS and Win7. However, after testing each module one by one I have found out that system won't boot with one of the sticks installed. After leaving only 2 modules plugged in to the controller I get correct 4 Gb in BIOS and Win7. So it looks like the issue is more complex and there's many causes to the same problem.
Hope it helps.
