Hi!
I just bought my new computer with following components:
Gigabyte X58A-UD5 rev2.0
I7 920 D0
Scythe Mugen2 revB
3x2GB G.Skill Ripjaws 1600, 8-8-8-24 http://www.gskill.com/products.php?index=235
XFX 5870
XFX 850W power supply
Creative X-Fi Titanium
Intel 80GB SSD, WD and Samsung 1TB drives
Windows 7 Ultimate 64bit
I have big problem with my RAM. Already tried original BIOS - FA, F9B, and F10.
Memory is sometimes recognized as 2GB sometimes 6GB, and mostly as 4GB. Programs like CPU-Z, Everest and others list all three modules as present and working. Windows says that there is 6GB and only 4 is usable.
Nothing is overclocked.
Tried setting RAM as auto (which gives 1066MHz), and tried XMS profile which gives 1600MHz and 1.6V. Also tried rising VTT voltage.
Also tried changing memory stick to different slots.
F9B BIOS has most troubles - after verifying pool data... gives Recovering lost DRAM size and reboots few times until it manages to start Windows.
F10 beta BIOS mostly gives me all 6GB of RAM but is rather unstable.
So back to FA and 4GB of RAM. CPU idle temp is 38'C.
Please help me...

I know that you have been getting all sorts of readings of differnt sizes but there have been several reports of bent pins on the CPU socket with this type of problem recently so you might want to check that first.
-
I checked pins, also photographed them in macro mode and then previewed them on my computer and they all seem to be ok.
-
That's ok then but it was worth checking in the light of recent events. To be honest all the things I can come up with you seem to have already tried, like upping the voltage and using XMP setting. How high have you gone with the voltage setting? There is certainly many instances of this happening recently.
-
I upped VTT to 1,3V, RAM to 1,64V and all other one or two notch up. How come that different bios versions give different behaviour?
-
They tweak the settings in them to help make things work better or more compatibly.
You could see if there is any newer updates on TweakTown( http://forums.tweaktown.com/ ) the US version of our forum. They tend to get the beta versions first.
-
Have just checked the website for your memory and the manufacturer doesn't certify it for use with this motherboard. There may well be a reason for that. Did you not check before purchasing it? Neither does Gigabyte have the RAM on their QVL.
-
There was no other options when I was buying components, and this memory ought to be compatibile whit almost every board (based on other forums and reviews). It is certified for whole range of Gigabyte's X58 boards, so I tought it shouldn't be a problem.
I also tried loosing CPU cooler a bit as stated on one forum. I have a feeling that this is BIOS related problem...
-
It's always possible that a future BIOS update could make the board and memory more compatible but that is a bit of a gamble. Was any of the updates on TweakTown any good?
-
I checked Gigabyte's memory compatibility list and I can say that they really put so little effort in it. They tested few low end RAMs and that's it. I can replace this g.skill for few models from Corsair and Mushkin but none of them is on the list. And I would have to pay 20% more.
Which TweakTown updates you had in mind?
Btw. thank you very much for your help. I saw earlier on this forum that you are most helpful member.
P.S. Do gigabyte's techs ever look at this forum? :-)

Thanks for your kind words but there is no need. I am probably just the saddest member with nothing else to do ;)
Gigabyte do have a member of their staff who acts as moderator on this forum called "runn3R" but he is on holiday at the moment.
Memory wise I would think that you would be better off with some Corsair RAM. I am running the UD7 board and am using Corsair Dominators 1600 and have them set to XMP with no problems at all. The kit is named TR3X3G1600C8D.
Regarding TweakTown I was referring to their BIOS updates. They are often newer than ours(beta versions) but sometimes can be usefull.

I'm new to this forum but have been folowing this thread (and others like it) for several days now.
In my case, I'm using a GA-EX58A-UD3R (rev2.0) motherboard but am experiencing the same problem.
Something that is interesting, though, is that this is the second one of this particular model which has exhibited the same problem for me (the first was replaced by the dealer after a day or so because of a fault but, during the periods it did work, it had the same problem.)
My new motherboard sometimes shows 12 gb after a cold boot but in most cases, it shows that slot 6 memory is not usable (irrespective of how many times I shuffle different memory boards around, it's always slot #6).
I have checked the motherboard pins but, as per above, this is the second board which has this problem so I don't believe that's the issue. This problem appears to be extensive across a wide range of manufacturers but always with an X58 chipset. I am of the opinion that this is an X58 related issue rather than any hardware fault. I suspect that an updated BIOS may ultimately resolve the problem.
I tried the latest beta (FB11) and immediately after the DMI posting, a message appeared along the lines of "Recovering lost memory size" which gave me the impression that they might finally be on to something with this new BIOS. Unfortunately, it immediately rebooted after this message and did the same thing over and over so I had to revert to FB5.

I quite agree with your statement and have come to the same conclusion myself. I am sure it is a problem with the X58 chipset as it is occurring far too often to be down to anything else. Unlucky with the BIOS update sounded promissing there for a moment. Might be worth trying clearing the CMOS first and then running the new BIOS. But it at least sounds like they bare trying to address the issue.

Hi mate,try latest beta BIOS FB16 (http://www.fileden.com/files/2009/12/20/2696817/x58aud3r.fb16.zip). ;D

Hi ex58, Does this update cure the problem?
-
I checked pins, also photographed them in macro mode and then previewed them on my computer and they all seem to be ok.
Can you post the pictures please.
-
OK, here are pictures of CPU socket. I hope you can load them http://profile.imageshack.us/user/nvarga at 2010-08-06
This is what I have been doing so far:
1. in BIOS FA loaded Optimized settings, saved, reboot
2. QFlash Fb10 BIOS
3. Loaded Optimized settings, saved, reboot
4. Set manualy many setting (later in post), saved, reboot
Now it recognizes 6GB of RAM. Boot into Windows, tested, OCCT, it works.
Tried to sett recommended memory settings which I found here (tRC=tRAS+tRP, and so on - expert memory settings) which gave me BSOD in Windows immediately upon showing desktop - BSOD says Memory Management fault.
Changing all settings, nothing helped only loading Optimized settings, new flash with Fb10 BIOS, again Optimized, and then setting values manually. Now it seems to be working. I have to say - I replaced my old Asus Commando 965P and E6600 because it started to behave badly after 3 and a half years, so I decided do buy me a shiny new toy, but this what is happening is far beyond my wildest dreams. If I knew, I would have bought AMD.

Pictures are huge in file size, lol.
Any chance of making them smaller so I can download them, lol.
Any pics of the whole socket in view from straight over the top of it? With lower f-stop to thanks.
-
From the pictures that you took all the pins look alright.
-
I have now tried ex58's suggestion and installed BIOS FB16. After 5 hours of operation and three deliberate reboots, the system is indicating 12GB all the time. This is very encouraging although, with years of experience, I'm not yet 100% convinced. What it does show is that without any reseating of memory or CPU, the BIOS upgrade alone has caused the system to now see all of the memory. This appears to support my original theory that it was never an actual hardware issue. I have my fingers crossed!
-
It is also my theory that this isn't hardware related, nor is memory incompatible.
Sorry I can't take new pictures because motherboard is in case and right now I don't have nerves to take it out once more :)
I can't understand why CPU need 1,268V for normal operation on stock speed? Is it because of higher Uncore frequency?
-
Now it showing 6GB. I copied every last setting from XMS profile and entered it manual and it has problems. I can't change any of settings other than these I posted. If I do, i get BSOD at log on screen in Windows.
I think that I'm going to change memory. But Gigabytes memory compatibility list is very very bad and short.
I can go for Corsair 3x2GB TR3X6G1600C9 or Dominator TR3X6G1600C8D or XMS3 TR3X6G1600C8.
Also there is G.Skill Trident F3-16000CL9T-6GBTD and MUSHKIN RedLine FrostByte, 998805.
All of these are superb RAMs as this Ripjaws that I have, they are all stated to be designed for X58 chipset (is there any difference between X58 boards except additional equipment and power phases?).
What guarantee do I have that any of these will work with my X58A-UD5?!
They all are certified for whole range EX58, but neither is certified for X58A series.
And whats difference between this two? Only in additional SATA and USB chip?
-
AS I mentioned earlier I have been running without any problems at all with Corsair TR3X3G1600C8D kit. That is on the X58A- UD7 board but there is no difference to the UD5 in the respect of the memory.
-
I think I'll go for this Dominator kit, although I don't have very good opinion on them. Used Dominator DDR2 on my last setup and wasn't very happy.
And I have to pay additional 30 USD. And what if nothing changes after replacement?
I'm very mad about it because on this last system with 965 board, E6600, 4GB of RAM suddenly I got BSODs, changed component by component and after one month of frustration, I throw it all away and bought this I7 system. And now this...
-
I flashed Fb10 again and didn't bother with stock speeds. I set bclk at 191, CPU x19 = 3,629GHz, Turbo off, C1 etc is all enabled. CPU voltage is 1,25V, VTT 1,3, RAM 1,6V.
RAM multi is x9 = 1528MHz, set 8-8-8-24, XMP off.
Only thing that is different now is QPI PLL which is 1,2V (instead of 1,1V) and IOH core 1,14V (1,1V).
System is OCCT (both OCCT and Linnpack) stable. Min temp is 38'C, and Linnfield heats it up to 78'C.
Still can't believe it. Overclocking is solution for all my problems ;)
-
Sounds like it is stable now. That's good that you have managed to find a solution which doesn't involve spending more money 8)
-
I have the same problem (6GB usable 4GB coldstart) but with X58A-UD5 rev1.0 and Corsair 6GB (3x2GB) 1600MHz PC3-12800 CMX6GX3M3A1600C9
Is it "safe" to update with a beta bios and use @bios for the update?
-
In my opinion no! Update to the beta version by all means but use QFlash not the @BIOS that works from withjin the Windows OS. It is far to risky and if something happens you are left with an expensive door stop.
-
Thank you for you fast reply!
I used Qflash for the update and all good so far.
Showed 6 gb last coldstart.
-
Great! It seems to work for most systems. ;)
-
Always 6gb on coldstart after updating bios to F6 beta so that is nice!
But I have got a few bsod after updating so I did a Intel Burn test.
After 5-10 minutes IBT reports errror, same thing with OCCT Linpack test. No BSOD, but error.
So I loaded optimized settings and went down from my ordinary OC 4ghz to stockspeed, But I am still getting errors from IBT and OCCT.
I also flashed the latest official F6 but the results are the same.
Never had any issues with F5.
Any ideas? could it be new bios that makes the computer unstable?
-
If it has only been happening after the updated BIOS then it would seem so. Was there a particular reason for the update? If not I would suggest reflashing to F5.
-
The reason was as you can read in my earlier post in this thread that bios only found 4 of my 6gb when doing a coldstart.
That problem is now gone! But as new has entered the scene :-)
-
I reflashed to F5 but my problem is still here. Random blue screens a few times a week more often when idle than on load
and Intel Burn test reports error after 5-15 minutes.
I have tried:
Reflash to F5
Memtest 4 passes
Load failsafe / optimized config in bios
But no luck.
I have not had a single problem OC to 4gHz (except for the missing ram when doing cold boot) since I built my system in april.
But after flashing to F6 my instability problems started.
Any Ideas?
Gigabyte GA-X58A-UD5 - Core I7 930 @ 4000Mhz- Corsair H50 p/p - Corsair 6GB 1600MHz - XFX5970 BE
-
I would definitely advise you to check the pins on the CPU socket very carefully as this has proved to be the most common cause of the missing memory. You will need a well lit situation and maybe a magnifying glass. If you are in any doubt take a few close up photos(macro) and post them here.
-
Could a bent pin cause my sudden bluescreens?
As I mentioned after updating to F6 my memory problem disappeared. But I got the random bluscreens instead.
Reflashing to F5 did not help to get rid of the bluescreens.
I am not so comfortable removing my cooler and CPU ( I bought the PC mounted)
Well,,,I will give it a try, just need to buy a life insurance and some thermal paste first :-)
-
As long as you are carefull there is nothing to removing the CPU. It is not at all dangerous to the person and as long as static precautions are observed to the chip either. Remove the cooler first and be carefull as it will be stuck to the CPU with the thermal compound(which you must replace on refitting). The pins are very small and not easy to see. I would advise also taking some macro images with a camera if possible.
-
I have the same problem on a x58a ud3r, 6gb 4gb usable. does not do it all the time, im using 3x2gb muskin redline 1600 ram. Last night it was 6gb, today it is 4, next time i boot might be 6 or 4, it never changes to anything else.

Well I would give you the same advice. Check the CPU socket pins but be carefull. If necessary post the pictures here and we will check them out for you. Post back afterwards.
-
Just to let you know about my experience with this issue. It may be a number of reasons, but I have a EX58-UD5 finding 10GB instead of 12 on each reboot.
I took the PC for service, they replaced the mobo with a new one and the same problem was there. After that they replaced the CPU. Still the problem persisted. Now I am expecting a UD3R for a replacement. If the problem happens with this motherboard too then there is no doubt that there is something terribly wrong with these motherboards and bigger amounts of RAM.
The internet is literally full of reports of users with the same problem. Unfortunately, most of them like me, did not have bent pins or problematic memory modules. I believe it is not random that so many people experience this issue.
-
Whilst I would agree that there do seem to be a lot of these cases around there are also a lot of people quite happily runing with a full set of memory. I know in your case it isn't down to bent pins etc but a lot of these problems are traced to that or some other reasonable explanation. If it was a design problem nobody would be able to run with full slots.
-
I thought I solved my problems... There were no problems when I used quick boot feature in ET6. As soon I initiated cold boot, everything changed - BSODs all the time. So I checked every stick of RAM in every slot and one stick gave tons of errors in every slot. Other two gave none or few errors. So i returned RAM and local dealer approved RMA and also change to Corsair (thank you guys!). Now I'm waiting for delivery. I hope that it will solve this mess. In meantime I also rechecked CPU pins and they all seem to be ok. But with so many problems, I can't be even sure my eyes are ok :o
-
If the memory was faulty that would explain your problems and so let's hope that some new good quality RAM will do the trick. ;)
-
Just for future reference for anyone suffering with the same problems as here please also see this thread:
http://forum.giga-byte.co.uk/index.php/topic,2808.15.html
-
I received replacement RAM - Corsair Dominator CMP6GX3M3A1600C8. For now it look it is working perfectly, with same settings I used before - bclk 191. Have to do some more testing but I guess that this nightmare is over :-)
-
Well let's hope so. 8)

Thank you all for your help guys!

You are welcome and if you ever need more help come back here. Of course you are welcome here even when you don't have a problem. Maybe you could help someone else. ;)
