I've had a look on some other forums and have tries updating and resetting the BIOS many times (tried rev FB, FB16, FB18), taken out the CMOS battery etc. It makes no difference whether I run with the standard BIOS, or OC settings either. Has anyone got any other ideas?
also your graphics card model and processor. cheers one80 MemberJoined: Jan 10, 2005 Messages: 439 I've found that both the BIOS and Windows are reporting only 4 out of the 6GBof RAM as usable (they both see that there are 3x 2GB modules though), which I think might be part of the same issue as originally posted. I've had a look around some other forums and it seems a pretty common problem with X58 chipsets not addressing all of the memory correctly. I've tried everything that's been suggested: - differemt BIOS (see above) - making sure that max memory isn't enable under msconfig>boot>advanced - reseating the memory - switching the slots - testing all the RAM - MemTest is only able to test the 4GB even though it recognises the 3 sticks - testing each individual RAM stick with MemTest - all OK. - manually settings the RAM timing and volts in BIOS - enabling XMP I found this on one of the forums: Over tightening or unequal pressure on the CPU socket can cause the CPU to not seat correctly. Frequently, this translates into what appears to be memory related problems because the CPU/IMC is not making proper contact with the pins leading to the memory sockets. So that's the only other thing Ive got to try... My specs are below if anyone else has any other ideas? i7-950 GB X58A-UD3R Corsair Dominator CMP6GX3M3A1600C8 6GB (3x2GB) DDR3 GB 5750 Corsair HX650 You're on the right path.the x58 is S1366, if you even have 1 or more Z pins not making proper contact then the ram is not going to get completely picked up by the IMC in the processor. Althought its true that some misconfiguration/instability can also cause the ram not to report the full quantity, it is commonly more of a problem to do with either these two things: bad cpu seating (tight/loose, as youve found already) incorrect/insufficient QPI/VTT voltage. if your QPI/VTT is running default at 1.175v/1.150v and your ram is running faster then 1066mhz, then auto wouldnt be supplying enough voltage. I think youll find an official FB bios on the gigabyte au site now for your Rev 2 board, I'm very glad you got an AMD/ATi graphics card, and not an NV card, I had a few of these rev two boards and theyre not working right (ATM, with any bios) with a few different NV card models. Later when a more mature bios is out, this problem shouldnt occur. but its unrelated to your problem anyway. In the boot (post), says "Detecting DRam Size" and reboots several times. In the 3 or 4th time, starts Windows. Have 6gb ram installed, 3x2gb, but in BIOS, shows only 4gb. Appear the 6gb (the 3 modules) but says that only 2 slots are "enabled". Windows says "6gb, usable 4gb". The modules are in slots 1, 3 and 4 (the blue one is empty). Already tested the modules one by one at slot 1 and are all ok. No overclock. Loaded optimized defaults in BIOS. Ram configs set to "auto". The problem is that Windows AND BIOS sees the 3 modules, but only left me use 2. Already checked the processorr pins for bents and seens to be ok. Thanks ex58! Just tried, but problem persists... In the @bios update software, before the bios update process, have a checkbox with the option "clear dmi pool data" UNchecked. This is ok? « Last Edit: July 08, 2011, 09:55:38 am by ex58 » Hi The first thing to try is an extended clear of the CMOS. Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors. Once done remove the motherboard battery for at least one hour before replacing it. Next plug back into the mains supply and boot. You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults. Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit. Have you checked to ensure that the RAM is running at the correct voltage and timings in the BIOS? Have you read this thread: http://forums.tweaktown.com/gigabyte/39003-x58a-ud3r-missing-memory-only-1600mhz.html Btw, try to resit your CPU and do not tight much. Check your socket pins ! I have read the 300+ posts of this thread you linked (there are some other links inside). The users have tried all brands and a LOT of different configuratiosn and have no solution... Sometimes, are all ok by a week and the problem returns... Las night, i have checked the socket pins are are all ok (i think). I have made 2 photos, but low resolution.

I will try this for now and back with the results. Have you checked to ensure that the RAM is running at the correct voltage and timings in the BIOS? Yes. Tried the correct ones and alternatives suggested in other topics. The problem don't changes. I will back with informations. Thanks all! (And sorry for my bad english writte...) Some decent photos (macro and good quality) are needed for the CPU socket pins as I couldn't see well enough to decide if there were any bent pins. 3 - Stick socket with bad contacts / deformed legs or foreign body (already found piece of peanut inside !! ) 4 - Rarely but why not : exchange the CPU 5 - Send for repair the motherboard Pierre according to CPU-Z your memory is in dual channel mode Have you tried setting the Extreme Memory Profile (X.M.P.) option in your BIOS should be under the MB Intelligent Tweaker(M.I.T.) section of the BIOS News: This afternoon i leave the MoBo battery out and took the oportunity to bring the 3 memory modules to a friend that have an computer support store. He tests and call me saying: One module sometimes works, and sometimes not. The other two modules are always ok. He tried for 5 times the suspicoius modeul and work 3 times, and fails 2 times. I bring them back and make some tests again, with that one alone, and gotcha! The module works in 70% the times, but in others don't. And, in the times that works, the problem of this topic appears... In other words: Works BAD! Tomorrow i will test with a set o 16gb Kingstons from my friend. If works ok, problem solved! Since the defective module are working sometimes, i can't detect this yesterday... Thanks all for now! I will update about the tomorrow tests. Memtest is not perfect !! Problems are > 90 % caused by bad memory sticks Pierre Possible problems are : 1 - Rams ( detected , test ok but even when bad memtest cannot test ram in all full mode ) > test with anothers sticksMemtest is not perfect !! Problems are > 90 % caused by bad memory sticks Pierre Yes Pierre. Item 1! I'm happy because, aparently, my MoBo is ok! Well, i need that ram capacity, for my audio editing aplications... Probably i will buy a 12gb kit from Corsair or Kingston, to make triple channel. If possible I would suggest the Corsair and use Dominators or Vengeance modules as you can always tighten the timings to give yourself a bit more speed. Glad you found the problem anyway! |
