Giga ep45-ud3p has issue with memory's slot

hi all
i've tested my 2 sticks g-skill 2x2g with slot 1 and 3 and i got of errors in memtest .
so i tested again 1 by 1 with slot 1 all of them passed 3 tests ,it means the memory are good!
again i put them in slot-2-4 they passed memtest 6 tests.
i've got the RMA numbers for replacement , but i'd like to know if it's worth to do the RMA because i dont think that i'll upgrade my memory to 4 sticks(8gig) .my question is there;s a difference to run the memory in slot2-4 instead of 1-3


one more thing that i dont do OC

thanks for your time

  1. What does your mobo manual say about using the odd or even slots with 2 sticks?

    Before you RMA the mobo, set DRAM voltage to 2.1V in BIOS manually.
  2. Gigabyte boards are supposed to the odd #'d slots first. Increasing the RAM voltage is a good idea.

    As far as RMA'ing is concerned, you need to decide if it is worth it. I probably wouldn't.

    No difference whatsoever!

    Have you done a "Load Optimized Defaults" from the BIOS yet? This is a pretty much mandatory step in starting up all GB MOBOs. What it does is to force the BIOS code to 'read' the hardware (especially the memory) and set the myriad 'auto' CMOS parameters; see the bottom note on page 35 of your manual - figure 2-11 on page 61 - and the fifth item in the troubleshooting guide on page 119...
  4. hi
    thanks for your replys
    yes , i;ve tried to load ( LOAD OPTIMIZED DEFAULTS)
    and about the voltage of RAM i've treis to set it at:

    but memtest freezed so i've had to change them back to slot-2-4

    do you think that i'll keep my comp working like that ,no need to do RMA?

    thanks for your time
  5. Post a part number for your RAM and I'll try to advise...

  7. A lot of this is 'canned' - so if you've seen parts of it before, skip ahead!

    GA-EP45-UD3P E8400 to 3 or 3.6 GHz
    Intel E8400 1333FSB x9.0mult 3GHz .85-1.3625V Core E0 sSpec SLB9J CPUID 1067Ah/Core C0 sSpec SLAPL CPUID 10676h
    G.Skill F2-8500CL5D 8GB (4 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 memory: 5-5-5-15-2t nominal 2.1v

    Gentle (but noticeable), no-risk, low-voltage Overclocking parameters are in italics...

    If you haven't yet done it, pull out one stick, start with a BIOS' "Load Optimized Defaults"

    Before we start ramping things up, I want to teach you a new skill involving the BIOS: Do the <DEL> at the boot to enter the BIOS; notice, at the bottom, the <F11> "Save CMOS to BIOS" - hit this, and you should get a menu that will show a number (the count varies by BIOS) of empty 'slots', each of which will store an entire set of BIOS parameters, to be re-loaded from the corresponding <F12> "Load CMOS from BIOS"; this is a wonderful overclocker's feature. What I do with it, is to save my 'baseline' working parameters, so if I change something that 'irritates' the board, and forces a reset of all the parameters to defaults, or, even worse, get so screwed up I need to do a 'clear CMOS', I can get back to my starting point with no effort, and without having to remember 85 separate settings! Another thing it prevents is two hours' troubleshooting, having forgotten a change to a crucial parameter - like, "wait a minute - didn't I have the Trd at seven?!" It's pretty self-explanatory, and I alway urge people to start right away by taking the time to give the 'slots' names that mean something: in two hours, "Try2" and "Try3" will not be very helpful, but "450@+10MCH" and "450@+15MCH" will! Another use is for 'green' settings; overclocks, as a rule, do not 'play well' with green features, such as 'down-clocking' and 'down-volting'; with the storage slots, you can set up one profile, say "Green", with all the settings at 'stock' values, and all the 'green' features enabled; another, say "Balls2Wall" with a full overclock, and all the 'green' stuff turned off... Another neat feature of this 'slot' system is, for most BIOS, the mechanism itself will keep track of which ones have booted successfully, and how many times (up to, I believe, a max of five)!

    On the "Advanced BIOS Features" page:

    "CPU Enhanced Halt (C1E)" to "Disabled"
    "C2/C2E State Support" to "Disabled"
    "C4/C4E State Support" to "Disabled"
    "CPU Thermal Monitor 2 (TM2)" to "Enabled"
    "CPU EIST Function" to "Disabled"
    "Virtualization Technology" to "Enabled" - this allows use of Win7's fantastic VirtualXp feature...
    "Full Screen LOGO Show" to "Disabled"

    On the "Integrated Peripherals" page:

    Your manual shows "Legacy USB storage detect", but later BIOS say "USB Storage Function" - either way, set to "Disabled"

    On the "Power Management Setup" page:

    "ACPI Suspend Type" to "S1(POS)" (for now...)
    "HPET Support" to "Enabled"
    "HPET Mode" to whichever OS type you're running - "32-bit" if an x86 version, "64-bit" if an x64 version...

    On the "MB Intelligent Tweaker(M.I.T.)" page:

    "Robust Graphics Booster" to "Auto"
    "CPU Clock Ratio" to "9"
    "Fine CPU Clock Ratio" to ".0"
    "CPU Frequency" - this one can't be set, it's calculated, and will change when we set the next few items...

    ******** Clock Chip Control ********
    >>>>> Standard Clock Control

    "CPU Host Clock Control" to "Enabled"
    "CPU Host Frequency (Mhz)" to "334"
    "CPU Host Frequency (Mhz)" to "401"
    "PCI Express Frequency (Mhz)" to "100" (not auto...)
    "C.I.A.2" to "Disabled"

    ******** DRAM Performance Control ********
    "Performance Enhance" to "Standard"
    "Extreme Memory Profile (X.M.P.)" to "Disabled"
    "(G)MCH Frequency Latch" to "333"
    "System Memory Multiplier (SPD)" to "3.20 B"
    "(G)MCH Frequency Latch" to "400"
    "System Memory Multiplier (SPD)" to "2.66 D"

    The strap is the reason we used a 334 or 401 clock, instead of a nice even 400: the 'straps' are sets of northbridge timings - much like memory latencies, the faster you go, the 'looser' the timings have to be... There are four straps, corresponding to the Intel FSB ratings: 200 (800FSB), 266 (1066FSB), 333 (1333FSB), and 400 (1600FSB - Intel actually does make a 1600 FSB CPU - the QX9775 - but, I think, it's over $1500 a pop!); each strap has it's own set of available memory multipliers (ratios). For instance, the 2.66 we used (which is actually a 4:3 bus to bus ratio) is available only on the 400 strap. Anyway, the strap latencies, for some northbridges, don't 'kick in' until one over the selected strap; so, in other words, setting the clock to 401 guarantees that we're getting the 400 latencies/timings...

    "Memory Frequency (Mhz)" - again, can't be set, it's calculated...
    "DRAM Timing Selectable (SPD)" to "Manual"
    You should be able to leave the rest of the memory settings alone; we haven't changed its actual speed, so it should keep working: If overclocking, we

    simply took it from a system clock of 333 (1333FSB) times a three point two multiplier (333 x 3.2 = 1066), to a system clock of 400 (1600FSB) times a

    two point six six multiplier (400 x 2.66 = 1066)

    "Load-Line Calibration" to "Disabled" (this works differently on different boards - on mine, it's worse "enabled" than "disabled" - the function is supposed to cure a phenomenon called Vdroop - the CPU voltage regulation circuit causes the CPU core voltage to sag, or 'droop' under high loadings; hopefully, we're going to be at a low enough voltage to just ignore this...)

    "CPU Vcore" to "1.2500V"
    & "MCH Core" to 1.200V" if you intend to add more than two sticks of ram...

    And that should do it!

    I should point out that getting two reboots in a row here is perfectly normal behavior; it seems that, when you change certain settings (and we don't exactly know which ones - the only sure one I know is Trd - if you change it, I think you get the 'twin' reboot) it boots once to 'see where it's at', recalculates its remaining 'auto' settings, saves them, and then boots again. Three reboots in a row, however, usually indicates that the board was 'given indigestion' by your settings, and is going back to defaults. This sometimes goes astray, and it doesn't get back into proper operation - for example, at this point, mine will sometimes 'lock' itself into 111MHz x a six multiplier - and take a week to do a whole boot - that's time to do a CMOS reset, and use your 'stored' <F12> profile to get back to where you were...

    Good luck!

  8. thanks for your time

    this is how to OC ?right

    i've 2 questions:

    1- i'll keep my memory sticks in slot 2-4?

    2-do i need to buy a cooling for my cpu, to do the OC

    because the one i have is the original fan came with the cpu
  9. Quote:
    1- i'll keep my memory sticks in slot 2-4?

    yes, if it's still a problem; after this process, unless there's an actual problem with the hardware, they should all work...
    2-do i need to buy a cooling for my cpu, to do the OC

    Yes, I would do that - the stock cooler is marginal at very best. You don't need to obsess about comparisons, or spend a lot - the cheapest thing you'll find on the aftermarket will be a vast improvement over the stock Intel piece. I often recommend ARCTIC COOLING Freezer 7 Pros:
    as they are reasonably priced, small enough to fit in nearly any rig, and will get the job done at any speed you're likely to want to go to; fact is even this:
    will do a crapperload better than the stock cooler...
  10. thank you for your help
    very appreciated

    i'll order a cooler for my cpu and i'll post back
  11. I'll be here! :sol:
  12. hi
    i'm back
    just received the ARCTIC COOLING Freezer 7 Pros
    i see there is paste on it
    so i will keep it there and just install it on the CPU ? no need for the artic silver5?

  13. I'd stick with the paste that is on it - it's been silk-screened, and will guarantee a nice, even application...
  14. One of the major benefits of the ACF7P . . . you can't go wrong on the thermal paste.
  15. hi there
    ok ihad them set like like your steps
    it reboots right away without problem
    CPUZ shows

    VID 1.2375V
    so it's a good sight?
  16. Sounds like you're in good shape! If you'd like to try 'er a bit quicker, try the italicized settings - only three changes to make:

    "CPU Host Frequency (Mhz)" to "401"
    "(G)MCH Frequency Latch" to "400"
    "System Memory Multiplier (SPD)" to "2.66 D"
  17. hi
    i went out just got back home

    "(G)MCH Frequency Latch" to "400"
    "System Memory Multiplier (SPD)" to "2.66 D"
    i changed them to this but only "CPU Host Frequency (Mhz)" : 333 dont allow me to change so i did a reboot without problem

  18. i just run prime95 it failed in 4minutes

    intelburntestv2 gave a warning after 3tests

    something is wrong ?

    the reboot is good

    ok i can set all 3 of them like you want now

    core speed: 3610.4mhz
    multiplier : x9.0
    bus speed : 401.2 mhz
    rated FSB : 1604.7 mhz

    i'll test again with prime95 and intelburntestv2 to see if there's something wrong

    i' ll post back

    thank you
  20. Run a bit faster? :sol:
  21. hi bilbat
    i let it ran with prime95 for 1h30 without errors and 0 warning

    it also passed the intelburntestv2 at standard mode

    do you think that everything is ok now?

    i'll leave the settings like that in bios

  22. You're in great shape, and your hardware isn't stressed at all - she'll have a long, happy life!
  23. hi
    i'm happy now
    very appreciated your great help
    i've learnt alot of thing over this site
    again thank you for your time

    good luck to all
  24. Always welcome...

    Have fun with new toy!

  25. hi bilbat
    i've one question for you
    because i checked CPUZ which showed the memory has 4 GB
    but in my computer properties it shows only 3.25 GB usable
    Do you think that it's normal?
    i could show you the screen shot but i dont know where is the attachment button

  26. That's simply because your 32 bit operating system 'loses' some memory to devices (primary culprit - your video card) that have to 'map' themselves into the available space (two to the thirty second power is four gigabytes...), making that memory unavailable to other programs... Nothing to worry about - the only cure is to switch to a 64 bit operating system (and I'd avoid Xp x64 - it's always been Microsoft's 'red-haired bastard' child - poor driver and overall support), which you may want to do when seven hits the market!
  27. thank you
    one more thing learned from you
  28. You can see a map of these locations on your own system, if you're interested...

    Open the 'device manager', click on 'view'>'resources by type', and go down to and open the 'memory' item:

    You will have several items like the one circled above, where the same memory addresses are mapped twice, to two different devices - for hardware pieces that have to exchange large blocks of data (like a video card), sharing a block of 'mapped' memory is the most efficient way to do it... Unfortunately, that memory is then unavailable to 'anyone else' for normal use...
  29. hi
    i'd like to show you my screen shot but i dont know how to post it in my reply
  30. That's odd - I get a "403 - forbidden" error trying to access that... I'll do a couple 'experimental' posts to try to simplify, and then post a procedure for posting images...

  41. Yup - the link is working... If you look at the "ATI Radeon 4800 series" that is 'dual mapped', to the vidcard and the northbridge, at D0000000 to DFFFFFFF, that's a quarter-gig gone right there - which, if you think about it, isn't bad for a (likely) 1 gig vidcard!
