    Hi Mick,
    I've tried 1GB and 2x2GB and the voltage was set 1.76V on auto as well. And that 1.76 is real voltage (checked with Everest). In my signature 1.7V is used for different ram (HyperX) - that's the one that replaced KVR1333D3N9. (I've used 1.5V instead of 1.76V before). Since you've got 4 sticks, 2 HDDs, 2 Optical maybe you need to raise MCH voltage to 1.30V to boot using 1.5V ddr voltage. Or try 1.6V but not 1.76V.

    Hi Comers,

    Thanks for your reply and advice. I tried MCH Core 1.28 with DRAM 1.58 - Ended up with BSOD and a corrupted Vista 64.

    Then tried MCH Core of 1.3 with DRAM 1.5 - same scenario.

    Rebooted with MCH Core 1.28 and DRAM AUTO - System up & running again. Check ET6 and the AUTO DRAM has voltage sitting @ 1.76 again!

    It's all getting a bit beyond me!!!! I can't really afford to go out & purchase another $400 or so of Hyper DDR3 like yours. I've got 8GB because I do a lot of video editing & multitasking. It's a bit annoying when I'm using Gigabyte 'approved' DDR3 for their MoBo and their MoBo want's to run it at 1.76V, or not at all.

    Hi Mick,
    Looks like now you are able to boot. So try this in that order:
    Unplug your power for at least 30 min. Then power up and enter BIOS immediately.
    Load Optimized Defaults, Change DDR Voltage to 1.58V, save and reboot.
    Enter BIOS again (don't let vista start)
    Performance Enhance: Standard
    Manually Enter the Main memory timings: 9-9-9-24.
    Go to Advanced Memeory timings and set Static tRead Value = 9 (later try 8).
    Command Rate (cmd) set to 2
    MCH Voltage: 1.28V
    Save, reboot and start vista.
    If you get BSoD again then go back to BIOS and change memory frequency to 1066MHz by changing SPD multi to 3.20B. Why? I've moved KVR1333D3N9/2G to asus P6T Deluxe V2 board and by default it was set to work on 1066MHz instead of 1333MHz. And I've never seen crash/freeze on the asus board.

    Hi Comers,
    No joy with any of your suggestions - BSOD erery time!

    I took the PC back to MSY and spoke with on of their Techs. He was extreemly helpful. He said I woiuld have been better with the EP45 board instead of the T. They've had problems with DDR3 and my board, however the thought it may be a problem with the sticks, so he swapped them over for me. So far, so good. It's been just over 243Hrs without a freeze or crash.

    I was looking at swapping the DDR3 over to G.SKILL, but he wasn't able to do that because I no longer had the packaging for the Kingston. I have read other posts from Torin who's had the same problem as me with the same board. He's also tried Crucial & G.Skill DDR3 1333 - all with the same problems. So I don't know if it's a 1333 thing or not? I'm tipping given that I couldn't get mine to POST @1066 either I'm thinking maybe just an incompatibility with Kingston KVR DDR3.
    I assume yours has been fine running the Hyper X DDR3?

    Assuming the Hyper X is a known quantity and my problems persist, I might just have to shell out more bucks for 8Gb of Hyper X - maybe 1600!

    I'm getting nowhere fast with either Gigabyte and Kingston. Instead of assisting the customer (ME) their too busy playing the blame game and handballing it to one another! I would've been wrapped if Kingston allowed me to upgrade to Hyper X and return my KVR - I would've been glad to pay the difference. I couldn't do that at MSY because they don't stock Hyper X.

    Hi Mick,
    I have bad news as well. Even with HyperX my EP45T freezes now :(
    Looks like after all EP45T have memory problem. Anyway I'm switchig back to my X48T board that never had issues either with KVR1333D3N9 or KHX13000AD3LLK2 and will RMA this EP45T again but his time will insist on replacement with rev1.1. or the ddr2 model.
    Although now HyperX costs 3 times less than in December'08 I would recommend you NOT to buy additional memory until you get replacement.

    FYI. I had problems when I installed Crucial, OCZ and Corsair RAM in my X48T-DQ6 board a year ago, the common restart loop. They were 1.8v DIMM's and never wanted to BOOT to the 1.5v default MB voltage.
    A very well known member here suggested I try Mushkin. I purchased the 2X2GB HP PC3-10666 kits (1333 MHz), pt#996652.
    They never failed to BOOT at default voltage and have been very adjustable. I was even able to run them at CMD 1T.
    My X48T board had a lightning strike a month ago. I purchased a EP45T-UD3P board and used all my hardware including the Mushkin DIMM's.
    Again, the Mushkin will BOOT to default 1.5v on my EP45T MB, without fail. This is very comforting knowing that if I need to FLASH the BIOS, my board will not fail on startup increasing the possibility of a bad FLASH.
    After initial BOOT I can enter setup, tighten the timmings 7-7-7-20 and bump the voltage to 1.7v. I have never had a restart, freeze or shut down problem.
    You can find Mushkin at all the popular online e-tailers. If your in the US you can buy from Mushkin direct. Compare prices, if Mushkin direct is not less, I can share a little secret to get an additional 10% off.

    Hi MDDI,
    Thanks for your post. My EP45T-UD3P, as you've probably read here, will only run with DRAM [Auto] 1.76V with my Kingston KVR DDR3. So far I'm on my second Motherboard and second lot of DDR3, still with the same problems. Clearly the MoBo doesn't like the DDR3 or vice versa. How long have you had the EP45T running solid on the Mushkin DDR3? This might sound like a solution...... finally! Pity Gigabyte state the Kingston DDR3 is 'supported' when it clearly is not. I'm in Australia, so if I'm looking at Mushkin, I'll have to get it from the US and shipped over. I've never heard of the brand here. Any info you could give me re a cost saving would be greatly appreciated.

    Regards,

    Mick

    Hi MDDI,
    If you purchased your EP45T-UD3P a month ago probably your mobo is Rev.1.1 and ours are Rev1.0. Is it so? I had mine back in November 2008.

    Hey,
    My EP45T is a rev 1.0, BIOS flashed F7. Must have been an older stock MB I purchased from Newegg. I have been running it for two weeks with the Mushkin RAM, "no" issues and I have tightened them up.
    My Mushkin's are rated 1.7v - 1.8v, but they BOOT and are stable at 1.5v. I believe I could leave them at 1.5v and they would run just fine. I currently have them at 1.7v.
    Mushkin is one of the first companies to manufacture RAM in the US many years ago. I have heard that they do not have much of a distribution network overseas.
    I had never had real RAM issues until DDR3. All the MB manufacturers default DDR3 RAM voltage at 1.5v and most performance RAM stock voltage is higher, regardless of brand. Hence the problem, read other MB forums, same issues. I don't know why the RAM manufacturers and MB manufacturers don't get together on a DDR3 standard? But, actually they have a standard, if you follow the unwritten rule and put 1.5v DDR3 RAM in a DDR3 MB, the RAM usually is fine.
    Most of us here are performance minded, so we buy the "better stuff" and the snake raises its' head. Look at the i7 DDR3 Tripple channel boards. The standard is "very" voltage specific and we don't hear as many RAM issues.
    I do not pay much attention to the RAM QVL list whether it's Gigabyte or other. Look at a couple different DDR2 and DDR3 MB RAM QVL lists. I beleive you will find them the same when you compare. It's a catch all. They test one board and share the list throughout. I'm pretty shure they are not testing each board with all the RAM on the list.
    As a rule of thumb, I match my RAM frequency with my CPU frequency. Mick, your CPU is 1333MHz, so I am 99.9% positive the same RAM I have will run in your board, pt#996652 (2 X 2GB kit).
    Mushkin makes Ascent, Redline, XP, HP and EM in their performance line. I use the HP. I believe they are all the same chip, just hand picked for tighter performance. Your splitting hairs, the performance gains between them are not that noticeable to most of us.
    There are several etailers in the US, one is, Newegg.com - Computer Parts, PC Components, Laptop Computers, Digital Cameras and more! Technology content trusted by users all around the world :: TweakTown that sell Mushkin. You can also buy from Mushkin direct. Compare prices and buy from the lesser expensive of course. During checkout on the Mushkin site, if you type "TECHARP.COM" without the quotes in the "promotion code" box, you will get 10% off.
    Not sure about overseas shipments? If you have a problem, I will, as I'm sure many here would purchase for you and forward.

    Mick,
    I forgot to mention. When you populate all the DIMM slots, the world changes. You may find that you will have to BOOT and enter setup with two DIMM's, change your settings, shut down and add the remaining DIMM's.
    I'm not sure the TweakTown site will let this link come through. It is an older article about Vista and RAM, but well done. You may re-think your RAM requirements after reading.
