    So if I am correctly getting the big picture here, Vtt and MCH ref are going to affect ripple on VCore.

    You must have me mixed up with someone else. I don't have an EP45T-UD3P board (I have the non T model), I never posted a CPU-Z SS, nor am I looking for any overclocking help.

    Ghost707, I believe this article may help you better understand the VTT/MCH reference. Global

    no no.. trust me, it's not just "1 PCI-E slot" different.

    The difference between the stability in UD3P & DS3R is HUGE. I own both boards, and I can say that the UD3P is a much more powerful board in overclocking. They're two completely different boards.

    I don't want to cause any trouble.....
    ....uhh....yes I do.
    FYI for ghost707

    Snip from post #11 Corsair forum thread for P45 mobos and DDR3 memory (Ram Guy, Corsair Product Guru)

    Testing done in our labs has concluded that users looking for the best overclocking results at 4GB on a P45-based DDR3 motherboard will have the best results using the following parts:

    TW3X4G1800C8DF
    TW3X4G2000C9DF
    TW3X4096-1600C7DHX

    The following part may top out at a speed short of 1600MHz on a P45-based motherboard:

    TW3X4G1600C9DHX

    =====================================
    Common sense and good business practice dictates that Corsair should make good on their guaranteed-compatible memory.
    I've provided the ammo, you get to pull the trigger.

    ProfJim,
    I have been debating on what to do, I bought the RAM about a year ago locally at Fry's - still have the packaging.
    I was considering updating the bios to F4a - maybe that would cure it maybe not. I do worry that these specific memory sticks were singled out as having problems over others - which leads me to believe that the problem lies more with the memory itself than other factors.

    Not sure how much throughput I could gain with Ram running @4 multiplier.
    With the setup I have now, I am not doing too shabby.
    What do you think Professor?

    Take a look at this testing that was done with similar ram:

    » Intel Core 2 Duo E6850 Dual Core processor (3.4GHZ)
    » OCZ Technology Vendetta CPU cooler
    » ASUS P5E64 WS Evolution Intel X48 motherboard
    » Sapphire 1024MB Radeon HD3870 X2 PCI Express graphics card
    » Maxtor MaxLine III 250GB SATA 3Gbps hard drive
    » Tuniq Miniplant 950W power supply
    » Windows Vista Home Premium with SP1 (32-Bit and 64-Bit)

    The answer my friend is pissin' into the wind .... or something like that.
    This looks similar to the ddr2 debate; is 1066 memory significantly better than 800 memory? In some ways yes, in most ways no.

    I try to buy the best hardware that I can afford at the time. That way I can do incremental upgrades without having to upgrade many components at the same time. I may be way off base, but it looks like today's 1333 ddr3 memory will shortly be like 667 ddr2 memory is today, in that any cpu upgrades in the near future will be limited with your current memory.

    OK, enough of the philosophical poop.

    The synthetic Everest benchmarks you posted (from Big Bruin) don't look terribly impressive to me. My current setup (see my sig) gives me Everest read/write/copy results in the 8900 - 9100 range, but I'm at my limit with my current cpu. If I upgraded my cpu, only then could I utilize the full potential of my memory. You'll have to see what others report for "real world" performance increases when they're running their ddr3 systems at 1600 - 1700 speeds.

    If your cpu is clocked at 500MHz, you could run:
    500 x 2.40 = 1200MHz memory
    500 x 2.66 = 1333MHz memory
    500 x 3.00 = 1500MHz memory
    500 x 3.20 = 1600MHz memory
    500 x 4.00 = 2000MHz memory
    With higher cpu clocks, you'll quickly exhaust your current ram.
    With 450 cpu speeds, the above memory figures will be 10% lower.

    Your overall performance with tighter memory timings and lower Static tRead Values (tRD or Performance Level) might be fairly close to faster memory speeds with looser timings. As an example, take a look at Lsdme's Cruicial Ballistix User Guide/Review (ddr2) and you'll see that 900MHz memory speeds nearly equaled or bested higher memory speeds.

    Bottom line, listen to what the current ddr3 owners have to say.
    You paid for 1600 memory and I think that you'd have the best of all worlds if you can or want to run at higher speeds.

    ** edit ** I forgot to suggest that you RMA your current memory directly with Corsair for one of the recommended models they suggested in their forum post.

    Uh oh,
    Corsair may not have anything to replace these with any way. The compatible list for my motherboard is growing shorter.

    Do you think they will send me some 1800's instead? - That would be lovely I think.

    Corsair Drops Elpida Hyper ICs in Dominator GT Line - Legit Reviews

    We have seen a number of reports across various forums about failures of modules (from Corsair as well as from other memory manufacturers) built with Elpida “Hyper” RAMs. Through lab testing, we have now been able to reproduce similar failures. We are continuing to test to determine the cause of these failures. Note that although a relatively small percentage of “Hyper” ICs appear to be affected, the rate of failure is not acceptable to Corsair or to our customers. Due to these failures, we will no longer sell Hyper-based modules until the issue can be resolved. We have also have asked our retailers to return any modules they currently have on their shelves. Products impacted include TW3X4G1600C6GTF, TR3X6G1866C7GTF, TR3X6G2000C8GTF, TR3X3G2000C7GTF, and TR3X6G2000C7GTF. We are working on enhancing our manufacturing and testing process to be able to offer these parts again as soon as possible. We continue to stand behind these modules 100% with our standard warranty, which can be found at Welcome to Corsair :: Warranty.

    Sounds to me like you now have time to play with your current memory and see how far you can go with it. In the meantime, I'd start the RMA process & see what options they will offer. I've seen several other posts where the manufacturer couldn't offer a similar replacement component and upgraded the owner with somewhat better replacements at no additional charge.

    You might want to change the thread title to "As The World Turns".

    With my luck, Corsair will go chapter 11, or worse; chapter 7.
    All these ram recalls have got to be costing them a fortune. It's happening to their 4GB and newer 1.6v 6GB kits.

    I have tried going past 1400 (1407)@ 3.20B with same or higher MCH core, same or higher Vdimm keeping the CPU under 3.66 GHZ - and no go.



    Edit to add - it's not just Corsair having these problems - it's all the ram companies using the Elpida Hyper ICs
