    G.SKILL F3-17000CL9D-8GBXLD

    Test platform :
    Intel i7 3770k
    Gigabyte UD5H Z77
    G.SKILL F3-17000CL9D-8GBXLD
    Windows 7 SP0

    Benchmarks :
    Super pi Mod 1.5
    MaxxMem
    AIDA 64 memory and cache benchmark

    Thoughts :
    I found these memory sticks were performing great up until 2300mhz, after this point it became neccesarry to loosen the timings and add more vdimm and vtt to gain stability, once I started into the 2400+MHz range the memory was becoming more and more unstable and timings nor voltage seemed to help here, this may not be a limitation of the memory here and may very well an IMC limitation of my CPU.

    For a very reasonably priced 8GB kit of memory this is a great kit, while it is no 2600+mhz monster kit it would definatly suit most enthusiasts who could very easily sit at 2300MHz @ 9-11-9-30-2T without the need to bump any voltages. While I did manage to hit 2500MHz on this kit it was not stable enough to pass even 4m SPI, but would happily pass Maxxmem and AIDA 64.

    The Gigabyte UD5H was an extremly solid board, I honestly could not fault it in any area, wait yes i can no PS2 connector !!!!!!

    Not bad at all, will you be getting access to the 2600mhz kits about to be released from G-skill?

    I doubt it as the 2600+mhz kits are very hard to bin for and the run they get is very quickly sold and very hard to get a sample of.

    I do hope so but only time will tell.

    I'm going to take a guess and say samsung.

    Very nice clocking Fester. GL finding an even better set of ram :).

    Love how you managed to find a flaw in the UD5H.

    Solid results Fester, ram looks good for it's price range.

    Can't wait for Ivy. :D

    Normally a solid guess but Samsung IC's normally have the letter K in front.

    Elpida has ED, Hynix has HY, Micron has an MT; an IC without a letter is interesting given the the first one or two letters normally denote the manufacturer.

    Nice job Uncle, thanks for posting.

    Are these a commonly available ram that is seeing new overclocks thanks to Z77 ram divider and Ivy's mem controller? If so does that mean there may well be lots of rams that soar to new heights on the new platform?

    Any chance you could try some G.skill 2133-8-9-8 rams and see how they go? Or some hypers in a similar style review?

    Hi, I'm running the same set currently it in my Asus P8Z68-V Pro(Gen3) ..
    I also own some other similar models, P8P67 Evo(Rev 3,B3 Chipset), 2x P8P67 Deluxe(Rev 3,B3 Chipset)

    My question is what do these equal on the Asus mobos:

    CPU VTT 1.100v IMC 1.100v

    I am pretty sure CPU VTT = VCCIO

    My set running in my P8Z68-V Pro(Gen3) have required a similar vccio voltage.
    And my slower timing set at 2133mhz have required the same 1.1 vccio voltage for stability too(random bsod gone!)

    So yeah im just making sure i had set the right thing from the start , yeah?

    Thanks Alan.

    Hi Alan, with the new z77 platforms they have split VTT and IMC voltage, on p67 and z68 these were linked and called VCCIO, now you can adjust them separately, there is debate amongst users that IMC voltage does nothing and the only voltage that is helping memory clocking is the VTT voltage, however on the board I tested I noticed the VTT voltage was not applying unless the IMC voltage was within .04v of VTT.

    I hope this explains it a bit better for you.
    Jon.

    edit: also please note 1.100v IMC and 1.100v VTT is the default voltages.

    Have you tested any 2400+ rams on Ivy yet?

    Not yet as still waiting on new bin, I am well aware of the 2666 mhz kits from gskill are happily benching at 2800mhz on air, these are very high bin and will have a price tag to match their awesomeness.

    Yeah too dear for me, I was thinking more along the lines of the well priced Team 8GB kits, c9 2400 mostly. Edit: these

    PSC / Hypers (If you have any left) plus some liquid nitrogen could probably do 2800mhz easy. What do PSC use for there powerchip ram codes?

    Thinking from memory CMGTX1s were PSC and rated 2400 9-11-9-2T (they were sposed to be cherry picked sets however they were also rated for X58 and Ivy will no doubt be driving memory harder then X58). I'm starting to lean towards PSC for the identity of our mystery chips.

    Now to find pictures of ghetto ram pots :)

    In saying that Hynix H9Cs seem to love mhz so maybe time to bin a set or two of those? Their main timings are pretty loose but there sub timing can go pretty tight relative to there speed. Maybe Ivy will prove that Hynix H9Cs were ahead of there time when they were released...... Time for a bold prediction. Ivy bridge will see the rise of hynix H9C as the top sets of ram for OCing

    Do you really think 2133 PSC rams will go that fast? What about on air?

    No they won't unfortunately, tested already, PSC are great subzero for around 2600mhz with 7-9-7 timings but they won't hit 2800 and hypers are pretty well the same boat but don't clock as high.

    Hi, oh ok, yep understood.

    Thanks for the reply, didnt expect it at midnight.

    I am up because i dont feel like sleeping much. i had to put one of my dogs(rayden; Rip) to sleep today, bone cancer-he wasnt good. I will miss him. Tomo we have to organize his cremation too, soo sad..what a day.

    So i am playing with hardware, keeps my mind amuzed.

    Cheers Alan.
