    Hey Guys

    I've tested many boards and i felt that none of them gave these 2GB DDR3 1800MHz Corsair Dominators proper justice. WEEEELLL times have changed and so did the arrivals of an RMA replacement board from Asus, namely P5E3 DLX (X38) and newest arrival in my torture dangeon from Gigabyte, namely X48T-DQ6

    Man oh man do these new X38 & X48 boards unleash the power of this RAM :D:D:D:D

    These runs were very fast 32M Superpi indeed :D >> i probably have a couple of seconds in efficiency to tweak out of it for all of them but it gives you an idea anyways :up:

    If these were P35 boards i would probably be able to torture them into giving me PL6 at 500Mhz but for now on air stock cooling i'll back off on MCH volts

    32M SuperPi time: 11m 01.515s
    CPU: Intel E8500 3.16GHz
    CPU Freq: 4000MHz @ 1.27v
    Brand: Corsair Dominators 1800MHz CAS7
    Model: DDR3-1800 7-7-7-20 2.0v
    Size: 2GB Kit ( 2x1GB )
    Voltage Used: 2.30V (max vdimm it likes >> anything more and results worsen)
    Timings: 8-7-6-18 1T (very tight sumbtimings)
    Frequency: 1000MHz ( DDR3-2000 )
    Cooling: Air Cooling, 24C room temp
    Motherboard: Asus P5E3 DLX 0703 bios
    MCH Volts Used: 1.65-1.7v (fan blasting at the heatsink)
    GFX Card: Gigabyte 9800GX2
    PSU: Corsair HX620 (620W PSU)
    Power meter: Powermate attached measuring 210W from the wall during 32M SuperPi run
    Other settings: AI Clock Twister on Moderate; Transaction Booster: 3

    32M SuperPi time: 11m 23.079s
    CPU: Intel E8500 3.16GHz
    CPU Freq: 3850MHz @ 1.27v
    Brand: Corsair Dominators 1800MHz CAS7
    Model: DDR3-1800 7-7-7-20 2.0v
    Size: 2GB Kit ( 2x1GB )
    Voltage Used: 2.30V (max vdimm it likes >> anything more and results worsen)
    Timings: 7-6-6-18 1T (tight sumbtimings)
    Frequency: 960MHz ( DDR3-1920 )
    Cooling: Air Cooling, 24C room temp
    Motherboard: Asus P5E3 DLX 0703 bios
    MCH Volts Used: 1.65-1.7v (fan blasting at the heatsink)
    GFX Card: Gigabyte 9800GX2
    PSU: Corsair HX620 (620W PSU)
    Power meter: Powermate attached measuring 200W from the wall during 32M SuperPi run
    Other settings: AI Clock Twister on Moderate; Transaction Booster: 3 >> due to the fact i was running CAS7 MCH allowed me to run PL-6 on this run (for tight PL you need tight timings and CAS in particular

    970MHz crashed on 8th loop so with some tweaking and vdimm tuning 970MHz 7-6-6-18 1T is within reach :shock: :D

    I've been doing some testing with Gigabyte X48T-DQ6 with some equally impressive results :thumbup:


    32M SuperPi time: 9m 58.437s
    CPU: Intel E8500 3.16GHz
    CPU Freq: 4598MHz @ 1.58v
    Brand: Corsair Dominators 1800MHz CAS7
    Model: DDR3-1800 7-7-7-20 2.0v
    Size: 2GB Kit ( 2x1GB )
    Voltage Used: 2.24V
    Timings: 8-7-6-18 1T (tight sumbtimings)
    Frequency: 968MHz ( DDR3-1936)
    Cooling: Air Cooling, 24C room temp
    Motherboard: Gigabyte X48T-DQ6 F4 bios
    MCH Volts Used: i tried between +0.25 to +0.55v (fan blasting at the heatsink)
    volts didn't seem to do much but results were there regardless :D
    GFX Card: Gigabyte 9800GX2
    PSU: Corsair HX620 (620W PSU)
    Power meter: Powermate attached measuring 240W (i think eek forgot) from the wall during 32M SuperPi run
    Other settings: Memory setting > Extreme

    I could easily benchmark 980MHz but i am showing a screenshot with a sub-10minute mark which i was specifically benchmarking for :D >> i was a hair away from a 4573MHz sub10m run as well

    If you would like so see a lot more of these crazy RAM speeds and extremely efficiency SuperPi run be sure to visit one of XS's oldest and longest running threads called 32m SPi Low Clock Challenge......see what some of the best superpi/system tweakers on this forums are up to and join in,.,.....it's a lot of fun and very challenging (BEWARE > you will kill lots of hardware for that extra second or MHz hahahah)

    thanks for reading

    thanks mate

    time are very fast indeed but they are not the fastest yet so not good enough until i get there :D:D:D:D

    Nice results, are these sticks using the Micron D9GTR's? Any idea of the PCB being used (ie brainpower 8 layer etc)

    Is this the fastest ram you've ever got you hands on?

    yeah these are GTRs
    pretty sure all dominators are 8layer sticks but you should check with Yellowbeard in regards to that

    fastest for sure dude :D
    little birdy tells me there is something faster incoming soon as well EEEK :D

    Very nicely done mate - ace efficiency there :thumbup:

    I saw some stuff today that I think you'd find particularly interesting :leet: stuff like LN2 ready memory (hahah, wtf? useful? blah!) and also the ASUS Rampage Extreme; very very fkn cool board with 16 phase socket power and a few other tasty features. Oh, and the P5Q3 Deluxe sample should be in when I get back too :thumbup: Hopefully it's better than the crappy P5Q Deluxe :Paranoid:

    Looks like we could have a fun session when I get back :D

    Again, top effort mate. Some solid results - congrats.

    woot woot! Sound good!

    Taiwan's been nuts and so was the one night in Singapore - I got to catch up with T_M :D

    Have a look at this:

    [​IMG]

    I don't think it'd have too great an effect and would be a pain to insulate but hey, why the heck not give it a try :D

    Also there's some new sticks coming shortly from Patriot and OCZ - it should be interesting.

    oh man oh man
    i would kill for that pot

    damn it josh you better sweet talk me a pot out there biatch
    i have some plans with my dominators/dice and 3v and 700MH CAS4 benches heheheheheh :D

    Just got back from the pub... interesting :Paranoid: BTW, fudzilla says hi hahah

    I'll drop in and see if I can get something but I've got a few special pieces coming from other peeps. What we really need to worry about it Charles with his E0 stepping quads.

    He was benching 3DMark06 @ 6.07GHz under LN2 and on a shitty 4-phase Abit X38 motherboard - there's trouble brewing there mate.

    Amusingly, his X4 9750 that he was meant to be overclocking for AMD cold bugged at +12'C :p

    Argh, I need sleeeeeeeep.

    Ciao.

    this gigabyte board is really something else

    i could not run these sorts of frequencies and timings on any of my RAM in the past

    i even managed some decent speeds/timings with two different RAM kits installed in there eek
