[Team.AU]2GB DDR3 1800MHz Corsair Dominators TORTURED > beware high/tight frequencies

[dinos22]

Hey Guys

I've tested many Intel boards and i felt that none of them gave these 2GB DDR3 1800MHz Corsair Dominators proper justice(nvidia 790i clocks them waaaay too easy to these clocks and timings even at 1.9v but i need to challenge myself here hehe). 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 :shocked::D

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


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 (http://www.xtremesystems.org/forums/showthread.php?t=167233)......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

Very good sticks! My next sticks!! haha

Regards from Spain

[saaya]

nice! did 2t gain you anything?
2.24 is a bit high, was that real or bios?
why didnt you test on 790? :confused: you seem to really <3 790 and you have a great board :D

[M.Beier]

Very sad to see Corsair being technical noobies.... 1800Mhz?? It truely breaks my heart that they obviously dont know a jackazz about their own products....

However write to read and write to precharge are quite tight.

[Solarfall]

those sticks seem pretty nice dinos !!!! ...will be interesting to see if my cellshock ddr3 (also 1800mhz at stock) can do compared to these :D

not sure what you mean?

[M.Beier]

not sure what you mean?

Thats deff not DDR3-3600 sticks :rofl:

And the others were timings I think is tight :)
Trfc seems good for JNL btw, but for DDR3 in generel, quite high... 43-46 is easy with right chips... :yepp:

[dinos22]

hehe mate

other manufacturers are using the same terminology

have a look at this OCZ flagship kit
http://www.ocztechnology.com/products/memory/ocz_ddr3_pc3_16000_flex_ii_edition

also i have crucial 2GHz CAS9 JNL kit here and Crucial also write 2000MHz on their modules
how many kits of DDR3 have you actually tested and what brands?

actually i don't really care what they call them.........they work and OC great, that's what matters to me heh

both this kit and crucials cannot handle lower tRFC and while i've seen some which were lower it certainly isn't high or bad............this will not really affect performance much but it will stability.

Have a look at 3oh6's 15K everest thread and see what tRFC he is running matey ;)

[M.Beier]

That more ppl write it doesnt make it more right :)
Neither is 1600FSB what the QX9770 runs, its still 400FSB.... Even if ASUS and others write 1600FSB on their mobo's, its still BS... Same goes for ram, and as a HW maniac, it hurts EVERY single time...
How many kits I've tested, 5, 6. is to arrive soon, why? As for DDR3, only one brand... I want full detail on products, I select what I like :) (Ram's like fine wine, like women, you dont settle with anything! :p: )

As for Jody, he runs his ram very different then I do... ;)
I havent got a 790i, so that might be the reason... My results on P35 and X38 are very different... Soon X48 is to be tested.... But, honestly, its initial rounds, we all know this... The real deal for the ram will be when nehalem comes... =)

Btw.. Sending you a PM :)

[Broly]

My sticks can't run cas7, but can run 8-7-7-20, which isn't bad for 4gb density

[dinos22]

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

How do you like the E7300?

[M.Beier]

good 2 see some tight timings :)

[dinos22]

How do you like the E7300?

it's a nice chip
it's my testing buddy :D
FSB is pissing me off on it
this Gigabyte is by far the best FSB OCer and i have also tried my P5B DLX which can do 600+ on air with wolfdales with max 480 FSB >> Same for my Asus P5E3 DLX X38 board
