Ok, so what is with these? Since they are low voltage, does that mean they will run @ 2000mhz with 1.6-1.75v?

[Hondacity]

no results yet...just setting up the tone :D

as for 2000mhz... for specs it can do 1866 @ 1.35v

@ 1.5v (dataseeht) i'm betting it can do 2000mhz

[Patch]

So how do these new low voltage series of RAM do with 1.8v+? (Not necessarily these in particular, but low volt ram as a general class).

Sometimes need high vdimm to help cold bug.

we shall see i don't mind burning 100$ LOL

Me either... you should send it to me so I can burn it for you ;)

Hey HC, do you know what the difference is in the Elpida Base and Epida Hyper is?

Are the Hypers stronger, or is there no real difference?

[Hondacity]

all the elpidas are edj1108 series

first ones were edj1108BASE m(NH)-e ...remember the failures...these were them
then came m(GH)-e

A - means A die revision (70nm)

then cam edj1108BDxx

D - die revision to 50nm....

but anyways class/speed classifications:

GH - highest
GN/GL just under GH.....this is rated 1600mhz @ 1.5v
DJ - example sf3d's kingston 2133C9(1.65v) ** the chips are rated based on 1.5v DJ is 1333mhz
AE - slowest

that's like the first thing i saw too!:ohcrap:

1.35v :eek:

[Hondacity]

oos now

oh well...time for another search

[Cecil]

Arent these the same as the Gskill Ecos?

[Hondacity]

the gskill ecos are ...i'm guessing are elpida bbse they don't scale well with higher voltage..

The reviews Ive seen and the ones I have do.

[Hondacity]

not sure what vdimm range you are talking about. but what i'm talking about is over 1.7v that yields good results because of overvolting.

Anyways, I am getting off track here. At the rated latency of 7-8-7-24 and 1.35 V the G.Skill 1600 MHz ECO kit actually has a healthy amount of headroom. I ended up with 1715 MHz at this "stock setting", which is a very good overclock. Pushing the voltage to 1.5 V, I managed to do a successful run at 1800 MHz, but increasing the voltage beyond that did not yield any improvements once again.

We have seen some other tests of the same kit scale up to 1.65v but ours topped out at 1.58v max so we decided on a max of 1.55v for our testing.

Oh, I was talking up to 1.65v or so. Have seen 2100+ 6-9-6 or 6-10-6, I forget which. It was at XS.
With 1.45 I can do 7-8-7 1800Mhz prime stable, or bench around 6-7-6.

Just sucks that was with AM3, and now on my i5 Im stuck at stock with them from the mem controller on this i5.

[Hondacity]

am3 can't do high frequency yet...the imc just doesn't have the speed with higher memory...

2100 @ 6-9-6 sounds more like early psc... the elpidas can't do super low tCl @ high frequency... even if tRCd is delayed/softened

I was getting far higher mem speeds on AM3 then I am on this setup now though. 1800 was a breeze with the 965 I had, and I cant post past 1600 with this i5.

Ive seen some AM3s up to 2300. Not as high as Ive seen 1156, but still pretty high.

[Hondacity]

i just read the thread over @ xs

http://www.xtremesystems.org/forums/showthread.php?t=239426&page=5

- limited max voltage
- possibly bbse because of limited voltage
- also possible psc of old revision...

anyways its a different chip they're using from the kingston lovos.

Sucks that.. P55 loves the QPI...

Gotta do high qpi/mem on p55 to equivilate that X58 stuff :) THought that was the benefit of going with a budget chipset.

HC: Thought that thuban could break the 2K barrier?

[Hondacity]

its not p55

its lynfield imc versus clarkdale imc...

i remember ceil had a i5-7xx ...i forget

Umm are you talking to me? I am confused. Not sure what you are arguing about.

Do you disagree that p55 chips need more QPI and memspeed to = X58 setups? Or are you just arguing my terminology? (I think that is it.. since you said its not p55... its p55 chips...)
Just curious

[Cecil]

He is saying P55 isnt limited to low mem speeds, its Lynnfield CPUs. I have an i5-750, not a clarkdale, which is why I cant get over 1600.

I knew it wasnt going to be really high, just dissapointed I couldnt get at least get 1800 out of it.

you're right about the p55. but a little correction..

clarks are limited..not lynfield( 7xx or 8xx)

**most of the highspeed ddr3 rams are tested with lynfield cpus...

*** the top scores for the hwbot competiton august 4ghz will be on a lynfield because of the imc...

I thought Clarkdales were better, I must just have a really shitty lynnfield then.

I still have time to take it back to Microcenter and get a 760 for $10 more, think its worth it?

[Hondacity]

what was your blck? memory subtimings as well?

What bench are you after?

[Cecil]

None, its my daily gamer. Ill probably try for a good pcmark05 though.

The 750 I have it really good with low volts for stability, but runs kind of hot and has a shitty mem controller. With x8 mem I cant post too much over 200BCLK, think maybe 202, I forget. Raising volts and timings didnt help. Going down to the x6 multi is fine though.
I cant even get 1600Mhz 7-7-7 instead of 7-8-7, though the ram is more then capable.

[Hondacity]

i can't say if a new 760 would help...

i'm still wondering what your vtt and pcie is... also what is your mobo?

Gig P55A-UD4P. 200x20 24/7 stable 1.29vcore and vtt. Tried up to 1.35vcore and vtt as well as 105 PCIe for 205x20 x8 mem, and 170x19 with x10 mem multi. All results in no post. Just cycles then comes up with the overclocking failed thing. 205x20 and 195x21 are fully stable with 1.32vcore and 1.31 vtt, default pcie when ram speed is less then 1600Mhz.
