G.Skill ECO PC3-12800 7-8-7 1.35v in the house!

[K404]

JUST got these. My thanks to G.Skill for hooking me up!

Full review to come and better pictures in the morning.














If anyone @ MSI is reading this.... pleeeaaassseeee sort out a low vDIMM BIOS for the GD-80 ASAP!



1.35vDIMM Mobo support:

Asus:
DFI:
eVGA: Supported in existing BIOS. Plans to improve XMP support in upcoming revisions
Gigabyte: Support 1.3 or 1.4 V officially, But if the module has SPD with low voltage then the MB should load the SPD to low voltage as required.
MSI: Supports down to 0.90vDIMM but options below 1.545v are widely spaced and tuning will be a problem. Some voltage steps of 0.08v.

Mobo company reps reading this.... chime in please!

There is a thread about the RAM here and the model is "ECO" not "EVO"

[K404]

typo corrected.

Company-supplied RAM gets a separate thread as a courtesy for their support if nothing else. If you dont like it, tough. How many 5970 OC threads are there in the 3D and news sections? How many Ripjaw threads in the bandwidth section?

Lovely memories

Hope to found time to test them soon

Waiting for results man, Thanks for sharing

[NaMcO]

If you dont like it, tough.

I don't have to like it or not, it's not my business, just warned you as it might have slipped, apparently it's not the case, my bad

[clon22]

Take it easy Kenny.
Awaiting for your results too!
While waiting for 1.35vdimm bios to be sorted out,
maybe try testing 1.5~1.6v to see how they fare?

PICS OF THE RAM

ok ok, so nice pics, meow we want NUMBERS boy!! lol

Results @ 170-180BCLK

Last nights results:

CONTROL CENTRE VALUES ARE NOT ACCURATE!!!!!

850MHz 7-8-7-20 1T. 1.33vTT, 1.55v



875MHz 7-8-7-20 1T. 1.33vTT, 1.60v



900MHz 7-8-7-20 1T. 1.33vTT, 1.65v




0.3vDIMM increase for 100MHz? Its possible that the MSI board, by not offering low vDIMM, is missing the sweet spot for these sticks and these results are being done by brute force of vDIMM. Either that, or they are binned so tightly to SPD that they need lots of juice to scale.

More to come. Again...short on time before I leave for work

[proxis]

they definitely don't overclock the way everyone expected before launch most likely to poor scaling
so, i see no point in these .. you can get a cheaper 1.65 kit which will perform same at 1.35-1.50, if not better

[K404]

If these keep scaling, i'd expect to hit 1000MHz 7-8-7 at 1.85vDIMM. ~0.07v worse than my Ripjaws.

If there is a problem, I would be inclined to think its the binning point. 800MHz is pretty easy for DDR3 now so 800MHz 7-8-7, 1.35v is maybe not so much of a challenge.

If, in time, G.Skill release a 1.35vDIMM part at 1000MHz, that could be a winner.

That is deffo not my final conclusion!!! I do think theres a market for this, it just might not be extreme OC...

Thats not my final conclusion either!

I want to see these on P55 at lower vDIMM

[K404]

New pics up


I think im going to stop with this RAM until MSI can provide a better-supporting BIOS. I get the nagging feeling im doing something wrong and G.Skill deserve better than an "irrelevant" review because I can only run the kit out-of-warranty

[MadMan007]

lol ECO probably saves a few watts huh? Green branding goes way too far some times. Also I like how it comes in a NON-environmentally friendly plastic packaging :p

(This is nothing against the OP I just saw this thread is all)

[Andrea deluxe]

you can try:

1.5v or 1.65v

1600mhz

6 7 6 18 1t or 6 6 6 18 2t



????????????

[Ozzfest05]

btw its in the hizooose.

[K404]

you can try:

1.5v or 1.65v

1600mhz

6 7 6 18 1t or 6 6 6 18 2t



????????????

800MHz 6-7-6 1T vTT 1.33v, vDIMM 1.54v (lowest I can set)




There ya go SO far, none of my RAM on 1156 will run tRCD @ 18. I might have a look at that in time to come


Thats 0.1v less than my Ripjaws need

Control Centre readings are not accurate. Also.. while it does allow me to reduce the vDIMM in Windows, the resolution is low and the options run from 1.515v, 1.500, 1.425v...

[Andrea deluxe]

ok but you can test

1600mhz 6 7 6 18 1t

1600mhz 6 6 6 18 1t

1600mhz 6 6 6 16 1t

tanks!!

ps: set uncore to 3200mhz..... require low voltage to v-qpi.....

[K404]

There ya go SO far, none of my RAM on 1156 will run tRCD @ 18. I might have a look at that in time to come

I'll try 6-6-6, but I dont expect great MHz with it


3.6GHz Uncore @ 1.33vTT isnt toooo bad. Id rather test options at higher BCLK because thats what overclockers will run I might be able to reduce vTT... I just picked that value. If it can run high BCLK and good RAM at acceptable voltages... the guys interested in undervolting/ low-power use should get a good operating point to reduce the voltages in their own rigs and have some fun

[Smartidiot89]

So to spam another thread, tested on AMD yet?

[Riska]

I will get them in a few days and they are going in A MSi 790FX-GD70 with a P II 965 C3 so i will report back

Some comments from tonights testing so far (Some ECO notes, some I7 RAM clocking notes)


This RAM will realistically only work at stock if used with low BCLK. I COULD NOT get this to run at 160BCLK or 200 without a voltage jack.

Flipside of running low BCLK: I can use lower vDIMM for a MHz/ latency combo. example: 920MHz 7-8-7 1T @ 1.55vDIMM. Series of screenies to come.

Stick order will have an effect on stability, especially when you get close to the edge If you have trouble getting things stable... try swapping the sticks over (using the same slots.) You might already be using the best stick order... but try swapping them, just in case you're not. Its always made a difference for me.

tRCD and tRFC will require voltage to be pulled down. Yes, I know thats an obvious thing to say, but if you want to chase MHz or voltage efficiency, sacrificing one or both of those timings will be worthwhile.

This RAM kicks out no heat at all

I still dont think this RAM has 1GHz in it at worthwhile timings
