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

[jalyst]

Cheers mate, but once they're off, they're not going stick back on as firmly are they?

[PiLsY]

Mine seem to be back on just fine . Just dont touch the tape and go slow, but yeah if youre at all nervous about it dont bother. It definitely wont make them overclock any better .

[Punisher!]

Noticed a strange problem on AMD with 4x2gb G.Skill ECO.

They perform really well:


But the suffer of cold boot problem. No matter which setting... with cold PC they fail Prime @any setting. They need some stress before getting stable and then they perform like in the screenshot.

So I managed to get to 1866MHz using 6-9-7-22 1T timings stable on prime 95 and ibt. These things rock!

So did you end-up checking that you definitely have PSC?

[Bei Fei]

I just started testing the ECO kit so far I have 2133 8-10-8-28 1T @ 1.5V. I am going to do more testing tonight and hopefully I can push these babies to Cl7 2133.

^ Do you know what IC's you have? PSC, BBSE etc.

PSC 100%

Yeah I got PSC's ic's...damn the trcd!!! lol

[PiLsY]

Nice sticks there Bei, could have a chance at cl7 2133mhz given the voltage you have to spare. These Eco's are truly epic on Sandybridge, its always great to find an old dog that can do new tricks.

Good job on the CL6 too Boe, nicely tweaked there man .

Yes indeed, makes me wish I was on SB!
I personally will have to wait till Ivy Bridge
I may do a VMM/NAS build before then though

[PiLsY]

Unfortunately my BBSE and PSC pairs wont play nice together - severely limited the oc on P55. After the poor experience with the BBSE pair on P67 I must say I havent bothered to try 8gb yet. The Asus is packed up and ready to go back anyway after the chassis fan channels failed (in addition to it not posting with the patriot hyper sticks and not working with Asus's own Xonar D2 pci soundcard), so I'm back to the P55 for the time being.

[jalyst]

^ sorry to hear that mate, hope you have better luck with the next MB!

[PiLsY]

I tested the Asus one last time before taking it back and the damn thing worked . Mustve been the 2 weeks powered off with battery out.

Been playing again and now have 8-10-8-27-1T stable @ 2150mhz. I need 1.65v for it though.

Bei what are your subtimings all at on that Asrock? I assume its got pretty much the same ram timings as the Asus? I dont think I can gain anything from slackening them off as Im currently tightening them up (without changing voltage). I cant run Tras below 27, havent tried it at 30 and going for more mhz yet though.

Here's my G.Skill ECO 1600 CL7. The marking shows that it's likely to be Elpida BDBG. However, the chips are screened with E202Axxxx (can't remember the exact numbers)

Tested with Asus P8P67 Pro-B3 and 2600K.

DRAM voltage is set at 1.6125 to achieve stability.


And 1.65v DRAM voltage(didn't try lowering it). Need more testing tho.




Update chip pics

Nice .

Memtest stable is never prime blend stable though so be prepared to drop mhz or up volts once you start testing in windows.

Have you tweaked 2nd and 3rd timings or just using Auto?

Yes, will do more testing with Prime95 later.

What do you mean by 2nd and 3rd timing? If you mean tRCD and tRP then this is the best this kit can do. Anything lower causes boot failure or freezing in BIOS.

[PiLsY]

In the memory timings section in bios asus have the timings split up into 1st, 2nd and 3rd "groups". Auto sets these VERY relaxed and you can tighten up at least the 2nd set quite a lot. Mine are PSC though so could be different to yours...

[reisya]

is it elpida ? i set vdimm @1,59v
i can't open the cover coz make warranty void. lol

Yes, you can take 1 side of the heat spreader off. The adhesive is not that strong but you need to do it gently

You're making me regret that I sold you the kit!

Glad to see it can be pushed so hard. I wonder what I was doing wrong with it. Maybe that itx board just sucked at clock ram?

[PiLsY]

P67 is the key dude. Its a clear +150mhz with these PSC eco kits compared to earlier chipsets.

[Bei Fei]

I lied on my sticks.....

I undressed them and they are 100% BBSE

[NEOAethyr]

I think these are gonna be my next purchase.
They're cheap and clock well .

[danielkza]

My kit won't do anything below 2133 9-10-9-28 on a P8P67 PRO, even with 1.65V. I'm tempted to take the heatsink of and found out what I got, but it's on my main rig and I'm too afraid to rip the ICs of

EDIT: Scratch that, just flashed in BIOS 1704 and apparently 2133 7-10-7-28-2T is good for 20min of blend so far, which always failed before 2 min on all previous BIOSes. I guess my kit is not so bad after all.
