Capacity
4GB (2GB x2)


i can get them cheap from a friend, for the memory list they are PSC

Cheers !

^Just have to test them, could be win or fail, probably more of the latter.

gskill is one of the manufacturers who actually do not let many suprises on low-end binns,like 1600 7-8-7.That being said,chanches of getting one decent set with the specs for benching is rather low,i suggest you look for something else.

[andressergio]

Thanks guys ! very limited here with choices and they're asking astronomic prices for PSC now...

[andressergio]

and this ones ?

ECO GSkill 1600 7-8-7-24 1,35V ?

[websmile]

1040, early PSC Batch, must be X-PSC. The specs are not bad, 7-8-7 at 1,35v is not too bad a bin for PSC. But if these scale with voltage only tests will show, as well as if these do 1200/1300 which you need and want with hard subs at 7-11-7/8-12-8. Ecos are not known to be best of brand at psc, but some early kits did good job at OC. Without pretests, risky purchase

I had a 7-8-7 Eco 1.35V on i5 750 and P55 were 7-9-7 1100MHz with 1.65/1.68v

at the time was what I tested, do not know if the current IB / Haswell would do more.
nevertheless very good in height.

Thanks friend ! but better than those Ripjaws for sure right ?

[andressergio]

damn so many 2x2 started appearing what the heck are this seems hypers...but 2V ???

[mikecdm]

That 2v stuff is probably micron. That first ripjaw kit that you posted, I'd be certain that they're psc. You said you can get from a friend, so you can always check. I have a kit and they're elpida.

Just tested the 2x2 1600 7.8.7.24 eco they only SPI1M at 5GHz 2450 8.12.8.28 2T @ 1.95 vdimm

Still i dont know how to make them more stable

Try to work with the boards profiles - good psc should do at least 1200 tight psc profile, on Z77 this is 7-11-7-28 with hard subs. These are no ideal bench settings with profile because of twcl setting (is at least on z77 asus twcl8) but shows you potential of the mems. Maybe someone using Haswell can give you more detailed advice, but this is first step to see if these are good, mediocre or bad psc

the thing my friend is that i dont really know if those are PSC...im tweaking now and they go boot same speed with 1.75vdimm but still they pass 13 loops of SPI32, either way before only 1M

thanks mate

Hi,try with all low volts on your imc.ioa,iod,

[andressergio]

Hi,try with all low volts on your imc.ioa,iod,

thanks bullant im on stock AUTO volts for that, are those PSC i hate to take the HS off :/

[bullant]

Hi,I never run auto volts on any of my PSC,ivy and haswell,I always set volts my self, on haswell my auto volts are way to high.Just on ic the code 640 I thought they may be BBSE,Sam would be a good one to answer this

Edit,on the volts thing,imc,ioa,iod this is how important it is,lets say im running 2700Mhz 6-10-6 @ 2.1v auto imc,ioa,iod and it is failing at first loop on 32M,the correct imc,ioa,iod volts can make that pass 32m.
Ivy is the same as well in my testing

Known PSC based memory

G.Skill:

G.Skill Pi
G.Skill Flares
G.Skill Ripjaws (Red & Blue heatspreaders)
PC3-12800 ECO 8-8-8-24 (sometimes Elpedia?)
PC3-19200 PIS 9-11-9-28 F3-19200CL9D-4GBPIS
PC3-20000 Trident 9-11-9-28 F3-20000CL9D-4GBTDS

mines are 7-8-7-24 so maybe not PSC but they do go pretty high, can BBSE go that high also ?

[bullant]

The eco g skill may be PSC(1040) and ripjaws BBSe(640) but im not that sure just going on codes,the BBSE are as good as PSC as to what I have see and can run much tighter tRAS,Im sure Sam can confirm these ics

i dont know who is Sam but maybe they dont go so good as theyre binned low speed, for ex Gskills PCS 2000CL6 or 2200CL7 are way better but i dont have them

[bullant]

Sam is TaPaKaH,this may help you too http://ramlist.i4memory.com/ddr3/
Yeah the 2000Mhz + sticks are good,Gskill Patriot and so on,seems your eco can be PSC and BBse and the ripjaws PSC or elpida

Yeas the 2000Mhz + sticks are good,Gskill Patriot and so on

wow thats an amazing list thanks for sharing...i see there they can be BBSE or PCS

[bullant]

No problem http://ramlist.i4memory.com/
