bummer, did you buy yours recently or many months ago?
pretty recent (a few weeks)
*edit*
4GB of it purchased on 10th March, 4Gb on 31st March.
I don't know if each set uses use the same chips (haven't compared them so far either)
If I can find a small enough razer blade, I might try taking the heatspreaders off to see what chips are underneath.
Think I was about 24/2 and 3/3; so about 8 and 7 weeks ago.
That'd be sweet if you could, I'd do the same but I'm not game! :)
Plus I'm not about to start my build for some time yet.
Still researching some final parts.....
btw about elpida chips. mine use elpida chip, but cant run CL6 @800Mhz :mad:Quote:

yeah, 1.67V is kinda high to keep them stable.
yuph. at 1,67v make my eco stable..Quote:

Thanks for the reviews on these.
The question I have that I didn't see addressed anywhere is will these sticks do their rated spec on 6:1 strap stable at stock 1.1v uncore voltage with everything else at default?
Yeah, I know this isn't exactly an "Xtreme" question but I'd still like to know the answer if you guys happened to notice when you were benching them :)
I noticed the Kingston pair I'm currently using jack up the uncore to 1.3v to achieve their rated speed when applying xmp.
This is in spec for Bloomfield but is well above Intels published max of 1.21v for Lynnfield.
(btw, there is zero mention of this little fact on the packaging or on their website and there doesn't seem to be any way to get this information until you actually plug them in and review the bios settings.)
Bloomfield sticks, imho, are just not designed properly for Lynnfield.
Glad to see the ram manufacturers starting to address this.
I've asked Mushkin to swap my DOA 996782 RMA sticks for their 1.35v 996825s (I offered to pay the difference) for this reason but I don't know yet whether they will come through.
I'd like to test these further to see how high I can clock them. Though I don't exactly have the best board to do that with right now.
My board's better than your avg h55/h57 and even most p55's for OC
http://www.anandtech.com/show/2929/5
One of these days when I actually get round to building my htpc/pvr I'll try a bit of OC'in.
But I'm not interested in hardcore OC's, and one shouldn't expect them with these sticks.
They're not record breaking sticks, but they're pretty good for what they cost.
I'm thinking of getting a Crosshair IV Formula or Extreme board. From what I've seen they can get the most out of RAM/HTT.
Oh yeah they're pretty damn good, & i especially love the frequency/timings they hit at such low stock voltage.
Some of the top-end p55's or x58's will be slightly better than my mobo for hardcore oc's, but that's not the emphasis for my build.
I took the heatspreader off one side of one of my RAM sticks, and this is what was under it:

It reads: XDX028A3G-A

I have that kit running on my P8P67 Pro at 7-10-8-24 1T @ 2133MHz so its pretty decent stuff so far.
the eco stuff is amazing, not sure if anyone else has made anything quite like it yet.
yeaa

Wow! Subtimings at auto in bios? I haven't tested my eco's on sandybridge yet - ive got an early BBSE (bought on release) and a later PSC set (4 months older). They were good but not great on P55...
P8P67 Pro loves these sticks. Full auto timings in bios at 2133mhz gives 10-10-10-30-1T and its only taking 1.54v for prime blend. Also gained some bclk (still climbing) over hypers - previously 104.2 max using 1600mhz, currently testing 105.2 @ 2133mhz. These were nowhere near this good on P55/X58. Will tweak timings once I find the mhz limit, but already above 25k read in aida @ 2250mhz 1.6250v. Astonished :up:.
Amazing to hear they just get better on latest Intel chipsets/MB's, thanks for sharing!
You make me want to get a new MB, damn you! :)
2237mhz 1.60v/1.15v 9-10-9-30-1T with everything else at auto is 4 hours of blend 3200mb stable. 8-10-8 is taking more volts but could be possible, testing at 1.65v/1.175v now. The sticks are also now scaling past 1.58v unlike on P55/X58. I've still only adjusted primary timings, subs will be able to be tightened quite a bit to bring up bandwidth - will post aida when tweaked. For now its just over 25.2k read when prime stable at 2237mhz and will run aida at up to 2262mhz same timings and volts. Suicide stability bandwidth should be good :up:.
Bclk topped out at 105.2 stable and 106.1 boot. That's up 1mhz stable and almost 2mhz boot over my hyper sticks(104.2 stable/104.3 no post). So much for it being all down to cpu!
[Edit : 8-10-8 no go, 9-10-8 fine, struggling with 9-10-7 but its close. Looking forward to trying 6-8-6 @ 1866 tomorrow now ;)]
M4A89TD and M4A89GTD also clock high ram.Quote:

Well I couldnt stabilise TRP 7 or 8 in the end at 2237mhz, got 20 mins of blend with 7 and about 2 hours with 8. 0x1a Memory Management bsod which doesnt seem to go away even if vccio, vccsa and vddr are raised. Used to be QPI/VTT on p55/x58, may be subtimings on P67. Will investigate later, just looking for rough targets at the moment.
Tried 6-8-6 @ 1866mhz 1.6v - various BSOD's booting. 6-9-6 has been priming 10 mins now, looks like its got some headroom in it.
TRCD 9 is a no go at 2133 for blend stability. Will do various benches up to 2200 though. At a guess 9-10-8 should be stable around 2200 and 9-10-7 around 2150.
These sticks are fast for the timings too - higher bandwidth than hypers by about 1.5k read at the same timings.
Teh awesome keep probing, I'd love to see the limits of these sticks! :up:
They're already doing very well, considering they're not really geared for massive OC's.
They wouldnt do 1600mhz 6-7-6 blend stable, only 1575mhz. Any higher than that and its a memory management bsod in prime. 6-8-6 went to 1685mhz no problem then im bclk limited, so for sandybridge and eco's at least that timing set is a little pointless.
9-10-9 at high mhz is going to be the fastest overall timing set, its a clear 2k mb/s read ahead of everything else.
Got 6-9-6-24-1T up to 1925mhz for 23.5k mb/s read in aida.
So, to sum up blend 4 hour stability:
6-7-6-24-1T approx 1575mhz
6-9-6-24-1T approx 1925mhz
7-9-7-24-1T approx 2050mhz
7-10-7-24-1T approx 2070mhz
8-9-8-24-1T approx 2080mhz
8-10-8-24-1T approx 2100mhz
9-10-9-27-1T 2233mhz+
And voltage point testing:
9-10-9-27-1T 2237mhz @ 1.62v
9-10-9-27-1T 2188mhz @ 1.58v
10-10-10-30-1T 2237mhz @ 1.56v
10-10-10-30-1T 2133mhz @ 1.5v
10-11-10-30-1T 2133mhz @ 1.42v
11-11-11-30-1T 2133mhz @ 1.38v
11-12-11-36-1T 2133mhz @ 1.35v
Now I dont know if this is my PSC or BBSE kit. Going to test the other against the results from this one tomorrow (need a break now!).
thanks for sharing that mate.
thx pilsy for results here is mine
7-10-7-27 1T 2133MHz 1.64V
http://www.pohrani.com/?2r/wc/3x7HLv...27-1t-164v.jpg
Nice timings pilsy! Hopefully I can improve mine Eco's performance like that.
Just discovered that the mem slots on the P8P67 Pro react differently to timings. Pair A (closest to cpu) are more stable at lower mhz / lower timings and pair B give you more stable mhz with higher latency. Switched over to pair A and Ive got 6-7-6-24-1T stable at 1612mhz 1.63v. Below TRCD 8 you want the Pair A, above TRCD 8 you want Pair B. At TRCD 8 its all the same. Worth bearing in mind if you try to run 4 x 2gb on this board.
6-7-6-24-1T 1.62v 2 hr prime stable and 22.9k (same subtimings as 2237mhz top run, no tweaking yet) in aida64.
Sandybridge definitely prefers that 21.33x multiplier. I'd guess its linked to whatever passes for uncore speed these days and thats where the extra bandwidth is coming from.
Enjoying playing about with this stuff and discovering new ground. Farmer Boe you look to have better sticks than me as you can do cas 7 2133mhz - hopefully you can get some good results from yours :).
Well I found mine are not prime stable at cas 7 for more than half an hour...it was just a quick tune for the cas 7 at first. Now i'm going to try get the 6-7-6-24 at 1600-1700mhz settings like you did on your kit.
Yeah I've noticed its back to the days of using Prime Blend for ultimate stability even though Linx gives me much higher temps I can run all mem Linx for 50 loops a good 50mhz cpu and 30mhz memory clock higher than I can do a 4 hour blend at.
Let me know if you can confirm my findings with the ram slots or if I just have something weird going on! :)
2237mhz 9-10-9-1T @ 1.62v turned out to be unstable - memory management BSOD late last night. I think that last couple of mhz is just a bridge too far, backed it down to 2233mhz at 1.60v and its been priming now for 12 hours. Finding slots 1 and 3 worked better at low latencys than 2 and 4 put me back a few hours yesterday, so going to tweak subtimings now and see if that leads me anywhere. After that i'll swap the other sticks in and see if they go further on the same profiles, then its a heatspreader lift as I cant remember which set of sticks are PSC and which are BBSE - lol.
Well last night I got my sticks to 6-8-6-21 1T @ 1696MHz prime and ibt stable. I think mine have PSC ic's as I cannot get them down to 6-7-6-X on any setting besides dropping them to 1333MHz, and who wants to do that? I have the black heatspreaders but I'm not sure if it confirms the ic's either way. I'm going to try for CL8 stability at 2133MHz tonight and see how it goes and perhaps I'll try swapping slots in my P8P67 Pro to see if that helps my tune.
See what 6-9-6 will do for you man. Remember you can drop bclk below 100 so you could run say 21.33x94 bclk for around 2000mhz.
I still seem to be struggling with the odd thread drop in prime. Coupled with the memory management bsod I wonder if I have subtimings off somewhere. No idea where to start though coming from a gigabyte background as not much has the same name.
anyone tried doing 12gb of this stuff?
i have 6 sticks of this that i originally had before going to my Dominators. i even upgraded their cooling with Xigmatek heat spreaders, of which i modifidied... well more or less stripped the thin metal sideways fins off because they weren't made for down-wards air cooling, but side to side cooling. so now that have a bunch of towering alluminum points. works like a charm though.
EDIT: damn, had a look. both my dominators and my ecos have PSC chips. YAY for tRCD nightmares!
Spreaders lifted, they were the PSC sticks. Release day BBSE sticks going in now.
These have a chance at 8-9-8 2133mhz - they do 2080mhz 8-9-8 1.58v on the P55-UD5. Fingers crossed!
Thanks for sharing dude,
Sounds like the BBSE may do better for raw, unadulterated, OC'ing.
Might lift my spreaders to see what "exactly" I've got! :)
About to finally use all 4x 2GB sticks that I bought about 1yr ago for my P7H57D-V EVO!
I'm tempted to lift the heat spreaders off mine now to confirm my suspicions. I'm 90% sure I have PSC ic's on mine.
BBSE dont work well at all. Gave up. I had windows stability up to 2200mhz, prime just dropped a thread within 3 minutes.
PSC are the way to go.
Also my P8P67 Pro now needs to go back. I put AI Suite on (after multiple patches to get it installed) including fan xpert. As I rebooted after the install all my fans turned off. A full cmos clear has got the cpu and mem fan headers back (but q-fan no longer works, full speed only) but the chassis fan headers are not working at all. Coupled with my hypers not being stable and the lack of general stability I think I may try and switch for the UD4. Most problems I've come across seem to be bios related on Sandybridge - I cant help but wonder if UEFI isnt still a little immature. I guess only getting the Giggy board would answer that really.
Duly noted...
TBH I'm a little paranoid about prying the heat-spreaders off mine.
I'm no hard-core overclocker, so no "biggy" if I've got BBSE :)
I'm at least 6mth off upgrading to SB :(
The trick is to not use much pressure - let the tape slowly peel itself off. Use the tips of your thumbs along the bottom (gold finger) edge. Find a side thats lifting easier than the others and go for it. If they're all stuck down well just forget it ;).
Cheers mate, but once they're off, they're not going stick back on as firmly are they?
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 ;).
Noticed a strange problem on AMD with 4x2gb G.Skill ECO.
They perform really well:
http://digilander.libero.it/m4puni/p...7_Prime_1s.jpg
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?Quote:

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.
^ sorry to hear that mate, hope you have better luck with the next MB!
I tested the Asus one last time before taking it back and the damn thing worked :lol:. 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.
http://img822.imageshack.us/img822/2060/dsc8232z.jpg
And 1.65v DRAM voltage(didn't try lowering it). Need more testing tho.

Nice :up:.
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.Quote:

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...

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 :rolleyes:Quote:

P67 is the key dude. Its a clear +150mhz with these PSC eco kits compared to earlier chipsets.
I lied on my sticks.....
I undressed them and they are 100% BBSE
I think these are gonna be my next purchase.
They're cheap and clock well :).
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 :shrug:
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.
Do you guys think these would do 8-9-7 cmd1 at 2000, for an amd?
Or would it need something like 7-10-7 timings?
I don't know but I think either way it would ok'sih probably.
I think these are only $60, and if they could match or beat what I got now (8-9-7 at 2000), then I would definitely go for it.

My BBSE kit sucked, but then it sucked on P55 for high mhz too, so its possible ive just got a crappy kit there. It barely did 2000mhz @ 8-9-8 on P55 and had to slam the timings to get 2133mhz prime stable on P67. Something like 9-11-10.
You dont get as much extra on BBSE kits compared to PSC, but if you start off with a great kit anyway then I would imagine theyre at least as good as the PSC kits.
I've not seen a PSC kit yet that wont hit 2200+ at decent timings, whereas people have had issues with BBSE.
Bios updates may help that - its very much manufacturer dependant.
To get the best out your kits the following works pretty well:
For BBSE you only want either Gigabyte or ROG.
For true Hypers you want Gigabyte, foxconn, evga or ROG.
For PSC you want Asus mainstream or asrock.
Highest bin BBSE would theoretically do about 2000 7-8-7 on P55, while PSC did 6-9-6...
Once up in 2100+ range on P67 I would be they could only pull 8-9-8, and that is like a super binned kit.
PSC should do 7-9-7 there, and beat BBSE.
Problems with ECO on AMD, they dont like the 1:4 div. much. Your better bet is the 1600 C6 RipjawsX, last I checked they were $80. They wont be as good as Flare, but if you are lucky you are looking at 7-9-7 to 7-10-7 at 2000.Quote:

Still running this stuff since about the time the first post came around, on my Phenom II X3 720. I finally got it stable at 1600 7-8-7! Stupid memory controller...
I had this stuff running with an i7-860 for a short bit, had it up to 2100 8-9-8. Got a second kit, and it clocked like ass, so I immediately got rid of it for free. I wish I didn't :P
So there are 2 types of IC's for this stuff, PSC and BBSE. Both are pretty decent, but one is better than the other...Which is the newer one? (say, if I bought a new set off Newegg), and what were they a couple years ago? Last time I tried taking heatspreaders off = 1 IC came off almost too easily.
Havin' fun with this good old kit, 1.65v :
http://tof.canardpc.com/preview2/da4...672e5798f7.jpg
It responds well ! :up:
32M is more difficult though :D
/necro
Very nice with 1.65v!!
This thread is 3 1/2 years old. That's awesome :D :D
I sent a kit to rma today because it couldn?t do specs :shakes: - this is not quite as awesome as the result above :rofl:
This is 2x2 Gb or 2x4 Gb?
Looks like the same chips as my Geil Ultra Series http://www.geil.com.tw/products/list/id/35
This stuff is good for 1700 6-7-6, 1900-2000 7-8-7, or 8-9-8, and up to 2200 on 9-9-9, but hard to find anymore of them now. It used to be very cheap though.
The problem would be looking for another 2 sticks if I ever swap to a quad channel board with 8 dimm slots, as I want to keep this ram.
Is this stuff still quite good, even on the latest Motherboards/CPU's?
I thought there'd be far better stuff around nowadays...
Then again, I guess RAM doesn't evolve as dramatically as other silicon.
This is still good stuff for X58, probably the second best you can get other than 2000 Mhz Cas 6, but I'd think there would be much better available for the newer sockets which can take ram up to 3000+ Mhz.
Just ran a few bandwidth tests on my rig, 30k+
http://i.imgur.com/DWx5dl2.png
I booted them on haswell at 2450 8.12.8.24 2T but superpi 32 gets stucked on loop 13
I cant keep mine 24/7 stable at 1900 though despite zero errors in 32m superpi, dont think its my ram but the IMC. 1866 cas 7 keeps going all day everyday, but limits my CPU overclocks.
It will also boot and run stable at 1600 Mhz 7-7-7 with just 1.43v, but I couldnt get 1600 9-9-9 stable at 1.35.
It does seem to be the same chips, maybe just that Geil didnt bin them for low voltage, but rather for the Cas 9 frequencies.
I wonder if Intel will ever do hex channel boards, would make a good next upgrade and I can keep using this ram.
Also for low voltage settings, I'm currently managing to run mine at 1866 9-9-9-27 at 1.5v and 1.35v QPI, just testing to see if I can get lower CPU temperatures with lower QPI (7-9-7 1866+ needed 1.4-1.45v QPI).
These older chips are great for their voltage scaling, you can set them up however you prefer, low volts and timings, or high volts and tighter timings. No difference to CPU temps with just higher Dram volts so I'll run 8-8-8.

Ok, In my search for lower QPI volts, I've now got all the following 24/7 stable:
1.35v QPI / 1.51v Dram - 1875 9-9-9-27
1.35v QPI / 1.64v Dram - 1875 8-8-8-24
1.45v QPI / 1.67v Dram - 1875 7-9-7-24 (7-8-7 is only bench stable but Bsods after a while, same with 1900 Mhz).
Dont think I'm going to run 7-9-7 anymore, I knocked 3-4 degrees off my CPU with the lower QPI voltage.
