I should get my 2600C10 kit by tomorrow. Will report back tho.
Here is mine from http://www.memoryc.com/computermemor...hzdualkit.html

I will check them later.
are the AB40's single or double sided?
if they'll clock 2600+ i might have to order another set.
no, only single sided...At Bulldozer ended at 252x MHz 10-12-12-1T, next I will testing different timings 11-13-13, 10-13-13, 8-x-x
Got the 2600C10 kit. It's Samsung double-sided.

Taking it higher screws my raid as does more tight timings. Waiting for a new bios or board:cool:
My 2600C10 kit topped out at 2706. I hardly get it to POST. Always get stuck at code 23.
IMC is a weakest link here.
GOT a SingleSide 2400 10-12-10-31 Today
2400 9-9-12-24 1T 1.75 is the funniest timings we can see on Z77 :D
http://www.theoverclocker.it/hiwa/24009-9-12.jpg
my kit is dead :-(...I got BSOD in superpi32M at 2560 Mhz, then PC no boot, only DRAM led blinking. Others RAM working at board, so really dead RAMs :-(. I had only 1.75V in BIOS at Crosshair V Formula.
yours were samsung ?Quote:

Sad....
what's you exact timing and sub timings? they are all easy goes to 2500 Cl10 but over 2550 is not easy for them.Quote:

Think those are the same as the Tridents? Trying to find a double sided kit that will do 2400Mhz + for benching without the need of 1.75V+ like BBSEs or whatever.
I had the 2133 version of that ram and they did 2400 no sweat. I also managed 2600 on the 2133 kit.
Those are currently the Shell Shocker special at the egg and are on sale for $80 per 2x4GB kit w/free shipping right now.Quote:

This is a good deal. I'd jump on this with the coupon if I didn't already have 4 of the 8GB sticks.Quote:

Very interested in your information/results.
I got 2600Mhz 11-13-13-34-2T pretty easy, Spi1m-4m and everything else stable. But get "Not convergent in SGR" with 32m. Tried 1.7Vdimm and 1.125Vtt/1Vimc.
2400Mhz is rock solid though.
Digits are 1500 for me as well.
http://s864.photobucket.com/albums/a...wsZ%202400Mhz/
I dont think they are samsung 30nm, cause the 30nm ICs are physically so much smaller. If they are Samsung, they would be HCH9.
Since they are single sided, would it be better to get another set for 4x4? They dont seem to have much OC potential, so if 4x4 would run the same speed/timings, would it gain anything from interleaving?
I did get two sets, so it will be interesting to see how to do running all four of them. Turns out the two sets are sequential in serial number...just as if I had bought a quad set.
Are you using the motherboard in your sig, or something else?
3770K + Z77X-UD5H.
Tightened all the subs to about the lowest possible, and they passed 20x LinX AVX.
2 dimms vs 4 dimms. Had to loosen some sub timings to get 4 dimms to even post. Even still, 4 dimms is a bit faster. Read bandwidth is lower though, but copy, write, and latency is improved slightly.
Attachment 127630Attachment 127631
No more than these kits clock I think a better choice are the 8GB sticks.
What are your sub timings, and bandwidth?
Back to two sticks to see how low the voltage will go. Down to 1.6Vdimm.
Attachment 127634
Running these at 1.550V.Quote:

Lower operating temp, longer life, etc...Quote:

this IC can run tight tRCD but can't run tight tRP
they Hate high Voltage even 1.65 if you want go high i got easy +100MHz than Default with 1.60Vdimm and when i tried 2520 i should go for 1.68V means IC doesn't scale well after 1.6V.
they can pass 2400 10-10-12-31 2T with only 1.52V SuperPi 32m
2500 10-10-12-31 1.60
check MemTweakit to know how to set.

Playing with sub timing i want to try tune only 2500 tightest possible at 1.6V only
lets see the performance, now the game is funny :D

This module is using Samsung 4Gb density ICs -- K4B4G0846B - HCH9.
Team Xtreem LV 2133 uses this IC as well with Samsung original 6 layer PCB.
This guy is a voltage-hunger when running at CL9, mine did 2600 CL9 at 1.96V. Your G.Skills with 8 layer PCB might do even better.;)
Attachment 127693
Also 2400 10-11-12-24-1T at 1.55V is stable, OK for daily use, better than Hynix ICs.
all 2nd and 3rd timings are tighten as PSC chips, tested under Windows 8 RP.
Attachment 127694
Amazing ICs!:up:
nice memories u got there, i don't think they are same as mine
If you can run tRRD and tRTP @ 4 and tFAW @ 16, you should get a nice boost. I find those settings make a pretty decent difference with high clocks.Quote:

Nice read guys, built a new gaming PC the other day, specs below. Had a quick play around with my memory timings as it was only running at 1866, so bumped it up to 2400 and stock timings, everything running well :) pushed up to 2600 and no go wouldn't boot... will play with the timings tonight try and get them a little tighter, still at 2400 as don't have option for 2500 I'll try for 10-11-11-23. Also OC'd the CPU from 3.5GHz to 4.8GHz @ vcore 1.3V which was stable, 4.9GHz crashed in testing... will post results later
Can someone please upload the spd of these memories with spdtool or thaiphoon burner ???
I need it for my low profile samsungs dimms . I'm sure a lot of people will appreciate this also .
Thanks ! :)
i bought myseflf this kit too and i acheived to do this at the moment:
http://img36.imageshack.us/img36/534...ramtweake2.jpg
I dont know which chips they are but they are single-sided black pcb. They are rock stable 10-12-12-27-1T @ 1.59vDIMM
I am not able to boot to windows at 1300Mhz, yet.
I did 6.37 xxx but with 2x4Go G-skill perfect storm (F3-17066-CLT9-6GBPS) 1100Mhz 9-9-8-1T.
Lovely mems :D
New one TridentX...Now double sided and Samsung chips...June 2012, 15000. Hope, double will be better than single sided...
Really? Has anyone else found new Tridents to be double sided?
:D
I thought, new as my second kit 2400 MHz TDX:)...
The first 1 or 2 batchs they made where with samsung and double sided but all the kits i have bought for the last 6 weeks is with hynix and singel sided but the 2666mhz kit is samsung and double sided
Just purchased this kit from Newegg to pair with MVGene and 3770K. Will post results as soon as I receive.
Not sure about that 2666 comment mate, feels more like hynix looking at the clocks I'm getting...Quote:

I prefer Samsung Team Xtreem 2600C10 as they could do 2800C10 stable as low as 1.78v whilst the Hynix RipZ 2400C9 needs 1.88v for 2600C10. That was on Z77 platform.Quote:

I have had 10 kits of the 2400mhz sticks in my hands for PCs i have build and none of them where samsung but hynix and singelsided and the 5 kits of the 2666mhz sticks where all samsung and double sided thats wy i made that statement and i am talking about the Gskill TridentX kits

http://www.overclock.net/t/1268061/o...#post_17682371
Well, how do you know yours are Samsung? I was just going by what I've seen so far, but I stand corrected, some of the single sided kits are probably Hynix chips.Quote:

On the other hand they can do those weird timings ( 1200MHz @ 10-10-11-27 @ 1.5V ) which I've only seen on Samsung so far. Then there were a bunch of 0000 kits, and now they are marked 1500. I have no ideas what 0000 is, but hokiealumnus' 8GB sticks (double sided) are marked 1500 as well and they can run the weird timings ( 1200MHz @ 10-10-13-26 @ 1.65V ) that are typical of the Samsung 4Gb B-rev. IC. Another proof is Tapakah's kit, 8GB double sided sticks marked 1500, he can run those weird timings as well ( 1200MHz @ 10-10-12-30 @ 1.55V ) and you can see SE hidden under the GSKGSKGSK which means it's a Samsung IC.
The only 2600C10 kit I have seen was posted in this thread, retail kit, marked 0340, Samsung ( 4GB double sided ). Then I know about another retail kit that is marked 1500, 4GB double sided, should be Samsung too by results and the looks of the IC.
The 2666C11 were first marked 0240, Hynix, but I don't know if they were single or double sided (4GB sticks). It was vr-zone's review kit. Then there was trans am's kit marked AB40 where you can see half of the H9C under the GSKGSKGSK, so it must be Hynix (4GB sticks). Madshrimps has a kit that is marked AB40, 4GB double sided, too.
The only 2800C11 kit I have seen was marked 0000, just fyi (4GB sticks).
Do you have any info about the part number? How did you determine which were Hynix and which were Samsung?Quote:

Do you know if the AB40 on the 2400mhz serial number means they are good quality? Or did I get a low binned cheap set of ram???Quote:

2400? if its double sided its good, if not, its crap.
To determine Samsung vs Hynix
How about this?
Try run 32m @ 2400 9-11-10 @ 1.65v
Hynix can pass 9-11-10
Samsung fails 9-11-10 but pass 9-11-11 only
My Team 2400c9 rams fail prime at XMP profile 1.65v, with more vccsio/a it passes but it's getting a bit high for me ...
:(
Single sided but I have read that the AB40 designation makes them good. I'm confused about the IC naming and identification.Quote:

Samsung or Hynix I don't think it matters much since both companies are making high quality ICs. The weakness seems to be the single sided double density sticks. The double sided kits are lowerer density ram and as such are able to conduct electricity better and dissipate heat better.
All the best kits that I have seen reviewed or talked up about are the double sided kits.
I have a single sided "AB40" 2400 MHZ kit that I am going to play with later on today. I already have a feeling they are going to be duds. I hope not but its hard to be optimistic over the physics of it all.
I'm happy with my single sided "AB40" kit. Not sure what the ICs are but they are fast. Run 2400mhz XMP profile at 1.525v.Quote:

they wont do much over 2600 though im betting.

I tried manually over clocking 3 different sets of Samsung 30nm 5GB kits and fastest I could get them was 2133mhz at same 4.5GHZ with i5-3570k. 2600mhz is a nice speed for my cpu with Z68chipset MB. I had a set of G.Skill CL9 2133mhz and fastest I could over clock them was to 2200mhz.
Not sure if Z77 is better than Z68 for over clocking ram. I may have a golden set of Trident X 2400mhz single sided ram.
if you're still using Z68, then yes, you're being held back by the chipset.
Got a 2400 kit from the Egg last week, double sided. Haven't pulled the spreader off yet, but one came from the Egg loose already so I'll heat it up and see what is underneath.
0240 is definitely Hynix, it's part of the old numbering scheme and has been proven many times. Please post a link so I can check it out.Quote:

Mine will do 2600mhz with more voltage. I'm happy with the performance but I really want the double sided kit that is better.Quote:

I've thought about this and I really don't think the chipset matters. IMC on CPU seems to be more important than anything for over clocking ram on IB.Quote:

If you don't mind my asking, what are the 5th - 8th digits of the serial numbers on your first & your new kits (also manufacturing date - month, as we know the year :D )?
pretty sure these are all sammy's reefa. 2600 tridents samsung, and 2666 are samsung and hynix.
Weren't some of the original batch of these 2400s Hynix? I'm asking about the digits to try and make sense of what GSkill is shipping now...to compare the numbering with some of the earlier batches.Quote:

Edit:
For what its worth, at $70 per 2x4GB kit of 2400 rated ram, I'm OK if they are sporting Samsung and not Hynix chips.
Dang, I can remember paying $240 for a kit of OCZ 2x512MB with Samsung TCCD. These, if Sammies, would be a bargain compared to those. :D
i paid $130 for 2x1gb gskill 1000 hz cuz they were definitely microns.
this is when ddr3 was well and truely launched :(
i think id prefer samsungs, hynix is easy to find, the gskill 2133 9-11-10 kits are all hynix, and super cheap.
Just got my kits delivered...all June 2012, all "1500s"...all single-sided, so probably Sammies.
Will post back after I've had a chance to test them a little bit.
Both of my kits are June 2012, single sided Sammies
Like you said a few posts above, hard to beat guaranteed DDR3-2400 for $70 per 2x4GB kit. Who knows, maybe there will be a couple of real gems in there.
I'm guessing that's what mine will be then.
Yeah, most likely, seeing that's what the rest of us are getting. Do let us know, OK?
Yep, same as everyone else. Single sided, serial number starts with 122515000. But hey, Fry's has Corsair CMZ16GX3M4X2133C11R 4x4GB double-sided HCH9 on sale this week for $109!Quote:
