Was using official F8 BIOS. Flashed back to beta F8D, and now the RipjawsZ seem to work fine. At rated specs with tightened subs, and running memtest right now.

What are the 5th-8th digits of the serial numbers of your Ripjaws (from the label)?Quote:

Have to assemble an IB rig before I can test them, but hope to have that started, if not finished, by tomorrow.
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.

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.

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.

Running these at 1.550V.Quote:

what does it matter how low the voltage is?
Lower operating temp, longer life, etc...Quote:

Mine are stable same as above with 1.55V so far.
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

me like :D 25522 Read is not bad at 4690 cpu and 2500 ram :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.;)

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.

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:

yeah there are a lot of other timings and fun with this memories, will try more tomorrow.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:

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...
