makaka, can you post some everest scores?
what chipset is that with? x38?
:D Was a lot of work, really, but finally I got these sticks 32M stable at 1.92 Vdimm on Maximus Extreme:
http://img100.imageshack.us/img100/2...1000mhzqu9.jpg
:up::up::up:
The chipset is the good old p965 . motherboard asus p5b-e plus .
memory timing 5-5-5-10 (1000 mhz)
As reference here is a screen shot of my current super pi @ 4 ghz 500(5-5-5-15 , 1:1 ) x 8 .
11.29 vs 12.33 :clap::clap: (nice DDR 3 boost)
hmmm weird, i thought pi gets a bigger boost from extra mem performance...
you make it sound like your ddr2 1000 555 is as fast as ddr3 at 2000, well, its definately not ;)
what this really shows what we all knew already, pi has become a cpu cache benchmark :D
compare the everest results, mike has a 50% higher read bandwith and 50% lower latency...
well i am trying to find now the exact equation for DDR2 vs DDR3 in super pi .
Currently 4100 mhz with 512 mhz memory (5-5-5-15) was slower , i am re benchmarking now with 4150 mhz (518 mhz same latency) . let see how much boost and cpu frequency give this nice DDR3 .
Now 4100 mhz cpu + 512mhz ram (5-5-5-15) < 4000 cpu + 1000 mhz ram (8-8-8-20)
:up:
4150 mhz + 518 mhz memory should result in slightly better result . But my memory crapped out in the loop number 17.
This geil memory do not like high voltage with 2.3v this memory was instable @ 518 mhz and even @ 500 mhz while it is completely stable @ 500 with 2.1 v.
So test proof that :
DDR3 1000 (8-8-8-18)+ 500x 8 = DDR2 518 (5-5-5-15) + 518x 8 cpu .
about (+140 mhz) cpu + DDR2 (500) is equal to 1000 mhz DDR3 memory in super pi .
unfortunately I am not able to view the image of your run atm - but don't worry to much about trfc - you won't loose too much as long as your mobo is all nice and tight
965 is like pre y2k technology -waaay slow in mem perfromance - forget about comparing everest.
Malaka - it's hard to compare 1ms; or in fact any SuperPi without knowing what OS tweaks you and the other person are using. It's easy with a couple of OS tweaks to smoke someone who is running a "much faster" base system, keep that in mind comparing X with Y.
1m is all about CPU cache...
But you're right Saaya -seems like SuperPI is turning more and more into a CPU cache benchmark - it's hard measure real world performance improvement from memory bandwidth with CPU cache taking over a lot of the work; espcially when you are trying to tighten your secondary timings, for tests like SUperPI. Maybe we need 64m test :p:
Good that you don't - you'd prolly smoke most of us if you were to go cold!
Yes the right motherboard is really key for DDR3 performance - I just received 2 more sets of D9JNL and are hitting pretty much the identical memory clocks with those new sticks. It makes me really wonder how well this memory would perform with an even better board!
CAS 8, CAS9 or even CAS10 results could potentially blow our minds - if there was a board/NB which could cope with it.
:D Now I got it 32M stable tRFC 72 @ 1.92 Vdimm:):
http://img100.imageshack.us/img100/2...1000mhzqu9.jpg
:up:
someone can explain me what voltage for default setting mean ?
i am explaing better: in the cellshock box i found: 1866mhz at 1,7 / 1,9V.
It mean that i can find modules that can stay at 1866 with 1,7 stable or modules stables at 1866 at 1,9v ?
or is only a range for warranty ?
its actually 1.7v-2.0v :D
and yes, of course some need more volts than others, but yeah, the 1.7-2.0v is mostly about warranty :)
All kits should run 1866 888 with 1.8v, some even with 1.7v :D
Why is my bandwidth so low ? bios p04 and p1 p2 enabel http://img507.imageshack.us/img507/6...0mhzhq7.th.jpg
wow, thats weird... your score sucks big time man! no offense! :p:
i have no idea why... i DONT think p1 and p2 are really enabled...
This looks more like a score without p1 and p2... actually even then it looks very low :confused:
790 is such a weird chipset...
Ive seen some awesome bandwidth results at 1600 777 that were better than 1800 777...
Something is very weird about clocking mem and fsbs high on 790... it seems the performance actally gets worse the higher you go.
Dinos insists its not the case if you enable p1 and p2, but from what ive seen even with those enabled and tight timings, the higher you go, the lower the scores seem to drop..
Can yo run 1866 777 please and post that everst score?
:D Mike - You still owe us the 7-7-7-14 pics on ME promised in Your first post......:p:
http://img228.imageshack.us/img228/5416/933km9.th.jpg What is this now i am real confused
hmmm almost the same score as mike had on the x48 board at 2000 777...
well, what can i say... 790 is... weird...
what about 1866 888?
Id say go for 1866 888 and then up step by step and check at what point performance degrades. then use baredit and make a register dump at both speeds, before and after the perf drop.
use examdif or another tool to compare the dumps to see what register change.
then change one register after the other and check what happens... and with some luck you find what settings change that degrae the mem perf at higher speeds, then you can tweak the mem perf to scale even at high speeds.
is there a clockgen or something?
if yes, then use that tool to increase the fsb and memspeed from within windows. the perf should scale the same if you do this as register should remain at the same setting.
http://img247.imageshack.us/img247/6...cas8bo6.th.jpg 8.8.8 18 no clockgen straight from bios
k... hmmm well idk man... id say... use clockgen and try to up with clockgen bit by bit.
That way perf should scale and not degrade the higher you get.
In case you have the time and are curious you can boot in steps and check how the performance degrades or changes, and at what point it changes.
:D I never use clockgen or getFSB - all my results are bootable....:p:
Give me a few more days - I am currently in Costa Rica, enjoying the beach :D
790i results...argh what a weird board. I think it very very important to have the right memory divider - prolly only linked really works well. I had lost lot of mem bandwidth going from 1600 to 2000, leaving everything else unchanged ( CPU , timings etc. ). Can't say much about 790i - just that it has been a pain so far - but I'll give it another shot soon
:D Wish You nice holidays Mike - enjoy it - life is too short........:p:
I've been in Venezuela in February - mid & south America is always worth to travel there......;)
SRY for :off:
Against all odds I managed to get these sticks run @ tRFC 60....:up::

:welcome:
I am not getting anywhere with my CellShock Blue :(
Before I installed the CellShock Blue, I had the following setup:
Asus P5E3 premium (bios 0503) + QX9650 + Corsair dominator PC14400
multi: x9
strap: 333
fsb: 433
ram: 7-7-7-20 1T
dram static read/write: enabled
clock twister: stronger
PL: 06
vcore: 1.41
fsb: 1.24
vdimm: 2.0
nb: 1.63
I have been rockstable with the above settings (16h+ hours prime95), see:
http://img403.imageshack.us/img403/6...pu39ao7.th.jpg
So I just replaced the Corsair dominators with the CellShock Blue, changed the timings to 8-8-8-16 and vdimm to 1.8V.
I immediately had tons of errors with memtest86+ in test #5....
And this is only for a frequency of 1730MHz :-(
To get rid of the memtest86+ errors I had to:
- go 2T instead of 1T,
- put dram static read/write to disabled,
- change clock twister to moderate
- drop the PL to 07
And I am still not completely stable because prime95 failed on 2 of the cores after 1 hour.
Also the bandwidth si so low compared to the dominators (went down from 11.5k to 10.3k!).
I have tried various vdimm from 1.7 to 2.0 with a step of 0.04V.
Memtest86+ test #5 gets better with more volts, but then errors start to pop up in other tests (#2 or #3à when vdimm > 1.9.
How can this be?
I just can't run the CellShocks Blue stable at 888 for only 1730 MHz :confused:
as i said via pm, the only thing i can think of is subtimings?
your results dont make any sense whatsoever to me... something must be very wrong...
id say start again from scratch, load setup defaults and then clock your way up.
make sure you use slots 2 and 4 and high vmch...
and try the sticks in single channel?
maybe you damaged one of them somehow?
Impressive DDR3, but i love CS D9GTR (PC14400) for drawn timings ;)
Thanks for your reply Saaya.
I don't know what it is but as you said, something is really wrong...
The CellShocks can't do 1T even at 1700 cas 8...
I have not such problem with the dominators, which makes it difficult to accuse the MB or CPU.
I will tonite test each stick individually to see if the fault is really due to one of them.
I can't believe the sticks got damaged.
I received them back from RMA last friday and all was packaged very properly. I have been very careful with vdimm and I didn't go higher than 2.0V.
did you already try to set the bios to setup defaults after installing the cellshock mem?
Hmm.. Sounds almost like the issues I had with similar kit on P5E3 WS Pro.. :shrug:
Tested different mobos and eventually switched, that did it for me :yepp:
did you also use another memory kit in the same board that featured xmp?
i heard that when switching from an xmp kit to a non xmp kit there are weird bugs.. several people mentioned this already...
they reset the bios and suddenly it all works fine... hmmmm must be some memory timing id say...
I am still investigating.
The corsair dominators that I own are indeed the Intel XMP version, however I never enable xmp in bios and always set the timings manually.
I have tested each stick individually at fsb 466 8-8-8-16 1T and 1.86V, no problem.
When I put the 2 dimms in slot #0 and #2, I have to move PL to 7 and clock twister to moderate otherwise I can't post.
Then no memtest86+ errors but unstable system (prime95 fails or freezes my system within 10 minutes of stress).
It could very well be that my QX9650 has a fsb wall < 450, so I am not accusing the CellShock blue kit.
The CellShocks seem to be very sensitive to voltage, if I go higher than say 1.9V I will get memtest errors.
The kit cannot do 7-7-7 1866 no matter what vdimm and vmch is applied.
Saaya, you keep mentioning sub-timing, what would you advise me to change on the P5E3 premium?
your using the p5e3 premium and slots 1 and 3?
then that might very well be your problem :D
go for slots 2 and 4 man! :)
subtimings... i dont have a p5e3 premium... never had one...
id say check what mikeguava, sioux and metro posted, they all used the 1866 blue kits and the premium iirc :)
Thanks Saaya. Well I tried slots #2 and #4, sorry my post was not clear.
The best I could do is 1866MHz | strap 333 | 8-8-8-16 1T | PL7 to run with no memtest86+ errors.
This was with vdimm = 1.86V.
With vdimm < 1.8 or > 1.9 I get memtest errors so I would say the ram is on the verge of stability and very sensitive to volts.
My system is unstable at fsb=466 and I guess that's due to my QX9650 not handling high fsb so I can't blame the CellShock dimms on this one.
sure, i havent seen many qx9650s do better than that fsb wise... this is pretty much where they max out
hmmm.... ok, now try 777 with 1800 and work your way up, and see how high you can push vdimm :D
you should be able to reach about the same speed with cas7 :)
its normal that with 2,0v @ 1866 memtest give me a lot of errors ??
mobo is x48T-dq6 and settings are 467fsb divisor 1:2 strap 400 (4,00D) PL 8 and overvoltage to NB is +0,3v
have you tried with lower strap? set it to 333.
depends on the chips... some like 2v, some dont... and it depends on the timings you run, the difference between the max vdimm for relaxed timings and max vdimm for tght timings isnt as big as for gtr/gts anymore, but its still there.
and it also depends how much vmch and what slots your using.
on asus boards slot 1 and 3 dont scale with more vmch and act... weird... with vmch and vdimm bumps
slot 2 and 4 scale properly with more vmch and vdimm :)
on gigabyte boards 2 and 4 are better as well afaik, but they act weird with more vmch, like slots 1 and 3 on asus boards
on the blackops ive run some sc tests and it seems all slots clock really well
lol but on sticks there is write : 1866 8-8-8-16 2,0v id they dont run @ 2 volts at that speed i think i go for rma.
2,0 is garanteed voltage...
yeah there are definitely excellent sticks and not so good ones, that buyers like you and me will get...
I have already gone once through rma and received a replacement kit that is still miles away from the expected performance.
And I can tell it is not my CPU/MB/whatever because my corsair dominators totally outperform the CellShocks on the same system.
i thinking that black ones are better...
so, 2v is not guaranteed, and 2v isnt 2v anyways, on some boards 2v in bios is 2.1v real...
thats the voltage range you can use without losing warranty, it doesnt mean the memory will scale up to that voltage.
more vdimm isnt always better, ive had some sticks that could run close to 2000 cas7 with 1.9v, but more than 1.93v and they only gave errors...
now think about it, what do you want?
sticks that can run with a certain voltage or sticks that can run a certain speed?
if all you want is sticks that run with 2v and you dont care about the clockspeed, go ahead and ask, and im sure they can send you some :D
and you know what i think? there are people who know how to push their memory and reach really nice results, and there are people who expect their memory to be plug and play and get the same results or even better than the best results they have seen with this memory so far, and if they dont, they will claim its bs and the other results were with handpicked hardware.
strangely your the only guy with this problem...
corsair has very well programmed plug and play spds, and yeah, they have some nice memory as well... if you have a quadcore cpu which limits you to 1866max clocks, and you can run 1800 cas7 with your older corsair kit already, then why did you buy a JNL based kit anyways?
buying a gtr/gts based kit would have made sense to try and get a good cas6 result, but JNL doesnt run that well with cas6...
some gtr clocks better than jnl, by far not all gtr/gts are as good or better than jnl
i saw review that was screeming 1000 c7..... i cannot boot in anyway at that speed...
i saw that if i stay under 1600 memories can stay @ 2,0v but if i go near 1800 with 2,0v its totaly unstable and i must use 1,95v.
but with 1,95v mem dont boot at 1000 c7 but 1000 c8 yes...
i thought this memory for theyr cost 270 euro will be better... 270 euro.... i saw people with ocz 1600 tha out perform ,y 270 euro ram with 120 euro rams.... cant beleive that
This is just unfair. I have played around all the timings, sub-timings, vdimms, PL and all. This is not what I call plug n' play.
The memory kit I have makes memtest errors consistently, can't run 1T, can't run cas 7 even at 1700, this is just fact.
If I replace the CellShock blue with the dominators, I can increase fsb, tighten the timings, go 1T and cas 7, and I have no memtest errors and I am rock stable.
Thanks for arguing that I am noob that can't handle the tweaking of memory. I am certainly not a pro, but neither I am noob expecting plug&play style.
Let me remind you that I got the jnl kit as a replacement by CellShock RMA, while I originally owned the gtr kit (8-7-6-21 1800). So I never wanted to buy the d9jnl kit.
Some really great info in here fellas! Im learning alot about DDR3 since I will be doing my first benches with it this week (790i + E8500 + 8800gt SLI & 8800gts 512 SLI).
Sayaa I especially appreciate your explainations of how to find and edit registers! I have been trying to learn about this subject also, but most public info is about 965 strap tweaks.
aerie: There is no guarantee your RAM will run at tighter timings and higher clocks than rated. You stated a reviewer who had it at CAS7 @ 1000Mhz when the kit is rated CAS8 @ 933Mhz. Just because some people achieve these results is absolutely no guarantee every kit will. Just be happy you own a kit thats selected from the top 20% binned kits! Also getting your RAM stable at such settings requires alot of patience and tweaking, not of just your RAM timings/voltages, but also chipset/mobo voltages.
1866mhz 8-8-8-16 2,0v always blue screen nice....
and i am not a noob i have 150 points and i know how to manage a motherboard
my bad... if you cant get the kit to run fine no matter what, then send it back and get it replaced. i just find it very hard to believe that 99% of cellshock customers dont need an rma and you happen to have 2 bad kits in a row out of bad luck... but maybe you ARE that unlucky :P
in this case, the thid kit HAS to be good, cause nobody can be so unlucky to receive 3 bad kits in a row with the high testing standards cellshock uses.
your welcome :toast:
pm before and felix88, they might be able to give you some hints and tips on tweaking registers :)
exactly! it seems a lot of people look at the best results somebody managed to achieve with one piece of hardware and then think every piece of this product line can reach the same speed/performance...
and even the best kit out there might suck on one board and rock on another board... and as i said plenty of times, it doesnt even mean the board is bad, some boards work well with one kit and suck with another... theres a lot of weird variation from one board to another... between 2 good boards you might see a variation of up to 50mhz for one specific kit, another kit might work well on both etc...
why are you bumping 2v through the mem for just 1866 cas8? they should be able to run that speed with 1.8v or even less...
Thanks for considering that it might actually be a problem with the kit, and not me/my mobo or my CPU...
I agree and admit it seems impossible to receive two 'bad' kits in a row when the quality testing at CellShock has such high standard and good reputation.
This is why I keep on testing the kit on my system (3-4 hours each evening) to be 100% sure before I send it back.
I am exhaustively testing sub-timings and clock skews for a wide range of different vdimm in 1.7V-2.0V.
you shouldnt need to adjust clock skew etc to be able to run at stock speed...
i dont want you to get any more frustrated or annoyed... just send it back and have them check it for you.
if the kit is fine they wil send it back riht away, and if its broken they will replace it for you.
your from italy right? just contact gennaro and im sure you dont even need to send it to germany for an rma, he can probably check the kit for you in italy and maybe he can give you some tips to get it stable. i still dont think there is anything wrong with the kit... it must be a bios or bios configuration thing...
so whos got the nerv to recomend this sticks at this moment?
Hello. I address on this forum for the first time and I hope to me will help with my problem.
My configuration:
E3110
X48-T3RS
2x1Gb Cellshock BLUE 1866GHz
XFX GTX260 XXX
Silverstone DA650
I CPU seems stable in OCCT in a current of 6-8 hours 450x9. My memory allows to be loaded in OS using a thong 400/1600 with pressure 1.93-1.95V... But is extremely not stable. Pressure increase leads BSOD or "the black screen" stiffens...

I have left other values by default. Whether my options are correct? What should I change?
Thanks.
I am sorry for my bad English...
I will be grateful for any assistance with this forum...
Perhaps I should change your memory in the BIOS, but many settings DFI does not allow me to do it right quickly.
I spent a long time, but had not made good progress.
I would like to run 1800CL7 1T and 1977 1T 24\ 4 at 1.95-2.05 volts.
http://www.total-oc.com/forum/galler...7&image_id=173
http://www.total-oc.com/forum/galler...7&image_id=174
Today, I checked the memory of the default through Memtest of Windows - the result 0 errors...
http://www.total-oc.com/forum/galler...7&image_id=176
Have you tried them?
no i'm still with x38 & DDR2, so not so soon, perhaps later this year
perhaps x58.
and my mems are in rma, transcend is not continuing producing PC9600
so they've send the money back... i'm wondering what sticks should i replace
my old ones? Gskill Pi 4GB PC8800, PC9200, PC9600? or corsair 2x2GB?
OcUK have these on special for half the price of the black 1800s at the moment. I may dip in at this price, they look as if they could be fun toys. Still love my black 'uns though, they've been rock solid since I got 'em when Saaya first announced them.
Thanks, I'll be in London for a week -- I just love to see the beauties. I got mine from Ireland in TX. No Cellshock here it seems.
i was so used to DDR2 that at the begin i was finding it very hard to set cas 7
or even cas 8 at 2000MHz... :shakes:
holpefully guys like do awsome work for the community.
thanks a lot mikeguava :up:
i'm up to set 5GHz with E8600 at Cas 7 2000MHz 1T performance level 7
we'll see what results i can pull of with x48. i'k not very interested in stability at this point
later i'll do some prime but at lower frequencies.
keep with the lessons up. :ROTF:
Heh, ordered them at 3:51 yesterday afternoon, got 'em about 10:30 this morning, here we go (about 1.9v real). lol at the SPD. I should add that NB is at 1.4v:

time with P5E3 Deluxe i think. i have passed Rampage extreme X48, P6T deluxe,
P6T deluxe v2, Evga classified X58 E6759 limited editon EC, and nothing
even came close to this 2074MHz at 8-8-8-16 1T and 2105MHz 9-9-9-18 1T
from 1.9v to 2.09v theres no limits with this asus
i belive they can do even better and imagine i'm using 6 sticks no problem.

With Rampage Extreme X48 my best was 2000MHz really
With Amd was a bit harder with the bios i was using at the moment
could not do better then than 1700MHz
For me besides the part that these are 1GB sticks and with 1.7v ~ 2.1v voltages
Cellshock blue are the best DDR3 ram i've ever tested
I haven't seen Cellshock for a long time. Why did they stop making new kits?
I think I've never posted my results with this kit in this thread, but since someone else brought it up again, I'll do it now! :D

They're not bad imho, but very sensitive to Vdimm. I could use a little more Vdimm with CL7 compared to CL8, going over 2.00V @ CL8 will just give a ton of errors in Memtest.
yup it's a shame cellshock stopped making enthusist top class memory.
The best RAM i've ever had and just this year i've tested Corsair Dominator GT PC12800 7-7-7-20, GSkill Pi PC12800 8-8-8-22, OCZ PC15000 9-9-9-24, G.Skill ECO PC12800 7-8-7-24,
OCZ Blade PC16000, Team Elite PC16000 9-9-9-24, and other low end sticks
