eight gen 1 vertex R0 :)
they seem to be limping along nicely...
What do you mean by this? I've never heard of such a thing.Quote:

only thing is if you set the packet size too high you will introduce stuttering into your video, if it is also coming across pci-e express ports. the videos packets will not be being recieved fast enough for good play, etc. Uber tweaking at its very finest, finding the good settings yield great results. shhh! dont tell anyone the secret :) i still havent done it yet on this run btw, havent had time yet for those last few percentage tweaks, jumping hurdles right now :)
Jumped up 5k points on PCMV only at 4.3 on my 920, i am up to 28k\
i need a 980x
http://service.futuremark.com/compare?pcmv=358183
nice results paul. on monday i will try to play with PCM i want my name on that list :D . maybe wont be the top cause of the MP but im hopping to be on top 20 somewhere :S
ty tilt, there is more to be given, having issues with either bad fanouts (gotta spare though) or a bad drive(spare for that too). will have to do more testing in the AM to isolate the problem. slowing me down big time. You should receive great results with those dual xeons, and the benefit of the dual IOH!
need SB these guys cpu scores are tremendous! cant wait to see what nizzen/anvil can do with their gear, some awesome scores inbound i am sure!
i want to try them on 5520 chipset to see how ARC works there and what will be the benefits of stock settings no Overclock for me
Hey Comp, great results. :up: Looks like the Areca 1880 is shaping up very nicely. Not wishing to derail the thread but the issue you raise on shared bandwidth on the pcie interface was one of the reasons I was excited about the Viking nand solution for a “ram” based SSD module. By all accounts it can send data via the memory socket and that gives a direct interface to the cpu. A memory socket seems to be the fastest interface on a mobo as far as I can see with nanosecond latency and transfer speeds up to 17,066 MB/s, but maybe I am missing something as it got slated in the news thread when it was announced. :confused:Quote:

the nand module you are speaking of is an excellent concept, and i am sure that one day we will see some implementation of that, as a matter of fact things are headed that way with memresistor (am i saying that right?) which could double as storage and ram at the same time, exciting stuff! i could be wrong, but i believe that the implementation you are speaking of is actually only using the power form the memory socket to power the device, yet it has a sata port on the side, and that is why they arent too excited about it, it still connects via the sata port i think. future versions will go over the memory lanes themselves. they do seem like very good ideas though. its crazy that a year ago everyone was thinking that getting the nand on the pcie was the way to go...but things are advancing so fast, now they are shifting to memory/ram implementations over the ram slots!
my testing continues today, only have made about three solid runs, having issues with my system...
You can try your theory out on a P55 motherboard. The P55 has the PCI-e controller on the cpu. I'd love to see the differences in latency from a P55 and X58 using a high end raid controller or even better an IOxtreme card. I mentioned this a while ago, but I haven't seen anyone draw any comparisons yet.Quote:

actually, steve-o arent you beating on a P55 right now? are there any differences with your 1231 that you could relay? or is it about the same?
Haven't even tried to see if the board would boot with a 1231 -it is a very little board - only one pcie slot and no onboard raid.
I will post a pic.
ty sir...
also on some testing of a different variety, after reading this form gfody at storage review.com:
i ran some more tests, and he is correct the 4k scales much higher, up to 482 mb/s with QD of 258. going to make up another graph to compare, but that will be in the future..still doing some pcmv action.Quote:
In my testing with Areca the storport driver doesn't scale past 32 where the scsiport scales up to 256. The storport tests showed significantly more iops than the scsiport at the same queue depth though. Sorry I don't have the data handy.
wow the 1231 prices just went down..
Ok so way off topic but CT asked.
Gigabyte H55N-USB3 mini ITX under cascade. :D
Almost as good an overclocker as the x58 UD7. :yepp:
I did need to do a silver pen mod to the 655K for CBB but other than that the mobo/proc is stock.
The H55N-USB3 looks to be a very little board expecially whne setting on the big cascade.

jesus lord that is beautiful :) MAN it is small...your evap dwarfs it...poor little board...:shock:
it would be very hard to get that card on there...
Thanks CT!
How's the pcmv progress coming - you know to use x64 of the app right?
The PCMV work continues, but i fear my ol 920 is just at the limits my man...here is a view of my cramped work area...need a bigger room but wife wont have it!
OF course some new firmware for the 9260 released today while im busy with other things....really need to get that on to try, with LSI new firmwares are UBER....

Good morning CT,
Looks like you have all kinds of room! :D
Yes 980 really helps pcmv suit scores no question.
You do have a couple excellent storage options between the 1880-4GB and the 9260, keep pressing and good luck!
yea, believe me i wont stop till i see smoke!:smoke:
All right Mr CT - you are making progress!
Looks like you just posted the #9 pcmv score - 28124 - very nice. :up:
You have the highest quad cpu pcmv score on the ORB - looking good! :yepp:
The 8 in front of you are all 980's - time for a new proc soon? :yepp:
Very nice work and much congrats! :up::up:
@ Mr Peanutskeeter - nice score 24769 with 980 at 4763?
#12 on the Orb! :up:
What are you using for storage?
just hit 29437 steve....still working my friend...finally put all ten vertex on the thing so here we go........dialing up the clocks a bit too..
EDIT:29796
http://i517.photobucket.com/albums/u.../goodasssd.png
All right! - #7 and only ~1k back from Mr Nizzen! :up:
and with a 920 - well done! :up:
If you went to a six core you would add 2+K to that score. :yepp:
edit - also - very nice AS SSD score too! :yepp:
things going well gonna have to call it a night/morning? though soon.
running the small stripes now, but the vertex do not respond as well to that...there is more to give from this setup i feel it!
also a few other things i will do differently tonight...
but all in all not a bad show from the 920..i can dial it up to 4.6 but i have to find my perfect setup first...I dont feel i have found it yet..
an excellent show though from the 1880! wow i cant say enough about this controller!
EDIT: just jumped another 500....i will add 2k without the six-core!:p:
Great resullts Computurd,
Can't wait for that 4GB stick :)
I've been playing a bit with raid-5, looks good as well.
I did try storeport vs scsiport, couldn't find that much of a difference, about the same number of iops @4K.
(scsiport was installed by default on my system)
@CT
You can pick up an ES L5640 on ebay for around $400. Cheaper way to get 12 threads compared to the 980x.
Now of course it prob wont clock as high as the 980x but you still be able to pull 4ghz.
i will make a graph if there is anything left after this kamikaze run i am setting up for :) there were some differences on my setup, but i only checked quickly, while i was doing other things. i will need to make a bigger test file..
@nitrobass excellent suggestion...with a six core i could make a run at the top three i believe. i should be able to get top five with a bit more persistence with this here 920...but that will not last for long I am sure without a sixcore. some of the HDD suites on the runs i have are better than any on there...
I've ordered a few more SF drives :), should be here early next week.
(should be interesting comparing to all the C300s out there)
I'll postpone my pcmv testing until I get the 4GB stick, looks like it's worth the wait :)
yeah lol...let me savor my rank for a little while at least:ROTF:
the 4gb and this controller are the ticket...
@anvil i believe your SF will torch the c300's
C300 vs SF?
could go both ways, as long as the SF drives are fresh, they seriously kick ass.
I haven't benched for a long time on my 980X rig, using the 920 rig for experimenting, the 980X rig still hosts the dual 9260 config. (about to try the new fw on one of them)
dual 9260 config just SOUNDS uber..
i dont think it will be as close with the SF v c300 like most do. In real life usage the SF just seem better to me....
EDIT: GL with the 9260 firmware...my 9260 is totally borked, have to wait for level 3 support on tuesday (holiday monday) the card wont even boot so there is no means of accessing it. very disappointing.
Famous quote from CT now applies to me - *grabs popcorn*
lol !
i have been benching for twelve hours, now it keeps crashing....gonna give it one more shot then rest!
@30394 btw..so close to nizzen...
tbh the points would happen if i let the GC run on the drives LOL pushing too hard!
Looks like the 1880 is on its way to the 980 rig, iops on the new 9260 fw are gone!
Tried to downgrade one of the cards and now the card wont boot :mad:
It's a wonder I've never bricked a 1231 - i have punished them severely.
Let the 9260 set unattached for a day or so - stray capacitance?
@ CT congrats on breaking 30K!
Even more of an accomplishment since gen 1 vertex and only quad core!
I think in the bot forum they refer to this as efficiency.
You have efficiency to the max!
I'l do that, going to try removing one of the cards first, might help as well.Quote:

excellent idea nizzen...but the price! how much is a BBU?
the 920 has only been at 4.45 i think during my highest run so far...i am back awake...Coffee!! and going to work on a few things. i agree a low clock challenge would be nice, however, i need to have about a 4.6 to hang with the 980 at 3.2:ROTF:
also bear in mind that i am running a venerable GTX280 so that isnt making things easy either.
tyvm guys for your comments, to be honest that was one of the best sessions i have ever had..great to get runs that good! also some credit to Tiltevros, he helps me very much with the thought process in video cram sessions, always my right hand man! thats what throws my schedule off when i tear off on runs, i have to live on Athens time! :)
I am not naive, however, I know you guys (tilt, nizzen, anvil) will come charging once you guys get your cards/cache, but still fun to strike while the iron is hot!
gonna do a big refresh with G3, might even pick up a proc (and definitely a GPU) so dont get lazy guys...:)
@anvil...that is what happened to my card as well! downflashing borked it. they have serious issues with that firmware, i am getting tiresome with LSI lack of support for enthusiasts. the most troublesome part is the lack of any type of access to the card, including the CLI...makes it an unworkable issue! one i am sure will end with RMA:down: doubly disappointing as i had a plan for it with my runs...you do have a server motherboard though?
Computurd,
I'm currently using them on my X58-UD7, I do have a few servers I could try though. (Dell)
It lists 5 lines of text, showing FW package etc, while initializing devices it stops with the message. (takes a minute or so)
"A discovery error has occured, please powercycle the system and all the enclosures attached to this system"
I've tried on an AMD system, same result.
Not sure what's going on, the new firmware might require some kind of action, there are a few options in the MSM that weren't available before.
I'm making a few backups and then it's Areca time.
I'll have to contact LSI somehow on monday, there must be a way to downgrade/revert to older fw or else it's 2 cards offline/RMA or whatever it takes to get them fixed.
well, enough about the LSI card...
I'll make a few posts in the FW upgrade thread.
GAH! i have the exact same error...i called LSI last night (their support is here in my city, of all places!) and they said i have to wait for tech support Level 3 and they come in tuesday. monday is a holiday here in the states!Quote:
A discovery error has occured, please powercycle the system and all the enclosures attached to this system"
What is so troubling is that there is no way to access anything, not even pre-boot cli...just noting to do but be irritated!
I also tried on multiple motherboards, all intel though but three of them. no luck!
have you tried with ACHI/RAID off?Quote:
I just flashed my 9260-4i with the latest firmware (dated 9/3/2010) and am having no issues on an Asus Rampage Formula x48. Note though that if I do not put my ICH in IDE mode and have the JMicron RAID chip on my motherboard disabled, I am unable to either install windows or get into WebBIOS.
Areca 1880, booting off of 2R0 X25-E, coming soon...
(about to HDDerase the drives as well as upgrading to bios F7 on the UD7)
:)
One week ahead of schedule.

awesome. that max latency seems to be an issue i have been running into as well with my card..can you do a everest latency test, to see if yours spikes? mine has intermittent spikes every thirty seconds or so...
EDIT: that random read is unbelievable :)2 x-25e?
2R0 X25-E stripe size 4KB, volume read ahead Normal
I installed the storeport driver this time, I used the scsiport on the other rig, not sure which one is the better one, will try.
I'll do a few latency tests before I start OCing a bit, the new bios on the UD7 needs some testing.
no read ahead on top, read ahead on bottom. hate to see the ten drive array get embarrassed by those x-25e's though. wonder if i have to many devices on, strangling the ROC? your random is much better. the latency spikes are less pronounced with the 4g. i take it you are still on 1gb right?

very nice guys!
I have found a point of instability here with my card
when i reach a certain benchmark (pcmarktv and movies) i am having instability/crashes which is causing me to not be able to run at speeds i have pulled off before with my chip. i have done it at 4.6 before. but with the new card no dice.
so in the course of things i turned off the alarm on the raid card. and it beeps constantly during that benchmark. looking thorough the raid cards error log turns up a low power error. so not enough power to the card via the pcie bus is causing the issue. so what is the setting that will actually put more voltage across the bus, to the card? any ideas?
it says specifically "3.3 voltage Under Voltage"
so i checked the 3.3 volts during run with eleet and it gets down to 3.14 during the heavy loads, when it beeps...
It could be that the power draw on the 3.3V line with the acerca and the oc is to high.
Whereas previously there wasn't such a power hungry card on the line.
Or the card is sensitive to small power dips when the cpu starts at 100% causing a momentary drop in voltage until the psu can compensate.
At any rate trying another psu might slove it as that one might have a higher current rating on the 3.3V line and/or a better/faster voltage controller.
Good idea. any other voltages you think i could tweak to fix it? also i have a sound card on a pci slot...do you think taking that off or disabling it would help?
Taking it out couldnt hurt.
remember software reported volts may not be accurate, try multimeter yet ?
no but not entirely sure how to check the 3.3v with my mutlimeter..noob at that...
how to measure using multimeter http://i4memory.com/f60/guide-using-...ly-rails-2632/
ty for the link eva. Bad psu! my zues 1200w has taken a shat all over me...LOL 3.3 v is borked. jumped the zues and used it for everything except mobo, then hooked my good ol pc&p 750 just to the 24-pin and it is running like a champ.
ordered a st1500 so i dont have to worry about it for awhile. gonna explore rma with the zm1200 and see what they say.
been just pounding with this thing trying to get above 4.3 for the love of christ, with a chip i have hit 4.6 with easily in the past, very frustrating it took me that long to pinpoint it. the only good thing is that i did tweak the hell outta the raid and card etc for ultimate setup...so now i am in perfect position!
well now we are working! up to sixth
http://service.futuremark.com/compare?pcmv=359435
I believe i can take 5 very soon...
Wow Mr CT - looking good! #6!
Looks like no question, areca 1880-4GB should be the new king of pcmv.
Come on Mr Nizzen, Paul's got you by 30 points!
*eyes corsair labs*
That's another 2k points.
That would be an amazing achievement considering you're on 920/water/gen 1 vertex. :yepp:
Planet was on areca 1680 with 11xR0 F200 200GB drives, GTX2 memory and 980 under ln2 at 5790! :shocked:
gah my ram is still loose, not dynamic switching yet, and haven't even hit the volts on this 280...ive got room my friend.
however, i just missed my friend mbreslin by 76 points..time to work on ram
nothing is impossible (besides you and mike :) )
lofty goals make for outstanding accomplishments
or horrible crushing disappointment LOL
alrighty enough for tonight.
got the number five spot by a few points. tomorrow it is really time to really work it. not being arrogant, i know the controller is making it easy :)
but i do have a goal :)
once others get the controller cache it will be game over for me :(
http://service.futuremark.com/compare?pcmv=359473
Congrats Computurd,
I've been playing a bit with a few Vertex 2s and I can tell you, without that extra 4GB cache it would take a lot of work and a lot of OC to get to 30'
(possibly a few tweaks as well, are there any known tweaks/guidelines?)
I'm staying at 4GHz for the moment though, still hunting for the optimal stripe size.
Good morning Mr Anvil,
The optimum # of drives changed for me based cpu speed.
4800 - x5 drives
5200 - x7 drives
also pcie max oc droped from 119 to 118
reminder - use only the x64 version of pcmv
whow!!
And there goes Mr CT screaming past Mr Mbreslin to take the #5 position! :up:
Narrowest of leads - CT's 31268 to Mbreslin's 31252 - 16 points! :D
Paul has to be pouring magic sauce into that ancient 920/gen 1 vertex array! :up:
has anyone compared 1231ml vs 1880 with SSDs
also cache size performance scaling
Good the see you found it.Quote:

But there is was a 12V line
I'm planning on doing a 1231 vs 1880 but probably not till next month.Quote:

Mr Dinos, sir - why not YOU do it for us!! :yepp::yepp::yepp:
i would if i had the cards. I borrowed the card from areca and they are asking for it to be sent back....
i also dont have any 4GB sticks nor do i have the 1880 card to compare
Maybe areca would let you borrow both a 1231 and an 1880 and you could do a nice write up for them?
i dont know it went through HQ so i dont know what those people discuss but i would certainly love to do that. Ive spent a lot of time on it already. This storage business is very addictive :D ... so has my mate James :D
Yes, very time consuming!
There are so many tweakable variables and the veriables interact - trying to find optimum is sometimes more an art than a science.
Some other 1880 fun..
16xhitachi 2tb raid-0 :p:
I going to test performance @ raid-5 and raid-6. I have to have something to fill up the ports on the controller :D
And 4gb cache test soon ;)
This 920 is rockin until the SB 2011 socket is out...:up:Quote:

was wondering when you would bite!Quote:

@nizzen..jesus that is a ton of devices! would be fun to play with :)
how long until you get your 4gb and come to kill me?:)
UPS is killing me :p:Quote:

I do not know what the spike is, but who cares :rolleyes:
good gives me time to get set for my final trick..the coup de grace...never used it with the 1880, works with 1680&1231 (hint , they have something the 9260 doesnt)(and not cache!), but didnt work with the 9260 OR 9211...the last trick in my hat (once i am in optimal setup)...good for some serious points...:cool:
@ Mr. Nizzen - the very nice huge 2500+ MB/s spike on hd tune writes is most likely your cache - when you go to the 4GB it should probably be same huge speed and last longer (a "wider") spike. :)
Alright Mr. CT! - will you take down Mr Planet?
That will be most impressive if you do - that's another - almost - 1700 points. :shocked:
edit - sounds like you're both happy with your areca purchase so far? ;)
I am leaving the wife....running off with 1880!
If you keep the 1880 powered up it can even keep you warm at night :ROTF:
VERY warm!!
Which is the right 4GB-module? Minimum DDR2-800 (PC-6400)???

@ Computurd
Please shot a pic from the module-label (ram-timings)
there are only two known sticks that work at 800 mhz and they are--
(i have been through three sticks that were incompatible so there is no wiggle room here)
KVR800D2D8P6/4G kingston
UG51T7200N8DR-8CC unigen. to my knowledge not publicly available yet.
these are the onlly two that will work. this is per areca tech support. i am using unigen. i have a 2g of the kingston, but havent used it.
there are many that will work with 2 gb
410€ or US-$ 525 :eek: http://geizhals.at/deutschland/a363721.htmlQuote:

same thing i said. multiple times. thats why i kept buying and they kept not working.
The spec is:
512M x 72-bit 4GB (4096MB) DDR2-800 CL6 SDRAM
(Synchronous DRAM) "dual rank" Registered w/Parity memory module. The
components on
this module include eighteen 256M x 8-bit DDR2-800 SDRAM in FBGA packages.
This 240-
pin DIMM uses gold contact fingers and requires +1.8V
it MUST be x8 or x16... (18 IC only is what is making it hard to find a
replacement.)
