DDR3 1000MHz 32M @ 4GHz competition !!!

[camouflage]

:D Cause the 1000MHz club thread got a bit boring now I think it's time to compare our 32M results.

RULES: Only post Your 32M @ 1000MHz @ 4GHz here - tell us what board, chipset, RAM, CPU and what cooling on the RAM You are using.

If You use tweaks You have to tell it in Your post (copywaza, maxmem, large cache, etc.)

Do not post any other SP results, RAM or CPU speeds !!!

I'll make the start:

Board: Maximus Extreme

Chipset: X38

RAM: Cellshock DDR3-1866

CPU: E8500

Cooling on RAM: Air

32M not tweaked !!!

Well....
Making a toplist? :p:
I might join up once I have a little spare time... But 4ghz...? Are we running passive cooling? 4.5ghz is easy with air.... 4.75ghz would be the very best, and yet allow everybody to throw in a try....

;) Not everyone has a chip running 4.5 or 4.75.........;)

beier
these threads are about efficiency rather than max clocks lol

nice time mate
i'll try join in with my 790i and x48t-dq6 when i do some testing soon :up:

[M.Beier]

dino, I know I know, but yet, its more fun with higher clocks... :D Not as much waiting while runing... :p:

[kiwi]

Will join but I am looking at sub 11min at least :)

:D Only possible with copywaza..........;)

[M.Beier]

:D Only possible with copywaza..........;)

Kiwi will use CDT, Im sure... :)
But no, possible without... CL 6-6-5-12 or might even CL 7-6-5-12 should be effecient... I just need a mobo, then I'll give it a shot... Mobo is on its way...

:D For You sure - with ghetto dry ice @ 6-6-5-X..............:p:

i think you can do better my friend ;)

have a look at the CPU i'm using, FSB and RAM speed/timings

:clap: Nice ! Sadly my ME hates everything with 7...... - 7-7-7-x no go, 8-7-7-x no go, 8-8-7-x no go.........:( - only 8-8-8-x is working fine, but I can play with the subtimings;)

[littleBoy]

[dinos22]

you should not limit the competition too much

that RAM and RAM frequency is almost impossible to get unless you have a 790i board

not many MCHs can handle such speeds on Intel plaform

open it up to 4GHz 32M SuperPi comp on any platform (well exclude Nehalem maybe hahah :eek:)

[jmax_oc]

I made 11mn07s but this 11mn01 is really impressive !

7.5x534 RAM 853 6-6-5-15 1T ultra tight timings.
XP Pro SP1 with heavy tweaks

[kiwi]

Dinos is right, only good Intel mch will handle 1000Mhz dual channel.

Have a look at this (http://images.people.overclockers.ru/148252.png) :)

:D Hey guys - keep cool. Sure this is not possible for everybody - but it's like in the Formula 1, not many PPL can start to race there..........:p:

PL = 6 is very good ;). I can't go below PL = 7 for this 32M. What was your CAS6 frequency ?

[dinos22]

PL-6 at 500MHz can be achieved if you run tight RAM timings on 266MHz strap (at least CAS7 (which is really hard on RAM)) or lower RAM ratio and CAS6

it should work

nice time kiwi :)

i've actually done a couple of runs at 3980MHz getting 11m02s which is what my goal was ...to get to sub-11m under Jody's time

with CAS7 i would 100% beat it easy...............with CAS7 and PL6 >> it would be around 10m 50s at 4Ghz and probably around 3950 for sub 11m

thats a quite impressive run :)
PL:6 gives very good performance, I can second that !

http://billedeupload.dk/showpic-2119.jpg
Not 4000mhz CPU, heh... Not tweaked, just wanted a fast result, will announce further info once below 8min 30sec
2.2v vdimm :up:

405x13.5 correct?
if untweaked and you think you can actually do 8m 30s than it's definitely 13.5x multiplier
possible 13xmulti if is what i think actually but i don't know how easy it will be to hit that time though ;)

[jmax_oc]

Yep I know to go and do some benches with PL6 but I don't manage to achieve a complete 32M run :(.
Look at this : http://www.jmax-hardware.com/ftpjmax_oc/BandePassante/13014.JPG

Impossible to be stable at 1GHz with P5E3 WS. Too tight chipset timings ;)

[dinos22]

maybe your RAM cannot do those timings :shrug:
try to use 7-6-6-x or 7-7-7-x timings and see what happens

[M.Beier]

Hmm, I wont confirm/denie anything regarding multi, however, its X38, 1:2, so 455FSB
Reason for 8min 30s is there's hundreds of mhz's left in CPU, atleast thats my belives... :)

Wont announce what freq before the upcoming weekend :)

EDIT:
And trfc can go down by another 30...! ras to cas maybe to 5... 960mhz 6-5-5-12 PL6 would do very good :)

EDIT2:
Jmax, vdimm? Its quite aggressive for 32M !!! Especially if you compare with the "review" threads in this section...

:banana::banana::banana::banana:
my brain is not engaged
i thought i saw 811MHz on RAM
911MHz on RAM is delicious wow :D

in that case we are looking at 11.5x multi

i would be shocked if you told me you pulled this off at 11x multi :shocked::shocked::shocked::shocked::shocked:
actually...

don't know if it is possible unless you are able to run 200MHz strap with PL-5 hehehehe and 6-5-5-15 and extremely tight tRFC, Write to Precharge and tWTR hehehe >> you do that and you will get this sub-9m @ sub 5GHz lol

[jmax_oc]

11mn01s400ms with full optimisations : 7x572MHz RAM 915 7-6-5-15 1T.
Chipset under chiller (-15°C). My problem is that with this BIOS, PL7 isn't stable over 500MHz FSB and PL6 over 400MHz :(.

I have to upgrade it and try to get sub 11mn ;)

[kiwi]

3:5 which is only 833Mhz :) 200 strap, pl6. I don't wanna go offtopic but Blitz Extreme (ME and many other asus boards too) doesn't like certain strap/ram divisors and it limits your PL. For example, 5:8 I cant run PL6 @ 500fsb

I'm a little late on this, but that's very true. In some cases I couldn't run PL Disbaled 6 but I could run Enabled 6 with all settings the same. Now that doesn't make sense. I wish they would disclose more information about what roles PL and STRAP really play. I know that the straps are pretty well documented but as for PL. I don't even know what does. Nor do I know what clock twister actually does.

Sorry for hijack - Once I'm finished with my NB cooler/chiller, I'll participate. Although I need to upgrade my RAM for that. I was going to order up the SST DDR2000 sticks. Anyone running them?
