32m SPi Low Clock Challenge

[Zeus]

Looks like Bank Interleave is responsible for that boost.

CCC, i take it that post isn't yours since you quoted it but do you know how much difference there is between 2x1GB and 4x1GB?

[CCC]

yeah not mine

Conclusion:
With the higher divider 950 MHz with 2x1024 at loop #4 and 12 with same os settings no copy waza it’s slower at 571x7 than with 4gig at the 913 MHz ram speed divider so with a good copy waza on both I can’t see the 2 sticks winning out

but overall because 4gig is limited on my board on air cooling to about 920mhz 7-6-5-1t, and 8-7-6-18-1t at 940mhz or so before going to 2t I’m sure a properly calibrated 2 stick system will always win out top end, but goes to show what the RE and 4 good sticks can do depending on the fsb+divider+overall MHz your allowed

BTW:
Everest at these settings is 12,900 - 13,025 incase anyone was wondering

8-7-6-1t action at 960mhz/ddr1920.
would be unreal speed if 7-6-6/7-6-5 would run, but considering its 4gig
at 1t its not so bad

Hi guys, i post some scores what i make this week-end

4500Mhz | dami1stm| E8600 7.5X600 | Asus Rampage Extreme |X48 | CellShock PC12800 (D9GTR) 960 7-6-5-15 1T



4000Mhz 10m52.688 | dami1stm| E8600 8X500 | Asus Rampage Extreme |X48 | CellShock PC12800 (D9GTR) 1000 7-6-6-18 1T




3600Mhz 11m49.203 | dami1stm| E8600 6X600 | Asus Rampage Extreme |X48 | CellShock PC12800 (D9GTR) 960 7-6-5-15 1T

Really nice runs! What abaout MAXMEM and CopyWAZA???

Alex

[dami1stm]

Copy waza makes with 3470mb size files between my Raptor 74Go and my second hard drive Seagate 320Go 16mo SATAII. Maxmem was set to 600.

For the 8X500 DRAM 1:2, i use 266 strap with performance level 6 direct from the boot and the Ai Clock Twister set to strong. For this, i most set 1.84vNB to finish the superPi32M

I think i can reach 10.51s for 4Ghz frequency if i can set PL7 with 7X572 DRAM 900 settings (i have made 10.54.540s with this settings and PL8) or if i can use 4GB of memory. So, i need some cold on my Northbridge and 2 more sticks of RAM

[Delex]

Thank you very much for the info! I tried with 3470mb file and maxmem 580-600-620 paging 512-512 but no gain....only 4 seconds boost with Copy Waza. How much did you get with CW?

Tnx

Hi guys, i post some scores what i make this week-end

Fast...

[dami1stm]

I win around 3~4s with CW, and around 0.7s with maxmem set to 600

The good maxmem value depends of your OS. I use Windows XP Pro 32Bits tweaked by me (I give a name to this OS: Extreme-OC-OS ) also it's always the same value for all SuperPi 32M

You can actived the "largesystemcache" key also (regedit), and kill one big parts of "services", like "spooler.exe, the greatest svhost, and the explorer.exe also. You can reduce the Window of SuperPi to win 0.2s also.

I clock all the time with no svhost and explorer.exe service, it's make better scores and stability.

When i launch the superPi, the system pagnition weighs only 44Mbs

I set the priority to "core1" and realtime time mode.

[Delex]

Ok thank you! 3-4", the same lik mine scores...somebody told me that it's possible to get 7-8 and 12 seconds on 4 GHZ :S, I don't know...I have about 8-10Mb difference between Cahce and mem after waza...Wha do yo uahve (Gautam and dai1stm)??

Tnx

Alex

[dami1stm]

Fast...

Thx

I'm so impatient to have some cold for the E8600. 6Ghz spi32 to begins

[ToyTen]

congrats Dam, very motivating

[Harshal]

Yes indeed that time is FAST, dami1stm!!
Don't have a real good set of DDR3 ram but will try my best and get back now that I have a RE.. I think its mandatory to post some Pi32M numbers

[dami1stm]

So, I begin the serious things...

[Zeus]

Wow that is just insane! Very very fast!

[Delex]

How is it?

Alex

[I34z1k]

I don't think this deserves it's own thread but for some reason I think my time is not that good :/ I listed most tweaks I used. Priority @ realtime, core1. Defragged a couple times. Quite clean install, not very light tho.

Any tips?

[George_o/c]

@dami1stm: Crazy run man, fast, TOO fast !
@Delex: 10m58s @ 4050Mhz is a great run, considering you are a starter When you have the ability to pull of 10m58s @ 3.95 - 4GHz your tweaking skills will be awesome ! Use Luna theme btw, it's faster for SPi

[ToyTen]

10.xx time zone
4003.5......ToyTen.....10.53.859.....8x500......10 00mhz.....7-6-6-16....1/2...X48



CW home made with one hard disk drive and one partition.
Raptor 74Go (16mo)
file size is 1,91Go not compressed.

[dami1stm]

Nice run Toyten

Try to set the tREF timings to the highest value (16xxx)

Thank you dam1stm I listened to you and there is the result:

3958......ToyTen......10.59.484......494.8x8...... 989.5......1:2......X48

[Zeus]

You really got it going now ToyTen! Very nice results mate!

[ToyTen]

Thank you Zeus

[George_o/c]

Wow Toyten, you are on a roll mister
Crazy fast run !
But you don't play fair, you have some nice piece of memory as your faithfull assistant What brand are they ? How much Vdimm ?

[dami1stm]

As soon as I have finish the tests of Nehalem I am going to start again bench some Superpi 32m.

I aim at the first places or ex-eaquo everywhere ^^

EDIT: At 3556Mhz i make 12.00.015s ^^
