32m SPi Low Clock Challenge

[hipro5]

Here's a sub 11 min when I was warming up my CPU after LN2 benching....
Not a well tweaked run and these Windows are my 3D windows.....

[Zeus]

Wow buddy, that's blistering fast!!

[ToyTen]

well, that's like Zeus said


Did you putted that much Vcore on purpose to speed up the cpu ? or was it just a need for anyreason ?

[hipro5]

No, I just left the VCore as is for warming up the CPU after the LN2 benching...No particular reason for that...

[George_o/c]

George great work man Care to share your CW file size with us (we already know your way of CW , unless you have changed it), even with a PM ?

And ToyTen thanks a lot for your tip
Hope that my advice helped you a bit

Nah for some people it's really easy

[BenchZowner]

tRRD ain't hard, at least with most D9GTRs.
tWTR is relatively tight up there, George is probably using strikingly high voltages again
tRAS 15 is quite good, only a few kits can do 32m at DDR3-1950+ at these timings.

[Zeus]

Altough these subtimings are tight as can be, it gains very little in 32M from my own experience.

And, like said, it will take some volts to get there, not eveyone is brave enough to exceed 2,2V on DDR3.

But yes, it sure looks cool!

Nice one

Hi to all, I hope to get something into 9.xx soon...

Many thanks guys for the tips in the thread and to monteboy for SpiTweaker -
so far helped me lose about 8-9 seconds from my untweaked times for 599x7.5

Memory is 2x1 CS3222271 800mhz (D9JNL), and not good with vDIMM higher than 1.90V (set). Using 2.01V here.

I also used:

XP32 SP2, maxmem 600, large system cache, page file disabled, core 0 affinity,
realtime priority, 1 hard disk (2 partition), SPiTweaker 1.0 as shown.





I included this failed run (with a few tighter sub-timings) as it's 1.5s
ahead of the other 599x7.5 run at Loop 21. No finish yet though.

Nice run Keep 'em coming

A couple tips though I suppose that C is your SuperPi partition ... on that one keep the page file at stock value Set the page file in your empty partition (apparently E) 384-384 or 512-512 ... Try using CW file size 1024MB, or 1896MB, from C to E (from SPi partition to empty partition)

Also try Maxmem = 640MB, it should work for you better

Today I tried some CW file sizes, at around 1.3GB, and for sure had some nice results ... 'Still gotta test more though, so that I'm ready before I report back again ...

@kemo Your run is TOO slow man ... Something's weird going on there ... Why is your E8400 running with only 1 core enabled ?

With no tweaking at all you should get into 12.59.xxx category with less than 3400MHz ... A well tweaked run @ 3600MHz is about 12m ...

[hipro5]

Hmmmmmm..........NO e-mail notifications again.......

I used 3072GB sharp (1024x3)...

.........and I ALWAYS work with 2.25VDimm in my rams....

Thank you George_o/c - and I will follow your advice....

I have been running Spi from the second partition as it seemed faster, and for some reason more consistent with Loop times.
When I run Spi from the C partition, initial values are 0.5s faster, but alternate loops run slower/faster, and always finish slower*
Something else not right perhaps ?

(EDIT 07 Jan: *not always slower - added new screenshot below)

Despite my current CW/partition setup, I hope that 597-8*7.5, with the tighter memory timings,
will be fast/stable enough to get 9.59.x



something else which might be of interest: 500x9/1:2/CL8, with CL8/tRD6 running on 200 strap

Not so close as my 599x7.5, but not too slow for CL8 on an Intel chipset.

Don't know if 9.xx is achievable for me at 500x9/CL8 - another 3 seconds is quite long,
and this time is already 10-12 seconds faster than my untweaked time.




I can't go lower than these timings so far, though trying tRAS 12 instead of 16 worked ok
(tRAS 8 booted from BIOS but killed performance).
Not sure how much tRAS 12 is the reason for the faster run but no slow down as with tRAS 8.
I will try 8-8-6-12 next time.



EDIT 07 Jan:

Might not be a direct comparison as now back on 0403, but this run was correctly using 'C' as SuperPi partition.
However, SPiTweaker settings still same as above; i.e. Spi partition now 'incorrectly' set as 'D' and empty as 'C'.
Quite hopeful now for this clock to hit 9.xx (just a personal goal) - will now try Tweaker / maxmem settings as George_o/c suggests.....

BTW, cannot run 8-8-6-12 - fails before initial value at any vDIMM.

I think I can reach sub 9mn with 3905-3910 by lowering CPU ratio and increasing the rest . Despite it, it should be possible with 3880-3860MHz under cold to fix Uncore near 4600MHz

Nop , it is not slow at all , i am using 2X2GB PC6400 CL6 kit that retails for less than 50$ , that is the highest memory clock i could get , try running @500mhz 5-5-5-15 and you will see what i mean and for that Single core it comes from a special XP (92MB total) version that shaved me 16s from my regular SP3 , but it has no paint no Print screen and many other essentials messing , if i can get a 600MHZ 4-4-4 kit i am pretty sure that i will shave more than 50 Seconds
Here is my Un-tweaked run with regular 24/7 XP SP3 (13:41)

(sorry for the double post)

after posting my 9m59.391 run, I found this.....


http://www.xtremesystems.org/forums/...&postcount=152


3oh6's finish time and checksum are the same.


I have two other 9m59.x runs at the same CPU clock - should I post one of those too ?

Thanks for any advice

Hi guys,

I'm benching my i7 and trying to do sub10 and sub9...I'm working on sub10 actually, but i have no idea of what's good. Any help ?
I have only 2x1 Go, but i think my resulsts are not too bad, i'll try with 3x1 Go this week end :p

Thx

Hi everybody .
This is my first post on this tread . I want just compared for my first test . I'm working on tweaks . Size of CW , swap ( or no ) and maxmem .

- XP 32 SP3 lighted by me
- pi.exe on C: ( hdd windows )
- CW file of 3Go copy C:>D: , D is an other disk
- Swap of 512/512 on D:
