Sub 4GHz SPi 1M

[quake6]

Is it possible to go below 11.550s with sub 4GHz in 1M super pi? I run it at 470*8.5 with 7-6-5 1880MHz DC and just cant go below 11.560s... What is you result?

[jas420221]

I was 11.4xx with a 3.9Ghz quad (488Mhz), and 4-3-3-12 timings..let me dig up the SS

[makaka]

sub 4 GHz ?? do u mean for 3999 Mhz ? or how much exactly , i can do some test

[ceemic]

There's nothing hard about that.
Lets take "performance points" for reference (spi1M time x CPU MHz).
I'll point out that Super Pi "performance" depends on OS(XP usually faster than Vista etc); ram speed/timings; FSB; services/programs/processes etc; chipset; HDD etc.

A "normal" 24/7 45nm+DDR2@CL4 system does ~46500pp. When we want 11,549sec, then 46500:11,549=4026MHz
A little bit "lited" XP with less background processed does below 46000pp (my P35+E8500+DDR2@CL4 did 45800pp 24/7).
Example: 45900:11,549=3974MHz
Well-tweaked systems can do even below 45000pp (high-end extreme tweakers can do even below 44000pp). That means fresh OS (usually lited), only essential services + "OS tweaks", real tight ram timings etc etc etc.
Example: 44500:11,549=3853MHz

Commonly DDR3 is a little bit slower in 24/7 spi1M (because of timings). I'd say around ~47000pp or worse.
Example: 47100:11,549=4078MHz

It's simple math :) Just multiply Your CPU MHz with time so You'll see how Your system performs.
7-6-5 1880MHz DDR3 for 24/7 is really good and should do below 46500pp easily. If it can't, then You'll have to look whats "bottle-necking" Your system. Probably old OS, full of "crap" etc. You can see a little boost when You close all "unnecessary" processes in TaskManager, set affinity to one core and use RealTime ;)
PS. What motherboard are You using?
Good luck!

[quake6]

I run it at diagnostic mode,set affinity to cpu 1,and SP to realtime... Fresh install of windows XP SP1,no drivers for chipset,gpu...

I'm using black ops with gts memory chips
Timings was 7-6-5-15-52,Performance level was 6,twr 20,twtr 16,trrd 5,trtp 5...

And when I'm asking,is this good score?

Just serving a super light XP with almost "0" background activity helps a lot...

(XP+nLite/142MB CD)

[quake6]

Where can I find that super light XP :D
Do you have image?

[ceemic]

quake6, that's almost OK, tho I would have quessed with these timings and "tweaks" it performs below 46000pp.
Try to boot with 398FSB and use SetFSB in win to go the same clock :P

[ceemic]

I use 183MB XP install CD for benching in 36GB Raptor :D The memory usage is 26MB and only 1 service running :D
I can help You with that: PM ;)

[quake6]

I just dont know where I'm making mistakes for SUB 4ghz... Sub timings are also quite tight,memory is working at 2.3v and that is enough for very tight sub tim.,and in task manager I turn everything that I can,I have only 6 (i think it is 6) process in it

[TheGanG]

Where can I find that super light XP :D
Do you have image?


Yeah homebrew, but it's illegal to make copies :D

u better download nLite and some manuals to create a light XP image...

[KanGaXx]

ddr2 perform better than ddr3 at spi1mb...
if you try 8mb or 16 or 32 ddr3 own!

[quake6]

And how did you achieve that? :D
Ok,I got 11.547s,for now... Stay tuned:p:

[ceemic]

Also note, that spii1M efficiency depend on motherboard manufacturer also ;)
Usually Gigabyte<Asus<DFI with same chipset.

[quake6]

Here are my settings...

[jmax_oc]

11,2xx @ 4GHz is very doable with any Intel chipset and prepenryn BIOS ;)

[quake6]

And could somebody say where I'm mistaking? I did nlite XP,fresh install again and it's the same...

[makaka]

u may try a some lower memory timing . this may help . As said above DDR3 is not good for 1MB but if u try 32mb 16 or even 8 mb your result will be far better

[quake6]

@makaka: I just cant go lower then that...
@redratamd: nice score ;)

[TheGanG]

11,2xx @ 4GHz is very doable with any Intel chipset and prepenryn BIOS ;)

Yeah, "unknown CPU" makes a good job...

[quake6]

These are my results...

I have to take of 7s for 32m... I use maxmem 512,no PF,waza size 480mb,single file size 128kb and no CDT...

[quake6]

Okay...After 2 all day benching,I've finally manage to get this :)

[ewitte]

At 3.8Ghz, my 24/7, I'm around 12.3-12.4 but thats with PC6400 ram and auto timings.

[Bullet92]

Be free to post your setup here ;)

[AndrewZorn]

What am I doing wrong?

3.8ghz
1012mhz, 5-5-5-15 (I know, not the best, read on)

XP 32bit
8 processes not including superpi (only two less than usual, ended explorer)
2 services total (usually i run 4 (including Themes!), these last two: RPC, PnP cannot be disabled)
Tried setting affinity, changing priority... doesn't seem to do much.

Still can't get under 13seconds. About 13.2xx every time.

Is it some 'strap' thing?

[Revv23]

Whats the rest of your setup? performance level? mobo?

[AndrewZorn]

It's all in the sig...

No problem but try to play more with strap tweaker ;)

I've got 11.218s (http://http://pce.hostili.com/images/sub4hc4fdd.jpg) and will try to get less soon. It was with good old P5K ;)

Bullet92, I still haven't got time to try strap-tweaker :(

[yankee]

Your settings considered, particularly ram timings, your time doesn't seem too bad. Also, it's a conroe G0, so it's just not as efficient as a wolfdale or bloomfield.

You could probably get a few tenths shaved off by upping your Performance Level. It can be a pain to get stable though.

Edit: I did bench a G0 conroe at nearly the same settings. (http://www.hwbot.org/result.do?resultId=745376)

Read this thread and then post your result...

[MrMason]

I hit around 10.2-10.3 at 3.998ghz on my i7 920

[quake6]

Come on guys,read this thread before posting... This isn't for Nehalem...

[okorop]

sorry i did'not know it.....:) I remove my screen shot now

[xcavax]

nice score okorop! :)

[tool_462]

Come on guys,read this thread before posting... This isn't for Nehalem...

Did it say that anywhere? I must've missed it.

Either way here is my result:

I could've sworn I had a 11.250 run with DDR2-1000 CAS 3 but I can't find a screenshot anywhere. I may be wrong though.

This is a new benchmark for me, and my times are terrible:

http://i650.photobucket.com/albums/uu225/AceNZ/pi.jpg

I ran the test with affinity set to one CPU and in realtime mode. My OS is Windows Vista Ultimate 32-bit.

Could the poor result be happening due to the 4MB of cache per CPU, vs. 6MB for some of the better results?

I do have a bunch of services running, but it's hard to imagine that being more than a 20% effect at the absolute maximum.

I know my memory timings are a little off. I've had trouble getting the numbers where they should be (the chips are spec'd at 5-5-5-15). My motherboard is a Gigabyte GA-P35-DS3P. Again though, this doesn't seem like a big enough difference to account for my results.

I have speedstep enabled, but it kicks up to 2400 MHz after only about 3 seconds. If I disable speedstep, the overall result only improves by about 1 sec.

[proxis]

vista and speedstep is a mistake for superpi
4mb is also slower than 6mb , best you can get with 4mb is somewhere in 50500 pp

[Gaul]

heres mine, no - TWEAK
