**Zeus** · 11-02-2007, 09:44 AM

Erm....let me think about that.

Theoratically zero latency (or close to zero, zero latency is impossible) should yield better results.

Was the pagefile on the iRAM as well?

It was in and it was out in different testings....

i've tested the CDT lastnight and it was nothing diffrent with CW
E6600 @ 7x514 on Biostar P35 1:1 CL4-4-4-4

No tweak = 13m 18s
CW = 13m 11s
CDT= 13m 11s

This does work (PF & Pi.exe in i-Ram) on a P4...it's not good on C2D.

**Dumo** · 11-02-2007, 09:46 PM

My deepest symphaty KTE.

**dinos22** · 11-02-2007, 09:56 PM

omg KTE i feel your pain man

the best thing to do is not sit around thinking about
THINKING=BAD atm
just get yourself busy for now and all the best. Remember you are not the only one hurting in the world....there are and have been many harder things people have endured....believe me i have

you'll be ok

**dduckquack** · 11-02-2007, 10:19 PM

sheesh just read about the accident, sorry about your loss man, never easy, i know

**Zeus** · 11-03-2007, 12:33 AM

Can you guys get this done?

**andre X_X** · 11-03-2007, 12:40 AM

i've tested it before, i have similar amount between system cache and available memory.. no gain from CDT IV with copy wazza. both of them have similar result.

**G H Z** · 11-03-2007, 01:30 AM

Damn sorry to hear that KTE...

**~~spainis~~** · 11-03-2007, 02:14 AM

Sorry KTE

But anyone know why KTE at startup gets that explorer commits more than 40Mb?

**KTE** · 11-03-2007, 02:40 AM

It's OK. Thanks everyone, very appreciated and comforting when a mountain suddenly falls on you. Nice to know we're humans at the end of the day and someone you didn't know but interact with over a network still retains some humanity and care.

No C2D. In fact what I'll most likely be getting won't be till next Sunday now (I have to go away 4 days (funeral) then come back to an aunts for 2 days then drive to meet my uncle 7 hours away from there (who'll give me the parts as he has them)). It's looking like an E6750 now, Zalman CNPS9700, with Gigabyte P965 DS3, a Samsung Syncmaster TFT, Corsair XMS2 PC-6400 C4 dual channel kit (black heatspreaders), an X800 GT or a 2600 XT, 2x Western Digital 80GB Caviars and a Seasonic S12 650W. They won't be mine though, I'm not paying a dime, they're his and I have to return them soon after in working condition.

That's something I'm stuck on for a long time with Microsoft. Their explorer.exe gives me over a million page faults over an hour or two of running.

I did some testing with 1M on the P4 Celeron. I expected a second or two at most. Findings are very good and consistent. I've noticed the pattern too and tested to see how it works. Look at my above old 1M best time. I'll post my new ones soon.

My Prediction:
I "predict" the guys who are getting ~500/500 (balanced) on a C2D won't see any more gains. Not higher than 500, not lower, balanced. That's the sweetspot with the P4Celeron anyway. Any higher gets higher time, any lower gets higher time too. But I'll test it soon to see for myself.

Not that good... E6750 has a x8 max multiplier [and wall ~500 probably, so no 514x7] and Giga i965 has "strap" >400 or so, with 450x8 the result will be absolutely non-comparable to other [like 9x400 with any board or 514x7 with P35 / X38 / QuadGT / DFI Inf 965] 3,6GHz runs... SetFSB may help [boot @ 400, in Windows => 450, x8] but I still will be 450 1:1. But it will of course let us see a real gain with Conroe.

**KeZzZu** · 11-03-2007, 04:44 AM

Hi my experimets without copywaza and cdt, later doing with them.

Celeron 440@2.3ghz
Abit ip35-E
OCZ Reaper 6400 2x1g
40gb sata hardisk
Vista 32 bit without any updates on it.

Untweaked vista

Tweaked somemore on normal mode.

Safe Mode some tweaks but no mem tweaks becose it wont launch memset on safemode, also it doesnt launch cpu-z got errors only.

Well another thing: Got 0.050 secs off from that safemode run but vista self booted just before screenshot

I realize JMKS. I have no other option TBH, other than that I can't test a C2D setup now and someone else would have to do it instead. If you don't want me to run tests on that for whatever reason then I'd like to be told now please rather than finding out later.

While you have a factual point for "absolute time comparisons across platforms" here you are making the one same mistake. Let me make it clear again:

I am not testing absolute performance or my best time! We are testing the gain CDT can provide. People wanted to see that. P4C showed gains beyond reach. SO now they want to see a C2D do it because they compete with that. Pretty simple really. All you need for that is:

A. Stock best time (same all tweaks with same OS/hardware settings)
B. CW best time (same all tweaks with same OS/hardware settings AND CW done)
C. CDT best time (same all tweaks with same OS/hardware settings AND CDT done)

A - B = CW effect

A - C = CDT effect

I am only helping to see if I can replicate the gain I can get on a P4C. I am NOT a SPi competitor, you should know that by counting how many times I've submitted a SPi result or even tried for one and showed it off on XS before 2-3 days ago.

*I was after the E6850 but he said its needed elsewhere so the second best option was a retail E6750 (unopened yet).
*Can still get a X38/P35/680i/650i board but I see no point. Then it'd start becoming a competition which is not the reason I'm involved for neither do I have hours to spend messing and tweaking with it. I don't spend much time indoors, I have sporting commitments and work 7 days a week and study 5 days for a PhD too.
*I can get an E6600 B2 as well but it doesn't do plus 400FSB air and thats just booting. 1M/32M stable would be less.
*The board can do 520FSB air and they've used it for 4 days.
*If cooling becomes a problem and I get a really sucky chip I'll throw everything into a -20C freezer (a tried and tested method

).
Hope its not a dud though.

Quick SPi 1M

Ever do a really fast run and you're getting happy that it's broken your PB but then you get

NOT EXACT ROUND ?

I think we all have had it some time or another.
I get it on the P4C at or above 3553MHz (needs volts which I can't change), definitely if the initial value is at or below 0.681s. There's hardly a run complete at that speed unless its a little slower than the best time. Keep this in mind very firmly.

Results

Best times till yesterday:

STOCK - Standard Windows - 1GB pagefile - 1GB RAM - +35 processes running in background - +25 services running - 1x CDT quick run

3360MHz - 2x 512MB - DDR400 - 2-3-3-6 (660MB memory-670MB cache) = 44.504s
3495MHz - 2x 512MB - DDR416 - 2-3-3-6 (645MB memory-667MB cache) = 42.671s

CDT gives the system an extra 500MHz.

Can I break 40s with OS tweaks?

**~~Onepagebook~~** · 11-04-2007, 09:05 AM

KTE, thanks for your hard work, much appreciate
if you have time, try this,
use the lower full speed of your CPU is going to run
get the pre-cdt job done(while you reach the available/S.C. balanced)
either use setfsb or clockgen, pull all the way to the speed that you desire to run(ex: from 400x9 to 425x9) and then start the super pi; wait for 2nd or 3rd loop finish, directly press the x to close spi windows and start the super pi, run twice of 1m and start 32m, then check the 32m 's available...you will know what is gonna happened.

**T_M** · 11-04-2007, 09:35 AM

*puts on lab coat*

Here's some testing i spent all day doing:

1. Set up OS maxmem=600, pagefile=515~512 and registry large system cache etc. Set WIndows to run in Diagnostic Mode.

2. Set up CDT-IV folders and files. I created the files using 1024x1024x632=662700030. Didnt have enough room on the OS partition, so ran all test copying the files between the SuperPI partition and a data partition. Rar the 3 CDT files into a single uncompressed .rar of size 1.85Gb.

3. Reboot, let idle a while and check taskmanager (picture below). Then perform the CDT copying of .rar file from SuperPI partition to other partition 3 times (rest inbetween each until available memory settles), each time renaming the .rar so i dont replace files. After CDT check task manager again and see 5xxxxx / 5xxxxx .

4. Run 3 CDT tweaked SuperPI (reboot between each) and compare to 3 pre-tweaked runs i did earlier (no reboot between each)

Untweaked:
1. 14m 37.078s
2. 14m 36.188s
3. 14m 35.797s

CDT-IV:
1. 14m 27.985s (think this run was not done properly)
2. 14m 27.891s
3. 14m 27.922s

Compare then to Hipro5's 4Gb "CW" (i dont know how to do proper CW so just did a 4Gb.rar file from a partition to the SuperPI partition.

1. 14m 28.094s
2. 14m 28.109s
3. 14m 27.859s fastest run of the day

6. Graph all results and analyse loop times (time that each loop took). Find that both CDT and CW gave exactly the same characteristics.

OPB, can you please give me some pointers on anything in the above that would cause CDT to not give a better boost than just copying across a single large random file.
I even tried "balance method" where after doing CDT out of the SuperPI folder, i then returned all 3 files back into the SuperPI folder and my time was 1s slower, although both my Available and System Cache were higher (but balanced).

Thanks Kev. I'll try it with the P4/P4C/C2D setup soon. A little far away from a computer at the moment (using laptop).

Good testing T_M.
-When you copy the same RAR 3 times to a partition (x3), you can overwrite it.
-Did you copy the RAR file from i) SPi partition->Another partition ii) SPi partition->another folder on that partition and from iii) Another partition in i) to SPi folder partition?

Your system cache was really low and unbalanced. Those won't be your best results.

**T_M** · 11-04-2007, 10:05 AM

The screenshot of my task manager was before CDT. After CDT it was 5xxxxx / 5xxxxx always. I have photos of them all but cant be bother downloading them.
I was copying from SuperPI partition to another partition on same HDD.

All of the above was already written in my first post .....

your way to do CDT is completely WRONG;

OK, since you are the author of tweak maybe you will be willing to answer a few questions

1. Is CDT described here correct?
2. Is it full tweak or only 60% as someone mentioned here?
3. Should we see better results than CW if it is only 60%?
4. Should it be working on XP or is this specific to 2k3?
5. Any special registry tweaks without which CDT won't work as good?

Thanks, but that doesnt really help me.
I have tried my best to understand the instructions from the broken english post in the first page.
Can you help me more constructively by saying what exactly is wrong with it?
I have put in a lot of time yesterday trying to get this working.

Maybe i should put some of my doubts down as quesitons in point form and you could indulge me with answers:

1. Does the Rar'ing of the files need to be done prior to the SPI run as part of the tweak process (rather than pre-preparing a Rar file).
2. Does the Rar need to be always copied from the SuperPI partition to the OS perition (or will any other parition do as was my case).
3. to be continued...
