32m Low Clock Challenge

[alpha0ne]

Since some of you guys are still missing the point of this thread, here's a valid submission

Core 2 Duo E6600 @ 402x9=3618Mhz, Corsair 6400C3 @ DDR2-1206 8-4-4-4.0 --> 12:59.922
vdimm: 2.45v (BIOS) --> 2.47v LOAD (DMM)
vcore: 1.48v (BIOS) --> 1.46v LOAD (DMM)
ASUS P5B Deluxe, not yet modded at all
Still on Intel stock cooler

I just barely made it into 12:xx category, which IS the goal to achieve at the LOWEST possible CPU clock.

But its still above 3.60GHz

Finally i fixed my 32M problems, and luckily it fits into the sub 13m category!



No tweaks and 24/7-windows, just realtime.

[sierra_bound]

Tweaking does make a difference.

[funkflix]

Higher memclocks + B2 and which tweak else do u used? This copy-big-file-tweak?

Don't think this new 2x512 GeILs (no D9, as i expected ) i use can do 505MHz, so i will lose the advantage of 2GB, and thats not good..

[sierra_bound]

Yes, copy-big-file-tweak and others. Some people think the P5B Dlx is slow. If you keep FSB in the 400+ range and use 4:5, it's not slow at all.

Hard one with an E6600!

Anyway, i booted with 400MHz and put up the FSB to 450MHz with SetFSB, so it should be the same effect, as if u stay around 400MHz. With this way i got an error first time, with just 1,45V on the NB, needed 1,55V then. When i boot up with 423MHz i can go to 500MHz easy on 1,45V.

But its still above 3.60GHz

Well, it's not the point of this Challenge, if you read carefully. It's the certain time window you need to fit in (9:5x, 10:5x, 11:5x, 12:5x, etc) at the lowest possible CPU clock. not the other way around

Hard one with an E6600!

Yep, things are a bit more difficult with E6600 as in some cases x9 multi is just a tad too low to fully take advantage of tight strap. Even E6700 is a lot better to work with...
A propos, this is pretty much all I can do for "below 12m" category. With E6700/P5B Deluxe, this can could be probably beaten @ 410x10 4:5, though...

Core 2 Duo E6600 @ 465x9=4182Mhz, Corsair 6400C3 @ DDR2-930 4-4-4-4.0 --> 11:58.344
ASUS P5B Deluxe, vcore/vdimm/vmch-modded; CPU cooled w/ "402XTREME" by Chilly1
vcore: 1.68v (DMM)
vdimm: 2.18v (DMM)
vmch: 1.75v (DMM)

Naturally, this result is achieved by booting @ 400x9 and raising FSB to 465MHz using ClockGen...

EDIT: This is just to compare with sierra's and funkflix's results and to show what can be done on P5B Deluxe. Below result is no good for this Challenge...

Core 2 Duo E6600 @ 432x9=3887Mhz, Corsair 6400C3 @ DDR2-1080 5-4-4-5.0 --> 12:36.922
ASUS P5B Deluxe, vcore/vdimm/vmch-modded; CPU cooled w/ "402XTREME" by Chilly1
vcore: 1.72v (DMM)
vdimm: 2.46v (DMM)
vmch: 1.56v (DMM)

Also, system booted @ 400x9 4:5 and then FSB raised to 432 using ClockGen. Ratio 4:5 and "tight strap" were very hard for me to harness at the same time, though. Only going CAS5 allowed me to reach above 410MHz. That 432MHz is all I could do for 32M. Straight boot @ 4:5 was good for 32M all the way up to 450MHz (DDR2-1125)...

Hey bachus, nice work, i love watching you do 32m runs as your scores are always so much better then mine at similar clocks (i dont know much about super pi lol)

Anyways, 4:5 clocking on the 1066 strap is helped a ton by raising up the vmch. I too couldnt pass 410 with clockgen but going up to 1.8v vmch got me alot higher, also a tras from 6-8 may let you keep the cas at 4 for the runs.

Good luck!

If I boot at 8 x 465 with E6600 on P5B deluxe, what bootstrap is this booting with ? and I was under the impression this thread is about low clock speed 32mb times. Whats all this discussion about over 4Ghz clock speed times ? or is 4Ghz considered low clock speed ? ? ?

[Bootup05]

What is this all about

I'd like to have a go but im not sure what were doing

Do you have to tweak whatever you can to get the closest to 24mins at the lowest clocks you can?

[funkflix]

Try to get a time like xx min 59.xx sec and this with the lowest clocks possible. Doesn't matter which clocks u use, only the time is important. Look at the results here and try to beat it, or going for an equal result.

straight boot at 465 = 1333 strap = BAD for Pi

[alpha0ne]

straight boot at 465 = 1333 strap = BAD for Pi

Better with sauce on

[dinos22]

you can always do a vMCH mod

rip off the stock cooler and slap something decent

and boot at sub 400MHz and clockgen up with monster vmch and 1067 stap.......doable past 500MHz and killer PI times

[3oh6]

not sure if the first post is being updated anymore but i had some free time this morning so i decided to have a go with the E6300.

boot @ 399...clockgen up to 462FSB to keep that strap where it belongs. 14.XXX is about the lowest time block i can shoot for with the P5B-Dlx and 7X multi of an E6300. i spent a good couple hours at it and this is the best i could pull:

14m 58.281s @ 3238MHz

[coop]

Yes, it is being updated. Very good time and thanks for your contribution 3oh6. Helluva a good run bachus - as usual. That should stand for some time. I'm working on my board and, if it still boots up, will try to make some contributions as well.

can you share with us the cooling method on MCH including vMCH used and whether you modded it

[3oh6]

Yes, it is being updated. Very good time and thanks for your contribution 3oh6.

excellent and thanx. i will try to get to some AMD times later...i'm too busy playing with my new toy

can you share with us the cooling method on MCH including vMCH used and whether you modded it

can do dinos...this one is un-modded so vMCH is the BIOS max of 1.65v. i have pulled the stock heatpipe setup and slapped a Zalman ZM-NB47J on there that i had laying around. i have a 120mm leaning up against the ultra-120 blowing over the DIMMs and the northbridge.

i can CG up to about 470 and bench pretty much anything there but over that and even 1M gets hit or miss. this is my second P5B-Dlx and the first one would crap out around 460ish (CGing from 399 of course) with the same cooling. this one seems to be better so i think i will be keeping it and the mods should come soon, just waiting on some trimmer pots for the droop and vCORE. with a Maximizer in hand, i won't have to worry about the vDIMM

[dinos22]

damn you 3oh6 and your maximizer

nice motherboard man

searches for that zalman somewhere heheheheh

hehehe, check out my thread i started in Xtreme Bandwidth...i haven't hooked it up to the board yet but i can't stop playing with it. i feel like a 6 year old with a new fire truck on christmas morning...i think the term is "shyt eating grin"

that zalman should be had pretty much anywhere...its bright blue, passive, and just fits under the fins of an Ultra-120 on a P5B-Dlx...and it only cost me $11CDN from my local shop. apparently its pretty decent or i just got lucky with this motherboard. can't wait to see what it will do with a small dry ice pot and the vMCH modded...500FSB/1066 strap here i come

hahahah that was funny

yeah i know those Zalmans did a world of good for me in early 2005 with Asus A8N Deluxe replacement for that POS whinny little fan heheheh..........

[farksy]

I know this is abit late, and abit mediocre ... but .. here's mine. Sub 3Ghz Opty under 24min

2992......farksy.................23.58.671



Way off the rest ... perhaps my OS isnt' right ? [on the Xs stripped down one] and also because this is a 10Gb partition of my 80GB Hdd. Should get those benching harddisks so as to not wreck my files.

[eva2000]

just under 15min @3320Mhz with Intel D975XBX Bad axe rev304
