I been gaining about 40 mhz a day, from Burning In my CPU. 56K Warning...

[Kunaak]

I have a really odd CPU here, a 2.66 ghz prescott, 533 FSB.
it's a great CPU, cause it OC's like crazy.
does 4 ghz on air at default voltages stable.
did 4.46 ghz for a suicide shot on air.
was stable enough to pass benchmarks at 4.3 ghz on air, including 32M in super pi and 3dmark2001se.

well the other day, I finally made a way to adapt my old Dtek Spiral, to fit on my Abit AS8. this is a cheap waterblock by most means, it only cost me $12 on the OC-forums a year ago... no Whitewater for me.
so these results are extremely impressive to me so far.

http://www.xtremesystems.org/forums/attachment.php?attachmentid=26957&stc=1

on water, at first it was doing about 4.54 ghz.
then after 2 days of burning in at 4.1 ghz, at 1.36 volts, I gave a suicide shot another try, and this time it topped at 4.6 ghz even.
so I burned it in most of yesterday, and most of the night before, and this morning I tried a suicide shot again, and now it's doing 4.64 ghz stable for screen shots, and 4.66 ghz no screen shot (which does bug me, cause thats exactly 2 ghz OC, and just one FSB away I can get a shot of it, but 2 ghz OC even, I can't get a screen shot of :( but I am gonna keep trying)

http://www.xtremesystems.org/forums/attachment.php?attachmentid=26958&stc=1

the other day, it was nearly impossible to benchmark past 4.4 ghz, even with watercooling the CPU, and NB.
after 2 days of many hours of burning in, I can benchmark a few things at 4.48 ghz.... or 80 mhz more then I was able to just 3 days ago.

Before:

http://www.xtremesystems.org/forums/attachment.php?attachmentid=26959&stc=1

alll I been doing is burning in my ram and CPU with prime 95, letting it run anytime I go somewhere or want to watch tv or something else.
but the results are really coming through.
this is the first time I ever seen results like this for "Burning In" since my old XP2100, went from 2.8 ghz to 2.85 ghz stable under my prometeia after a week of burning in.... which back then, was extremely cool to see.

After:

anyways, I am not trying to say Burning in will do miracles for you, but in the case of this CPU here, it's clearly doing something, cause I am gaining a few more MHZ everyday, and I think if I let it burn in longer, I might be able to hit 4.7 ghz on water. with alot of luck I mean :D

[jrw]

Burn baby, burn!

I am really curious as to what exactly happens during burn-in? Someone care to explain?

[afireinside]

Very nice :D I've never tried burning stuff in. Maybe I should... Whered you get that chip?

[Major]

Just curious what your using as TIM ??

[Nubius]

I am really curious as to what exactly happens during burn-in? Someone care to explain Simply put, the transistors warm up and expand, and over time, they will be more prone to allow more voltages, or higher clock speeds through them.

[Kunaak]

Just curious what your using as TIM ?? Artic Ceramique. nothing fancy.

[ozzimark]

could it be that your ceramique is setting, lowering the temps, thus allowing for a higer overclock? :toast:

Nice clocks. :toast: You have any sandra benchies?

[Kunaak]

it's possible I suppose, but for me, it would be a definate first.
I have used alot of CPU's and I've never experienced a better overclock 2 weeks later, then I did the first day using the same CPU.
thermal paste settling, just never made a difference for me ever in the past.
it's always been the same.

if I got 2.7 ghz on day one, then I got 2.7 ghz on day 223 too.

this is the first time in a while that I had any sort of signifigant benifit from burning in anything, except when I burn in ram.

[jonspd]

Nice buin-in result's wish I had a amd story similiar.

[Nubius]

Might explain my burn in method :toast:

Well for most OC'ers it's a good common rule of thumb, I know it was when I first learned about OC'ing. My eVGA 6600GT wouldn't like to go above 1GHz memory from 900MHz (agp version) until a week later, then it hit 1.1GHz like butta after that :banana:

[LikwidKool]

nice results Kunaak. I had kinda given up on burining in, until my VX did 5mghz better after I fell asleep when running memtest at 260 3.5v Never could do 265 before that.

Heck that is one nice cpu btw.

OT: Woohoo! 1k posts! Only took 2 1/2 years here. Quality above quantity;)

[enzoR]

Simply put, the transistors warm up and expand, and over time, they will be more prone to allow more voltages, or higher clock speeds through them.

what!? lol its about electromigration where electrons eat away the transistor gates. they also get imbeded in the insulator giving it a slightly negative charge which can help the transistor switch faster. not entirely correct but better than your explanation ;)

[saaya]

nice man! :toast:
what are the load temps on that thing?
cant wait to see what it does with better cooling!
what ambient temps do you have? do you have the rad hanging outside the window?

You gained a 110MHz increase by only burning in, exactly what the hell did you do?!! :eek:

[BlackPearl]

Great results - if you can keep up the pace you should be over 13.0 GHz by Christmas! :)

really nice cpu!!!!

[Kunaak]

nice man! :toast:

load temps at 4.1 ghz at 1.3375 volts is about 48C when under full Prime 95 Load after a few hours.
the CPU isn't really my concern, its the PWM that gets incredibly hot, at about 55C, even with fans cooling that area.
so I orderd some Artic Thermal Paste today, and chopped some heatsinks last night, so when the thermal paste arrives, hopefully I can get it down a few degrees.
but then again, I do run 1.4 volts from the chipset and 1.7 volts for the AGP everyday, so the PWM is alittle hotter then it was at stock.
cooling the area, directly above the CPU socket is essential, cause with watercooling on the CPU, theres no "side air" coming from the heatsink to cool the things around the CPU socket, and that meant my temps were well above 80C... pretty crazy on the AS8.
so CPU temps aren't a big deal yet, it's the PWM thats my biggest concern right now.

Ambient temps are about 65 F in my room.
I can't hang anything out the window, cause unfortunatly my window doesn't open in my bedroom.
I will take a picture of the set up later to show you what my mess looks like ;)

[don_vercetti]

my 1800+ didn't used to do over 1.9ghz, now i can hit 2.5 without trouble. I've always found burning in happens, it happened on my gcard with the core and mem, it happens on my RAM, and now my standard proceedure is to let a new piece of kit run with high voltage normal clocks before overclocking it at all.

thats the only one I did so far.
it's only a 9700 Pro at stock, and I really didn't care what the score was, just wanted to see where it would pass. that was on air.

[IvanAndreevich]

Hm.. why 1.9V AGP? I thought it helps stability @ high FSB, but this isn't a high FSB at all. I think my Winchester would get ~22K with the same card no tweaks as well. You're running BH-5 1:1?

[Kunaak]

some more results.
about 10 hours of burning in at 1.4375 volts.

OMG this is insane - 4.5GHz @ SPI! You should get some better cooling for it [sub-zero outside?]

Kunaak I am very impressed by your little 2.66ghz "Prescott that could" :toast:

I looked at your stock 9700 Pro score, and I know that you weren't trying for points, but what drivers/tweaks are you using? Or, what are stock AIW 9700 Pro clocks? B/c I only get 116fps Nature with my 9700 Pro (325/310) at stock, and you have a very nice ~6fps lead.

Thanks :)

[ZeroHero]

That's really great :D . I must try to burn in my wincheter, would be happy if i even just could get 10mhz more ;) . Anyone who got more overclock from burn in with a wincheter?

I like the part too with 260CFM fan on the southbride too :D

4.76ghz on water is a lot, isn't it?
It will be intresting to see how long burn in will give you more oc on the cpu.

[crotale]

Pretty impressive for a D0.

Mobo? AS8?

[yasoumalaka]

Ok well if you haven't read the other forums I'll tell you here. I've been trying to break free from 3.8Ghz for ever. So I'll run prime95 for like three days straight maybe with a little UT in between and then I'll report back to let you know if it helped me.

[Malachia]

how much time i must run prime 95 to see benefits???

[enroscado]

Hhhmmmm..., i just found Kunaak's little secret!

He's not burning in anything, he's freezing in! :p:

what kind of computer is that. I hope most of us have are puters in cases.

[Bennah]

yup its ice, for his bucket ;) (off note: i saw a huge bag of ice at asda (uk name for walmart) for £0.79p, must of been about 4kg's or so. cheap as hell me thinks, so im gunner get a couple of bags and fill up a large container and fill it with chilled liquid.

some xtreme setup you got going there man. love that huge fan, me needs one of them. i saw zakalwe have one too. i just need to source one.

what liquid you using btw?

[Kunaak]

Hhhmmmm..., i just found Kunaak's little secret!

He's not burning in anything, he's freezing in! :p:

I wish I could tell that was from the CPU, but that was from a week ago, when I was messing with Pelts on my MCW50T. I tried ice in the res for the CPU, and it does nothing but melt in 2 minutes :rolleyes:

[Bennah]

alright the ice might not be a good idea then... maybe one of cooling blocks that you put in the freezer to cool then you put them in a coolbag or coolbox to keep your beer cold ;)

[Kunaak]

if I drank beer I would.

don't think I am not trying to find a way to use cold water or something for my CPU ;)
believe me I tried ice, but it does nothing in a res that size, it just melts in about a minute or two, cause the water is alittle warm from the CPU already.

I do however have a rather funny idea.

I want to see if I can adapt my sink, to my watercooling :D
my water here in alaska is coooooooold, cause it comes straight off the mountain glaciers, and it's barely above freezing, even all year. be fun to try on my CPU.

[IvanAndreevich]

Yeah you'll get a 20 degree CPU temp drop if you do that :)

Any further gains?

[Kunaak]

Any further gains?

nope. I can still get about 4.7 to 4.72 ghz screen shots completly unstable.
4.76 was a fluke almost, cause I am only 2 FSB away from there, but it's not doing it again.
however. I almost passed super PI at 4.6 ghz last night, which is about 6 mhz more then a few days ago, this time, no super fan on the southbridge just a "oh what the hell, lets try it" run.

it's burning in at home right now still at 4 ghz 1.4 volts.
I don't like burning in something and pushing it, when I am not there to monitor it everyonce in awhile, so this is a modest burn in session while I am in class for the rest of the day.
it will burn in for about 9 hours by the time I get home and see it again.
hopefully it doesn't reboot or anything :p:

[CrazyXP1700]

sorry for bringing up a deadish thread but i've got a couple questions...
what psu are you using?
im on a OCZ modstream 520W and i get my cpu at 4.4ghz stable... my cpus nice and cool... and my PWM gets scortching hot with a 80CFM 120mm fan on it... it's up at 65C... i think i might have to upgrade the cooler on the southbridge... it's going to be fun finding something that fits...

my cpu is still nice and cool... and im close to getting screenies at 4.5ghz... but i think my memory is holding me back
but what all are you using to burn the cpu in?

[muzz]

I used to fill up a 35 gallon or so bucket with fresh clean snow(packed fairly tight), and add a little water to that.
Makes a really good reservoir for benching sessions IMO :D

I would think you have plenty of fresh clean snow in Alaska!!
