~Intel Core i3/i5 32nm Dual Core OverCLARKing Thread~

[radaja]

Wy are the posts here so friggin wide?

because people keep posting giant pictures or pictures side by side instead of above each other

[radaja]

my new one is here and its got a lower vid than my last
this one is batch # 3936B105 vid is 1.14v.will post some results soon

[PiLsY]

Why do you think lower vid is better? Silicon is not binned like that, its binned on temperature under load, therefore higher vid means better quality silicon.

My high vid chips have always clocked better than same batch low vid.

Batch is as always most important though. I'll take a low vid good batch over a high vid average or bad any day.

1. i5 660 on maximus III formula L937B897 12/02/09 @ 5266.9 D.ICE http://hwbot.org/community/submissio...660_5266.9_mhz



2. I3 540 I HAVE 2 540 SAME DATE AND BATCH L939B694 12/15/09 (THIS IS THE 1ST ONE) @ 4836
COLD AIR ON STOCK INTEL COOLER ON TH55XE http://hwbot.org/community/submissio...40_4836.23_mhz
Spi 1M http://hwbot.org/community/submissio...540_8sec_750ms


3. 2ND I3 540 also L939B694 12/15/09 on GA H55M-USB3 ln2 @5014 http://hwbot.org/community/submissio...540_5014.5_mhz
my 1st vantage bench on 5850 on air. cpu is on ln2 / http://hwbot.org/listResults.do?user...plicationId=17

mostly all vid for these benches were around 1.25 - 1.35

my favorite boards for clarks I would say the maximus III formula for very easy to understand bios and ram clocking/ high qpi.
and for budget boards under $100.00 its either biostar th55xe or H55m-usb3
I also liked the biostar tpower i55 but I killed mine a little early due to heavy condensation.

4. I have a pentium clark G6950 I need to bench still. Its 12/01/09 - batch 3941B412

just like in MIA's guide. just start with your cpu and leave your ram on auto and run it out around 1600mhz and run your qpi at the lowest ratio to start out. get your max bclk figured out 1st. once you start going above 200 bclk you will notice your expensive high speed ram you wasted 300 bux on doesnt want to run at 2500mhz. so run it around 1600 - 1800 and just get it as tight as possible. once your ram is maxed out you can start bumping up your qpi ratio and run a spi 1m and watch your time get better and better as your raise the qpi ratio. just keep going on the qpi until you error out and keep the last best qpi you had that was the highest stable. if you think your ram has some more juice in it go back and see if you can make it run a bit higher or tighten it some more. just get it all working together and find your sweetest spot (best bclk, cpu ratio, qpi, ram speed/timings) now you are ready to start benching the prerequisites ie. spi 1m, 32m, pifast, cpuz, 3dm 2001-vantage, am3 etc. etc. use the latest cpuz (they fixed the ram bug finally) submit and have fun!

[radaja]

heres my new kit of ram at 1600 and 1800 6-9-6-24



20x200@4000 ddr3-1600 6-9-6-24


22x180@3960 ddr3-1800 6-9-6-24


havent really tried pushing the cpu yet,and my new i7-920 and X58 board
gets here tomorrow so i'll be testing it out next,not sure when i'll get back
to the i3-530 or even if i do.all depends on how well my new setup OC's

[WhiteFireDragon]

radaja, always chasing the overclocks any many different platforms . and i like how your idle temps are way below ambient (yeah i know, it's just inaccurate software readings).

how do you guys find what the VID is on these chips? realtemp does not display them.

[radaja]

im using AC so its very cold,about 4c-5c air blowing on my cpu with a 5000RPM fan.so mine are accurate.
with mine to find the vid just load optimized defaults the reboot set your hardrives and stuff the way you want them
the disable the advance cpu features(speedstep/EIST) and reboot and do either of these.

1.go back into bios and see what auto set your vcore to. or
2.boot into windows and start the software that came with MB(ET6)and open voltage page to see what vcore auto set.

[PiLsY]

I have another 2 to add - one poor and discarded, the other still working on it .

3941B415 - my original 530. Vid 1.1875v. 4.4ghz ht on @ 1.40v 96c/91c w/ mem at 2000mhz 8-9-8 (needs 0.04v more vcore for 10x mem compared to 8x mem).
3943A999 - terrible batch. Vid 1.2875v. Runs very cool though. Max clock 4.32ghz HT on @ 1.46v @ 83c/79c linx.
L945B968 - runs VERY hot. Vid 1.15625v. Still testing but i'm going ot need water for this one. So far 4.0ghz @ 1.19v @ 71c/67c. 12c hotter than my 3941B @ 4.0ghz/1.19v.

Still not seen anything that can approach 4.5ghz HT on no matter what volts I throw at it. Think you need to look out for stuff made before '09 week 40. Newer batches don't seem to be clocking as well.

[PiLsY]

L945B968 - additional core temp under load is from running dynamic vid. My other 530's do not behave in this way. By manually setting the same vcore as supplied by using Dvid Linx is generating a max load temp 10 to 12c lower on average. Very strange behaviour - have repeated this three times now including swapping to 3941B415 and back again. Definitely not a bad socket contact or heatsink mount.

Also Everest reports lower idle wattage when using fixed voltage compared to dvid when overclocked.

hey raj. I'll send the G6950 results when I get home. I benched all weekend.

here we go.

http://hwbot.org/community/submissio...950_9sec_453ms

I actually had a cpuz submission at 4890mhz spi 1m @ 9.39sec but I screwed up and the ss was blnk. I think I hit ctrl c and copied in paint instead of pasting so I ended up with a blank jpg. i may have submitted a live cpuz validation but I cant remember. Is there a way to see all my validations of cpuz? I really wish I had this cpu on a board that gets better bcklk. my max III formula seemed to max out around 230 or so. after that it just wouldnt go. there was a lot of room left in this cpu. I think I only scratched the surface of this g6950.

[LagunaX]

Crap I got a L942B539 i3 540.
At least it is MALAY and not from Crappy Rica.
Well I'll give it a go anyways when I build and see what the vid is (use coretemp for vid, right?).
Might be surprised, who knows?

[radaja]

Well I'll give it a go anyways when I build and see what the vid is (use coretemp for vid, right?).

with your gigabyte board just load optimized defaults and reboot and go back into bios and see what auto sets as vcore,thats the vid

[PiLsY]

My reported bios vid changes. Can report anywhere from 1.05625v to 1.18750v - seems to be stability related. Thing is when I get it stable it them "remembers" the last vid it set until I get unstable again or clear cmos.

Wouldnt trust the bios vid.

CPUz can read the vid if you alter the cpuz.ini file. Edit "Sensor=1" to read "Sensor=0" and it will display your vid rather than reading your current voltage.

[EDIT - Just tested this and its not working on my i3/P55. Works fine on my E8500/Q35 though. Don't know if its a motherboard issue or it doesnt work with i* cpu's?]

[radaja]

all my gigabyte boards(P45/P55/H55/X58)have worked flawlessly in this regard.disable advance cpu features
and leave vcore on auto and it shows what the cpu has programmed into it as it default vcore.

hey radaja or anyone else in the thread.. I had some fun last night with the i5 660 on the maximus III formula. hwbot seems to be down at the moment so I'll try to send some screens instead and you can validate later. is there a way I can log into cpuz canard and log into my account and see my submissions or does it not keep track by username and email? I really need to get the valid id off a particular G6950 bench. I think I had something good and I never saved a screenshot but I did submit to the database online and got a url but I have no idea what it was!

[radaja]

i dont know on that.there should be a way to recover old url's.i know ive lost a lot of them and cant remember what happened to them.

EDIT- i just logged into this url and it brought up all my submissions

sweet! hang on! here are the i5 660 results from last night. I ran out of ln2 a bit early. I was being such a puss with the vcore. I shoulda just cranked it from the getgo. oh well at least the cpu still works. I gotta say this maximus 3 Extreme has been to hell and back and it always works. I mustve done a really good job when I sprayed it down with conformal coating. I was just getting started





its funny. I dont know if I would consider it cheating but pay attention to the cpuz screens you see on hwbot. a lot of them disable cores. You can get gains by disabling and shutting off hyper threading and doesnt effect spi. I guess its legal but its sorta bullcrap cuz you arent really in the same category anymore. I can see using less memory..etc. but disabling cores to get ahead of everyone else? anyone want to elaborate on this?

[radaja]

yea with my first i3-530 i was trying to do 5.GHz like others and i later noticed they were only using two cores(HT/off)
great results trans am

Believe me man I've tried every combination of bios settings to try and sort this. If I enable dynamic vid my vid changes as I scroll between the voltage options. Now confirmed on 4 cpu's with this board. I suspected the cpu socket at first but everything checks out fine. Mine is an old generation foxconn socket, been keeping a careful eye on it.

Another one tested, this is my keeper.

L945B952 Vid 1.09375v.
3.9ghz 1.096v | 4.2ghz 1.15v | 4.4ghz 1.25v | 4.52ghz 1.32v
Bclk max stable : 239 @ 1.26vtt | Benchable 244 @ 1.34vtt
Mem max stable : 2022mhz @ 8-9-8-24-2T-88 | 1820 @ 6-8-6-20-2T-72 | 1916 @ 9-9-9-24-1T-122. 2x2GB G.Skill Eco @ 1.54v.

This cpu is the hottest thing this side of the sun. My zalman 9300 just cannot cope with it. Load temps are ridiculous. 4.52 HT on @ 1.32v gives load temps of 97c in linx. Hoping to get water fitted this weekend, may be held up if the res doesnt show in time. Likes the 19x multi, getting 60mhz more cpu same volts compared to any other multi. Limited by bclk now, cant figure out whats stopping me. Could just be P55 limitation, not seen any other P55 rigs running 235+ 24/7 stable.

Will upload 20 run linx later today.

[nolonger]

I have a Core i5 650.
Batch # is L936B721
Max I've had it was 4.25GHz stable with 1.35V vCore.

[PiLsY]

Better late than never but...



Doesn't need that much vcore - was using the same vcore/vtt from the old chip. Vcore now down to 1.3875 in bios.

Now tweaking memory @ 8x. Can't get 7-9-7 stable at the moment, but it may just need subtiming tweaks. 1900+ at CL 7 is going to push the vtt a bit hard for 24/7 I think. Still learning with this G.Skill eco though, but im loving not having had to use more than 1.54 vdimm so far. Only thing is 1T command rate seems to knock off ~100mhz memory speed. Haven't been able to get it back with voltage, it just stops being stable.

[radaja]

very nice PiLsY

[trans am]

Yeah good going pilsy! Im benching tonight on h55m-usb3
did the cold boot mod and im ripping in at -150c!

i have the i5 660 strapped so expect some good stuff!

[radaja]

looking forwards to your results trans am

[OC Nub]

Picked up an i3-530 today, seems to be a decent chip.
