Core i3 530 Overclocking worklog

[bt_medic04]

So the other day I took my friend to microcenter to purchase a new video card to replace his aging X1900XTX and stumbled across a pretty decent deal for an i3 530 for $99. well thats $25 cheaper than the egg, so i picked one up

anyway on to some specifics about this chip. its batch is L939B674 with a pack date of 12/07/09. stock voltage according to what my bios defaulted is 1.1875v and at stock speeds, it idles at 25c in a 21c ambient room under a corsair H50 with 2 fans in push pull.

right now im doing some stock voltage overclocking just to see how far it will go. currently testing the following:

145x22 (3.193ghz)
1.1875v Vcore
1.05v VTT
1.8v PLL
ram at DDR3 870 8-8-8-24 1.65v
Idle temp: 25c/25c
Load temp: 40c/40c

passed 13 minutes of Prime95 in place large FFTs. moving on up 266mhz on the core speed

Linky to a screen shot

32nm is pretty awesome right now! cant wait to see how far it'll go! be back later for some more

@ 3.7ghz w/ stock voltages running P95 in place large FFT's

4ghz @ stock voltage. been running P95 in place large FFT's for the last 33 minutes. tried booting at 4.08ghz and it failed to boot into windows. im suspecting that this is about as high as this chip will be able to go on stock voltage, which is quite awesome for a $99 processor

Very nice, Congrats.
I am looking at either an i3 or one of the 32nm i5's. Still undecided but either way all the results Ive seen have been great. Keep us posted.

[bt_medic04]

well you do get a higher multi with the 32nm i5's, but theyre a bit overpriced right now IMO. keep an eye on this thread and see what the max BclK is and decide if the higher multi is worth the extra cost

[bt_medic04]

4ghz is indeed stable at stock voltages

Nice work!

[OC Nub]

$99.00 is looking pretty good. Very nice results, keep pushing and keep us posted.

[bt_medic04]

4.4ghz validated. gonna test now

[bt_medic04]

been running P95 for the last 30 minutes with this

200x22
1.35v vcore
1.35v vtt
1.8v pll

Link

I think 24/7 sweet spot is going to be 4.3ghz as the settings for that are 196x22 1.2875v vcore, 1.2v vtt

i am playing with i3-530 with high bclk for few days



however when LinX temp reach 85C ++ with water cooling

[Vinas]

Is this with a 8800GTX? If so what speeds.

[atomic ferret]

Pretty darn good for only $99!!

[PatRaceTin]

Is this with a 8800GTX? If so what speeds.

yes XFX 8800GTX @ Core 630 Mem 1025 Shader 1635

[bt_medic04]

anyone know what the max "safe" VTT for the i3 as listed by intel is?

[OC Nub]

I believe it is 1.40vVTT and 1.40v Vcore, very nice results on your chip.

thanks OC_nub. thats exactly what i was looking for. anyway i put the i3 in an evga H55 motherboard. im pretty sure ill be able to get similar results on it compared to my P55 FTW. only thing thats annoying with that H55 is that it shows vcore adjustments as mW instead of say 1.1825v to 1.1875v. other than that, the bios looks very similar to that of the P55

[OC Nub]

^ Do you have the e657 FTW board? If so what bios are you on? I was wondering if you could open AFUWIN, its in the bios, and save the bios. I cant get my FTW board to flash to any bios past A29 I think it was. I get errors in W7 64, spent hours trying with no success. AFUWIN saves as a .ROM file which is what I need in order to flash this board.

Hi there, this is my new test on P55-UD6 and Core i3 530.

NICE! what ended up being stable clocks?

Yeah, i have the e657 FTW, not the nF200 or classy. Im running bios A51 and I cant update to A56 either in windows 7 64bit. I did safe my bios though for you and will upload it

4ghz is 8 hours prime stable at stock voltages, 4.3ghz looks like it will be the sweet spot as it runs with 1.2875v Vcore, 1.2v VTT. I just have to test it in my evga H55, but i have to head back to microcenter tomorrow as the kit of ram i have for that board was DOA. multiple errors in memtest86+ even at reduced speeds and timings paired with increased voltage 4.4ghz was able to run for 30 minutes in Prime 95 @ 1.35v Vcore, 1.35VTT. once i get the replacement kit of ram, ill try for another 8 hour run and i still have another .05v on the vcore and vtt until i leave the "safe zone"

That would be great, Thank you.

[WhiteFireDragon]

bt_medic04, do you think you can run a 1M superPi at 4.0ghz and 4.3ghz? trying to see if these are faster than c2d's at the same speeds. also, any way to measure the power draw from the wall with that vcore?

Hi there, this is my new test on P55-UD6 and Core i3 530.

4909 Mhz on air...

4.9 on air . is this chip batter than average or can i expect this with all i3's? btw, i love your sig pic. wonder where you got that from . i did a crummy job with that one you used, but this one i have now is a slightly better version.

[TheGoat Eater]

I was hitting 5+ on air with a megahalems and a slower fan today - on a Trinergy ... now I have the board prepped for some -160C action

[overclocking101]

wow maybe I will go with one of these dual cores! I was going to get an i7-860 but these results are impressive!
