So you decided to give it a whirlpool, err ... whirl then. Good going cob.

 

[slickncghia]

yeah im spreading the love.

i woudnt want to prime95 it at these temps though. idle ~ 54 probably be close to 90 under full load. i need an aftermarket cooler

 

[lashton]

Dont worry about it jz. He's a jackass

How dare you even assume to know who i am, what I do, you dont even know me, I dont know you so dont call people you dont know jack asses typical troll

 

[slickncghia]

jackass, such a yank word, i love it



superpi 10.015 @ 4.2ghz

4.2ghz seems about the limmit with stock cooling for me i dont want to go too high with vcore.

with some tweaking of memory ect i think i could get it under 10secs on stock cooling

Intel finally has the specs posted on their website for the i5 750.

[ibnsina]

You ordered this already? The i5 is hasn't been released to sell yet ?
Why did you use turbo overclock, that's noobie. Also, that video card is funny, I guess you do not play much games?

Is on sale now at bestbuy.com (low stock)

NCIX has lots of Core i5 750 CPUs in stock as well as a nice choice of motherboards and dual channel DDR3 memory kits. They are a Canadian company but have a U.S. website and usually ship by UPS to U.S. destinations.

and for Canadian buyers, here's a sweet little promotion:

haha...this is the only time I know of us in Aus or NZ being ahead of America in anything!! so funny..... 😛.....

what kinda coolers are we looking at using here, if i wanted to keep it stable at ~3.6, and my ambient are probably higher than in NZ (im in QLD)? is there any equivalent to the noctua nh-u12p for the 1156 socket?

 

[slickncghia]

i will struggle fitting the full size heatsinks in my case without removing my super flash side fan.

so im waiting eagerly for some shorter towers. or maybe a corsair h50 if they bring it out for the 1156

all i know is i need it soon. i think with good cooling it will be stable on 4ghz

 

[micky_lund]

haha....like from 3.6+ gives any benefit u can see....

 

[slickncghia]

just leave it on 3.4 with stock volts and stock cooling then

save the money on an aftermarket cooler

 

[slickncghia]

i almost pulled the e-trigger on a noctura. i might try and hold out as long as i can as im sure there will be some more stuff released soon

You must be rich!

Do you know that even the OEM CPU in NZ is about $80NZD more than the retail packaged CPU in Taiwan? I can get the whole system from the U.S./ Taiwan for $230NZD less with EMS/UPS and money transfer cost included. p.s. You could have saved even more by getting it from the U.S. if the cost of EMS in U.S. was the same as that of in Taiwan.

This way, you can earn lots of money when you want to upgrade by selling it on TradeMe(most popular NZ online auction) where full of idiots who would pay for more than the brand new components prices in NZ which are ridiculous expensive already.

I hope that NewEgg/Micro Center will accept international order at local currency with the price being the same as U.S. some day in the future, so there will be no need for me to spend a lot of time in ordering my PC parts from foreign countries.

 

[slickncghia]

mine was 278 AUD plus delivery and $163 aud for the mobo.

not too bad for early addoption. though they have dropped a little already with msy picking them up

 

[slickncghia]

i wish coolers would hurry up. got it to 9.906 superpi 1m.

its just too hot though

 

[auchi]

From http://processorfinder.intel.com/Details.aspx?sSpec=SLBLC
Thermal Specification: 72.7°C

Does this mean the max temp for this chip is 72,7 ºC?
Doesnt sound like a lot when one can read 90ºC with some of your tests.

I'm planning on getting a new system and even thou I've read plenty about OC I never really try it.
How long did it took you to achieve such results, I mean, it seems fairly simple.

jy_nz I failed to understand one thing, did you or did you not had the need to disable/enable any BIOS option for the cpu to scale up to x24 on single threads?

 

[slickncghia]

generally you wouldnt want something to live too long at high temps. the consensus on temp max for short periods for most chips seems to be around 100degs.

but i wouldnt want anything 24/7 that maxed out at over 75deg c. which means it would spend most of its time 40-60.

overclocking is easy.

basically. turn off all the "auto" and special features in bios
up the bclk (Front side bus) bit by bit
if you need more volts then up them

 

[auchi]

Ye,but even for intel 75ºC would get me a bit nervous 😛
I wouldnt want to turn off the boost function in this chip eh 😛 But I wonder,isnt it possible to overclock and keep some mobo functions active like i.e fan xpert in the Asus P7P55D PRO, which is basically a vent controller.

Its funny thou I have been reading about amd oc since its the system I have now and theres a lot of fsb talking and how that relates to ram, lots of calculus and so on.
In this chips seems like thats not really a concern, other than getting ram that doesnt go over the 1,65v.

How did you get 3Dmark Vantage running on win 7?

Because I always get the following error message during system scan:

System info scan failed.

I run Win 7 RC7100 x64 on a Core I5 processor.

 

[slickncghia]

hmmm not sure but ive run 3dmark05 and 3d mark o6.

just some benchies for yall... after a slight tickle to the graphics card

i5 750 @ 4ghz (still got more in it)
gtx 275 @ 722/15971232 (still got more in it)
stock cooling

PC mark 06 – 21296

btw stock and stock the 3d 06 was around a touch over 17000.

3.78 GHz man this is looking too easy.

OK so with stock cooler and stock volts, it's running at 180MHz base that's 3.6 GHz (and 3.78 GHz on the x21 turbo). Temps are sitting at 57 deg C max with just Core Temp and CPU-Z running.

Running wPrime 1024M pushed things up to 75 deg C which might be a bit much.

I'll leave it to idle over lunch and see if it's still stable.

what voltage did u need to run 100% stable at that speed?

i got i5 750 two days ago but mine needs alot more voltage compared to urs, i'm using NH-U12P SE.
http://img443.imageshack.us/img443/3899/i5750.jpg

let me know if have you found out the minimum voltage required to run 3.6-4.0ghz 100% stable.

 

[zzan]

O.P. can you at least run 3DMark06 or Prime95 for 5 mins when overclocked?

How come i can't find one 1 proper overclock on the net.. 🙁

OK please note that this is taken with a 170 MHz base clock. That base x20 equals the 3.4 GHz as reported by 3DMark06 and x24 equals the 4GHz that's reached when the CPU has two or fewer cores working.

I think if you look at my post of 09-07-2009 at 07:24:23 PM you’ll see 9 minutes and 49.6 seconds of Super PI 32M at 4.2 GHz. That was with a base clock of 175 MHz.

170 to 175 MHz is pretty much the limit of the stock Intel heatsink I have.

As I noted earlier in an earlier post all the OC results were done with the MSI BIOS CPU volts set to Auto and the BIOS reports Vcore to be 1.288V. These settings are still greyed out in the CD53 BIOS at Version 1.1 although MSI have just released V1.2 I’ve still to try that.

I measured the Vcore using a DVM connected to the test point on the MSI MB and comapred that to what's reported by CPU-Z. Generally the two agree to within 100 mV or so. There probably some droop between the regulators and the chip. At around 175 MHz base clock (4.2 GHz at x24 turbo) CPU-Z usually reports between 1.34 and 1.44V while my DVM reads hovers just under 1.5V.

If you want more detailed overclock results it might be best to work some more on your system or talk to slickncghia. It takes time to do these tests; people often forget that one mistake that blue screens Windows means you might have to reload the OS which is all a bit tedious. The purpose of this thread was to show people some of the potential of the i5. I never claimed my setup would run 24x7 at 4.2 GHz but what it does do is pretty amazing for such a low cost chip.
