Just finished my budget i5 750 build as follows:

CPU: i5 750 base clock @ 150 MHz for mild 3 GHz (3.15 GHz turbo) overclock.

Memory: 2x Kingston ValueRam 2GB 1333MHz DDR3 @ 1.5V
Note Intel states that you can’t use RAM that needs more than 1.65 volts, typical of high performance memory.

MB: MSI P55-CD53 a bit limited but supports Intel SATA Raid.

The CPU, MB and memory came as a bundle for around US$500.

HDD: 2x Seagate Barracuda 7200.12 500GB in Raid 0
GPU: Nvidia stock 9600GT (don’t laugh I already had one)

OS: Windows 7 Home Ultimate tested in both 32 and 64 bit versions

Results:

3DMark06 Windows 7 32 bit
GPU 11335 CPU 4296

3DMark06 Windows 7 64 bit
GPU 11330 CPU 4302

Nice step up from my old Pentium 540!
 
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?
 
The i5 has been for sale in NZ for more than two weeks. I got mine last Firsday and built the rig over the weekend. This was a budget build ... had to make do with the GPU I had for the moment.

 
How much was the final build man? What's NZ?
I just searched on the sites like newegg..and others and cant find it.
The release date for i5 750 says september 8th on google..
and that's a great stepup from pentium 540 lol, you not gaming?
 
Go for 4Ghz :)
Click to expand...

I doubt it overclocks like the i7 920, you probably need to overvolt a lot for i5 750. 4GHZ on air will be quite hot anyways and there will not be much of a difference maybe no difference at all in performance in games opposing 3.6-3.8ghz
 
NZ = New Zealand, it's a country. Part of the great alliance of five English-speaking countries (Australia, Canada, New Zealand, the United Kingdom and the United States) but I reckon that Intel thinks we're part of Asia so we get stuff early.

I'm using the stock Intel cooler and temps get to 73 deg C when running wPime 1024M accross all 4 cores. Takes 332 seconds but I'll need a better heatsink to go much past 3.15 GHz. Psychosaydie, yes I've heard of 4GHz on air out of China or Taiwan...
 
haha i knew NZ= new zealand but i thought you were referring to an online store, so then i mentioned newegg..etc..
im surprised it's released in NZ because it says sept 8th release date. weird

too bad i dnt know any 1156 socket coolers..
 
Also on the turbo mode well that's built into the i5 chip. The i5 750 runs at 20x base clock and jumps by iteself to 21x if the CPU is not too hot and it's busy. So at idle it runs at around x9 (1.35 GHz) steps up to 20x (3GHz for small jobs) and then jumps to 21x (3.15 GHz) when you really give it something to do.

What puzzels me slightlty is that the QPI link clock shows as 2.7 GHz in CPU-Z 1.52.2 but shows up as 5.4 GHz in the MSI BIOS. Still it's early days for the i5 and the MSI BIOS is like Rev 1.0!

Plenty of places in NZ selling the i5, like there are 60 prices listed here:

http://www.pricespy.co.nz/pno_16226.html
 
what the..the price is so high, i read somewhere the i5 750 should only be around 200 dollars. USD, maybe cuz of new zealand currency (just did some conversion, the price is around that in nz dollar lol), damn that sucks for you guys

i might go for the i5 750 over the i7 920, we'll see some good reviews about it in these weeks. but buying the i7 920 will future proof more i guess, not that much more money spent overall i guess
 
Those Pricespy prices are in NZ dollars. To get US dollars you need to multiply by the exchage rate. So typical prices on that list are in the range US$255 to US$265 retail.

The trade prices for i5/i7 here are:

i5 750 US$255
i7 920 US$315
i7 860 US$342
i7 950 US$652
i7 870 US$672
i7 975 US$1,232

Most stores here sell the CPU real close to trade price and make their money other other associated items.

I serioulsy considered the i7 860 but the i7 mobos are really expensive compared to the i5 units. If you look around the benchmarks you'll see the i5 is able to run pretty close to the i7 920 anyway. Given how few games and things seem to be multi-threaded all the extra CPU threads are really not going to help much yet.

And when they do ... there will be new drool worthy Intel silicon for sale anyway!

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.
 
There ya go OK at 4.020 GHz here it is:

Still stock volts and HS ...

 
Thanks for sharing your new i5 with us.

I've updated i7 Turbo which is a good program to monitor the multiplier on these new CPUs.

http://www.fileden.com/files/2008/3/3/1794507/Turbo.zip

The Core i5 750 has 4 bins of turbo boost available when running single threaded tasks if you enable C3/C6 in the bios and your motherboard properly supports this feature. On the previous socket 1366 boards, most of them limited you to a +1 turbo boost as soon as the BCLK was raised. The 1156 boards might have a similar limitation. These are looking like a nice alternative to the socket 775 45nm Quads.
 
Hi unclewebb, thanks for the utility and the BIOS hint. Here is what I've found:

243hf.jpg


Now the MSI BIOS had no specific C3/C6 enable, however there was a 'Intel C-State' Enable/Disable function that defaults to Disable. Enabling that and CPU-Z showed rare jumps to x24 (3.6 GHz in my case) but it was not sustained even with a single threaded task. It would jump to x24 at the start of the task then settled back to x21.

Going back to the BIOS again there was an associated 'OverSpeed Protection' Enable/Disable function that defaults to Enable. Disabling that and my CPU was happy to sit at x24 for a single threaded application but wouldn't hold that for multi threaded applications (in my example I used wPrime which allows you to set the number of threads to be used).

Your utility would not record the x24 mult being used in the Max box, always topping out to x21. Perhaps I've not understood this bit it properly?

However the individual thread boxes showed average rates approaching x24 for two threads (I would have only expected 1, but it looks like the Windows 7 scheduler is tossing the one thread accross two cores thus giving the approx 50% loading on each core).


And just for Psychosaysdie here is a final insanity:

Like, this is my work desktop ... at stock ... and in my best Chief Engineer Scotty voice "We need more cooling Captian!"
 



this is a load of crap and hes lying, Im from NMZ and the Core i5 has an international release date, hes talkign through a hole in his a$$, I retail hardware in NZ he did NOT get this early, it arrived with the NZ supplier yesterday!

Stop lying you fool
 
HAHA nice screenshot of the bill man that owned his ass but im still pretty surprised it got released so early in NZ. You should of erased the full address for security reasons, there's a lot of weird people here, they might be able to track you down and rape you lol..

Damn, I've never knew that the i5 750 is such a great overclocker..I'm so jealous and you making me wanting to get this so bad, at over 4.0ghz with stock cooler and voltage thats amazing. Maybe you just a lucky guy with a good sample of the chip. Who knows. sigh.
edit somethings wrong here man: you said stock voltage, the first pic is 1.112vcore for 4.020ghz and then its 1.320vcore for 3.6ghz and then 1.344vcore for 4.3ghz

is there any good 1156 coolers out there. am also waiting for some good reviews on the i5 750 vs i7 920 overclocking articles. then ill decide which to buy
 
Well it shouldn't be about owning anyone’s ass .... This is about Overclocking!

There are tons of retailers selling i5 in NZ as the retail poster would know if he rang around the Pricespy list I posted earlier. Hell, you can buy them on Trade Me (the NZ equivalent of eBay). By the way as a courtesy to retailers out there I should point out that the image above is from a well know NZ trade supplier and reflects prices available to large corporate buyers. Hobby users should not expect these prices if you are only buying a few bits retail, YMMV. The guy behind the counter has to make something to cover all those ‘interesting’ retail questions! Anyway how does Mr Ashton think you fake up pictures so easily? Unclewebb posted details of his i7 Turbo program and I posted an image of it on my system an hour later. Have to be a magician to Photoshop that…

On your subject of heat sinks – no I’ve not found anything yet. As you probably know the LGA1336 socket heat sink push pins are on 80mm centres whereas the LGA1156 has 75mm centres. So it would look like you might be able to fudge a water block mounting by drilling or filing elongated holes in the water block mountings. Might just need to wait for manufacturers to introduce LGA1156 mounting kits as with this kind of overcooking there’s going to be demand.

By the way I’m actually the second person in our company to run up an i5, the other guy got his two weeks ago! So we're learing fast.
 
hey maybe you didnt see the edit i posted but here it is

edit somethings wrong here man: you said stock voltage, the first pic is 1.112vcore for 4.020ghz and then 2nd pic its 1.320vcore for 3.6ghz and then 3rd pic 1.344vcore for 4.3ghz

i just read some articles that the i5s were released in china in august..lol im in canada..its still not released same with US
also they did 4.4ghz with stock cooler, this i5 750 is driving me nuts.
Cheaper FASTER HOW COULD THIS BE LOL
 
By stock volts I mean that I didn't change the mother board BIOS settings.

However the CPU itself can vary the applied voltage by altering its 6 bit VID output over a 64 step range (VID = voltage identification). The VID output is connected to the multi-phase power supply system on the mobo. Dr MOS in MSI speak.

Have a read of this item:

http://en.expreview.com/2009/08/19/thorough-review-of-intel-core-i5-750.html/1

and note comments on page 11.

Also Intel states in:

http://download.intel.com/design/processor/datashts/320834.pdf

"The voltage set by the VID signals is the reference voltage regulator output voltage to
be delivered to the processor VCC pins. VID signals are CMOS push/pull drivers. Refer
to Table 2-15 for the DC specifications for these signals. The VID codes will change due
to temperature and/or current load changes in order to minimize the power of the part.
A voltage range is provided in Table 2-7. The specifications have been set such that one
voltage regulator can operate with all supported frequencies."

Note the comment that the VID codes are changed by the CPU according to load (my italics). Although this pdf is for the i7 it is much the same for the i5, so I understand.

Also have a look at the sticky 'Core i7 and Core 2 Temperature Guide' - by CompuTronix in this forum.
 
Yes I found the forum...

Let's see what we can do. This is at my standard working overclock - like I started this whole thread at.

wprime.jpg


Now I know this is at 150 MHz base - I need to run it up again tomorrow. But please not that the high OC are clearly going to be limited by the cooling.
 
you didnt have to type all that, you could of just said you left the voltage at Auto.

Also why is it at 3.1ghz(last pic) i thought ur overclock is at over 4ghz or you reach 4.3ghz just enough for a screenshot but will crash with prime95?
have you ran prime95 or any other stress programs for at least an hour testin?

there is no HT on i5 750 right?
 


Well then techpac are in a whole heap of trouble this was to be released for shipping today, congrats you just got them in trouble with intel
