Ok from the get go, if there is a class below NOOB that is me (when it comes to over clocking). However I have a build (see below) that I would love to OC but I cannot find any help or guides available. Plenty of help for I7 920's but nothing for I7 975. I am looking for someone to take a young apprentice under his wing an walk him through the basics of getting started.

CPU I7 975 Extreem
MOB Gigabyte EX58 Extreme
PS Kingwin Mach 1 (1000W)
RAM OCZ Platinum 1800 Mhz (3X2048)
CPU COOLER Ultra ChillTec Thermoelectric cooler
VIDEO GForce GTX 9800 (2 X SLI)
OPTICAL Liteon BD Burner
OS Windows 7 Ultimate

More about : 975

I second that^^^

To the OP, if you can return that CPU then go ahead, if not then im sorry to tell you that you got jacked!! The 975 was made to lure in the idiots, making them think that by slapping an EXTREME logo on it they are getting an UBER CPU... Anyways the 975 basically overclocks the same as the 920 and 950 with a few exeptions.

Start here :

if you have any questions Overshocked will be glad to help you out, ohh and make sure that Chilltec is working properly, you do not want to fry your 1k CPU!!!

The 975 should be capable of going a bit higher than the 920 and 950. It won't go a ton higher, but there should be a definite advantage of a few hundred megahertz or so. They are based on the same die, but Intel does bin the parts, with the best ones becoming i7 EE and Xeon chips (and the worse ones becoming the cheaper 950 and 920 chips). Whether that's worth the cost is dependent on the individual - it isn't always worth it, but there are people for whom it is worth the money.

As for overclocking, it is primarily the same as overclocking an i7-920, with the exception that you could also change the multiplier to give you more options. All of the settings aside from the multiplier act the same, so you should be able to use a 920 guide for the most part.

I need to agree with zipzoomflyhigh, just noobs are buying that CPU to overclock with air cooler, cause you won't be able to OC it much more than 920 on air. if you would be using passive cooling or similar than you can achieve better results than 920 can.
Do as OvrClkr said, try to return it and get yourself 920.

TBH probably you have more than enough money so you even won't consider this option, but if you would do so, you could donate those 750$ for people in Haiti.

linaaslt: It should still OC higher on air than a 920. The difference won't be huge, but it should be more stable on less voltage because it's a higher binned chip. Intel's 45nm process is pretty mature, so all chips can reach quite good clocks, but there is still a difference (though not a large one to be sure).

Yea, but the question is : Would you pay the extra 750.00$ for a few extra Mhz?

The record for the 975 is 6.1Ghz , the 920's record is 5.7Ghz .... and those are cherry picked... not worth the premium IMO.....

I never at anytime indicated that there was a cost factor involved. This system was assembled for a verry different reason, now OC has come up and we want to give it a try. The sytem did not cost me a dime to put together.

Those records are under LN2, and not all that representative.

As for would I pay it? Yes, in some cases. I did pay the extra for my 965, and I got 4.2GHz out of it on air. Very few C0 920s could pull that off (and D0 didn't come out until well after I put my system together). Am I happy with my 965? Heck yes.

Of course they were under LN2, but that makes it even worse cause you can get over 4.2Ghz with little effort using a D0 on Air. I know more than 10 peeps here on toms including Overshocked that run their 920's at over 4Ghz.

Your case is different, if I had the cash for such a CPU i would have not hesitated. My issue is specifically with the 975 and its price to performance ratio. I can also understand if the user got it for less cash or sponsored and will use the CPU stickly for LN2 bench records. But to pay 1k knowing that you can do the same for much less is just non-sense....

Well I took the advice from those in the know (on this forum) and got a I7 920 overclock guide form gigabyte (exact motherboard that I am using). Not sure I fully understand what I did, but here is what I ended up with. I can get 4.4 GHz @ 51 c under 100% load (sp2004 X8) of over 2 hrs. Is there any little tweeks I can make to get it higher (Blue screen at 4.5 GHz before load testing started) or is this the best I can hope for under air?

51c at 4.4Ghz is unlikely unless you are cooling the CPU with DICE or any other extreme cooling method....

What program are you using to monitor the CPU temp?

Nice overclock BTW ;)

I am using a chilltech ultra. I am taking the reading off the front panel. Is that display not reliable? I have not heard any negative feedback on the chiltech.

I have to retract earlier. 3.5 hrs in blue screened. Dialed back to 4.375 and re-testing.

then once installed, open up and click under Computer>Sensor and you will see all your temps =)





That is showing a cpu tump at 66 c. It is also giving me 4 core temps. Which temp do I want to watch, and what is the uper limit.

CPU temp is what you need to be looking at, don't pay attention to the individual core temp.

So you get 66c at idle or LOAD?

Under 100% load right now runing sp2004 8X one occurance per thread. Large, in-place FFTs-stress some Ram, priority 9. going on about 20 min so far.

Well 66c under LOAD is fine. Just make sure it does not go over 70c ...

Just to let you know, anything over 3.9/4Ghz is a waste unless you are benchmarking or trying to break a record. If you are not doing either my suggestion would be to lower the clocks a bit.

Pardon my ignorance, but why is 4 GHz the ceiling? I should have no problems at all with temp at 4 GHz.

4Ghz is not the ceiling but it is the sweet spot for most since anything over that is waste in terms of everyday usage/tasks =)

That's because people dont buy 975's to overclock.

You can get the 920 to 4gz for $750 less. Therefore only noobs buy 975's.



A little of the 920 nerd rage going on these days... anyone who doesn't buy a 920 and oc it to mid 3s or low 4 is a noob... a lot of nerd rage...
