So I have managed to play with the I7 after work, to see how it clocks, only spent an hour or so with the setup but it looks good.

so I use the i7 920 http://www.overclockers.co.uk/showp...0 2.66Ghz (Nehalem) (Socket LGA1366) - Retail

Asus P6T deluxe http://www.overclockers.co.uk/showp...58 (Socket 1366) PCI-Express DDR3 Motherboard

some Kinston Hyper-X 1800mhz ram http://www.overclockers.co.uk/showp...8 (2x1GB) Dual Channel DDR3 (KHX14400D3K2/2GX)


I Installed windows on the system, install the drivers, benchmarks, testing progs so on, then jump into the Bios, which has a lot of overclocking options.

Tried a 4Ghz overclock... 1.3V, 200fsb x20 multi, ram at 1600mhz 20,8,8,8 few other tweaks to the bios settings and manage to get the system into windows,
this is with the retail cooler as well. Wasn't too stable failed prime in a few mins and I didn't want to push the volts any more on the stock cooler.

Tried 3.8ghz 1.3v, 190fsb x20 multi, so on, so on, this was about half our prime stable, never failed but was getting on the warm side,
so I stopped the test, went into the Bios and tried 1.25V,agian prime stable for about half hour.

This is as far as I got at the moment, so I'm hoping for Big things tomorrow and more testing with better cooling.
 
4ghz not bad going, what were the temps like with the Intel stock cooler at the various speeds.
 
nice. keep us posted

and from the benches I've seen 3d performance is quite a bit better than Core2
 
Nice!

The 920 chip is priced "OK" given the hype etc. that preceded it.

Can't wait to see some benching!

Thanks for your input.

Would be nice if the 2.66 i7 can break 4ghz easily on water. Makes you wonder what the extreme is capable of when pushed to the limits

Have a read of that :)

I have a several problems with that review:

1. the i7 is at 3.2Ghz compared with a 3Ghz E8xxx cpu so running at 6.6% quicker so all results for the i7 should be 6.67% quicker anyway in cpu limited games which will then make the real life gains a less than they report.

2. Some of the games tested do benefit from quad cores so how much of the gain is from the i7 or just the extra cores. Would have been much fairer to have had a q9xxx at 3.2Ghz compared to it.

3. All the comparison results are for 2 and 3 way SLI/xfire. A lot of people don't have those kind of setups so would have been nice to have a straight forward q9xxx @3.2Ghz vs i7 with just a single GTX280 or 4870x2 as a comparison.

4. And lastly there are a few anomolies in their results with GTX260's beating GTX280's as single cards. Makes me doubt their other figures if they can't even get that right.

Yes the i7 is fantastic for multi highend gpu setups but what about us "normal" folk? I want to see how much (if any) gain there would be with a single card setup.

Look at Earlstreetblue and his single 4870. I can actually forsee he might get worse results in games than a highend 775 rig would get.

So come on Tizor, give us some sensible comparisons and not tri-sli GTX280's

Hit the nail on the head. Any "review" that claims a "like for like" comparison and then chooses to use a dual-core C2D that's clocked 200MHz slower than the other part lacks serious credibility in my eyes. 200MHz is enough to skew some benchmarks, and comparing quad-core (i7) to dual-core is ridiculous.

I know it's really annoying. It's not exactly difficult to get it right..........dude! :mad:
 
Slight update, not has a lot of time to play today with being very busy.

but I set the Cpu to 3.6ghz, 1.200v and left prime on all day, was still going strong at 5:30pm, so about 9 hours of prime.

This was with the stock cooler aswell load temps 65/70 oC.
