[Bit-Tech]Overclocking Intel's i7 920

[ascstinger]

those are nice benching clocks, but what about a 24/7-acceptable oc?

 

[Fitseries3]

here ya go.........

2XXXmhz ram on x58 in tripple channel.

4.2ghz is fine for 24/7

 

[Fitseries3]

remember that garbage that the core voltage is directly linked to the ram voltage?

myth dispelled....

give me a min to explain.....

QPI/dram voltage is related to the path between the memory controller and the actual ram itself. this needs to be within .5v of the vcore to prevent damage to the memory controller.
Dram bus voltage is the actual voltage that the ram is running at.... IE: Vdimm, Vram, Vmem, etc. this should be as close as possible to within .5v from the qpi/dram voltage.

 

[Fitseries3]

While Asus and Intel (rightly) scare everyone (read: uneducated) into thinking that 1.65V on the DRAM voltage should be the absolute limit before you reach for the fire-blanket, all that's really needed it to obey this: keep the CPU uncore voltage within 0.5V difference of the DRAM voltage and there's no problem. Over this potential difference and you’ll greatly increase the chance of CPU death, but it certainly won't happen instantly in a big ball of fail fire if you make a mistake.

I'm gone for just a few hours and Jacob Freeman @ EVGA somehow manages to overclock the 2.66GHz Core i7 920 all the way up to 4.30GHz using just air cooling and the EVGA X58 motherboard!

This is ridiculous, and once again proves the power of Nehalem. I've been stressing over this CPU for months now, and by now you should know the reason.

Jacob @ EVGA:


Some testing on the EVGA X58, with the Core i7 CPU.

100% Air Cooling

Still testing the max QPI...

Some temps. This is at the same clocks.

I will get some memory numbers next.

i posted that earlier.

damn... check my link again.... 4.5ghz has been reached. i dont think you'd need a cascade to do it though. 4.4ghz on air but 4.5ghz on -100c? :shadedshu

dude 5ghz he isnt trying

As for the cascade, I think you're right Fits. Wonder if anyone else can beat it.

 

[Fitseries3]

i'll try soon.

i doubt its that hard. just have to figure out a whole new way to OC.

 

[InnocentCriminal]

I'm going to have to try really hard in holding out (and not purchasing stuff). I really want people to start dicking about with Foxconn's Bloodrage and the 920 - really want that board!

 

[kyle2020]

That bloodrage does look a nice board. Holding out on new i7's wont be hard for me, bloody skint at the minute haha.

So, 4.5Ghz+ already? do you people ever sleep?! haha. Does anyone (including you fit) have any 3dmark results?

oh and innocent, yhpm.

Thanks man!

Awwww! I want to be able to test pre-release hardware. Fingers crossed I win the lottery tonight.

Some info, this time from AnandTech and Patriot...

We have been busily preparing an X58 motherboard roundup and overclocking guide that will be published shortly. During the course of testing over the past few weeks we have encountered more than our fair share of problems. Problems ranged from poor GPU driver support to BIOS releases that had difficulty booting 12GB memory configuration much less offering a decent performance or overclocking experience.

.. I would have posted a new thread about it, but I know that might upset some forum users.

 

[Binge]

You're right! I would have laid down the smack again That's to be expected though with brand new tech and the inevitable OC.

 

[Fitseries3]

oooooooooooooooooooooooo

 

[Solaris17]

oooooooooooooooooooooooo

i want ln2 or cascade on both the proc and NB and i want to see 5Ghz+ with a proc that cold and that much voltage (not talking about this pic spacifically) i want 5Ghz or they aint trying.

 

[Fitseries3]

we will soon know.....
