Credit where credit is due i7 920 4.6ghz (ON AIR)

[Audigex]

2.66*4 = 10.64
4.6*3 = 13.8

So a 30% increase in speed (give or take, I know you can't really multiply cores by clock speed), at the expense of an unstable system. Decent effort on the clock, but I'd be more impressed by a lower clock speed with a stable system.

Also, comparing stock to overclocked is completely pointless.

I got my i7 2600k including HT to 4.8Ghz stable and below 75 degrees. I wanna see 5.0Ghz out of this thing. Also, doesn't reach those temps running BF3, that's because it isn't using all that extra power that's killing your CPU. Stop talking plop and get it back to stock or at least something acceptable.

I already said normal use is 50c and below BF3 no more than 70c (with 7970 oc xfire in the mix as well). A this moment in time is 45c just browsing etc.
As for the BF3 statement where you pull that one from, many are reporting only about 75% cpu usage, i think xfire 7970 oc do most of the work lol.
Your chip is how old and runs on how many watts??

Before any one else jumps in from just the first thread at least read this bit.

OC at 4.5ghz
Normal use 50c and below
BF3 no more than 70c
Stress testing 100% load now 92c max

So temp levels are between low 50c to max 70c, if thats not good enough on a 130w cpu, that was known for hot temps nothing ever will be, many thx and goodnight.

zuludawn, would you mind running cinebench on your system and posting the results, please?

 

[zuludawn]

Never used it before it any good or cpu to old?

4.5ghz

4.6ghz

 

[ThomasTheTankEngine]

Well as long as you're happy with it, that's the main thing.

Just don't blame us when you see the magic smoke.

Thank you for uploading those results for me, zuludawn. I was curious to see how well it compares to an equally clocked Sandy Bridge system. The difference is quite intriguing.

It wasn't a "special" chip the last time you posted it, nor is it now.

And just for the record, upgrading from Bloomfield @4.4GHz to SandyBridge-E @5GHz was most definitely worth it, so no, not "shame on Intel" at all.

 

[Yaayuh!]

Just out of interest, what overclock can you get out if with it actually being an i7 (TURN HT ON)

At bang on 4.6Ghz my IB 3770K scores 9.35pts.

Blimey thats a massive difference, just glad my 2x 7970 make up for the difference in games at 2560x1440. I was waiting for Ivy but could not justy swapping mb,cpu and memory when it would not improve any fps in gaming (as at 2560x1440 vsync on its solid 60fps everything maxed anyway.

Was not the cheapest option either at i already had a 920 oc at 4ghz, it was curiosity that killed the cat when i saw it advertised at a guaranteed 4.5ghz. On another night i had been drinking.

4.4 ghz with HT on. I still think its a good oc within normal usage.

Lesson learnt in this thread.
1. Dont drink and post
2. Dont drink and Ebay.

What doesn't get you banned only makes you stronger. How have you been so polite in the face of such scorn?

 

[jakspyder]

I run my 920 at 4ghz with HT on. steady as a rock at just over 3 years on an R2E. With fans all on low it peaks at 75 under load. With a thermalright 120 TRUE slapped on top with a couple of sharkoon SE's in push pull.

 

[psychas]

ur have good i7 920 chip it does everything fine , with proper watercooling i would say you could do such speeds with lower temperatures, but on air 4.2 ~ 4.3 is more then enough and have lower temps.

edit: ht should be on if not there no point having a chip with ht.

Be interested to see how long the chip/mobo's stable for at those frequencies. I'm having to use 1.38+LLC (net 1.42) just to be stable at 4.2Ghz, but my machine is on and folding 24/7 so it absolutely needs to be 100% stable, so I might be over egging it a bit.

1.331v + LLC for 4.4ghz
1.375v + LLC for 4.5ghz
1.382v + LLC for 4.6ghz

MB is a gigabyte extreme with all the extra cooling on the chipsets plus waterblock (was £250 3 years ago). It was designed for heavy oc. Dont forget is a cherry picked cpu. My other i920 did 4ghz no LLC at 1.300v.

Double post

Seems like Cinebench likes threads

4.4ghz HT on

4.5ghz Ht on

4.6 Ht on
Only ran half way then BSOD lol

Would never expect it to get anywhere near Sandy or Ivy but its better.
Re-sat Alpenföhn K2 Mount Doom with Mx3 instead of Artic Silver 5 temps seem loads better, even with HT on.
