On another note the i7-2600K performs on par with 6 core Nehalem in heavily-threaded tasks and is faster in other areas such as gaming.

This is incorrect.

Go back and look at Benchmarks of heavily threaded application 2600k is still slower than gulftown. The gaming part is correct.

It's on par. It also overclocks more percentage wise.

I was waiting for you to post this.

Some of those benchmarks are old now.

Winrar 4.2 which now has full multithreading support instead of 3.8 used in that review shows Gulftown much faster.

If you look at the 2nd pass on the x264 benchmark where is puts a much heavier load on the cpu it wins.

Then the multithread benchmark in cinibench also shows the same thing.

There is maybe 3 benchmarks in there where 2600k is on top by a small margin. The ones where gulftown is ahead show a much larger gap.

I still stand by my statement in heavily threaded work.

So my 3 years old I7 975 just got fried (power surge).

Need help on deciding what to do now (replacement wise).

Since I already have a kickass MB (Asus Rampage III Extreme, extended) the most simple way would be to get a new 1366 CPU. The problem is they are extinct, the only one available without much hassle is i7-990X with a $1000 price tag.

Should I just go for it, or completely re-haul whole system and get some new MB+CPU? (if so, what's considered good nowadays?)

Buy an i7 920 for ~ 100$ and overclock it to 4.2Ghz with HT on and jump on the boat and wait till Haswell

Unless you find someone to pay decent money for a 1366 board.. I would think that market is dwindling now, though.

Jump on the overclocking boat OP. Just jump.


ps I'm drunk. And still at work for another half hour. but really you're worried about someone abusing a ~$100 i7? You realize a $1000 chip was destroyed in your own home right? And you're worried about some reseller? I think this thread made my day.

I know there are some that just won't overclock for reasons they cannot defend, but you are an entertainer.
This canadian with the superman avatar. you listen to him.

That looks like sidegrade. Wait until Haswell 2013 or grab a cheap mobo and a 2600k ,,,,,, or haswell,, those are you two options... that 975 is good chip. Look at me, and I aint complainin, I love my rig.. thank you..gg

I wouldn't spend cash on a CPU unless you are certain that the motherboard, video card and all else are verified good. Even then you can't be positive that the rest wont fail after a short time of use.

Have you tried another known good CPU in that board? until you do, I would opt for a new build with all new parts except the case. And have your tried you video card and other parts in another system?

FFS, i can't OC 920 to 4.2Ghz
I use air cooling only.

I don't have access to another good 1366 CPU (i have to order it from overseas)

But i did try the one that "died" in another motherboard with all different components (Video, PSU, RAM) and gotten same results (no post).

This tells me that there is a pretty good probability that the CPU is indeed dead.

Another vote for an OCed 920 until Haswell or until you get sick of it. There are plenty of them out there which haven't been driven into the ground. At 3.8 or 4.0 GHz, it will be considerably faster than your 975 already (assuming you weren't overclocking it.. maybe i missed that part), and you can hit that on air and with a very modest voltage bump. IIRC, mine hits 3.8 at default voltage, and isn't really that special. So, ~$150 to replace your fried chip, much of which you'd be able to recoup by reselling it if/when you upgrade again, seems like a good choice.

If the CPU was indeed killed by a power surge then the rest of the components between it and the wall are likely dead too.

However if you're super confident that the board is still good, get a 920. You *can* take it to 4.2 on air.

Otherwise get an Ivy. 4.4Ghz is a given on anything but the stock cooler (and might be on that - haven't tried) and it's significantly faster per clock.

I went with 975 because of high base speed (without overclocking).

And no, i cant' OC 920 to 4Ghz because i run everything on air. (though i did OC 975 a bit, up to 3.8 i think)


Someone already posted a con against getting a used 920. There is a 99% probability that previous owner ran it into the ground.

Anyway, i'm still undecided 🙁

Someone raised one questionable issue about a used I7-920 and then you state that there is a 99% chance that a used CPU has been abused-that is just plain silly. Just buy a used I7 from the for sale forum,( of course from a long time Anandtech tech member with good heatware) and your heart will go on singing.
 
4 GHz on a D0 stepping chip, regardless of model number, is usually doable on half decent air cooling. Of course it does depend how good the chip is, but most will do 4 with decent vcore and cooling. Keep in mind that ocing a multiplier locked i7 on 1366 is a bit more tricky than an unlocked ivy or sandy, as you have to adjust BCLK, QPI VTT, and sometimes memory and uncore freq. as well as just vcore.

That said, its pretty easy to get a hang of. What is your cooling right now, which air cooler? Good air coolers can get 4.2-4.3 with good D0 or gulftown based chips. Sometimes even farther with a gulftown.

I use Zalman CNPS10X right now

So far after reading up on the current state of things, I figured the best bet is to get a 1155 MB and a i7-2700k (i run on air, and heard that 2700k it overclocks better than 3770k)

Another option could be i7-3820

What you think?

Didnt you just say you couldnt justify a socket 2011 build :hmm: Get a 2600K, exact same thing as a 2700K but its 60$ cheaper.

Yeah, but it doesn't tell you that the board you have isn't dead. Or damaged in some way. (I had a power surge that killed a mobo - at first, it seemed okay - just one of the DIMM slots didn't work. Then it was two. Then it started blue-screening a lot... it took 3 months to die. It was horrible. A slow, lingering death, full of pain and suffering. Nobody should have to go like that.)

So you can't really sell it. Ethically, anyway. Except maybe as a "non working pull" but then who'd buy it?

coworker had a similar situation. power surge and his LAN stopped working... then it was some of his memory ports... then eventually it wouldn't POST.

tangent: why is winrar used for benching? do people really use it that heavily? winrar has probably used less than 5 minutes of processing time in the last month on my computer.
