My CPU just got fried I7 975 Extreme. What now?

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?)
 
Sell what you have (Mobo) and go for Socket 2011, it seams you have the extra cash to spend 😉

You can get a socket 2011 Mobo + Memory + Core i7 3930K for the same price of Core i7 990X.
 
Are you sure the mobo is OK, if it fried the cpu the mobo would be suspect also. If it is OK and you want to keep it the for sale forum would be your best friend. Plenty of I7's on there.
 
Did you fry the motherboard or CPU? The motherboard is usually the culprit. If that's the case get a LGA 1366.

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.
 
On the topic of power surges, do you have anything along the lines of surge protection?

The last time I had a power surge zap something (the motherboard) was about 1999 before I got a 4-way with surge protection.

Well, it seems ok. Leds are working, etc 🙂 Tried the CPU on a similar 1366 MB and had same results (no post)

I can't justify getting a Socket 2011.

I most resource-demanding stuff I do is gaming, which is pretty much the same on 1155, no?

What's the current state of things? Are there new processors on the horizon that are worth waiting for?

It looks like the CPU is fried.
PC won''t post and a red Led "CPU" is constantly lit up on the motherboard.

I tried another (working) MB with that processor and get exactly same results (no post) so I deduced that the CPU is dead.

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?

Why can't you get a used CPU?

please don't spend $1k on a 1366 CPU...


edit:

these CPUs are not extinct. I see them on Amazon and Buy.com from their affiliate vendors which are perfectly reputable for your purposes and come with a money-back guarantee to quell whatever nightmares you might have about not going through newegg.

They are hard to find and still expensive ($200-$400 for 920 / 960)
 
They are easy to find and priced competitively with what the market will bear.

Keep in mind you were prepared to drop $1000 on a marginally faster chip. If you want to migrate to SNB we'll support you, but don't delude yourself on the availability or cost effectiveness of Nehalem in order to justify the move.

I won't go for 920, because it would be a severe downgrade.

And for the price of 960-970 i could get a new 2700K setup. No?

Or maybe i should just wait for Haswell 🙁

No, for the price of a 960 you could get a similar SNB CPU, not a whole setup.

$308 shipped.

Are you afraid to overclock the CPU by 5% to match your 975? Most of these do 4.2 GHz with no trouble. If you aren't into overclocking, why would you waste the money on extreme edition parts, $300+ board, etc in the first place if you were not going to make the most of them?

[I don't understand . .. if someone invests in an extreme processor and other parts . . . . why it wouldn't seem to make sense to invest in a UPS/battery-backup system with "square-wave" power and isolation from the source of thunderstorm-misery . . . . This is like health insurance . . . . or -- any insurance .. . . Running off the wall-socket is almost like driving your Escalade without coolant or oil . . . . ]
 
What will you run while waiting for Haswell ?

I wouldn't spend extra for 2700K... 2600K will perform the same with a very mild overclock..


If you want to push it to 4.5 and beyond, the 2600k should still match the 2700k ...
 
How is it a severe downgrade? The 975 doesn't OC any better than a 920 (max around 4.2 Ghz) and it's the exact same CPU, and you can find a 920 for $100-$150 if you look on the BST forums.

Don't bother with the 960/970, you don't need 12 threads for gaming, it's a waste of money.
 
I'm not convinced he overclocks. He seems alternately concerned and unconcerned with value.

I think he just sorted everything by descending price and ordered.


960 is a quad btw. 970 is a hex. 975 is a quad.

Sorry, I'm sure you know what I meant

I think so too, even if he doesn't overclock right now, it's so elementary. Buy a used 920 for $120 (there's plenty around), set BCLK to 160 and forget it. That's 3.36 Ghz without touching anything else, and it's virtually the exact same performance as the 975 at 3.33.

Does this question really need to be asked when you can get a kickass Z77 board and a 3570k or 3770k system for half (i7) or less (i5) the cost of that CPU?
 
Tough decision. I would be uncomfortable getting a used 920 myself. Who knows how hard its been pushed and for how long. It could already be degraded by the time you get it. I'd get a new one if you go this route.
If you want to sell your old stuff off, test it with another CPU first. Borrow a CPU or something to test with, otherwise your board might be bad and you won't know until your buyer complains.
If you sell it off, i'd go with the 2600K in an instant. You get a way faster CPU that clocks like it was blessed by Chirst, and it has 8 threads to push games like BF3 to their max performance.

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 🙁
 
Ivy is the easy choice here.

Sell that board and get a 3570k Plus a nice Z77 board. (If gaming, general use, etc)

If you need hyper threading spend the extra to get it. I personally don't think its worth the extra cost.

Um no!

You can find plenty of 1366 cpu's you just have to look for used parts!
Craigsist,Ebay, For sale on this forum.

Where are you located?

a 920 has the same overclocking headroom as the 975 how is that a severe downgrade?

Also i've seen used 920's for $150 infact i'm selling one for that price also from a spare machine I just got rid of.

And this chip was at 3.8 @ 1.25vcore its whole life!
