CPU Degraded before my eyes!!!!

Probably more likely the mobo has had it TBH. CPUs rarely die, must be 100 broken motherboards for every broken CPU.
 
24/7 Always on machine used for encoding / gaming for nearly 3 and a half years what is more likely to give up first component wise especially after brutally hot summers where your modem starts begging for mercy.

Motherboard / Cables / PSU, if you have 1 bad SATA Power Connector on a PSU is that a bad sign ?

Are SATA ports on the Motherboard known to go wrong, also is there a reason why IDE mode would be fine yet AHCI provide issues with stability before you even get to windows ?
 
No, sorry. I'd look at getting the RMA process for the motherboard started now though.

But there are plenty of other motherboards out there.

You will likely never get a CPU that good again.

IMO its a result, you get to keep your magic 4.9GHz @ 1.32v CPU.

EDIT - you tried pulling the ram sticks one by one just in case?
 
how do i go about getting RMA?

yeah i tried taking memory out...you can see ive took one of the sticks out.
Am kind of happy my cpu is fine knowing i have a rare one. i posted a few days ago about buzzing sound and i was sure it was from the motherboard. I guess it was an early warnjng for whats to come.

am looking at

Asus Z97 MAXIMUS VII FORMULA

any thoughts?
 
Have ya tried pulling ya battery out on your mobo?, maybe ya just screwed ya bios and it needs clearing.
 
I will contact CCL where I bought it from, just had a look at the RMA process and they need the receipt, and i have no idea where it is. I have reset the bios with the function on the back of the motherboard. I have also took out the battery and connected it sideways and still nothing. Do i need to take it out for 10minutes? I have taken the memory out just kept one in still nothing. I've disconnected the power cables to the graphics card and plugged monitor to the onboard graphics and still nothing.

There is noway that just buy overclocking the cpu (changing vcore and vcache) that it can damage the GPU right?

I have just ordered this...

Yeah pulling the battery out for 10 mins is just a sure way of clearing the bios, i was told to power down, turn off the PSU, hit the power button on your case a few times to drain any power, unplug the mobo power cables then take the battery out and leave it for half an hour. I had a mobo that wouldnt post and i had tried all the normal stuff with no joy, then i tried the above and it brought it back to life.

Yeah i doubt its affected your GPU, i had a PSU blow on me once and it took out the Mobo, cpu and mem but the GPU was fine.

Ah, ok i'll take battery out for 30min and see whats what. I cant see any visible damage to the board or any funky smell.

Tbh it did this a few days ago, and all i did was switch it off pressed the bios reset button on the back and it worked. No sure if it comes with 2 bios's could change it over to the other if it did.

First of mate, prime 95 is a sure way to damage / degrade CPUs extremely fast... It's a tools that should never be run on CPUs like yours. Only older CPUs get along with that software, if you want to test stability just use whatever programs you are going to use IE Sony Vegas or just gaming. If you insist on what is frequently called torture testing (it's called that for a reason) use something like Aids 64 that has been designed to be more friendly to modern CPUs... But still you are better off just running games / the hardest software you are going to be using for that PC as any torture test puts a CPU under a unrealistic load and then adds some more unrealistic usages that otherwise your CPU would have never done.

You do all that Prime, OCCT junk this is what you get!! It totures and destroys. Use Real bench or similar for testing or simply use your PC for your own needs. It crashes adjust!!

All this being said it may well be PSU. Faulty RAM and all kinds of other stuff. Run CPU stock and RAm at XMP and test first.

What older chips is it safe on? and what is it that it is doing that the recent chips cannot stand?

I've only used Prime 95 once for 5 minutes to check load temperatures.

It's nonsense. Prime95 and IBT (LINPACK) are just mathematical solvers. They get chips hotter than most programs because they're efficient.

The smaller the node the more "delicate" an IC is, but voltage and heat will degrade any IC, doesn't matter if it's gaming or Prime95.
 
OP: It sounds more like you just didn't do much in the way of stability testing early on and rather than the CPU degrading you just got a better idea of what the CPU is actually capable of.
 
So.. seeing that OP had issues with the motherboard (presumably temperature related), what is the best way of monitor your mobo while overclocking? and are there any components that we should be keeping a particular eye on? Back in the days when i had an athlon i think the north bridge in particular would get warm.
 
VRMs and NB shouldn't get warm on an intel set up. If you wanted to check, use the built in sensors and check using third party software if your Mobo doesn't have its own but even if you took the heatsink of the motherboards, you will find that they will eat up any power a Haswell would want without issue.
 
Marketing flash. They use to do something on higher power chips with cheaper power phasing configs but most things are 8+2 or 16+4 with half the power of the old chips rather than 4+1.

NB does need a little cooling but even with know airflow around it, the cheapest boards with the smallest heatsinks would be enough to keep the nb a reasonable temp.

The nForce/2 north bridge was certainly very warm. Some people even put heatsinks on the MCP south bridge.
