Think I fried my 2500K :'(

[Nick89]

Nor me but never had anything like this happen so I am worried, what does the vcore offset actually do cause as mentioned I set it at +0.5v (stupid glitchy mouse control in efi bios ) so what would that actually mean for the CPU as mentioned it wouldnt boot anyway so was only running like that for a minute

Just an FYI, I never use mouse controls in the bios. Only the keyboard. Can't go wrong with the keyboard.

Also, unplug the PSU then take the battery out. That way there is no power to the board at all.

My first 2600K died in a similar fashion. If the new motherboard doesn't solve the problem RMA the CPU, it's possible they give you a new one.

If I had to guess I would say the motherboard.... If it where the CPU.... you would probably just get a No Post/No video. But since you get to the windows installation....sounds to me like something is damaged on the motherboard somewhere. I would definitely try the motherboard first since you have tried most of the basics that everyone else has suggested to you.

Think it's bad news, replaced mobo, installed all components went to load Windows and bam BSOD, the same one left CPU at stock and put 1.35vcore through her and loaded Windows without a hitch the first time. Looks like it has degraded because of the extra voltage put through it, the only real question now is how long it will last. The SB chips are notorious for degrading when they receive too much voltage, sometimes they can run for months and other times it has been a matter of weeks/days from when the degradation starts.

Am in a fresh Windows install so am going to start doing some stress testing at stock and try and get it lower than 1.35vcore to see how bad the situation might be, though tbh I think this 2500k's overclocking days are over, RIP baby

2500K is $149 at microcenter atm...

 

[FreedomEclipse]

Pitty you cant RMA a CPU while its in that state too. you are stuck in a half dead like state and you never know when its gonna cop out.

Not bad if shipping to the UK doesnt kill it

Before ordering further hardware or RMAing something (takes time, stamp costs, etc.) you could try to check the system with priority on RAM.
As you have only a DVD-drive I propose the Ultimate Boot CD. It has lots of stuff like partitioning, etc. but also many hardware test suites. Let them run for some time and pour another glass ;-)

I have previously tried ALL RAM sticks seperately and in different slots with no luck, tried booting with onboiard and only 1 stick of RAM plugged in and absolutely nothing else and still no joy, tonight everything plugged in, give her some vcore and bam booted straight up, as I mentioned thye symptoms I have SB chips are notorious for developing if you give them too much voltage, luckily (well not for me) it doesn't happen as much now as when they first came out as overclocking SB has come on since and people can still get 4.5-5.0 out of them without pumping them full of voltage and degrading them.

Freedom you are right, I am stuck in limbo, just how far into limbo I am I do not know. Good thing is even at 1.35v it's idling at 24c and running IBT never goes above 40c, bought some MX-2 today and really my temps are FAR FAR better than the temps I had previously with Arctic Silver

 

[scooper22]

there are further tests for CPU (int/fp) validity and stress resistance on that CD. Or HDD-Tests that go through the SATA controller on the SB.
(Also, sticking one RAM stick in at a time is not testing the stick for vaulth-free-ness. A RAM test covers the whole address space on the stick and is usually located in the hours runtime)

Might aswell bite the bullet and grab another CPU

 

[NdMk2o1o]

Am tearing my hair out,

The CPU is actually at 1.135vcore not 1.35v as I thought and it passes IBT at that voltage (actually reads 1.044-1.055 in Windows ) So that's my theory of it being the CPU out of the window, I mean it still could be but now it doesn't make any sense at all.

RAM is running at 1333, going to leave everything else as is and run the XMP profile and see what happens

IMO either your house or room is retardedly cold (was 17-18'c in my room a few nights ago - my coolant temp went down to 28'c) or the temp sensor on your CPU is borked. like my 4870 was when Sapphire returned it from RMA.

My 2500k alone idles at around 30-35'c. Im thinking its borked. I used MX-2 for a long time on CPUs and graphic cards and they never dropped temps that drasticly unless the room was freezing.

-----

I'll probably get trolled for saying this, but id just do whatever i can to finish the CPU off then just RMA it and say it just stopped working one day.

 

[eidairaman1]

This is a very Hard lesson learned indeed, wisest words, Everything is like a box of chocolates, you never know what your gonna get.

Next time, Up the CPU a little bit and run it for a week with stress tests daily, keep eye on temps, voltage, cooling. Record it down, then up it a lil again n so forth.

 

[NdMk2o1o]

Up the CPU a little bit

I didn't mean to pump +0.5v into it :shadedshu

So after trying XMP (1600mhz) can't get the system to boot without BSOD even setting 1.65v for RAM and trying from 1.135vcore up to 1.32, it just wouldn't go.

Might be the RAM, chances are it's the memory controller, hirens boot CD here I come

On a sidenote, it runs lovely at 1333 RAM and low vcore, fast aand solid, anything else and it just won't do it

 

[eidairaman1]

Try the Factory speed of the ram without XMP, aka force the settings themselves.

So set 1600 and sub timings manually?

 

[eidairaman1]

yes and the voltage that is factory for that ram.

Tell u truth I dont like XMP or anything like that rather do it myself.

Don't forget you may need IMC volts too. With XMP off that will drop to stock. Most XMP profiles will add some here.

I will try, 1 question should the vcore have an effect on running a higher/tigther RAM timings? as I have it a 1.135v do I need to raise it when I up the RAM as the mem controller is on the proc?

Not typically, that's why I mentioned IMC voltage.

Thanks man, missed your post while replying, what kind of region should the IMC voltage be in?

 

[sneekypeet]

it is different for every kit really

If you are having issues at 1600mhz ram speeds, bump it one or two notches from stock, shouldn't take a ton of volts to get it stable though, so if it isn't responding well, don't keep pushing the IMC

I don't have my board fired up to see the voltage, but iirc 1.2V is top end, as in you really don't need that much.

what else might the IMC voltage be listed at

 

[sneekypeet]

googling the board...brb

 

[eidairaman1]

TBH I dont overclock ram at all, leave it stock, CPU and vid card are what i focus on.
