Can we get pics?

Ket, here's my $200+ contribution to the forum. As you can see in the pic, the cpu die is still attached to the IHS.

[pythonse]

What settings are you using? I can't get mine stable at 4.8

change as little as possible in bios..no need for most of the setting to be modified to get it to 5 ghz and stable
so off the top of my head i have
cpu ratio at 50
turbo boost 255,255 and leave the last one at 1
then i set my ram at 1866
upped the voltage to 1.6
upped the voltage on my cpu to 1.4
saved it to profile and booted up with 1.61 bios intalled, with my 570 gtx im getting over 33,000 on 3dmark 06
i run core temp,precision pro,and asrock extreme untility on the desktop to monitor settings,temps....ill bet ur stable at 4.7 with just upping ur cpu ratio in bios to 47? and nothing else changed? what ram do u have?

what happened to ur chip? u burn it up?

That pic should go in some kind of hall of fame its pretty awesome Guess that settles my last hope for cooling my hothead 2500k down though, its just a hot mofo. Hmm... maybe I could run the chip just for like 2 mins though with no cooling on it at all... enough to let any solder spread over the CPU die that maybe isn't being covered properly.

[pythonse]

so he fried it?

[Ket]

Dunno, but that has to be the first naked 2500k pic on the interwebz

Ya, not sure how. I was using recommended voltages, and temps where really good. Just went to turn my computer on in the morning and it wouldn't post.

[Ket]

Ouch. I guess that chip must of had a weak IMC or something to die like that.

why didnt u send it back and have it replaced?

[Ket]

Sometimes destruction is better therapy

The guy working at the store was telling me that intel can now detect whether a cpu has been oc. and will deny warranty. Any truth to that? I should have asked that before I decapitated it, but as Ket said, "sometimes destruction is therapy"!!!!!

[Ket]

Intel probably can tell if its been OCd, but the guy in the store was full of . Intel sell the K series full well knowing the chip is unlocked and will be clocked by OCers and price the chip accordingly to cover any RMAs. In a nutshell, unlocked chip, intel know its going to get OCd, yet the chip is still covered by a 3 year warrenty. Dude in the store is clueless or just couldnt be bothered with processing the return.

So, this new processor batch# 3049A355 absolutely sucks! Last night I had it running 4.6 @ 1.36v. Played C.O.D all night. No problems. This morning I went to fire up the computer, and just got the blinking cursor. So, after playing with it for over an hour, I can get it stable at 4.2 using 1.32 v. But anything higher, I get the blinking cursor. Now is it a poor cpu, or is my mobo killing these chips? All other voltages have be let at auto.

[Ket]

I noted even when I set 1.32v with fixed vcore there would be spikes of 1.4v+ according to realtemp.. or was it coretemp? one of those anyway and temps would spike with those voltage spikes but CPU-Z and AXTU remained at a constant voltage of 1.32v so theres no direct evidence to suggest the vcore spikes are due to the board. If I had to guess I'd say if the spikes are legit and not a sensor anomaly the spikes are being caused by something to do with turbo voltage.

[piquadrat]

I'm hearing more and more often about the blinking cursor issue. The same scenario. The processor is stable as rock in operating system but next boot and you get blinking death. I can remember one particular case when replacing the mobo did the trick. But don't know which board was replaced by which. Maybe someone experienced that issue, resolved the problem and could share a solution?

[mean6]

Just wondering, if I should trade the chip for another, or the board?

[Ket]

I would return the chip. 1155 boards have more or less zero to do with how a SB chip OCs, its either a good chip or its not

[mean6]

Still playing with this chip. Anybody try 1.62A bios. I tried it out and found it to be really buggy. The offset voltages seem to be way off compared to the numbers I got with 1.61. It also has the spread spectrum bug as in previous versions. In the end, I went back to 1.61

Just an FYI, this won't do any good. Melting point of solder is ~180C. Your chip will reach Tj and shut off before any solder melts. You could use really short bursts of heat with a blow torch to do the job, although that still risks the possibility of burning up your chip.

The thing is: the chip seems to be perfectly stable (in the cases I have read about) but after powering down next boot ends with blinking cursor. That could be motherboard issue. Maybe some setting/bios combinations.

I didn't think 1.62A was that great either but it didn't have the spread spectrum bug and neither has any UEFI since 1.6A I would suspect something else is going on there.

[mean6]

I just noticed that when I had cpuz open the bus speed shown was 98 rather than 100. I went into the bios, changed spread spectrum to disabled, and it wouldn't boot. I remember those exact symptoms from earlier bios'.

[Ket]

I've tested UEFI 1.6A, 1.61, 1.62 and currently testing 1.64A, none of them have the spread spectrum bug on my Extreme4. Downgrade to UEFI 1.3 (DOS version), load UEFI defaults then save and exit, then re-update to whatever UEFI you are using.

[mean6]

I am getting some weird stuff happening. I spent all afternoon, overclocking and trying to stabilize my setup. I had it prime stable for a couple of hours. I shut the system down, and left it for about 45 mins, turned it on and got the blinking cursor again. So, just for kicks, I loaded uefi defaults, rebooted, then loaded my saved profile, and it booted straight into windows. I think there is something screwed with this board. Might explain why my other chip went on me. Any ideas????

[Ket]

Use stock settings then see if you still get the blinking cursor. If you don't, seems unlikely it would be the board.
