what are you other settings?

did you just leave everything else on AUTO?

RockGod213 did you nick the pcb?


RockGod213 did you do any testing on the CPU before you delidded? Before delidding its always a great idea to over clock to see what you are working with.

I have seen some people get some very low quality IB cpus in terms of over clock performance and thermal performance.

Hope you are able to tune your BIOS to get it right.

Because delidding can cause CPU IHS to shift ensure that H60 CPU block is properly seated. It's possible this can cause instability.

Also check to see that your ram is stable as it seems you have it overclocked to 1866. This is sometimes the underlying cause of CPU instability which in some cases users think it's the CPU and unknowingly up the voltage when, really, it's the ram.

Check your temperatures when stress testing and make sure CPU isn't throttling.

It's also possible you may have hit your wall but that is unlikely. 4.5GHz shouldn't need that high of voltage. I could be wrong but yours is definitely a first if I am.

I am 100 percent sure I did not nick the die or PCB at all. There's not a single mark on the PCB or die. I understand that a failed delid might cause a memory bank to stop working or something like that but why would it make the chip clock badly? Needing more vcore to sustain an overclock doesn't seem to be something a nick on the die could cause. I would think it would either cause some part of the CPU to stop working or cause the whole thing to stop working. Maybe I'm wrong.

IHS does not shift at all when the block is seated. Ram is totally stable and I have set it to stock just to make sure that wasn't the problem. It wasn't. The temps seem fine to me, other than the CPU package being 7 or 8 degrees hotter than the core temps. Cores are sitting at around 65 with the 4.7 ghz overclock at 1.5 I'm at now. I tried taking the CPU out again, cleaning everything with alcohol just in case there was some paste or something and it's still doing the same thing. Rock solid at 4.5 but beyond that I either black screen or have instability.

Typically yes. But it can also nick a trace causing very minor instability. Its more than plausible. not saying you did, but 1.4v for 4500MHz seems atrocious. It could also be wrong settings in BIOS. Thats why its recommended to test OC before a delid.

One way to find out is to lower everything to a lower OC or stock setting prime it and see if its stable, if so then its atleast fine.

Like I said, it's fine at stock or anything under 4.5. Why would it only show up at higher speeds? I'm thinking it's just a crap chip, but it's still sad because the 2500k I have does 5 ghz. 4.5 is a downgrade for gaming mad.gif

If it really just needs 1.4 at that speed, and nothing else is wrong then it seems you just got the bad lotto ticket.

My recommendation sell it and try again, or stick with that sandy. a 5GHz 2500K is more than enough for gaming.

Can't sell it because I got it through Intel's deal. I had one shot and got dealt a bad hand. I could sell it, but I'm not one to break rules. I'll just sell the 2500k to make my money back and deal with it. I guess I'll know better than to trust the silicon lottery next time haha.

Most likely a bad chip there were people on this thread that needed similar volts for 4.5ghz
