Oh well in that case - I do respect the TOS here and apologize if what I posted could be considered as "fraud related". Only brainstorming to help - nothing more.

However, it's the word "immoral", in regards to Intel, that I find highly amusing. Very good joke, that was. thumb.gif

Hey everyone,
I am new to this forum and to overclocking. I recently started a new custom build with:

i7 4770k CPU
Asus Maximus Extreme VI
32 GB Dominator Platinum Memory
Corsair AX1200i PSU
Corsair H100i Water Cooler
Corsair 650D Case
Samung 840 Pro 256 GB SSD
2x WD Black 1 TB in RAID 1 Config


I decided that I was going to do a delid on the processor given that I wanted this to be the ultimate overclocking machine. I used a razor blade to break through the corners of the IHS and then used the vice method to finish removing the IHS from the rest of the Processor. This worked well although I did scratch the PCB of the CPU but the scratches were minor, or so I thought. I then used CLU on the processor cores being careful not to get any CLU on the capacitors that are new to the haswell design. Because I was worried about possible short circuits between the IHS and the exposed traces from the scratches on the die I applied a very thin layer of RVT Silcone to the IHS when reinstalling the IHS onto the CPU. I reinstalled the delidded CPU into the motherboard and also used the CLU as the thermal paste between the CPU and the H100i heatsink.

Unfortunately, the computer will not post to the BIOS. When I turned the power on for the first time I made sure that I was watching the components to see if there were any sparks or another visible signs that the CPU had shorted. Everything looked completed fine and normal however I cannot get the computer to post. Furthermore, the OC Panel which came with the Asus Maximus does not show any processor info, i.e. the multiplier is 0 and the BLCK is also 0 but is working given that it shows the CPU temp and the RPM of the fans on the h100i.

The motherboard is showing a Q-Code of 55 which according to the manual indicates that there is no memory installed which is strange given that the memory is uninstalled.

Clearly, something is wrong and need the expertise of those here on this forum. My first question is how do I determine if the CPU is the problem? Then if the CPU is the problem, how do I determine if I damaged the motherboard or the RAM I had installed? If the CPU is toast, then the motherboard would not recognize the installed memory given that the CPU has the memory controller, correct?

Any advice you guys could offer would be much appreciated.

Hopefully this is not a typo and you just forgot to install the memory. So since the memory is uninstalled simple install the memory and fire it up you should no longer get the Q code 55.

Obviously the memory was installed. I'm not that stupid.

Just to give an update to everyone, I did F*&% the original CPU. I went to my local Microcenter and purchased a new i7-4770k and the computer fired right up as soon as I installed it.

Anyways, I successfully delidded the new processor using the vice method. I haven't yet tested it to make sure if its fine but the delid went perfectly. The disassembled CPU looks perfect.

I have one question though about applying the CLU to the newly delidded second processor. I have decided that I am going to install a custom water cooling loop in my new rig which I don't yet have (and actually don't even know what I am going to order given my lack of knowledge on custom water cooling). Given this I might not be able to install the new CPU in my machine until next weekend. Because of this, I am wondering whether or not I should wait to apply the CLU to the Cores until I can get it into the rig and run it so that the CLU can properly cure. I know that CLU will actually dry if left exposed to air and when I do the delid I affix the IHS back onto the PCB with a little RVT Silicone so the CLU would not be exposed to the air but I also know that thermal paste and TIM have to cure by letting the computer run for at least 24 hours so I am wondering if it is a bad idea to use the CLU and then let the CPU sit outside the PC for days? Any suggestions?

You're right about the curing... I'd probably put the top of the CPU back on (without gluing - just place it on top). Keep it in a dry, closed place, maybe just put it back in the packaging.

Then when you've got your cooling sorted out and you're ready to fire your baby up, apply the new paste. I think that's the wisest thing to do..

Lol the fact that this guy said that doing that to intel was immoral. Perspective makes a difference

Just to give everyone an update I was able to successfully delid my second processor! The vice method is definitely best as I was able to remove the IHS and end up with a prefect, i.e. undamaged PCB. I definitely must have scratched one of the traces to the memory controller one the first CPU.

Despite my plans to get a custom water loop installed in the new rig I decided that I wanted to get it running with my H100i until I could get the custom loop in order. Off the bat over 1.5 days of initial testing I am seeing at least a 15 C drop in temps while idling and under load. With the current setup of the H100i I was able to top out at 4.88 GHz which is not that bad considering the current cooling system I have.

Good to hear mate, congrats! 15 degrees drop is great. At what temps are you hitting 4.88Ghz at idle and under load?
