I recently purchased a NIB 2700K SB as a replacement for a 2600K that was beginning to show signs of degradation. When the new 2700K showed up I set my Motherboard to factory defaults (Not OC'd) and proceeded to swap the chips.  After installing the new 2700K it refused to post could not even get to the bios. I place the 2600K back in and the system fired right back up?  I have never had a chip fail.  Am I missing something?  Shouldn't a 2700K be a drop and swap solution for a 2600K?  Did I miss a step or something? I cleaned and installed using proper thermal grease etc. and am build all my own systems but I'm at a bit of a loss on this.

 

The vendor I purchased this through via Amazon is willing let me send it back to them and that they would test it.  If it checks out (they find it to be operational) then they will charge a 25% restocking fee because it's now an open box item which I understand; If it's defective they'll refund my money.  I really feel at their mercy which makes me a bit uncomfortable.

 

Got any suggestions?

 

1) Did you double check that the proc. is seated correctly on the mobo?

 

2) Do you have another mobo you can test on?

 

3) Try to boot with one stick of ram, then the other, it could be bad ram. 

Also try updating your BIOS.  The 2700k was not available when the initial 6 series motherboards launched, or even when the revised boards came out.  It's very likely that your board doesn't know what the chip is.  Also check the underside of the chip for debris on the LGA pads.

Good Advice Thanks..

1 Yes Twice

2. Unfortunately no not with the right socket

3. Wilco; right after I try updating the bios

Good Advice as always I knew I was overlooking something my board is a ASUS ROG Maximus Extreme IV Z and your right I dont think the 2700K was out when it shipped.  I only updated the bios initially So I'm off to try that and will post results

I know you said you are running at stock settings now, but if you have an OC profile saved make sure you copy down those settings. If you Flash the BIOS any saved profiles you have (if your MoBo supports that) will be erased when you flash. I spent hours (days) tweaking my OC, saved the profile, flashed the BIOS, and poof, everything was gone. Just something to make note of.

Thanks Jordan I saved my profile as per your advice and thanks TechguyMaxC the bios indeed was the issue flashed it to the latest and it powered right up!

 

Now comes the hard part...trying to decide whether or not to keep this as my core Sim computer or pass it to the kids and keep the Haswell that's en-route?  I suppose if I get a good Haswell chip that can clock at 4.4-4.5Ghz without melting down then I'll keep it?  At any rate it will be interesting to see how they match up.

 

Thanks again for the solid advice which saved me time, frustration and money.

If you can get that 2700K to over 5GHz it's probably worth keeping since Haswell is a total crapshoot.  You could hit 4.2 or 4.8, depending on how good your chip is.  At 4.8GHz Haswell is faster than Sandy Bridge at 5+, but you'll be extremely lucky to hit 4.8GHz with Haswell, even if you de-lid. 

My thoughts exactly, from what I've read your right a total crapshoot sums it up nicely.  I've got all the right gear MB, RAM, PSU, Cooling etc. but it won't mean squat if the chip wont clock to at least 4.5.  I've got the 2700K at 4.8 right now I won't push it any further until the Haswell system shows up and I can see what it will do.  I ran my 2600K at 4.9 for the last two years and when I saw all the reports of Haswell running hot I ordered the 2700K as a fall back since the SB's are so easy to OC.

 

I'm not certain that the issues I was having were do to the degradation of my 2600K or not but my system would hang at times loading the OS and reboot every so often for no apparent reason. The Mushkin ram I was running passed every test I threw at it so I chalked it up as cpu degradation from OC'ing but I really can't be 100% sure.
