To RMA or Not to RMA...that is my question?

post #1 of 10
Thread Starter 
I'm a long time reader/lurker, first time poster. First off, here are the specs of my build:

• CoolerMaster CM690II Case (x3 Stock Fans + x1 Scythe Slipstream (KAZE-JYUNI) 120mm)
• OCZ Modstream 600-Watt PS
• Asus P8P67 EVO Motherboard
• Intel i7-2600k CPU
• CoolerMaster Hyper 212+ (Dual Fan/Push Pull)
• (x2) Corsair Vengenance DDR3-1600
• OCZ Vertex2 SSD
• Seagate 1.5TB 7200RPM HDD
• EVGA Geforce GTX 460 SSC

Now on to my problem. When I run my PC at the BIOS defaults, my idle temp in Windows is around 30º and 53º-55º under load (Prime95). No problems there. As soon as I enable XMP in the BIOS, my idle temp in Windows is around 38º and 65º-70º under load (Prime95). If I overclock to a measly 4GHz, temp under load is between 74-79º. Keep in mind, the quoted temps under load are achieved in less than 20 minutes (4GHz temp is acheived in about 2 minutes!). I have both the EPU and TPU switches on the MB in the disabled position.

I've reapplied Arctic Siver a couple of times, making sure the surfaces of both the CPU and the cooler were as clean as could be. I tried using only one fan on the CM Hyper 212 and that didn't change things much at all. I'm sorry if some of you get upset as I'm sure this has been addressed elsewhere. But I've read forum posts until my eyes crossed and have yet to find a viable solution to my problem. I don't know if I'm missing a setting somewhere or if I need to RMA my CPU?

I have been building/fixing PC's for over 15 years, but this is the first time I've actually wanted to do any overclocking. Normally, I wouldn't care if I couldn't OC my CPU, but I bought the K-series CPU to take advantage of the OC capibilities (obviously). I do a bunch of 3D work and my CPU is barely ever at idle.

One last point I need to mention, I ran the stock Intel cooler for about 2 months and my temps were far worse with it installed. Prime95 at stock speeds pushed CPU to upper 70's. OC'ing manually or with Asus Auto Tune Utility pushed temps up over 85º!

Any help at all in this matter would be greatly appreciated!

voltage? typical 2600k will only need 1.33v for 4.5ghz

When running at default clock speed, voltage is roughly 1.232v. With the measly 4GHz OC, bumped voltage to 1.25v. Voltage for DRAM (if not set to auto) is 1.5v.

those voltages are pefectly fine. probably your heatsink. any modifications to it? perhaps it doesn't have proper surface contact with the cpu? thermal compound somehow messed up?
if all else fails, test the cpu on another motherboard and if the problem still persists, you've got a clear window for rma.


edit: totally overlooked your post. go straight for an rma.

Any idea how to do that thru Intel? Past the point of no return with Newegg.

intel has a 3 year limited* warranty on all their chips. give them a call and convey to them the issue and why you can't return it to newegg. they should guide you on how and where to rma the chip from there.

*don't mention that you've tried tweaking the chip or they'll consider the warranty void. just tell them that it runs extremely hot under their stock heatsink & stock voltages/frequencies.

What's your fan speed running at?
Have you tried disabling C1E, Speedstep or whatever they're called, basically any power/noise save features to ensure it's running at full cooling capability.

If you've been over that to no avail, and you've already stated the stock cooler was running warmer temps than it should've, I think an RMA is in the cards.
If the chip aint making proper contact to the coolers, that's not your problem, especially to that degree.
Improper contact to the heatsink, a bad chip that slipped through the net, or something wrong with the VREG's on the Mobo itself are really the only logical reasons you'd be experiencing abnormally high heat from the CPU, with a good heatsink and ramped fans on it.

If you can test the CPU in another rig, that'd be your best clarification. Otherwise I'm afraid the RMA is in order I think.

That's what struck me most. I don't believe temps should be that high under all-stock settings & heatsink. Obvious sign of a faulty chip.

I'm sure you have already checked cpu fan/s are working and heatsink fitted properly and themal paste applied so apart from case fans and case air flow issues i would say RMA the chip. are you getting any blue screens or does the cpu not perform correctly say when running cinebench 11.5 (a good prog to see if all cores are doing their job)

All case fans are running at roughly 1200rpm & CPU fans are maxing between 1900-2000rpm under load. I never get BSOD or lockups. But, when I launch Prime95 Stress test with stock speeds & fan, I have to shut the test down FAST as temp hits 90º in less than a minute. With the CM cooler, I can run Prime95 for over an hour and never top 55º.
One thing I did forget to mention was that when I was installing the CM cooler, upon cleaning off the TIM, I noticed a small burr in the copper portion of the stock cooler. That burr put a small dimple in the top of the CPU as well. Very, very small, and I have seen pics of others with the same dimple on their CPU, but they did not have my problems. If I wouldn't have bought the CM cooler, I would've never even seen the defect as it was covered by Intel's stock TIM.
By the way, thanks to all of you that have responded to my post. I greatly appreciate all of the help!
