4770k temps bad after wipe?

Alright, to start, I am not home, so I cannot troubleshoot myself. Just want some of what you guys think. This is my first Intel desktop chip (besides some processor like 8 years ago in an HP Pavilion), so I am new to these temps. I do know a good bit about processors, but I am stumped by my situation.

I first had an Athlon X4 760K, then an FX-8320. I finally got the money to get a 4770k. I installed all drivers and uninstalled the old ones (Should have wiped then and there) and then started getting errors on booting (black screen with mouse after logging in) and tried to fix it. I got a good overclock going (4.2 GHz @ 1.25 V) and my temps were fine, only touching 70 C after a few hours of Small FFTs in Prime95. I eventually had to wipe my drive and reinstalled Windows. Got it all setup again, but only during Prime95 with the same OC, immediately went to 90 C+ after a second. At 4 GHz @ 1.2 V, I still hit 80-90 C after a few seconds. I dropped to stock, went past 80 C and almost touched 90 C. That is of course unacceptable for me because I have an H105. I idle at 30-35 C, so the pump and rad are working fine. At gaming at 4 GHz @ 1.2 V, I still only hit 50 C. I just figure I am probably stable because I play long gaming sessions at a time on Battlefield 3/4 and some other games and never freeze or crash. My RAM is at 2133 MHz now, but was at stock 1600 MHz when I had tested it with the wipe before, so the frequency is not the issue. The waterblock is on there perfectly fine and tightly last I checked, and the pump is fine. It happens also when I go to Floating Point Math benchmarks in PassMark and in AIDA64's FPU stability test. Any ideas? The batch is L402B412 (looked everywhere online, cannot find somebody else except for some other language forum) if anybody has information about that or has a processor from that batch.

You will see a difference if using a newer version of Prime95 with Haswell CPUs. I can't remember which version it happens, but my best guess is you had an older version of Prime95 when you were getting 70°C, then after your wipe and reinstall you went with the latest version of Prime95 and now see the higher temps. If you google a bit you can find more information. Again, I'm just guessing here.

In AIDA64, though, when I stressed the FPU before, the temps were much lower. I think I did try IBT and OCCT, not sure, but I will try on the 15th when I get home. I don't remember OCCT getting that hot, and IBT froze even at my seemingly stable 4 GHz the first time, but not the second.

Live check your vcore when you run prime95. For me, it would suddenly draw 1.56v vcore instead of the static 1.13 I set. Only in prime 28, though. In version 26.6 or lower temps are just same as with occt or aida64. If you run over 70 degrees on those, something might be wrong.

Edit: Just read that you got same thing with aidas fpu test. However, monitor your voltage when your temeratures spike. Make sure it doesn't go too much over the 1.2(5)v you set.

My VCore stays at 1.2 V while stress testing, verified by using a voltage meter as well as CPU-Z.

CPU-Z won't change it's displayed voltage, so that isn't a good indicator. Voltage meter should be pretty accurate, though. ;)
But as your cooler seems to be properly working (30 in idle and 50 while playing games is what I get too), I can't really imagine what the issue is, justifiying a 30-40C temp rise in stress tests over games. Maybe check voltages again with like HWiNFO64?

That is why I am stumped. I am thinking about returning it to MicroCenter, but it has been 31 days now and I will not be home until the 15th, so I do not think they will accept a return. I don't understand the issue. When I get home, I will check HWiNFO64. I use SpeedFan, the actual temp reader in AIDA, HWMonitor, RealTemp, and they all show the same.

Oh, when even aida and others show same voltage and temps, that should be alright. I personally wouldn't consider delidding the cpu and removing warranty when you still have a chance of a rma. I'd try to call your microcenter right now and tell them you'd like to RMA. Even if they first say no, stay at it. Might feel a bit uncomfortable but afterall it increases chances of getting help.

The only strange thing is that temps were fine before you changed OS. Your bios doesn't feature a stress test, huh?

I have thought about that for a long while, but I REALLY cannot afford to loose a $340 processor if I inflict damage or it dies within warranty, but voided.

The thing is, I can't OC far. I got a chip that can't go past 4.3 GHz without getting WHEA_UNCORRECTABLE_ERROR. I fixed that on 4.5 GHz by going to 1.4 V and 4.6 at 1.46 V. That was just for benchmarking and I VERY closely monitored temps and only got to 70 C in 3DMark during Physics tests.

Then that's definitely a reason to RMA. The cpu MUST reach 4.4ghz stable.

Ugh. Just hope that wasn't the reason for my 0x124 (WHEA_UNCORRECTABLE_ERROR) 's. RMA'ed motherboard and ram by now and hope the issue was caused by either of those. Well, worst case scenario I'd have to RMA the cpu too. :<
What's your VID, if I may ask? (4x4.0ghz, voltage setting auto, ram on base clock, EIST off, doing a test with prime95 26.6 and then measuring voltage with coretemp)

The warranty doesn't cover overclocking (I am pretty sure). I would only be able to for that on stock. The MicroCenter return policy only allows 15-day return coverage. It has been 31 and will be 36 by the time I could return it.

Even one of mine, iirc, haha. Try to reinstall windows again then? If temps were fine the other time, maybe that fixes it? Otherwise, in worst case scenario you just have to live with that, I guess. When temps stay at under 60 degrees in usual working/gaming circumstances that shouldn't be the issue. You can always run a program that notifies you when temps are going over a certain value in background.

why don't you set your memory to 1333mhz and 1.5v in the bios to see the difference.

i know for a fact that changing mhz on your memory will increase cpu temperature when stress testing.

make sure your setting vcore and not vvrin or any other cpu voltage setting.

ive seen using a particular version of p95 will automatically increase your vcore voltages even if its fixed in the bios.

Wiping again wouldn't fix it, because all I have now is the drivers and some games, as well as benchmarks and temperature monitors. I always have MSI Afterburner open for my GPUs and all CPU cores. Their usages and temps are all there.

I've had pretty amazing experiences with windows installations. Once my pc would only register an action each 10 seconds. Fresh install, no problem. When setting your RAM to 2133mhz, did you increase any voltages? Usually system agent and/or VTT (CPU I/O) need to be adjusticed on oc'ing ram.

Edit: And yeah, like pluke suggested try running it at 1600mhz again? That shouldn't really have impact on the cpu temps, though.

I will see when I get home. I stated that I also tried running at 1600 MHz and still no luck. Voltage was OCed to 1.65 V and the other voltages like system agent were bumped up a little bit, too.

running memory at below overclocked settings will reduce cpu temperature at load. mine has a difference of of 5c on all cores. and to find a stable overclock with good temperatures you need to isolate ram first and not overclock it.

i'd just start from scratch.
easier said than done but if you want the overclock stable and relatively low in temperature you need to cover your bases.
