Bad chip? Keep or exchange 4770k

I'm new to overclocking, but have spent considerable time researching prior to building this pc. As I am still within my window to return my chip to my local store without questions, I'm wondering if I should keep this chip or go back and get another. To me, the voltage seems a little high for these gains. Thoughts???


After running steady at stock settings for 8 hrs in Aida 64, I have begun to play with my OC. I was able to run 42x at 1.25v (can not boot under 1.25) for 8 hrs in Aida 64 as well. CPU temp did not exceed mid 50s and my highest core temp (core 1) was 65 deg C

44x 1.28v-1.3v CAN NOT BOOT WINDOWS
44x 1.32v CAN LOAD WINDOWS - have not stress test yet

43x 1.26v CAN NOT BOOT WINDOWS
43x 1.27 CAN LOAD, have not run stress test yet.

Specs:
4770k
Asus Maximus VI Hero
corsair h100i
Radeon 7750 gpu (taken from other computer while new one is being shipped)
gskill 8gb ram

UPDATE - CAN NOT RUN 42x at 1.25v stable for more than 15 minutes in Aida64

Thanks in advance

Hi,

Lets be honest, it's not great is it. From having a look at other peoples results it seems like yours is poor (although there are worse out there). Up to you what you do with it at the end of the day though.

Probably going to exchange the chip. What thermal compound do I want when reseating the h100i?

pretty bad chip. China here 4770k all made in malay(I'm chinese), i was told in us 4770k are made in Costa rica and most of chips in us are better than china. but it look like it isn't as i thought.
I recommend you exchange this one.

i think an average 4770k runs 45x at about 1.3V. Mine runs 42x at 1.15V, and 45x at 1.3V(in Prime95 for 30m). But it's not even a good one, here in chinese forums i saw a lot 4770k runs 45x at 1.25V or even lower.

I wonder how can the temp never exceeds 65 deg C under 1.25V. mine exceeds 65 deg C under 1.145V at 37X...

I think it's fraudulent to swap chips cause they don't overclock as well as you'd like. That leaves that chip for someone else at best. At worst your costing the company money when their is absolutely nothing wrong with the chip. If you can get away with it and it's the type of thing you wouldn't mine someone teaching your kid to do for example. That's your perogative.

That said, we all hope for the best but u can't always win. Is all that really worth the trouble for a "chance" at getting a better clocking chip. Could be worse. Then what? Do it again?

Fwiw I had an above average chip that hit the ground and broke. I probably could have pulled a fast one but I sold one of my monitors and bought a new one. Like anyone, I hoped it would perhaps clock better than its forefather.

Quite the opposite. Delidded with a heavy duty watercooling setup it takes me almost 1.5v for 4.6 stable.

Mind you temps are feasable but most people can't run at those voltages so id imagine it would do 4.3-4.4 under normal circumstances.

Haswell is just a bad chip for enthusiasts. Taking nearly a half a volt for 700 MHz is ludicrous but not worth my time to consider an exchange.

Buy a better cooler. Add some more voltage. Or call it a day. Apart from ego the difference is largely trivial.

Most of us have to swallow that pill. A 4.8 chip even with a delid and the best cooling is rare at best.

Forgot to add, this is all with 12hr prime minimum. Obviously with a less stressful test I can manage a tenth or two less. Still 1.45v is the best I have managed over 4hrs of prime at 4.6. Considering I can post 4.6 at 1.25, goes to show you the difference between posting and being prime stable.

By pretty bad u mean average? Even that is a stretch since he hasn't found his upper limit. He's still using the far low end voltage wise and if his temps haven't even surpassed 60 how can that be much more than an assumption?

I have an similar bad chip. Need slightly over 1.3V to get it to 4.3 but decided to stay at 4.2 @ 1.2V and had to decide, too, whether to exchange it or not. I decided not to and kinda regret it now.
