Seems I Have A Poor Chip

[bmw477]

I followed Chino's overclocking guide and successfully booted at 4.7 with 1.35 Vcore. Highest temps during stress testing were 90. My problem is if I drop the voltage at all from 1.35 then I BSOD after seconds of Prime95. I realize I just may have a poor chip but still thought I would ask you more experienced peeps if ya thought there was anything else I could try at 4.7 with lower voltage. Is reaching 90 C in Prime95 an indicator of a risky 24/7 overclock?

That seems a little high considering your on water cooling.Im at 4.6 with vcore at 1.200 and my temps max out at 63c under load.

Do not forget that P95 stresses your CPU usage to 100%. In normal day use, you wouldn't get close to that leve of usage. What I'll suggest is that you open a temperature monitoring program and use your PC with that overclock during one day and monitor the temperatures. See how high they get. There are only two ways to compensate a not so good overclocking chip: decrease the overclock or get better cooling.

On paper, the TT Water 2.0 Pro is only a few degrees cooler than a D14. Maybe 3-5C. Bmw477 is getting higher temperatures because of the higher voltage he needs for his overclock. A 0.15v difference makes a huge impact on the heat output.

Thanks Chino. That is kinda what I was thinking. I will play my normal games for a day and just see what kind of temps I get. I was really hoping to be like some others and reach 4.8 with around 1.3 Vcore, but obviously it just ain't gonna happen. Will post back what my gaming temps are on 4.7. Thanks again for the reply.

Those temps do seem high for that overclock and Vcore voltage.
Hyper PI 32M at 4.7GHz with 1.350v maxes at 72c for me with a push/pull H70.
I would look at your case airflow and fan configuration.

[bmw477]

Thought I would throw in my fan setup. Maybe you guys would see something I'm not seeing. I have a CoolerMaster Storm Sniper case with a 200mm intake fan on the front, a 200mm intake fan on the side, a 200mm exhaust fan on the top, and 2 120mm fans in push/pull across the radiator of my TT Water 2.0 Pro.

[NemesisChild]

Very similar fan configuration as with my HAF 922 and H70.
Is the TT Water 2.0 Pro mounted on the inside and are the fans in an intake or exhaust config?

[bmw477]

Yes, the rad is mounted on the inside of the case exhausting out of the back.

Maybe a Re-Grease is in order.

When I was at 4.7ghz, (1.33 fixed vcore) on a Raystorm with an RX360 rad, it would prime as high as 87c depending on the room temperature. Remember, this is a 3770k, which can vary in temps not only due to the vcore, but also due to how not-so-good to really-bad, the TIM is globbed on under the IHS. Some of these chips get really hot, as mine did until I delidded it. The Raystorm setup got me about 8c over an H100, and delidding and using Liquid Ultra got me a drop of over 20c more. Yea, my chip primed around 95c on an H100 at 1.33 vcore. I don't think his temps sound all that odd, based on my experience with mine.
