Phenom II X6 1055t Vcore, it's normal?

[jbnetosilva]

Hello guys! I have the following question: I have a Phenom II X6 1055t and a mobo Gigabyte 78lmt-usb3 rev. 6.0 (I know it's not a very suitable board for overclocking). I've done some tests with a relatively simple overclock (2.8 GHz to 3.4 GHz), however, I realize that when doing a stress test with the prime, I realize that CPU vcore reaches 1,512 V (in cpu-z and in AIDA ), And this happens even by limiting Vcore in mobo's BIOS to 1,452 v. My question is: is this voltage of 1,512 in Full load harmful to my cpu?

PS: Despite this voltage, the system with the overclocking remains stable and the cpu with a satisfactory temperature, since I am using a Hyper TX3.

And sorry, English isn't my first language, it's a working in progress, so feel free to correct me.

The vcore is somewhat dynamic in that the system will regulate it as needed. Plus, not all apps are that accurate. Using AMD Overdrive to check vcore?
I believe AMD used to set a recommended max of 1.5v for the Phenom II's vcore. But many folks that OC'ed in "those days" went higher. That board should be fine at that setting if temps are OK.

I also checked on AMD overdrive and it showed the same vcore, but only when the cpu is full load on the prime95 stress test. For me (considering that I'm a newbie on the subject of overclocking),that would not be a problem, because the heaviest use of the cpu would only be in games, where the six CPU cores are rarely at 100% usage. As far as temperature is concerned, at full load it reaches 57ºc.

Your temps are great. And I wouldn't worry about the slight Vcore jump. My PhII X4 965 @ 4.1GHz has a vcore of 1.475. But it jumps to 1.500v occasionally when stress testing. Your PhII x6 1055t has turbo boost, meaning it kinda takes over when less than 6 cores are needed and auto boosts the remaining core(s). You might want to disable turbo boosts when going for your max OC so it doesn't interfere with your settings.

Btw, do you have the 95W version or the 125W version of the 1055t?

I have the 125W version.

Good. Using the stock cooler? Seems like those are exceptionally good temps if using the stock cooler.

I'm not using the stock cooler because I realized it was getting high temperatures, even without overclocking. Now I'm using a Hyper TX3 Evo, which, even being a cheap air cooler, has satisfactory performance.


Also, I started overclocking tests after I bought the TX3, since the temperature was so low without overclocking, I decided that maybe it was time to try 😀

For an inexpensive cooler, the TX3 isn't bad. As long as you stay within its limits. I have one on an older build right now. Thanks for the feedback.
