So in the picture the 49 degrees?

Yep.

This is the number that AMD uses to determine the chips maximum TDP, and is the only physical number available. Core temperatures use an equational offset calibrated to celsuis but "immeasurable" in the real world as they never make sense. Physically it is impossible to have core temperatures lower than TCase. The core temperatures are only there for the processors' internal control logic. (AMD wise, not Intel).

Been running all 8 cores at 100% with AIDA stress test for 8 minutes and still at 52 degrees. That's not bad for the FX-8150 is it? I think I heard the max temp for the 8150 is 61.

Ok, I believe I understand. Thanks for helping me out with this! Now I know what to watch as I run my first Prime95. Just got this processor yesterday and I want to stress test it to make sure I didn't get a subpar one before I can't send it back for a replacement.

Yeah, that's AMD's highest rated temperature on those chips. However, running it at 60, hell 70- probably won't damage the chip. They don't suffer degradation until 97C, however, running them there is not recommended. Personally as a rule of thumb, I go by 65C TCase after much digging in AMD datasheets.

Awesome! Thanks for the info. I will use the 65 as my peak limit for temp as I test and such.

Thanks again very much for your assistance and speedy responses!

try a lot less voltage, its stable below the stock voltage, should save a some c's.
iam at 4ghz on all 8 cores, iam idle at desktop and with h100 with stock fans on max, iam at 34c.its a very hot cpu.

I am running a Cooler Master Hyper 212 Plus.

I ordered 3 of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16835553001

I will be replacing the stock fan on the 212 for 2 of the 3 new ones I bought in a push/pull config and I will replace the my stock case fan with the 3rd. Can't wait to see what kinda temps I will get with that.

What voltage are you running on your 8150 with that 4.0Ghz OC? Also what mobo do you have?
post #29 of 30
I run an 8120 at 4.5Ghz stable and temps don't go beyond 55°c while under full stress (p95 default blend) with a h100 on p/p. This is with all 8 cores fully active. I'm @ work atm but I'll try to get some ss once I get home. I usually prefer HWMonitor for temps, they're usually pretty accurate.

My advice : Watch out for voltage. Overclocking this kind of cpu is pretty easy imo, the only tricky bit is the voltage since I've seen lots of variations. I'm still experimenting with mine, so I'll try to share my oc once I get one I'm comfortable with (I'm aiming @ 4.7Ghz - 4.8Ghz at least)
post #30 of 30
iam using 1.29v in bios and ultra high for the cpu load line. my motherboard is the asus m5a99x mobo, its a 6+2 vrm so its more suitable for a 6 core cpu than an 8. cpu load line on the sabretooth it is medium .

with the cpu load line setting , give it the voltage and set it to high at first, give it a little prime and watch voltage, it should give or take .02 volts adjust till the voltage is the same under a prime load.
