This is my first attempt at an overclock. I followed one of the tutorials on youtube on how to overclock my x6 1055t.

Specs:

AMD Thuban X6 1055t 2.8ghz
GIGABYTE GA-870A-UD3 AM3 AMD
G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Dual Channel


this is what i overclocked to in bios
Turno core: off
CPU Clock ratio: 14x (3500 mhz)
Northbridge: 8x (2000 mhz
FSB: 250
Memory - 5.33x (1332 mhz)
Cool and quiet: on

Here is a screenshot of prime5 running with monitoring tools



Is this overclock safe?

Are my temperatures ok? i dont know the difference between core, temp1, temp2? (also in CPUID hardware monitor TMPIN2 is 80. is that safe)?

Which temperature should i be monitoring and what is the maximum it can reach?

any help will be appreciated. thank you

The CPU temp being 80C is far to high but I would expect it to be only 10C higher than the core temps so I suspect its a faulty sensor, assuming it is the temps are fine. Ther motherboard temp is fairly high but not problem high.

Looking at HWMonitor, The TMPIN2 80c reading never changes does it ? That I believe is a bum NB reading, Asus boards will report it as a constant 128c like mine. I believe TMPIN0 is your MB temp, it should be a couple degrees over your ambient and only fluctuates a couple of degrees. TMPIN1 should be your cpu temp, idling at 34c and rising to 51c while stressing. Your core temps vary about the same as my proc., about 10c under cpu socket temp at idle and 5c under socket temp at load.

yup under 6 hours of stress testing under prime95, TMPIN2 stayed at 80 the whole time so im assuming its a bum sensor.

Im using the stock cooler with my processor. Should i go for an aftermarket cooler or are my temps good enough to use this as a stable system?

sorry, coretemp matches the "core" reading in speedfan and also the "core #" in hardware monitor. basically during the whole test it was at 25 idle and like 45 on full load

Your temps are fine at 50C. TMPIN1 is your CPU temp. That is the temp that you can take up to 62C so you have a bit of headroom before you reach your limit. Try upping the voltage to 1.475 which is the turbo core voltage and put your overclock to around 3.75-3.8 ghz. You may be able to keep your temps under 62C and remain stable.

I'm amazed you can run 3.5Ghz at 1.3v. I need at least 1.375 to get away with that on my 1055T.

Yep, TMPIN1 is the motherboard's calculation of the CPU temperature. The core temps appear low - I always go with the highest temp.

Almost all (if not all) of my Gigabyte boards have that erroneous 80C temp for TMPIN2. Ignore it.
