Stress Testing Mode and CPU Heat

[CalVic]

Heya all,

I'm currently in the process of tweaking my 8350. Currently stable at 4.8Ghz at around 1.488v. Running Prime95 @ Small FFTs my temp rises to about 56ish to around 57 depending on ambient, I suspect I will never run an application that would stress the CPU to that temperature.

But I want to overclock more (Gotta get the best Price to Performance ratio eh?), and I'm already nearly at the limit due to the Max recommended core temp of 61c

So, I've been running OCCT using the Large Instruction Set, It say's that this is the best mode for error checking. But the temps are around 51 to 53 as it doesn't generate the extra heat Small instructions do.

Would it be fair to say that this is probably the realistic full load temp would be? and should I base my overclock temp limitations on this test rather than Small FFTs in Prime95 and Small Instruction Set in OCCT

Just curious as to what other folk are doing. I've seen some people reach 4.8 to 5Ghz on the 8350 using more vCore than I but saying their temp is around 51c and below using an H100 Cooler.

so your temperature is core temperature or socket? on my OCCT 4.4.0 the temp
is not right compared to HWMonitor and speedfan. I read the ROG guide on OC
and they'd had the CPU to 76° and mobo socket to 30° this is quoted:

With the overclock applied, boot back into Windows and repeat the earlier stress test, running AI Suite II to monitor temperatures and CPU-Z to check frequencies. In CPU-Z the CPU should now report as running at 4.8GHz (or marginally higher depending on baseclock fluctuations). However, you’ll also notice the CPU temperature has increased a lot too; our setup here recorded a delta T of 49°C. This is hot, as expected, but still within the TJMax of the chip though.

so depending on softie temps can range widely. I chose the HWMonitor for
verification on temps which are 8-15° lower than OCCT which is 63° on my
crosshair v formula-z. just for reference.

Have you tried the 2nd tab in occt using all logical cores and avx ?

I find this generates the most heat for me, along with intel burn test..

not at the same time...

 

[FTLN]

No not at the same time

Yeah, I don't follow the CPU Temp as that's the socket. But I do keep the eye on Core Temp, and that's the one that hits around 55 ish
