How to stress testing for core-utilization based overclock setting?

post #1 of 4
Thread Starter 
Hi guys,

I've been wanting to ask this question for a while. With the latest UEFI update, my mobo supports setting different multipliers for different loads (core-utilizations).

That is, one multiplier when all cores are used, a different multiplier when only 3-cores are used. etc.

How do you stress test for each load setting?

I am thinking of the following.

4-core load:

test: run prime95 normally. small fft test.

3-core load:

test1: run prime95 with core affinity 0, 1, 2
test2: run prime95 with core affinity 1, 2, 3 (or 0, 1, 3 or 0, 2, 3)

this should test all 4 cores at the set multiplier.

2-core load:

test1: run prime95 with core affinity 0, 1
test2: run prime95 with core affinity 2, 3

this should test all 4 cores at the set multiplier

1-core load:

test1: run prime95 with core affinity 0
test2: run prime95 with core affinity 1
test3: run prime95 with core affinity 2
test4: run prime95 with core affinity 3

this should test all 4 cores at the set multiplier

it's a lot of tests. is there another quick an proven way?

Why would you want to stress test individual cores? All 4 cores/8 threads are going to be running at the same overclocked speed in the end?

Wait, i get what you mean. My bad!

One issue though. I don't think I can stress test all 4 cores at 48x multi without hitting 90C!!! so if the load was for only 1-core, temp would not hit that high.

I see what you mean.

But yeah you need to stress test all 4 cores at the same speed at the same time, otherwise its not going to be remotely stable when you try run all 4 cores at the speed you tested on just one core.

What voltage you at for 4.8ghz? 90C is very high and I would only realistically expect temps that high with the stock intel cooler.
