CPU CPU upgrade performing worse in game benchmark

R20 uses AVX which may hamper your clock speeds.

Use R15.

Asus Realbench is decent also.

 

I think I got it. Cinebench R20 on there @ 4.5GHz is 1676 marks, I got 1668 score, and also I found another 2600K 4.5GHz result on Google that was 1688.

I'm noting the 3DMark Time Spy results on the site now and will try it at those speeds.

Origins is bizarre. I'd rather have the 8 threads as that seems to stop the NPCs turning into faceless undetailed ghouls (though locking at 45 FPS on the 2500K helps).

The 2500K was at 100% loads all the time on Origins and other games (hence why I was looking out for an 8t upgrade), so wasn't expecting a worse performance.

 

I have the 2500k back in... and this is utterly bizarre... tried the Origins benchmark three times...

2500K before installing 2600k - Frames score: 6634, FPS: 57, CPU: 16ms, GPU: 17ms

Just now after reinstalling 2500K - Frames score: 4984 / 5253, FPS: 43 / 44, CPU: 23ms / 22ms, GPU: 20ms / 19ms

WTF? This couldn't be the new Windows 10 update could it? It's either that or the mobo's gone funny...

 

Specture and meltdown patch is now applied to both CPU's...

 

Reset bios to optimised defaults?

 

Luckily I bought a CPU + mobo combo... JFC I'm going to have to change the entire motherboard aren't I? All this for easily popping out a CPU and putting a new one in.

Wait this spectre meltdown thing is something that happened yesterday?

EDIT: I downloaded inSpectre, it said my system was protected and my performance was 'slower'. I disabled Meltdown and Spectre, restarted PC, and it made no difference. Benchmark was identical to before disabling. Spectre / Meltdown is not it.

Yes, although the only thing that's ever been changed is the fan control, CPU multiplier and CPU voltage anyway.

 

What memory speed is CPUID reporting?

 

Same as normal. It shows 533 MHz for 24GB.

 

1066? Wow that's slow memory.

 

Thanks.

 

Yup, it was the board!

So lucky I bought a CPU / mobo combo rather than just the CPU. At a slightly lower speed, bent pin, wrecked GPU socket, reused thermal paste, less RAM and all, the 2600K is now performing as expected in Origins!

The CPU-Z, Cinebench R20 multi-thread and R15 benches are pretty much the same as the other mobo (guessing <100MHz and a little extra RAM won't make a big difference). So... whatever... not gonna try the 2500k nor my original board again... to find out...
