Overclocking General Questions

[AMD Lover]

So I'm starting my overclocking with 4.6Ghz @ 1.35v (Ring Bus 4.5Ghz @ 1.3v) and VCCIN (Input Volts) @ 1.9v.

 

I have about a 9°C range in core temps from the first to fourth core. My temps are getting a little toasty too. I know they will at this voltage but should I be getting lower temps with my Enermax Liqtech 240mm? (RealTemp Snapshot Below)

Wait isint the max recommended for the Hashwell series 80 degrees?

Welcome to HAswell non-refresh is all I can say. Its TIM is terrible so the temps are poor as well

That's a personal thing really, I prefer sub 80 but it can handle up to 95 without serious degradation. I Personally don't recommend exceeding 85C MAX

I've reset the ring bus to stock and have changed some other settings. I'm gonna try 4.5Ghz Core

 

 

OC failed BTW

We need your input


pesonaly if the temps hit over 95C when stressing its a fail.

I went to 4.5Ghz and I'm still at 1.35v which is probably to much and I will move it down to probably somewhere around 1.33v but I'm already staying at and below 95°C

I may have missed it in your OP but what program are you using to stress test?

 

While those temps are on the higher range you won't reach those in a 'normal' day to day scenario so you could run it.

 

Personally as long as all of my cores are averaging around 85c and only jumping to 90c in the test briefly that's fine.

do not use prime95 if thats what you are doing. the newest versions are very bad for the cpu and can do permanent damage to you cpu. i use intel burn in test or something like that.
Those temps are a little high but thats what you can expect from that cpu (had it too)

Intel ETU @ 4.5Ghz with 1.35v (Will prob be able to lower) I'm sticking around 83-87C with jumps to 93-96C

That should be fine then. I'd work on getting the voltage as close to 1.3V as possible now

I was planning on trying it at this voltage for about 30 min intervals and dropping it .005 each time. Would you drop it in bigger intervals like .010?

I'd go straight for 1.3v (unless you know it isn't stable at that) myself. If you know 1.3V wont work try 1.325 and work from there in 10mV intervals.

 

As I bench a lot of chips I like to find out quickly what works- so I just do 4.7/1.3 as my first clock to gauge the chip, it's more efficient than literally raising 100MHz and 5mV every time as you could be there a while.

I did 4.7Ghz @ 1.41v and it failed. I'll try 1.325v I'm almost positive it would fail at 1.3v

Alright, best of luck

Could have been my ring bus OC that failed the other two settings. Do you overclock your ring bus at all or no?

I tend to leave it until I know my core clock is stable. Reducing variables is a good way of getting the most accurate stability testing results.

Does an IGPU crash mean that I need to raise my core voltage a bit?
