On which temp silicon degradation starts?

socket temps are normally 5-10C over core temps

i dont care about socket temps really and ive never had an issue

After I put cooling on the back of my socket, idle temps were the same core/socket. Although at load the core is usually cooler. I think it is still important to monitor both.

I like to stay within 62C on core, and 70C on socket. Thats just me.

Edit: For instance, if your core was 61C (still within spec), but your socket was 75C, that could still be dangerous.

You misunderstood me completely.

I said that both temp should be watched.

And you disregard tcase completely to go with temp. which is better suit you.

Tcase must not go over 61 according to Amd.
Tctl must not go over 71 for all Fx chips.

And with 80 degrees on tcase you are well above safe temp.
Maybe AMD points that 61 degrees just for fun.

Everyone uses it's own, comfortable, limits I guess.

My absolute max is either core or socket 72c.

Mine are actually very close to each other: Warning: Spoiler! (Click to show)

Dude, stop it.

Your keep talking about tCase, we are talking about something else.
We put our focus on core and socket....

Why are you so persistent?
Why are you defending one guy who looks to know better then all of us AND amd.

Really

Really

AMD talking about tcase:

Dear Customer,

Your service request : SR #{ticketno:[8200609443]} has been reviewed and updated.

Response and Service Request History:

I understand that you have questions regarding specification. If this is incorrect, please let me know as the information provided may change.

The 61℃ is the max Tcase, it is the maximum case temperature specification.

The 70℃ is max Tctl, it is a non-physical temperature on an arbitrary scale that should be used for system thermal management policies.

If you have any other questions or concerns, please do not hesitate to reply to this e-mail directly and I will try to provide any additional information that you may require. Thank you for contacting AMD!

In order to update this service request, please respond, leaving the service request reference intact.

Best regards,

AMD Global Customer Care

It depends on your setup is my point. As I said my scaling changed alot after I started cooling my socket. Other factors may include motherboard used, or airflow in the case. So you can not always coun't on core being x-amount cooler than the socket. smile.gif

Also scaling will change depending voltage being used. So like I said, it is not a bad idea to monitor both. wink.gif

Well, as far as anything past 1.4v I will freeze almost instantly regardless of clockspeed (like 1-2 seconds in to a test). I would worry about getting stable if I could get past that issue first.

Running 4.8 on 4 cores was just a test to see if it was clock related. What was interesting is that I did not insta-freez while on the 1st 4 cores, but as soon as I changed to 1 core per module I was back to insta-freezing. It was speculated that maybe one of the latter cores may have higher leakage, but If that is the case then voltage should solve the issue. And apparently it doesn't.
So it is my belief that the 3rd module is weak. Only way to tell I guess is to put the chip on to a loop. rolleyes.gif

It was also speculated that temp may be the only issue, however I do not believe the chip is hitting 70C in less than 2 seconds (faster than software can report the temp). I fail to see why cores 5-8 would overheat in 1-2 seconds, when cores 1-4 do not. It was speculated that if one of the cores from 5-8 were leaky, then maybe that would explain why those cores temps would skyrocket in comparison to the first 4 cores. But I'm not so sure I can go with that. I never even see 60C before it insta-freezes.


Here is my last test at 4.5 Funny thing is IBT failed. Then I upped the CPU/NB voltage and got better results with IBT, but can't remember how many passes. IBT is new to me, and I sometimes question its reliability. (Sometimes you pass 20 passes, sometimes you don't) Same could be said for any software I guess, if your not actually stable hehe.

Multi only, RAM settings auto.

CPU/NB 2200 1.2v

HTT 2600 1.210v (I believe)



It's different. I like it.
I am now thinking about some bios settings, have they been discussed yet?

I know my system freezes when I get too high. But that is really TOO high. Like benching on 5.3ghz with 1.6v.

I find it weird that you actually run 4.5 with less then 1.4v, but can't get 4.6 with 1.45v. Hmmm.
Do set your ram manual though. Everything that says auto, I don't like. tongue.gif

How are the other settings in the bios?

How are the other settings in the bios?

My board does not have a lot of the extra settings that the kitty has. I have tried a lot of different settings for vcore, cpu/nb voltage/speed, htt speed/voltage, and the two choices I have for pll. Nothing seems to make a difference.

I left my ram settings on auto because I am not overclocking the RAM yet, and the only settings I know anything about (the standard timings, and voltage), are being set correctly with auto (with the exception of DRAM voltage). One funny thing though, I noticed since I got this chip and updated my bios, the board is setting DRAM voltage to 1.58v instead of the stock 1.5v. So I set DRAM voltage to 1.5 manually. Strange huh?

All power saving features off.

I ran 4.6 at 1.384v and prime seemed ok (couldn't run for hours because of temps), but again IBT failed. Temps were high, so I started fooling with 4.5 instead.

Here is 4.6

Edit: had one wrong picture.

Like I said, on all 8 cores, I can not go past 1.4v at any clockspeed (even 4.5) or I will instafreeze. (Or on one core from each module for that matter)

I can go 4.8 past 1.4v but only on the first 4 cores, not on 1 core from each module. (No testing done except to see if it would cause insta-freeze.)
