Is it true that thermal paste takes around 2 weeks to set and perform at its best? Anyone think it would make any difference for IB?

 

[Ollie1132]

Thermal compounds take a certain amount of hours to bed completely. And probably not it only ever makes 1-3C difference anyway.

 

[Buckster]

Your using the H100 right Buck?

Noctua NH-U12P SE2

 

[Ollie1132]

Oh yeah you said earlier xD is the IC Carat TIM worth grabbing? OCuk only has the 4g one instock... and I need some TIM for the Heatsink reseat. I just hope my CPU never burns up... Id never smell it due to the smoke that I smell thanks to being above the door in my section of flats >.<

I thought max temps are 77c, you guys that are hitting 90c+, surely you don't want to run at that temp just for an OC.

@ ollie1132, I would suggest you back it off on the OC and voltage until you are sure your heat sink is mounted correct.

 

[Ollie1132]

Its fine for now. The max temp is 105C and Im only just hitting 90C at 4.5Ghz usually have about 75C on my 4.3Ghz I just wanted to see if I could get 4.5Ghz stable. Plus the stress test temps will never really be hit realistically.

I don't think so, the max temp will not be 105c

 

[Ollie1132]

Well it's definately over 90C. Max temp for sandy was 100C was it not?

 

[crinkleshoes]

It is Intel's quoted max, yes. This is when throttling begins.

Recommended self-constrained max for IB = 90C

 

[Ollie1132]

Im sitting just on the 90 mark now. (Ill jump back to my 4.3Ghz in a couple of hours just checking the 4.5Ghz is stable so I can save the profile ^.^) So the IC Carat TIM should I grab some? or get the Artic Cooling MX4?

 

[hyperst]

Well it's definately over 90C. Max temp for sandy was 100C was it not?

From what I have heard it is recommended to keep sb below 72c, and ivy below 77c

I use the ic diamond, but to be fair i got it free, if i was buying i would go mx4

 

[Ollie1132]

Doesn't worry me too much I have intels insurance xD realistically outside of stress test I wouldn't be sitting over 60C if Im honest.

i can hit 4.7 with 1.29volts using the H100 cooler ran prime for 2hrs and hit 74C Max (1.28V @ 4.6GHZ feels the sweet spot for me)

but run as standard @ 4.2 even with prime running i hit a max of 64C happy with that, ive seen 4.9 system boots but then i get BSO

my 1st time OC so dont really have 2 much of a clue how 2 get the best out of the CPU

 

[Ollie1132]

I wonder if I can boot up at 4.6Ghz on 1.25V...

 

[gadget^]

1.28V @ 4.6GHz works quite well for me with low ish temps 65 - 69 it feels the sweet spot.

 

[Ollie1132]

Nice my temps won't be anywhere near that currently I won't even check 4.6Ghz for stability since my 4.5Ghz gives off a lot of heat atm.

 

[skyjawa]

what a difference a bios update makes, updated my V Gene (was on a pre-release bios ... wasn't even production bios lol - that old) - and running the 3770k on lower volts

4.5 seems ok in Prime with mem at 2200 - quite pleased so far - its probably as hot as expected - but very very fast - and very low power usage

Can you just to clarify what you have the green set at? 10-10-10-28-2T? With 1.5v? I'm on 1866 9-9-9-9-28-2T at the moment on I think 1.45 or might be 1.4v.

 

[skyjawa]

When i say broken i mean they are all the same, levels 2 through 5 dont provide varying degress of vdroop they behave the same.

Now i would be happy to be proved wrong and ASrock have actually bothered to fix this LLC issue, but they probably haven't.

.

Well for me with my volts set to 1.25v and llc set to auto which was level 5 in the BIOS Windows would crash shortly after login. Overriding this on my Extreme6 to Level 4 and its working a treat, so there must be a difference!

 

[skyjawa]

4500 seems to be the overclock for my 3770k for now

we're not talking cool - but this is after quite a few runs of small AVX prime

Wow thats a lot of heat! I'm running my 3770 at 4500 with 1.25 volts (drops to 1.176 ish on load) and I don't get temps go over 75!

 

[skyjawa]

My 3770k is currently at 1.25V just checking how stable it is at 4.5Ghz with this voltage (Im hoping I can lower the volts a bit since some people get 4.5Ghz at about 1.8v but I needed at least 1.2v to get to windows) my temps are sitting at 90 for cores 2 3 and 4 for max and just under 80 for core 1. (taking it core 1 is the more realistic temp with my heatsink being seated badly) hoping this is stable and isn't the kind of temps I can expect after a reseat.

I was the same Ollie, 1.2 would get me to windows, with a sluggish login appearing then would BSOD. Since we're running the same mobo and nears as dammit coolers I'm sure we'll find we're very similar in what we can achieve!
