When I had it some things i found that helped:

1. Mess with the PLL, at really high clocks, I found that it played a significant role. When I hit 5.4, I think i was using 1.75v

2. Don't be afraid of vcore. these chips are like tank, up to 1.6 won't kill it. I wouldn't run 24/7 that high, but for benching it is fine.

3. BLK is cool too. If you can get even something small like 102MHz, it will help.
100x48=4.8GHz
102x48=~4.9GHz
102x49=~5.0

If all else fails, buy a few more chips and hope to get lucky.

I haven't really heard of ASUS boards other than the MIVE being that great for high clocks, but 5.0 shouldn't be too hard.

Maybe if you can cool it down it will go 5? Change/add the fan on the cooler? Change case fans/direction? Open the case and blow A/C from a window unit?

I see no problem. Just remember the CPU will throttle down at 95c and 98c is the max max temp.
Some people are way too conservative about the SB temp...
I personally don't mind going to 80c+. been doing stress testing almost everyday for a month or so. I see no degradation whatsoever. Keeping it very stable. (seems like hi voltage will do degrade the chip in time whether you have your temp low or not.)
Reaching 84 in IBT/LinX (AVX) means real life max CPU temp would be about 75c~80c, idles at 35~40. (including Prime95)
That seems all fine to me.
I personally want my system to be as MANLY as possible.
I make it work hard and won't let it stop.
When it dies then it dies. So be it.

Dude are you serious? 84c IS absurd, thats only 10c away from the CPU throttling itself due to heat. And 15c higher than what 90% of us would recommend.

Also @ Reflex... 1.6v on a 32nm chip? Really? REALLY?

Yeah sure you won't kill it, but christ its gonna degrade like no ones business.

he's benchmarking it. that's as high as it's going, so i see no problem other than the chips' life will be shortened a bit.

Personaly when i see a chip hitting high 60's i start messing with it to drop the temps, but that's just cuz i don't like rebuying something i aleady had but was a jackass and broke it.

His right 84c is not the best but manageable, other than sress testing nothing will get the cpu that hot. I benched at 1.7v a few times and still was able to pass 20 runs of IBT yesterday. Im not saying all of them are, but damn these CHIPs are quite resilliant, however like you said there is a high chance of degreadation when using such high voltages.

Yeah like I said, for the short term stress test, I'm certain the chip can handle ~85 or less, since then it'll normally run a lot less.

I heard the BLK doesn't budge, but I'd love to try that. If it works, it may be the tipping point!
However, no way am I going above 1.52. Just too risky IMO. I'm crazy, but not *that* crazy. +Rep.
post #18 of 24
I have the same problem. Need too much voltage for 4.8. I've booted to 5ghz but I know it will require @ or over the max voltage of 1.52v

I tried upping my Bclk also. Saw instabilty. Wasn't able to boot to 5ghz with just 101.

i've benched one of my chips at 1.8v on water.

it didn't die, (nor was it stable bsoded after the physics test in 3dmark11)

these chips are much more resilient than most people think... to op (keep your temps bellow 90C.. play with cpu pll, mine needs stock or higher for anything at or above 5ghz, but some will like it to be lower)

Also do not increase blck as this will distribute some of your juice to the imc and will make it harder for you to clock that high stably. DECREASE blck to 99.8 or lower and 5ghz should be easier.

-Turn off any of the functions you aren't using in bios. ex. usb3, built in audio, lan, etc.
-if you do increase blck, you'll need to increase system agent voltage also. (not recommended though, i did it and got 106.5x47 for 5ghz and high clocked ram)

Yes I'm soooo serious. It is all fine.
Give me an example of one SB died on 84c please.
Then I'll agree on you.
Until then, it is fine. Even if it gets to 95c and throttles down, the CPU won't DIE. If it dies on 95c, then the throttle should be set lower, isn't it?
Throttling is for protecting the CPU.
Of course the limit varies between the each CPU but in general, it has to be fine or there should not be throttling and max temp set at 95, 98c.
Intel put out a Tcase max temp of 72.6c.
And the max CPU(core) temp is usually 15c above tCase value which is around 86-87c to be safe.
And that is the safe 100% load 24/7 value.
In stress testing, max spike will only be a short period of time.
It won't keep the 84c throughout the test.
Even if it dies doing it then it's intel's fault. It is still under the intel warranty. (as long as you keep the max voltage lower than the intel put out 1.52? I forgot...) So you can get it back for free anyway.
The conclusion = 84c is fine. Sure it's better to be lower but it isn't ridiculous whatsoever according to me and Intel. And I guess I'm in the 10%. But I'm proud to be in that 10%.
