4770k and prime problem

[LIGISTX]

I know I know, Don't run prime with a haswell because it will draw to many volts and blow everything up. 

 

Don't worry, I know. But, I have AIDA64 6 hours stable @ 1.2 volts with a 4.4 GHz OC on my 4770k. That is with the full test, RAM, CPU, FPU. Even got it stable at adaptive volts which was nice!

 

Went to try prime95 blend at manual 1.2vcore, bsod real fast. I am up to 1.230 vcore already and so far have not found more than 5 minutes worth of stability. I am not the type of person to let an overclock be "stable" if it can't pass a pretty big battery of tests. My temps are fine under CM Glacer 240l, average temp is mid 60's, so pushing a few more volts doesn't scare me. I just want to know how many extra volts people tend to push to get it stable? I feel like this is pretty crazy..

 

I guess I could try cinebench instead. but eventually I will want it to pass prime 95... so I figure better start now.

 

*BTW, Asus Gryphon, 2133 RAM, 1:1 Ring Ratio*

Are you monitoring your volts and making sure they are at what they should be during prime95 test?

[TheNinjaNextDor]

It seems like you got a pretty good chip. You could try going to 1.25V and probably get it stable.

Yea, CPUz has it @ 1.232, .002 above BIOS setting.

BTW, I am on a Asus gryphon just btw. And I am running 2133 RAM, with a 1:1 ring ratio

Does prime usually need an extra .05 votls to get stability? 

 

I am actually right now staying stable for a bit, at least longest thus far @ 10 minutes of blend @ 1.23

 

And this is a decent chip? I thought good ships could do 4.6 @ 1.2 in AIDA64. 

 

*edit, spoke to soon, bsod @ 12 minutes. lol

[TheNinjaNextDor]

Then yeah try a little higher.

My CPU is at 1.45V lol

I think that Prime got an update for Haswell, you might want to check on that.

I think I am using the latest version, I will double check. And man, 1.45, you have more balls than I do. Plus, on haswell I wouldn't be able to keep temps down with that many volts! even with 2 SP120's at full revs, its getting pretty hot every .01 I jump.

I get to a about 80C during Prime95 tests so it's not that bad. For a few minutes I was at 1.5V and 4.8GHz.

Yeah Haswell would just burst into flames.

Yea, right now I am at 1.241 in cpuz and hitting low 70's in coretemp with the 240l... Unless you delid and custom loop it, it would literally catch on fire. lol

 

Deliding is starting to sound real nice right about now. But, I am happy with 4.4 ghz, just gata get it rock hard stable, hopefully with sub 1.25v

You got a pretty good chip actually. I was thinking about delidding, but I really don't want to risk it. I might do it before I upgrade to whatever the Z97 i7 chip is. I need to do that before I get a new GPU.

Delidding and upgrading to a custom loop is seriously such a fun upgrade to do. I helped 2-3 guys in the wee days of LTT do it and it was a blast helping them through it and one of them made a awesome log of him doing it. Pretty sure one of them ended up running his 3570k @ 5Ghz and in the low 70c range.

 Holy crap, High 80's @ 1.241v. lol. Prime95 is insane. I am not even 100% sure I am not throttling at this point, although CPUz has me @ 4.4 ghz still.

 

And delid might not be a horrible idea, as long as I don't kill the chip doing it. I would keep my glacer 240l, because I do like the ease of it (still in college so I move my rig from school to home few times a year). But I could probably knock off what like 15c with a delid?

Something like that. Prime always makes my chip go way hotter than any other stress test, that's why I usually don't use it.

The temp decrease can be anything from 2-5c and up into 15-20c all depending on how badly the IHS on the cpu is mounted and how bad the thermal compound is. If you are getting high 80's at 1.241v then I would guess a minimum of 10c decrease. I haven't really read up on the numbers for haswell delidding as much as Ivy. Also if you are going to delidd getting the coollaboratory liquid metal thermal compound is a necessary or atleast any liquid metal thermal compound.

I wouldn't use it either because of these temps, but I really like knowing the OC is stable, and if that means one night of actual torture test, I guess that is what it takes? It sketching me out tho, these temps are pretty high!

If you want to test overnight try Intel Burn Test.

You think it will result in less heat? I don't think one night of this will kill my CPU, but, I don't think its having a very fun time. lol. Right now it is STILL stable @ 1.241, and at this moment is only in the high 60's. I guess temps are VERY dependent on the test prime is running. It is 45 minutes prime stable. I might just call it a day considering AIDA64 took .043 less volts for stability... and that is much more demanding than any average thing I will be doing on the PC. I just really like the idea of KNOWING you are stable.

 

WOW, like clockwork every frikin time. I start to write a post saying heck yea I am stable, BSOD. LOL. Its like magic!

LOL

I think it would be more of a sure bet that it wouldn't degrade the CPU as much as these other things.

I tested mine for less than 20mins and called it a day lol. The only time a test for a while is when I run Unigine and OC my GPU.

[LIGISTX]

lol yea, I just did a bunch of reading. looks like prime might just be stupid. I figured something that tests the crap out of the CPU means it will guarantee stability, but I guess that isn't exactly the case. Intel and Asus both say use aida64, so I guess I will just stick with that. I might keep the votls a bit high the just to air on the side of caution, not like it gets too hot anyways.
