post #4601 of 19539
anyone crash from x264? i crashed but i dont know why or where to find the files
post #4602 of 19539
For me x264 freezes if the cache is too high vs. cache volts too low for it. It doesn't cause a BSOD. IMO you can eliminate cache as the culprit.

However, last night I did get a BSOD 124 (still haven't seen one 101 code) and 1 freeze. I raised my cache from 1.23v to 1.24v and VCCIN from 1.64v to 1.67v and that fixed it. If I just let x264 do it's thing alone, it'll run fine but if I surf the web etc, it caused that issue.

Also noticed that after I raised those volts, my FPS went up as much as I gained when I went up from x43 to x44 multi. So obviously I was just at the stability level and it was affecting performance too that I couldn't tell just looking at software.

my computer just restarted suddenly without bluescreen but i look at problem details and it says 124. So i was a bluescreen i guess. i will raise voltage.

I've been working on overclocking my 4770K, but seems like thermal issues are going to hold me back for the time being. I'm running a 42x multi at 1.210 vcore, 1.800 vccin, 38x uncore. EIST and C states are disabled until I get everything 100% stable. As of right now I'm running 85-90C with a Corsair H100, which seems a bit high to me for the freq and volts I'm running, maybe I used too much TIM, so I might try reseating and applying less, but I want to give the AS5 a chance to burn in first.

I'm sure delidding and using CLP as a TIM between the die and IHS would help immensely, but I just don't have the cahones to take a hammer to my 4770K, especially since I don't have the funds to replace it if things go wrong. I'm also concerned about the reports I've read of cracked dies down the road after delidding.

I don't mind building a custom loop (I plan to at some point), but I don't think it will help since I saw almost no reduction in temps going from my Hyper 212 to my H100...

Don't bother giving it a chance to set. It takes 200 hours and is only a 2-3C improvement. Clean it of with Isopropyl alcohol and reseat using the pea method. Oh, and don't use a pea size pea dot. Just a dot, really. The pressure of the cooler will spread the TIM for you.

Yeah, that's what I always do. It was much less than a pea (that's way too much), probably about 1/2-2/3 the size. I'll clean and reseat tomorrow, and adjust the amount based on how the spread looks.

If the spread is bad, don't just overtighten. Both your processor and block could have concave or convex surfaces, which means it is time to lap! If I was a betting man, I'd bet you applied too much TIM. AS5 is pretty good TIM, but it spreads too easy IMO.

That's my bet as well, I just don't have the motivation to tear it apart again today to check. I don't think I'm ready to lap it yet, since that is a one way street to warranty denial in the event I ever need to send the CPU back. Are the IHS on the Haswells typically concave like the previous generations of Intels were?

That I do not know. Lapping is usually just for that last 2-3C, although some people have reported higher, although I believe they were also de-lidded. I want to lap and delid so bad, but I don't want to void my warranty and after the money I have spent, my wife would murder me to think that I spend 340 bucks and then broke it.

I can get a new 4770K from Microcenter for $270, but that's still a chunk of change when I have other parts of my rig that need replaced without throwing money down the drain. I would probably delid before I lap, I just can't get over the fear of taking a vice, block of wood, and hammer to my CPU.
