my default XMP@2133 kit is the same timings you are running now 9.11.10.28.2T default from the mushkin kit... it was closest I could find to a more ideal default kit of 9.11.10.27.1T but I don't think I could find a quad kit dialed in at that... mine goes the 27.1T easily and there is a difference in Aida and most Linpack runs lowering just those two final timings.

Hmm... i went with the G.Skill Ares 16G kit so my XMP is actually 2133Mhz 9-12-10-30-2 (something round there...) but the ram was stated to run at 9-11-10-28-2 so i just went with that lol... i'm new to OC and can barely do a decent CPU OC so i think RAM is just a little too much for me to handle right now... at least i know i might be able to improve me GFlops abit with a bit of RAm tweak

Cheers

I've recently OCed my I7 3820 to a stable 4.5 Mhz and was just wondering if i could push it any farther. I am using A Noctua NHD-14 on it. The case is gigantic, has 7 fans and kept clean. Air flow is nice. Under a full load the cpu runs at about 63C to be exact. I achieved that by increasing the BCLK to 125.0 and did not touch the multiplier at all. Using the EVGA X79 Classified board.

Mostly want some insight whether it would be safe or not. I know enough that my RAM will be fine during the OC, and how to handle it if it doesn't, mostly just CPU being able to handle it with my setup. Weighing the risks and rewards thumb.gif

Thanks!

what's your vcore and VID ?

I am idling pretty low c on a 4.5ghz using an H100i 28 to 29c and pulling it up to 42 and 43c according to realtemp and various monitoring apps... that's after a few 6gb memory runs on LinX and IBT.

my bus is at 100 and my strap is unchanged so that may have something to do with it?

What would be the max safe temperature and voltage for a 4820K?

We don't know yet, but if the 3820 is an indicator it would be about 1.5 and around 90c.

hell man I'm a new too, I'm watching these guys like a hawk around here... deciphering their code. I've got a somewhat narrow cure and a little past experience in terminology but not O/Cing.

early on I hit the junction a few times on this 4820 right at about 100c... in my guesstimation depending on your cooling you probably wouldn't want to take it past 90c and that is more than likely hi for running a strong bench.

most folks seem to be running 80c and below strong benching and those folks have custom loops, or better equipment than an AIO watercooler at any rate.

Yeah i'm just going around picking the brains of others atm... but i still think i should leave RAM OC for later...

Ram oc and 2d benching are fun things to do...takes its toll, and is harder to learn than regular cpu or gpu oc.

Download maxxmem to compare your results, and also fire superpi 32m to test your efficiency.

So I have 4.8ghz 1.37v and a max temp of 76c on my 4820k. Does that seem good to you guys?
