[DigitalFoundry] Is It Time To Upgrade Your Core i5 2500K? - Page 39  

post #381 of 402

I tested 2800 c16 vs 3000 c16 and found a ~1.74% fps improvement with the latter in very CPU bound sections of Skyrim and Oblivion. I didn't test roaming around outside though.

I can push 1.5v to my 2500k and never go over 75c lol. (have the 212+ also)

This is just one of the reasons sandy was the best generation evur smile.gif

Did not notice this post when I last posted. The insufficiency of my cooler was pointed out to me in the Ivy overclocking thread when I first overclocked it. Which is why I never tested at anything past 1.32v.

My LLC is set to Ultra High. That's what I was advised on the Ivy overclocking thread. Would a different setting help achieve a higher overclock?

Thank you.

From what you said, is it safe to assume that Ultra High LLC helps achieve a higher overclock?

Also, why is Ultra High LLC not advisable for 24/7 use?

Thank you.

LLC increases voltage to offset the drop caused by resistance when the chip is drawing a lot of current. The problems are the same as those caused by just setting the voltage higher in the first place, heat and degradation.

Say you have a cpu core stable at 1.0v regardless of load, if you set your supply voltage to 1.01v it will be stable at idle, but due to the resistance of the traces that voltage will fall below 1v under load and make it unstable. If the voltage falls to 0.95v under load, the ideal LLC setting would bump the supply voltage up to say 1.07v under load, so the voltage at the actual core stays at 1.01v. Now, It's hard to tell exactly what "ultra high LLC" means, but I would personally assume it overshoots, so the final voltage is more than actually needed.

(from an LTT thread)

Because setting LLC to ultra high causes overshoot of your set target Vcore in the BIOS, running the unnecessary risk of frying your chip if you don't know what you're doing.
post #386 of 402
So I was on Newegg look at some very cheap memory (man its sooo cheap now!) and decided to play around with my current sticks to see if I could overclock them a little or something. . .

Well looking at the memory settings in the bios and I wasn't even running the XMP so my timings were 11,11,11,32 and running at 1600mhz. . . .doh!!! Changed the profile to XMP and that brought everything down to 9, 9, 9, 24. Seems to run smoother, no I want to see how far i can take these sticks.

* advise.

Also, only listening to some goofballs in a thread probably isn't the best idea. Tons of people have proven that as long as thermals are in check you can push voltage on sandy regardless the type of cooler.

I'm interested in your definition of bottleneck you wrote there smile.gif, but about the bold part, is the use of both of the CPU words correct or one of them should be GPU?

I was wondering about what benefits would have upgrading an I5 2500K with an I7 3770K. I see it has 8 threads, so it does mean it handles processes better I guess. One acquaintance is offering it to me very cheap because he will upgrade his rig and since I don't really have that much money/need to purchase also a new motherboard + ddr4 ram yet(until the next 4 years I guess) I was thinking if it might be fine to accept the deal or not.
