i7 3820 - 4820 Overclock Club - Page 64

post #631 of 6491
Well, I got 4.75GHz (mem at 2000 - 10-10-10-30-1t @ 1.425V) seemingly stable at 1.38V. Temps on core 0 peaked at 74 but the other 3 didn't break 70C.

I say I have it "seemingly" stable, as I do have one outstanding issue. Resuming from sleep does not seem to work. Just hangs. From cold boot, works fine, under load it works fine, but resume from sleep hangs it.

Got so many tweaks active it would be hard to list them all.

Got a number of things I could try tonight such as lowering memory speed, disabling thermal monitor, etc, and trying to find cause. Just thought I would mention it in case someone had similar issue and had a good suggestion.

Hope I find the cause and find my max memory OC by Friday, as I would love to actually play some games properly this weekend smile.gif

It's unbelievable how smooth BF3 is at 4.75 though, compared to the 2500K at 4.5 Not that the 2500K was bad, but the 3820 seems to handle those occasional heavy load spikes a bit better.

Have you noticed any other improvements over the 2500K? Temps/power consumption etc? Has the upgrade been worthwhile?

I'm still unsure which chip to go for, 2500K or 3820 and although I appreciate that that question has been done to death, it is handy hearing from people who have actually owned both chips. Benchmark tests are just that, benchmark, and I'd prefer to get a picture of the cpu performance over time with an actual user.

My brother has the 2500K and I have the 3820 and the performance between our two rigs seem fairly comparable (apart from he only has 8GB of RAM).

Well, I have been spending so much time installing and tweaking that I have hardly had any time to do much of anything besides a bit of BF3. BF3 does definitely run a bit better, and that is with my GPU's at lower OC than I had them with the 2500K.

To be honest, I wouldn't say there is a whole lot of difference between the two, but I do prefer my X79 Formula and 3820 to the 2500K and P8Z68 Pro Gen 3 I had.

I absolutely love this board. The CPU is a place-holder (pretty decent one at that) until Ivy-E.

Ah, thanks for that. That's the kind of feedback I was hoping for. I was going to go for 8gb RAM myself with whichever chip I finally decide on. lol it's taking me weeks to make up my mind.

I finally put together my rig and of course did some overclocking!

382

I'm not sure if these are good temps or not, can someone give me an opinion here? I'm on a loop with just the CPU only. Although I'm kind of skeptical on the memory, I have it on the bios as XMP @ 1600, 9-9-9-24. But I'm seeing stuff that I'm not familiar with, is this normal?

I may try going for a lower voltage, but probably will do some Prime95 overnight and see what happens with my current voltage of 1.34v.

for my part Vcore arent a worry i just dont bother with that i give has much Vcore i want to get the mhz i want smile.gif simple at 1.39v i get 4.7ghz i want 4.9, 5.0ghz i will give it 1.52v simple smile.gif since i have switch too intel ,i5 750 , i7 2600k and now i7 3820 i always did 1.5v and all those cpu are still working now . but a great cooler is a most now i Watercool so 1.52v is no worry with temps i tried 1.58v to get 5.2ghz but didnt work i will try to get there soon if possible.anyways good luck sir and if you air cool i would not recommend 1.5v just to say.

Wish I was brave enough to run those volts through my CPU, even if I don't plan on keeping it forever.

After a bit of playing, yesterday I figured out that the CPU didn't like jumping straight to 4.75 from sleep mode. If I set the CPU ratio to something like 30 (giving 3.75GHz) and used the turbo to go to 38, then it would resume.

And after all that, have decided to simply use bclk and turbo to OC to 4.575 so that I can get C1E working to reduce idle power usage. With that I have my memory at 2270 at 11-11-11-30-1t with 1.475V.

I will have more of a play around when new BIOS get released, but for now, think I need to play some games and relax. I find OCing quite stressful sometimes frown.gif
