My SB-E 3820 Build (C2 Stepping)

[Arachnotronic]

Then I look forward to IB-E with improved latency on the quad channel controller. 🙂

I have a feeling I may jump back to the mainstream platform only when Haswell hits the streets only because I am impatient and cant wait for the Haswell-E. I really wish they would release Haswell high end first.

They won't release HSW-E first -- the "E" chips are based on the server/workstation chips, and those require significantly more validation than the client products. This generational lag is here to stay. On the bright side, though, for threaded apps, my 980X will still be slamming HSW hard.

Any chance you will be able to get that thing up to about 4.5ghz? I'd like to see the temps and voltages it requires.

And you actually think you will still have the 980X when Haswell comes around? You have the upgrade bug almost as bad as I do. 😉

Those are nice numbers at 4.6ghz...might have to upgrade too :thumbsup:

I have a feeling that you will jump back to 1155 when ivy hits retail.Intel made ivy with even better latency.If you dont need the 45gb bandwith I see no reason for anyone going x79 right now

You know me far, far too well, Edrick!

Stable @ 4.5Ghz with 1.320 Vcore. Running in mid 50's with the H60 cooler with HT off. With HT on, it requires 1.35 Vcore and runs in the high 50's under Prime95.

I couldn't even get my 2500k to run in the high 50s with my H60. Those are good temps and nice overclock on that chip. If the mobos weren't so pricey, I would have one just like yours.

I am really happy with my CPU temps. I think the larger contact area on the CPU helps dissipate more heat to the cooler block. It runs cooler than my 2600 did and about the same temps, with HT on, as my 2500K without HT.

As for the price, it really is not that bad. Newegg had a combo deal and free shipping (no tax). So I got both the CPU and MB for $550. If I went out and bought a 2700K and a good Z68 MB, it would cost me about the same. Plus I sold my 1155 MB and CPU for $250 to make up some cost.

-on the net it seems like the 3820's have got a bad rap because of crap es oc. or reviewers that reviewed them had no interest in the 3820 , but wanted the site hits.
-even HWC did a 3820 es review 2 days ago ,es chip built week 39-2011 but will be the same as retail . , stated as the 920 replacement then ran all the chips at stock speed during the review.,oc = same bs 4.7 needing 1.45v or something.using the oc software what must have spent all of 5 mins. on the oc. lol
-likely the same es used in other reviews.

 

[Edrick]

4.5Ghz @ 1.32v - 1.35v seems pretty good to me. I really do not put much stock in review sites that use ES samples only. I tend to wait for the retail review or just buy one myself 😉

Plus I am PCIe 3.0 ready now and I do not have to wait for IB 🙂. Bring on Kepler!!!!!

Edrick, I wonder how well this chip fares in games such as BF3. I would like to see the CPU usage if you ever have the time to test. (and if you have the game)

Well, I ran BF3 at max settings on a 64 player Metro map (full). I used the Win7 Performance Monitor to test this and my CPU usage did not go over 70%. This is @ 4.0Ghz and HT active. I know my 2500K was peaking at 85% on the same map and same settings (no HT of course). So clearly HT helps BF3 slightly and I do not have a CPU bottleneck on my system. I am limited by my GTX570. Oh, and my resolution is 1920x1200. I think I am going to try my hand at SLI now that I have a X79 system.

 

[Rvenger]

Yeah, would be nice to see if there is a bottleneck. I wonder how BF3 responds when HT is off.

I read that BF3 can use up to 8 cores. Not sure if that is true or not, but if so, then HT should help.
