Hey all... my first post in these forums smile.gif

I have just ordered an i7 3820 chip awaiting it's arrival. Previously had an i7 920 (2.66GHz) with a Noctua fan which pushed to a stable 3.6GHz without breaking a sweat..... hoping for some magic out of this chip.

Just hope my MSI motherboard (only ever had Gigabyte and ASUS) can do the necessary magic.

I have read a lot and it seems you can quite easily get 4.3/4.4GHz with just some quick multiplier settings, but as I also understand, that tends to bump the Vcore voltage up by more than really required.

What I would like is a 4.5 or 4.6GHz stable overclock, RAM permitting and with lowest voltages possible, got a high performance Zalman CPU cooler on it's way.... wish me luck biggrin.gif

Its the best chip for the money, as the next step up (i7-3930k) is almost double the price.



As you will see from this picture, Ive bench marked every multiplier oc from stock 3.6ghz (100x36), and 4.3ghz (100x43) all the way up each multiplier that was stable ( I have psu issues) until 4.875ghz.



I will update this list with voltages once I get my new power supply. The above temps are AVERAGE during the benchmark, they are not full stress temps.


4.3ghz WITH SPEED STEP and Core parking is achievable with ALL AUTO VOLTAGES, meaning an Idle voltage of around 1.072v. Thats with all auto settings and its 8.5% faster than stock.

This is the LOWEST voltage you will get for any given speed speed step/turbo or otherwise. To achieve more than 4.3ghz it requires you to change the BCLK, and with BCLK, the voltages cant be brought down as much using speed step. I've this system in stock for for 6 months, then one day (2 weeks ago) I decided to overclock. Ive spent id say 60-80 hours messing around with this crap. I'm happy with what I found. I'm sure HomeCinema has spent even more time.

A happy medium is 4.5ghz or 4.75ghz , as you get 13.7% and 16.6% increase in performance without a lot of extra heat. If you want maximum speed, the 4.875ghz doesnt require that much more vCore than 4.625 - 4.75 and you dont get really any more heat production.

Once I get my new psu, I think my daily overclock with be 4.75ghz.


I dont have HomeCinema's benchs yet. But It seems

Hey can you turn off turbo, and bench a raw 125 bclk, 125 strap 40x multiplyer (giving you 5.0ghz) but without turbo or Speedstep on? Then do the Performance Test 8. and either post your results like i did above. Or in Performance Test 8 File->Save Baseline. This will save a file with PTX extension then I can import it into my Performance test and add you to my graph. That way I have full system info and avg temp readings

and 5016@2058 I worked out how to get the ram speed up and stable smile.gif








thats all your getting for now......Happy new year dude nerdsmiley.png
post #1950 of 6508
So I've had a 4.3Ghz overclock using a Sabertooth X79 motherboard stable for some time now. (Just set Manual Turbo Freq to 43 and let the motherboard do the rest, 9+ hours of prime with perfect temps and it's nice and stable) But recently I checked CoreTemp.exe and under frequency it constantly says 4300.00Mhz and wont drop sept maybe to 4299.00 or something. Before when I was testing the OC stability with Prime95 it would spike to 4.3Ghz(or did cpu rendering etc. anything cpu intensive) then if I turned off Prime it would drop to a 1.2Ghz frequency if I wasn't running anything. My temps are Core1-4: 34-27-34-27C. And I can't really tell if they're higher now then when my frequency would actually display properly that it dropped. It's doing the same thing on CPUZ and CoreTemp.

*Just set everything to default clocks (3.6 Turbo @ 3.8) and it is doing the same thing. Everything is default/reset on motherboard. Will display at 3.7 or 3.8 constantly.
Cpu load is like 0-1% running core temp and everything in the background so I know nothing is running. Checked thoroughly. And CPU gadget is showing the same 0-1% usage.

Is this a bad thing? Is it always running 4.3 now? Can I fix it? How did I mess it up in the first place? PLEASE HELP redface.gif Thanks!
