AMD FX 8320 analysis

My Haswell runs 4.75GHZ, that's a high OC, no delid.

In the same club, 4.6ghz without a delid. Could perhaps run higher but this is my 24/7 with a 30 minutes of overclocking, not even pushed.

The three 4770Ks I've used have clocked to a maximum of 4.1, 4.3 and 4.5GHz. Maybe the next will do 4.7GHz...

Yes but your an exception

Everything you have seems to be better than anyone else's

Not including the R 290

The budget i just had which was £850-£900 i could have gone intel but after having an 2500k and i7 3820 and reading so much about haswell and ivy needing delids if you want to clock high etc i decided to try FX out.
And im glad i did

Even if at 5.0Ghz its slower relative to Intel and within your stated budget?

The delid thing is only relavant if you want your ivy/haswell to hit a clock higher than 4.5-4.6Ghz as most do that with a simple multiplier and slight vcore bump.

From what i gather delidding might net 100Mhz and isn't really worth the risk in terms of voiding warranty.

I was thinking about doing this for my 3570k because I'm capped at 4.6Ghz and I reckon 4.7Ghz will clear me of any prospect of a bottleneck using crossfire.

Perhaps people should try more than one guide when OC'ing. Haswell OC is more about knowing how it works, and adding other stuff than just Vcore.

But this is offtopic.

Well if you buy a top end Asus or MSI board they give you an overclocking guide card for ivy and haswell with the board. Its very simple just following the instructions. In my case 4.5Ghz instantly.

Of course if you have the time and want to squeeze extra performance then pll, vdroop, ram timings and all the other stuff can be thrown in. But with tweaking I only managed 0.1Ghz extra lol. (4.6Ghz) Admittedly the TIM is likely the main reason but I doubt the chip would reach much higher than 4.7GHz even on the best water cooling rig..

I got more for my budget going AMD than intel

Asus rog board always wanted 1,if i went intel i would have had to get a budget board which looks cheap and tacky

Able to get custom water for my AMD

could have got the matrix 7970 @ £240 but decided not 2 after OCUK and so many bad reviews from latest batch plus was overkill for me

Ended up getting a Corsair AX760I psu,if went intel would have only got something like a 500w bronze psu

And that came in @ £790 which made the wife happy and gave me some browny points aswell

Thats a golden chip. Can you run that stable in BF4?

I'd include it to be honest, doesn't black screen and it does 1200MHZ

In all seriousness, I don't lord my stuff over people (I mean anyone can get my stuff if they want to, it'll only take a few weeks of saving) I couldn't give a toss what people run.

Also, ASUS rog due to the Hero VI is cheaper than it is on AMD (But lets not let facts get in the way AMIRITE)

I did a lad a 700 quid build recently, I squeezed a 4670K (H81 board, as that part he can update in future, that unlocks a crap ton) 8GB RAM, 128GB SSD, 2TB HDD, GTX670 etc) into it, that system will fly.

 

[Martini1991]

I can run that all day long, encoding etc.

4.6GHZ is my sweet spot, 1.3v.

My first 4670K could do 4.6GHZ but it needed the same volts that this needs 4.8 for.

I don't use guides, I just overclock.

I don't have the same time I used to (Like when I achieved my 4.375GHZ 24/7 Thuban back in 2010)

 

[teppic]

My 4770K refuses to be stable above 4.5GHz no matter what I do. Temps are fine, 60-70C under load. It's been the same with others, though the one at 4.3GHz needed 1.35v for that, which is pretty high.

 

[Martini1991]

I've only used 1 4770K.
Just put it to auto 4.4GHZ as I couldn't be fussed messing about and the lad hasn't had a single crash.

GTA 4, ARMA 2, Crysis 1, Oblivion, Skyrim, Supreme commander.... There's loads...

The 4670k would easily manage a rock solid 60fps given enough GPU power, the 6300 would manage them at 60fps but not a rock solid 60fps with no dips in the frame rate.

In arma 2 a 2500k will only get around 45 fps when things are happening. The game runs so poorly on Intel you can't notice the fx is marginally slower...

I'll let you into a secret i use 1.48v to hit 4.6Ghz. Temp's hit 100oC sometimes I hit 103oC and it throttles. (briefly and after hours of play)

If you want 4.5Ghz I suggest with those low tempatures you should try 1.46v and work the voltage back. As long as your temps are below 100oc under load it wont throttle. If you try this let me know if it works.

Seems hot. I sit around 40c while gaming with 600rpm fans

Ivy takes higher voltages, Haswell would need very high end cooling for 1.46v I think. The recommendation is usually 1.35v max for water cooling.

The FX won't be marginally slower if it comes down the CPU as it's a lightly threaded game.

To be fair, I don't recall massive problems playing on my Thuban.

EDIT : HOLY COW I WOULDN'T BE PUTTING OVER 1.45V IN MY CHIP! That is NOT a stable chip as fair as I'm concerned.

It probably isn't really 40, you know given the duff sensors 'n that.

Well the max with ivy is 1.4v and I go higher, but i'd use the thermal loading as a better guide. (Your chip and cooling may allow you to go higher) If you can keep the temp below 100oC under stress then who cares if its hot. The problem with ivy/haswell is well documented in that the cpu doesn't give up its heat to the water cooling loop because of the TIM. So increasing the cpu fan speed does nothing, infact the cpu water rads always feel at ambient i.e. not utilised....
