@teppic and martini - FX6350 oc'ing upgrade from 8150

It may be that it relies on distributing most of the load across 4 (the reviews usually say the game is basically unplayable on dual core CPUs), with a lesser amount after that. Because of AMD's modular design, the 6300 has an extra module to play with, which might account for the big increase between the 4300 and 6300 despite the lower clock speed.
 
So maybe it uses 3 cores and due to the module design of Piledriver it doesn't work so well on the 4 core/2 module chip, but after that it's all down to speed. (Which I think is basically what you said)
 
It's difficult to say. You do see scaling on multi-threaded apps that use 2, 4, and 8 cores. I'm not sure of the cache level on the 4300, if it's significantly lower than the 6300 then that'd be another factor. I have Crysis 3, but no 8320/8350, so I can't check the core usage.

I do have Crysis 3 and also a 8350. But I wasn't getting on with it so I bought a 4670K (then a 4770K) and stripped the 8350 PC down for parts. So, long story short, it's not up and running.

1 pass of IBT isn't rock solid stable :p

But it's certainly a start.

Also, at 25 seconds, was that standard? Try Maximum.

Also, think you've got confused about PSU's, PSU's have multiple rails, it's the 12V that I'm on about, that can sometimes be a quad rail etc, I've never seen a hex rail for 12v, so check how many 12v's it has.

It has 6. I flipped the PSU 180 degrees today to give more cooling to the fan. It has 6 12v feeds, up to 28amps.

I've done 4 or 5 IBT runs, CineBench a few times, 3d mark and AIDA. I've been working for hours on getting it overclocked. Started to see patterns and correlations etc. it was standard IBT runs. I'll do maximum tomorrow. I'm sure it'll pass.

5GHz is very good going still.

I'm not sure what's happened to your drives though. In all the time I've overclocked (which has led to plenty of crashes/lock ups) with either Intel or AMD I've never once had a corrupted OS.

Nor me and I've been overclocking for over 10 years and had hundreds of blue screens, hangs, crashes, power offs, restarts. Anything you can have. I've installed OS on two new drives, backing up to the old two drives and got my old OS on them. I have 2TB of storage so its all good.

5Ghz does seem like more then a lot of people can achieve. I'm just nervous of giving it more then 1.6v and need to add a radiator if I want quiet running because the AF120s at full chat measure 80dbs at 0 distance and 60dbs at 300mm distance. Nt accurate but doesn't need to be, it sounds like a turbine sat next to me. Lol.
 
How many times do you guys run the IBT test? I've been leaving it at the default of 10.


I've noticed, my multiplier is flicking between 21.5 and 22. This started after a 4.6v spike on the RAM and SB.

Erm....can't be good???

20 runs on very high is more than enough. I've never once had a unstable overclock pass 20 runs of very high. Any more than that is overkill, will takes ages and puts your cpu/memory under excessive sustained pressure and probably shortens its lifespan.
 
Do you do any encoding LT?
I've been able to have 20 IBT passes be unstable when under sustained load, say encoding.

20 runs is a pretty good test of general stability, it's not going to randomly mess up.

The FX4300 has less L3 cache. However,Crysis3 does use upto 8 threads very well. It is one of the few games in which a Core i7 can do much better than a Core i5 in AFAIK.
 
I'd be interested to see how my overclocked 6350 did in that bench as I am seeing 50-60% increase in frame antes in world of tanks. I'm hitting 90+ FPS. Average is about 75FPS I reckon. Need to install FRAPS and run a test. That is 50% on my 8150 overclocked. Very impressed. :)

Also in this Crysis 3 benchmark there's a big increase in minimums too between the 6100/8150 and 6300/8350. It seems to be common in comparisons.

The FX8350 has a ~11% clock-speed advantage and a 27% advantage in the minimum frame rate.
