No problem. I'm expecting the biggest differences to be with largely productivity related stuff with a load of multi-threading like rendering type of stuff.

If the AMD feels just as responsive or does a good job then that's positive feedback we like to see. Bearing in mind the chip is just a smidge over £100 we equally want to hear if it lets you down and how it has done so.
Sorry Th0nt I missed this
I'll see about sorting a few runs out next time im back at work.
If im honest there isn't much difference at all in the two, there are a couple of games that favour one over the other mind, BF4 seems to run better on the AMD, and Arma 2+3 run miles better on the Intel (down to single core pseed I imagine).
I run both systems on cheap (yet pretty good) catleap 27" 1440p monitors.
The work one runs at 60hz, and my home one is oc'd to 120hz.
Thanks breadturbo. Sounds like you are enjoying it which is all that matters but even better if we have another vote on the 'not much in it' comparison opinion. If it can be up there with an i7 on heavy multi-core activities and perform equal to an i5 in a chunk of games then it just cements that for it's price point it really is a no brainer unless you have that extra cash.
Funny really as in the parked cores thread one guy posted he feels his cpu (intel) runs smoother with more cores active at a lower clock speed. Surely this is what all the AMD guys have been saying all along - yeah inferior IPC to intel but if the software uses all the available cores right it performs very well.

Hey guys, just taken the plunge and decided to move from my 4670k to an 8350, wanted a new challenge (and actually managed to make some money selling off my old mobo and processor to my friend!)
So far have managed to get my 8350 to 4.8Ghz prime stable at 1.45V using the Asus overclocking guide, though temps did get very high during that run (around 66C). Looking at this thread, people seem to recommend using AIDA64 so doing a run of that now and temps are hovering around the 50C mark. Testing BF4 next
I have noticed that many people on here increase their clocks by raising the FSB in conjunction with the core multiplier to get the same clock. Is there any particular benefit to doing this or is it another way to skin a cat?

From my research I found that raising the FSB came at a much lower temperature than hitting the multi. So basically for my 4.9ghz bench stable (and I ran the torturous Asus Realbench 2.0) I could only achieve it with a balls high FSB and my 20.5 multi. If I raise my multi any more my CPU becomes unstable and temps will soon see the PC locking up.
I was given some advice the other day from a mate of mine who is a bit of an expert with overclocking and he basically told me (this was for my Xeon but I would imagine it's similar in practice to AMD) that I should lower my mutli to the lowest setting (this is a Xeon 1366) and then start cranking the bus at 5mhz intervals. Once I fail to post or get into Windows take the highest stable setting and then start working on the multiplier.
Which tbh seems like sound advice. He also told me that bclk or FSB was not about how good the motherboard was but more about the CPU itself.

Ah ok, will have a crack at that later this evening. Fingers crossed will either be able to raise my clock or reduce temps!
Had a go on BF4 which ran amazingly (after I reinstalled C++... why are there all these problems???) at 99fps without mantle which I'm very pleased by, was only running at 70fps on my Intel. Will go on to do some poorly threaded games later (read WoT)

Also, does only increasing FSB reduce need to increase core voltage?
Soldato
You will likely need to add voltage yes. I just found that I needed far less on the FSB.

Working really well, now got the bus frequency to 260 with a multi of only 18.5 and now got vcore down to 1.44V. Whats the max bus frequency its ok to take it to?
Edit: Also, I'm using the Asus ROG Crosshair Formula V. Just wondering if anyone uses the second (4-pin) +12v attachment at the top of the Mobo and if it makes any difference to stability?

I have the same RAM, what are your memory settings?

I have updated the bios to the latest for the Crosshair V Formula Z to see if I can set the RAM voltage (I had to have it on auto in my older bios version or the system would lock up).
This has proven far more unstable than the previous version. It isn't allowing as much FSB play and my NB and HT link frequency are stuck at 2200MHz no matter what I do. Going to even 201, 202 FSB doesn't even post. I am able to get to 4.8GHz and 5GHz fine with multiplier alone but I want to have the ability to adjust NB and HT link frequencies and also use FSB overclocking to an extent.
Might roll back but not sure which bios is most stable. I am on win 7 ultimate.

I'm using the ones quoted on OcUK website - 11-11-11-27, 2133Mhz (or close approximation) but at 1.6v
Soldato
That's a nice FSB value you got. I would be interested in your cinebench result then as my overclock at 4.8 with just 220 will compare to see the difference.
Associate
The only problem with 260 is that core6 throws a slight wobbly after about half an hour of prime and comes up with a rounding error. Not sure if thats an issue or not, haven't tried gaming with my raised FSB yet. Passes AIDA64 nicely though and only reaches 60C now on prime!
Edit: Just did a cinebench CPU test and came up with 760. How does that compare?

It's not bad. The magic number for a FX8 is 800. If you can break that then you've climbed everest
It took me 5.2ghz. Some get it on lower clocks but man alive, it literally took my rig to crap its guts out to get there.

Just take a peek in the official thread:

I got 758 with 220fsb and multiplier ~4.8Ghz

Now sorted core #6! Just wanted a little extra voltage I think. Now running at 260 Bus freq, 4.82Ghz, 2087Mhz ram (little shy of the 2133 its rated at..) and a North Bridge at 2350Mhz.
I did have a trial at 275Mhz Bus, gave a nice boost in cinebench up to 775 but it didnt seem to like prime or AIDA64 at all, so have taken it back down to 260 for stability. Not sure if extra voltage would cure it? I have managed to boot to windows with a bus of 300 but didnt last long there.
Very tempted to try for 5GHz as Ive just this minute realised that the temperatures I thought I was getting (around 65C) were actually the socket and the CPU itself was only at 56C after an hour of prime... rookie error I know!
Edit: Also, looking on the SPD tab of CPU-Z, it appears as though the XMP profile for my ram @2133 is in fact 11-12-12-28 @1.5V, rather than the 11-11-11-27 I am currently running, though at 1.6V. Should I swap to the values in the XMP profile?

It will reach 5Ghz it just starts needed lots of voltage to become stable. A nice balance of FSB, multi somewhere between 4.7 and 4.9 with best temps will be where you can run day to day.

Thats what I'm thinking
Cant argue with 45C and 75fps in a heavy 64player BF4 game! (Without mantle enabled)
Soldato
Hey man glad to hear you're having fun
I can't remember what my max FSB was. I'll have to have a play soon

Looking good cwgk.
I've currently got my 8320 stable at 4.6Ghz with a v-core of 1.4v but im struggling to get 4.7 stable at all.
I'm using a combination of multi and fsb but I might try lowering the multi back down to 18.5 and just try increasing the fsb after reading the above.
Do you think its worth a shot?
I also cant set manual memory timings at all, I have to leave it all on auto or the system wont post. I'm using a sabertooth
