***official amd 83x0 overclocking thread***

breadturbo said:
Guuuuys, started OC'ing my 8320 today and so far i've got here....
4.8 (24x200) with 1.4v, socket temp 48.1c, core temps 38c after 4hours priming.
I've not yet messed with anything besides LLC (set to UHIGH) the multi the cpu and ram volts and the ram timings.

I also quickly tested 220x23 and that was stable with 1.428v,
I tried 220x24 but that needed 1.486v and got a lot warmer (57c socket, 48c core)

Welcome and good news that BT!

At what point does the core temp tell the truth? (it did read it was over a certain c but can't find it now) I assume im best still going by socket temp? and is 1.5v the max I could safely use day to day? getting to this point was very easy (like OCing an intel tbh)

Spec is... 8320, sabertooth 990fx r2.0, 8gb crappy kingston 1600mhz, my custom car radiator loop.

I was told the package temp was the one to watch but I feel the software is incredibly innacurate in the lower scale (20-40c). 1.5v is the most I would push on air, sounds like you got a good clocker there!

I would push it to see how far you get then back off voltages till you get stable and drop it a notch for 24/7 use.

Mines at 4.7Ghz and the temps are good.
 
Hm, package is even cooler. that tops out at 35-36c after priming a while.

Ive had a go at 24x220 :P with 1.48v, it was prime stable for around 60mins then threw up an error on core6, i think thats probably stable enough for me as I doubt i'll ever stress it that much gaming (when i should be working) :)

The only issue i have now is ram, im having to run it at 1330mhz as the next divider up is 1800ish and the crappy 1600mhz ram throws a wobbler.
 
Well as you own both an i7 and an FX, you can contribute to the realistic opinions on here. Most of the guys in your position can hardly see much difference when using the machines yet there are a few on here that would rubbish that even though they do not own an FX.

The performance comparison is more aimed at i5 users but it's nice to get a sensible viewpoint from people who own both brands. If you get time it would be nice to compare your i7 with a single 290 to your FX rig and show results. Feedback of playing the same games would be fantastic!

Some people have actual emotional investment in 'their' company. I can live to be a million years old and will never understand this type of mindset. If I'm forced to fumble for an answer I'd say this behavior stems from the late Cretaceous period where they used to swing around trees with 'their' groups, and never really evolved much beyond that point of view. That's just one man's opinion :p

Ignore the marketing BS and kiddies programmed to parrot buzzwords and buy what suits you. If it's cheap, cheerful and totally adequate you want, grab the 83x0. If you want to spend the whole day running benchmarks and posting them online. Grab an Intel. Both CPUs will give you excellent value for money.

I'd agree. I'd say I'm hard pressed to see the difference between my intel and AMD systems in anything except benchmarks. In day to day gaming they are both great.

In terms of general system "snappiness" I'd actually say the FX system is superb. Applications open instantly and one app that usually makes most PCs sweat a bit when opening it is Curse client for my WoW addons. The FX8320 opens it almost instantly as does my 3930k. My previous i5 2500k @ 4.8GHz took quite a few seconds longer (same SSD and windows 7 ultimate).

Interesting and I agree with you. I see zero difference in the two systems during gameplay. Nor do I have an Intel at hand to compare the opening of apps. With my new SSD stuff takes a second or two to open. FireFox literally a second. Usually instantly.

Not played WoW for a good while now so not bumped into that issue. I've not really bumped into any issues that made want to spend more on what I've paid for my 8320. And believe you me, I'd dump the 8320 and go to Intel without thought had I run into a persistent issue.

In fact, my next chip I might actually go Intel to mix things up a bit. I started on the C2D (e6300), went to E8400, went to 956BE and now 8320. Might keep it fair buy another Intel next. And Nvidia too for that matter as my last two cards were both ATI/AMD. :p
 
Stick around this area (CPU) regulus and you will see what debates we have to go through (generally the same robots trying to rubbish the FX).

I think I will comprise a list, just need breadturbo to feedback from the last post. The way I see it the proportion of users that have both systems can tell little difference bar a benchmark % or 2. This just reinstates my opinion that when buying for value the FX is actually far better than people give credit for.

I loved the tek syndicate roundup that turned performance on the head when the FX matched or beat the intels when streaming was applied. God knows how they would perform if the software was designed and compiled with AMD in mind then utilised all the cores properly.
 
Hi guys, great thread!
Had my first attempt at over clocking my FX8350 managed 4.7 GHz (4715 MHz) by just upping the FSB and no increase in voltage.
FSB is currently on 235, 240 and my computer would struggle to boot, 236 and one core would drop out in prime so 235 seems to be the sweet spot just now. Saw a healthy bump in my Unigine Valley score from 2755 to 3117.
Might look at a small increase in voltage tomorrow see if I can get any further. Anyone have a rough idea how far a corsair H90 will take me?

Good going bud. I find 235 FSB is the limit on my CPU. Bump the voltage and watch your temps. The H90 is ok. What temps and what voltage are you at currently?

petertr2000 said:
Hmm, anyone got any ideas why my voltage isn't dropping when the clock is set low on idle?

Its staying at 1.404V regardless of whether the multi is 22 or 7

Hi Peter. Your voltage will not drop unless you set it on auto or you use the offset feature. If you manually set it in bios, that is what it stays at even though the CPU downclocks if you have the power saving settings enabled (e.g. Cool n Quiet).

That'll be the one.

Any tips to convert a manual to an offset. Whenever I try this, I tend to end up blackscreening and having to take the battery out!

To be fair, I haven't performed this on my AMD system. Works well on my intel system. Best way of doing it would be to note down the voltage you use manually for a particular overclock. Next set it to offset with the smallest positive increment you can set.

Next boot up and open CPUz. Check voltage immediately and see what the system is feeding the CPU at idle and very briefly at load. If for example your CPU is stable at 1.4v manual setting and when you boot up in offset mode, it gives it 1.45v at load, then you can go back to bios and set offset mode with a negative -0.05V. Similarly if it gives it 1.35V, it may not boot at all or if it does, go back to bios to give it +ve offset of 0.05V.

If it isn't booting, I'd be tempted to try some increments of positive offset to see if I can get it to boot. Sometimes, the system puts silly volts through the CPU while doing this so WATCH THE VOLTAGE like a hawk. If you end up requiring negative offset, remember the same amount is deducted from your idle volts, so if you shave off too much, it won't be stable at idle. It is a balance to be struck here.

True dat;)

Been sort of saying this for a while. The Intel "fanbois" pile on a large amount of cream to the debate. Confuses the hell out of those on a tight budget for a decent rig for 1080p.

To be fair mate you have. It is a shame as theres a few more like yourself or who have jumped ship who are not positively spreading the news though.

I am interested to hear from our new friend to this thread and see if he finds the same..

Yeah I'll push it a bit further tomorrow.

Should I be setting memory frequency to the speed of my RAM or as close to as possible? Will setting this to auto be unstable? Think I've currently got it set a little lower than my RAMs frequency as there wasnt an exact match.
