My FX-60 does 2.954 on aftermarket heatsink. I have read several reviews and these chips run stable as high as 3.2 on the STOCK heatsink. I am new to computer hardware but I wouldn't consider myself a noob. This is the first rig I have built in 5 years due to a change of hobbies. I may have missed something while overclocking so please inform. This is what I have and what I have done:

I purchased an FX60 from tigerdirect on January 10th for $1199 USD. I paired it with a large all copper ThermalTake Tower 112 heatsink. There are two 90mm fans screwed to the tower that each push ~70 cfm. I have two 120mm exhaust fans on my Stacker 810. I used Artic Silver 5 exactly as instructed. Cleaned surfaces with lense paper and rubbing alcohol and applied 3/4 BB of compound in center. Carefully installed tower and allowed it to spread the compound when it was screwed down. There have been plenty of cpu cycles to break in the compound. I use prime 95 to test for cpu stability. I specifically use the torture test with an 8k to 64K fft size. I run two instances of prime 95 [one for each core]. While the cpu primes away, I monitor the core temp with PC Probe 2 for the a8n32. In the bios I have determined the optimal voltage setting is 1.52 [hardware reported]. Continuing higher causes the temps to get too high [crash]. Continuing lower doesn't yeild eanough power [no boot]. To keep the mem out of the equation I used a 14x mult and a 211 htt [the ram is rated 219 stock]. It runs 24 hours fine @ 2.954 with ambient temp ~21ºC and all fans on max. Max recorded core temp was 46ºC. Other combinations caused errors in prime at 2.958 and higher. I tryed a 4x htt. I also tryed overvoltaging the htt from 1.2 to 1.3 and this didn't help either. At one point, I questioned the psu but while running prime 95, the gpu's are barely being used so I can't be running out of juice. I really expected 3.0 stable without H20 or freon. Any suggestions?

First and foremost; please don't keep the bulk of your writing in one large paragraph. It makes it very hard to read.

Second, the heatsink that comes with the FX-60 is on par with most aftermarket heatsinks.

Third, a lot of lower end chips are simply DOWNBINNED higher end chips.
I.e.; they had 100 that met FX-60 specification, 200 that met Opteron 165 spec; but needed 25 FX-60s and 275 165s--they'd downbin the extra FX-60s, and lock the multiplier.
And a lot of people cap out at around 2.8->3Ghz anyway; so that might explain everything.

Fourth, did you manage to write down the stepping on the CPU?

Also, if I remember correctly, most of the people hitting 3.2 Ghz on the stock heatsink are using massive voltage... something along the lines of 1.6.

How did you 'hardware determine' your voltage?
I'd go back to stock voltage (1.350) and see how high it can get.
From there, increase it .025 volts each time, and see if it can get any further. Increase the frequency in 50Mhz steps.

Also, set the RAM on a divider; and keep it down as low as possible. This will absolutely insure it isn't causing any problems.

Finally, how hot are the PWM ICs?

With dual core chips, they get EXTREMELY hot--make sure there is active air over them, they could be the root of your woes.

Also I don?t think that I have ever seen an FX60 do 3.2Ghz on air cooling, no matter what the voltage used.

You?ll be looking at a water setup atleast to possibly hit 3.2Ghz

First, I'd agree with Rich--it is illegal not to overclock an FX chip--hence the unlocked multipliers.

That was rude and uncalled for.

That's kind of the point of the FX series... the unlocked multipliers. They're basically designed to be overclocked ;)

Most of the dual-core A64s/Opterons overclocks to around ~2.8GHz (at least in here). The 3GHz+ overclocks are a very small minority IIRC.

The reason you topped out at 2.9x ghz is that X2s, and A64s in general are not production-line ready for 3ghz. Period.

AMD can bin chips to their heart's content and still not have a viable 3ghz part (just ask intel how their original 1.13ghz P3 worked out).

Of course in today's market, it doesn't matter, because a 2.6ghz x2 is still the best thing out there, from any company in the desktop space.

The A64 design is pretty mature at this point, so barring miraculous results at 65nm I doubt you'll see 3ghz (or at least anything over 3ghz) except occasionally in OC'd systems before a serious core refresh occurs, and the real benefit to further die shrinks may well be 'more cores' not 'more clock'.

Well I did say he has an awesome rig. Which he does. I just intended to try and lighten the mood a bit, as I'm sure we've all been in the situation where we've saved up, or ploughed lots of money into something, and then it didn't quite go as well as planned.

navecko, I apologise if my earlier 'tone' upset/offended you.

You're right that it probably isn't the PSU, PCP&C have a better image than the big G in a lot of peoples eyes, so it should be fine.

I'm guessing money isn't too much of an issue, so maybe have a look at a DFI motherboard? As they're THE overclockers. The a8n-sli is very good also though. As I'm sure you're aware, all of your stuff is basically, awesome, so if it isn't happening, then yeah, probably blame the CPU. The 3.0Ghz figure is just in your head really, 2.95Ghz stable is not going to actually concern you compared to 3.0, but I completely sympathise that you want 3. It's just, better.

Possibly sell the FX-60 and get an opteron? I'm sure the guys here could offer you the best stepping to look for to give the highest probability of a 3Ghz clock, and it would mean you had an awful lot of money left over to put towards better graphics... :)

Hope that makes amends. Congratulations on what is still a great OC, and on having (most probably) one of the fastest PCs on AT :D

Im not really sure what you were expecting to get. There has been many reports of people who cant get over 2.8. Im not sure its ever a good idea to buy the highest end chip if overclocking is your intent. Normally they are as close to the max as you can get.

2.95 sounds about right to me for a dual core, 2x1MB cache chip. You're lucky if you can get your Opty 165/170s to overclock at that speed without trouble.

That's about the limit without using water or some other exotic cooling solution. As long as it stays stable try to enjoy it. Myself, I don't apply crazy-high voltages in an effort to squeeze out a couple hundred more MHz.

Do you have a link to these reviews touting 3.2 stable on air?

Thanks.

There are several laws in AZ relating to NOT overclocking a FX chip.

Get a Vapochill Lightspeed and then come back if you still run into overclocking problems.

Some tips:

-Have you tried higher voltage? You may want to give it up to 1.55V (actual, load). Is 1.52V your load voltage or just boot-up voltage?

-PSU's are usually the #1 cause of an o/c limit. Is the PC P&C 510 a well-rated PSU (check reviews, etc)?

-ASUS supposedly cleaned up their act big time with the a8n32sli, which I believe uses 5-phase power converters for the CPU, but historically for awhile now, ASUS hasn't been the greatest overclocket due to voltage fluctuation and droopage (not to mention the traditional ASUS overvolt at stock voltage). I've had the best success overclocking S939 chips using DFI boards.

~3 GHz is what I'd expect for that chip unless using good water cooling or better (phase change, dry ice, etc). 3.2 Ghz on stock cooling sounds optimistic and every chip/batch/etc is different.

You run up to 1.55v on AIR if you are using a single core.

With dual cores, half of that.
(Half of the increase).
Usually 1.475/1.45 is the 'safe zone' for air cooling with dual cores./

Thanks for the responses. Here are my replies:

CPUZ tells me it is Model 3, EXT Model 23, Stepping 2, Revision JH-E6. I have no idea what these numbers mean.
This reviewer:
http://www.thetechzone.com/?m=show&id=498&page=5
Got an FX-60 stable at 3.2 and a windows boot at 3.4 on stock HS. His Model and stepping are the same as mine.

The voltage of 1.52 is what my hardware reports in the bios and what CPUZ tells me. The a8n32 board has a weird way of setting the vcore and the settings I chose aren't the same as what the hardware reports. I set the bios to 1.375 and +0.200mv enabled.

The voltage fluctuates. Is this normal. It doesn't stay at 1.52. Some times 1.49 or 1.55. Max Voltage flux +- 0.05. This is as reported by PC Probe and CPUZ 1.32

The PWM IC's [those things around the socket that control cvore voltage right?] on my board have heatsinks on them. They get somewhat warm but there is a lot of airflow through my case so I don't think they are out of spec.

Also, I may have overloaded my fan controller. It is rated 18W per channel. There are 4 channels. I have like 8 fans in my case and wired them to the fan controlled making sure not to exceed 18w per channel. It says to only use one fan per channel but I would think that if each channel handles 18W why can't I put 3 5watt fans on the same channel?

I Have gone as high as 1.600 vcore beginning from 1.350. It just gets too hot 56ºC and then reboots by itself. It won't boot below ~1.45. Also putting the mem on a divider doesn't help.

I know the 3ghz figure is just in my head but it would still feel better to get it from 2.95 to 3.0 than it feels to get it from 2.6 to 2.95. Maybe I just got some dirty silicon :(
I'll look into h20.
