Figured id see how far i can push my X2 6000+ on a stock HSF and 6 case fans (90mm) in a full tower case.

first test is just FSB - it defaults at 200

Running now at 210.1Mhz - 3151.2Mhz

gonna keep pushin just the FSB till i hit a wall then start on everything else

Specs

A64 X2 6000+
Abit KN9-Sli
4gb OCZ DDR2 800Mhz ( 2 x 2gb stix )
Geforce 6600 GT OC
3 HDD's ( 80 , 80 , 500 ) all sata II
Ultra X-Finity 500w

any bets on wether i fry this proc or not ??

Well, Im sure that CPU could probably hit 3.2Ghz all stock but will probably be pushing on temps. But if you start pushing the Vcore up, I would highly recommend better cooling

well now im at .........

Bus speed = 215Mhz Core speed = 3225.4Mhz

but as i was lookin in the BIOS , the multiplier is at 15x and thats the max. now if my thinkin is right , goin lower ( say 14.5 , 14 etc etc ) is going the wrong way, right?? if this is the case then ........... THIS BOARD SUX !!!!!!!!! lol

My temps are stayin around 45C , now but at 220FSB it acts quirky and fouls out on superPi , i'll give the V a nudge an see what happens

Yeah, Muli's cant be upped on new AMDs you could go lower but you will need higher FSB to get same overclocks. Run Orthos Stability test and 3.2Ghz to see if its 24/7 stable (if thats what your looking for)

Welp , after messin around for an hour or two , i started lookin round the web and it seems that even with better cooling the highest O/C i found was 3.8Ghz. The avarage was where i hit allready at 3225Mhz so i donno ...............

I'm gonna try , but i think its the just this CPU . If this is the case , i might just buy a diff one. I was kinda hopin to push it to some better speeds than 3.2

Hi Mace, nice to see you around again.

I think you have your expectations set too high for that CPU to be honest. I doubt you'll get much over 3.2Ghz with any kind of air cooling, even with more volts.

For better performance, you could try lowering the multiplier and upping the FSB, see how high you can get that

well i got it to 3300Mhz but after running 1M in super Pi , i tryed 32M and it started havin' fits , ima try some voltage tweakin but i think 3200 is my best on all stock .............. GAY AMD

Yea, AMD's suck ATM. Intels Core 2 Duo and Cor 2 Quad and raping AMD.

I beg to differ!
Just because the Conroes are better doesn't make the AM2 CPUs suck.
I bet you I can take any RAM you have and OC it higher than you can on the AM2 platform versus your Conroe platform.

Ah, yes you probably could. I meant on a price/performance ratio

No worries.

Keep this in mind HTRN:

While a 200MHZ gain doesn't seem like much of an overclock, you are at the top of the food chain for an AMD 64...if you had started with a a 5000+, you probably could have pushed it to 6000+ speeds...and that would have seemed much more impressive!

You bought the FASTEST AMD 64 on the block...wich means you got one of the "Best of the best" cores when they "Speed bin" the cores on the assembly line.

How that works, is they test each cpu for a certain clock speed, with the default voltage..if it passes there stress tests, it is marked as such, and "Locked" on the multiplier permanetly (You can lower it from stock..but you can't raise it, only the "FX" versions are unlocked up and down, you are stuck with a max of 15x)

Anything that doesn't cut the mustard at that speed is passed down the line until it passes (It may pass as a 5000+ for example) sometimes CPU's from the same "Slice" of silicone can end up with drasticly different speeds.

Typicaly, the ones towards the center of the wafer tend to be more "Pure" at the atomic level and are the premium ones..the ones at the outer edges of the wafer will have a few more imputies,and not clock as high...

That is based on what I have read over the years, but it may be more urban legand than anything, not having worked at a fab plant, I cannot verify this, but it does seem logical.



When overclocking any CPU, I drop the multiplier at least one or two notches below stock, and use a HUGE memory divider, to isolate the motherboard from the ram and CPU, allowing me to fine tune the board, and find it's maximum FSB (Try using 14x or 12x)

Then I know when I start overclocking the CPU for max speed, I am not hitting an artificial "Wall" caused by the Ram or Motherboard!

Once I know I have the settings and motherboard voltages set that allow for say around 250FSB, then I will go back to the stock 15x and 200 FSB, and start pushing the FSB up again, and when I hit the "Wall" again..that is when I will start adding CPU voltage!

One of the biggest isues most new to AMD 64 overclockers will run into is "HTT" overspeeding..it is a ratio that needs to be adjusted to maintain stability when overclocking.

The stock HTT Multiplier is 5x

5x200=1000MHZ (This is the max speed you want it to run at when overclcoking)
5x220=1100MHZ (This will typically make the motherboard unstable)

What you need to do is change it to 4x

4x220=880MHZ! (You won't loose any real world performance by running slightly lower than stock speeds, but it will make the system stable)

Max HTT for FSB settings:
5x200FSB=1000 (Stock)
4x250FSB=1000
3x333FSB=999MHZ

There are also other critical settings that effect a motherboards stability at increased FSB speeds, such as North Bridge voltage, LDT voltage, etc..without having them "Tuned" properly, people blame there "Lame" overclock on the CPU!


Typically, I sugest at least one notch above stock for all voltage settings, and then "Isolating" the motherboard and ram as I described earlier...you should shoot for stabilty at 250FSB using the 12x multiplier first, since you know your CPU can run at 3000MHZ

To give you exact settings to try would take forever, these are the "Highlights" and the rest is up to you...it takes time and experience to become a master of your motherboard..I won't even get into the Ram setings at this time...it is even more confusing...just set it for now with a big divider (1/2 speed) and let us know how far you get!

Read these articles, they are older, but the theory is stil sound, pay particular attention to the section on Voltages, the chart on page 2 was "Eye Opening" for me back in my early days.

Quote: I got the motherboard up to 300MHz HTT quite easily by adjusting HTT Multiplier to 3x. I had no luck trying for more as the board does not boot up after 300MHz HTT

One last thing..you will get a higher CPU overclock by using better cooling of course, 50c is the max load temp I like to see!

The stock cooling can be improved by using Artic Sliver thermal paste instead of what came with it..just clean off the old stuff, and apply it evenly, no thicker than a sheet of paper..a razor blade works well for that, or an old credit card.

Other tips:

Disable "Cool and Quiet" in the bios, and set all the fan speeds (CPU, NB, etc.) to run at 100%, they often will have a "Max Temp" set at like 50c, try lowering them to 30c, that will make them run 100% all the time!

An aftermarket cooler can increase max OC speeds often another 100-200MHZ, depending on your CPU...Anandtech got a 2.93 GHZ Core 2 Duo to OC to 3.7ghz with stock cooling, but reached 3940MHZ with the Thermalright Ultra 120 Extreme, you might reach 3.4ghz with one


AnandTech: Thermaltake Big Typhoon VX: Does VX Rule Cooling?

WOW , THX Necro, im gonna print out all the stuff you posted ( or alot of it ) and bring this rig out to my test bench so i can mess with it easier. I'll keep the stock cooler for now , but i'll pick up a better one for later. I'd be happy with being able to hit 3.4 or 3.5 and run Pi 1M /32M and a couple other benches. Really not even looking for 24/7 stable just an hour or so stable and beating the upper avarage 3.25 /3.3 would be shiny

Thanks for taking the time to post all that VERY VERY usful info , i know it took alot of time , and im very appreciative of it Bro.

Well..just to give you an ide of how other people have done with this CPU..here is what the OC World record databse says, it includes LN-2, Dry Ice, Phase Change, Water and air cooling results:
