AMD 5000+ Black Edition Overclocking Results

Runs on air.

It sits on a window ledge (shielded by a blind so hte sun doesn't hit it), the window is very slightly ajar.

120mm at the front, 1 at the rear. Large silent 550w XClio PSU draws a good amount of air out also.

Case temps are ~20'c and the northbridge reports similar figures with the cpu just ~25'C at idle even running 1.5v at 3.46GHz! Very cool, literally.
 
holy, that is cool, i cant wait to split my w/c up to seperate the heat between the xfire and cpu cause its running crazy temps atm as reserator isnt totatly up to the job as its passivley cooled at 1 point i stuck the fan from the top of my antec to the reserator lol, hense the big push for splitting, as i simply cudnt go back to air. what cpu did u have before the black edition ? as the 5000 only has 1mb cache doesnt it(much difference from the previous), but i was thinking of upping as there 65nm, but phenom is tempting just not yet... You have any pics of your rig?
 
Single core Opteron 144 @ 2.8GHz, socket 939 on ASRock DualSata2 board.

The Opty had 2MB cache but simply can't match the dual core for response in windows!

The 5000BE will last quite some time at these clocks, the cache drop from 1MB to 512k is only about 100-200MHz difference in real world terms... in other words you can't tell.

A rock stable 3.5GHz with a high FSB is plenty of power, that said I'll be pushing for 3.6 on air just to see if I can. :D

With this mobo I have plenty of time to wait for Phenom to mature, but even then I only browse, game and do a little office work so dual Athlon is plenty of poke of me.
 
very nice :) im hoping for around 3.5 with this new loop dunno if thats pushing a 6000 too far but soon find out i guess just have a play with the fsb and multi and make sure it has plenty of juice cause my chip is very power hungry lol, guess thats 1 thing the 5000BEs do quite well at. am more intrested in a tri core though makes more sense that quad :D but all depends on price and how bad new games get in terms of performance , i know *** xfire cards could do with updating but cant justifiy buying a slower pair of cards that are new tech lol when my cpu lags just a little, so would u recomend the 5000 ? to a pc gamer/overclocker?
 
Surely youll get higher results on a multi of like 10-13 instead of 16-17 with just a higher fbs. I rembember reading on a review saying generaly stay between 9-12 on the qx6800 when they were overclocking it. Gues it might be different for amd.
 
yeh its a little different especially on am2 as i said before people say there seem to be a kind of barrier on the fsb around the 222 ish mark, so I have read all over the web as i used to have the same proplem but a bios update later and unlocked Htt settings so letting me drop to 800mhz rather than 1ghz when clocking let me break it :), just hope the same happens with phenom once the teathing problems are gone :)
 
Well this CPU either has a 3.5GHz wall or it doesn't like the inflated HT speeds (hopefully the later).

I've found a modden bios that allows me to modify the HT divider so I will try that tomorrow.

The HT limit seems to be just shy of 1.2/2.4GHz at this kind of clock range (3.4-3.5GHz). This confirms what Tanner has said about 222HTT (FSB)!
 
thats a shame Edleake as thats been going pretty well but also i find the best combination to get more out of the fsb (note this is on the k9a platinum) is to drop both the HTT to 800 mhz and the multiplier to 14 this is how i obtained my 3.26 ghz but then after this my temps become a problem as i have to crank up the voltage more as I am using the 6000 which is 90nm. I will keep trying to break the 3.26 ghz barrier am stuck at once temps have been delt with and will post some cpu z screens , but it has taken a while for me to get this bios with all the options i described unlocked as i have had the board since october time last year and only in the past few months have been able to try for the higher speeds, so maybe if all else fails will have to wait for a bios release, hopefully not as long as mine took :D
 
Slight hijack as I'm new to this and need some advice.

I have the same chip and have raised the multiplier to 15x so I'm running at 3Ghz. Unfortunately my motherboard (ASUS M2N4-SLi) has its vcore locked. It'll only let you set lower vcores not higher which is a pain in the arse. Other than that particular nuisance the BIOS is quite overclock friendly.

My core is idling and stable (prime95) at 21 celsius so I've got quite a bit of room to get that multiplier up higher if only I could apply more voltage to the CPU.

Is there anyway to unlock the Vcore settings in BIOS or do it through windows or whatever?

I really can't be arsed buying a new board as I haven't had this one for long although I'm willing to listen to board recommendations if thats the only way.

Sorry for the hijack Edleake and thanks.

I'm having a problem too. I can't seem to get a stable multiplier higher than 15x whilst I am able to increase the voltage - I tried 1.5v and 16x and it simply wont run. What else can I try changing with this?

The recommended voltage for 16x is apparently only 1.375v. Of course this is going to depend on other factors but you're going too high too fast.

1.4v should get you running at 16x easily enough. Keep an eye on your temperatures.
 
To be honest with just multiplier alone 1.4v is stable at 3.4GHz!

However I hit a wall thereafter so the multi is out of the question, voltage above 17x doesn't matter for me.

With stock 1.3v my chip is stable on purely multipliers up to 3.2GHz.

With the introduction of FSB/HTT I can drop the mutli and retain 1.45v up to 3.47GHz but then both the HT link and multi become a problem - I can't go higher on the multi and the FSB is pushing the HT speed to close to 1.2GHz to be stable.

I found a BIOS that opens up a HT divider so I can drop the multiplier down from 1:1 to 800Mhz or even 600 if need be. I believe this will give me a lift past 3.5GHz. :)
 
Right the bios is flashed and I've set the divider to 800Mhz.

So far so good, I'm hitting 250HTT/FSB, will keep pushing, I've even dropped the volts one notch to 1.464. Notice the bus (HyperTransport) is now **** on at 1GHz instead of crashing out at 1.2GHz+. :)

I'll push for 300! :D
 
Damn it seems as though my limit is (3490MHz) 3.5GHz at 1.5v.

I've tried 1.54v - 1.58v - 1.6+ and they all reboot on windows boot. :(

I'll try the multi again and raising the HTT along with NB chipset volts.
 
Instead of try and make 3.5GHz stable I've opted to tweak 3.4GHz stable and fast.

The 100MHz isn't worth the push if I can fettle the ram at a slightly lower voltage and fsb, same goes for the chip which I've got stable at s notch lower volts (idles at ~30'c). :)

Its better in the long run. I used to run my PC so much on the limit that even 1 more FSB would be completely unstable etc, these days I just find the limit then back off a lot so it's ultra stable.
 
thats pretty close on for 3.5 thou Edleake, its a very nice clock especially if u paired it with some tight ram timings :) nice going dude its still quicker than my 6000 lol and was a lot cheeper all on air as well what are the temps at the 3.4ghz?
 
Load after an hour of CoD4 is just 44'c which is mad!

Idle of around ~30'c.

System/northbridge temp ~22'c.
