AMD x2 5000+

[diddle]

I've been able to OC it to 3.13ghz on stock voltage, 24/7 stable. (240fsbx13 locked multi @ 1.296v)
I tried to OC it more today and it doesn't seem to want to do anything over 240 FSB.
I've dropped memory clocks, HT clock and put the voltage up to the 1.41 limit of the x2 series (according to the thread on here)
Temperatures seem fine, even though I'm not really sure. BIOS reads ~40C when i'm in the bios but when I get into windows it reads between 20-25idle and about 40-45 load.
I've tried FSB between 241 and 260 and nothing seems to work.
It loads into windows, but fails every single prime95/orthos test.
And sometimes won't even load at all.
Is it just a limitation of the chip or my motherboard?
At the temperatures i'm allegedly getting I should be able to push it further.
If I touch the heatsink after turning the computer off it is pretty much cool to the touch.

maybe is the chip, maybe the motherboard, but my opinion. altough is cool, try with another heatsink

Try these settings

It don't show my voltage, but I have it set at 1.408v.

When I was tinkering with my athlonX2 5200 somewhere in cpuid/cpu-z/something I found it was listed as 3.0Ghz max. I was able to push it to that frequency, but just 25Mhz more and the cpu would encounter a temperature bug. The bug would randomly make the temperature stick to either 100c or -100c. While stress testing it would occasionally go to 100c, and I would be lucky if all I saw was the temperature jump very fast before crashing. The only reason I noticed this at all was that I was able to get the the chip to 3.1Ghz stable(one boot), but the temperature was stuck at -100c. I thought nothing of it until the next time I booted the chip crashed, and thats when I started to watch the temperatures when it crashed and noticed the temperature spikes just before crashing.

This information won't help you push your chip further, but it is something to think about while overclocking. As a sidenote somewhere(again I forget where) I found information on my cpu listing my q9450 as 3.8Ghz max, and that was the wall I encountered. It can run 3.6Ghz just fine, but at 3.8Ghz I have to push some questionable voltages into the chip.

Ah I found it! In my pcprobe2 theres a DMI tab on the right, and inside there is information on the cpu where it lists my processor as 3.8Ghz max. No doubt the same information can be had somewhere in cpuid.

Try using a lower mutli, then try uping the FSB if it still doesnt work then its probably the mb, if it works then its probably the limit for the CPU. Also if it a brisbane core those temp readings are probably wrong, very few read the right temp

 

[diddle]

What can I safely assume about the temperatures then?
Or should I just blindly overclock and hope I don't melt my CPU?

 

[MilkyWay]

i am certain its one of 3 things, the cpu is actually only going to hit around that speed its just one of those chips every chip is different i heard some x2 5000+BE could hit 3.4ghz mine is capped at 3.2ghz

heat in that case download and try real temps and core temp to check the cpu temps

or its the mobo sometimes this can limit the cpu speed because im sure its limiting my cpu as once i got 3.3ghz then later i could only reach 3.1ghz stable now its 3.2ghz stable max

ram can be a limiting factor but not so much on the amds and not so much eitherway

 

[MilkyWay]

1.45v is the max id run an x2 at but ideally you want it lower

Some people believe that if you add 20 degrees it will be the right temp, i have also heard about its CPU temp+room temp. I dont think i would trust any of it, if a cpu is too hot it will error in orthos. So when i had one, i clocked it to a speed that i knew was stable(like 3ghz), then just keep upping the volts(up to 1.5V is safe), at each stage ran prime for 20 mins and write down the voltage and the temps, when it fails, look at the temps for the preivous run then take 5 degrees off(10 if you want to be really safe), look at what voltage gives you those temps, this is you max voltage for your cooling. Now apply these volts and see how far you can push the cpu, once you find your max start lowering the voltage to see what volts it needs to run at that speed

 

[diddle]

Well, 240FSB seems to be the limit of the CPU.
Even after a BIOS flash, lowering memory speed, HT speed, HT link speed and upping voltages on CPU, chipset and NB, it will not stay stable at anything over 240.
Even lowering the multiplier and raising the fsb, it isn't stable.
Thanks for your help guys, 3.13 seems to be the limit of my chip.

 

[Andy_007]

sounds like a mb limit, not a cpu one, I havent come across a brisbane with a fsb wall that low , it is possile but unlikely, all my previous X2's(4000,4200 and 5600) all ran past 320 FSb

 

[Flyordie]

Yeah, thats a NB limit. I ran into that limit on my current rig. (10x275). I have it set to 300FSB in the BIOS. Yet it won't go any higher than 275Mhz on the FSB.

 

[cdawall]

your on a pretty bargain bin mobo...

those chips go higher i had one

but you need much higher voltages 1.55v to get to that i posted @4ghz on that chip @1.8v

 

[Clutch442]

Yeah but that's the BE, I don't think he has one of those.

Nice numbers though, I can't get past 3224

 

[diddle]

Yeah, I'm not saying it's a bad overclock.
I just know there is some more performance left in the chip. Would maybe upping the NB voltage help?
I've only ever upped it .1v cuz I don't really know how that would do with .3v+ into it.
North Bridge is running on 1.09V and the HT is running on 1.2V
And no, this is a standard x2 5000+

Would it even be worth upgrading to a newer CPU without upgrading my motherboard first?
I'm not /entirely/ sure this is a motherboard issue. upping the NB might help, i just don't wanna kill it.

 

[LittleLizard]

i think ur mobo support newer phenoms with bios udpate

 

[cdawall]

Yeah but that's the BE, I don't think he has one of those.

Nice numbers though, I can't get past 3224

he doesn't but they still clock about the same brisbanes tend to clock alike

Your right it is actually a pretty good overclock for the voltage you have it running it at, i had to push 1.46V to get 3.2 and 1.42V to get 3ghz. Upping NB voltage may help, did you get any more fsb from increasing the voltage from normal to +0.1V? ,If you did then theres a good chance that +0.3V will help further, If you didnt get a improvement then it probably wont help but try it anyway, it shouldnt kill it. If your going to upgrade you cpu make sure u get a black edition so you dont run into a fsb wall. You could try the new X2 7750 Black.

Finally broke the 240FSB mark.
Had to turn off cool and quiet.
It was weirdly named so I didn't recognize it at first.
Now, the only problem is my temperatures are too high.
I have it set to turn off at 65C and it's turned off a few times during prime95 runs.
So what are good heatsinks for amd?
I have about five inches of clearance in my case.
Five being about the minimum, there may be more but I don't wanna push it too much.

 

[Andy_007]

Well done, how much are you willing to spend for a cooler?

 

[diddle]

About 50 US.
And I'll buy some Arctic Silver 5.
I'd like to spend about 50 total, but I'd be willing to go as high as 60 for quality.

I added .08v into the CPU and .2v into the NB and it still wasn't stable. (@ 250x13)
It booted into windows, did tasks fine but failed prime95.
From 1.296 stock and 1.09 stock respectively.
36.99 for that cooler is a pretty decent price. I'll order it within the next week and hopefully I'll be able to push this further.
