Safe Vcore for AMD X2 6000+ 89W Windsor

Hi all,

I have a AMD X2 6000+ 3000GHz 89w Windsor on a MSI K9N Ultra.
I have been overclocking a bit and am currently running 3.3GHz @ 1.45V

Is this voltage safe for the CPU for everyday usage? My temps are below 60 C at the moment and I am getting a new cooler soon which will take them down to about 45 C.

Also what is the maximum safe voltage to run everyday?
As a reminder this is the 89w windsor version ]http://products.amd.com/en-us/DesktopCPUDetail.aspx?id=548&f1=&f2=&f3=&f4=&f5=&f6=&f7=&f8=&f9=&f10=&f11=&f12=], not the 125w.

Also when I started the pc up and had the vcore set to auto in the bios is was set to 1.35V

Thanks for any advice

I think your there. I can't remember if max was 1.4 or 1.5. I think it was 1.5, so as long as your temps are ok you should be good. (I'm assuming those are load temps.) As long as you don't mind the chip burning out after 5-10 years you should be good with 1.45.

Thanks for the answer, I don't plan on keeping this PC for longer than 2 years even so it should be fine.

I am just wondering if I can get a higher overclock :( 
Will experiment tonight.

It's a pity my ambient temp is about 34C at the moment...

Actually for that chip an ambient of 34 is just dandy. Pretty nice actually.

Remember, more voltage doesn't necessarily make for a better overclock. Windsor's can handle 1.45 volts, anything higher is not really recommended but I've seen people go higher for a one shot. I would say for everyday, max 1.45 V vcore. Take it up to 1.5V for a one shot, but bring it back down for everyday use.

My FX-62 (Windsor) was running at 3.15Ghz @ 1.45V everyday and ran for two years that way.

Sounds good, don't think I am going to get a much higher overclock than what I am running now.
I shall try a once off run and see what my max is, perhaps a 3dmark run or two.

The biggest problem you'll have is K8 was only good for about 3.4GHz on air. (and even under water not much more then that.) 3.3-3.4 is probably the best your going to be able to do. With work you can probably get 3.5, but 3.6+ isn't going to happen unless you get lucky. There is a reason why AMD developed K10.

Unless he's in the southern hemisphere in which case it IS summer. I hope your points are understood however. Brisbane or Windsor, I still think 1.5 was the max you'd want to do.

Haha, ya I am in South Africa. Its pretty hot here at the moment.
Ok well when my new cooling arrives I will try bump up the vcore a bit and see what speeds I can get.

Thanks for the help guys

I wouldn't go past 1.5 for any length of time. And as I said, you might have hit the top end of what that chip can do.
January 6, 2010 5:53:59 AM

yeah I think I will stick to 1.475 to 1.5. Overclocking is very time consuming, only going to have time to play around next week again :(

I dont think you know what processor you have.

The 6000+ Windsor is 125w, not 89w. The 89w version is 3.1ghz, not 3.0ghz and it's called Brisbane.

Remember it's winter and your ambient temp will be at least 10c higher in summer. AT LEAST.


actually the Windsor 6000+ F3 stepping had an 89w TDP

hard to find, AMD never documented it on their site

http://www.bcchardware.com/index.php?option=content&tas...

(i know you guys won't trust a wiki entry but here it is anyways)
http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_micr...

funny about the wiki is that i had one of these 6000+ 89w Windsor's, the voltage is normally lower

and newegg's now deactivated 6000+ Windsor 89w

Hey guys the link in my original post directs you to the processor on the amd site. They seem to be pretty scarce, but I much prefer this over the 125w.

Anyways, since it is the 89w version is it still safe to use 1.5v or less?

Thanks

Best solution

The voltage you can use doesn't change with the heat output of the chip. This depends more on the process used to make the chip. (90nm vs 65nm, or SOI vs HKMG.) The reason you have an 89W chip instead of a 125W is that yours was binned to run stable at a lower voltage. By running it at 1.35 instead of 1.4V, the amount of heat generated is lower. AMDs 90nm SOI process is safe to handle 1.5V. Even the EE 45W CPUs.

Thanks for the help, nice to learn a little more about these things.

You are right, interesting. Thanks for the link. :ouch: 


yeah it was weird when i was OC'ing it and i was looking up the normal voltage on AMD's site and mine wasn't matching the auto setting until i found out it was an 89w part

@ OP: as above have said, this won't affect the max voltage, only having the brisbane one will
January 7, 2010 12:50:22 PM

I didn't know this cpu existed either, as my friend has the 125w one. Then I was just browsing on ebay and I came across it.
I don't have the cooling at the moment for the 125w so it was perfect

Hey guys,

Here are some of the results thus far:

The cpu voltage is actually set to 1.45 but it tends to read a bit lower than I set it.

System specs:

MSI K9N Ultra
AMD X2 6000+ 89w :) 
MSI 8800gt OC
2x2gb ddr2 800 Apacer
2x1gb ddr2 800 Apacer



It seems stable at those speeds, I am running prime95 at the moment to make sure.
Temps are around 55 on the cores at full load.

I tried to overclock my 8800gt but I have had no luck, even if I change the core clock by as little as 5-10 mhz then it artifacts and freezes.
The gpu temps I recorded were a maximum of 73, which is high but I am still using the stock cooler :( 
Time to fiddle with memory timings...time consuming...
January 8, 2010 2:28:30 AM

Ok, so it's not stable. Failed prime95 after 3 hours 46 minutes.
Now the question is will an extra 0.025v solve the problem or should I lower the fsb a notch or two :( 

How long should I run prime for? Ive read at least 24hours

How long do you game for? I'd want more then ~4hrs of stable operation. I'd shoot for 8-12. I've already said all I'm going to say about Vcore and OCing for this thread.
January 8, 2010 6:03:33 AM

For my previous oc on my 4200+ I ran prime for 20 hours. Anyway, I shall spend more time fiddling
