Upgrading AMD X2 CPU

October 16, 2010 at 12:06:24
Specs: Windows 7, AMD, 4GB
I have a NF61S micro am2 SE motherboard running an Athlon X2 64 4200+ processor.
I was thinking of just upgrading the processor for under $80, so I went to the Biostar website and it lists that it supports only 5000+, 5200+, and 6000+ near the top end.
However when I go look up AMD's website for 64 X2 cpu's those models aren't even listed anymore. Now they have ones like 5600, 7550 listed. as well as some energy efficient models like 5050e.
I also did a search for other models I could buy and come across a 5800+ as well.

I'm just not sure which ones will likely work, or if I'll be stuck searching for an old 5200+ on ebay.

I presume you mean "NF61S MICRO AM2" or "NF61S MICRO AM2 SE"

It seems like they only list the Windsow Core x2 as compatable



But it list BIOS Updates to support newer CPU's, but does not fully define what CPU !

But it would appear 6000+ is the max on an AM2 platform, is it a viably economical upgrade considering you have to buy a USED CPU ?

Did it occur to you that you can *probably* overclock your 4200+ to between 2.60-2.75GHz for free?

If 6000+ is the max, can I likely use a 5800+ then...even if it isn't specified on the biostar site?

Yes I know I "could" overclock it more. I just dont.

The particular model I have is ADA4200IAA5CU

If it's not listed, there must be a reason.

"I "could" overclock it more. I just dont"

Probably because you don't know how. You have a CPU sitting in your case right now that's capable of 3.0GHz, why not take advantage of it? I'm only suggesting taking it up to 2.60-2.75GHz, that's well within reason. If you don't like it, just change the settings back the way there were then go out & spend your money.

Yes, but it could simply be the reason is that they don't update the info for old boards. It also says the board only supports upto 2GB of RAM but it runs 4GB just fine.

The reason I don't OC it is because I'm the type of person who sees things as having a the processor stamped with a certain speed for a reason, and that I wouldn't want to buy an OC processor either.

I don't know why the CPUs between the 5200+ & 6000+ aren't listed but I can only assume there's a reason. The 6000+ is gonna be a little hard to find & if you resort to eBay, there's always a risk involved. Your AM2 system is "old" by computer standards....AMD has already gone thru the AM2+ series & is currently on AM3. For approximately the same price as a new 6000+ CPU, you could buy an AM3 board & CPU that will spank the sh!t out of your AM2 setup.

As for your opinion about overclocking, you obviously know little about CPUs. For instance, all AMD CPUs based on the Brisbane core are essentially the same CPU. AMD brands them as 5000+, 5200+, 5600+, etc & varies their clock settings to offer CPUs in different price ranges, but that doesn't change the fact that they're all basically the same. For instance, the 5200+ is clocked at 13.5 x 200MHz (2.7GHz) & the 6000+ is clocked at 15.5 x 200 (3.1GHz)...the only difference is the multiplier. AMD locks the multiplier from being raised (unless you have a "black edition" CPU) but they do NOT lock the reference clock from being raised (the reference clock for ALL AMD CPUs is 200MHz).

Your 4200+ runs at 11 x 200MHz (2.2GHz). You can't go higher than 11x with the multiplier but you can change the reference clock from 200MHz to say, 250MHz. That will change the CPU speed to 2.75GHz (11 x 250MHz). Raising the reference clock has a domino effect on the other clocks (RAM, HT, PCIe, PCI, etc) so those settings have to be adjusted to compensate, but myself or someone else can layout all the recommeded BIOS settings. And understand that I am NOT recommending that you overclock to the extreme....I'm not suggesting settings that would push the CPU to it's limits or require an advanced cooling setup. I'm just suggesting a reasonably mild 20-25% overclock that almost ALL CPUs are capable of these days, usually without any voltage increases.

But hey, if you'd rather spend your money, go right ahead. Remember when you go shopping that the X2 6000+ MUST be the 89W Brisbane version at 3.1GHz...do NOT get the 125W Windsor at 3.0GHz.

Thanks. I'll likely do some searching to find a good deal on one somewhere.

finally got an official response from Biostar...

Yes, you may use 5800+ CPU.

We recommend to use AM2 Brisbane or Windsor CPU.

like jam said, don't get the Windsor at 3.0GHz. if you do, a heatsink/fan upgrade will be needed as well.

I'm back! (from a looooong time ago)

I just don't understand what purpose it is to upgrade that cpu to a slighty faster cpu for 50 plus more dollars especially on an outdated platform that AMD no longer supports. At least with an AM2+ platform you would be able to keep your ram and upgrade to a AM3 processor.

Iron Sharpens Iron.
