Upgrading CPU processor in HP desktop a6112n

February 26, 2010 at 18:23:29
Specs: Windows 7, athlon x2 4000
I have an aging hp desktop a6112n. I want to upgrade
the CPU to squeeze more life out of it, and increase
fps/loading times in games. My system is stock psu
(300 watts) with a 8600 gt, and 2 gigs 6400 DDR2.
The motherboard model number is M2N68-LA, and is
listed below. It's an AM2 socket type


The HP site says i can upgrade to a max of 5600
(89w). My question is that when i'm shopping around,
do I need to make sure the watts match up (89w)?
Can i upgrade past that 5600 mark, despite the hp site
warning? Any recommendations on compatible cpu's
are welcome, i'm willing to throw down 50-100 dollars
to make my computer a bit faster

The problem playing games is not your cpu, it's your video card. You would see a lot more performance out of that machine for gaming with a newer video card. Here's a list of recommendations, but keep in mind, you will also need a new psu.

If you decide to go with a new psu too, look for one that has a single 12 volt rail with 30 amps or more on the 12 volt rail. Corsair makes a good psu with those specs. You can find them on newegg.com.

Your link doesn't work.

This site uses a program that chops off the visual display of a URL if the URL is longer, and replaces it with a shorter link here with dots at the right end of it, that is supposed to link you to the full URL..
Sometimes it makes mistakes and chops off the actual URL. .

This works..
Go here:

Enter this upper right
Product: a6112n
Question: M2N68-LA
click on >>> to the right of those boxes.

That yields you the a6112n support page

(Your Product Specifications state you have a:
Athlon 64 X2 (B) 4000+ 2.1 GHz (65W)

"...i'm willing to throw down 50-100 dollars
to make my computer a bit faster."

If you don't have the money to spare for both a cpu and a video card / possibly also a power supply, if you're presently using onboard video, you'll definately notice the most difference if you get the latter.
Plus - you can probably use the video card and possibly any higher capacity PS in a future computer as well. )

"The HP site says i can upgrade to a max of 5600

You can use one that consumes less power, but don't get one that consumes more than that !
Some of the AM2+ mboards are well known to have circuits that will BURN OUT if you install a cpu that consumes more power !

However, it appears you can install up to a 6000+ 89 watt one (there is also a 6000+ 125 watt version).
By the way, the boxed set (cpu plus heatsink/fan) 6000+ comes with an EXCELLENT heatpiped heatsink.

Post #6

"....there many different configurations of the M2N68-LA (Ivy(ASUS), Narra(ASUS), Narra2(ASUS), Narra3(ASUS), Narra5(Pegatron), Narra5L(Pegatron), Ivy8(ASUS)) used by HP; all with slightly different specs."

" Processors: "

"Narra/Narra2 supports X2 up to 5600+ up to 89 watt Socket AM2 Processor (currently AMD Athlon™ X2 6000+) "

That's assuming HP's bios version recognizes the 6000+ properly, of course, which it may not.

NOTE that there newer X2 cpus that consume 89 watts or less, but it is quite likely this older mboard's bios version cannot recognize them !

If you DO go for installing a better video card.....
...adding to the info grasshopper supplied

If you're presently using the onboard video, you certainly WILL get better fps rates in games if you install a decent video card and use that instead.
Your same mboard ram amount will perform better, in addition to the ram amount presently being shared with the onboard video probably being freed up for use by Windows - sharing ram with the onboard video as much as halves the ram's max bandwidth - max data transfer rate - when the onboard video is disabled (usually installing a video card in a PCI-E X16 or AGP slot auto disables the onboard video, and in that case, the ram installed in the mboard is then no longer shared with the onboard video) the ram can then perform to it's rated max bandwidth - you notice the difference most when you use a program that benefits from the greater bandwidth - e.g. fast moving video, or the video in a more recent game.

"My system is stock psu (300 watts)"

Your power supply must have at least the minumum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer.....
In most if not all cases, the max capacity rating of the PS is an intermittant rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

If you need to get a PS with more capacity, you can usually replace it with any decent standard sized standard ATX PS.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.

wow! thanks for your explosive advice and time

On new egg they have limited older athlon X2's, they only
sell the boxed 6000+ @ (125W) with attached fan/heatsink,
i'm not sure whether to risk it at that higher watts. The
direction i'm heading towards now is just getting the 5600
(89w) on ebay, they have multiple users selling it at $50.

Question: I have a socket AM2 motherboard, and I'm getting
confused with the "AM2+" motherboards. My logic is that
the AM2 + is a newer version and before I buy the CPU it
should say it supports AM2, and not only AM2+? Just out of
curiosity, can I get other processors like the X3 phenom's or
X4 as long as its AM2 supported and under 89 watts?

When i bought this computer ~3 years ago it was made to
be a mediocre gaming machine. It amazingly still plays the
games coming out there today with some at medium
settings. The thing that holds me back the most is the CPU,
CPU dependent games I lag more in compared to similar
users with the same 8600GT. I also don't meet most
minimum requirements because of my slower CPU
@systemrequirementlabs. The 8600GT has lower psu load
than other cards and is probably the max I can run on my
stock PSU.

I'll be back down the road if i decide to revamp the
psu/videocard, thanks for your input!

grasshopper - that's a good reference !



Oops - I've only see the 6000+ 89 watt sold as just the cpu.

If you look under Socket AM2+ motherboards here:


you will see that M2N68-LA is in the same "family" as other Asus M2N68 and M2N68 whatever AM2+ mboards.
If you click on the Asus M2N68 and M2N68 whatever AM2+ mboard models there, you will see that some support cpus > 89 watts, some support Phenoms.


- M2N68-LA is NOT an Asus retail model - it's an OEM only model - supplied only to brand name system builders, perhaps only to HP - there is no support info for it on the Asus web sites, and no cpu support list for M2N68-LA is available there, or on the HP web site.

- some AM2+ mboards definately have circuits that will BURN OUT if you install a cpu that uses greater than about 90 watts. The fact that other Asus M2N68 and M2N68 whatever AM2+ mboards can use greater wattage cpus does NOT necessarily indicate the M2N68-LA can.

- The M2N68-LA has a HP bios version on it. You are limited by whatever info the HP site provides, and whatever cpus the HP bios on the mboard will recognize properly, unless you can find third party known-to-work info about that. HP isn't known for updating a bios version such that it can support recognizing more types of cpus - but Asus does that. There are usually no new bios updates after a short after the mboard was first used by HP - their updates are usually only bug fixes, and there is usually little or info about whether a bios update supports recognizing more cpu types in the release notes for the bios update.

- It may have a different I/O (Input/Output) chip on it than other Asus M2N68 and M2N68 whatever models.
- Mboards in HP and Compaq models often use a Phoenix overall bios version; most mboard manufacturers, except for Intel, use an Award or AMI overall bios version. You can't successfuly flash a Phoenix bios version with an Award or AMI bios update, and visa versa - you have to replace all the code in the bios - flashing the bios usually does NOT flash the boot block bios part of the bios code - that has to be replaced as well as the rest of the code. It can be done, but you have to find special known-to-work instructions.
- Because of those things, you should never use an Asus bios update on a mboard with a HP or Compaq bios version, or visa versa, or a bios update for one Asus model on a similar Asus model, unless you find specific info about how to do that that has been confirmed to work.

So - you could take a gamble and buy a cpu < 90 watts newer than a 6000+, but there's no guarantee it will work properly in your mboard - the mboard may not boot at all !

Phenoms perform better much better on AM2+ mboards when all the DDR2 ram is 1066mhz. The 64X2 6400+ and lower cpus cannot run the ram faster than 800mhz.
The memory controller is built into the cpu in both cases; it's not built into the main chipset.

You often can't compare cpus based on only the mhz speed at which they run.

E.g. If you have the

Athlon 64 X2 (B) 4000+ 2.1 GHz (65W)

the 4000+ model number is an AMD approximation of how it compares in performance to an original Intel P4 cpu - equivalent to a 4ghz P4, rather than the 2.1ghz it runs at.

Same goes for 64 X2 models up to and inc. 6400+ .
6400+ ( 3.2ghz ) hasn't been available new for at least a year, if not two years, and there is only a 125 watt version, that I know of.
