what is the best fastest am2+ cpu

[nelly999]

hi I have just reaquired my old am2+ system and I would like to know what is the best cpu I can get to put in it, I am abit old school and I am keen to see what the old dog can do, but I have been on intel for a long time now and I am not upto speed on amd, even if its 6 core or fx..... thanks

Have a look at the CPU support list for your motherboard.

On the top of my head, I recall the fastest CPU you can have on the AM2+ is the Phenom II X4 945.

What is the motherboard model??

Every Phenom II CPU will work on AM2+ including the Phenom II X6 1100T.

However,whether the motherboard VRMs are upto the task is another question.

 

[stulid]

Depends if the board can take the higher tdp phenom II chips.

isnt is the 940x4

isnt is the 940x4

Strictly speaking, yes.

But that's ignoring that AM3 chips work on many AM2+ boards (It's not strictly all, there was a 790FX board I've seen that just flat out would not work with Phenom II's, it was an older high end one too)

Fastest possible CPU on AM2+ Motherboards is the Phenom X4 9950 Black Edition but as mentioned depends on your motherboard. Can get them on ebay for about £50

hi the board is an asus crosshair II formula, I don't know about vrms I guess that's the extra power for the chip, I have checked the cpu support list and am guessing that the 6 core 1090t would be the best, there is only 1 fx chip on there which was a dual core, but that list is from 2012...

 

[HalfBakedJake]

Your motherboard supports 45nm technology so may support the Phenom II X4 940 Black Edition

 

[CAT-THE-FIFTH]

The Phenom II X4 and X6 will work with that motherboard.

 

[HalfBakedJake]

Just noticed that. Check http://www.asus.com/Motherboards/CROSSHAIR_II_FORMULA/#support for the chips available

That's not remotely true

Phenom II X4 940 was an AM2+ chip, DDR2 IMC only, same as the Phenom II x4 920.

These chips won't work on AM3.

They were the fastest AM2+ chips.

And I'd be worried to find you not get a Phenom II X4 940 for 50, I sold one for about 30 quid

EDIT : My friend ran a deluxe one of those 790FX ROG boards and it flat out wouldn't run with a Phenom II, even though it clearly stated it would, he changed BIOS chip, tried different Phenom II's, was all up to date, just wouldn't work for whatever reason.

But then there's plenty of people who ran similar 790FX boards and it worked fine.

He was running the old 690 SB IIRC.

My Bad I thought it was a AM2+ motherboard

AM2+ was Phenom II (Where it originally launched)

Even some AM2 boards can take a Phenom II, but it's far from common.

would a 6 core work better than a quad even if its slower because of the extra cores....

 

[Martini1991]

would a 6 core work better than a quad even if its slower because of the extra cores....

It's X GHZ per core, not X GHZ divide by cores (If you're thinking that)

 

[nelly999]

so a quad at 3.2 ghz all the cores run at that speed....

 

[Martini1991]

Yes, all cores will run at 3.2GHZ.

GHZ isn't a set performance scale though.
1GHZ of 1 CPU from X range could differ from another CPU at 1GHZ of range Y.

 

[nelly999]

so a 6 core running at 3.2ghz would technically be faster....
