I was wondering what is considered the best X2 cpu from the OCers perspective? IMHO, the 5000+BE at 3.1Ghz for $75 is the best buy. Anyone know of a better one for a good price? BTW, I already know about Intel's OC ability so lets keep it to AMD recommendations please. Thanks.
Best AM2 cpu for OCing?

stay away from the phenoms.
if I remember correctly, there have been several articles comparing athlon cores to phenom cores and phenoms have scored somewhere between 15-25% improvement per core. That should translate into a 3Ghz athlon X2 being more or less equivelent to a midrange phenom unless I'm mistaken.
Hard to find X2 5000+ BEs. The AMD Athlon 64 X2 5400+ Brisbane 2.8GHz 2 AM2 65W for $87 will hit 3.2GHz at cpu freq 228MHz with stock cooling and 1.37v for the most part. You can volt higher but will hit a pretty hard wall and need upgraded cooling.
Phenom OCs are approaching 20% with 790fx mobos.

I saw the 5000+BE at Compusa on Sunday some stores have product on the shelf. Gotta check the stores personally.
heyheybooboo, I have tried to get my 5000BE to 3.2 by raising the cpu and ddr voltage pretty high at 200, with no luck. Are you saying raising the fsb to 228 will do it with 1.375 cpu voltage? I am willing to try this, any disadvantages to raising the fsb? It will run 3.1 only at 1.425v with prime 95 for any length of time at 200.
I am a noob when it comes to OC.
OP, yet another vote for the 5000BE for a very easy OC with just one touch of the keypad in your bios. Go from a multi of 13 to 15, and instant 3.0gz. from 2.6, very stable.

I just picked up a 5000+ BE and 2GB OCZ Platinum ddr2 800 for $109 + $30 mail in rebate from TigerDirect. It's been 2 years or longer since my last purchase of a cpu. Still running my Opteron 165 and 3800 x2 939.

id get the windsor 4600+ X2 L2 512kb
http://www.newegg.com/Product/...x?Item=N82E16819103064
it has the same stepping as 6000+ and 6400+ and inherit about the same oc like it brothers.

I don't have a an X2 5000+ BE but from what I understand a little imagination, patience and tweaking will help you get your best OC.
Checking out a basic AMD AM2 OC guide is a good place to start. It will give you an idea of the terminology and the items you need to address in the BIOS to maximize your OC. In your case your best bet is going to be using a combination of the cpu multiplier and the cpu freq.
First off, any increase in the base AMD cpu clcok leads to an increase in the memory and hypertransport freq. If you increase the cpu freq 10% (or to 220MHz) you are increasing the memory and hypertransport freq 10% (so you generally have to reduce them to keep the system stable). With that in mind ....
Drop your hypertransport (HT) from x5 to x4
Drop your memory freq from 400MHz to 333MHz
Lock the PCIe freq to 100MHz
(This will give you the headroom for up to a 20% increase in the base AMD clock freq of 200MHz - or 240MHz.)
I like to write everything down in a spread sheet (and do the math before hand) so I know where I'm going but you may be different. It is also important that you download monitoring and testing programs which are typically listed in a basic OC guide (like CPUz, Orthos, SpeedFan, etc). Watch your temps closely! Now comes the fun part ....
After setting your HT and memory as above, pick a cpu multiplier (let's say 14.5) and increase the cpu freq to 205MHz. That little bump has got you up to 2.97GHz. Monitor you temps. Do a quick stability check and if you are happy bump the cpu freq up another 5MHz. When you hit a wall increase your cpu voltage to 1.375v - uo to 1.4v is safe (some folks go 1.45v). Keep bumping the cpu freq, monitoring your temps and checking stability. You will reach a point where going more than 1MHz is like beating your head against that wall
With a cpu multi of 14.5 and cpu freq of 220MHz you are really close to 3.2GHz. You will reach a point where a little volt bump to your ram or HT may help (some AM2+ mobos also provide for a SB volt bump). The best advice I can give you as you feel like you are approaching a hard wall make only single adjustments in the BIOS. If they don't seem to help, roll 'em back and try something else.
That advice .... and keep everything nice and cool

Unless you're using an unlocked multiplier, and haven't changed the HTT bus speed. If you're overclocking only by raising your CPU multiplier, then both your RAM speed and HTT bus speed will remain unchanged.
He meant raise the HTT bus another 5 Mhz higher, not the CPU speed.

Umm, no they don't. Your particular board/BIOS may, but the majority that I've seen (25-30, if not more) either call it the HTT bus, or even the front side bus, funnily enough. I don't remember ever having seen a BIOS call any bus "CPU Speed", for fairly obvious reasons.
You are splitting hairs for no reason and your attack is meaningless. Are you intentionally crapping on this thread and attacking me? You have offered no incite to the OP but seem to be fixated on me. From my original quote (no use of 'CPU Speed' in the context you use):
And perhaps you would like to back up your contention: the majority that I've seen (25-30, if not more) either call it the HTT bus, or even the front side bus ???

I'm not sure what your problem with me is, but you need to get over it. I haven't attacked you in any way. As a matter of fact, I've been much nicer to you than you've been to me. As far as proving a negative, that's not possible. I infact haven't ever seen any BIOS that designates either the HTT bus or the front side bus 'CPU Frequency', though like I said in my last post, your BIOS may very well call it that-- I've just never seen it, even though I've messed with >25 Athlon 64 BIOS's. Would you care to try to prove that I have infact seen it referred to as CPU Frequency?
And as far as threadcrapping, you seem to have a lock on that. The only reason I made my first post in this thread was for something called clarification.

On my Gigabyte 780G mobo, I have CPU Clock Ratio, Memory Controller Freq, CPU Host Clock Control and CPU Freq. Don't see anything about HTT like I used to on older mobos. Which one would be the HTT? I'm using an X3 cpu.

Okay, those are going to translate like this: CPU Clock Ratio= CPU multiplier, Memory Controller Freq= memory speed @ stock CPU speed (memory divider or multiplier, IOW), CPU Host Clock Control= this has to be your HT multiplier. You'll know for sure if it's got settings between 1x and 5x. And CPU Freq will be your HTT bus speed.
Hmm, I wonder if maybe AMD (i.e., Hector) issued an edict to all of their motherboard manufacturers that they wanted them to dumb down their BIOS's for the new boards? I say dumb down, since obviously your CPU frequency isn't anywhere near 200 Mhz, and all CPU frequencies are determined by multiplying the CPU multiplier times the HTT bus speed on AMD CPU's, and by multiplying the CPU multiplier times the FSB speed on Intel systems. It honestly wouldn't surprise me in the least if they did that.
Clarification ???
Here is a brief 'clarification' on the BIOS settings when overclocking the following motherboards (none include your designation of 'HTT bus'):
Asus A8n: CPU Frequency
Foxconn NF4 sk8aa: Cpu Frequency
ECS A780gm-a: CPU Over-clocking Freq
MSI K8N Neo4: Adjust CPU FSB Frequency
MSI K8N SLI Platinum: Adjust CPU FSB Frequency
MSI K8NGM2: CPU-LDT Frequency MHz
Abit AX78: CPU External Clock (MHz)
Biostar TA770 A2+: CPU Clock (Now that's funny!)
DFI LAN Party NF4: FSB Bus Frequency
Asus A7n8x-e Deluxe: CPU External Freq. (MHz)
Asus A8n SLI Premium: CPU Frequency
ECS Geforce 6100SM-M: CPU Frequency
Asus M3n78-vm: CPU Frequency
MSI K9A2 Platinum: Adjust CPU FSB Frequency
Gigabyte GA-M57SLI-S4: CPU Frequency (MHz)
Gigabyte GA-MA69G-S3H: CPU Frequency (MHz)
Gigabyte GA-MA78G-DS3H: CPU Frequency (MHz)
Gigabyte GA-MA790X-DS4: CPU Frequency (MHz)
Gigabyte GA-K8U-939: CPU Clock
Gigabyte GA-MA790FX-DS5: CPU Frequency (MHz)
Any questions ???
You should have quit when you were far, far behind ...
