x4 VS x6 in price and performance

post #1 of 14
Thread Starter 
Hello guys and girls, my first post.
I'm trying to decide whether I should purchase a
AMD Phenom II X4 965 3.4GHZ Black Edition $170.00
or
AMD Phenom II X6 1055T(2.8GHz) - AM3, 9MB Cache,125W $198
or the cheap option:
AMD Phenom II AM3 955 Black Edition (3.2Ghz) 64-Bit Quad-Core CPU $158

Currently I'm using a BE 3.2Ghz Dual core and I have had some bad experiences with it. Unlocked extra 2 cores, to find that I had massive screen tearing on desktop, icons changing color and bouncing around the desktop, toolbar disappearing changing color and programs failing like a huge animated circus on the desktop... fun times.

I disabled the 3rd core which fixed the problem. So I guessed I was in that unlucky 20% that had a faulty core. Until earlier tonight, when the same thing started to happen again. So I had to ditch yet another core back down to dual core. Now I'm pretty sure that's a warranty right there, but I could be wrong. Anyway I should be able to get a refund of $115 (approx) and if not I'd still like to get another CPU regardless.

I Overclocked the dual core to 3950mhz sucessfully, haven't done a huge stress test on it (12 hours) but did run for about 30mins on Prime95 no errors. This was my first attempt as well, upped multi to 17 and FSB to 245 (? i think), didn't change volts or ram or GPU yet.

Any suggestions?

Stock will most likely come from UMART, as these guys are good cheap and fast and close to home: http://www.umart.com.au

Why would you get a refund?
You bought an X2. Two cores are generally locked for a reason.
The chip functions with two cores and that's exactly what was advertised. Anything extra is a bonus.

If you want an X4, save some cash and get the 955. They have the same potential and unlocked multipliers. If you need a little more multithreaded performance, get the X6.

Pretty much what beers said. The difference in gaming is minimal for most games for x4 -> x6. I would go with a x4-955be to save money and OC the same as the x4-965. If you do more multi-threading and such then go with the x6-1055t.

So what's the difference between the black edition and the normal edition?
I was told the black edition generally have a 20% failure rate on cores. So 80% chance to unlock extra cores, or does that apply to ALL chips?

So if that is the case then I got in the extra unlucky 4% (20% of 20% = 4%)

Completely false.
Black edition simply indicates the CPU has an unlocked multiplier.

Phenom X2/X3, Athlon X3 all start off as quad core CPU's.
If a core or two are defective, they are deactivated and sold as lesser parts.
If the L3 cache is defective, it's disabled and sold as an Athlon.

The situation is when you have a particularly strong demand for a certain part in the line. Once this occurs then in order to fill the gap, the CPU's will be simply tested for basic functionality and shipped out. This may mean that perfectly functional L3 cache or additional cores become disabled. Also, you may have particularly good yields and not have many defective products, therefore will have to also fill demand with functional but locked features. This is the reason why people have success with unlocking cores and L3.

There's not warranty claim on the dual core, Is WORKS as a dual core which is what you bought it as

Look at the price difference between the quad and the hexacore and then decide if you would like a 2 extra cores for that difference.

Established already thanks.
I should still be able to get a refund being that I want an upgrade and it's only new. Easy for the supplier, smash it with a hammer claim it's defective and make 2 lots of profit. Haven't you guys worked in retail before?

Depends what you want to use the PC for. For gaming I'd go for the X4 965. $12 more than the 955 is worth 200MHz and will probably OC more. X6-not sure what you need 6 cores for at this stage maybe some pro apps.

Amazing how much repeat business you get when you go all out for customers eh?

I made a ton of commission selling car batteries to mechanics/sparky's back in the day, but then I probably had the highest amount of warranties the company had ever seen as well.
Thank god they didn't put 2 and 2 together... well it pretty easy to fool rednecks.
Screwdriver + hammer, hammer screwdriver through one of the plates inside the battery, take it back to base, stick it on charge. . . . BOOM. . . ya ya ya warranty. Give the mechanic a brand newbie.
