AMD Phenom II 955 x4 and ATI Radeon 6870

[haxartus]

The new 3 letter batches of Phenom II overclock extremely well (at least compared to before). 4.5Ghz on air is perfectly doable, and even beyond that. I'm not so sure that the i3-2100 is better at that point.
And you can always get an AM3+ motherboard and put the Phenom II on it.

4.5 on air with a Phenom II? lol?

4.5 on air with a Phenom II? lol?

With a 955BE on 1.6V. It still needs a pretty good cooler and an extremely good airflow, but it's doable.

Good luck with that on air and keeping below 62C. Friend has his at 4.4GHz on a Corsair H80 with 1.57v and still hits 58-59C with insanely low ambients. Hell it's not even completely stable lol.. Common overclocks for Phenom II 9xx's is 4.0-4.2GHz on air.

4.5+? Yeah.. maybe on liquid or DICE.

As I said, the new 3 letter Deneb batches are quite good. There are some improvements to the manufacturing process. 4.2Ghz is also possible on 1.45V.

There's no improvements to them..Otherwise they'd be listed with a new revision but they're not and are still C3. The problem with Phenom II's and air is obviously the low thermal threshold and regardless of the airflow you still can only cool so much.

Spend some more time on Xtremesystems or Overclock.net and you'd see this. New batch doesn't mean manufacturing differences.. Only a new revision does I.E. C2 to C3 revision Phenom II's.

There is, it's just not clear what it is exactly. They just require a bit lower voltage for a given frequency than the old batches, which makes them better for overclocking.

Even then I doubt they're hitting 4.5GHz or more on air lol At least... not from what I've seen of recent overclocking threads on OCN or XTS. 4.2GHz is still the common cap for all Phenom II X4's on air. 4.3-4.5GHz is definitely doable on liquid cooling while 4.6+ is typically on DICE or LN2.

So sure if by the sheer luck of god that you received a golden binned chip, you may get 4.4GHz on air stable but I highly doubt any more from what has been shown.

So far the only K10.5 Quad Core based CPU that commonly overclocked to 4.4-4.5GHz on air are the Phenom II Twkr editions that made a brief appearance in the past.

You can get to 4.6 but it gets too hot. 4.5 is doable if you have a good cooler and airflow.
4.2Ghz with 1.45V is also possible and with a good cooler you won't get beyond 40-45C.
Though there are still old batches being sold, so it's pretty random if you will get a new or an old batch if you order it online.

Proof? and not just ONE occurrence of it. I also expect them to be on air cooling with temperatures listed in a screenshot. Otherwise, I've already provided enough proof of the opposite

Here's even more:

I'm also unlikely to believe this as well since you have yet to provide the batch #.

It's not mine but I don't have a reason not to trust the person who got it.

Oh great... Rely on the inaccurate thermal diode from the socket. I never said it was impossible to do 4.2GHz... go re-read what I said. I said 4.0-4.2GHz is absolutely doable on air but beyond that typically is not unless you receive a golden chip.

You specifically said 4.5GHz+ was doable, which it isn't. Not to mention you listed an unlocked CPU which has no accurate thermal diodes when you SPECIFICALLY SAID A 955.

Thus, being that the screenshot you linked shows a Phenom II X2 555 unlocked into an X4 doing that overclock I would chock it up to being a golden chip.

Ok, here is a 955 on air. The temperature was said to be "reasonable".

I can provide so many more and these are all recent and on air. Common temperature is 52+

Look, I'm not claiming anything, but enough people have tested it. I'm talking specifically for the new 3 letter batches. Most CPUs bought before 2011 aren't from these.
I'm not going to post any more screenshots since you're obviously don't like it. Believe in whatever you want.

What 3 letter batches? The batch #'s are 8 letters/numbers long so you obviously have NO IDEA what you're talking about then.

You don't with the DirectX 11 and High res patches unless you run 640x480. Even a single GTX 580 only runs it at 40-50 fps with 1920x1080 so unless you consider a low resolution decent or less than 10 FPS playable you're not maxing Crysis 2.

There isn't such a huge difference between those cards. Maybe only 20-25%. So if a GTX 580 can run it at ..say 45, a 6850 can run it at least 30-35.

After the year/month of manufacturing on the batch there are 3 letters instead of 4.

Not true... Crysis 2's DX11 Patch/High Res absolutely destroys mid ranged cards especially with the lack of VRAM.

See, almost 50% difference between a 580 and a 6850 at 1920x1200. AMD GPU's just don't have the optimization for Crysis 2 yet which is suppose to arrive in 11.7 or 11.7 hotfixes I'd imagine.

[haxartus]

Actually, I have a perfect idea what I'm talking about. And you haven't touched an AMD CPU in years, am I right ? You are trying to attack everything I say based on a thread on an internet forum...
You showed 4Ghz on 1.52v, I showed 4.2Ghz on 1.45V. This is the difference in the new batches. I'm quite sure that the people who have provided me with the results are more competent than 3/4 of the people here. No offense.
