Phenom II X6 1075T OverclockingUnlike the 1090T Black Edition and 965 Black Edition, the 1075T has a locked multiplier, and thus the only way to overclock it is to raise what ASUS calls the "CPU Bus Frequency". I know from my previous review of the ASUS Crosshair IV Formula motherboard that this motherboard is capable of supporting very high overclocks, so I started raising the bus frequency from its standard 200MHz pretty aggressively. I settled on 277MHz, which resulted in a stable 4.155GHz, although I did have to tweak the CPU voltage to 1.46V to make it through all the tests in this review. I always disable auto-overclocking features like Turbo Core when I overclock, since I'm trying to reach the highest frequency all cores can sustain and don't want a system suddenly crashing when the CPU tries to crank things up a few hundred MHz. For cooling, I used a CoolIT Systems ECO A.L.C. Eco-R120 CPU cooler. 
AMD may have shot themselves in the foot here, since the frequency I reached is actually slightly higher (for all cores) than the frequency reached in our AMD Phenom II 1090T Black Edition review. While there's never a guarantee how far an individual processor/motherboard combination will overclock, it's likely that most 1075T CPUs can be overclocked to be very close if not match or exceed an overclocked 1090T Black Edition. That being the case, there's little reason to pay $55 more for the 1090T Black Edition, unless the extra versatility of the unlocked multiplier is worth it to you. But it probably isn't: if you had a DDR3-1600 kit, you'd have to drop the memory speed to 1477MHz (the next step up, 1847MHz, probably isn't reachable by most DDR3-1600 kits) with a 277MHz bus, and while the 1090T's unlocked multiplier would let you maintain DDR3-1600 speeds, you won't notice any real world difference between that and 1477MHz. There is one caveat: while any 890FX motherboard should be able to hit this overclock, you probably won't do as well with previous-generation 700-series or older AM2+ motherboards. In the next section, I'll explain my conclusions about the AMD Phenom II X6 1075T processor.

i wold like to see some temperatures with 1075t OC
=> Slight typo...The mainstream desktop version of Sandy Bridge uses LGA1155. It has a different electrical layout to the current LGA1156. They aren't compatible with each other...I checked with an Engineering Sample.
I have an ASUS board in my Wish List at NewEgg that supports AMD Hex-Cores and SLI together. I had planned on using the GTX460's in it and 1090T Hex-Core once I have the cash saved.

Is Intel good? You bethcha skippy. Could they be in any rig I build? I'd enjoy that. But my last few MB/CPUs have been AMD due to the "bang for the buck" factor. Looks like my next upgrade in that category will be also. Thanks for playing Intel. We have some nice parting gifts for you. Maybe down the road....
"any clue how the mighty i7 980x is beaten by 930 in UGS Visualization mockup?"
Nope. I runs the tests, I reports the results, I speculate on the reasons when I can. This one's a mystery.
Yep, you can do a lot of transcoding on an overclocked 4-core proc; but more cores are still better. It's arguable whether the extra performance is worth the money; I suppose it would depend more on whether one was in a hobby or production environment...
I thought this was a review of the
AMD Phenom-II X6-1075T CPU HDT75TFBK6DGR CPU.
Please clarify. Thanks.

Max TDP: 125 Watts
And yes, they are efficient in the regard that they don't have the luxury of 32nm and yet keep the TDP at low 125W as stated in the article. Just remember two facts that the 1st gen Phenom 2s were rated 140W and 32nm six core Intel i7 980x/970 have an envelope of 130W. And you'll see efficiency in 125W.
you talk like a child who is ashamed of coming to school in reebok shoes when all the other kids have nike and adidas, like the choice of processor comes down to its process granularity in a trendy fashion way.
If you disagree with technical issues in the review, fine; if you just don't like my writing style, go start your own hardware review site and show us how to do it.
only with my memory i'm exceed amd

THEREFOR SOME ONE PLEASE SUGEST ME A COMPLITE SOLUTION FOR HIS SYSTEM
OBLIGED
It has answered some of my questions about the new AMD hex cores. Mostly to do with performance @ same clock speeds of these processors.
However I would still like to know, how the 1035T & 1055T shape up against the 1075T/1090T/1100T.
Are these all essentially the same processor, with different clock speeds or is there some real difference when dropping from the 1075T to the 1055T?
What would be the difference of OCing a 1055T @ 4GHZ (is this possible, with a stable system?) Vs a 1075T @ 4GHZ, if all other hardware was the same?
In fact, I may not even feel the need to overclock it (the "fast enough" thing), but it's so comforting to know that if I do, I can possibly get near-980X performance for a fraction of the price...
Another good question would be power consumption. I have read that when you overclock X6's they start gushing up power like mad, reaching up to 300 watts (yes, just the processor, not the whole PC) at around 4 GHz. That's something to consider as well, when deciding if it's worth to overclock it and to what extent.
Finally, a more straightforward question: you said similar results would probably only be possible with an 890FX mainboard. I'd love to have one, but they are prohibitively expensive here. So, I have the crippled version of it, an 890GX mainboard. Do you think the GX could yield similar results?
Thanks a lot!
While I have found that it is possible & with a stable system, the rest of my question still remains.
Also I am now wondering about the effects OCing a 1055T this high would have on the longevity of the CPU & whether this would differ for the 1075T at all? (I realize that any answer to this would be mostly speculation & also be dependent on cooling solutions etc.)
But that is not in my plans for now. I have found that even at stock speeds, it is scaringly fast! I simply don't need to overclock it, and don't think I will need it any time soon. I'm also impressed at the thermal efficiency: when idle on a not so hot day (I live in a subtropical latitude and it's summer here down South now), CPU temperature gets as low as 21°C, and I'm yet to see it go over 44°C under stress. Well, I wanted a PC to last several years, and I've got one. I'm very happy. Thanks a lot for your help!
If I understand it right, both these versions OCd to 4GHZ would draw the same power under load but at idle with power saving enabled, the 95W version should draw less power.
So I bought the ASUS M4A89GTD PRO (8+2 phase) and I reborned with it. I reached 4,0GHz in a minute with 1,425V. Max for 3D bench is 4,2-4,3GHz and the most i got with this combination on air is 4,5GHz @ 1,596V. That was very unstable but enough for one round of super pi 1M and then BSOD.
For 24/7 I am holding it at 3,8GHz @ 1,375V. I use Scythe Mugen 2 and temperatures are very good. About 45C in games, 52-53C in occt. With 4GHz 55-57C in OCCT. Scythe Mugen 2 is very very silent cooler i recommand it.
Dont use X6 processor on 4+1 phase motherboard if you want to overclock. 4+1 phase is only OK for stock 3.0GHz nothing more.
Sry for bad english.
Nice job.
