1090T overclock in turbo mode???

I'm not the Thuban expert around here but I did have a few hours to play with one. I think your gaming would function at a higher level with Turbo disabled - this will negate any potential drawback from 'core-hopping'.

I believe your question revolves around whether you will be using the clock or the CPU multiplier for your overclock. AMD turbo works by manipulating the multiplier. With the stock 1090T, the turbo will increase the CPU multiplier from x16 to as much as x18.

If you raise the stock multiplier from x16 to x19, it is my understanding that the AMD turbo will bump to x21.

If you OC with the clock at stock, the processor will simply bump the x16 multiplier to x18 times the frequency.

For your overall benefit it may be to your advantage to purchase a 1055T, and invest in a nice motherboard. With turbo disabled you should be able to run 14x270MHz on all cores to achieve your desired clocks; and with good power management (either C&Q, K10Stat or PhenomTweaker) drop back the multi at low system demand.

Here is a look at some of my fun ...



You might be able to game with that  

All 6 cores stable, at 4.2 GHz?! Niiiice....

It was all AMD & Asus   I was just along for the ride.

I didn't test at load more than 10 minutes because temps got to 65c (on an old Opty cooler) and I didn't want to take any chances on screwing something up.

dude you didnt???? XD 4,2 ghz? can it go to 4,0 ghz and be stable?? please say yes xD am well if the 1055t goes all the way 4,0+ is the 1090t going any further? ok im going to turn off the turbo mode, i did thought about that, hey tell me waht must i look when buying a motherboard, i just allways look if it has crossfirex enabled, I just know for that info, nothing more, could you tell me?

and oh yeah i want 1090t because it has unlocked multiplayer...in fact, did you raise the FSB or what?

1.5 vCore is WAY to high

Yup. You need to do a little homework on the motherboard and what options are available to you in the BIOS for the x6.

Once again, I'm not the **x6 Guru** but the most important option (to me) would be the ability to disable turbo. The ability to fine-tune the Vcore is also very important. The issue you are going to find is that current motherboards were not really designed, nor are they optimized, to take full advantage of the x6s. See below for some more comments on the issues of tweaking the x6.

As far as your gaming is concerned, you will actually get a lot more mileage out of something like the Asus M4A78T-E // Phenom 955BE combo for $220 after rebate (if you are in the USA). That's a new HD6850, right there, with the $$ you saved   (or a retail version of W7 that you can move to a new mobo)



I'm an over-clocking/under-volting kinda guy. If I could have found a way to cut the Vcore in any fashion I would have done it -- LOL -- IIRC my 'increments' were 'only' +.1v.

Otherwise, CPUz (and HWMonitor) voltage readings were off with the motherboard. Readings were much better on PC Probe, but that didn't account for some of the other craziness I encountered.

There were voltage fluctuations and a clock 'bounce' until I updated the BIOS. The update allowed me to disable Turbo which helped smooth over those issues -- only problem was the Vcore adjustment was somewhat borked with Turbo disabled and I had to leave it on Auto.

For the price/performance I think the x6s are an engineering marvel (especially for video transcoding). I hope they are not 'abandoned' with the move to BD, and that AM3+ further refines Thuban optimization in hardware and in BIOS tweaks.

well i realy wanted the x6 because i think in latter years it will be better than x4 because it has more cores and so, and i want to have it too for productivity and record games when im gaming, that kinda thing.

oh je again, how did you OC'd it? raising FSB?

His base clock is at 300MHz vs the normal 200, so yes.

isnt that like more difficult and your realy pushing hard on your motherboard, the multiplayer does it more eficient right?

Raising the base clock affects just about every component on the board, so it can be more risky, yes. The multiplier only affects the CPU.

yeah true, i dunno i ll probalby go for the 1090t because it has unlocked multiplayer and some good price/performance mobo.
