Hi community, I have a amd x6 1090t, asus crosshair 4 formula board, 16 gb of ddr3 rams (crossair vengence 1600mhz), 64 gb crucial c 300 in sata 6, raid of WD green 2tb for storage and program files, ati 6850 1gb graphics, 550 watts psu ( but I also have 1000w one too to replace if needed),case is thermaltake level 10gt with 8 fans, adeuquetly cooled, custom water cooling. The problem is I cant go over 4,2 stable at 4,2 pc runs cool aroun 29 degrees even at full load around 31, 32 degrees so I am pretty confident that I should be able to achive 5.00 GHZ with my system, Since I came from intel platform I need your help with settings to achive 5.00ghz or beyond.
I sue a 10 inc radiator and a huge water fall coupled with a water resorvour, I use a big swiftek water pump. My desktop has alot of great fans and this desktop is running average 30 degrees in motherboard and 28 degrees on cpu with normal stock settings, at 4,2 ghz I throw so many tasks all at once but hick ups and highest temps were 36 on cpu and 38 on cpu. I NEED DETAILED BOIS SETTINGS TO O/C 5GHZ OR EVEN BEYOND, PLEASE, HELP..............THANK YOU,,,,,

5.0Ghz isn't possible with Phenom II unless your doing a suicide run and want the chip to die in a matter of weeks from severe over voltage. Most Phenom II chips struggle to get past 4.0Ghz, Intel chips can reach higher clocks on both air and water.

just to confurm loneninja`s statement i have the 1090t and im also on a highend liquid cooling system.
regardless of temps 4.2 is as good as it gets for the cpu in my experience now others claim higher but either they have a "golden chip" or there not fully stable (suicide run )
if i was you id be happy at 4.2 and start playing with your n/b and ht ect get the rest of your system locked in and you will be happy with the rig considering its not all about cpu speed

Hi ilkercatal

Why run the 550w psu, stick in that 1000w psu and be done with it!

4.2 GHZ is good, probably the top limit for stability on or at 1.45/1.5v

My 1055t runs at 4.2GHZ at 1.5v, on air just over 50 degrees on full load!

I have had Prime 95 run on 4.5GHZ, and booted to windows but couldnt CPUZ validate at 4.6GHZ

5ghz is not possible for everyday usage! yeah sure slap on a pot, fill it with LN2 and crank up the voltage, 1.75/1,85 and yes it probably will go well above that! for a few hours, or untill the LN2 runs out.

Having OC'ed plenty x6 chips, 4.2GHZ is a good OC if its 100%stable.. I have cherry picked my 1055t from a bunch I have tested and know its better than most 1055t processors!

Thanks for all the replies guys. My Asus turbo runner software gets my system to 4.00 ghz stable by itself ( me doing notting). But keeps my precious rams at 1333mhz , Could it be possible at 4.00 or 4.20 GHz with my rams oc/ed to maybe 1866 or 2000Mhz. I am convinced that 5.00 GHZ is not realistic at this point ( I dont want to go to intel for now, maybe when X58 is replaced with the next thing and I see some great stuff)
But I am not thinking about any upgrade, since I can play All my games at high settings such as Crysis 2 etc.
I would love to push my rig to its limits to see what it can do, of course I have to mention that it needs to be stable 24/7.
DOES ANYONE HAS SETTINGS FOR WHAT I AM TRYING TO ACHIVE?

Fsb 115
ht link 2.4
ram speed 800mhz /1600 should put you around 1726 with the 115 on the fsb
Turbo = OFF
Cpu Voltage Start at 1.4 and push to around 1.5 find the lowest voltage that will prime for more than 4 tests
Then bump it up a few points for safety
run the multyplyer at 3.8ghz and with 115 on the fsb you should end up around

1.45v Cpu core
4.08 ghz Cpu
1726 ram
you might have to up the nb voltage to around 1.3v same with the HT voltage ram should be around 1.65-1.69v at a guess depends on brand make ect

just a heads up i had 2 cores die on my 1090t my temps are 29 idle and 50 max so its has nothing to do with my temps AMD had me run many test for them on my cpu and the end result is the overclocked ram burnt out the ram controller in the processor
quote from AMD.
" Ideally, we recommend to test with native DDR3-1333 (calibrated
> at DDR3-1333 and not downclocked) to confirm if the integrated memory
> controller on the processor is functional. If you see identical results with

> damaged by the overclocked memory. "

So im advising caution when using overclocked ram as you could damage the cpu as i did. my ram is only 1600 and my motherboard supports 2000(oc)
Quote AMD
" NOTE: DDR3-1333 MHz is the industry standard maximum frequency for Intel and AMD."
