Athlon II X2 255 Reaches 4.80 GHz

btarunr · Jan 26, 2010

Renowned overclocker Chew* set a speed record for AMD's new value dual-core processor, the Athlon II X2 255. Based on the Regor core, the X2 255 is a monolithic dual-core chip, with just two physical cores on die, and additional L2 cache, with no L3 cache. This cuts the TDP of the chip to 65W. On the bench built by Chew*, the X2 255 reached 4800.1 MHz, with a BClk of 320.01 MHz, multiplied by 15.0. The chip's natural multiplier value is 15.5x, its stock speed is 3.10 GHz. A VCore of 1.696 Volts was set.

The processor was cooled using a Mach 1 phase cooler. The bench consisted of an Athlon II X2 255, Gigabyte GA-MA785GPMT-UD2H motherboard - another mainstream component which proved its mettle, OCZ DDR3 1600 MHz Black Edition certified memory, PC Power & Cooling 1200W PSU, and ATI Radeon HD 4890 graphics. The CPU-Z validation for this feat can be found here. In the same occasion, Chew* could overclock the chip to 4050 MHz using a reference AMD CPU cooler (which comes bundled with higher-end AMD chips). More pictures at the source.

um ... yeah - may want to correct the "cascade" part - was a mach1 - lower powered SS phase (single stage)... LOL I'll have to ask why he held back on the ln2

no doubt he's held back on this review

Awesome with air........

)

heky · Jan 26, 2010

Also correct the used PSU part, the picture shows 2 1200W units. One Antec Truepower Quattro 1200W and one PC Power & Cooling 1200W. Thats a lot more than one PC Power & Cooling 750W unit.

newtekie1 · Jan 26, 2010

4GHz on air great!

@Btarunr: It was a 1200w power supply, not 750. :toast:

sapetto · Jan 26, 2010

Not validated by CPUz :confused:

whats that

wtf? congrats

Hmmm , you can clearly see that the 1200 antec OC is not hooked up to anything

It's wasn't necessary but those PSU's live on that particular bench station, other 2 stations were tied up with "other" things

Cpuz is rejecting everything right now thats AMD, even at stock, no clue.

In a word, Wow! In a few more words, too bad no benchmarks!

Nice Job chew*

My 240 hits a FSB wall at 260
Then again I've never gone above 1.48v with the crummy stock cooler that comes with it

Wow I'm surprised it didn't pop at 1.696v

A Cheese Danish · Jan 26, 2010

That is very nice! Way to go chew*!

Meh.

It's an impressive feet with just mainstream hardware.

One must ask though, was a 1200W PSU really necessary?

You must not have clicked the link. There are benches in the thread @ TR.

[H]@RD5TUFF said:
Meh.

You don't think 4.8GHz is impressive on a budget chip with an old, under-powered phase change unit designed to run on Pentium 4 Northwood's? Ok. :rolleyes:

No, definitely not, but why not?

DrunkenMafia · Jan 27, 2010

Shit he used the same MB as I have, I cant get my fsb up to 300 though.

Assimilator · Jan 27, 2010

bta, maybe edit your original post to add the info that the stock speed of the 255 chip is 3.1GHz?

Also the default multiplier of that CPU is 15.5x (15.5 * 200 = 3100), not 15... if Chew* had left it at 15.5 he would have ended up just shy of 5GHz.

Crazy OC and welcome to TPU :toast:

750w could probably power the CPU, but why not just overcompensate if it's available? Doesn't make sense to waste time possibly having to troubleshoot a bunk PSU, if you hit a frequency barrier.

Totally kills the mood when that happens... :roll:

Excellent overclock, but it needs LN2!

johnnyfiive · Jan 27, 2010

Who cares what PSU was used? That is an impressive overclock. Congrats Chew*!

breakfromyou · Jan 27, 2010

Congrats Chew*

I just picked up a 250 the other day that I could squeeze 4 GHz out of on the stock heatsink that it came with--yes, the wimpy little one. Makes me wonder what a better board would do with it. I'm using a Gigabyte MA78LM-S2H haha.

SUPERREDDEVIL · Jan 27, 2010

Awesome, go AMD Go!

Hayder_Master · Jan 31, 2010

great work "Chew*" , keep on moving , welcome to TPU

exodusprime1337 · Jan 31, 2010

hahha, i got to see some of chew*'s work firsthand, he lives not 10 minutes from me lol

Budget system benching is fun :cool:

Your wish is my command.

WOW that cheap board does 400 HTT? Impressive.

What happened to the Gigabyte board?

6GHZ is awesome. :rockout:
