The AMD Athlon II X4 635 is the fastest quad-core processor in the Athlon II series with its overall clock frequency of 2.9GHz. With a street price of $127 and just a 100MHz boost over its predecessor is the Athlon II X4 635 worth it? Read on to see how it performs in the benchmarks and to see how it handles being overclocked on our AMD 785G test system.

The AMD Athlon II X4 635 is the latest and greatest quad-core Athlon II processor to be released. The AMD Athlon II X4 635 comes priced at a low price of $125.99 plus shipping. Based on the Propus Die, the Athlon II X4 635 has a clock speed of 2.9GHz with a 2000MHz HT link and memory support for both DDR2 and DDR3. The chips overall clock frequency is just 100MHz faster than the AMD Athlon II X4 630, which costs $108.99 plus shipping. For an extra ~$20 you get another 100MHz speed bump, which might make some of you yawn, but at least AMD is headed in the right direction. Both the AMD Athlon II X4 630 and 635 processors are great quad-core CPUs that are ideal for someone looking for the threaded performance that only a quad-core processor can offer.

I skimmed the overclock section just now and the review looks great. However it took quite a bit of voltage to get almost 3.8Ghz. Dan, did you try overclocking with ACC enabled?

No I haven't played with ACC settings. I have found conflicting information on it. Some sites say it only affected the original Phenom series and not the new ones and some say it helps all, one thing is certain though AMD seems to be secretive about ACC. I have only had the board for a week and a half at this point I plan on becoming much more familiar with it. I will be doing more research into the ACC settings and update if I can hit a better OC or lower voltages.

All rights. Take your time and keep us updated =)

One thing's for sure. ACC can unlock cores. I recall reading somewhere that it also helps in overclocking, but just a bit.

Atleast on Phenom 1's i can tell they help alot... 1ghz in fact on my chip!

Key to PHII clocking is pure temps.

Hi I know the review was a few months old but I just built a budget rig with an Athlon II x4 and was wondering what temps you were seeing at that voltage/clock speed?

I was using the reference cooler from my AMD Phenom II 940 BE, so the temps weren't that great. I was pushing into the mid 70's at those settings. If you were to use a better cooler temps could be controlled better. Hope that helps.

Thanks I Have a 620 currently @ 3.2GHZ on Stock cooler, under full load it hits 58c Idles @ 31.

I've read to keep it under 60c So im probibly stuck at that clock until I pick up an aftermarket cooler.

i had one briefly, that seems like the common overclock/temps (i got 3.34GHz with good cooling/temps(idle 21C load 35C when i tried tweaking)) i got suicide runs up to 3.7GHz but nothing was ever stable above 3.34

I have this motherboard Gigabyte GA-770T-USB3, and i don't have stock cooling. Do you guys think i can clock to 3,7 ghz as shown in the review?

the propus cores in general have a 700-800MHz range of what you can overclock them stable, so it is a good possibility, but having a lower end board it's certainly not a guarantee
