It's nice to see articles about AMD cpu's once again! Just goes to show that Tom's is not biased but rather report's on current trend's and competetive product's that the consumer's enjoy!

Thanks for rev!
Things i like to add are that not all CPU's are supported with AOD even having decent mobo, for example my 4850e + 780G. When overclocking NorthBrige you should really pay attention on it's temp, by simply touching it. Recently i overclocked my system by rising FSB and IGP. Looking at temps given by BIOS and some utilities everything seemed to be ok about 50c, but when touching pasivly cooled NB i couldn't hold my finger for second and heat was so great that even CPU got warmer! When i measured it with multimeter it was 85c idle! And i was wondering why on 3DMark i got blue screen... Problem was solved by adding fan in zone of NB.
Anyway, moral for those who are willing to overclock is - don't relay on temp measurements given by some utilities. Sometimes it's worth double checking or u can burn something easy. :) Good luck!

I realize that the price difference between the "black edition" and normal processors aren't that much, but I have been wondering how well the "vanilla" cpu's would oc. I've done some light searching for anyplace that's done this and haven't found anything other than people attempting to max out the BE's.
Does anyone know what a good OC on say the X3 710 would be? It's about $40 cheaper than the 720BE and if it could even hit close to 3.0 I would consider it a decent buy.

I do agree. I honestly don't think TH ever conducted a boycott of AMD. They just needed something worth saying and AMD finally gave them that. Until Phenom 2, they really had not earned recognition for a good year and a half. They didn't have bad products, but very forgettable ones.

It seems like this article was written specifically for me. I recently built a new PC and it has components used in this article and I've also never overclocked a PC before.

Specs:
ASUS M3A78-T
AMD Athlon 64 X2 7750 Kuma 2.7GHz
Patriot Extreme Performance SDRAM DDR2 800 (PC2 6400)
GeForce 7600GT 256MB
XIGMATEK HDT-S1283
Antec 500w Earthwatts power supply

My video card suits my current needs but if I upgrade to a 4870/4850, will I have any power issues if I follow this guide word for word considering my power supply is only 500w compared to the 650w the article uses?

A single 4850 and a dual core cpu around 3Ghz will be fine on your 500W PSU. If you had a cheap brand 500W PSU, I wouldn't risk it, but a 4850 should be fine for you.

The 4870 probably would be fine too but you would want to look into that before purchasing/installing the card.

yeah the photos quality very bad, btw i using ecs ECS A780GM-A Black and Atlon64 X2 6000+ why the AOD won't let me touch the OC bar?

Click on the pics to expand and they should be simple to read. ;)

Yes, thanks for mentioning this about checking by touch or probe when raising NB VID and not relying on reported mobo temps for NB temps.

Someone please answer me.
Whether there is any utility (AOD for AMD processors) which can work with intel processors?
Also, can i overclock from windows if my BIOS doesn't support overclocking?

Initial Street Pricing has spaced the X3 710 and 720 apart, but if you look the X3 720 is right now down to $150 on Newegg making it a $30 difference. I’d like to get my hands on a X3 710 myself to test on the Asus M3A78-T. It has a CPU multi locked at 13, so your OC will depend on the reference clock your mobo can hit. I question how far beyond 3.3GHz, especially if considering the X3 710 for the $625 SBM build as we couldn’t pair it with too expensive a mobo, still keeping a nice GPU, and sticking to strict $625. With the right mobo, I’d hope for 3.4GHz or beyond(similar to X4 810), but I have not used one nor even seen anyone’s results, so that’s just a guess. Of course, the flexibility of the Black Edition would be easily worth the extra $30 IMO if not confined to that strict budget.

I'll agree with Deuce that the Earthwatts 500W would have no problem for the HD 4850 upgrade. With 34A of 12V it should also handle the HD4870 just fine unless you are ridiculously loaded with drives & fans. If you look at the $750 International Challenge article you'll see I paired an OC'ed E8500 and HD 4850 with an Earthwatts 380W and had no issues at all. The last $625 SBM also used a 500W with 34A 12V paired with an HD 4870. I would have easily used the Earthwatts 500W on that system had it been cheaper at the time.
Congrats on the system; it's very nice. I like the Asus mobo, the Kuma X2 7750 Black is sweet for such a low price, your cooler choice offers great performance and is quiet, the EA500 a solid PSU I use myself. If you want to game a 4850/4870 would do wonders for the system and both are priced right(in the USA anyway).

Thank you! Right up my alley. I just bought a M3A78-T, 4870x2, and Phenom II 940 BE. Lots of people seem to be jumping on the "Dragon" bandwagon and I for one have no prior experience with AMD or ATI products. Your guide is much appreciated, it's easier than sifting through pages of (mostly) useless forum posts looking for info.

iamlouie: Im running here M3A78-T + Athlon X2 5400+BE + 4x1BG 800MHz DDR2+ GW Radeon HD4850 (GS factory overcloked to 700MHz) + 3 HDDs in RAID array + 420W Enermax PSU with no issues. So I think that you should not have any problems too. Im not overclocking yet.

Good article, 2009 marks the 10th year I have overclocked my CPU. PI 120MHz, Cyrix 300 (233MHz), Duron 750MHz, Duron 750MHz, Athlon 1.3GHz, Athlon MP 1.8GHz, E6400, Q6600.


[citation][nom]scryer_360[/nom]Here is a question unrelated to the article: Is Thomas Pabst still with Toms Hardware? Or is all this ran by something else now?[/citation]
Tom’s is been run by a CEO with directors above and upper management below him, just like Lehman Brothers. Run by founder with value and integrity is so 1990s. Now it is all about merger, selling out and huge bonuses.

I am running a Q6600 @3.0GHz and 4870 1GB. Taking into account of power supply inefficiency, my computer consumes about 250w at max load with an Antec 550w that’s 85% efficient at 50% load. (Actual draw at socket is 290~w).
