Athlon II X2 Series Overclocking

[Urbklr]

Hello, I ordered my AII 240 this mourning, and it will be here tomorrow. Just wondering if anyone has one or knows what these things can do? 4GHz on air by any chance? I ordered an Xigmatek 1283 and plan on lapping it(very little) and the cpu to keep the temps down. Will have it in hand tomorrow after work, have first results by 11-12 my time(-4 Alantic).

Maintain sub 30c,and it will give you plenty of OC headroom.provided you got a decent supporting hardware like mobo,ram,psu,etc.

And do not hesitate to give enough vcore.i'd say 1.6v on air is max safe vcore.

Dont give more than 1.65v vcore on air cooling.cpu death is imminent

My PII 240 just arrived for the gf's comp, I'm in the process of moving right now though so I won't get to flog it for a few days. But I would assume like any of the other PII products out there, 3.5ghz on air should be what to aim for.

isnt that a little high for 45nm?

even 65nm shouldnt get more than about 1.6 even with water...

i say: these arent k8or k9. try to reach the clocks with low voltage... if its not enough, it will simply restart. bsod´s and freezes are mostly related to overheating of the processor, or more badly, the pwm area. keep your mosfets cooled.

I plan to not use more then 1.5-1.55v on air. I'm going water next pay. My board and PSU should take the beating and the cpu should stay cool. I'm off to work now, and there should be a box waiting here for me in 10 hours. Very excite!

Congrats Urb! You need to give me some benchmarks because I've been contemplating switching out for a Regor.

No problem man, what games/benchmarks would you like to see? If I can do it I will

 

[JrRacinFan]

Everest Mem Bench and Sciencemark 2, if you don't mind.

 

[Urbklr]

Link me for when I get off

There you go Jr. Will run the other tomorrow....today I mean. I just got the computer working half right, LAN doesn't work at all so I'm using the boards wifi lol. That OC was a first attempt, so there is much more to come.

Edit: RAM was at 1036MHz CL5-5-5-15

 

[JrRacinFan]

Thanks Urb!!!! That does help me in my decisions.

Looks like our rigs are rivals! Your 4770 would outbench the GTS in benches aimed toward newer gaming. But from the looks of things we are performing very similar.

And I'm 150MHz behind you

 

[JrRacinFan]

Too true man too true. Guess me n you will have to create a bench off thread eh? xD

 

[Urbklr]

Whats wrong with this thread?

 

[JrRacinFan]

Devoted strictly to your benches and overclocking help for others.

Would I be able to overclock higher if I moved from DDR2-800 (833MHz, 5-5-5-15-23-2T-1.8v) to DDR2-1066 RAM? My sticks are Team Elite DDR2-800s, planning to go to Team Xtreem Dark DDR2-1066s at CL5.

Not necessarily, just try bringing the voltage up to 2-2.1v and see if they go farther.

After I purchase my 965(Its sitting waiting for me) I should pickup a 245 that came in the other day just to help this thread along...then SELL IT.

 

[Urbklr]

Do it, these things are kind of fun lol. 3.8GHz right now with very little tweaking, just a voltage bump. I haven't tried it at 1.4v yet, just 1.45v.

even 65nm shouldnt get more than about 1.6 even with water...

amd 45nm handles voltage way different than amd k8/k9,even intel's 45nm.

For example:my PII X2 550 run@4ghz with 1,525-1,55v on air (thermalright ultra 120extreme,dual fans) and it never goes beyond 45c at full load (F@H smp).it idling @28-32c.

I even run it@1,6v just to see how's the temp,and it still maintains below 55c load.but do not try that lol

and yes,the mosfet area should be cooled with active cooling when Oc with >1,45v.that's why I never use prime95 or orthos for stability test.i simply use it to folding or gaming/benchmarking

I found out that the Athlon II series can really only handle up to DDR2-800/DDR3-1066 (which is in it's official specifications). I just got a pair of G.Skill Tridents that run stock at DDR2-1066 (1066MHz) @ 5-5-5-15-48-25, 1.8v, EPP. Sexy coolers, BTW.

Using the stock CPU speed of 2.8GHz, I tried forcing the RAM to run at 1066MHz instead of 800MHz (which I guess the CPU forces the BIOS to set it to), and the system will not POST at all. It's only when I overclock the CPU that I can get the RAM higher than 800MHz, but obviously it'll still be running slower than it's rated timings. I guess I may have to move on to a Phenom II which natively supports DDR2-1066.

EDIT: I just noticed that Urbklr and I may have the same G.Skills. Are you forcing them to run at 800, then clocking the CPU to compensate?

 

[ASRockIQ]

^It's best to OC the CPU first then the RAM.

 

[El_Mayo]

erm.. sidetracking question:
i'm getting one of these soon (as opposed to Phenom II 550)
are they still.. you know.. capable in gaming and how long do you think they can go before needing an upgrade?

 

[JrRacinFan]

Very capable in gaming El Mayo. Also, it depends on your multitasking, if you multitask heavily than you game you may want to look at something else.
