@itsakjt I got the stepping when I pulled it out today,, it's CACDC AC 1248PGT

 

[itsakjt]

I see. So the stepping code is same as mine, the date code is different. 1248PGT meaning manufactured in the 48th week of 2012. Don't know what the last 3 letters mean.
Mine is 1117FPM. 17th week of 2011. And CACDC AC.
BTW, I did 4.53 GHz today using the stock cooler and at ambient 32 degree C.

Thanks for the information @Johan45.

Nice clock especially on air!!

 

[itsakjt]

Yeah. I am trying to keep a 3000 MHz OC for the NB 24/7. But it just won't get stable. It is stable at 2800 MHz with just 1.175V. I set it to 1.1875 for a slight headroom. But even at 1.4V, it is not stable at 3 GHz.

That's too bad some do some don't, still looks like a nice CPU they gave you!

Nice, keep it going.

When I had an AM3 set, I got the worst damn 965BE (C3) ever. Only 3.7GHz stable and it ran as hot like Hell.

Well overclocking is lottery anyways.
I personally think the best chip for overclocking and getting personal happiness is the 955BE. Clocked at 3.2 GHz, 99% of the chips go to easily 3.7-3.8 GHz. That 500-600 MHz OC will make anyone happy. Also many 955s can hit 4-4.1 GHz also especially the C3 revisions. Thats a lot over stock. But consider a 980 BE where the default clock is 3.7 GHz, the average overclock is around 4-4.1 GHz. That is only a 300-400 MHz increase. But considering a 955 can do those also, that does not make the 980 anything special.

Ok so I got a little question here. If I overclock my 980 and run Cinebench for the small time it takes to run(just for setting records and all), and if the temps exceed 65C will it be damaged?

Anything can happen once you start running a CPU outside of it's factory parameters. Just the disclaimer part out of the way. My opinion is if you are getting high temps you're most likely to crash from instability before any damage is done. That doesn't mean you should go in guns blazing with 1.7v on air either. But I think you'll be OK. Like I said though there are no guarentees.

Thanks. Also I am getting a new cooler. My budget is around 2500-3500 Rupees(42-59 USD). Which should I get? I am shortlisting some: Cooler Master Hyper 212X, Deepcool Ice warrior(Both are air coolers). The prices of those two are 2600 Rs and 3100 Rs respectively. For water coolers, I have choices like the Cooler Master Seidon 120V and the Corsair CH 40(both are 3500 Rs). Which cooler should I go for. Will those water coolers be better than the air coolers? Please note the ambient temperature here in summer is around 35 degree C and in Winter is around 12-18 degree C.

 

[Johan45]

Here's a comparison page for you to have a look at , those water coolers really don't outperform the Hyper 212 by enough to justify the premium IMO but in the end tht's up to you. The CM Seidon was the better out of the bunch but still only by 1.5c over the Hyper. If you're interested in the water end save up for a 2x120 rad minimum. Here's the link http://www.frostytech.com/articleview.cfm?articleid=2744&page=4

 

[itsakjt]

Thanks for that awesome link. Wonder how I could not find it.
Anyways, I am more inclined towards the water cooler. I can often go crazy putting the radiator in ice - water. Another thing: Can pipes of non custom liquid coolers leak and cause a mess of the hardware?

 

[Johan45]

They could I guess but not as likely. They're made to go on and not come off but anything can leak.

 

[itsakjt]

Ok. Still confused.

 

[Johan45]

@itsakjt I just meant the hoses, they don't come apart easily. My guess would be to google AIO leaking or similar and see what pops up. i have one it hasn't leaked and it's nearly 2 yrs old. A TT water 2.0

I'd say no, because normal using (including gaming) rarely stresses CPU as lot as benchmarks. And I haven't never heard anyone breaking their OC'd Phenom II's. NEVER.

Thanks a lot.
My chip does 3.8 GHz at no extra voltage increase. 3.9 GHz requires some voltage increase.

 

[Ruru]

Pretty fine if with stock voltage, my crappy 965BE needed ~1.5V for even 3.7GHz!

Still, no problems with mb's (Asrock M3N78D) VRM or CPU's temp, since my cooling was fine, never hit over 63C in gaming.

Hmm you got a bad chip. Its lottery anyway. My 955BE went from 3.2 GHz to 3.7 GHz at the stock voltage. 3.8 and 3.9 required slight increases. 4.0 needed 1.45V LLC on. Max clock I reached was 4.43 GHz. I have a vantage bench at 4.2 GHz with it.

 

[Ruru]

Yeah, it was an awful chip, the worst overclocker I've ever had

If I remember correctly, it was benchmark stable with 3.9, but in long game sessions always crashed, also in stability tests. Been on Intel about 9 months and I don't miss that 965BE at all.

My 965 is a pig too, 1.51v gets me the 4.0G which was never stable on air, it would just get hot evetually and crash. Water made a difference., still the same voltage but it would at least be stable.

why does your screen shot read qpi link in the box where HT link should be

 

[itsakjt]

why does your screen shot read qpi link in the box where HT link should be

That's the thing for all AMD users. Might be a CPU-Z issue. Every AMD CPU-Z submission has QPI in place of HT.
Look at @Johan45 's 5 GHz OC here. http://valid.canardpc.com/rg4ph1

Same QPI link.

I think it has to be just a bug in CPU-z, sometimes it says HT and others it's QPI which is an Intel term but they're basically the same thing.

EDIT: I just went and checked all my AMD submissions and they all read the same. It has to be something to do with the actual validation and not the CPU_z software. If you open the SS here http://hwbot.org/submission/2562359_johan45_cpu_frequency_athlon_64_le_1640_(lima)_3733.98_mhz You'll see them side by side. The CPU-z says HT link but the validation says QPI , why I don't know but The devs might change it if it was brought to their attention. Not that it's that important.

lol, I've kept 1.546V for 3.7GHz

Like I said, worst chip for me EVER.
