AMD Athlon X2 7750+ BE

BIGBC · 7 Oct 2009 at 15:32

Looking to overclock my mates PC.
Anyone got info on max temp/voltage for the Athlon X2 7750+ BE.

Done a bit of searching and answers range from 60-80C, 1.3-1.55V.

Looked at the AMD site but it was less than helpful.

Any input/advice would be much appreciated

Not sure on temps mine is under a Artic Freezer Pro and can do 3.2 stable and hits around 40ish in coretemp but my bios seems to report about 10c more so it could be 50c. I tend to to use it at 3Ghz volts wise mine was around 1.4 I think.

You should be able to just bump the v a little and up the multi. Not great overclocker but seems pretty quick. I can get into Windows and browse at 3.4Ghz but as soon as I fire up prime it crashs, bluescreen etc..

I managed to sell my old 6000 for £42 and pickup this for £40 so quite happy when I got it.

Let me know what you manage.

Hmm, motherboard is pretty limited. Doesnt support upping the multi and voltage options are only 1.3, 1.35, 1.4 and 1.45.
booted at 3.1GHz no issues, 3.2 gave problems. down to 3.1 and it could only do 30 mins of OCCT so I gave it 1.4V and it wouldnt even boot. Put it back down to 1.35 and 3GHz and failed after 40mins, down to 2.91GHz and stress testing now, 20 mins in.

If you run core temp it will tell you when its gettin warm core temps (by lighting the value yellow in its window) and it has a critical temperature warning set up in it too but from what i have read the max temperature at which it will operate is 73C.

always get an aftermarket cooler and only go up the voltages as they r needed to a limit of what ever your comefortable with really ( the cooler you keep it the less voltage you will need!)

Also dont worry as if you get too hot your pc will either shut itself off or it throttles the vcore to the cpu to stop it over heating or burning etc. Blowing up cpus or burning them etc is more a thing of the old days unless you manage to be very retarded lol.

Here's a handy wee review with a few pages on testing your cpu.

Im not new to overclocking.
I was asking some specific questions related to the AMD 7750+ BE CPU; read the OP.

Did you try searching for 'AMD Kuma' ?
Sounds simple tbh, and i am sure you have, but worth a mention.
Anyway, 'lucky' ppl seem to be able to get 3.2 out of them, unlucy 3ghz.
Your going to be fighting Vcore V's Temp.

1.4V Vcore and 60°c IMO, anything high temp and your dropping your OC.

well then i told u 73C as max from few places i'v read and u should know yourself max voltage is watever your heart desires stcok being 1.325 to 1.35 or so and some would say max of 1.5 and any greater water cooling if temps high at that point. check the link i had, guy gives some of his overclock details at one point after all the stock benchmarking.

73C is not the max it will operate at. It may well be the TJmax (or whatever AMD calls it) but people have run them at 80C. And the max advised voltage is not whatever my heart desires; id love to be able to put 20V through a CPU but thats just silly. This CPU defaulted to 1.38v, im not experienced with AMD and certainly not the earlier Athlon's so dont know what the generaly accepted guidelines are.
Someone elses overclock values are almost entirely useless. There are large differences required even when using CPUs from the same batch and on the same motherboard to achieve the same MHz.

Cheers for that, did try searching Kuma but it turned up pretty much the same pages.

Think the best thing to do is get a new AM2+ motherboard with better overclocking capability that will let him get a new CPU later on if he needs it.

did the board on which it defaulted to that voltage at have cpu vdda setting? which would have it larger than required when experiencing loads

Hi, I have a 7850 which really is the same chip i get a vcore temp of 21c on load and a max cpu temp of 40 - 42c depending on the game and multi tasking. Running vcore at 1.37 nb freq at 210 setting and a multiper of 14.5 in my oc tuner.(asrock board) will post cpuz and hwm if you would like.
