So I assume that means you have the 7550?

1) These chips arent known for their OC ability, you might be limited by the chip itself before the cooler, but i would imagine around 3ghz
2) Dont use software to OC, use the bios, if you are on a prebuilt machine or a board with no OC options in bios, I would suggest you buy a new mobo before trying to OC, a decent mobo for that chip wont run you more than $80 these days
3) As far as I know the "unlockable" chips are all phenom II or perhaps athlon II, the 7xxx series are all based on the Phenom architecture
4) No the "unlocked" cores are unlocked based on the motherboard they sit in, there wont be any memory in the chip that it was unlocked if you switch boards.

Pretty sure that answers all of them and pretty sure that is right, been a while since I had my 7750 so I could be mistaken somewhere, if I am, there will be someone by shortly to correct me
thanks a lot...i have asus m3n78-em mb...it has oc in bios but each time i have to increase the core frequency thats why i asked a softwre to oc....how to easily check if the oc is stable...?i have no problem running at stock but i think its bottlenecking my 5770 gpu i get only 40 fps in dirt2 maxed out setting with full AA ?? in reviews i see 50 fps maxed out in 1680*1050 resolution...how to check if cpu bottlenecks gpu...??

I think we might be at a communications crossroads, increasing the core frequency is what overclocking is...do you mean the voltage? Either way, like I said the chips arent known to OC well, especially on a stock cooler, that being said, move incrementally up, use voltage to stabilize, try to boot into windows, if you cant adjust your settings, if you can run a program like prime95 to test stability, watch your temps and hope for the best. I would say your low framerate is probably your processor yes.

ok thanks a lot.. how long should i run prime95...?to check for stability...?wat is the safety limit of temperatures for my cpu during prime...?to be stable...?will ntune support for my mb...??

'ello chaps
I need ure help, my younger brother is upgrading his rig and i suggested him for CPU to buy 7750BE, but there is a problem.
Current CPU is Athlon 3800 Single Core @ 2.4GHz, and MOBO is K9N SLi Platinum from MSI.
My question is does this motherboard support 7750BE? (with the BIOS upgrade ofc)
tnx in advance

I cant check it here at work but if you go to MSI's website there should be a CPU support list that will tell you all you need to know

Dude relax...I have got a kid and a job, I wont leave you hanging for too long but just the same cant hang out here all day.

Run Prime as long as you can, there are many different schools of thought on it though, me personally if it can pass a couple hours I am fine, other people will run it for 24-48hrs straight. As far as temps on that chip I would get worried around 55°c. I have no idea what ntune is or does

Hmmm, I still strongly recommend against using software to OC, that being said, good luck, I hope yours OC's better than mine did. Thanks
