Overclocking a FX-55...Need help...

I am just trying to get my FX-55 to FX-57 speeds. I raised the multiplier from 13 to 14, I have it still at stock voltage which is 1.50. I was wondering is this going to harm my cpu at all since my temps are the same?

I also tried taking my ddr400 down to ddr333 and putting the FSB to 255 and my HTT was at 4x. But my benchmarks are better with my just leaving my ddr400 at 400 and just upping the multiplier to 14. Any opinions out there? Is my overclock safe to you guys?

By the way this is the Clawhammer core, my temps at full load never go past 50 celsius, it has a Thermalright XP-120 on it.

Computer specs:
Asus A8N-SLI Deluxe motherboard
FX-55 Clawhammer core
2 gigs of Corsair XMS RAM
2x74gig hard drives in Raid0
2xBFG 6800Ultra OC's
Audigy 2ZS Platinum soundcard
 
Is clawhammer the older 130nm core or the new 90nm core? I have the 130nm one myself and I cant run mine with 14x multi without instability. Wonder what I can do...
 
OK, I think I can help you out alot. I have a similiar setup, and to get "MAX" performance out of this Great Processor, what you will want to do is "UNDERCLOCK IT :D " What I did was take the stock multi of 13x, and drop it to 11x for a 2.2GHZ chip! Then raise the FSB (some call it the Htt) to the absolute highest as you can go until your PC becomes unstable. Im @ 262FSB using 11xmulti, and HTT3x for a total of 2.88GHz. You might want to consider good OCing ram, as this is all RAM dependant. My 2.88GHz will be much faster than you 2.8GHz, for the reason that the AMD chips LOVE increased FSB speeds, and this is what you have to understand. Yes, what you did was an overclock, but you will gain SO MUCH MORE by actually UNDERCLOCKING it, and raising the FSB. If you need help, let me know..... HAVE FUN.

NO!!! bump up the voltage. the clawhammer won't get anywhere without a decent voltage increase :p
have you read my a64 oc guide? :D

and newls, that's not underclocking. you may have initially, but the final clock speed is higher than stock, thus OVERCLOCK :p :eek:
 
HTTx3, never go above 1000. Also, get that memory multipler to as close to 200 or above as possible, since your ram shouldn't be too bad to get running at those speeds.
 
Newls1 has it pretty good...You do want to underclock the Multi for the cpu from the stock setting. but you will overclock the other settings giving you your full sytem performance. when overclocking you are not and dont want to just overclock the cpu by raising the multi cause the gain is minimal. we want to oc the CPU and the Memory and the Board to get the max gain of performance for the amount you wish to oc.

But here is what the issues I see.
first and foremost you are trying to Oc with 2 gigs of memory. You will find that what you gain in overclock will far exceed in gain then what you will get from the extra mem. 2 gigs of mem DO NOT like to oc well. especially with this revision of CPU mem controller. So i would highly recomend running the max of 1 gig of mem in the form of 2 x512 @ dual channel.

Next thing we need to know is what kind of cooling the CPU has?
What Power supply are you running?

As far as the settings goes this is what I would recomend but only if you have good cooling.
be sure to use SATA connections 3&4
be sure to lock down the PCI-E bus speed

CPU multi @ 11x. like Newls1 said. you will want to prolly start the CPU voltage @ 1.55vcore and will have to play with it to make your oc stable
Mem didvider @ 1:1/ 200 is the best. but even at that you can run 180. I would always try to recomend it at the 200 mark or 1:1 spot. also be sure to run @ 1T as the performance hit @ 2T is large. Mem Timings are very important for the mem i use and recomend i run @2.5-3-3-7. for the mem you have to start somewhere.. possibly 2.5-3-3-10 or 2.5-4-4-8 and get the timmings lower from that point.Mem volts @ 2.75 Vdim
HTT/LDT multi @ 3x never wanna have the HTT bus higher then 1000. its always better to be lower. the performance hit is pretty minimal. This is where the Oc performance really comes from.. is the HTT/FSB. its this that will give us a gain.HTT/FSB start @ 200 and increase this number until you hang or lock up or wont boot. then back it off untill it does or increase voltage un till it does( warnning increasing voltage with out appropriate cooling cand damage your chip) I would recomend not going past 1.6 to 1.63 on most air cooled set ups....(that would be with an XP120 and a 120mm fan)


Its a balancing act. taking from here giving there and comming up with a total oc. its fun and benificial. I also recomend that you check out the Ocing guides here on [H] forum or even on other forums.
You should be able to easilly do 2.8 ghz with this cpu. even on air.
and memory that runs right @ ddr 500.. way faster then just increasing the multi and having 2 gigs of memory.
