im not an overclocker, but wen i get my new AMD rig id like to start learning. :)

ive read around the forums a lot over the last few days, and came across ppl saying that if you unlock a +1 multiplyer or sumthing on the 955 you get a 965.

ive kinda picked up that if for example, i wanted to try and take either of these 2 cpus to 4.0Ghz the less voltage and heat i do it in the better.

im thinking even tho it seems easy to turn a 955 into a 965 would the 965 perform better wen OC to 4.0 (less voltage/heat) or is it only a matter of an extra volt/degree which doesnt really make any difference really.

am i thinking on the right tracks?lol

Jake:)

sorry i should have posted this in the Overclocking section. If an admin could move it.

It won't get to 4GHz.

Look at the pre-overclocked bundles. I think they have the hexcores at 4 but the 955/965 will top out at 3.8. I suggested the 955 as you save £20 odd over the 965 then adjust the multiplier to make it the same as a 965.

AMD have admitted the two chips are basically the same only difference is the 965 has a slightly lower voltage range
 
There's a very good chance of the C3 stepping chips getting to 4ghz actually. The C2 965 topped out at 3.8ghz usually.

Have a read of this, contains everything you need to know. :)

Where is your source for this information? Actually the 955s are identical to the 965s apart from they didn't reach the same standards during the testing and binning process, so they are sold with the multiplier one notch lower to ensure stability. If it's overclocking potential you're wanting the 95w 1055t would be my choice at the moment. One of the members on here has got his to 4.25ghz stable and 4.4ghz benching. My C2 965 would only go from 3.4ghz to 3.8ghz, an increase of roughly 12%, so I packed it in and run it at stock now.

Don't get me wrong muel....i'd love to be proved wrong but ive not heard of the 955/965 getting to 4ghz. I know the 550s have managed it.

Jake has yet to order his parts (seen his thread). I suggested he looked at the preoverclocked bundles so he coould get an idea of whats possible with what kit. Nothing stopping him buying the same parts and trying the overclock himself.

Trouble with overclocking jake is that two people can have the same cpu but they arent exactly identical. AMD rate the chip for 3.2ghz lets say that is guaranteed you may be able to push it further but some can go further than others.

There is also a feature called core unlocking. I have a 555 it's a dual core, some are X4s for example with faulty cores so AMD disable them and make good of the remaining cores. I was lucky in that my cores (touch wood) are all good so its a rebadged x4 to meet demand. I havent oc'd it as i didnt wanna push my luck ;p
 
Look in the overclocking thread! Plenty have made 4.0ghz. I even managed it on my C2 stepping. Very unstable, but plenty have managed to get it stable on the C3 stepping.

Here's my SuperPi run at 4.0ghz.

Honestly though if you're planning on overclocking, I'd seriously considor the 1055t. Even the 125w ones will usually go over 3.7ghz, and have 6 cores.

Not where i originally read it but there you go muel

p.s I consider an overclock to be official if its stable and useable, shame yours couldn't cope with the 4ghz. I was worried that as a novice jake would buy the chip and try someone elses settings and burn out the chip. We are aware that the results are user specific based on cpu and the components used....novices might not appreciate that.

I'm no OC guru and maybe it was a lil silly saying it wont get to 4ghz but i think 3.8 was a good expected stable OC for most 955s.

I know your biding your time jake so keep asking questions and reading around. See what people use hardware wise and software too to test. Remember the talk of the crosshair board on your other thread? Wayne considered it a waste of money but maybe some overclockers really value the extra features it offers but then maybe there is a more common mobo used you could consider.
 
955/965 can get to 4GHz
Just gotta hope that you get a good chip. The newer 125w ones are more likely to get 4GHz. I would try mine out but my crappy OCZ ram is RMA'd.

MOOGLEYS has got his to 4GHz and still doesnt go over 41 degrees (or summit like tht) and thats air cooled
 
yeah ur right, picking a solid OCable board if im going to go that route is a no brainer. wen i do a bit of basic overclocking, ill get hungry and want more and probably want a new board. so ill be kind of futureproofing myself :)

thanks honosuseri & muel
 
Personally I would recommend one of these and a 95w 1055t.

I'd also get some super low latency 1600mhz RAM, I heard that they behave better with 1333mhz RAM, so you could tighten up the timings even further. :)

jakesnake,

My advice to you is use your PC at stock for a few weeks before you even consider overclocking . . . it's gonna be stupidly fast out the box and not hold you back in anything you do! :)

While you are using it you can slowly but surely read up on overclocking theory and take small steps while you build up your technical knowledge and confidence . . . if you rush into the crazy world of clocking you are only gonna get in a twizzle and get frustrated! :D

Are you buying a new computer to gain a new tool that allows you to do cool things like playing cutting-edge games etc or are you buying a new computer to become an overclocking champion and compete with other overclockers worldwide?

I've been overclocking for 15 years and I've reached the conclusion its basically much-ado-about-nothing . . .it's not really anymore exciting than a hobby like trainspotting or birdwatching . . . there is nothing wrong in tweaking/adjusting/enhancing your computers performance to get the best out of it but never forgot its what you do with the final product that is the exciting part . . . not the computer itself! . . .

if you don't keep a check on yourself and surround yourself with "crazy" overclockers you will be spending money like its going out of fashion for no particular reason! :cool:

honosuseri,

give the poor guy a break will you! :D

Your pimping the £170 Asus Crosshair IV Formula so badly :confused: . . . jakesnake has absolutely no need for a motherboard like that so why are you so intent on "suggesting" its a good use of his money? . . . an unlocking button, optional Tri-Fire etc is really not a useful thing for a novice who doesn't own a money tree ;)

if you think its such a great board then buy one for yourself but take it from me you will regret it as soon as the new AMD® tech is released in a few months . . . that board is for rich tri-fire playboys, novices with e-slongs and worldclass benchmarkers! . . .

jakesnake is none of these, he is a cool guy looking for some honest down to earth advice on how to make the best system from a finite budget . . . respect that fact please! :cool:
 
Seriously wayne quote the whole sentence not pick and choose what i say to prove a point! Everytime i say crosshair its like a red rag to a bull to you ;p

There are two important factors for jake to consider. The mobo and the psu, these make the base of a good system. I mentioned the crosshair in his previous thread as I can buy it for the same price of the intel mobo he spec'd. So it was a like for like swap and he saved money on the cpu. I'm not pimping it!

I mentioned your name but i wasnt attacking your point of view. What i said was if he wanted to overclock then look at the options available and what people use to get good results. You thought the extra options (mostly overclocker related) on the crosshair were a waste of money and yes you had a valid point for a gaming rig but now he's talking about OC'ing. I told jake to see what people use and if those features become valid for overclocking and (NOTE) "A MORE COMMON MOBO USED YOU COULD CONSIDER".

I'm not trying to pull him into the overclocking scene or sell more crosshair mobos. Suggesting to overclock a 955 to make it a 965 doesnt really count as "bigging up" overclocking. You spec'd him a great gaming rig for a great price but if he fancies overclocking that's his call and he might want to make some small changes to what you suggested.

p.s for the record i totally agree with the post you made before training your crosshairs (no pun intended) on me ;p oh and funny that muel can link to a £150+ mobo and you dont say dick about it!

crosshair makes it easy - if you want the features and have the cash then go for that.

4ghz is achievable on any other 8 series chipset board. within reason,

it depends entirely on the quality of your cpu.

as has been mentioned, 3.8 is a very achievable goal with some really impressive HT+NB speeds that can be obtained.

i have had a lot of 965s hit 4ghz but only a few 955s

it depends on how quickly you pick it up.

search the internet specifically for phenom II overclocking guides.
Xs have a very active AMD forum which contains some interesting stickies on how to overclock the whole cpu and not just the cpu bus/multi.

BE 550 is an 955 with lowered half multi and locked cores, c2 stepping.
BE 555 is an 965 with 2 cores disabled and lowered multi, new c3 stepping.

Most of 965s and 555s will do 4ghz but they usually require high volts for that and some good cooling and therefore it's not worth it, rather run them at around 3.8 - 3.85mark at a lot lower volts, temps and increase HT/NB and tweak ram speeds instead.

The reason that ocUK is shipping their overclocked bundles at 3.8 is because they don't use the best cooling and most users will use those in cheap cases with poor cooling/airflow and therefore higher clocks might be unstable.

Both 965 and 955 should do 3.8 at stock or nearly stock volts, anything higher requires good cooling and usually is not worth it but that also depends on the chip you get.

Highlighted in red are your opinions Wayne, not fact, so please stop writing as if they are. You don't know this guy, you don't know what he'll be wanting to do in the future, you don't know his budget, you don't know his intentions for the system in the future, you don't know what he wants to use it for now.

What we do know, factually, (and that is a fact by the way, because he said it), is that he's never overclocked before, and wants to start. With that in mind, surely it'd be easier for him to start overclocking on the multi and leave the fsb alone? Also, if he can afford a £150+ motherboard, why shouldn't he buy one? This is a forum, we're all just offering our opinions. I've posted mine already.

Probably because I recommended teaming it with a 95w 1055t instead of the Crosshair + 1090T "PPPOOOOWWWWEEERRRRR" option. :p
 
Thought you weren't getting on with the Crosshair a while back? I think you were considoring getting shot of it and getting a UD5/UD7?
