Official Overclocking Thread- ALL questions go HERE

[Asus]

Haha
Don't feel bad if you end up jumping into the 9800 Pro. It's a great card and from a GF2, it will feel like night and day.

Basicly when the memory controller has to register each part of memory then it is limited to so much before it take a performance hit. Think of an excel spreadsheet. Sheet 1 the limit and if the memory continues onto Sheet 2 then there is a performance hit.

With registered memory the memory registers itself so there is no issue. It has a couple nanoseconds higher latency but that is minor. Opteron (registered) Athlon 64 (normal)

But if you plan accordingly you can still use regular unbuffered memory and get up to 2GB of memory without this being an issue for performance.

We should get back on topic soon...

PC power and cooling makes teh best power supplies period, they are expensive for a reason. 600 watt anyone? Maximum PC makes a "dream machine" every year which features the best available hardware at presstime, it has always (actually just for like the past 3 years...or 4) used pc poower and cooling.

i have a amd 64 3000 754 socket with stock fan, is it a good idea to overclock or do i need to buy a better fan (i heard stock fan on amd 64's are good so hopefully i can)?

thanks in advanced

 

[Phisionary]

AFAIK you probably can. with the 754 it's likely a 130nm and you won't get the big gains of the 90nm version since it runs hotter. but you can certainly try (technically it voids your warrenty BTW). you may get 10-30 MHz on the fsb possibly. Make changes slowly, and make sure you're stable. OCing a system and running it unstable can lead to data corruption.

get prime95 or that pi program and some game benchmarks and stuff, and run em for several hours at full load to make sure you system is stable. temps should probably not go higher than 60C.

so increase speed slowly, try to keep you conmponent clocking as close to standard as you can (AGP, PCI bus) and you'l need to decrease your memory clock multiplier if you get much of a gain(unless your ram is awesome/better-then-you-currently-need). If you increase voltage, only do it very slightly. Probably .15 or .2 volts at the max.

If you really want to try and OC, a better fan would help you, of course. Good ones run $20 and up, plus shipping and thermal paste.

This is book-knowledge, not personal experiance with the chip, btw. Do this all at you own risk, or course. Google you CPU type and see what other people have done, maybe... Meh. :\

3.2Eghz Overclocking ?

Does A 3.2Eghz Intel P4 Can Be Overclocked By Any Means Necessary Whitout High Temperature And Any Problems ??
*Whitout Any Cooler's BTW I Mean No *Azote* Or Cooling Systems Wich Cost 1000$....*

Thx In Advance

Athlon 64 stock coolers are actually pretty good. They are about the same quality as the 20$ coolers and the thermaltake coolers don't offer much more. Not really worth it.
I have OCed mine from 2ghz to 2.3ghz on the stock heatsink with a little ArcticSilver3. I do have a good revision of the core though.

If you want to OC more or need better cooling then I'd look into getting a Thermalright or Zalman cooler which cost a little more.

Depends on what revision but you should be able to OC your Pentium 4 (Prescott) 3.2GHz CPU pretty high. It will run pretty warm although you shouldn't have too many issues if it's cooled with a nice cooper cooler (40-50$) and good airflow. Make sure your PowerSupply is good enough because it will draw more power as well. They take a bit more power than the Northwood 'C' cores.

Just be careful you are not letting it hit 70C as it will downclock automaticly and you would get much less performance. It happens to a lot of home users when they don't allow it to get enough air.

Is there any way at all I can overclock my cpu? I have the Intel D865GLC mobo, and I've been hearing now that you can't overclock them and I've gone through my whole BIOS there's nothing there to overclock the cpu, does anybody know how to get it to work or no? I have a pretty nice cooler and a fan on the case which does a good job blowing the air out, I wanted to OC it to 2.4ghz or maybe 2.5ghz, just to give it a little boost and make the recommended requirements on HL2.

 

[FieryGoose]

i want to overclock my radeon 9700, do you guys know what would be safe cause i dont want to screw it up? Right now it says my core clock and mem clock are the same at 263.25mHz, i also dont know how to exactly check my temp., and what are artifacts, these are probably simple questions im just a noob to this overclocking stuff. Some advice from the experts would be appreciated...

 

[dunx]

hmmm, am i screwed for overclocking or am i missing something very simple
cant seem to find the 'user defined' setting part
Main options
Advanced options



compaq presario
mobo(motherboard?) (micro-star)MS-6390 [i think this is what it is or is mainboard different from motherboard]
amd athlon xp2400 running at 2.0ghz
win xp
radeon 9200
512 ram etc.

sorry if im a tad newbish but new to this stuff, it woudl be great if i could get some more power outa this thing

 

[Asus]

I looked up that board and the bios looks quite different from the pictures you showed. Maybe compaq changed the bios to a more limited version.

[dunx]

thanks asus
does that mean i cant do anything to up my computer a bit?
oh and i found that the codename is a Thoroughbred, is that anydifferent from a barton?

you can use ati tool to over clock it...but just use the find max core and memory...and to be safe lower it like 5mhz in each...as for artifacts they are like white dots that look like snow, or they can be like pink and purple checkorboard looking thingies...if you artifact lower the clocks until its stable

chances are that you cant since its not accesible in your bios..same thing happened to me..mine were locked. by any chance do you have a compaq, hp, dell ect? If so you probably cant

 

[bosox188]

Well it was originally a Dell, but seeing as I got a new motherboard, case/psu, video card, hard drive, and more ram I don't think of it as a Dell anymore, plus I'm running XP Pro and not the OEM Dell Windows XP. The processor is pretty much the only Dell part in there, and I'm guessing that'll be locked so forget that.

 

[firemachine69]

There's no such thing as a "OEM locked" processor.

All P4s are locked (on the multi). FSB is determined by the mobo. Intel tried to lock it, but it was overcame within 2 days of being released on the market. Good job Intel. Sure stopped the OCing.

Dunx: If that's a brand name, there *is* the possibility a simple BIOS flash might "fix" it. But that's probably a bit further then you should delve into right now.

 

[dunx]

ok, i can look into that as ill do whatever i can right now to upgrade :E
just show me the way :cheers:

 

[Shamrock]

I am currently in the process of overclocking my 9800 PRO. I have 4 fans in my computer and my card has stock cooling. I have 3 80 mm intakes and 1 120 mm exhaust. Now my question is, how high do you think I could overclock it without buying any special cooling aperture?

 

[bosox188]

Well all that cooling on the case will help, but what helps the most is to put a VGA Silencer on it. I think you'll be able to do a decent OC, get ATiTool that's the best one because it tests to see what you maximum stable OC is.

 

[Shamrock]

I did use ATITool. It is at the moment overclocked FROM 378/338 to 434/373 with stock cooling on the card and those 4 extra fans. I know I could easily overclock it to higher, but I do not want to buy a cooling device for it just yet. In a couple of months, I will purchase some silencer.

 

[The Terminator]

my cpu wont OC, at all. I hate it. I have an A64 3000+ NewCastle and anytime I OC it like 50 more MHz it wont boot fully. It starts loading windows and freezes. Then I have to reboot and hope it starts up, and jump into my bios if it lets me and change it back before I kill it or something. It this cause of my RAM, maybe I should up my ram voltage?

Can any help me here?

Ive tried putting my multiplier 1 down to 9 and increasing the FSB 5 mhz at a time, once it gets to 215, it stopped detecting my raid array; my harddrives, and wouldnt even start to boot. Anything I can do here?

 

[MiccyNarc]

I've got my 1.8 Ghz Athlon 2800+ running at 2.2 Ghz right now, I'm pretty happy with it. Normal temp around 40 degrees C.

I'm getting a Scythe SCSM-1000 Heatsink/Fan, to replace my Artic Cooling Silencer 64, so hopefully I can get it a little faster.

in thbis case you might have to up your voltages...

 

[furiousV]

on some overclocking guides, i read that the core clock speed is
[multiplier] X [FSB] = Clock speed

and i know my multiplier is 14 or something, but that leaves my FSB at 200MHz :s
my processor is P4 2.8 Prescott 1mb cache 800MHz FSB

whats different? and whats the 'external clock'?

always seeking to extend my knowledge

 

[LostBok]

as far as I understand it the core / cpu / external clock speeds are all the same thing.

the main types of clock speed are:

Motherboard: Memory
Motherboard: FSB
Motherboard: CPU
Graphics card: CPU/GPU
Graphics card: memory

 

[LostBok]

some motherboards will let you OC the FSB separately to the memory...

a lot of OEM (Dell / HP / IBM) BIOS's will not let you overclock anything.

 

[LostBok]

Mine OC's to 3200+ speed, but needs more voltage to be 100% stable and I like to leave mine on for weeks at a time, so I'd prefer to go for the cooler, longer lasting 3000+ speed.

 

[FieryGoose]

I'm getting fustrated trying to overclock my Radeon 9700, it keeps on saying that it's not responding to the drivers and it needs to restore orriginal setting's, and a few times after it said that the resulution got giant, like 400 x 600 and the color looked all messed up. All this happened just because on ATI Tool i asked it to find max. core clock. Once it restarts everything is fine, but i would really like to overclock it.

Any answers or things that i should know? (I have stock cooling and a side fan on my case that blows air directly on my graphics card pretty good).

Thanks,
:cheers:

 

[furiousV]

what is the max temperature (oC) that a P4 2.8 Prescott can take? stock cooling being used. can that be use to o/c to any other factory speeds like 3.2?

 

[cschaef13]

you could o/c it but you would have to test for stabability with a program like prime 95 and run it for like 12 hours

 

[cschaef13]

and remember to set your memory to 5:4 or you will have some ****ed up memory

 

[cschaef13]

quick question, do all of you lower your memory to 5:4 when o/c ing?

 

[Maxi]

Erm... Cschaef13, you can edit your posts.

 

[bryanf445]

any guides to ocing a pentium 4 "A"?? i know that the "C" guides are pretty much the same, but it would be easier since my cpu is a norhtwood core, and one more question, if i have pc3200 what would be the fsb of the system and the frquency of the ram if i want my comp to go to 2.7 ghz. what i mean is what would be the divider ect.

 

[Muhahahaha]

My new rig will be up and running soon, and I'm thinking of OCing the hell out of it (or at least messing around with it anyways). I don't have any thermal gel, and I was thinking of getting this: http://www.newegg.com/app/ViewProductDesc.asp?description=35-100-007&depa=0. What do you guys think? Also, I'm thinking of getting a PSU fan and maybe a GPU fan. Specs below.

 

[l337x3r1cx]

just a question... but is an idle temp of 29* celsius good for a AMD 64 3500+ OCed to 2575 mhz running on 1.6v?

 

[Muhahahaha]

Seems like it. I don't know much about AMDs though.

 

[bryanf445]

just a question... but is an idle temp of 29* celsius good for a AMD 64 3500+ OCed to 2575 mhz running on 1.6v?

yea seems pretty good, i think they can get all the way to like 50c before things get bad

 

[l337x3r1cx]

so is it ok to run at 1.7 volts if the temp is still like 33?
heres my CPU-Z http://photobucket.com/albums/v103/m4guy624/?action=view&current=2600biatch.jpg

 

[baron insig]

anything over 60 is bad anything over 85 and your conductive glue starts to melt

aka u bake ur chip

but it is hard to hit 85 but as a tip lower the better

 

[Adidajs]

ok, this isn't really an overclocking question, but about underclocking. I recently got a xfx 6800gt at 350/1000 and it seemed to overclock to 390/1000. In Coolbits I can set the 3d performance and the 2d performance. What would you guys say if my 3d performance was 390/1000 and i underclocked my 2d to 300/900 to cool it down after gaming? Would there be a problem with my card jumping up drastically in performance between 3d and 2d? Do any of you guys have a difference between 2d and 3d? if so, how much?
