The Official OC (OverClocking) Thread!

you're right about ValueSelect Corsair, it's $122 a piece here (512MB DDR400 CL2.5), still Kingmax's cheaper and i haven't found any difference between these to or some test/benchmark that would say which one's better OCd or faster.
by "help" i mean: would the cpu or ram be better (higher) OCd with this brand of memory?

 

i found Kingston HyperX 512mb for $105 at a local shop i think thats pretty good...

 

Thats a 2700 for got to add and the 3200 at about $115

 

Gotta be the simplest O/C ever,
switching 166/333 FSB to 200/400 ;-)
Instant XP3200+ and PC3200 running @ 400DDR for the first time (I used to run it synchronous @ 333DDR 2-2-2-5).
Heat not too bad; core voltage pushed just past 1.7v makes it happen, no prob.
Timings @ default/compatibility now, CL2.5,
I will be happy with that if stable!
I have installed a 60mm > 80mm adapter (little funnel) to run 80mm fan @ 4400rpm on CPU.
Moves more air than 60mm 7000rpm (much quieter too) and supposedly gets rid of 'hot spot' directly under 60mm fan centre spindle.
I'll let ya know if it melts down ripping DivX
but WTF XP2500+ chips are less than half $ XP3200+
so if it cooks I won't be suicidal...
L8R

 

Finally I make a huge improvement... as I said before, I couldn't make my CPU Athlon2000+ run any higher then @ 171 MHz... well, I tried to bypass range between 172-189 MHz and started up there @ 190 MHz and voila - it works. Now, I'm running 214 MHz x 10.0 = 2140 MHz with RAM @ default setting CL3 3-3-7 @ 430 MHz. It's 100% stable, i've tested with all the benchmarks and games I have here (Sandra 2004, HotCPU Tester, Prime95, PCMark, 3DMark.. games: Sacred, NFSU). Of course, I had to raise the voltage of the CPU from 1.65 to 1.90 V and RAM (just for cause) from 2.65 to 2.75V, but it's working smooth and well. Temperature is lower then when OCd it as 166*13 (2120 MHz as well), but it's still a bit hot (some 62-63°C) - but keep in mind i've got only the standard BOX HSF and no extra fans in the case, so it's pretty cool as far as this is concerned )
Keep up the good work all of ya OCers, I promise I will.

btw, is there any way I could post an image from CPU-Z for example? (as a proof)

 

About Ati Radeon X800Pro Overclocking......

Ok overclocking my gpu is simple cause I can monitor its temp at all times and figure out what the best clock speed would be either when using a Vga Silencer or watercooling, but when it comes to the memory I'm clueless.
Ok so I bought some copper ramsinks the other day and was wondering what a good overclock would be with these installed on the memory. Anyone know???

 

I just upgraded my system (stats in my signature, similar to Praetor's). In purchasing an XP3000+ and PC3200 memory, have I maxed out my OC potential? Because I can't seem to get any performance improvement thru OC'ing (as measured by 3DMark2001).

I leave my memory freq at 100% (otherwise it won't reboot), and fiddle with the CPU multiplier, but nothing seems to change (currently at 12.5). Am I doing something wrong? I noticed I can't modify the "CPU interface" in the BIOS - it just says "optimal". Could that be part of it?

 

Sup everybody!

Have read all the stuff that all you guys have already done with the OC of several processors, pretty amazing.
Now, i have a question

Got an XP2000+, suposedly is a BARTON (can this be possible, the letters on the micro are AXDA?) and now i'm OC to 1.8Ghz with FSB 150, multi not changed and voltage not changed, temps are around 35degrees. I have an MSI KT3Ultra2R running fine, with an Kingston 256Mb x 2 PC2700. The settings for my memories are 2-3-3-6 and are running pretty fine. BUT being as greedy as i am, i wonder if there is a chance that i can OC for 2.1Ghz or more, i have good cooling (Thermaltake TR2 M2) running a LOW with no temp problems. HOW CAN I GET THE 2Ghz or more?
have played with the FSB and i cant go beyond 150, the system locks or reboots, tryed the voltage (1.60, 1.625, 1.655, 1.675, 1.70) with higer FSB = no results.

However, I have tryed with combinations like FSB=157, voltage=1.625 and got the system running, but on windows, like after 10 mins of usage, the system locks. Tryed for diferent voltages for the same FSB -> no boot or more locking. Memories are at 2-3-3-6. Any ideas?

Thnks guys!

 

Hi Impera,
No I don't think you have a Barton.
The Barton core runs minimum 166(333DDR) FSB and has 512KB cache.
Your XP2000+ runs 133(266DDR) x 12.5 with 256KB cache.
If your MSI is a 333-capable mobo, then you could try your FSB @ 166(333).
166 x 12.5 = approx 2080MHz
Important: this 'OEM' O/C applies the proper dividers for AGP and PCI, so they remain 66 and 33MHz
Your memory is spec'd for 166(333) and so, your mobo would run 5:5 synchronous FSB:RAM
Set your RAM for conservative or SPD settings, and try to make your rig POST at the 166FSB.
Apply CPU core voltage as req'd.
Ensure excellent cooling; don't go nuts with the voltage.
If it won't POST within a few tenths of the OEM voltage, it ain't gonna happen...
WTF, with H2O-cooling you could really crank the voltage - just don't start a fire (or blame me) if it melts down, right? LoL ;-)
Actually, XP2500+ Bartons are cheap-cheap-cheap right now, so you could simply procure one and pop it right in! Factory-stock voltages, low heat and 512KB cache (bonus) too...
But good luck with the XP2000+
Regards

 

Thnks OGS, i shall try the FSB=166 and play with the voltages (my mobo does not let me go beyond 1.700v) lets see if it works.
Memories are right now at 2-3-3-6 with 4way interleave, tryed 2-2-2-5 but winxp got an error and reboots
Of course i'll like an h2o cooling, but no budget for that anyway, i have put several fans over the case (this is nuts, i mean, i have disarmed a processor heatsink, take off the fan and put it into the case hahaha and it works fine!) and the cooling is fine, with low rpms on the TR2-M2 the temp is max at 45 with load.
so lets try, shall post for results. THNKS!

 

OH well, tryed the wiring -> no results, tryed simply with 166 FSB -> no boot, played with the voltages -> the same. Maximum of 150 FSB and 12.5x, voltage untouched.

BUT with 158 and 157 FSB i got Windows boot, but it locks. can be something about memory settings? cant go beyond 1.700v, perhaps rising the memory voltage?

 

WOHAA, made it finally with the "single wire" trick and FSB=166, however the system locks from once a time. Shall try rising a little bit the voltage to see what happens. lets see.....

YAHOO, its stable, at least with high load, i have to try with EXTREME LOAD!!!

finally i hit the 2GHZ THNKS EVERYBODY no i am happy with this.
Shall continue with all this stuff, if i can help anyone else, i shall!!

 

OH well, since i finally hit the 2Ghz barrier, the system is quite stable, at least while running applications and stuff, can be for hrs working on that with no problems, even running the Prime95, with no problems.
HOWEVER, it seems that when i pay QUAKE 3, my system locks.
tryed several memory timings -> can only get a little more of playing time.
tryed rising a bit the mem. and processor voltage -> same thing, still locks.
Well it seems that i have to use only the FSB=150 in order to get the system to run stable WITH THE GAME.
Well, it was fun having the proc. at 2Ghz, while it lasted. ^_^

 

woz up Praetor, i need your advice on a couple of things. the first is that i want to overclock my computer, my PC is running at 1.79GHZ with what i've read thats shite for what i've got. PC specs are AMD 2200+ with retail heat sink, 512 DDR RAM PC2100, syntax SV266A mobo (VIA chipset KT266a).

the second advice i need is that i'm buyin a second PC, with a AMD 2500 barton and want to overclock it to 3200 like yours and i need to know if this cooler is enough to cool it down, Arctic Cooling Copper Silent 2l. http://www.ebuyer.com/customer/prod...=c2hvd3N1YmNhdGVnb3J5X3BhZ2U=&subcat_uid=648. also i need to know if i OC the 2500 to 3200 will i need a mobo that supports upto 3200.
thx

 

so know i need to know how to over clock me 2200
thx

also wot board u running you 2500
