hi there..
i need some help in OC-ing my PD 820. i cant get it to be stable at 3GHz.the best i can get is 2.98GHz with 1.3V..any suggestions for 3GHz?

are you on water cooling or what? better use high grade thermal paste coupled with volcano class hsf.

is it wrong place to post this topic?

TS, read this thread i found, http://forums.techpowerup.com/showthread.php?t=27108
one of the posts even stated "you can get the 820 up to 3.8 even hit 4hz with good enough cooling i was running mines at 4ghz stable but it was getting to hot so i set it back down to 3.8ghz stable its all depends what your set up is and if u got enough cooling"


well, i'd say 50/50 as his question is "technical" & about "overclocking"..
so it can appear here or Overclockers United
in any case, lets help him out as best as we can, lowyat.net forumers is one whole big family..

k..thanks guys..i now play safe..at 2.87..i really hate the fact that my bro's Black can easily outdo me.. >.<
and i'm using CM Premium Thermal Grease

Whats your idle and full load temp?

load at 3.1GHz was 50+..is it too hot? idle not sure

Not too hot.. My X2 3800+ F3 @ 3.2GHz, full load 60 under AC 64 Pro ..

wow..but under load really noisy..considering an upgrade, but no cash, so have to OC..darn..

consider trying this for your next rig?

Wow

Nice aim

cash..no cash..ang pow from you guys? hehe..back to topic please.

Me this year no angpau get.. Cuz got special reason


Try get a better cooler if u want to oc higher lo..

any recommendations?

Its even 'too' hot.... Not bad.... Could it be ur temp??? Bcuz 50c+ is not very hot.... Mine @63c.... consider urs ok

hehe..now i just want a confirmation for voltage and RAM timings.can?

yes, shld move 2 o/c section.

Can..... But, move dis topic 2 OC united 1st....

argh..get it done and i will close it..tq

Grab a nice liquid cooling system lo if u got enough budget..

or esle grab thermalright ifx-14

Go here.... http://forum.lowyat.net/topic/491075 no need 2 close..... U can feel free 2 ask anything... ppl there might be able 2 help u...

-Thread Moved.

hmm... pump fsb lor, intel is pretty much simple

btw, it would be better if you listed your specifications. ( i will assume ur sig is not the one ) and xms2 sux balls

XMS2 SUX BALLS?? wtf..never knew that...ok..now i want to sell it off..haha..exactly like my sig..can help?

i mean they suck because for the almost same price, you can get much better ocing rams, like balistix, team elites, gskill etc etc

O ok, as per your sig, hmm... nforce chipset huh? :S

well for starters, go to bios, set the ram ratio to 1:1, so that its the same as the fsb. then pump the fsb, and set the memory command to 2T instead of 1T to see how far they can go

oh yeah, one more thing is that nforce chipsets are known to be nuclear generators snce nforce4 days. so... check the temps of it la

thanks..i have added a fan on it..

Added on January 26, 2008, 1:12 pmhmm..can i add a DDR2-800 RAM to my rig?

This post has been edited by ericmaxman: Jan 26 2008, 01:12 PM

Added fan Hav u done da steps as mentioned above???

N DDR2 800 can.... But it will only run @667 Might as well stick 2 ur old 1....

will do it afterwards..how to set the RAM:FSB ratio? cant see those settings

for waht you wanna add ddr2 800 rams to your system? its wasted power due to the NB bottleneck, heck even ddr2 533 will be wasted power hahahah, unless if you oc more then 266fsb ( QP for 1066)

hmm its normally called 1:1 ratio, or synchronous in the bios, it should be in the ram section

will try to locate the settings

Added on January 26, 2008, 1:32 pmhmm..there is none..but the is a linked for FSB..is it that one?

This post has been edited by ericmaxman: Jan 26 2008, 01:32 PM

but again, please be very aware that nforce chipped boards are nuclear generators. they are HOT, even at low fsb speeds of 800

i know..really regret buying it man..
btw, here is a screenshot..

is that your stock fsb or have you upped it already?

the voltage for cpu is abit high at the moment, lower it to 1.3v first

i've upped it..the voltage lower it? ok..wad about the ratio?

done..the voltage now is 1.3000V

This post has been edited by ericmaxman: Jan 26 2008, 01:43 PM

FSB speed set it to stock. QDR = 4x the actual fsb

the NEW mem speed, set it to something lower, it should be the lowest speed, which is normally 1:1,

so, the FSB i set it back to 800? the ram lowest 533? or 400?

if fsb is at 800
the ram should be 400

that is 1:1 ratio anything more then that values are not beneficial to both performance and power consumption

coz the fsb is actually quad pumped, so 800/4 = 200
ddr2 rams run at 2x the rate, so 400/2 = 200

get it now?

then to overclock raise the fsb speeds only, the ram speed will follow whatever the fsb is at

ohh..thanks..will try..voltage?

no pump fsb first, add voltage sparingly if non at all, it is to stabilize cpu or rams, or high fsb overclocks

darn..stress test hang at 3.01GHz..57 hot meh? then how come hang? voltage is at 1.3V..RAM at 400Mhz

Did u say RAM @ 1.3v??? I thought 1.8v

no, CPU core at 1.3V

Ooo... sori... got confuse

Well, i snap mine @ 1.37v... min 1.35v.... urs @ 1.3v, im not so sure.... Try increase sikit....

hurm, try adding voltage to 1.35v for cpu and rams 1.9v

and dont leave those auto overclocking options on, they tend to overvolt alot

keep an eye out for temps too, because pentium D are nuclear generators

so many times you said that..now testing whether stable or not..a bit of NFS:MW does help...

Added on January 26, 2008, 2:50 pmit keeps hanging at about 3-4 mins of the game..i've upped the voltage to 1.35V, RAM to 1.9V..wad else?overheat?i now oc to 3.01GHz only..

use orthos or occt for quick testing on stability and temp checking.

What is the NB temp? during load and what is your psu?

@eric
get WC if you intend to OC pentium D man Those darlings are like Angelina Jolies in the proc world. Nuclear Gens like Bryan said
