Intel 65nm overclocking thread

Hello,

thank you for your Answer - very nice CELERON.

Sorry, i mean the Pentium 651 - the 661 is yet to expensive, i do not want spend so much money as a student for a simple CPU.

The 356 should be also much faster at 5 GHz as a 2048 KIB Prescott at 4,2 GHz? I think, that i should be able to clock more as a 200 MHz FSB - maybe 220 MHz for 5,5 GHz - or what?

P.S.: The Temperature should be not a Problem - i am able to drive my 90 nm NetBurst at 4,25 GHz and 1,55 Volt down to the Room-Temperature (+/- 1 °C). My big Innovatek-Set with six 120 * 120 mm Radiators is very usefully (http://www.innovatek.de) for such Overclocking-Action. My PSU or my VMOS-FETs could make 6 GHz impossible, but the Cooling never ever! It is very efficiently working and a good solution. ;)

356 @ 5ghz wins!!!

heavy air
stock clock/vcore = idle 38G ,full load 55G
5ghz @ stock vcore = idle 51G ,full load 69G

water (eheim + single rad)

System:

Celeron 356 retail
Intel D975XBX rev.304
4x512 MB Centon FatD9
7900 GTX
Vapochill Light Speed

Hi all. I am a fairly new to OC' so please forgive my ignorance, but I have a few questions.
I have just put this system together on Saturday, and I am trying to maximize the speed using Thermaltake BT and 2 fans blowing on the mobo.

1st question, in order to have an option in BIOS to "LOCK FREE" the chip, does the cpu need to feature SpeedStep tech? Would those be C1 rev chips? Reason I am asking is that I think I am pretty maxed with CPU speed using air cooling. @1.6v hitting 66-67C. Which sucks because I am just few MHZ from 1066 bus speed :(.

Another question, I have a Thermaltake 600W PSU, with 12V 8-pin plug and 24pin 2.0 plug. I use only 1 7900GT card supplied with 6-pin PCI connector, yet I noticed that 3DMK5 and 6 will just stop(driver error after pressing ESC, but system stable) halfway though the benchmark, but 3DMK1SE or '3 have no issues. Do U think I need use the easy plug as well or is it just driver issue?

Thank you, and great to see so many great OC's on these pages.

also, since I see so many peeps here using P5WD2-e Premium board, what BIOS did you find the best?

OK, i will take a 356 for > 5 GHz. :woot:

The heat is also the problem? I think with a DELTA-Fan on this little radiator you could raise it to 6 GHz, if 65 nm and your VMOS-FETs + PSU allow this.

Impressive! How high is the Voltage-on-Core? Very nice Overclocking. :banana:


P.S.: By-the-way, is the CELERON-Core a simple 2048 KIB Cedar-Mill-Core with deactivated L2-Buffer or a "real" 512 KIB Chip? It would be interesting! I ask myself, what exhaust more watts at 5,5 GHz - a 2048 KIB Cedar-Mill or a 512 KIB Cedar-Mill? Logically the 512 KIB Cedar-Mill, but is the stauts of the deactivated L2-Buffer completly free of electricity?

wel well well

finally i'm very happy of my pd 930..i've been using it 4,2 1,26 rs for weeks since couldn't do 4,35!! and yesterday tried 4,5 went fine 1 hr prime,,now running it 4,6 1,43v and after 4 hrs of prime and still going :toast:

here's the screen and prime is still going
tonight i wanna try 4,8 :banana:

CPU ：Celeron Cedarmill 356 @ 4.75Ghz 1.22v
COOLER：Scythe SF901 80mm @ 3000 rpm room temp 25C
M/B ：P5WDH 0401
MEM ：GSKILL F2-6400PHU2 2x512mhz
HDD ：Hitachi 80gb 7200 ata 100
VGA CARD ：Sapphire X1900 CF Edition
PSU: ZIPPY Type R 600w
OS ：WIN XP SP2

is there any program which shows if my cpu is throttleing..
it wont bench @ 4500mhz anymore and acts strange @ 4444mhz
cos cpu score in 3dmark 06 is 1.8k compared tu 4000mhz 2.1k...
and pc is lagging in games with my X1900XTX
when i got that card everything ran smoothly but few days it started to lag.
and that cpu score in 3dmark points to cpu throttle?:(

PcCI2iminal, P5W DH !!! Nice !! Tás sempre lá meu ;)

What about vdroop ?? Does it suffers from that even with 8 power lines ?

Presler 930 @ 4.2Ghz 1.35v

Anyone know where a cedar mill celeron can be bought in the u.s. ? I can't seem to find them anywhere, sorry for the off-topic post but I need a cheap upgrade soon.

that' too much vcore for me

i can do 4,2 at 1,26 :slap:

wow, thats great! Is that heavy gaming stable for say 6hrs? I see a lot of people need 1.48v to get 4.2 and above.

Celly 352 3,2ghz
Asus P5WD2-E Premium
2x512 PDP 667 LLK
Box cooling

its only preliminary test - only run and fast test

vcore 1,425 set on the start
vmem 1,9v :D

i dont check what is max cpu and ram - i will do this soon - probably today :D

yes game ripping dvd game rs but now i run my cpu at 4,6 1,44 :)
it's also rs at 4,7 with 1,48 but my ram can't handle anymore 4444 @394 :mad:

so check this out, I have been running my 930 at 4ghz, and had been reading about the bios and intel desktop utility reading bad temps.

so today I ran 2 instances of prime 95 again with throttle watch open looking for any signs that it could be heating up, well after about 20 minutes my desktop utiilty had an Alert that I was over my core threshhold. But according to throttle watch nothing was happening and everything was fine, so I opened up the case and touched my heatsink it was barely warm, so I decided to touch a heat pipe and it wasn't even hot.

Do you guys think that I am just getting bad readings and I have nothing to worry about, or that maybe my cooler (TTBT) isn't seated properly on the cpu and I am toasting my chip?

i agree i'm on watercooling big radiator and i reach 70°C after hours of prime/orthos and if check the temp with a sensor under my waterblock the temp is around 44 :mad:

The name of this Program is ThrottleWatch. My ThermalMonitor Ver.: 1 of my Prescott began to throttle at ~ 75 °C.

well after all the use on it the comp never crashed gaming stable for over 3 - 4 hrs, but it worries me that the temps could still be off, and maybe I just didn't have the heatsink on tight enough or didn't have good contact.

Last night I broke it down and removed what thermal paste I had on there reseated and tightened it down a little more this time it fealt like it was more solid. I haven't had a chance to boot and check temps though.

it was late :p: will post results tonight when I get home from work.

if it's still showing me high 40s idle and 50s load I am pretty sure its of by several degrees (+ - 10)

Final shots from the "zen point" of my system ( now with 2GB of Gskill 6400 HZ 0605 :banana: ) :

This CPU achieved 4905MHz with 1,49v @ full (1,35v in bios), but the dif in MHz doesn't compensate the dif in temperature ! It reached 69º ! :D

jVIDIA what temp at idle do u have at 4,8ghz with 1,46 vcore?
