My very nice (and economical) celeron D overclock

[aidanjm]

The multiplier is 18. A FSB of 211 gives ~ 3.8 ghz.

I was only aiming for 3.6 ghz, so I just bought some pc3200 memory. It booted and ran stably at 3.6 ghz (fsb at 200, multiplier at 18)) so I continued raising the FSB. It crashes between 3.8 and 3.9 ghz. I wonder if that is down to the memory (it's already running over spec, it is only rated for a FSB of 200) or if it is the chip that causes the crash. If I had bought some e.g., PC4000, would the chip go up to 4 ghz or higher, I wonder?

I have slightly undervolted the chip, it is at 1.3 volts. The memory is at standard volts.

At idle, it is sitting at 34-35 celsius (according to Motherboard Monitor, with CpuIdle running).

All in all, I am very pleased, it was a very cheap chip for email/ web/ MP3/ divx viewing and I got a 1.4 Ghz over-clock.


Edit: a Sandra arithmetic benchmark at 3.91 ghz.

Nice Kick in a mem divider and/or relax the timings and go check out higher frequency space for the CPU

Undervolted? Is this some crazy celeron overclocking tip? I'd say run it at least at stock voltage. Are you prime95/superpi stable?

Nice OC BTW

try stock volts on vcore, 2.8vdimm, and see where you go.

 

[sangyup81]

not bad for a $75 processor

but you didn't say you were prime 95 stable so I assume you are not?

 

[Jayczar]

more bench tests!

 

[imported_Kensai]

That's a nice overclock. I want to see the scores though.

I had it undervolted to keep it a bit cooler. Lowever vcore didn't seem to adversely affect stability, so why not?

No, I haven't tested with prime95, but let's just say I have, OK?

what bench tests, what scores?

For some reason my motherboard only offers 2 and 2.5 memory multipliers. It's a gigabyte 8ipe100 pro 2.

 

[Sentinel]

bench pics?

 

[imported_Kensai]

Maybe something like PCmark and 3DMark or something?

The best Overclocking Celeron is the CELEROn D 330J on non J.
The 330J is for 775 Platform Motherboards and the 330 non J is for mPGA Motherboards.
The celeron 330J is on 2.66 Ghz with A voltage of 1.33 Volts
to oveclock it to 4GHz you will need:

A motherboard like Abit AG8, DDR400 ram...or even better DDR 466 Ram and a cooler from Thermaltake like the Thermaltake Big Typhoon or Thermaltake Sonic Tower
You will need to overvoltage the Cpu at 1.47 Volts and set a DRAM ratio of Sugessted 1.1
if that doesnt work try 5.4
A litle overvotlege of the ram would hurt.....try to volt it at 2.6 or at your own risk 2.7
THATS IT

I take no responsbility if anything happens to any SYstem.... iJust give Advice.....i my self hace a Celeron and Will make it a 4GHZ celeron in a Week or So

 

[Elcs]

Nice. A Super Overclocking chip.

Its a pity the Celerons arent the greatest chips performance-wise although if your benchmarks prove otherwise, it'll be a pleasant change

I would think getting a 2.4 ghz chip to 3.8, 1400mhz overclock is a better overclock then getting a 2.66 ghz chip to 4 ghz, 1334 mhz overclock.

 

[Duvie]

Run some damn test already!!! Lets see what a neutered chip ike the celeries do when oc'd this high....My guess is it would still get beat by a 3ghz prescott and a 3100+ sempron with a modest OC.....

 

[mwmorph]

celyl Ds are pretty decent. i think it would be between a P4 3.6 and a P4 3.4 in performance.

 

[Duvie]

Show me some benches though....I have never seen a celery be that close to the top line cpus....

 

[mwmorph]

in most apps, the celery 2.8D is faster than the 2.4northwood(200fsb,DDR ram) and slower than the 2.6 northwood(200fsb, DDR ram). now in lame it is same speed as 2.8E presshot. now in Winrar, it's faster than the Northwoods 3.06 through 2.4 running on 133fsb and RD1066ram but slower than the 2.4northwood running on 200fsb and DDR ram. In Sissuck the 2.8E presshot out svcores it 8100 to 7700 , but it still manages to outdo the northwoods running 133fsb up to 2.8ghz(Dhrystone). In whetstone, it is about equal to 2.53GHZ northwood 133mhz fsb RDram/Barton AMDxp 3200+/2.6ghz northwood 200mhzfsb/ddr ram. the results are really weird. in some tests, it does well and in some tests(like multimedia) it gets raped.

I believe XBit ran a piece on a Celery D @ 3.8. IIRC the results were very mixed, with their conclusions favoring other solutions. In any case, nice OC. Most of the fun in OCing is the journey, not the end result.

you can see what is neutered still is the fsb and the L1 cache is tiny....

Looks like gaming is the area my conclusion is closer to.... at 3.55ghz it is slower then a sempron 3100+ at stock 1.8ghz and loses to a 2.8E prescott


http://www.xbitlabs.com/articles/cpu/display/sempron-2600_10.html

again in gaming it wont be as comparable as stated above

http://www.xbitlabs.com/articles/cpu/display/sempron-2600_11.html

however in apps that dont seem to care as much about cache size the Celery D looks very comparable to P4e's as stated by mwmorph....in video and audio encoding a STABLE 3.8ghz wouldn't be matched by a sempron oc'd to any reasponable amount that I ever seen...ONe thing though is that it gets biatch slapped in 3dsmax....

All in all a great oc made a lackluster chip more worth it....

 

[Lonyo]

Especially for a non-gaming system^^

 

[Haxorious]

Well.... what can i say...... you can always show your friend that has an 800 MHZ cpu your Super Beastie that has 4GHZ of CPU....... wouldnt that be NICE
i mean....helll you could make the dude wanna die
Cellys are pretty good but when it comes to beating a Pentium 640 they tottaly loose it its like MY cpu at 3.0GHZ had exactly the half performance of my friends 3.2 PENTIUM

 

[Acanthus]

This makes me feel better about my 3.0 @ 3.6 I thought for sure the Celeron @ 3.8 was gonna take me, it seems they lose a lot more than their traditional 10% for the cache neutering on the Celeron-D, they look to be a good 20-25% behind in gaming.

Duvie..... is the venus 12 cooler too Noisy... i am thinking of bying it
My motherboard doesnt have options for Overvoltaging so i am planning on buying An asus p5gd1 pro

mY friend has a pentium 640..... and he gets Double the points in every benchmark....
Our systems are the same... except of the CPU
