INSANE overclock on Celeron 325 (2.5Ghz) to 3.8Ghz

[NOBEL]

I was setting up a friends PC with a Asus P4R800-V and the Celeron 325 (2.5Ghz). The system posted fine, temps were 39-41 C, not the greatest but acceptable.
After 38 hours of memory test I felt the memory was okay, so I decided to run the Belarc diag program, and it gave me the CPU speed @ 3.8.
Wondering how the HELL I did that, I noticed that the FSB was at 800, not the 533Mhz which the Celeron's run at.
AT the time of posting this thread, I realized that you would want to see a screen of CPU-Z, but I had already given him the PC.

Anyone slightly interested in this, the CPU PROD code is as follows:

BX80546RE2533CSL7ND

BATCH NUMBER:
7414A738

Holy Hell!!

Where did he get it and when?
What cooling?

wrong thredit

 

[JeremiahTheGreat]

lucky guy.. i could only get my CeleronD to 3.2 Ghz

 

[Lyfer]

Yes the new Celeron D's do overclock pretty high but they still offer pretty poor performance compared to the mobile XP's. Do a search, there has been a thread on this a while back.

 

[StrangerGuy]

A 3.8GHz Celeron D is comparable to a 3.2GHz P4 prescott. Link

A 2.5GHz mobile barton is comparable to a A64 3200+ IIRC. Link (Not a good one, but it should you give a general idea where the 2.5GHz Barton stands)

 

[Corporate Thug]

benchies please

It's slower and more expensive than a OC mobile barton which would annihilate it. While better than the northwood celeron, it still, even widly overclcoked, represents a poor value since it loses on both price AND performance to a AthlonXP.

At 3.8 celeronD benches are here:

Why do I say a mobile barton @2.5-2.6 will whip it? Because here it is beating on a 3.2 prescott which is even a bit faster than the 3.8 celeron in the previous review.

I think an overclocked Celeron D would be great for a media encoding machine, if nothing else.

Hmmm, I had a Mobile Barton 2600+ that would barely do more than a bit over 2400. YMMV. I just ordered some Mobile Barton 2000+ 35W chips to play with. Wish me luck. :thumbsup:

I wouldn't mind having a Celeron D to play with. Maybe if I can catch a great Fry's deal with a disposable ECS 848P chipset motherboard. Hmmm, perhaps can do a pin mod to hard set it to 800MHz FSB (remove BSEL0) and then do a wire mod for voltage. Maybe get a 3.8GHz $99 mobo/CPU???

How about trying to reach 4GHz on one of these puppies? I think I'd get wood if I booted into Windows at 4GHz+. :laugh:

Well i would if I had the money buy one of those just for Sh!ts and giggles! I know it'll be utter slow but still

Sorry you had bad luck

I'd love to get a celeronD too

Here's how I'd rank the value CPU's right now for overclocking.

1. Moblie XP, $77-$95 not the fastest but still faster than celeron, but with the overclcoks these chips are seeing, insane low price and the NF2 soundstrom mobo's really have to push it to the top.

2. A64 2800+ $140, these newcastles overclock very well and with the new high HTT capable boards like the 250GB at 2.5Ghz will destroy that XP above and just about anything for that matter.

3. CeleronD $120. Good chip it seems from initial clocking results at the right price. And if you believe in intel chipset mythology it's the way to go. If you can get 3800mhz on stock HSF its a phenominal value.

4. TIE ~$170 either a A643000 or a 2.8 P4C. We all know those P4C's are better than thier prescott brothers, shorter pipe, cooler, very fast encoders and renderers.... considering they hit 3.5 all the time, you will have one of the fastest computers at almost anything from a "old" processor. Couple that with some very nice cheap intel 865PE mobos and it's a sweet bargian....The A643000+, same deal as the 2800+ only more money.

if someone shows me a 4ghz oc on a $120 processor with air cooling i'm getting one

For media encoding, and performance the CeleryD would be very tough to beat in the $120 range no doubt, but your A64@2.35ghz would still spank it for gaming. Owning both wouldn't be a bad thing though

Nah, though people have been getting better overclocks than me, I don't consider 11x200=2400 to be bad. Just "not as good." As always, YMMV, and mine sure did. The thing is that I never ran it on any super overclocker board. I ran it on a Chaintech mATX board using the wire trick, plus ran it on a Biostar board. Didn't get a chance to pop it in my Shuttle AN35N before I sold the chip and board (to separate people). In retrospect I think I did well.

Has the A64 chips really dropped down to $140? May have to look into that in the future. Only problem is that I have too many socket A/socket 478 boards that I stick to those platforms just because I don't have to get new boards.

The Celeron D can be had for around $90, IIRC. Hmmm, would be fun to get one and run it on my Asus P4P800 Deluxe with my Thermalright XP-120 and my 14.4 watt fan. :shocked:

And in a respectable 4th place the $45(!) Duron 1.6 @ 2400 EDIT: some say 2300 Plus there is the chancy hardmod to enable extra L2 cache from 64K to 256K (~ like tbred). /RollTheDice Maybe not worth the actual result, but for having fun on a budget and getting into easy hard mods... Edit: note the price of the 1.6 was raised from 43 to 47 (same as 1.8) at newegg this week.

Bought a Celeron D 325 (2.53ghz) at Fry's about a month ago for $85.
On a P4P800 ($55 newegg refurb),
3.85ghz on slk947 (1.5v @ 46C load)
4.05ghz on Hydrocool (1.6v @ 36C load, board will not boot any higher than 1.6v)
Sorry I don't have stock cooler data since it's an oem cpu.

At 4.05ghz 1:1 2.5-3-3-6:
SuperPI 1M: 45s
Sandra Sisoft
CPU Arith: 10382 MIPS // 2685/4964 MFLOPS
CPU Multi: 22636 Int // 26851 Float
Mem Band: 4982/4973

As a comparison, my 2.6c@3.2 5:4 2.5-3-2-5:
SuperPI 1M: 58s
Sandra Sisoft
CPU Arith: 9695 MIPS // 2696/5976 MFLOPS
CPU Multi: 14406 Int // 22200 Float
Mem Band: 4242/4242

Sorry my video card is over 2 years old, so any 3DMark will be unrepresentative.

Yeah... I know it's still just a lowly celery, but it's hack of a fun chip to abuse with
ps: since i'm a SETI fan, i'll tell you that at 4.05ghz, it takes 1:53 to crunch a wu.

 

[Sid59]

wow .. a Celeron D @ 4GHZ is pretty damn fast, relative.

Your numbers for the 2.6C@3.2ghz seem way off.

For $125 you can get a P4 2.4A and OC it about the same as the Celeron. I'd think that would win out in value over a 3.8 Celeron D. Even if you only get 3.2 out of the P4:
3.2 P4 Prescott > 3.8 Celeron D

Not that I really need anything other than my AXP right now, but if I were going to go Intel, it would probably be with a P4 2.4A.

Well you had to go and do it, bring up the duron.. actually the $40 Duron or a T-bred XP for around $55 nothing can touch thier price to performance ratio...So they are number 1... Problem is, even overclcoked, thier barley enough for demanding games out now so I felt obiged to leave it off the list entirly.

2.4A is crippled...but good point...maybe should have the #3 position. It's still a presshot which means same thermal related problems as it's big brothers when you crank it.. cD does'nt seems to be effected as much..

 

[carlosd]

Celeron D at 4GHz , who cares??, if the performance is still low compared to the A64 processors and overclocked mobile AXP. I can't believe you are still considering clock speeds as a factor for judging a CPU.
Mobile XP @ 2.5 faster than Celeron D at 4GHz. Ahh! and is cheaper. So GHz doesn't impress me, just show me the bechmarks. The performance is the important issue.
