Bad Celeron D Overclocks?

[Alexandrus]

Can you guys with a good Celly D .4GHz OC, .6GHz or so, post the FPO/batch from the box of your CPU ?

Originally posted by: D-ManI just stuck Celeron a 2.4D in my P4P800 Deluxe @ 1.5V and it is running stable so far @ 3.8. The funny thing about this is that It will run @ 3.6 and 3.8 but not @ 3.2 or 3.4.

I have that exact same board for my Deleron 320. It seems to have a FSB "hole" from around 160-199MHz FSB, meaning it won't POST at those FSB settings. Just an irritating quirk with that board. I discovered it with a Deleron 330 that would POST at 4GHz (200FSB) but wasn't stable. So, I thought I'd lower the FSB and discovered... no POST.

Mine is a SL7JV. FPO# is 7428A336

That is a D0, thanks. I'll get one soon.

PS. My stupid keyboard is malfunctioning, sometimes keys 1 to 3 do not work, damn.

I have to take issue with this comment. Not to be a FelixDeKat fanboi, but I have to say that Celerons are quite capable CPUs. There is nothing a modern Celeron cannot do that any other modern CPU can do, only at slower speeds. Also, Celerons have often been some of the better overclocking chips on the market. This dates back to the ORIGINAL Celeron 266 using the Slot1 boards without the benefit of L2 cache.

I got one for ya.

64 bit app execution

oh, and another one

hyperthreading

those are 2 things a celeron cannot do that a modern processor can do.

 

[superkdogg]

Without the burn, it takes about 1/2 hour-without deep analysis, about 15 min. My TBred ripped/compressed @ about 2.2 MB/s on an nF2. This rig does about 5.3 or so. Sorry that all my estimates are rough-I haven't actually timed any of this. It is certainly a drastic difference, though.

 

[superkdogg]

Good points, slag. You did neglect the fact that no other CPU can do both of those tasks, and that neither is essential. I'm just playing devil's advocate, of course.

 

[superkdogg]

Does somebody with an engineering background want to evaluate section 6.1.1.2 of this link?

http://www.intel.com/design/in.../designgd/30306301.pdf

The way I read it, it says that there is a new factor in the default FSB of the Delerons, thus explaining why certain mobo's have "FSB holes" and some don't support high fsb's, etc. I may be way off base (I'm a social worker, not an Elec. Engin.) but that may explain some of the anomalies that many of us have come across. The issues may be how motherboards interpret different pins, not in the chips themselves. *Disclaimer: I'm a total newb on this front, so be nice, OK?

As superkdogg said, what modern CPU can do both those? The P4C/E can do HT but not 64bit, the A64 can do 64bit but not HT. Hmmm... Still, those are technologies that try to make a CPU "faster" but they currently do nothing for the capabilities of running software.

Try this on for size... find a piece of software on a store shelf that won't run (however fast or slow) on a Deleron. There's nothing in the world that requires HT. All the software (mostly downloaded patches) that "requre" 64 bit are basically a 64 bit port/rewrite/compile of normal 32 bit software.

 

[daveybrat]

well, i'm having the same problems as superkdogg. I've got a D0 stepping Celeron D 2.4 and it will work flawlessly at 2.9GHz (161FSB) on my Gigabyte 8IPE1000-G Pro motherboard at default voltage.
But even 2-3 mhz or higher at any voltage increase results in post, but windows will not load. I know the cpu has a lot more horsepower to give, but i can't seem to get around this FSB "hole".
And it's not the ram, since i've got it on a ratio, and ram is never running above 400Mhz.

Ah well, it still runs nice at 2.9GHz, i was just hoping for more

A colleague of mine has a 64 bit athlon setup running 64 bit fedora core and a 64 bit database and he said the difference between that and his pentium 4 32 bit system is night and day.

I agree with your last paragraph. The days of software requiring a "pentium" processor are long gone, however, I do remember trying to run software on a cyrix chip that would not run because it could not detect a pentium processor. I dont miss those days!!!

 

[D-Man]

Well as far as my 2.4 @ 3.8 OC goes with the Deleron it is rock solid. I would like to say this in the little chips behalf. I personally have the following machines in my home.

P4P800 Deluxe Celeron d 2.4 @ 3.8 2-512 Cosair 3700P
P4P800 Deluxe P4 1.8 (Dell Chip)@3.2 2-256 Crucial 3200
P4P800 Deluxe P4 2.6C @ 3.0 2-256 Elixir ?
P4P800 Deluxe P4 2..4C @ 3.0 2-256 Elixir ?
ECS N2400U 2500 @ 3200 Barton 2-256 Kingston 3200

I play many of the newest games backup DVD's Run Seti, etc and you can hardly tell them apart performance wise. I guess we could really get technicial and tear my statement apart BUT I belive a great number of people on this board doing the things they do on their machines could not tell one from the other.

I am very pleased to have run across this chip it puts a little fun back in overclocking and it brings us back to the old days when we looked for the best bang for the buck chip on limited budgets. I would bet this little chip of mine would give most users on this board a solid thrashing and the advanced users a good run for their money all for 72 Bucks what a value.

The latest Xeon CPUS(Nocona) can do both. They are HT-capable, and they support Intel's version of x-86 64(EMT 64).

Which desktop board can run one? I thought we were talking about consumer level processors, BUT, you do have a very valid point.

...So, let's all go out and buy $72 Noconas and run them on our $100 motherboards.

Bear with me

I'm new to PC's and overclocking (having been a mac guy for a long time)
So I decieded on a new 2.4GHz Celeron D with a ASRock P4S61 motherboard.
(I wanted to build a PC on the cheap) - so I popped in a 256MB stick of 333 as well.
All in all it cost me $300 Canadian for CPU, MOBO, CASE, PS & RAM.

So anyhow, enough pre-amble, I have had a lot of fun playing with the BIOS on this thing.
I only have stock cooling however, so I haven't done any "burn in" tests because I'm a little hesitant to blow something up. But the bus would go up to 180 no problem (3240MHz) - and the motherboard would show a temp of 41C, CPU @ 52C, and the built in fan startd to cross the 4000RPM threshold.

SO - I'm not really sure if I have a question or just to add to the comments on this chip, but I am impressed, and I may invest in some cooling so I can comfortably keep it around 3-3.2GHz.
BTW at 183 (3294MHz) it wouldn't POST, so 180 seems like the max unless I start fooling with voltage ans stuff. I'm not really sure I'm up to that yet

Anybody have any recommendations for cooling etc?

Here's my system:

Thanks a bunch,
Mike

Update:


As I suspected, my damn mobo was holding me back-big time! I put the same Deleron in question into...My wife's freaking office rig which has the SIS 661 Chipset and hardly any tweaking options. It fired right up with default voltages. So that 865 motherboard (one of the first to market at the time) had some sort of a problem with my chip and prevented me from getting the oc expected. Oh well. Now my wife's rig is at 3.6. She should be able to email REALLY fast! LOL

 

[SimonD1]

Hi

Superkdogg nice to see your wife rig do so well, what mobo has it got and when at 3.6 what temps are/were you getting?

I?ve been looking at the PCchips M863G, ECS-661FX and ASRock P4S61, which are all just about the same, with SIS661 chipset. All have fsb adjustment but the P4S61 look like it has voltage adjustment as well. Hopefully mike1979 can confirm P4S61 has voltage adjustment.

 

[superkdogg]

It has is an MSI I believe it is called the 661fm-L. At 3.6 it runs about 56 idle and never gets much above that because her rig is really just a glorified word processor. That's with the stock Northwood cooler on it. As always when overclocking YMMV. Good luck-I hope it works out that well for you as well. Of note: I had to choose between 166 and 200 FSB. If your chip only wants to go 198, it would not like my motherboard.


p.s. When I swapped with my wife I got my mobile Northwood 1.8 back. It's now at 2.76 with 1.76 vCore in my rig-(blatant disregard for Sudden NW Death Syndrome is shown). The two machines used to run at 2.4-P4Mobile and 2.76 (Deleron) the swap got me an extra 360 Mhz on the NW and 840 on the Celer-D. Nice little way to add 1.2 GHz to the family rigs!

 

[Zap]

WTG :thumbsup:

I kinda figured that everyone hitting a wall at around 3.2GHz-ish had some problems besides the CPU itself. Otherwise half the CPUs would only clock up to 3.2GHz and half would clock minimum 3.6GHz, with nothing in between. Doesn't make sense that way.

 

[superkdogg]

I can attest that my limit was an early revision 865 board and I suspect that may be the limit for most everybody-although I have no way to prove it.

 

[Zap]

The only way to prove it definitively would be to get together with someone who has a setup that doesn't hit 3.6GHz and put your chip in their board and their chip in yours.

 

[mike1979]

Hey SimonD1,
From what I can tell, the voltage adjustment is minimal - if any at all.
I have been combing through the BIOS and cannot find this option...
So I guess the naswer is NO, no voltage adjustment

Which is perhaps why I can't push this thing past ~3.25GHz
It seems to feel at home and stabl;e w/ a 178 FSB (3.22GHz)

Mike1979 thanks for coming back, it could be you PSU, not push enough amps on the 12v line, may be worth looking into???

ASRock web site led me to beleive there was an option to change the Vcore voltage, says it has "Hybird Booster" then states amoung other things it has "Vcore Voltage Adjustment: Provide a power up CPU core voltage adjustment interface"

So if you can't boost Vcore through Bios, is there a Wire trick like the AMD wire trick to increase vcore voltage???

I am AMD man but was hoping to try one of these celeron 320 and cheap all in one board with sis chip set.

I had a few M863ag mobo with barton 2500 running sis 741 Northbridge and the same 963L South bridge, some of the didn't like FSB over 178 but if you when in at 200fsb worked very well and solid but didn't like the low fsb????, so sis may have a hole in the fsb that the chipsets done like???.
