[DEAD] Celeron 633 $17 @ Directron, free S/H

[Ionizer86]

Celeron 1.1 should be Tualatin. In that case, its performance shouldn't be much worse than a P3. Maybe I'd say a P3 1.0 EB.

There is an overlap in Celeron speeds between Coppermine-128 and Tualatin-256 cores:
Coppermine-128 cores (128KB L2): 1GHz, 1.1GHz
Tualatin-256 cores (256KB L2): 1AGHz, 1.1AGHz

That's why those 2 Tualatin-256 models have the A suffix.

compgeeks had both the coppermine-128 1GHz and 1.1GHz in stock yesterday when I checked. It shows 2 of the 1.1GHz CPUs in stock for $41 each, -10% = $36.90 if you have a discount code since it's not a "geek special". Some other places on pricewatch show a similar price and both models.

thx for the info, so the coppermine 1.1 ghz celeron from compgeeks wouldn't be much of a performance difference from a p3-450 then? I'll go look it up if there are any benchmarks online.

A Coppermine Celeron 1.1GHz IS a huge performance increase over P3-450 for most tasks. Of course we're not talking about a modern performance level, but to put it in perspective a 1.1GHz Celeron would have about the same (average) performance as a P3 @ 950MHz.

On the other hand, if you need buy a slotket adapter it might be a better longer term bang-for-buck upgrade to just replace the motherboard too, opening up lots of choices for the CPU.

Yep. A coppermine-128 Celeron 1.1GHz is around the same speed as a P3 900MHz (100MHz FSB).

Since these are still available, I thought I'd give it a bump. Considering that the one I received is running at 1064Mhz at default voltage, this is a sweet deal (and it may go higher, i haven't even tried yet).

Alice sends her thanks!

 

[pigseye2]

cool! thanks for letting us konw Dran, I'm still waiting for mine to arrive. should be later this week.

[mindless1]

Mine came today, hits 950Mhz at default 1.7V, but no post @ 1064MHz on a cheapo ECS board. Didn't try raising voltage though. It's a SL4PA, cC0 step.

 

[randomlinh]

damn.. all i need is a cheap board and boom, mini server is back for me!

Please pardon my ignorance in such matters:

I have a Compaq computer running on a 565 Celeron (coppermine).

Am I to undersdtand correctly that switching out the CPU, without changing the voltage settings will, yield a 950 mHz speed? Why wouldn't it just run a 633? Why doesn't the 565 run faster at default?

I was going to buy a FCPGA-2 adapter and a 1.1-A flip chip to replace the current processor, but at a third of the cost, I would happily consider taking the slower CPU speed. I'm looking to get the system to the point where it can run Snap Stream at least at minimal configuration (700 mHz PIII). I'm assuming a Celeron at 950 mHz would at least be comparable to that.

The only worry I have is that I remember reading somewhere that the Compaqs weren't overclockable...is this true??

Sorry about all of the questions....like I said, I haven't really touched on this area much in the past.

In order to run a 633Mhz CPU at 950Mhz, you'll need to change the FSB (Front Side Bus) speed to 100Mhz. Your computer, and the 633Mhz CPU, operates on a 66Mhz FSB. It might be a jumper or dipswitch on the motherboard, which will be labeled either on the board itself or in the manual, or it may be a setting in the BIOS. Either way, before you even attempt the change, you'll need to check your memory and verify that it's capable of operating at 100Mhz. You can do this by examining the printing on the chips on the DIMM(s) and looking them up online.

I'd highly recommend that you do some research first. Read up on overclocking, what the risks and dangers are, before trying it. It's very, very easy to ruin perfectly good hardware if you're not careful. That said, I'd also recommend you try to find the 100Mhz setting for your computer, if it has one, and see if your current CPU will run at 850Mhz first. You may find that to be enough of a performance boost to save the $17 you would've spent on the 633Mhz Celeron, which could be put away toward a faster machine (you might even consider building your own).

Well, whether it'll be comparable to a P-III 700Mhz will depend on the memory used and how well the chipset on the motherboard runs (or how well it can be tweaked). I have the 633 I bought running at 950Mhz right now (stability issues at 1064Mhz, though not certain whether it's the board or the CPU. not the memory, as i have two of the exact same DIMMs running at 112Mhz in another system, perfectly stable. must test some more!), and it's turning in SETI@home times that're about comparable to a P-II running at 450Mhz (that other system the memory's being used in, a P-II 400 @ 448Mhz). So the raw CPU power is a little higher, but because of the much smaller cache (128K, as opposed to 256K on a P-III, or 512K on a P-II), the increased CPU performance is diminished.

The only worry I have is that I remember reading somewhere that the Compaqs weren't overclockable...is this true??

A lot of systems/motherboards aren't overclockable, and it's likely that your Compaq won't be any better off. However, one must keep in mind that most systems, even ones built by companies like Compaq, are designed with at least some upgradability in mind, and since yours was based on a P-III CPU (FC-PGA Celerons are simply Coppermine P-IIIs with 1/2 the cache), it's also very conceivable that Compaq left an option somewhere to upgrade to a 100Mhz CPU. If they did, as I said, there'll be either a jumper/dipswitch or a BIOS setting that'll allow you to bump the speed up.

 

[lungster]

To add to what Dran has said above, Compaqs are generally not very easy to tweak - it's their way of avoiding service issues as well as getting you to buy upgrades. But that doesn't mean it can't be done. In the old days, Compaq used to design and build their own motherboards; those were very closed systems. Today they mostly buy from motherboard vendors who custom make a BIOS that says "compaq" on it. If you can find out the make and model of the OEM mobo, you may be able to re-flash it to a more generic model that might be friendlier for OCing. For example, I used to have one of their old Pentium 2 440LX based Intel motherboards. I reflashed it with an Intel BIOS. If all this sounds problematic, it is ! OC in general, and even more so playing with BIOSes is not for the faint of heart. I'd never do it to a machine that I use and need regularly (daily ?) as the probability of failure is high and that will put your system out of service.

 

[mindless1]

I wouldn't expect a FSB jumper or BIOS setting on a Compaq S370 board, it may be easier to just break off the BSEL0 pin on the CPU, which is how a motherboard detects the FSB... with the pin connected on a Celery <800MHz, the board uses 66MHz FSB, but with no pin (or factory disconnected pin) it'll run @ 100MHz FSB. Of course this is assuming the particular CPU will do 100Mhz FSB, 950MHz, and that the board's BIOS doesn't complain, which it shouldn't if it has support for a 950Mhz Celery or P3.

The last Celery I bought from Directron (after they were already old tech) was a 700 or 733Mhz. It would not run stable at > 1GHz no matter what Vcore I tried. This doesn't bode well for old Celerons from Directron, but it's a LOT easier to get one running at < 1Ghz (950MHz). I'd think it's a likely, reasonable goal but no guarantees of course..

I think you would need the correct stepping as well...

 

[kctopitz]

Will the mentioned Startech.com slocket run this chip at 100MHz FSB if the motherboard has no manual voltage control? I'm assuming it won't, and the only slocket I've found with manual voltage control is the Asus which runs about $35 shipped from what I've found. Anyone know what happened to the praised iWill Slocket 2?

If anyone can advise, I've got an old Dell Dimension XPS R400 (Intel 440BX board) and looking for a cheap jump at least above 700MHz.

 

[mindless1]

kctopitz,
the primary issue on your board would be coppermine support, whether the BIOS allows it or "unnecessarily" halts. Many Intel boards had a bios that would allow using Coppermines, but IIRC, in some cases Intel caused the last bios versions to halt, so ideally you might need the second or third to last bios available, not necessarily those versions available from Dell, but from Intel (maybe Dell's would work, i don't know). Your board "might" be same as a "seattle", SE440BX, though that's just a guess.

As for voltage, the board might support 1.7V, no change needed, or you might need to up it to 1.8V. If you do need use 1.8V, a slotket with this option is certainly easier but you could instead either solder two adjoing pins together on the back of the slotket, or wrap a tiny piece of wire around these same two of the CPU pins (VID1 and VSS). This is assuming the CPU starts out with 1.7V default, and you'd need be sure the wire (or solder) only connected those two pins.

Does anyone know if this cpu would work in a LX chipset board? Just wondering because I have a Gigabyte GA686-LX motherboard as well as a FC-PGA compatible slocket sitting here. I have the latest bios on it too from 10/01 that suppose to support 75GB HDD's or so the Gigabyte website says. Anyone have any ideas?

 

[SimMike2]

It might be possible to get a coppermine chip working in an LX board, but don't count on it. First you would need a slot 1 to 370 adapter that allows you to control voltage and possibly multipliers. Then you have to hope the BIOS of the board doesn't freak out. If the mainboard really freaks, it won't work, or it will work in a very crippled fashion. The next step would be where the BIOS incorrectly identifies the type and speed of the CPU, but when you get to Windows and check the speed, it is what you want. Unless you have a slot 1 adapter already, I would not bother trying the "upgrade."

I just reread your post, and it sounds like it is worth a shot. The BIOS date is relatively new for LX boards.

I am using this slotket:

StarTech PPGA/FCPGA-to-Slot 1 CPU Adapter Card allows Socket-370 type CPUs to be installed in a Slot-1 style Pentium II/III motherboard. The processor bus frequency can be auto-detected at 66/100/133 MHz in order to provide best compatibility between the CPU and motherboard, or it can be forced to 100 MHz for overclocking.

Wouldnt a duron 1.3 for 26 bucks be better?

 

[cmetz]

mindless1 et al.: is there a non-destructive multiplier hack? Also, I'm using a Slocket, is there a non-destructive hack that could be used in the slot 1 edge? If all else fails, I'd rather x-acto a trace on the Slocket, but it seems to me like there should be a clear nail polish or similar hack.

 

[kehi]

Nice deal

 

[KennyH]

Thanks SimMike2! Anyone else have anything to add to the LX idea?

 

[DJMiX]

How do u hack the multiplier?
Aren't all celeron's Multiplier LOCK?
