SV24 and C3 Ezra?

[zebedee]

I'm in the process of getting a Shuttle SV24 to use as a small server at home. It already has a P3 733 CPU with it, but I want to know if it will support one of the VIA C3 Ezra CPU's @1Ghz.

These processors run at 133 FSB, and I cant find out for definate if the SV24 will support a FSB at this speed.

If it wont support this FSB there are other C3 CPU's that run at 100FSB, does anyone know where they can be bought?

I want silence as the box will be used solely as a server running 24/7 and nothing else, so CPU power is not a problem. Also I want to passively cool the CPU so others are'nt really applicable.

think it should support 133 fsb - my sv25 does

why not keep the p3? it will probably give u more performance than an epia ?

[zebedee]

As I said m8 I want silence for this box and I cant run a P3 passively, I know the C3 chips can run passively. I agree the P3 will offer more performance but thats not what I'm after here. I have a SB61G2 with a P4 3Ghz, 1Gb RAM and a Rad 9700 Pro for performance ;-)

P3's below 1gig run fairly cool anyway. I'm sure a decent quiet fan would be a cheaper and better solution.

HP Brio's often run P3s up to about 800 passively, just with a fairly large heatsink and the power supply positioned over the heatsink so that the air goes straight out the PSU.

SO I think it's definitely worth a try as the P3-733 would be around the same speed as a C3-1GHz, possibly quicker.

I had an SV24 but I sold it on I'm afraid. However, I defintely know that the only difference between the SV24 and SV25 was tweaked voltages for Tualatin support; so if Hugh's right and the SV25 supports 133, then the SV24 should too. I may be able to find my manual for it, I'll have a dig through my spares cupboard later.

Even if it doesn't though, if it's not going to be doing much, you could run the C3 on a 100Mhz bus and either fiddle the multipliers (if you can... are they unlocked?) or leave it at 750Mhz. It'll still be fine for light server use at that speed.

Where would you be getting that Ezra from? I only got rid of my SV24 because it was so damned loud, if I could fit a quieter processor and do something about that evil PSU I could find a home for it again.

Dabs are selling the 1Ghz and the 800Mhz C3 processors. I was thinking of using a bigger heatsink and cool passively but I dont know if there will be enough room - I am thinking I'll mount the hard disk in the 3 1/2" bay instead of round the back so that may give me enough room. I havent got the SV24 yet (later this week hopefully).

Im gonna do as Glyndwr has suggested - I can run the CPU at 100Mhz FSB if it wont get to 133, and it will still be enough to do what I want it to do and it should run silently. Dont know about the PSU yet - I think it may already have been modded to be quieter - we'll have to see and sort that too as and when.

Am I right in thinking I can use one of the external PSU's with an SV24? Silimal to the ones you can use with Cubid cases?

Thanks for all the reples so far!

Hmm, they aren't all that expensive either. Now I'm really tempted to buy my SV24 back!

I think a passive PSU would be OK with an C3 and only one hard disk; it's what I had in mind. I'd like to get my SV24 back and get RAID in it (without an optical drive) mounted in the floppy and 5.25" bays; back-of-an-envelope calcs seem to suggest that might work, with not very many watts to spare. One way to find out!

I once 7volted the PSU fan in my SV24 but it got very hot, so much so that I went back to 12V. There is an alternative fan, but I don't have the specs to it now.

[zebedee]

I've been reading up on Adda 40mm fans that are supposed to be much quieter than the standard fans - Ultim8 PC web site has the details.

While I'm at it I'm also gonna change the PSU fan in my SB61G2 - the ICE fan is a coolermaster jobbie that is a lot quieter than the standard Sunon fan and cools just as well (plus the white LED's look good too- I get a nice white glow from the back of the shuttle that gets brighter as the fan speeds up - nice because I cant hear the fan!)

I wont need a RAID setup but I will need either a DVD or a CDROM in there too - so final specs will be Ezra 1Ghz, 512Mb RAM, 40Gb IBM HDD and DVD Rom. I think the 'brick' type PSU's should run this OK. Like you say - only one way to find out!!

Quiet fan would be 1 option but you can cool a P3 passively.

Have to admit I once forgot to connect the fan on my P3 1gig and left it encoding DivX overnite. Next morning I nearly pooped myself when I twigged but it was still alive. ISTR a P3 can survive 90 centigrade. Mine was around that or at least at some obscene temp. Unless you are gonna be DivXing ie normal CPU usage you should be fine. Get a nice copper heatsink of some size?

[zebedee]

Gonna see what I can do - once I get the Shuttle i'll try the suggestions and let everyone know how I get on. I may even try the P3 passively cooled - really depends on the noise as I'm gonna need some sort of fan to pull the hot air out.

Just found out the SV24 DOES support 133 FSB so thats one question cleared up!

I've read the Shuttle marketing spec sheet for the SV24 and it confirms this, just in case anyone else was wonderng!

Zebedee, where did you find that sv24 mate? I've been looking around for a sv24/sv25/fv25 for a few days now and can't seem to find anyplace that still stocks them in the UK. I'm looking to do exactly the same thing as you with regard to the C3/server so I'll be very interested in any updates in your experiments

As for passive cooled P3's I've seen a few of that speed in compaq machines but I do admit the HS were massive and obviously they had bigger cases and psu's

Oh look - 4 months in and my first post here shocking really but then there IS just so much to see.

[zebedee]

I'm in the process of buying it second hand m8 - only place you can get them nowadays I'm sure!

Just out of interest then if you don't mind me asking, how much are you paying and what sort of spec are you getting if its not just the barebones setup? I need some sort of guideline so I don't end up getting taken for a mug if I do manage to track one down.
