but I hope it does have a pc speaker header
What's the difference. I have always preferred mainboards that have onboard speaker (buzzer) because it is one less thing to hook up. It isn't like anyone is using the PC speaker for a musical instrument like we were 15 years ago. Most people just listen for the sweet one beep when we boot the computer and that is the last we want to hear anything from that tinny speaker.

Just got mine..

1. The board is pretty small! Smaller than the K7S5A series boards.

2. Looks like most boards are coming with the BIOS soldered and mine is no exception. But mine didn't come with an AMI BIOS like some have been getting... it says Phoenix BIOS on the chip.

3. There was no speaker1 header and I guess that makes sense since it comes with a piezo speaker built-in

4. Mine has no 1394a port above the first two USB ports.. It just has the onboard LAN and 4 usb ports.

5. It has 4 holes near the socket A

6. It has the multiplier jumpers next to the serial ports/parallel port

Going to install it now.

"L7S7A2 hits 250 MHz " Is the title of a post in the ECS forum on OCworkbench.com. That's some sweet memory!
SiSoft Sandra screenshot shows fsb at 200Mhz and memory at 250Mhz (500Mhz ddr).
"CPU=200 MHz FSB, Ram=250 MHz (= PC4000) I may have struck gold with that Samsung PC2700 (CTL)."
"CPU is a 2400+ with multi 11 which gives 2.2GHz at 1.95V vcore. Memory is at 3V vmem but not especially cooled. Unfortunately, it is not completely stable at that speed. Windows is fine but Prime95 gives errors. "Timings in BIOS: CAS 2.5 and 'Normal'".

So far, with the Crucial 512MB PC2700 DDR I got from the CNETPC thread, I have hit 180MHz FSB using Normal setting and 2.5T.
Will try for more later... This gives me almost 2GHZ on my Athlon XP 1700+ TBRED B JIUHB

Just an update since I got a PM about this...

The GC68 HSF does fit on this motherboard just fine! Anything bigger and you might run into trouble since the capacitors are
close to the socket.

Also, there is no cdin2 header on this motherboard (at least on my revision 1.1 batch 0).. so it takes the standard black 4pin audio
cable connectors, not a "mini" one with a white connector... So it looks like I'll have to get a new cable or find a spare black
connector and replace the white connector on my cable...

why the need..? WMP7 and better uses your IDE ribbon for sound..

I didn't know that... but I did try to play a DVD the other day on my DVD-ROM drive, and without the audio cable connected to the motherboard header I got no sound... hmm... but it was using PowerDVD, not WMP... it only works with WMP7?

running XP here but when I was using WMP7(WMP9 is latest..I believe its WMP4or6 in Win98 unless upgraded..used DirectX7 then 8.0a now using 8.1) even MusicMatchJukebox,RealPlayer,WinAMP,Divx4, and WinDVD played without the analog audio cable.

Yeah, you just need to root around PDVD's options and find the option to enable it in there.

EDIT: I am now a Senior Member! w00t! That made my Monday.

I've finally started to ditch my PC133 (had almost 3GB of the stuff until recently), and can only report that I've had no regrets, even if my main system has "only" 512MB of DDR now, compared to it's former 1GB of SDRAM.

For the people having trouble with audio: firstly, I don't think playing DVD's ever makes use of analog cables - there may be some feature you need to tweak in your player software. secondly, (under XP) - you may have to manually enable digital transfer for a drive: Device Manager -> CD/DVD Drive Properties -> Properties Tab - > "Enable digital CD audio for this CD-ROM device".. Of course, if Windows hasn't enabled it for you, that may be an indication that your drive doesn't actually support it..

Hey zeroidea, you looking to get rid of any more PC133? I'm need some for a server I am building. PM me if you're looking to offload some of that.

In response to someone stating above that Tom's Hardware said the K7S5A was a great board. They later changed that opinion to not so great. It would seem that they sent a very special reference board to Tom's for testing/evaluation. Whilst the majority of the other k7s5a's were not of the same quality. Thus there were some major problems. It would appear that at least half of the k7s5a's that came off the production line had seriously picky power/memory needs. I know this for a fact as I built roughly 10 systems using these, per Tom's recommendations, and had 4 of them with bad motherboards. Wouldn't boot, video errors when they would, would power up but not display anything and no post beeps. Thus after learning this Tom's hardware switched their opinion on the k7s5a. Now they say its touch and go with ECS as some of their products are good and some are bad. I personally will never buy another ECS product. Their tech support was anything but helpful when the company I went thru refused to rma the board for me (www.cpusolutions). They told me that I had obviously put the system together wrong thus the problems...yeah right. So its Asus only for me. You can't go wrong with an asus. i've built 50+ machines and never had an Asus board go bad. In fact my brother is still using my amd k6-550 on an asus p5ab, almost 6 years old or more. As always YMMV but I'll never touch them again.

Codeloss did you order from Newegg or elsewhere? I got mine from Ateck and it came with a backplate.

I have a client with an ECS K7S5A Pro, and it is a stable reasonable m/b running at standard parameters. Don't get me wrong, I'd never buy one of these for myself, but considering that it cost her $44 +tax, she got a good deal.

I got an SVC GC68 for about $10 at SVC.. not sure it's rated for use with a 2400 xp but I got my 1700 OCed to about that speed and it's working fine.

Thanks corinthos!

Looks like the GC68 does not or untested for 2400+.
But I got the GC88 for $15.

GC-88 copper & GC68 aluminum mini review:

GC88 Prime 27c/53c case/cpu.
GC68/GC118 Prime95v21 28/52c.
Very similar performance with tests on 1600XP Palomino 1.75 Vcore 1674Mhz.

Stamped copper base came with a hard clear coating.
HS needed extensive lapping to get it flat and smooth.
3500 rpm 29db fan actually runs at 4000 rpm. Noise not bad but still more than the claimed 1dB above GC68 levels.
Spring clip is much weaker than GC68, but seems to do the job. Easy to place off-center and HS can be slid about.
GC88 blows sideways toward dimms and GC68 blows up and down toward pci slots and psu.

Tbred 1700 @ 1.8Vcore 2011 MHz K7S5A sensor GC88: idles 25c/40c, Prime95 burn-in 26c/48c, web surfing now at 27c/42c.

Athlon 1600XP 12.5x AS3 1.75 Vcore lapped GC68
1674 Mhz 133fsb CpuBurnK7+RunPrio two 1 hour runs 57/28C 0.436 C/W , then Prime95v21 52/28C,
then 44/27C idle.
GC88 installed (well centered on chip, but the clamp is not very strong) with AS3,
1674 Mhz 133fsb CpuBurnK7+RunPrio 1-1/2 hours 57/27C (peak 58/28) C/W 0.451, Prime ok 1 hr 53/27C.

Both are good for the price, but not able to dump extreme amounts of heat. My GC88 was $11.50 delivered from a pricewatch vendor.

I just received this mobo from NewEgg $66 shipped. I looked at the specs and it doesnt match fully with what my mobo came with.
In the specs, it is written that there are 2 Audio connectors on the motherboard, which you could typically use to connect 2 CD-ROM devices. Mine has only 1 - the black one named CDIN1. The CDIN2 is missing.
Also, the specs talk about support for 2 case fans, named CHSFAN1 and BAKFAN1. The latter is missing from my mobo too.
The CDIN2 and BAKFAN1 are present in the photo on ECS website too. Dont understand why its missing from my piece.
Did anyone notice similar missing connections on the motherboard. I wonder if I've got one of the bad pieces, and I have to return it for a replacement.

A related question. I noticed that there is a capacitor very very close to the socket. Did anyone have particular problems with installing a heatsink on this mobo? Im thinking of buying the Aerocool AWBK0168 from Nexfan http://www.nexfan.com/aeawcosa.html. Does anyone have an experience with a similar sized heatsink/fan ?
