This is somewhat similar to the 'problem' I was having with my ATI-AIW 7500. Sound would only be on when I ran the initialization wizard. It would be off when tuned to a TV station. It turns out, I had a mute box checked somewhere in the ATI multi-media center. It wasn't the mute on the little...

I'm really hoping someone can answer my mobo - OS independence question, so I'm bumping...

You could disable ACPI in your BIOS. But then it's up to you to get everything right. I don't know what windows will do if it was installed with ACPI on, but I think it will boot. Have no idea what linux will do, if that's what you're running. Why do you want to do this?

You might also check that your CPU fan does not blow on to your PS. I had a similar problem, the computer would freeze when doing anything that demanded a lot of power, like a game. I put it together on a shoestring and the case was small. The problem turned out to be the CPU was partially...

I think my mobo is dead, but thought I would ask before I totally panic. You see I work from home, and this is my central computing center, if you will. The hardware is nothing, it's all the time I have spent getting everything correct. I have to get it back, and that means to hell with...

Oh my God. It's only a 250W PS. I'm hoping that this microATX MB needs much less power. I have not purchased a vendor PC in quite some time. But I was spending too much time building my own, so I went this way. I have been going for 350-400W PS's on my home-built systems just to be one the safe...

One other thing. THe smaller gate lengths inevitably lead to larger leakage -> higher off-state power. And in general for the high-performance transistors nobody cares, which is why these things are burning up. The M will be a lower off-state leakage by decreasing the short-channel effects...

I disagree. Why do you think they're more densely packed? It's because the gate length is shrinking. The speed (saturation current) pretty much scales as one over the gate length. This is true until we reach around 40-50 nanometer gate lengths, although other issues are coming into play also...

THanks mechBgon. So, is it that I had the drop in performance bandwidth according to Sandra because it averaged across the 3 chipsets? That is, two of them running DC and one of them SC? I think that would come out to about 33% drop. Yeah, I have another vid card to put in. Just haven't found...

Thanks 3chordcharlie. Looks like I'll be buying another 512 stick. I'll have to find another home for these 256 sticks...

Looks like I lost LTC8K6. Can anyone tell me: Does the matching only have to occur on the same colored slots? If I put 2-256 in the blue slots, and 2-512's in the blacks, would my performance decrease from the 2-256 case? I have obtained the best bandwidth performance with the 2-256, and I'd...

Good point Pariah. Nonetheless, faster transistors mean better performance. And faster transistors have generally been obtained via smaller footprint, which means higher density. My point is we're reaching the physical limits of speed, which is pushing for architectural changes... SkipE

calam63 Interesting. When I use the Crucial System scanner, that's what it says my MB is. The one I have is a microATX board, so perhaps it's the same as the p4sdx, only a micro form factor.

Light only travels about 3 cm on a board at these frequencies. That says nothing about the noise these signals generate at these frequencies. I think it's amazing we're at this blazing speed. Physics is beginning to dictate that we start looking for architectural changes for better...

Wow, thanks LTC8K6. Yes, I've got two blue and two black. And yes to the P4SD. But I couldn't find detailed info on it on Asus site. So, what happens when I have the 512 in a black slot and the 2-256 in the blue? Does this matching only have to be according to slot color? SkipE

Well, there's a lot of ideas out there. One of my colleagues proposed a kind of via approach for better cooling and received a patent for it. I worked on the SOI heating problem for about a year. It's been a while, but I'm not sure it is as bad as first thought because the duty cycle is low...

LTC8K6, now ya got me worried and confused. Anyone else only see a 5% drop?

Markfw900 No, I put one 512 into it and it had 2-256, for a total of 1GB. That's when I saw the drop in bandwidth performance...

It's an HP Pavilion A465C, and it says it's some kind of Asus board. It must be specially made for HP because I can't find the particular model # on the Asus site. But it must have dual channel capability, otherwise how would one explain the 33% drop in Sandra bandwidth specs when adding a 512...

Thanks Nick1985. So would it be better to run two sticks of 512 or 4-256 for best memory performance? I need 1GB. Thanks, SkipE

I have my first DDR machine and am still confused about this newer memory spec. I posted yesterday about DDR, and from the replies I'm getting the picture that there are two things, not one. Please correct if I'm wrong about this. THere is DDR and there is dual channel. Is this correct? I...

I believe that SOI only increases heat problems. The thermal conductivity of oxide is two orders of magnitude less than single crystal silicon. So it's more difficult getting rid of the heat, unless there's good methods for ridding out the top. But the numbers I've seen can only reach 50/50 out...

Hey Markk, Although I am no expert by any means, I have some experience. I've tried all the jet's; jet this, jet that. And they are basically a pain and expensive. True you can buy these do-it-yourself kits, but I walked around with the blue hands for days afterward. Now it seems there are a...

Hi, My first system with DDR memory; specifically PC3200. It currently has 2-256M sticks. I don't know the brand but the factory default timings don't look that great. I can't reboot to see the timings again as I'm updating my linux system and it's going slow. If memory serves me correctly they...

Thanks Belzer. That was the article I was referring to. hahher, I would recommend that article, and you form your own opinion... SkipE

No expert here, but at one time I found a rather detailed explanation of the differences between +-. Sorry forgot where it was. Guy seemed to very much know his stuff, and had the details to back it up. Anyway, according to him the + is much more robust, both in terms of speed and just simple...

I bought a Maxtor 160GB drive a few months ago. I think I have the same card as yours. I was never able to get the card to work. My nephew does this for a living and it couldn't get it to work either. Actually, that's not the whole story. I could get it to function under Windows 2000, but linux...

Bought a new 512MB stick. I have two other sticks of 256MB Crucial memory. New one is a no-name brand. Put it in and booted up but system didn't recognize the new stick, or at least it didn't show up as present. Thought perhaps the slot was bad. Took the two Crucial's out, and inserted the 512...

Tough one nboy22. I'm not going to be much help unfortunately. Have a linux CD handy? If a minimum setup loaded and booted without issue, I'd suspect something wrong with your XP CD. Don't know how much help this would be, and it's a lot of reading, but you might take a look at...

I see all these great deals for 512 MB sticks of the newer memory, but the stuff for my system remains over $100 everywhere I've looked! I have two old KT133A Via chip MB's I would like to add 512 to. Can I use this newer stuff on my old MB's? If it makes a difference, one is an EPOX, while the...

Forgot to mention - I have had good luck with SMC, and they're usually cheaper...

Get a router - it will serve as a firewall also... SkipE

I tried like hell to get the price down to that level on their web site. Closest I could come was $746. What am I missing, connections? :) SkipE

Can someone tell me where to find more info on this problem? I have been trying to chase down a problem on a system with this hardware which only occurs under linux. I hope this is indeed the cause. It has been driving me nuts! Thanks! SkipE

forgot to mention i can't get to my w2k on the hard drive to make boot floppies. SkipE PS I have NT running on my laptop, can i make them from NT?

I couldn't find anything in the manual stating not to put the cdrom on the high point controller, but i switched it anyway. as well as the hdd's. it does the "detecting ide drives" thing during POST, but doesn't find anything. i thought maybe it was because i was still using the...

I changed to the correct cable (blue on one end), but didn't help. Poof, do you recall any web sites by any chance, that dealt with the high point and w2k? Thx, SkipE

I press the enter key when it says press any key to boot from the cd-rom, that's when i get the nt loader error. If I don't hit a key, it goes to the hard drive (where i have lilo loaded). SkipE

Well, couldn't find anywhere in the BIOS a "flag" for bootable. I did set the CDROM as the first boot device, but still same problem. Currently, and perhaps this is part of the problem, I have the CD attached to the UIDE (HPT370 controller) connectors, because it didn't find the CD if...
