The change between C0 and CG was quite bigger in terms of undervolting. My C0 can only run stable at 1.35v @ 1800Mhz CG can run stable at 1.1 @ 1800Mhz. This must make quite a big difference at load. D0 is suppose to be better than CG but i don't think anyone has anyone has posted undervolting of th...

I often have lots of tabs open, bad habit from pre-broadband days.
It sometimes scares me how much memory firefox uses when you have over 5 windows open!
I got 5 tabs open at the moment and it's using 66Mb of memory!!!

I just went to Asus BIOS download area to see if they had released anymore BIOS's for my motherboard. They had in fact got two newer than mine, 1003 and 1004. The 1004 is the one that interested me most. It said on the list of improvements that a new CPU had been added! Confused i went to the link p...

Well in terms of cooling a CPU Moving from worst to best: Passive Fan Water Phase Change PSU are mostly Fan cooled because it is low cost, but if more cooling performance was needed than a fan could provide. Then the next step would be water or phase change. When you think about it, water is the med...

Thanks for pointing that out Mikael, i should have really mentioned that! :oops: I was looking for that article at toms but i couldn't find it! If the figures from tomshardware are accurate then the Athlon should be using about the same power level as your current P3 1 Ghz. Cool and quiet makes a go...

This Article at Anandtech should give you a rough guide to the differences in power consumption which in turn shows the amount of heat they will be kicking out.

Athlon 64 90nm, socket 939 is the way to go at the moment.

Suspension is a very cheap and effective way to reduce hard drive noise and vibration. I just did it with my samsung and the difference is unbelievable i can't hear the seeks anymore. I would say its as quiet as my Nexus NX3000 now. Its a cheap mod too, £1.50 to buy the elastic 10 minutes fitting ti...

There are three utilities which will do what you want. Clockgen allows you to change speed with the click of a desktop icon. Crystal CPUID is in my opinion a better tool than clockgen and is what i am currently using. It allows you to make a three stage cool and quiet and adjust how long it takes be...

I just suspended my Samsung P80 using £1.55 worth of elastic. The difference is amazing!! I was getting really fed up with my case vibrating and rattling, I was pretty sure it was the hard drive so I brought the elastic. Took about 10 minutes to fit, I used up the entire 3 metres so its not going an...

WOW that is one good chip!! That can't be using more than 30w at full load, truly brilliant. Unfortunately for me i got a clawhammer, which doesn't like going under 1.3v @ 1800Mhz. When it's locked down to 0.975v @ 800Mhz the temperature doesn't rise above 40c with the fan off. Speedfan turns the fa...

Having owned my Samsung drive for over a year now i can tell you, there is no way i would choose another drive which hasn't been tested by SPCR first! I believe overclockers uk sell the NIDEC's motor drives from what people have been saying on here, though don't hold me to that as i brought mine els...

I have a Asus K8N which is the lower spec version of your board, but the BIOS appears to be similar. Tibors suggestion will allow the motherboard to boot without pressing F1 but it will cause your board to beep violently. Your best bet is it to tell the sensors to ignore the readings. To do this, go...

Thanks rperezlo, i'll have to give that a try some time. I'm pretty sure i have some silicone gaskets around here some where. When i first looked at it i thought that maybe a single screw will do the job but decided to give the stock fan ago.

I have a stock heatsink on my Athlon 64 2800+. At full speed it is annoying but luckily my motherboard (Asus K8N) has a BIOS based fan controller. I tell it to start the fan when it reaches a temperature of 45c. If the fan starts it is set to 5v and gradually increases from 5v to 12v if the temperat...

If there the things i think they are, then they are really effective at reducing noise. When i took my Tivo apart the hard drive was mounted on four of these EAR washers. The drive was a Maxtor, which has never bothered me before, it always seems very quiet in the tivo. I took the drive out and hard...

Ed, do you think it would be possible to just switch the fan off all together?
I read somewhere that the old cooldrive 3 had a fan and even with it switched off it still dropped temperatures a little bit.
The design seems a bit like the smart drive enclosure rather than the deadly 'silentdrive'!

Tibors its ok, i wasn't confused. It's Nexus naming that is confusing. NX-3000 = 300w NX-3500 = 350w NX-4000 = 400w NX-4090 = 400w? what’s the 90 for? Would it not be better to call it NX-4012, to imply a 12cm fan? Not that it really matters of course, a names just a name. I'm just being picky! :lol:

I have seen that before but usually i tend to take sound readings with a pinch of salt. Nexus seem to be one of the few companies that give a 'real' sound reading rather than just using words like 'silent' and '26db' readings. *cough*Coolermaster*cough* When its closer to 40db and more like a jet en...

Have had 4090 for a couple of months. Extremely happy with it :D I run a reasonably thirsty system (P4/2.66, 4 x IDE drives, 2 x CDRW, ATI 9800Pro) and find it completely stable and a very low noise PSU. Beat the previous Nexus 3000 I had (also decent PSU but donated to other system). cheers, marti...

Thanks to my lovely new Athlon 64 i have joined the underclockers. Currently i use CrystalCPUID with three speeds. 800Mhz @ 0.975v (Mostly in this state) 1200Mhz @ 1.1v 1800Mhz @ 1.35v In the lowest p-state i can run the processor with the stock fan off! It is also fine even under full load, if it's...

If one looks up the "old" 3700+ and 3800+ in the document, they both have powerstate 2200MHz@1,4V, in which they both consume 72W. The "old" 3000+ has 1800MHz@1,4V; wattage 66/67W. Coincidence? I hope that someone has saved a version of the document with the mobile chips in. /Me wants it. :D Cheers...

These chips use aproxamtly 25% less power than the equvilent 130nm chip but of course it's not as clear cut as that. The 130nm uses 0.1v and 200Mhz high clock frequency. So the gap is more like 10% - 15% everything being equal. The higher the clock speed the bigger the difference but at lower clocks...

I'm not sure how common the cold boot issue is with Athlon XP but in my view the Athlon 64 can be set to start reliability and changed in windows. For me this potential problem would be the deciding factor, now that the prices are not far from each other.

Still if you know something new is coming out within a few weeks of your purchase, you would be kicking yourself for not waiting.
Still i know what you mean.

The one certainty in the universe......your PC will always be out of date!

The motherboard voltage regulators should be able to handle the change in voltage, after all they boot from 0v to 1.55v just fine.
Maybe its the FSB changing instantly that it doesn't like?

You can run the Athlon 64 at 800Mhz, with a 4 multiplier. To go lower you can lower the FSB to get a lower frequency. Clockgen should allow you to do this in windows with nforce3 boards.
Please correct me if i'm wrong.

That looks quite interesting. The sempron at 1.5v uses 8w more with load than the same chip at 1.4v. Which means that these 90nm chips are making about a 12w difference based on the manufacturing process. The other 8w is a result of the lower voltage. That’s my guess anyway. The only question is doe...

Looks like 90nm may have a major advantage over 130nm after all. It would have been nice for them to test them at the same voltage, but to my mind that gap is too big to be explained by just 0.1v vcore difference. http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2249&p=13 I was so set on that 280...

AMD = underdog, yet with a better product, lower price, low power consumption and lower heat. AMD's problem is there marketing is poor at best, they need to built a strong public image so that joe public go "Let's buy AMD because they are just as good as Intel but not as expensive to buy and run" Ma...

A drop from 1.5V to 1.4V could be significant or insignificant. I use my socket 754 A64 at 1.25V already. What's important is will the 90nm chips allow better undervolts or are they just 1.4V "certified" and no different from current chips. The 3100+ 1.8Ghz Sempron runs at 1.4v default but the Athl...
