DDR 400 mhz running at 266mhz less heat?

Post by fabre » Sat Mar 27, 2004 2:50 pm

Would DDR 400 mhz running at 266mhz produce less heat than running at stock? or they don't produce that much heat anyway?

I am looking for some memory to run with an MOBILE ATHLON XP-M 2500+ in a small case with little airflow at athlon stock 266mhz (antec minuet)


Antec minuet
ASUS A7N8X-VM
MOBILE ATHLON XP-M 2500+
ARCTIC SILM SILENT PRO TC FOR AMD
2 x 512
PowerColor Radeon 9600SE 128MB (low profile)
MSI VOX TV BOX USB2.0 EXTERNAL TV-TUNER
Liteon combo cdrw/dvd

Also between a SAMSUNG SPINPOINT 120GB (SP1203N) and a SEAGATE BARRACUDA 7200.7 120GB ATA100 7200RPM 8MB (ST3120026A)
Which one heat less?

DDR memory does run hotter at higher speeds, if the voltage is constant, but he actual heat dissipation numbers are so small they can be dismissable in almost every case, where there usually are VGA cards and CPUs whose heat has to be dealt with.

Yup - my DDR400 is spec'd at 3W (1.2A @ 2.5V) so you are in peanuts territory here.

thanks for the confirmation. :D

Otherwise is the Samusung SP1203N as quiet as the recommended Samsung SP1604N? or will I be better of with a SEAGATE BARRACUDA 7200.7 120GB ATA100 7200RPM 8MB (ST3120026A)?

and subsidiary questions: would a passive low profile powercolor 9600se 128mb be a great improvement in performance (games) over the gfx4 mx of the ASUS A7N8X-VM? (enough to justify the heat increase)

Hi,

The Samsung 1203 and 1604 should be the same noise - I am guessing they both have two platters of 80 gb each. The Seagate 7200's are noiser by far. The Samsungs are great drives, snappy, fast and quiet. I actually wish there was a higher seek noise (I am a bit of an old-timer, seek noise means computer is doing work heh.)

A reminder to check the recommended section, Mike has done a great job on many components.

http://www.silentpcreview.com/section10.html

As for the video card.. For a budget-conscious card I was going to recommend a Ti4200. I checked the price, however, it's around $130. For the same price you can now get a 9600 pro!

You can get an ATI 9600 Pro for about $130 and spend $30 on a Zalman heatpipe or an artic cooler.

The Sapphire 9600 Pro Ultimate is passively cooled, I think. Costs $160.

Battlefield 1942 on Ti4200 I run at 1024*768, medium details. On high details it will suffer some lag in the big maps.

On the 9600 Pro, I can run 1024*768 or 1280*800, with some AA/AF (x2,x4).

There is a recent thread on the power output of the various cards. IIRC the 9600 Pro emits somewhere around 23 watts worth. Compared to the 90 watts of a CPU, it is fairly trivial to cool silently.

I looked at some of your components - I am not familiar with your choice of heatsink, again I'd stress taking a look at the choices available.

wisefool thanks for your advice but all the video cards you mentioned are full size cards, where the minuet accept only low pofile cards (half height).

Can anyone confirm that?

if one is counting every single watt of heat his computer puts out, is there a motherboard capible of undervolting ram? below 2.5? my pc 3200 has to normaly run at 2.7 volts but at 2700 i run them at 2.5

at stock they do get hot to the touch, and the way i run them now they run only slightly warm. would that contribute to long term stability?
