Are there ANY LGA775 chips that run cool?

Sumanji · 2 May 2006 at 15:16

As title really... I really wanna go Intel on my HTPC but I can't afford a PM + desktop board so LGA775 is the only viable route

Are there any cool running chips?!

Cheers,

Suman

The 9xx series run on a 65nm fab so they run cooler...why not just get an AMD?

Gashman · 2 May 2006 at 17:12

yeah rakiri has it in one, a pentium with a cedar mill core, any 600 series ending in 1 i think is the ones, but hes right again since even though 6x1 series run cooler than the older 90nm parts, they still run hotter than venice/san diego with no performance improvement, they consume more power, generate more heat and i think there still slower than athlons, seems odd choice?

Pentium 4 631 (3GHz), 641(3.2GHz) run cool enough to make AMDs look hot. I'm told they run at 25C with a decent cooler.

Gashman · 2 May 2006 at 22:44

right if cedar mills run cooler than athlons there still beaten in performance, value and power consumption, still seems weird for anyone to choose a pentium over a cheaper, better performing athlon

Celeron 65nm maybe? (they have 512k cache now, so not as weedy)

well my pentium d 920 runs at 36 degrees under load at stock (the pwm temp is higher!), this is an aspire x-qpack matx case with stock heatsink and fan and a single120mm instake an a psu used as an exhaust. Howeve once you raise the voltage and frequency it does start to heat up and can hit 55 @ 3.73

I find that hard to believe, probably the motherboard reading the temp wrong. While they do run cool they don't run at 33c (both cores?) at load in a micro ATX case and stock cooling.

I'm well aware AMD64's run cooler (hence the choice of chip for my main rig

), but I'm having no end of driver and setup trouble with my HTPC it's just made me totally sick of AMD, grrr!! I KNOW for a fact that Intel chipsets work perfectly first time with their first revision of drivers; superb design. So I'm sorta hoping I won't have to fanny about to get it working properly. I could go into what problems I'm having but that would take at least 3 or 4 different threads and I'm sure no-one will have answers.

I found the PERFECT mATX Pentium-M board (MSI 915GM-Speedster-FA4), but at over £150 I think that's a pipe dream for now! Maybe I should just try changing mobo... this ATi RS480 board just doesn't wanna play ball with me

2 instances of prime95 running both motherboard and cpu report the cpu temp as 35 degrees one each core. I'll post a screeny of it running now (although it has only gone through five tests)

don't know whether you can make it out, imageshack only lets 1MB files on it.

I dont think that you will manage to find an Intel chip that will run cooler than the AMD equivalent, thats a well known fact.

At the time I had a very powerful system which was a P3.2 all those years ago, and to an extent can still play good games today, but now if I was ever to spend on a new system or mega upgrade, it would have to be based around an AMD system, as they are cooler and more powerful

I'm well aware of that, my question was whether there were Intel chips that run coolER compared the rest of the LGA775 line

danceMB · 3 May 2006 at 11:21

I think the answer to that is a resounding no

OneWingedAngel · 3 May 2006 at 11:30

It may not be the coolest line, but the celerons 6x1 cedar mill series I would expect to be really cool, if I can get a dual core stable and running under 40 degrees i'm pretty sure the single cores will be nearer to the 30 degree mark and if you can undervolt the chip (my board lacks this feature) maybe even sub 30 with after market cooling. pentiums aren't that hot any more, still not cool though.

Yep any 6xx series has EIST + TM2 which both lower volts when the CPU is idle to reduce temps dynamically on the fly then when the CPU requires it raise the volts + temps again.

If you only want a HTPC either of these 2 below will be fast enough & cool enough.

Why not post your driver issues and maybe we can sort them? I have no problems at all with my htpc board an chip - MSI k8NGM2-FID + venice 3000+. I've not had one single crash or BSOD since building it and it goes weeks at a time without a reboot.

Going intel is going to be an expensive excercise, not only in terms, new hardware, heat and resulting cooling associated noise, but electricity bills too!

Chances are you'll go intel and find out it was your TV card or some other component giving you all the trouble!

Sumanji · 3 May 2006 at 13:03

The 805 actually looks pretty awesome (can't be that hot at stock speeds), but I don't think it supports EIST? And it probably won't work in i915P boards either

Excellent chip and they do run quite cool at stock, mine is at 3.65ghz and 1.45v yet only gets to 55c max with stock cooling (2500rpm, lowest speed) but you are right they don't work in the 915 chipset you will need either a Nvidia, VIA, 945, 955x or 975x for it to work.
