Heat woes solved!

[Vimeous]

A little while back I posted all sorts of troubles with my XP2200 TBred A running hot under my Akasa AK824cu cooler.
Well I'm pleased to say the solution has arrived in the form of a new XP2600 Barton (yes Barton). Temps have dropped to 58-59deg under full load. This was the same as the XP2200 when running an SLK-800 and evil-meanie 80mm Delta so I'm very pleased indeed.
Thanks to all those who passed advice my way on the previous thread

Oh and the cost of the solution? £70inc. VAT at dabs. Last time I looked Komplett also had them at £68inc. VAT. That makes it the most expensive processor I've ever bought but a bargain all the same

Are the Dies much larger on the Barton, or do they have some kind of heat spreader?? I have never actually seen one.

Or am i barking up the wrong tree... is it that they use a lower voltage?

[Vimeous]

Visually they're very similar on a basic level (no additional heat spreader). The main reason for the reduction in temperature is the smaller process used for manufacturing the chips. I believe the Barton uses a 0.13micron process and the TBred A 0.15 or 0.18 (can't remember). Others will know better. However smaller components generate less heat for a given processor speed, hence why the XP2600 is cooler than my old XP2200.

TbredA was made using 0.13micron process.

A comparision between TbredB, TbredA and Palomino.

Now there's a usefull link. Thanks for that Rod911!

Vimeous,

Could you give me your Multiplier,FSB and SPD settings please.

Also the 2600 Barton has a 512 cache with a bigger heatsink and fan and I think a Copper interface if that is the correct terminology.

What is your CPU fan speed ?

Mate this is still very hot for a slk-800 on top .

Ive got my clocked 2500+ clocked 3200+ speeds with a £17 heatsink and its getting 39deg idle and 44 full load on medium speed.

I'd have to agree with you there. However, temperature readings can be subjective. Just as long as the system is stable, it doesn't really matter what the temperature is.

[Stylez]

Yeh as long as the system is stable it doesn't really matter, if it becomes unstable then you'll have to start worrying.

as was discussed in Vimeous's last thread the room the computer in is a server room in his house (without aircon) - ambient temperature is at least 26°C which is the reason for the higher temps.

Another link I have that might be useful:

http://articles.cpuwars.com/k7s.shtml

It's in Russian, but the numbers are universal.

[Vimeous]

Yay mobile air-con!
The ambient temp in this room does tend to be quite high and it I also don't totally trust the numbers MBM5 is telling me as Sandra seems to suggest the temp is lower. However my machine was unstable at a quoted 66-67deg centi on MBM5 which prompted me to borrow the SLK and Delta. Now she's solid stable.

In terms of clock Vijay I'm running standard settings on my ASUS A7V8X mboard. With BIOS 1013 that means 11.5x at 333MHz. However I'm not exactly sure what's going on here.That should gives a clock of 1917MHz. In this aspect I need a little more help though. PCMark 2002 claims I'm running a "Missing CPU 1870MHz" which I have to put down to the program being old but even so the score isn't what I've been expecting. I got CPU: 5755 Mem: 4303 HDD: 714 which for memory is fine and the HDD is down to an older drive I'm about to replace. However the CPU score should be in the mid six thousands if some of the sites are to be believed.
Oh and the fan/hs I'm using? The Akasa is aluminium with a copper base and actually quite a bit larger than the SLK-800. The stock fan gives 32.37CFM at 2500rpm quoted for 25.85dB(A). It ain't silent but compared to the Delta it's an angel.

Another aside. I built an A7V8-X with XP1700B recently for a friend. With a single setting change from 133fsb to 166fsb under and Aero7 Lite cooler (running 1/2 rpm)it gave a PCMark 2002 of CPU: 6316 Mem: 3506 HDD: 269. That was running PC2700 mem and an old 8Gb drive with a supposed clock of "Missing CPU 2120 MHz" but at least that clock agreed with the BIOS!
