tualatin celeron heat

[Chris1992]

how hot des one of these run? i have 1200mhz one unstable on trigem lomita board. may be heat?

Re: tualatin celeron heat

Doubtful.. Tualitin Celerons are quite cool running. Not quite cool enough to run with only a passive heatsink, unless you perhaps underclocked it. I know only certain chipsets had "real" support for Tualitin core chips, had to have a certain stepping of the i815 chipset for example. Via had the Apollo 694T. Also the board should have VRM 8.5 support, otherwise you'll be overvolting the I/O buffers of the CPU. It should work OK though even with VRM 8.4, but the CPU life may be shortened.

Re: tualatin celeron heat

IIRC the board is 810e, not OC'd, IDK about VRM8.5 support. Sorry for the bad capitalisation in previous post, I was typing with OSK on aforementioned Tualeron box b/c it wouldn't recognise the kbd.

Re: tualatin celeron heat

Oh, i forgot one chipset. The via 8601T also supports tualitin.. I've got a gently overclocked Tualitin 1.2Ghz on a 8601T motherboard, an i don't think it's ever hit 50C ,with a stock intel heatsink, even running Prime95. Tualitin's were the peak of the P3 architecture, until the Pentium M came around.

Re: tualatin celeron heat

Late steppings of the i810e and i815e, and various Via chipsets support the Tualatin. The VRM also has to support the lower Vcore (~1.475) as well as the higher current requirements of the Tualatin. If you do get a motherboard that supports the Tualatin Celeron, it's a great performer and very reliable. Many 1.2GHz Tualerons will easily overclock to 133 x 12 = 1.6 GHz with very slight overvoltage.

My own benchmarks show the 1.2 GHz Tualeron with PC100 SDRAM to be a solid 25% quicker on compiles under Linux than a Northwood 2.6 Ghz Celeron with DDR - the 256k L2 cache on the Tualeron has lower latency than the 128k L2 on the Northwood.

The performance, reliability, relatively low power consumption, and overall robustness and maturity of the platform make the Tualatin the high watermark of all Intel desktop CPUs. Use a Slot-T adapter and plug it into an i440BX - there's nothing comparable, clock-for-clock. Well, Athlon-XPs, Sempron-64 and Athlon-64s are faster, but they're also more expensive and power hungry. For HTPCs, the Tualeron is the best value. Yonah, Merom or Conroe may eventually surpass it in 3 or 4 years, but for now, there isn't anything comparable.

i confess to running a piii 866 with stock heatsink for 2 days without fan during install . now in production and no probs.

anyway check if heatsink is flat on the proc with nice thin layer of TIM, fan is working and then you can eliminate heat as an issue.

need more info though on this instability. run some memtest86 to see what ram is doing.

Re: tualatin celeron heat

The fan (6x1cm) is working, will check for TIM and prob. clean and apply AS5.

Re: tualatin celeron heat

i ran into a tualeron in a mitek cybersaw control head that had a dead fan.
the maintainence guy said he had never seen that fan run.this unit is a sealed box on an arm that moves with the machine.it is sealed so sawdust doent get in.
the problem turned out to be the media converter from fiber to the ge-fanuc ethernet module.
it got a new fan anyway.

Re: tualatin celeron heat

Even as an AMD guy, I agree with linuxguru...The tualatin celeron is a great processor.

Re: tualatin celeron heat

Actually, I'm a mixed AMD/Intel guy - but I skipped the P4 line almost completely, except for a freebie Northwood Celeron 2.6 GHz that was left over after I upgraded a friend's Dell Inspiron 1150 with a Northwood mobile P4 2.66 GHz. The Celeron 2.6 works in a stock Intel D845PESV board, and it's my main desktop - perfectly reliable for day-to-day use, but not as quick as a Tualatin or Athlon XP at half the clock speed.

I have AMD CPUs dating back to the 80C286/12. However, the 32-bit Athlon generation has generally been more finicky because of heat and power issues than the equivalent Intel platforms. I've been able to work around the issues by using AS3 TIM, careful polishing of heat-sinks, recapped motherboards, and recapped PSUs, but the average Joe is likely to have seen the Athlons as unreliable.

Thankfully, that's all changed with the K8. However, there's a new set of issues relating to the numerous Socket alternatives and longevity of each platform. Each socket is being EOled just as it reaches maturity - for instance, Socket-754 has gone. It's still one of the best budget platforms with a Sempron-64, but there's no clear upgrade path left for it now. The Socket-939 Opterons are on their way out - and those were among the best enthusiast CPUs around.

I just wish that AMD settles on a single, standard socket that can accept everything from a Sempron to an Opteron. Socket-370 was close to that golden mean for Intel/Via.

Re: tualatin celeron heat

Mixed bag, same here, Intel 286, AMD 386DX 40, Intel P166MMX, 233MMX, K6-2-300, K6-2-500, Duron 950, P3-733 (IBM machine), XP2200+, & Winchester 3500+ waiting for a new home...Typing this on a GX260 (P4)...Even have a National Geode touchscreen, transmeta embedded, IBM 686...

32 bit Athlons, aka socket A had a good 5 year run... Hottest was the XP 2100+ (Palomino) & XP3200+ at ~ 72-77W Max Theoretical Thermal output...

Socket 754 can be had for a bargain now, I just priced an upgrade:

BIOSTAR GEFORCE 6100-M7 Socket 754 NVIDIA GeForce 6100 Micro ATX AMD Motherboard $59.99

GeIL Value 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered Dual Channel Kit System Memory Model GE1GB3200BDC - Retail $82.55

AMD Sempron 64 2500+ Palermo 800MHz FSB Socket 754 Processor Model SDA2500BXBOX - Retail $66.00

Subtotal: $208.54 before tax and shipping...


All sorts of stuff!

Re: tualatin celeron heat

AMD Sempron 64 2500+ Palermo 800MHz FSB Socket 754 Processor Model SDA2500BXBOX - Retail $66.00



Awesome chip here... I've got one myself. It's the lowest speed grade Sempron 64 that has 256K L2 cache. Quite a little screamer when overclocked, and runs practically as cool as the Tualitin P3/Celeron. I've got my S64/2500+ overclocked to 1.93Ghz, with a +0.1Vcore bump.. Could probably do more with more Vcore, but i usually don't give chips more than 0.1V more than the max Vcore that the manufacturer set them for.

Re: tualatin celeron heat

I was mistaken about the S939 Opterons being on the way out - they're still around, but AMD has bumped up the prices on most speed grades. For instance, the Opteron 165 has gone up in price from $295 to $325, etc.

http://www.theinquirer.net/?article=29095

The Palermo is available only in a combo bundle locally - and the motherboard is one of the commodity ones which I'll have to recap if I buy it. It goes for ~$120 for the Sempron/2500+ w/motherboard, and that's about $10 higher than 3 months ago. I'll probably bite the bullet, get it and recap it immediately, warranty be damned.

Re: tualatin celeron heat

Well, I did some work on the tualeron eMachine, replaced the PSU. It works fine now with a replaced PSU and a PS/2 kbd instead of USB. It survived a weekend of Prime95.
