T-Bird 1.33 Problems

[K-man]

Has anyone had a chance to play with these chips yet??

A Customer has brought one to me that has a slight problem.

It idles at 47Degrees Celsius. If we install an OS and boot to it, it idles at 56Degrees, and for some reason, when we run a game, it will boot us from the game, and the reading that we get is around 76Degrees.

We have tried 3 Different AMD "Certified" coolers, as well as The Core by CPUfx. so far, all of them have given the same results. We thought it was the chip, so we swapped the chip. Same thing. Tried the MoBo, and had the same problem...

I'm at a loss, does anyone have any ideas?

Full System Spec:

AMD T-Bird 1.33 (266fsb)
256Mb ECC DDR Ram (This is registering as NON-DDR, but ASUS says the board doesn't recognize it right)
ASUS A7M266 MoBo
Hercules 64Mb Graphics
SB Live Platinum
Adaptec SCSI Card
DVD
CD (SCSI)
CDRW (SCSI)
30Gb Hard Drive
60Gb Hard Drive (Yes 2)
Floppy Drive
ZIP Drive

A FULL ATX tower, with a Redundant Cooled 300w Powersupply (This is
only a redundant COOLING ps, not a redundant power, power supply).

Thanks!

I just got one of the new AYHJA stepping 1.33 266 T-birds. It is idling at 50 and bumps up to 53 playing Q3. I'm using a Global Win WBK38 with a Sunon fan on it (it is much quieter than the Delta that comes with it. My MOBO temp is 33 at ilde and stays there when I play Q3. I have 2 case fans and the PS has dual fans in it. There are a total of 7 fans in the box. This may sound like overkill, but it seems to work. Your problem sounds like heat. The so-called certified HSFs won't cut it with a hot chip like the 1.33.

P.S. Did you put heatsink compound like Arctic Silver on the chip???

We're using regular grease that comes with the fans. The Core came with a tube of it, and we've been using that.

However, if yours is stable at 53, maybe its normal for this cpu, and the lockups are another issue all together.

I'm sending the system home with the guy on monday. I told him to look into a better cooler than the Core that he is using, and also get some arctic silver if he absolutely needs it to be cool. The motherboard he is using leaves very little for overclocking via multiplier etc...

I'm trying to sell him a board we have that lets him overclock in 1mhz incriments. on this board, I haven't had any "Lock" problems....

My T-Bird was at 52C idle with AMD recommended cooler. Coolermaster ep5 1i11 I think. I now use a MC 462 with Delta fan and some case mods and is idling at 30C and 35C with load. If he wants to overclock he should look at better HSF and case cooling. Maybe the new Glaciator will work. Oh yes I also used artic silver. The T-Bird gets pretty hot with average HSF's. My locking problems was mostle because of FSB overclocking and/or memory settings like CAS. I'm using FIC AD11 mobo, which works well, but becomes unstable once I go over 138Mhz FSB.

I have a 1.333 in a KT7a-RAID with a Global Win fop-32 with AS2 on it and 2 Sunon 120mm case fans. I idle at 40C and load at 48C. I found a big difference in temps when I moved the case fans. Having a case fan blowing at the processor cooler will do wonders. Check out Hoot's article on "cohesive air" on the home page, in the article he has a diagram that shows how a HSF recycles the heated air.

Hmm. After reading the news for today, looks like AMD might have known about this heat thing...

The chips I am using are all AXIA stepping chips. Not sure if the newer chips are any better in the long run, but they do show lower temps.

One of the cheapest cooling solutions I've seen for this is the ThermalTake Volcano 2 or 3 with the stock fan removed and a 7000 rpm delta in its place. The volcano is a very well designed heatsink, however, the stock fan on these are not very effective. Give it a try!

KMAN- i think its defianately HEAT that is not getting absorbed via the HS.

1. Dont use stock thermal grease on a high end chip like that. Go for AS2 (artic silver 2)

2. Most AMD approved HS are not really capable of ahndaling the heat that these chips produce-u need a overclockers HS- like a Good Artic of a FOP with a good fan

3. That is hot for a chip and 76c is near killing it-even though they say 90c is the max.

Get a beter HS -lap it with 800-1200grit sandpaper, athen use AS2. I promise the chip will b more stable-also try adding maybe another exhauset fan to get rid of excess hot air. Hope This helps

Thanks. I'll definately try that out.

The only problem I see with this, un-benounced to me, my "Salesman" sold 3 cpu's this week with generic hsf's, and all three are in with heat problems. I am going to print this forum out to try and convince them to eat the cost of better hsf's. And arctic silver 2 grease.

Thanks again.
