My just inserted Tbird...

[Erupter]

Ok... that's the problem: i've just bought a Tbird 1400 (266), but i can't make it run at 266.
I tried everything, but nothing worked.
The memory run fine ad 133, but the system together refuses to work at 133.
It posts, boots, starts, loads windows, and freeze randomly, but always when acceeding to an hdd.
This is my config, hope someone can help:
Tbird 1400 (266) (now at 13x100)
Abit KT7A-RAID
256mb ram PC133 (i'm sure it work at 133... it's doing so now, in asynchronus mode)
3 hdd on the raid controller (no raid arrays)
cd 52x on the southbridge
TNT2 (v3800) agp
Internal ISDN adapter (pci 3)
SB Live! Value (pci 4)
Water cooling (cpu temp is stable at 40°C)

 

[Erupter]

Ok i think temperature is the problem
26°C room (or at least mobo temp with case full open)
34°C chipset temp
40 (and more) cpu temp at 1333 (10x133)
So now it's running (apparentely) fine at 133 fsb...
But... i've watercooling with copper wb... how is it?
Don't think a standard HS cools so much, so, how much does this cpu heat??????

 

[McCarthy]

What power supply? Been reading about people needing 400watters these days, which seems funky to me, but what do I know. 40 at 1300 should still be in the low/mid 40's with another 100mhz, doesn't sound like a cooling boggle to me.

[Erupter]

I've a codegen 300w...
Anyway it's definetely a cooling prob
Maybe the wb is not pressed well on the socket...
Now it's 10min Genome is crunching and the cpu (1333 not 1400) is at 48°C....
Maybe this is the problem...

get a new fan

i am with you when you say that

check

here

or

here

 

[WildeBeast]

How are you setting the system bus to 133? Jumper I would hope, because otherwise you are trying to get all of your peripherals to run at 133/3 = 44 which is a bit above whjat they will take, usually. Maybe this has nothing to do with anything if you did change it with the jumpers.

 

[McCarthy]

New fan with watercooling might be a bit tough, suppose he could put a bigger one on the radiator though. 48 (even with variances in off die readings) doesn't seem all that extreme, lots of guys have been asking how to get their Tbirds cooled down when they're running 55-60, stable, but worried at those temps. You have tried double checking the waterblock contact, make sure that's all nice. Hope you get it figured out soon Can you up your water flow or get some more air to the radiator to get it cooler?

 

[Erupter]

PCI speed is not a problem, as i said, i've a KT7A which has the 133/33 setting.
The fan on the radiator is a sunon 12cm 4000rpm 69cfm, on a radiator you can see HERE
I know amd cpus run fine at temps higher then mine (my dead K7 700@900 ran at 50°C) but if it's not a temp prob... then what?
The cpu runs fine a 1333 10x133 so it's not a memory/bus problem...
The temp raises till 48/49°C under heavy load at 1333... i can only figure this is the matter...
I'll do some tests today...
Maybe a 156W pelt would put down to reason this cpu

 

[Erupter]

That's definetely not the best radiator on the market, but it is the best i can buy without a lot of money, and without a credit card...
Just for you credit card owners, another (better than mine i think) radiator is HERE.
About the water flow (i forgot in the last message) i'm now using a 800l/h pump, because i'm builidng the "in-case" system with the 1300l/h pump... so for now she's out of order

 

[Insane3D]

I really think your 300W PSU is not cutting it. AMD suggests a 400W minimum for the 1.4ghz Tbird. I haven't ever heard of that PSU and it's not a popular brand. I really think a nice Antec 400W or Enermax 431W is in order..

 

[Erupter]

You really think?
Because it would be a big matter...
Just for mobo,cpu,and cooling 500$ enriched another computer shop...
Now an enermax 431w is sold at about 105$... it's not that cheap...
Maybe in the future, because now i'm quite pennyless

 

[Scouzer]

1) Your TNT 2 is going to slaughter that system if you do get it working right
2) 350w decent brand should be more than enough
3) Make sure the PCI/AGP etc divider is set to its respective amount as compared to 100fsb

 

[Insane3D]

Well, an Antec 400W can be had for around ~$70 and the Enermax for ~$80. I would try to underclock your CPU a bit, and try to reduce some of the power draw from your PSU. For instance, maybe you could only use one hard drive for awhile, and this might allow enough power to get to the CPU. Also, I am not sure if your water cooling setup uses your PSU or not, but if it does, a good HSF will keep things pretty cool. Sorry, but I really do think it's your PSU holding you back..

 

[Erupter]

That my tnt2 is less than and old handwriter makeing calculations, i already know... but my cpu/mobo died 2 weeks ago, and all the money had to be spent on the new system...
The pci is set correctly (i'm running 133/33 x 10 = 1333).
About other brands... well in italy the market is quite different then in USA or other countries:
people is stupid, the most doesn't update drivers or bios, doesn't understand how computer works, and thrust names like Vobis or Computer Discount... which are not extactly like Dell or others...
So the mainstream market imports only no-brand products (and this is true particularly for the memory modules), and the good products are privately imported by a few shops, which don't compete on prices...
So 350W psus doesn't exsist here, i could only buy an Enermax or a codegen...

 

[Erupter]

Insane 3D, the prices I reported, are the prices i can buy the products, converted in dollars...
For the psu... i can try this: i've the old 250w psu, i could use it for the hdds and the cdrom, and leave the 300w to drive the mobo/cpu...
This should reveal if the psu is the problem...
The watercooling isn't powered by the psu, except for the sunon fan...

 

[Insane3D]

Yeah, give that a try. It's not really that the PSU can't power all the things in your system, it's just that the 1.4ghz Athlon draws a lot of power, and most 300W PSU's have trouble feeding it a constant, and steady flow of current. I would highly suggest you try to save up some money for awhile and get a Enermax. Not only will it be more than enough for what you have, it should last you a long time and handle the power draw of newer CPU's down the line.. Good luck..

 

[Erupter]

I'll give it a try later...
Hope it will work...

My friend has Tbird 1.3 and his PC runs 50C under no load and 58-59C with load, he uses a thermo engine, I think it's pushing it, my AMD is a Tbird 900 and it still heats up my room with 49-50C under load.

 

[formulav8]

I can run my bird at 1.5ghz on a cheapo 300w ps with no probem.

 

[AvidOC]

Yea i reckon PS, get a enermax 431W if i were you

 

[Remnant2]

Insane3d: Where did you hear that from?

According to AMD's own website here, many 300w power supplies have been tested and approved for use on the 1.4ghz Athlon.

 

[Insane3D]

I guess I was mistaken, but I am pretty sure when they first released the 1.4ghz, it was suggested to run a 400W model. In a system with several peripherals like 3 hard drives, it might be too much for a regular 300W PSU. Also, having had some conversations with Compuwiz1, he remarked that all the new 1.4ghz's that he is doing overclocking tests on would barely o/c at all with 300W Sparkle PSU's that he was using. He had to switch to a 431W Enermax to get the most from the 1.4ghz chips. There are also several sites reporting getting higher speeds from the new stepping Athlon's when switching to a higher wattage PSU. If only mildly overclocking a 1.4ghz is starting to require a higher than 300W PSU, than that makes me think a 1.4ghz Athlons current draw is right near the max capabilities of a 300W PSU. There are always some situations where it will work fine, but it never hurts to have a slightly larger PSU than needed to ensure a steady current to the CPU. Also, the power regulating components of motherboards can have different tolerances between manufacturer's and it might work on one board with higher quality components where another might not handle it. He is using the KT7A, which has been shown lately to limit o/c speeds on some chips...could be some lower quality power components being used..or not. I just feel that a 400W PSU is a good PSU to have if you are running 1.4ghz+. If that one component can't handle the power draw, it will make everything else in the system suffer. Also, the PSU make he mentioned is not one I have heard of, and a lower quality 300W has even less chance of cutting the mustard...so to speak. I think we can agree that a 300W Enermax or Antec is not the same a generic 300w PSU in terms of delivering reliable current on the various rails...

 

[Tuan Nguyen]

It's neither the PS, nor heat or anything else that is the problem.

The problem is your current multiplier is set too high for 133MHz FSB operation. Currently you're set at 13x100 correct? When you switch to 133, it's 13x133... way too high to operate.

Turn down the multiplier to a very low setting, like say 7x, then set the FSB speed to 133MHz. Now reboot. It'll turn on and then once you're in the BIOS again, just set the approriate mutliplier to give you 1.4GHz at 133MHz FSB setting.

 

[Insane3D]

"The cpu runs fine a 1333 10x133 so it's not a memory/bus problem"

I don't think the multiplier is his problem. He obviously knows how to change it correctly..

 

[Tuan Nguyen]

Right but he has it at 13X and then tries to run it - leaving it at 13X - at 133FSB... giving him 13x133 = 1729MHz. Much too high.

He can set it at 10x133 because it's a 10x not a 13x.

Because he's trying to maximize his settings to achieve close to but not 1.4GHz, he's using a high multiplier, then forgetting that trying to get 133MHz without first booting with a lower multiplier won't get him very far.

I know he can change multipliers. But I'm saying it seems like he forgot to lower the 13x back down before jumping from 100MHz to 133MHz FSB.
