clock speed

so my desktop chip is *supposed* to be an amd 1400. i say it like that because i have to set it in the bios as 1050. when i set it at 1400 it locks up every 5 minutes. is there a way i can tell for sure?

now, i got this thing second hand, so i am second guessing it i guess.

also, while i'm asking questions...

is there a way to tell which motherboard i have? i think its from SiS

Somewhere on the motherboard will usually have a printed model number.
Go to SiS' website to see the model numbers so you have an idea of what
to look for.

Funny that you should mention this...
I got an ASUS A7S333 a few months ago. It crashed constantly during compiles the first day, then just plain froze after ten minutes after that. This was, of course, if you ran the chip at its intended 1500 MHz- if you ran it at 1150, it crashed less, but was still unbearable. I call ASUS, and they told me that the board was very particular about what type of RAM it would cooperate with. They gave me a list of only three manufacturers that I should purchase RAM from. I went out and bought some Samsung RAM, and I haven't had a problem since.

i dont know if it is related. but promptly after i got the thing, i tried to install windows xp (its for my wife. chill out.) but it kept hanging on the install. i tried every version of windows i could get my hands on, 2k, me, 98. none would finish.
i finally figured out that something had gone wrong with my ram. i went out and bought a new chip and walla! it installed fine.
now that you say that though, i wonder if it could have fried my ram because it was running at 1400 then. if i can ever figure out what kind of mobo i have, i'll have to check that out.

If the processor is truly rated for '1400', it shouldn't be an issue. I have heard some time ago
that some CPU's were being overclocked and resold as a higher MHz CPU. Don't most CPU's
have their rating on them from the MFG?

A side note, just in case...

The AMD Athlon XP processors are identified by numbers, e.g. Athlon XP1800, but these numbers aren't the actual clock speed they run at. The Athlon XP1800 model runs at 1500 MHz.

I didn't think you could "fry" your ram by running the processor too high?

I thought the bus speed was the determining factor?

if you wanna know stuff bout your cpu (including speed)

abhishek · Posted: Thu Jul 11, 2002 3:09 am Post subject:

U can get theprocessor fastre by increasoing the bus speed(which i guess can fry the ram) or increasing clock multioplier(only affects cpu)

abhishek · Posted: Thu Jul 11, 2002 3:11 am Post subject:

Also most processors have the clock multipliers locked(intel=unlockable, amd unlockable b something u do to the chip), so most times when the cpu speed is increased its done by bus speed

AMD 's chip's arnt sold by actual MHZ they're sold by a performance rating,so if you've been sold an 1400+ processor , this indicates the cpu will perform comparable to a p3 1400 or similar but the actual clock speed will be lower .....

Cheers

Oddly enough I have that exact same issue on my box. The chip was bought before AMD released their "+" ratings, so the rating is correct (unless I got a bad one), but the system runs unstably at above 1.1G. It's also mega-unstable at 133MHz FSB at any speed, so I'm running at 100MHz with 11X multiplier, and blaming the cheapo generic brand RAM for the problem.

I thought for a while it could have been the cooling (my home-built boxes tend to be hit-or-miss in that dept), but even at higher clocks the CPU temperature was remaining under 50deg C, and presumably not melting at that.

Just occurred to me... I've never had to tell my BIOS what the MHz of my system were.

You haven't used AMD recently, have you?

I had the same problems but with a different motherboard. It is most likely memory timing.

First update the BIOS for your motherboard.
Then adjust Chipset Driving Control
Disable Super Bypass Mode
Set your memory CAS latence to 2.5

I'm guessing it's an athlon.

What sort?

I don't think durons have got that fast yet.
And I thought AthlonXP started at 1500.
Laptop, something makes me think there was a 1400 for laptops, or something...
Of course, I could be completely wrong.

Either way, I'd guess a 1400 to be around 1.1 - 1.2ghz.

Note to self, NEVER post before coffee again...

It's a 1.4GHz Athlon Thunderbird that you're running at 10.5 x 100 rather than 10.5 x 133 that you should be running at (it's a 133MHz CPU).

Sound like either you can't keep it cool enough or there is some component in your system that doesn't like the higher front side bus speed.

I'ved the same problem on my A7S333 board,
but new RAM (Samsung) and

I have a asus a7v333 and a athlon-xp 2000+ (1667Mhz) and it runs very stable 256Mb pc2700 CL2.5 kingston memory (note however that you need to set the DDRAM setting correctly in bios, if you use TURBO as performance option and you have CL 2.5 memory you shouldn't use SPD settings, but override them)....... Never had any problems on any computer with memory, but maybe I'm just lucky.....

i have always had AMDs, but my k7-550mhz had a whole bunch of problems with stability. After my first boot i had to do a reset before everything went stable... never figured out why. (ohyeah, acpi is really evil with amd's)

now i have a p4 and it is _really_ stable ! (the only thing is that the bogomips are a bit lower then i expected, always thought that bogomips=2xcpu)

Athlon-tbirds are sold at their actual MHz value. A tbird-1400 runs at 1400 MHz. They only do that silly fake-MHz nonsense with XP's and MP's. (thoroughbreds out yet? I'm not up to date on the news)

I'd put my money on faulty RAM, possibly your MB or video card. A bios flash probably wouldn't hurt.

The only problem I had with my athlon-tbird 1200Mhz (133Mhz) was that the voltregulator of the motherboard blew up just after the warranty expired, the system however ran very very very stable (all my systems have) and I used and am still using ACPI but both motherboard had VIA chips. I have a 300+ power supply etc......, unstable system can have many causes, overheating being one of the common ones, bad hardware another and variation in voltage another one,....

Well that silly Mhz thing as you probably know is because you should measure the power of a CPU not only by it's raw klokfrequency but by it's raw power, and well test clearly show that at the time, it was the right thing to do regarding the competion with Intel...

Ps. I settle for a lower klokfrequency and higher performance,
