Bad CPU? My Athlon XP 1600+ only works up to 1.1GHz :(

[LukFilm]

Hi guys!
I was putting a new CPU in my motherboard and for the longest time I couldn't figure out why it wasn't booting. All fans were on, but nothing on the monitor. Then I decided to put it on 100MHz FSB and voila! It worked. However, that's only at 1050MHz. When I try a regular 133MHzx10.5, it doesn't boot. What's the problem? CPU? Motherboard? Power supply? I have Soltek SL-75DRV2.

What kind of PSU and what kind of memory?

Write up the list of components LukFilm.

maybe its me or i am stupid but my athlon 1.4 runs 10.5 @ 133 =1396.5

but it wasnt that easy for me heres what i did

tryed to set jumpers to 133 no video output

set to 140 fsb see cpu @ 1470 still wrong

right my MB is now set to 140 then in bios i set it to 133 saved bios then shut down moved jumpers back to 133 and started pc worked a charm but i have a gigabyte GA-7VTX so i dont know what your MB is like but this is what i had to do

so i say to you that your bios / jumpers are set wrong or like me your bios has a setting called "BY JUMPER" for fsb setting if not forgive my ignorance and i appologise for this post

i am just posting my experience in setting my 1.4 up hope it all helps

regards

Do you have decent cooling? What about your ram, are they pc2100 (try to low it to conservative setting IE 2.5cas, 2t command)

 

[ScrapSilicon]

boot it up on the 100bus ...go into the BIOS...do "Load Default Settings" then reboot then go into the BIOS check the factory settings/write them down (why am I telling you this...you should know all this chief ) Shutdown ...move the jumper then boot ..report back..please

 

[Budman]

You need a better power supply,350watts+ that's AMD aproved for your 1600+.

 

[LukFilm]

ScrapSilicon, I'd love to do that; however, as I posted, I cannot boot when the FSB is set to 133MHz.
Budman, I don't think it's the power supply as I had a regular 1.4GHz T-Bird running on it just fine...

Raise the DDR and CPU core voltage. Try a new BIOS.

 

[LukFilm]

DDR and CPU voltage were raised, there is no newer BIOS... :|

 

[Catchen22]

Maybe it's your mobo? I would of suggested a better power supply too but you said it's working fine.

If it supports a 1.4 ghz athlon jsut fine then it isnt the power supply. only thing left is the MB.

try setting your ddr timing to 2.5 or 3 ns
you list your ram as cas 2 pc2100.

 

[LukFilm]

I tried that too. I'll stick the CPU into an ECS K7S5A and if it works there, back to Newegg the motherboard goes...

and the cpu works fine in your ecs board?

 

[nortexoid]

clear the cmos, set the multipleir by jumpers if possible...if not, set it at 100, boot, then set it at something other than 133 and boot (i.e. something near 133)..if that works, something's wrong...make sure your memory timings are on fail safe...load the fail safe bios settings to be sure.

 

[BurnItDwn]

You may or not have tried this, Try raising the Latency of the ram, and then booting at 133. That may fix part of the problem

Bull.

I have my 1600+ OC'ed to 1900+ on the same board, and all of this is running off of a 235W supply.

And no, there aren't any stability issues.

 

[RanDum72]

That is one high performance 235 watter! But its usually good to be on the safe side and have at least a 300w PSU. There is no denying the fact that problems do arise with systems that have crappy PSU's. But in this case, the mobo may be to blame.

 

[mrman3k]

I would like to ask a very simple question, how does the power supply effect the performance and settings of the CPU, as I understand things the PSU simply supplies power to the MB, unless things have changed about the way computers operate I am sure the PS has nothing to do with this problem. Instead try replacing either the motherboard or CPU.

 

[RanDum72]

The PSU provides power to the mobo and the CPU. A CPU at 1.4ghz draws more power than a 1ghz CPU, plain and simple. The way the PSU provides power will also affect stability, the more stable the current (less ripple), the better. A PSU pushed to the limits will be less reliable in its power delivery and may even fail.

 

[LukFilm]

True, but as I pointed out, I had a regular 1.4GHz T-Bird in it which draws MORE power than 1.4GHz Palomino T-Bird, correct? So, the PSU should not be a problem. I'll test out the CPU on the ECS mobo today and report back my findings...

 

[SammyBoy]

let us know...

Sounds like your MB don't support XP's. I had the same issue with the Abit KG7 I built for a customer. But once I flashed the bios it was fine. So either contact the mb manufacturer and see if they have a new bios out or coming out soon or get a board you know supports XP processors like any of the 266a motherboards out there. The Epox 266a board can be had for like 98 dollars on newegg.
