Jumper settings questions

[vcd4me]

help

I just built a computer recently and have been having problems with it. Thanks to northcat_8 I have resolved some but as he was helping me he had me look at some settings so I investigated some more and I noticed thatv If I look at my systems properties it says:

Athalon amd 1900+
1.47 ghz.
448 MB of Ram

Now I have heard that the 1900+ is just a rating that amd uses and the 1.47 should be the actual speed in this instance. However the thing is, my cpu is actually a 2500+ amd

Here are the specs of my computer

mach speed vb4mdmp http://www.machspeed.com/ve_v4mdmp.htm
Amd 2500+ barton core(333mhz)
512 pc2700 ddr 333mhz

The board is supposed to be jumperless . I however went to their site to find out why it was only reading 1900+ and that is wher I get lost.

If I goto the knowledge base secction of the site
I find this
>My CPU speed is incorrect?
Solution for Socket A Boards: Unplug the ATX power connector from the MB. Check your FSB Jumper to see if it is set correctly (refer to table below).
Athlon XP 2500+ JP4 3/4
Go ahead and plug your ATX power cable back into the MB and turn the machine on.

I did this and in the self test when my computer turns on the 333fsb but the 1900+ stays the same in the system properties

Now if I goto cpu support lis and look for 2500.I find this


Athlon (0.13u) AXDAxxxxDKV4D/1.65V 512K
CPU FSB RATIO RESULTS
AthlonXP 2500+ 166 11 OK
but it is for bios version A01 and mine A04 I think?

So here are my questions

1 If I change the ratio jumper to be 11x I would have to have all the jumpers on acording too the MB book (again the jumpers are on 3 and 4 now ). would this change the 1900+ reading to a 2500 and still have the reading be 333fsb. I am confused because in the instruction book it says to put the jp7 jumper on too make it be 166mhZ.

2. If the computerv is only reading
Athalon amd 1900+
1.47 ghz.
448 MB of Ram
in the systems properties does this mean its only running at the 1900+

The reasaon I ask is someone on this site once told me that if my computer was only reading 256mb ram (even though it was actually 512) thjat it was really only using 256.

Thanks in advancce

That's true. If you have 512 installed and it's only reading 256, then the RAM stick is not seated properly, the stick is bad, or one of the slots is bad.

Yes, make the changes that they tell you. Then in the BIOS, I think you need to adjust some settings, mine are under the "advanced" menu...but you are looking for your processor speed setting. Somewhere near there, you'll have a frequency and a multiplier it will look something like "133/13.5" or something like that. To go with the higher processor speed you will need to change that to be "166/12.5" or "166/13". These are to run your processor at 2.1 Ghz. You can play with it and run your processor at whatever speed you want. Barton's are notorious for being overclock friendly, so you can run it up there a good ways "166/15" would put you at 2.5 Ghz. You may have to select a "user defined" processor speed in order to access these settings...that depends on your BIOS and of course all of this is dependant on CPU stablity. Watch your CPU and MoBo temperatures.

I do not think however that your FSB can exceed the speed of your RAM...I'm not 100% on that but I believe that to be a fact. So you may have to speed up your ram, if it does not run at 333.

AMD is typically 400 less than the processor name. So a 2.2 Ghz would run at 1.8 Ghz.

Check out www.ocforum.com, it is an overclocker forum, but they break it down by mother board. Folk over there know all the technical terms for everything and would be able to explain it more accurately. I maybe WAY off base here...I don't think so, but could be.

I would make sure you have the most recent BIOS installed first though, as just installing it may solve the problem. Depending on how old the board is, the defaults maybe set with the most common processor at that time and your 2500 Barton may not be fully supported, so the Barton is just running at BIOS default or a maximum set on past standards...if you know what I'm trying to say there

northcat,

Thanks for following me around and helping out...LOL

So I did what the book siad put all the jumpers to make it be 11x. I went to the bios and I can't find anything to change.

The computer reads correctly in system settings

some more questions

1. Now that the computer is reading correctly does this mean it is running faster?

2. The book says 166mhz x 11 . well if I am figuring this out correctly that means 166x11= 1826, you mentioned 12x and 13.5x so At what point is it considering it overclocking?I heard overclocking can be bad for a system/cpu

3.WHile looking in the bios I noticed this" video ram cacheable disabled"
What exactly does that do/mean.

4. Could this be my video problem in IC .

As always THANKS

Not really following you around...I'm pretty much a insomniac.

like I said, you will find more accurate answers at ocforum.com

Check what cpu-z says about your specifics as far as CPU speed and FSB. If you don't have it, you can download it at www.cpuid.com, I think I already gave you the link but just incase.

I would have to know more about your BIOS to be able to tell you where to find it.

The point it is considered overclocking? I don't know. The danger in OCing, is with the CPU and MoBo temperatures. As long as the system is stable and the temperatures are ok, it will be ok.

3.WHile looking in the bios I noticed this" video ram cacheable disabled"
What exactly does that do/mean.

That is asking you if you want the PC to use your video card's ram as a cache....you don't, and it won't fix your problem with IC.

I wrote an overclocking guide with beginners in mind. I'm going to expand it in a few weeks once I get back to uni (can't change it remotely). Here's the link - post your comments if you like!

cobra,

Nice guide !

right now my system reads
2500+amd
1826Mhz.

When exactly is it considered overclocking ?
Am I already overclocking or was my system just not set right ?

Thanks in advance
Ed

An AMD 2500+ processor actually runs at 1.83 GHz, or 1826 MHz.

Overclocking is considered anything above the 'posted' speed. So if you moved it up just 1 MHz, you'd technically be overclocking.

If your computer shows it's running at 1826 MHz you are now at the posted speed limit.

Ok great I really don't want to overclock

I just wanted it to be running at the correct speed that I paid for...

Thanks
