CPU upgrade for a Presario 722EA

I have a Presario 722EA, and after changing the slow HD with a faster Seagate Momentus (40 GB 5400 rpm 8 MB cache) and adding another 256 MB RAM, I'd like to switch from the actual Mobile Duron 1100 (35W) to a faster CPU.
How high can I go? What's the fastest CPU I can put in it?
I have already checked, obviously, and the CPU is in standard socket A format, so it's easily upgradeable.

I know for sure that an Athlon XP 1700+, Thoroughbred A core, 133 MHz FSB would work, but I'd like something better, if possible.

Has anyone already tried upgrading the CPU on a Presario of the same series (Presario 7xx)?

Thanks in advance.

This one is 1.8 ghz, probably around 2500+ or so, not bad at all.

Thanks you very much, but:
1) that's not a Mobile CPU. However that's not a big problem, since I could mod it to Mobile playing with the L bridges
2) how can I be sure it will run in my Presario 700? My difficulty is not in finding a CPU, but finding a CPU that will surely work.
3) what's the power consumption of that CPU?

Please help me if you can.
Thanks again.

I'm pretty sure that Mobile means more than some foobing L bridge. Else they wouldn't be such overclockers favourites

 

No, really, the only difference between a mobile CPU and a desktop CPU (at least if we talk about AMD socket A CPUs) is in the bridges settings. Have a look at the various overclocking sites and you'll see I'm not wrong.

About overclocking I can say that they overclock very well just because those are CPUs selected to work stably with VCOREs much lower than those on the desktop versions (ie 1,35v on the mobile version versus 1,65v on the desktop version). So setting the vcore to the standard desktop CPU vcore (that is 1,35v@1,65v) will give much room for increasing the frequency.

My questions still remain the same.

At least can someone tell me where to find the technical support phone number?

they are good overclockers mainly becuase there multipliers are unlocked for varying clock frequencies. This is why there so favoured.

 

I have a mobile barton xp2200 133fsb in my desktop oc to 2.1gig 1.65vcore 200fsb(2.4gig 1.875vcore max). Excellent value 6 month ago $85. The mobile amd are normally 1.35-1.45vcore 35-45 watts. One of these will probably work as long as the laptop can dissipate the heat and the bios supports the multipler and voltage. On the newer amd chips have a laminated chip so you cant change the bridges but my nforce mb unlocks the multipliers.

Presario 700 have no jumper (just checked, as I've had to change the CMOS battery), but you can change the FSB via software (along with memory frequency and timings and other less interesting stuff).
However I won't tell you how until you post your Mobile 2400+ codes.

 

I have a Presario 723RSH. It originally came with a Duron 1.0ghz. I put an Athlon 2400+ XP-M in it. It runs fine but the fsb is still at 100mhz. Do the presarios have a jumper for the fsb?

Thanks.

 

Mobile 2400+ codes?

 

Yes, that is what you read on the CPU.

 

Look at this photograph:

This is an Athlon 2800+. Just tell me what you read in the black rectangle of your Athlon 2400+ XP-M

Thanks.

 

Thank you very much. There's a software that can edit some parameters of the chipset in our laptop systems. Among others the FSB and dividers can be set to 66, 100 or 133 MHz.
To be honest 66 MHz seems quite strange to me on this chipset, but if the nForce2 Ultra400 mobo in my desktop system can run at 66 MHz maybe the KM133 can, too, since it's much older
I forget the name at the moment, I'll post it as soon as I can. I still have it on my laptop, but I'm away from home and posting from another PC.
Stay tuned.
Thanks again.

Ok, your CPU is a Mobile Athlon 2400+, the low voltage 35w version, running at 1800 Mhz and 1,35v.
Since it's a Barton it has a 512 KB L2 cache and according to the first line it should be running at 266 MHz FSB.

The program I used was WPCREDIT (this makes temporary changes to the chipset, to make them permanent use WPCRSET, instead, and BE CAREFUL! It can be DANGEROUS!).
Coupled with the KX133 .PCR file (search the net for "11060391.PCR") it can set a different FSB or memory frequency (but also timings and other stuff concerning AGP and the rest of the system).
I have successfully set the memory frequency to 100 MHz instead of 133, just to try if the program works. Well, it works!
I haven't tried to change the FSB, but the procedure is almost identical to that of the memory.
All the necessary files can be downloaded from www.overclockers.com, together with a step by step guide.

Let me know if it works for you.

WPCredit doesn't let me change the fsb. I tried the KT133 and the KX133 pcr's. For both the fsb setting is in offset 68, but I can't change any of the numbers in this offset.

 

Hi, I'm know this is a somewhat older forum but I could use some help. I have a compaq presario 700 with a duron 900mhz. I'm more of a beginner with laptop hardware though have worked on many desktop computers before. What is a faster CPU that I can uprgrade to. I was hoping somewhere around Athlon 2000-2400. Someone said that a Athlon 1700 would work for sure ( if I used a 1700 would I have to alter the chip in any way or could I just switch it with the 900mhz?)Like I said I don't know that much about changing CPU's in laptops and I would like to know what CPU I could just swith with my duron 900 without much work. Someone was telling me that laptop CPU are not usually upgradeble? Or is that just usually with intel chips?

Thanks[ ]
I could really use some help...and a faster PC [ ]

 

Well I upgraded my presario 723rsh with an Athlon XP-M 2400+ (1800MHz). It works fine except for the fact that its running at a 100MHz fsb, which with a 13.5 multiplier is only 1350MHz. I currently trying to find a way to make it run at a 133MHz fsb.

 

Hey ciccillover,

Do you know what pll chip the motherboard has? Thanks.

 

Are all the compaq presario 700 models built with the motherboard?

 

So what would be a safe CPU to upgrade my presario 700 with a duron 900mhz to?

 

I believe all the presario 700's came with pretty much the same motherboard. The only differences are some had 128mb on board ram and some had 256mb. A safe upgrade would be a pre-xp mobile athlon. I may have to mess with the bridges on my xp-m to get it to run at full speed on the 100mhz bus.

 

What are the pre-xp mobile athlon cpu's?

Sorry for being such a noob lol

 

Forgot to say that the PCR file used to get the chipset to run at 133 was the KX133's one, I didn't have the KT133 PCR file (and I don't have it, yet).

SargentNG, offset 68 is only to change dividers, if I remember correctly.
Unfortunately I can no longer check as my 722EA seems to be DEAD!
It just doesn't boot up, althought hitting the power button makes the LEDs turn on...

It worked on my laptop, however. My friend got it running at 133 MHz FSB for me (since I was a bit afraid using this program).

However, another solution for changing the FSB would be knowing the PLL chip, as you said, but I don't know which one is on this motherboard.

Do you remember which offset the fsb setting is in?

 

No, sorry

Do you know which pll chip this motherboard uses (so I can try cpufsb)?

 

No, and googling for "Presario 700 PLL" gives no useful result.
However I took a look at the motherboard a while ago, and I couldn't find it... maybe it's something similar to nForce2 motherboards, which have a different method to generate frequencies for the various buses?

Hello, I've just put today into my Presario 722EA 2400 mobile cpu, exacly the same as SergentNG. Does the problem with 100 MHz FSB become solved ? THX

 

leonkilla, where are you from? Are you Italian?
The FSB problem hasn't been solved, but I'm working on it, because my 722EA LIVES AGAIN!
I just tried switching it on again some days ago and it works flawlessly now.

However I have received the Thorton 2400+ that was tested and stable as a Barton 1800 MHz (that is a 2400+) with just 1,35v.
With regard to the FSB I can say that the default value is set to 100 on this CPU. Maybe it's enough to put the default FSB at 133 MHz (playing around with the L12 bridges, if I remember correctly).

I really can't remember which offset my friend modified with WPCREDIT to get it at 133 MHz

SargentNG, can you pass me the KT133 PCR file?
My email address is just like my nickname, just add @despammed.com

Now I'm just testing if it's really stable at those settings or not. If yes it will be modified and tested in my 722EA. It should work just fine.

Hi
All that you have written is like a magic for me
I dont know this stuff at all.
I leeched all the software that is described in this topic,
and after tonz of FAQ's that I've read (how to use WPcredit) I didn't
find any about changing FSB - only some stuff about memmory timings.
I dont want to root through that stuff cause i may damage something.
So i will look at yours and other people improvements in this matter and
give me please prospective description how to increase FSB through WPCREDIT
or the other way to do this. I'm from Poland. Greetz !

My cpu is set 133 FSB L12 bridge by default. Though, Presario sets it at 100 FSB. Wpcredit - I've tried to edit some bytes but I do not have the freedom that I'd like to have. Unfortunately I do not know why the memmory can't be set symmetrical to the cpu (133/133) - there is only cpu at 133 and memmory at 100 or conversely. I have tried both settings but in this situation my laptop was out of order all the time - unable to work. I can't check CPUFSB because I bethink myself to tune my laptop's fans - after the modification they stopped to work and I am forced to buy the new ones.

 

Hi. I have a Presario 722EA and i don´t know to much about notebook's hardware. i would like to know about upgrade video card (S3 twister K is obsulete) and processor (it's 1100 AMD Duron)and to expand the options in BIOS that's very limited.
Elucidate me please if the processor is the same as a desktop computer.

Using cpufsb with my 723rsh 1.0ghz duron, I have found that the system adds 33mhz to the memory, ie. 133mhz. When sandra reports fsb for cpu at 110mhz, it shows memory is at 145mhz and (not great for normal pc133 memory). The system works with a 115mhz setting w/cpufsb however it becomes unstable above that. I see the ability to set fbs at 133 and bus at 33.3, for use with 266mhz cpu's, but the question of the additional +33mhz to the memory makes me wonder if it'll work.
The cpu's with 100fsb x2, such as axmd1800fqq3(B)should still work and you could still bump up the fsb to gain some mhz. I am going to try that AXMD1800FQQ3B (about $60.00) as we don't know yet if the
AXMD2400FQ4(C) at 133mhz x2 will work with that memory at 166mhz.
Please try cpufsb out and run sandra to see if thats what u see.

 

wpcredit (offset 69, bit 7 and 6 both set to 0) can make the RAM run in sync with the CPU, that is 100 MHz.
However even that way my 722EA freezes at anything above 115 MHz.

You should forget about upgrading your laptop if you don't know how it works, IMHO. The VGA and the BIOS, for instance, can't be upgraded.

I dont know what is wpcredit (offset 69, bit 7 and 6 both set to 0)
Sorry but you can explain better?
I only know how to overclock an ASUS board because you have that option in bios but in presario 722 I only can change the video memory 16mb to 32mb
Teach me please.

This is for advanced users only, sorry, but I think you might avoid doing that, especially since you don't fully understand what this procedure can lead to (that is hardware damage).
And furthermore, it is offtopic, in this thread.

I know how to increase frequency and the limits. I just dont understen how in this model ok?

Can you help me?

You can't increase the frequency. You have to change CPU.

Hi,
this thread is very interesting for me, since I've a Presario 700 with 900 mhz Duron.

Plz forgive my bad english, I'm Italian...

I'm a newbie so I would know only if I can switch a normal desktop cpu with my mobile Duron, and if performances will improve a bit without changing fsb.

Please answer me, thank you!!! [ ]

 

Hey, I'm Italian, too!
However no, you need a Mobile CPU, 35w or less in consumption.

Presario 722EA. Mod in progress.

 

Hello all,

I have a 1.4 Athlon 4(1800+) I also have a Barton XP-M 2500+(at 1.45v it's 45W not a big deal I can mod the voltage to 1.35v and slow it to 2400+ speed if I want to stay within the 35W spec)

So of course I too am interested in the 133FSB. This chipset is supposedly a KN133(Mobile, Integrated grahics)judging by the EVO n115 spec sheet and the TwisterK designation. If we look at this document

http://www.via.com.tw/en/products/chipsets/legacy/kn133/

It states that a 133(266)FSB is supported. Also Ciccillover has stated that a friend got his Presario to run at 133FSB.

Using WPCREDIT and looking at the registers on my laptop and comparing them to a KT133A that is running at 133FSB here

http://www.lostcircuits.com/motherboard/asus_a7v133/5.shtml

I notice that a difference is offset 68 and 69. 69 is basically setting bit 6,7 to zero, as discussed earlier in this thread(Setting CPU=DRAM) which works and sets both to 100MHZ. Now offset 68 is different at bit 0. Using the KT133.pcr it states that bits 0 and 1 set the system bus freq. 00 = 66MHZ 01 = 100Mhz 10 = 133Mhz. Mine is bit 0=0 and bit 1=0, while the KT133A at 133FSB is bit 0=1 and bit 1=0(or 40hex vs 41hex for the later). If I try to change bit 0 from 0 to 1, nothing happens and the bit stays as it was. Also it's curious that 00 on my system is suppose to equal a 66Mhz bus which is obviously wrong and I cannot change the bit I would like to. It makes me think the chipset is locked this way, yet Ciccillover swears his friend had it running at 133(Where is this friend now?). Maybe a different BIOS revision locks/unlocks it?

What does your guys offset 68 read? Can you change it to 41hex?

Also for offset 69, bit 6,7. Since we know 00 is 100FSB/100RAM, 10 is 100FSB/133RAM, that should make 01 133FSB/100RAM and 11 133FSB/133RAM right? Well either of the last 2 combos locks my system up just for the record.

Worst case scenario you do a wire/paint mod to set the max multiplier, and control multiplier and voltage with MSRCPU and run at 100FSB at 1.8Ghz of the Barton 2400+. Also it's important to realize that from what I can tell, there was a rev to the heatsink fan combo by Compaq. I have 2 heatspreaders here. One says 35W on it the other doesn't. The 35W has a much larger fan, and air duct. Something to keep in mind for the people wanting to put a Barton 2400+ in, you may have some problems with heat.

Finally a bit off topic, but not really. I noticed in WinXP home that the Athlon 1.4Ghz I have only runs at 800 something max if I have power management config set to laptop/portable with or without AC, but runs all ranges and multipliers when set to desktop, or other. When I put the Barton in, it runs at full speed all the time and doesn't adjust the multiplier(i.e PowerNow doesn't seem to work). Although it does seem that I can alter HALT timing and get a lower "avg" CPU speed? Anyone with a Barton seeing their PowerNow working properly?

Cheers

 

I've been doing work on a Presario 715us and I've noticed that the current processor in it is getting a bit too hot. Its an AMD Athlon 4 1.2ghz. It has the KN133 chipset so I'm assuming I can put a 266 processor in there. But, the main reason I would want to swap processors is to find a core that runs cooler. However, there is no way to change the vcore in the BIOS. Is there any other way? Also, way is CPU-Z telling me that the current vcore is @ 3.888. Just a TAD high lol.

Thanks, Matt
