Hi, I have a compaq presario V5101us laptop (v5000 series)

My original cpu and motherboard has this :

Mobile Amd sempron 3300+ (socket 754)

Mother board hp 30AE

cache L1(d) 64Kb..... L1(I)-64Kb..... L2- 128Kb  ...I got this information from CPU-Z

I dont really know if u need to know the chipset but its (ati xpress 200)

But anyways I wanted to know which of the 2 cpu's better and compatiable with my laptop:

AMD Turion 64 ML-40 or AMD Turion 64 MT37 Lancaster 2.0GHz Processor

OR If you have a better cpu that works better I am all ears. The thing is my cpu is slow and I am a gamer and want one that doesnt freeze when

I am playing games like BF2, Halo, or World of War Craft ..I had this laptop for maybe 3 yrs now and since the warranty is over i dont mind upgrading it.

on secound thought where can i buy a amd turion 64 mt37 cpu i looked everywhere looks like everyone was out of stock...i was planning to buy one thats when i said wait if amd turion 64 ml-40 is better i rather buy that. but anyways

Got any ideas?..

So after looking up your laptop I found that this was the only CPU to ship with that model, so there is no guaranty that it will work. It may work fine with another CPU, or it may force it to 2.0GHz thinking it is your old CPU. I would suggest upgrading to 2GBs of ram before trying this.

Wait  so what i have already is the only one that will work my laptop or the one's i mentioned 

And i did upgrade my memory from 512 to 1.2Gb of ram but not much performance change in speed and gaming

I also found this wonder if its any good..

1.8GHz AMD Turion 64 Mobile ML-34 800MHz 1MB L2 Cache Socket 754 OEM
if so is it better then what i have now?

Newer CPU's can run in older boards, but usually a BIOS update is required. Bob is right - your laptop was only available with the Sempron 3300 and no newer BIOS updates are posted on the manufacturer's website. If you are feeling adventurous you could always visit Ebay and buy a used Athlon 754 CPU for CHEAP and throw it in there and see if it works. Your current Sempron only has a 128KB L2 cache, and an Athlon will have at least 4 times that. Most people would not see a big-enough performance gain swapping in an Athlon (if it even worked) to make it worthwhile, but you might like to try it because you love a good challenge. By the way, welcome to HotHardware, rtism!

Thanks

I'll try it hope its not to hard to take apart my laptop. I hope it works and its better

I found this while i was browsing the web?

Customer Reviews for AMD Turion 64 MT37 Lancaster 2.0GHz 1MB L2 Cache Socket 754 Single-Core Processor - OEM

Great Processor

Pros: Good performance!
Much faster than the sempron 3300+.
Lots of cache memory!
Simple install, no problems
Great for Compaq Presario V5000 series with a sempron or lower turion64.

Cons: Not x2 processor.

Other Thoughts: This is a much faster processor than the sempron 3300+ that came with my compaq v5101us. It was pretty simple to replace the processor. I also replaced the RAM with 512MB stick and a 1GB stick. I recommend this product to anyone that owns a compaq presario v5000 series that uses a sempron or a lower turion. processor.

I was thinking an Athlon like THIS might work, but it appears that you found someone who got an MT-37 to work (check THIS out). When I decided to upgrade the CPU in my Compaq R4000 laptop I went to the Compaq website and was shocked to discover the instructions for the complete disassembly of the laptop - right down to the removal of the motherboard! Hopefully your laptop has similar documentation, too. Good luck.

Yea..I found hp website that showes the complete instructions to take apart or replace hardware of my laptop

This is gona be intrusting...wellthanks for all your help

Remember to label screws and take your time cracking open the lappy. It will make closing it up much easier.

lol i will take my time dont work i dont want to mess anything up " Now does this go here or there..oh no..NOOOOO!!"

I still like my lappy
