[Upgrading] MX7525

Hi guys,
I’m looking to upgrade the all around performance of my MX7525. Since I’m somewhat new to the world of laptops I figured I’d check with you guys.
I recently posted a thread about upgrading the ram in the machine from Pc2700 to PC3200. I was informed that due to power restraints that the system would not allow you to sync the FSB with the Pc3200 ram.

That being said, I’m having trouble finding 1 gig Pc2700 stick, would it be problematic to use a 1gig Pc3200 stick under clocked to Pc2700?

Also I wish to upgrade the HDD since it’s a slow POS. Is there anything I should be aware of when replacing the HDD? Can I stick any 2.5” drive in there without worrying? I was thinking of going along the lines of a Hitachi Travelstar 7K100.

Thanks,
SyN

 

RAM: Just go to NewEgg and get the 1GB PC2700 stick, because I can't guarantee a PC3200 downclocked will work.

HDD: I'm using that one right now, and my notebook model has the exact same chassis. You'll find that drive'll actually lower your temps, interestingly.

 

Thanks Pulp,
I got more Q's.

Regarding the ram, I want to ensure I dont run into a ram timing conflict when upgrading. Can someone confirm what is the default ram timing of the stock ram? or may be sugest an app which would show the current ram timing?

Thanks,
SyN

 

uhh there is no fsb on an amd64 system. Its Hypertransport and a system bus since the on board memory controller. You are constrained to what the motherboard can support. That mobo will clock 3200 to 2700, and when both slots are full, you will be running at 2100. Thats the thing. The best way to increase performance is really to change the stick under the keyboard (oops waranty no good now) to a 1gb or something stick and empty the user accessible slot.

 

Oh thats blows chuncks. Pc2100 when both slots are in use.
Ok lets talk about replacing the the ram under the keyboard.
I checked out the hardware pdf which came with the mx7525, and there is a section which covers removing and replacing the keyboard. There is a picture shown after the keyboard is removed and still I cant see the ram slot. There seems to be a metal plate held by screws underneit the keyboard. Does anyone have a step by step to upgrade the ram found under the keyboard?

 

usually there is a metal plate of some sort covering the ram to prevent damage from pressure on the keyboard.

 

USCOOPEER:
I can't quite get why the 2100 when both slots are full....how did you come to that? Did you test your laptop?
Please expand your explanation about that....interesting topic (or disapointing).
Thanks!

 

I experienced the same thing back in the day with my Asus A7V333 mobo. Once all ram slots were taken, it would drop from 2700 to 2100. This was something which was also documentated in the mobo's manual.

 

I have to ask as well, where did you get your PC2100 figure? Both slots in my notebook are occupied and running at PC2700. Heck, the frigging MX7525 COMES with both slots filled.

 

Its just something thats ALWAYS been true. I havnt looked it up or anything but yeah any time both slots are full or all (2 on most boards, 4 on a 939 desktop in dual channel) they are automatically clocked down so 3200 runs at 2700, and most notebooks 2700 running at 2100. Just what iv always seen/heard from friends who have home built/ knowledgeable computer guys. The less pins you have the ram on the better. I mean why else would guys install a 2X1gb kit

 

Mhhh...at least Everest reports a memory bus near DDR333...for the memory timings reported its using memory as 166Mhz (non DDR) which brings us to PC2700.....maybe little less but never PC2100.
I tried unpluging but memory clock and timings stay the same, only CPU drops down to 800Mhz (as it should).

CPU FSB 198.96 MHz (original: 200 MHz)
Memory Bus 159.16 MHz
Memory Timings 2.5-3-3-7 (CL-RCD-RP-RAS)
DIMM1: Samsung M4 70L6524CU0-CB3 512 MB PC2700 DDR SDRAM (2.5-3-3-7 @ 166 MHz) (2.0-3-3-6 @ 133 MHz)
DIMM2: Samsung M4 70L6524CU0-CB3 512 MB PC2700 DDR SDRAM (2.5-3-3-7 @ 166 MHz) (2.0-3-3-6 @ 133 MHz)

I've never heard of PC2700 going to PC2100 before.....maybe it's an issue related to older mobos or different chipsets (not 754).

Interesting topic!!

 

Agreed, but the problem is that I've built two Athlon 64 systems in addition to the one I'm using and I have NEVER witnessed that happen. If this were true, any one of the tech websites out there would've broken the story and I'd've seen it. I seriously doubt The Inquirer would let something like that go by.

My real proof is, of course, as follows:
Gateway 75xx series notebooks use two sticks of PC2700 DDR RAM and run at PC2700 speeds.

Oh, and differently clocked RAM sticks all have the same number of pins, so I have no idea what he's even talking about there. The only time RAM has differing numbers of pins is between different TYPES of RAM, i.e. DDR and DDR2.
