compaq presario c301nr core2duo upgrade possibly? - Page 2

Good luck, Digg! What's a VT, BTW?

guyin916, Any luck on the CPU upgrade? I have a C509 and tried a T2050, but only get a BLANK screen upon bootup. I upgrade t the F.14 BIOS, but it still will not boot with the T2050. My celeron works fine. I wanted to see if you had any luck on upgrading your CPU. If so, did you have to do anything special. MrAce21

guyin916,

Any luck on the CPU upgrade?

yeah I hate to bump this thread, but Im wondering if guyin916 had nay joy upgrading the cpu?. Ive upgraded the firmware and have 2 sticks of PC 5400 667MHZ OCZ memory .

if theres a step up celeron id be content with that, im curious what other cpus by intel might work?.
a core solo? or just plain ol duo core not core 2 duo

Oh yeah I have no problem waiting a month . Id wait a month to see if you had any luckthan get another laptop since im on the same boat as you sorta minus the cpu lying around hehe. but if that works then heck yeah, I see a T2250 for sale but no point in buying that if it dont work.

Everyone who is still wanting to upgrade the Celeron M (420/430/440) should read post #11. It has been discovered that the motherboard's chipset is the Intel 940GL chipset, which absolutely will not support any CPU above a Celeron M 420/430/440, none of which CPUs support Hardware Virtualization or SpeedStep Technology. (But you can run VT software such as VMWare or Virtual PC -- it just won't be as effective as if it were running on a notebook capable of hardware virtualization. Kind of like running it in "soft" mode, and much poorer performance.)

The second of two BIOS versions (F 14.A) does nothing to enable a CPU upgrade above the Celeron M 420/430/440, but doesn't seem to introduce any new problems, so flash away, if you like. (I did.) The notation on the BIOS update that BIOS version F 14.A introduces support for the T5500 CPU does not apply to our C301nr model. That BIOS is used across the C300/C500 and V3000/V5000 line of notebooks.

All C301nr's should handle 667-MHz DDR RAM just fine, but of course the RAM will run only at 533 MHz. I'm jusing 667-MHz RAM in mine. (I bought the 667 RAM thinking I could upgrade the CUP to a 667-MHz CPU -- sheesh!)

I think the reason we're not hearing back from the guys who said they were going to try such-and-such -- is because this notebook is dead in the water as far as upgrades. Unless someone's doing a BIOS hack, which I just won't do. Anybody?

I was wondering if you had any success with the T2250?

Don't know if this will help but here it goes. My brother has a dv6000 that came w/the celeron processor and I changed the processor w/a 1.8ghz dual core. Ill get the details on the board chipset and exact processors involved if you still need some insight.

Take the C301nr to 64 Bits!

If you consider going to 64-bit computing an "upgrade," then do what I did:

Flash the BIOS with version F.24 A* and install a Celeron M 520** (SL9WT).

Vista 64 Home Basic*** installed without a glitch.

The 64-bit drivers included on the Vista 64 DVD provided full functionality for the C301nr except for Quick Launch Buttons (same as in a 32-bit installation, if I recall). HP's download page for the C301nr has the 64-bit QLB driver, as well as newer drivers for some of the ones installed by my Vista 64 DVD.

After "upgrading" to 64 bits, my Windows Experience Index increased very slightly for the Processor/Calculations per Second" component, but it feels more stable and responsive than 32-bit.

NOTES:

**BIOS F.24A "provides support for Celeron M 530." (That's why I tried it with the 520 that I bought for $30.)

*** I installed the RC-1 of Vista 64 Home Basic because I didn't have Vista 64 Gold (RTM). So your mileage with drivers may vary. It appears that even though the CPP/Beta time expired before I even installed RC-1, since I didn't provide a key or auto-activate online, it will let me run RC-1 for 14 days.

OTHER:

The Celeron M 520 clocks at 1.6 Ghz, slightly slower than the stock Celeron M 430 that came in my C301nr. The Celeron M 530 is clocked at 1.76 GHz.

CPU-Z (v. 1.39) reports the Celeron M 520 as a Core Duo (Core 2 Duo?) Merom CPU, but we know better. I may need a newer version or a 64-bit version of CPU-Z.

The Windows Live OneCare Beta 2.0 (just out) is now 64-bits.
I'm so sick of taking this C301nr apart and putting it back together. (I had tried many of the same CPU upgrades mentioned in this thread before FINDING this thread.)

REQUEST:

The latest BIOS (F.24 A) file size is almost twice that of the previous F.14 A file size. Do you suppose the new BIOS now supports any of the Core CPUs already tried and mentioned previuosly in this thread? (See CPU-Z, above.) Is anybody ready to try AGAIN with a Core CPU?

I am also very eager to know if my upgrade to 64-bitting will allow the C301nr to recognize more than 2 GB of RAM. (Wish I could afford to try it!) Anyone?

Please chime in, readers.

someone has upgraded this chipset with a core solo, whoever had the t2050, was it a compaq/hp specific chip or did you just buy it from the store? i've been informed that hp laptops will only work with hp chips...

I've just upgraded CPU to Core Solo T1350 today. It works well.
My laptop:
Compaq C301NR
chipset: 940GML (see post #11)
original CPU: Celeron M 430
current CPU: Core Solo T1350
current BIOS: F.24A

Although Intel stated that 940GML supports Celeron, it supports Core Solo FSB 533 such as T1350 with an appropriate BIOS. Speedstep flawlessly works as my expectation.

the newest bios says it adds support for Core 2 Duo T5500. its from may, but i just now looked at it.
