Penryn CPU upgrade

Hi folks,

I'm new here, but sought some leeching type advice a few weeks ago.

I wanted to upgrade my HP DV2533TX laptop cpu.

Standard was a T5450 1.6Ghz 2M cache, 667FSB. SLA4F. M0.

I decide to get a T7500 2.2Ghz, 4M 800FSB. SLA44. E1 stepping, based on 'learned' advice that HP machines only accept certain stepping CPU's. Maybe. Somehow I decided on the E1 version.

HP Live chat told me "NO you CAN'T change the CPU in DV2500". I did mention i didn't care about the warranty.

Ha, I searched & downloaded the HP DV2533 service and repair manual. Running the 2.2Ghz chip perfectly. So many screws. sigh.

Nice. Fast track 4 weeks later. I downloaded a bios update F.21. Readme says..... "Includes Penryn Support". Pardon?

Ok, Ebay again. thought of the X9000, but 44w of heat and advice from others they have been tested @ over 100C in certain laptops scared me.
The T7500 does 92C under full load @ 35C ambient.

So, T9500 then, 2.6Ghz w/ 6Mb @ 800fsb. B1 version (ES), Q4GG (Would rather the Q9WW C0- production version/ready) for $A500 delivered from Korea.

Arrived today, got to fitting, fresh ArticSilver5. First boot- and seems to have unlocked extra stuff in bios options.

HWmonitor won't read temps so no idea how hot.

But successfull so far. Shame I can't have the new DV2700 series 128Mb dedicated graphics ram instead of 64Mb..maybe motherboard change!!!.....or the 8600 chip of the DV9xxx... model.

Also appears this laptop has provision but no socket for another mini pci express port... ala Intel Turbo Cache...or something other than the other internal wifi jammed in the only available port.

Anyhow. Just news for the interested/curious/owners out there.

Interesting... =D

 

very interesting. try downloading PC Wizard 2008 from CPUID and see if it reports on your temperatures.

 

any wprime or super pi test result?

 

So Far, PC Wizard reports ACPI Thermal Zone as #1:70C, #2:68C
(nvidia 61C)

Idle-ish, wireless net, writing email. Ambient temp 34C.

Processor Temp. Tmax 85C.

Voltage as reported by cpuz and pc wizard @ 0.9 - 1.25v.

Same idle speed as T7500 - 1.2Ghz (x6)

I'll run UT3 for a while and see if it changes.... The fan goes MAX.
Even tho it's 8400GS nvidia and 4gb ram.. i only get 1 on the texture scaler.

I didn't want a physically large laptop, but need / like grunt.

No.

3dmark06 result was actually the same as the T7500. 1075marks.

But CPU speed better. Have the output files. No screen capture though. Useless Vista WEI Index for CPU went from 5.1 to 5.5.

This laptop is GPU bound for anything decent gaming wise.

Has 4Gb RAM, 160Gb SATA. 8400M-GS Nvidia Discrete graphics with HDMI.
I will buy HD-DVD or Blueray drive later for it. Good for HDTV and Multitasking.

But UT3 demo play nicely in 1024x768. I think the game runs way smoother than last night. (Got the T7500 to 92C and the Gpu to 105C) HOT!!!

SuperPi mod/ 1.5XS : 1M, Result: 18.96
Prime158 32M Speedtest: 30.61

pics or ban!!

gets some screenshots up of CPUID, 3Dmark06.. anything!

 

T7800 wprime 32M 31.472 vs T9500 30.61
T7800 super pi 1M 19.578 vs T9500 18.787
T7800 WEI 5.4 vs T9500 5.5

 

Aw, You talked me into it!

prime is a little slower today, but Superpi was quicker... best again of 3 runs.

 

coolest thing I have seen in awhile gets my tech savvy side all fired up.

 

sweet! wow .. 18secs on SuperPI 1MB with a notebook, no wonder SuperPI is being retired by many.

 

ummm...wouldn't it just make sense to increase how far you resolve the equation of PI to 2MB or further?

 

I freaking knew it, thanks for proving it right. now i could get my xps1530 and swap it for a penryn!!

 

yeah, but what was the point of testing it at 1MB before? Benchmarks are used for comparing results from old and new processors, upgrading to a 2MB will only lead to an upgrade to 4MB later on with absolutely no value for previous benchmark results from the latter numbers(1MB). The fact is, SuperPI is becoming too "easy" for modern day processors which is what I meant from the previous post.

 

Out of interest, I noticed t9500s are relisted on ebay.

I'm gonna have to disagree with you there. people still run the older 3DMark programs even tho the newest is the one to compare against. they getter harder and more intensive as the hardware breezes thru the older benchmarks. you would start doing a 1MB to compare against the older processors to show how good they've become and use the 2MB or 3MB and higher, to test against the more modern day CPU's because they can do it whereas the olders can't (note, they can, but it takes significantly longer to do, hence why it's the new test level for modern tech).

just because one feature doesn't work as well as it used doesn't mean you need to replace it, you just change the methodology. a 2MB or higher test is going to take longer. as the CPU's become more capable, you'll continue to up the intensity of the test.

 

Except were forgetting the main reason why SuperPi is no longer used, it's purely singlethreaded. And last I checked, no one processes only one thread at a time any more.
