Thank you, have a nice day.

By the way, R61e's are insanely cheap on ebay.

 

So you got no POST with the T9400? Some laptops will POST but instead of 1066/266.5 it will run at 800/200 x CPU multiplier.

So a T9400 is 266.5 x 9.5 = 2531 = 2.53 GHz
If it did POST 200 x 9.5 = 1900 = 1.90 GHz

So you'd be better off with that T9300.

 

That's correct. With the T9400 it would immediately shut off, never making it to POST.

 

The R61e can only take 800MHz FSB Core 2 Duo's so theoretically the highest you can put in is the T9500. That said, the T9300 is a decent processor as I have this in my T61 and provides enough power for my work.

I use the R61e as a work machine and its solid piece of kit, heck it even survived when it was in my car boot during an car accident (lorry smashed into me) and got thrown into a ditch. Except for a small chip on the bezel but everything was fine as if nothing happened which is testament to its build quality.

My one comes with a T8100 as standard and runs very cool (29c on idle). The only downside is the screen resolution (WXGA), though should my Uncle's R61 give up (it has the NVIDIA timebomb) i'm going to be like a vulture and have dibs for the SXGA+ screen to do a transplant!

 

lol Hearst, such a great way of thinking.

Is it possible that Lenovo whitelisted the CPU in the BIOS? I believe some laptops will actually POST with higher rated FSB Core 2 but again run at 800 FSB rather than 1066.

 

Do you know if the WSXGA+ upgrade will work for our r61e's ? I have been looking into it, but will have to sell off some more of my parts before I can really consider it.

I wasn't expecting the T9400 to work, however I had it laying around so I figured it was worth the try. Isn't the X9000 the highest these things will go?

Perhaps. My line of thinking was that with this liberated BIOS, if the hardware supported it, it would work.

 

I think you can put a WSXGA+ screen inside the R61e, it's even listed as an official part under the R61 family.

 

yes you can use the WSXGA+ the GPU can support the resolution, the display cable and inverter are directly compatible according to the hardware parts list.

 

Thank you for the post. Was curious what a T9400 would do when installed in a 965PM (800Mhz FSB) system.

Your results make sense. The 965PM chipset receives a 266Mhz BSEL signal as set by the CPU but doesn't what to do with it. The datasheet even says the chipset will shutdown upon receiving an unknown BSEL. Masking the BSEL pins on the CPU to replicate a 200Mhz signal might work but the chipset will then evaluate the CPU BSEL (266Mhz) and the BSEL it received (200Mhz), note it's different, then apply Intel's anti-overclocking feature of locking EIST and setting the CPU to run at x6. So 200x6=1.2Ghz would be the result IF it posted.

Best bet is a T8300-2.4, T9300-2.5 or T9500-2.6. The T8300 the best one to use, due to having less cache, if trying a FSLx PLL pinmod from 200->266Mhz. R61 might have similar internals to the T61 so could evaluate the info here if interested in such a PLL pinmod overclock.

 

If i was to upgrade my processor to t9500 (i currently have T7100) Would i also need to change the cooling fan?

 

no. You can use the stock fan.

 

Ok this message isn't about processors, I've noticed whenever I reload my PC and when i first got it (lenovo r61e 7649) it came preloaded with 'integrated camera' software on the start menu, when i click on the folder all it says is uninstall, so i assume that it's installed, But whenever i try to use webcam, this so called integrated camera does not exist.

Why have software preloaded onto the PC when it does physically have the feature? Does this mean I need to buy an integrated camera and a case for where the screen is to fit the Thinklight and Integrated camera in to?
