CPU upgrading on IFL 90 (from T7100 to T9400 or T8400)

Is it possible? After bios flashing maybe? I have a chance to buy very cheap T9400 or 8400. Thanks in advance!

 

no, yesterday, now and tomorrow

 

T8400, t9400 and t9600 are off-limits due to the 1066mhz bus speed, if you really want penryn you can try the t8300,t9300 or t9500 they work there was a thread about the thermal sensor reporting incorrect temps leading to a complete system failure but apparently some people have motherboards with compatible sensors and they didn't report any problem... To play it safe why don't you go with a t7500 or t7700?

 

OK! T7500 or T7700! But, Is there any significant difference in speed between these two processors? I know that 7500 work on 2.2 and 7700 at 2,4 and rest (amount of cashe etc...) is same.
But if the price difference is too big, i will try to find T7500.

 

t7700 is hotter.
I have it, and I have chosen a t7500 today...

 

I'm happy with my T7500, it's very good proc. it gets about 1930-1950 points in 3dmark06, idle temps are - 44 - 54C; gaming - 65 - 85C

 

You have one T7700 extra??? Send it to me ) Because here in Croatia it's very hard to find something specific. I have found somehow T7500, but T7700... seems to me I'll never find it (

 

Ive got the T7800 (2.6ghz) in mine and it gets very hot when doing demanding stuff.
But never too hot that it would shut off.

 

What are you doing with your computer? If you are just using it for normal applications, you probably won't notice much difference. I won't recommend upgrading it at all. Chances are, you will be much better off increasing the RAM or upgrading the HDD, by which the results are much more noticeable.

That said, the biggest difference in CPU will be from T7100 to T7300, with the change in cache from 2 MB to 4 MB. Then again, if you are not doing anything intensive with your computer, then upgrading would definitely not worth the money spent.

On a side note, 3dMark06 is mainly for benchmarking the GPU, not the CPU.

 

It's common to test the processors with 3dmark, that way people have some idea about their proc in simple number, and can easily compare to other processors without having much knowledge in the area, so...

 

That is true, but you have to take into consideration that 3DMarks takes in a pretty large portion of your GPU as the final score, which confound CPU performance with GPU (and other components). Sure, the CPU does makie a difference, but it's going to be rather small as compared to the impact of GPU.

All I am saying is that there are more accurate indicators / benchmarks for the CPU than 3DMarks. As to give people a good idea of their CPU performance, I have yet to find 3DMarks as a common mean for benchmarking the CPU. I think you mean PCMarks, not 3DMarks.

 

I'm not writing my overall score, I'm posting my CPU score... the final score in 3dmark is based on 3 things - SM2.0, HDR/SM3.0 and CPU score, the point is that the first two are GPU tests scores and the last one is JUST for the CPU which will (should) score the same score in any system the processor is put in, and that's why peope can compare their processors with that score. I agree there are more accurate benchmark programs for CPU, but this is one of the most popular ones and most of the people use it. You should try several test and see for yourself, cause we've gone too far offtopic.

 

Do you guys really have to argue about CPU benchmarking methods?

 

We are having a nice lil' discussion. Why must you ruin the fun?

 

aahaahahha that's why we're computer forum members to argue about vital things in life.

 

I felt like raining on your parade Anyway 3dmark cpu score may give you an indication of what your cpu is capable of, i wouldn't consider it a good tool for that purpose as nowadays cpu don't do graphics beside when rendering scenes in softs like autocad or cinema4d but even that is probably gonna change with the generalisation of gpgpu computing(you can already defer you scene rendering in 3dsmax to the gpu with the gelato plugin using cuda....) stuff like wprime would be better as it is a really small chunk if data meaning that the amount and the speed of your ram doesn't matter and it makes your cpu work hard.

 

put the t8300 at 2.4. i have a sager 2090 based on the IFL 90 that you have. when i called tech support for it they told me only up to the t7700 is supported, i simple put in a t8300 and it worked just fine. Wprime scores show its working like a t8300 but the temp senors are a bit off. i bought my with the t7300 in august 2007, this little upgrade is really nice. these 45nm chips sure like to undervolt nicely. my t7300 only under undervolted to 1V, this t8300 goes to .9750V but i leave it at .9875V and it works just fine.

 

I've always heard that the sensors were off but how off are they? What kind of temperatures do they report?

 

they seem to be about 10c off on my sager 2090 and the fan stays on high most of the time. the fan seems like it doesnt throttle to low or high it just seems to stay on high. i dont mind it, its keeping it extra cool in the inside. the noise is still within my tolerance lvls.

 

hi, I have replace my t7300 @ 2.0 on X9000 @ 2.8, tempretures became suficiently lower
Ideling -> was 52 - 56, now 34-39 C
Burn(OCCT 2.0) -> was 83-89, now 69-71 C
also I notised that GPU temp fall down
idle was 64-66, now 54-56
burn(Fur (gpu caps viewer)) was 107(with OC), and now 87 (with OC)
I like my new Penryn, besides i wait it to overclock
3d mark'06 CPU Score ~ 2680

 

You can't overclock on the ifl90.

 

Hm, I intrested why.
I notise that PLL registres cannot be write because it's lock in POST proccess, and counter register(x0C) is 0Dh after POST.
I want to rebuild BIOS and unlock it, how do you think - is it possible?

 

If you know how to do it why not, but the cooling of the ilf90 wasn't really made to handle Extreme Edition CPU. Don't forget that there is only one fan and it has also cool the gpu.

 

Do you think so? - please see this thread, i wrote earlier that temperatures are small. I think overclocking is possible in termal description.

 

IFL90 did work with X7800. question is will this notebook support Mobile Quad Core?
