Problem with CPU Upgrade

Hi everyone,

I recently purchased a Gateway M-6862 notebook which came with a t5750 core 2 duo cpu clocked at 2.0 ghz. I tried to upgrade it to a t8300 but it seems like it isn't running as stable or up to par. I checked on CPU-Z and it shows it running at a lower clock speed because of speed step. But, when I open something, the cpu shows the right speed. However when I run games like Crysis which could run fine on the t5750, it actually runs a little slower. Weird right? Considering that the t8300 is 45nm and with 800 fsb and 3 mb cache and 2.4 ghz. I don't know if I did the installation wrong, but I had anti-static gloves, did it in a hardwood floor room, used 91% isopropyl alcohol to clean the contact points, and used arctic silver 5. I unfortunately did accidentally touch some of the pins of the t8300 but I had gloves on. I checked all the pins and they were alright. There was a sticker on the pin side of the t8300 that I had to remove with a flathead. Had a few scratches on the green part of the chip not too deep. Did I destroy my CPU?

 

Be sure to upgrade the notebook's BIOS to the latest version, to ensure compatibility and support with later CPUs.

 

the t5750 is already a pretty good cpu. the .4ghz difference isn't noticeable really. For games, i would expect a graphic card would do you better than a .4ghz upgrade cpu.

 

The T5750 is an ok CPU.

But compared to the T8100, the T8300 is Penryn (45nm) which is cooler running, quieter, and the T8100 has more cashe.

Anyway, .4GHz is noticable, not by tons, but it is a performance increase.

 

Doesn't the T8100 have a 800MHz FSB compared to the T5750's FSB of 667MHz?

 

Yes, but it cant use it anyway, with Santa Rosa limiting it to 667MHz Memory clock speed.

 

Regardless, it still runs at a 800FSB. The CPU runs at 200FSB x 12 instead of 167FSB x 12 which will have an effect on memory bandwidth.

 

True....my W.E.I. memory score increased when I upgraded from a T5450 to a T8300.

 

Oh, ok - In was not aware.

 

I agree that it increses proormance, but WEI isnt anything to benchmark on. Its innacurate.

 

Its easy.

I'll use the T8300 as an example:
_____________________________________________

Divide the "FSB" by 4 to get the "CPU FSB":

800/4 = 200MHz


Now divide the processor frequency by the "CPU FSB":

2400/200 = 12

Now we know that the CPU multiplier is 12.

 

Benchmark your T8300 in wPrime (32) and compare that with the results others with the same CPU get. Then run a 1024 stability test in wPrime to see how it works under extended load. If both those check out, you should be fine.

Also, run HWMonitor in the background, I never run any benchmarks without a temperature program running as well.

 

Interesting... Thanks.
