Looking to upgrade CPU of my L702X laptop - Page 2

got any links for that 30%? from my quick research i didn't find a definitive number and would love to get educated.

Intel Core i7-2860QM @ 2.50GHz you say?

But the 2860 uses a different socket: BGA1224 instead of PGA988B

The most powerful supported cpu is the Intel Core i7-2960XM (which is a very expensive cpu -- not worth the money)

Does 45 TDP vs 55 TDP matter with my laptop? I think I have a 130 watt power cable. (3D version Dell XPS L702x)

The sandy bridge mobile chipset only supports sandy bridge CPUs, the Ivy Bridge Mobile chipset is backwards compatible though. The 3840qm is an ivy bridge CPU, I personally haven't seen any notebooks with a sandy bridge chipset run an ivy bridge chips. That 2960xm is probably not worth the money, especially if you can't overclock it.

http://ark.intel.com/products/53476/Intel-Core-i7-2860QM-Processor-8M-Cache-up-to-3_60-GHz

http://ark.intel.com/products/52219/Intel-Core-i7-2630QM-Processor-6M-Cache-up-to-2_90-GHz

looks like the 2860qm is available in 2 socket types. I'd be interested to know what the difference between the Chips are. You could buy the step down model and buy the 2820QM, it is only the 988 pin, or make sure the 2680qm is the 988 socket before buying it. Also check ebay you can get some good deals on their.

As for the guy saying hes getting blue screens on the other forum, I can't imagine a processor upgrade causing blue screens. A 3840QM in a sandy bridge chipset might cause it, I can't believe it would post with an unsupported CPU in it.

Now what do you hope to gain with the CPU upgrade. I can't imagine that 2630qm is holding back the GPU in that laptop.

The GPU isn't holding me back, but the CPU usage is always quite high cpu (70%~) usage because i'm an extreme multitasker which causes frame / performance drops in general.

It's not because of tons of bloatware because I keep my system clean.
So yeah a 30% performance increase would drop cpu usage wouldn't it?

I am also looking into customizing the cooler somehow, maybe hax a replacement but no luck searching lately.
Any suggestions are welcome, i'm currently waiting for a cooling pad to see if temperature drops; will also try that arctic thermal paste (currently using noctua).

So i need to see if i can fix my heat issues while maintaining the portability of my laptop.

Thanks

Um... that's not normal... you shouldn't be running at 70% CPU usage unless you're running like, 20 programs at once, and no... that's something on your machine. My brother's laptop has an Ivy i5 and he sits at 50% usage at all times. It ruins his gaming experience.

I run like... 1%-5% idling at the desktop after minimizing a game or two and having several tabs open in the background and listening to music. Often times I run out of available RAM before I can effectively manage my real CPU horsepower. So no... you're better off just sorting out what's dragging all your CPU's potential away.

70% usage on an i7? that contributes to your heat issues im sure. If the CPU is that loaded all the time then its working hard. Id try repasting, and blowing out the heatsink vents, and make sure the fan spins properly.

What cooler did you get? keeping the laptop elevated with cool air moving underneath it should help a lot.

Currently idling(1-5%) at 45-50 degrees Celsius (max temp so far was 78 degrees Celsius) cleaned with air compressor, re-pasted with noctua thermal paste and using a laptop stand (external cooling) CM STORM-17.

I still wouldn't mind upgrading the processor to see a 30% performance improvement when doing heavy multitasking...

But I'll settle with this for now and see if the 400$ upgrade to 2860qm is really worth it as the 3840qm would have been more like a 45% performance boost for the same price.

Sidenote: possibly when doing heavy I/O my cpu may lose performance due to fully encrypted laptop drives (1 SSD & 1 HDD)? My BIOS doesn't have the option of Hardware Encryption.

And yeah, I run 10 programs at once quite often.

Cheers

Yeah but unfortunately you're not capable of upgrading to that. It may be worth it for you to buy an XM CPU then, verify your laptop can support it first!. I've never ran an encrypted drive. Don't know the performance it it makes.

Your max temp was 78*C? Your machine shares a heatsink array with the GPU. It doesn't strike me as a good idea to upgrade to an XM CPU for any reason. The 2860QM is probably a bit on the expensive side still, so maybe look for a 2760QM like me? Added 400MHZ at stock and sits pretty at 3.2GHz under 100% load (All Cores!) makes all the difference in the world...

That's a good point. the XM will probably run too hot. I didn't think about the single heatsink that system likely has.
