DV7-2XXX: Upgrade CPU to Q9100

Pavilion DV7-2035eg
Microsoft Windows 10 (64-bit)


I basically have the same question as covered previously in this question:


I've got a HP Pavilion dv7-2035eg with C2D P8600

BIOS F.46 08/25/2011

Mainboard HP3624 rev18.51


I am looking to upgrade the CPU and my options are either an X9100 Dual Core or a Q9100 quad core. Accoring to the previously mentioned post and the manual, the Q9100 should work but it doesn't?

In a different thread I saw that you'll have to isolate 5 pins for the Quad core to work properly (see image below), is that correct?


Would a Q9100 give me a performance boost over a (possibly overclocked) X9100? I mostly just use Office, watch movies and edit photos in Adobe lightroom - which is the most resource hungry of the mentioned. If the Quad isn't that much better, the safer bet would probably be to just stay with a dual core... Would either of the two CPUs have a significant speed impact  when comparing it to my current P8600? (I also currently purchased 8GB of RAM and a new SSD which I will both install together with the new CPU).


Thanks a lot!

DV7-2XXX: Upgrade CPU to Q9100

You do not want to rely on overclocking. Here is the Manual:




The Q9100 supposedly is compatible but as you have seen in that older post at least one person has had trouble getting it to work. Software is either optimized for 4 cores or not. Much of it is not. Many games, for example. General internet and Office type apps generally use only 2 cores. Recent versions of Adobe Photoshop and Lightroom are compatible with 4 (or more) cores but it only makes a real difference if you are doing large batch processing. If software can take advantage of 4 cores then yes 4 cores makes a big difference. Otherwise if it is not, then its all about clock speed and cache when comparing processors with similar architecture. You have a P8600 at 2.4 ghz right now. The X9100 dual core Extreme is not listed as compatible. I seem to recall seeing someone report success with it but cannot guarantee. Not sure why people over look the T9800 at 2.93 ghz. Its a beast of a processor. And in this case its listed as compatible and I can think of no reason you cannot go from one C2D to another. With the T9800 you would add .53ghz and double the L2 cache from 3 to 6 megs so I am thiking you get a 30-40% bump in floating point performance. 


Let us know how this works out for you.
