E8335 on HP Pavilion DV6

Hi,

This thread follow this one :
http://forum.notebookreview.com/hp-pavilion-notebooks/648376-dv6-1120ef-cpu-upgrade.html#post8342451

I have a DV6-1120EF with :

- MOTHERBOARD : 518432-001 (BIOS F.46)
- CPU : Dual Core T4200
- CHIPSET : PM45
- RAM : 4Go DDR2-800
- GPU : RADEON HD4530 512 Mo

I would like to replace my CPU with a E8335.

Could you confirm that it's possible ?

Thanks in advance,
Olivier.

 

I think it should work, or at least I can't think of any reason why it won't work.

 

Because this CPU is not listed on the supported CPU in the Dv6 series guide
HP uses some white lists, T9800 is supported but the E8335...
See the other thread : Dv6-1120ef Cpu Upgrade.

 

I received my E8335 and I installed it on my DV6.
My BIOS recognizes it, everything works properly.
But I have just a cooling problem, the E8335 gets very hot, about 100°C !
I think the thermal paste I used is of poor quality, It is a cheap paste that I bought on ebay : HY610 Gold Thermal Grease...
I will buy some Artic Cooling MX-2, it should be better...
Has anyone ever had this kind of problem ?

 

Such situation should be expected, as all T-series Core2Duos have 35W TDP, while the E8335 has 44W TDP, so it generates substantially more heat.

 

Marecki,
There are actually two versions of the E8335 :
- SLAQC (stepping C0) 2.66 GHz TDP 44W
- SLGEB (stepping E0) 2.93 GHz TDP 35W
Mine is the SLGEB, so it has the same TDP than my T4200.

The thermal paste I used :
eBay | 2x Gold Thermal Paste/Grease/Compound ideal for PC PS3 YLOD XBOX RROD Repair

I noticed a hissing noise that appears after a while of use.

What do you think ? What's wrong ? What should I do ?

 

True about C0 and E0 differences. Try to get some recognisable TIM (ICD7, MX-2, MX4) and do a repaste. I have never heard of this gold paste that You've used.

 

Thanks Marecki.
This is what I think too, this paste does not seem reliable to me.
I will repaste with MX-2, is there a good tutorial for that to be sure to do it correctly ?
I didn't change the paste from the chipset, it's a very thick gray block.
Otherwise it can not be a problem in the processor itself ?
I have 1 week to return to the seller, so...

 

Chipset might have a thermal pad instead of thermal paste; if it does, and You haven't damaged it in the CPU change process, You can leave it as it is.

When doing a repasting on a Penryn CPU, put "~half-a-grain-of-rice" drop of TIM in the middle of the CPU core and reassembly the heatsink. This should do the job.

I doubt that the CPU is faulty, unless it's an ES (which it isn't).

 

What is an "ES" ?
What do you think about the hissing noise that appears after a while of use ?

 

ES stands for Engineering Sample. Hissing noise might be coming from coils on the motherboard. Try reseating the CPU. Check, if all the pins on the bottom of the CPU are straight.

 

What do you mean by "reseating" the CPU ?
A twisted pin can explain the hissing noise ?
