3.4Ghz EE swap for my 8890 - Page 2

I love this thread ~ thanks for starting such a monster... I've been wondering about such an upgrade for a while

I do a lot of 3d work (rendering at 100% cpu usage for hours on end!) and I bought an 8890 in the fall of '03 with the 3.2 p4 and am looking for a processor upgrade. My machine is already loud as hell (yes, I've cleaned the hsf) so I don't want to go putting an even hotter processor into a system that sounds like a hair dryer... anyway, to the point:

If I plug a 3.4ee into my 8890, can I put a passive skt 478 heasink on the processor. This thing obviously won't move once the hsf is installed and I've already designed a table that will accept a large heatsink sticking out of the bottom of my lappy so that's a non-issue at this point! I'm just wondering if anyone's done this before and what type of results it produced... hopefully lower temps and maybe quiter operation?! The primary concerns for selection of a HSF is the clearance from the top of the processor to the outside of the case... basically, the HSF needs to "lift" itself out of the processor bay and away from the case for the situation to be ideal. It looks like a heat-pipe setup would be best for this.

what passive hsf's would you recommend?

Can I use a directional active hsf and somehow run the fan from the 8890's mobo and blow the hot air from left to right?

hkancyr,
could I ask a huge favor of you and get you to run this benchmark. I'm mostly interested in the 3.4's ability to render cg stuff and this benchie tests exactly that!

CHEERS!

tekton3d you mention your 8890 is loud.
You may not know about a very simple mod that makes it quiet as.
The sound is due to resonance between the internal memory fan (under the keyboard) and the mobo.
Check this thread:

Both my 8890's are no louder than a normal laptop
I still have some of the material referred to in that thread.

Thanks, I'll check it out : )

That mod is definitely on my list to do for tomorrow! Hard to belive I've used this thing for almost 3 years and suffered through that damn wine thinking it was incurable!

someone mentioned ram heatsinks in that thread ... which types can be used for the 8890?!. . . Any type that is fastened via adhesive?

I'd like to know how to do this also! . . . that FireGL would be most welcome in my 3D viewports : )


Many thanks!

You will not need the RAM heatsinks.
A few of us are running 2GB in our 8890's without any heat issues.

If you need some of the material just send me an email or pm with your address.

Yeah, I forgot how little room there is under the keyboard... surely not enough for 6mm of heatsink!

That's good to know, because 2gb is looking pretty good...

it does have to be 200 pin ddr400 pc3200 ~ right?

So now I'm curious tekton3d... What are your results in CINEBENCH 9.5? How about SPECviewperf 8.1?

I'll get those #'s to you as soon as possible ~ I've reformatted and am now re-installing programs, drivers, etc!

I've not had the chance to upgrade anything yet! So my results will be pretty standard, nonetheless I'd still like to see them myself to have some numbers to compare against when I upgrade components : )

inconel, could you share more about how you did your video card mod? I know there are a lot of folks here that are more than interested in such an awesome upgrade!

Thanks

Thanks!!

thanks for the update!

Man, I haven't had a chance to update this thread with my thesis deadline approaching !!

Anyway, thanks for posting your scores hkancyr. I'm working from my dual opteron workstation right now and will get my 8890 3.2ghz scores posted in a short while.

interesting: hkancyr's 3.4 P4 outrendered my Opteron 248 machine in single CPU ... still impressive for a laptop : )

CHEERS!

Wait - I found a text file with the old Cinebench scores:

CINEBENCH 9.5
************************************************** **

Tester : tekton3d

Processor : P4 800fsb 512 cache
MHz : 3.2
Number of CPUs : 2
Operating System : xp pro

Graphics Card : radeon 9600 mobility
Resolution : <fill this out>
Color Depth : <fill this out>

************************************************** **

Rendering (Single CPU): 305 CB-CPU
Rendering (Multiple CPU): 352 CB-CPU

Shading (OpenGL Software Lighting) : 1301 CB-GFX
Shading (OpenGL Hardware Lighting) : 2561 CB-GFX

OpenGL Speedup: 7.85

it looks like for rendering only, the 3.4 may not be worth the trouble and cost of upgrading for me. I may put that money towards a pair of 256 Opterons and add another 74gb Raptor in RAID 0 for programs and OS for my primary workstation.

Thanks for the update tekton3d.

There is an adapter to allow a pentium-m to work in a pentium4 socket (with an 865 or 875 chipset) but it's only for a couple of Asus desktop motherboards. Even if it worked with any p4 motherboard, it wouldn't be much use for a laptop because the stock cooling system wouldn't work. It doesn't have hyperthreading anyway so it sounds like you're better off with the P4 as you've mentioned earlier you prefer the responsiveness HT brings.
