Sorry for the wait Nitz. I was doing a 72 hour burn in test with Doom 3 and … well … ended up doing a 10 day burn in if you know what I mean.
I had to lower my clock -15MHZ from the speed I previously posted as it started getting up into the 90C range, which I don’t like. The -15 MHz on the core ended up making my Geforce FX5650 run at 88C tops. I also clocked the memory -11MHz lower due to long term stability issues. All of my tests and over clocking are done with both fans on HIGH (CPU and GPU) and a laptop cooling stand I bought from newegg.com. In the Doom 3 time demo (MED Quality sort of ... alot of customization via the console) I was able to average about 41FPS at 1024 x 768 (I also heavily tweaked out the Doom3 engine. (Here is a guide with a slew of great console tweaks… but there are many many more if you search for them http://www.tweakguides.com/Doom3_8.html
As you requested here are some 3DMark scores.
Geforce FX5650 @ 370 Core / 691 Mem:
3DMark 2001: 10,112
3DMark 2003: 2,993 (I will find away to pass 3000!
Geforce FX5650 @ Default Core / Mem:
3DMark 2001: 9,597
3DMark 2003: 2,542
Once I’m 100% positive that my V.RAM cooling mod works and was beneficial I will post the procedures. For now, here is a brief overview of what I did.
1.Cut the GPU Heat sink / Heat pipe from V.RAM Section as state in my previous posts.
2.Used GM’s copper V.RAM plate and Artic Silver 5 in place of Dell’s blue thermal pad. (This caused the thin aluminum assembly to act as a big heat spreader. GM’s copper plate helped to provide a better medium for the heat to be transferred from the V.RAM to the aluminum assembly directly above it.)
3.Did the GPU heat mod (with the copper plate & lapping & AS5).
4.My solution to help prevent the GPU heat from traveling to the MB chipset was to remove Dell’s blue thermal pad entirely and leave an air gap between GPU heat sink/pipe assembly. I may figure out a mod for this if the MB chipset temperature proves to be a limiting factor.
5.Used a soldering gun (an iron would have taken way to long) to fill in the where the heat pipe had been pressed or wielded on. (My original Geforce 4 4200 came with this already done, but not my New Geforce FX 5650.)
6.Made the GPU fan hole bigger for better air flow. (I used a dremel and got it to come out extremely well, especially when accented with 2 blue LEDs.)
7.** Added some thermal probes to make help make sure I wasn’t frying anything. I placed probes on my Motherboard chipset diode & heat sink, V.RAM (There were two sets of V.RAM) diodes and heat spreader.
Again, I’ll post more information when I am certain that everything works as expected.
Oh, and Doom 3 is a GREAT game! Don’t waste your time playing it during the day though. You have to play the game in the dark with some bomb headphones. I use Sony DJ V700’s. . . . Wow
