I don't think my problem lies in cooling. I used Arctic Silver, lapped the heatsink and it doesn't get hot to the touch.

Need a voltmod.

Doesnt get hot ? Maybe the cooling device not tounching the core nicely ?

I'm sure it's mounted nicely. As said, I need a voltmod. Anyone knows a pencil mod for it? The one at Adrian's Rojakpot doesn't seem to fit mine.

Just tweaked more of the timings and got an increase of 200 marks in 3DMark2001SE.

Which timing? Ram or the GC ? My D43 have a higher bandwidth at 3-4-4-10. Cas 2.5 wont give any improvement also. I think im hitting the wall already.

Haha, it's my GC timings, I forgot to mention that

As for my computer RAMs, I shoved 3.3v thru my D43s and only could get 2.5-4-3-11 at 240 MHz.

Before:



After:

dun dare to touch much on the timings lar.. scare burns...

Owh, lower Mem clock speeds with loose timing eh ? Nice, but its a bit tricky to do this also. If something happens, you need a pci card to help u.

Amedion : Changing the memory timings wont burn the card in any possible way.

Yeah, when I loosened the timings, I didn't get any overclocking headroom. So decreasing the timings was the only way.

I found a voltmod for my card's GPU, according to Adrian's Rojakpot guide. The voltage regulator in the guide is 1575 PXCR, where as mine is 1575 PYFL. Should have the same specifications, will try out in 5 minutes.

I don't know where to measure the voltage, so I'm just going have to blindly try and see if I get anymore overclocking gains.

Voltmod was a success. Running my core at 541MHz now, and testing for higher as we speak.

During the first time, I didn't know how much I was supposed to pencil, so I just scribbled lines at the voltage controller package and legs. When I switched on my PC, garbage started lining up on my monitor. I switched off my computer, removed the graphite and made only two lines... that did the trick.

I benchmarked the card at 530MHz Core and 175 Mem, (my Core used to be 486MHz, Mem the same) and I only got improvements in 3DMark03 by 70 points. Seems that my video card is bandwidth limited.

Doing the voltmod also increased overclocking headroom for my memory. Initially from 168 MHz it went up to 183 MHz. Perhaps a chance to test for loosened memory timings?

Still conducting tests, full results will be out later.

I think if u loosened it too much it would decrease the marks too. 9600 is a bit tricky to overclock but once u did it, its a relieve.

Got any success with AtiTool ? They got built in feature that disable the 9600 protection stuff.

I didn't use AtiTool's anti-overclocking feature. The BIOS that I flashed to my video card is already overclocking-friendly.

After all the tests, I could only squeeze in another 150 marks to 3DMark03.

I need a voltmod for the memory chips.

Owh, Anti Protection removed. Nice one, ensure u have a proper cooling before cranking the voltages.

no experience at all.. dunno wat u both toking about.. i oni know how to use atitool to oc.. haha

Haha, you can ask me and uzairi if you have any overclocking problems. Of course, uzairi is much more experienced.

Still searching for a TSOP voltmod.

Edit: Anyone knows what's a multiplexer/demultiplexer?

I try to help you guys whenever i can. Make sure u have the proper cooling before attempting any voltage mods tho. Get some ramsink for your TSOP rams yah colin ? You wouldnt want it to fry do you ?

OOT : multiplexer/demultiplexer ? Learned that but forget already.

I don't think any voltage controlling is related to the multiplexer/demultiplexer. I can't seem to find the IC that controls the voltage distribution to the memory chips.

Google-ed already ? I think you can find it there. Here i attached some of it.

For Ati Reference Card

For Gecube, Gigabyte Card
http://www.rojakpot.com/showarticle.aspx?artno=116&pgno=0

Yeah, I got my voltmods from that. The Gecube GPU voltmod works with my card, but I can't find any IC that's related to controlling the Vmem.

use omega driver guyz.. u'll get a better result..
here my 96pro result last 2years..

Wow, that's a great score. Is that RAM at your overclocking program at DDR speed or at normal speed?
