OCing the Parhelia yet??????

[Fenrir(AVA)]

If they do put a card that is clocked higher, I will buy one in the drop of a hat. Especially if it is clocked at 300mhz.

Isn't it true that if you occupy the AGP slot with a video card, that the PCI slot directly below PCI #1 is pretty much useless since the AGP and PCI #1 slots share the same IRQ?

I mean heck, I have 3 or 4 PCI cards in my PC, but not a single one is directly below the AGP slot because I thought the above is true. Can someone verify/confirm this to be true?

Because if it is, I don't think that the size of the heat-sink/fan/cooler is of that much concern (which is a good thing for me) as I would rip off the stock HSF and put on a 3rd party one in a heartbeat if that were true.

maybe a die shrink will come faster.

does anyone know if 3dmark really uses the 4 texture units?

and how many vertex/pixelshaders does it use, because the GF4 has only 1 pixelshader , its faster the parhelia's 4 (if they are used)

DMA settigns really fix all IRQ problems in WinXP.

It depends on the motherboard vendor and how they routed the PCI interrupt lines. They can do it how ever they want to.

But usually it is the case that they will share the same PCI interrupt.

Check with your mohterboad manual as that usually indicates which slots use what PCI interrupts.

yeah was reading an article off some gf4 card and is was the same setup as the Parhelia no heatsink on the memo and a core same blower a Parhelia

so gf4 -------------- vs------ Parhelia

gpu(mhz) 275 ----------------------- 220
memo 550 ----------------------- 550

overkocked shit with heatsink ectra beter cooling gpu

so gf4 -------------- vs ---- Parhelia (hopefuly hehe)

gpu(mhz) 340 ------------------------ 285
memo 710 ------------------------ 710


okay there was a voltagemod but that wil come on the parhelia to but memory is faster its 3.3ns so i would go higher so that would gif some good fps i think hehe


ok i am a dreamer maybe but i hope the best for my self when i got one at home heheh

[Fenrir(AVA)]

Lets hope we could get those overclocked specs on the Parhelia, just need to find a heatsink that will fit the card, and be efficent.

Well, I brought home that crystal cooler today.
There's no way it would work on Parhelia. mounting pins on P are just too far apart.

Fits my G400 nicely though

a core/mem of 230 / 305(610)


yeah sounds good to me hehee

OMG that's ridiculous. Whatever you are trying to say thanks for the laugh Ozzie, no offense intended.

[frankymail]

Kruzin: if you want, you can send me your Parhelia (no jokes, i'D provide you with full address and personnal info), I'd modify it and UPS it back to you in a matter of hours. If I was to break it, I'd send the broken one back to you rightaway AND I'd sent you mine when it gets here... (just to show you I wouldn't get a fur tree out of your -ss) After all, I did win $1000 from Intel for my science fair project with a nice certificate saying: "This award was attributed to Francis ********** for is innovative way of cooling a Pentium processor and increase its performance" (yeah, I know that was 6 years ago and I was still in senior high... but that was still phase-change cooling ).

And that would be free of charge (just the cost of shipping it my way).

Have you tried to push the OC level on your G400 with the CrystalOrb? Get a better result or the same?

[knirfie]

watercooled all the way, my processor already is

[RedRed]

The coling will be sorted, what about the software and the Voltage mods required for this? where is the source for these going to come from, if not Matrox. There isnt a snowball chance in hell that any voltage mod will come from Matrox....

[Cheesekeeper]

There are lots of instructions on the web for voltage mods for Geforce cards, and I'm pretty sure that none of them came from NVidia. Using those procedures as a base, tweaking the Parhelia should be easy, for anyone with decent electronics knowledge. My electronics knowledge isn't that great, but give me a half hour alone with a Parhelia and a multimeter, and I'm sure I could track down which rail needs to be boosted.......

Maybe a Crystal Orb would work. I'm no cooling expert.
It would fit, but one of the hole would have to me modified.

There are some kits on that site that might work that include RAM sinks...

Subject: Parhelia cooling...


I know that the card is as yet not shipping. All the same I was curious
if you have been following its development, and if you have any plans to
look into a cooling solution for these Matrox Cards?


Here is the interesting info... the shipping card is clocked at 220MHz
core, which is much below theoretical limits. Apparently the AGP spec
forced a smaller heatsink onto the cards, and forced Matrox to downclock
for stability...

Some at Matrox (Haig at tech support) have implicitly said that an
improved cooling solution will allow for increased clock. I surmise
that given the untapped memory bandwidth, changes in core clock should
yield excellent improvements in performance.

In any case, many of us over at the Matrox Users forums are excited
about the posiblities of overclocking, and would be very intersted in a
quality, custum fit solution.

Thank you for your time...
Dr. Charles Moreau


I have been following it, and especially any articles showing closeups of the card itself. As soon as I can get some measurements of the areas around the memory and GPU, I will put together a cooling kit for it. As for overclocking, no idea till someone actually gets one and tries it...
