You wanna' take that Radeon card HIGHER??? Check out the below link for a GREAT article for VOLTMOODING your card. The article is complete with pictures and is VERY informative.

I included email correspondence that I received from the author in response to my NOOB questions. It's GREAT when someone stands behind their work by taking time to respond to emails as this author did...THANKYOU! And THANKYOU for such an INFORMATIVE article. I found the RESPONSES as helpful as the article and so asked the author's permission to post them.

QUERY
Subject: Radeon 9800 Voltmod Guide

Wow...this is some article!!!
I am a bit unsure about a few things...

1) This VOLTMOD allows for more voltage to both the RAM and GPU, correct? or just the gpu?
2) I have been told that the software (games) frames per second will max out because the software does not allow it to take advantage of your phenomenal graphics card speed...is this correct? Or will I see an increase in the game's fps EACH time the graphics card is increased...up to infinity (for example)?
3) My Radeon 9700 non pro runs at 351/303 with air cooling...of course, I've got a VANTEC TORNADO 80 mm fan blowing 84 cfm of air right on it...smiles.
4) What are your thoughts on OVERCLOCKING the AGP bus individually or in conjunction with overclocking the gpu and vram?

Hello,

1) This VOLTMOD allows for more voltage to both the RAM and GPU, correct? or just the gpu?
Yes, it allows you to regulate how many more volts the RAM and GPU of the video card are getting.

2) I have been told that the software (games) frames per second will max out because the software does not allow it to take advantage of your phenomenal graphics card speed...is this correct? Or will I see an increase in the game's fps EACH time the graphics card is increased...up to infinity (for example)?
In some games, such as Half Life and Counter-Strike, you have FPS limiters, where the FPS will not go higher than a certain number. However, the drops in FPS in games like these will not be as noticable, as your video card is clocked higher. More volts to the GPU and RAM does not make it faster. It just allows you to make it faster by upping the MHz rating on the RAM and GPU. You will notice in other games higher FPS when this has been done. If you are running Vsync, same applies for games that have FPS limiters.

3) My Radeon 9700 non pro runs at 351/303 with air cooling...of course, I've got a VANTEC TORNADO 80 mm fan blowing 84 cfm of air right on it...smiles.

That is a nice GPU clock speed for that card. However, I feel you could get more out of it, by getting a bigger heatsink to compliment that Vantec Tornado. The GPU and VDD volt mods for this card are virtually the same, however you'd have to use the chips themselves (SC1175 and the ISL6522), same pins used.

4) What are your thoughts on OVERCLOCKING the AGP bus individually or in conjunction with overclocking the gpu and vram?

Overclocking the AGP bus is pointless in day to day systems. I do not recommend increasing the AGP bus as the benefit is never seen in games. For benchmarks, such as 3dmark2001, I've noticed SMALL point increases from it. Same goes for increasing the AGP Voltage. I believe it's uncessary overclocking to this, and it often causes more problems than good. Some users have damaged their video card and/or motherboard by overclocking the AGP bus too much, and/or increasing the AGP Voltage.

Thank you,

Query
The card runs stable at 379/303...I just put a safety margin of about 30 mhz. If I up the RAM to 310, then I get artifacts...I would probably benefit from RAM SINKS more than gpu sink or do I simply need to increase the voltage to the RAM? I can increase voltage for the gpu in my nForce2 bios, but not to the ram...this is where your volt mod comes into play, huh? I could voltmod RAM only right?

Response
You would benefit more from increasing the voltage to the RAM instead of ramsinks. You cannot increase voltage to your gpu via the nforce2 bios, that increases voltage to the AGP bus, which in our last email is this:


The gpu and memory volt mod come into play when you run into artifacting, where cooling and extra volts both help. However, you need to find out yourself what is more necessary, be it cooling or voltage. Every video card is different, so your video card will respond differently to extra cooling and volts than smoeone else's.

QUERY
The card's stock speed of 276.75/270.25 has a difference of 6.5 mhz (276.75-270.25=6.5). At first I strove to maintain this difference/ratio since I thought this speed difference was chosen by ATI for a particular reason...like; most compatible ratio for gpu to ram speed (ie similar to overclock dividers found on motherboards) but I found that it made no difference.

RESPONSE
The difference between the GPU and Memory clock speeds doesn't matter. However, after a certain distance apart, one starts bottlenecking the other. This is seen in 3dmark2001. After upping the GPU so much over your ram, you'll see that the increase in fps is becoming smaller.

HOLY cow! that is pretty cool

I would do it if you could do it to the ALL-IN-WONDER the bottoms look differnent

JackFrostyCPU

i didnt know that they auto censored thats kool

JackFrostyCPU

Only a matter of time befoer they tag me for my icon

TAG! NEGATIVE 50 REP POINTS! YOURE **IT! - QUACK QUACK

Try using the edit button, either that, or use that big friggin melon BEFORE posting.

Nice info BTW jazz.....I might have to give that a shot in a few months.

Just like O/Cing your CPU...
You first need Extreme cooling, clock it up, and add voltage as nesassary...You might want to inquire about the quality of the
15-OHM/15-WATT variable resistor used, and possibly his source for this Item...I had little luck finding this part under 30Bux. Not really sure if one should trust a $4.99 radio-squack quality, part for 300 bux worth of grafx card.
Nice to see him respond, like he did. A bro about his craft, KUDOS


JackoffstyCPU, you might want to re-read the forum rules...good info there. I bet the under 50 post for a custom avitar rule applies as well.
Just a little hint, to make participation here a bit better.

RESPOND is just what the man did!

"I am not sure about the 15OHm/15 Watt variable resistor you are speaking of, but the 10kO 0.75W 15-Turn trimmers I linked too are good quality. I was skeptical at first if the fluctuation was bad, but I've used these many times now, with no problems. I have always been for fixed resistors, but these are just as good in my opinion. Also, Radio Shack soldering irons can be had for <$10, and are suitable. I like using the 15W model and occasionally the 25W for applications where more heat is needed.

Thanks for the kind words "

I got this in email.

Awsoem find.. Great info..
