Do you want to enhance your RADEON performance?..

Az7 · Sep 4, 2003, 02:05 AM

Hi,

Try this :-

Registry editor , Goto this location :-

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\PriorityControl

If not exist make new one,

then

Add this DWORD entry :-

IRQxxPriority and give it a value of 1

where xx is the IRQ# of your nice Radeon.

I hope this tweak enhance your Radeon's performance

The_Neon_Cowboy · Sep 4, 2003, 02:50 AM

It better to set XX to the irq of your real time clock usually irq 8

Setting to your video card boosts your video score a little but the proper tweak is the real time clock because it will improve the total systems performance

And don’t set more than 1 or 2 because it will cause issues

jeuda · Sep 4, 2003, 03:15 AM

yeap, realtime clock is IRQ 8 on my Winxp. Not sure what it will do. Trying now

jeuda · Sep 4, 2003, 03:16 AM

Just checked, Radeon is IRQ11 on my system

THIS TWEAK IS DOES NOT WORK

This tweak can increase the priority given to any IRQ number, improving the performance of that component. The most common component this tweak is used for is the System CMOS/real time clock, which improves performance across the board go to :

Really? Then why did I Gain 100-200 3dmarks from doing it??? on several systems!

alambaker · Sep 17, 2003, 12:20 AM

i have never ever messed with my pc registry, im a newbie into this graphic things

i checked and the value was 2, should i change it to 8????

Senior Citizen · Sep 17, 2003, 02:44 AM

Change it to 8 ? If you do not know what you are doing in the regestry leave it alone. The registry is not a poke and hope program (hope it works).

Hkhalid · Sep 17, 2003, 08:49 AM

nice performance enhancing tip i can say

~~Crash Override~~ · Sep 17, 2003, 09:55 AM

real time clock just has to do with updating the bios clock to match the windows clock in real time IIRC.

So why would that make the system faster?

BWX · Sep 17, 2003, 11:04 AM

You can do this with X-Setup too.

Gurm · Sep 17, 2003, 01:50 PM

Now what if your machine doesn't USE IRQ's? Hmm? What if you're in ACPI mode (as most of us are, I daresay)? My video card is on IRQ 212. That's not a real IRQ. Dumbass.

Judas · Sep 17, 2003, 02:04 PM

Odd, isn't that somehow a way of actually changing it so that is stuck and suited.... for the exact time...... you can adjust the clock so that seconds pass very quickly...which would give you a terrible score.... or pass slowly...give you an amazing score... or totally out of the world score...... i remember a program you could get to be able to do it....

Kgentatszu] · Sep 17, 2003, 02:12 PM

i'm a NOOB here! please explain more, how does this thing work and how do i do it?? i dont really understand the above posts.....thankz in advance..

I only have IRQ's up to 22 and my Radeon is on 16. Tell me what you are talking about saying IRQ 212?

You must have made a typo which doesnt help your case of calling someone a dumbass, yet leaving a simple mistake like that behind.

ya why question someone else's post when you are making as many errors in your post, might it be an id10t error perhaps

Kgentatszu] · Sep 17, 2003, 03:04 PM

my radeon is located at IRQ 16 too, so what do i do next???

It's all about system priority...
Because you bios is @ the the same IRQ meaning any calls to the bios will have priority over all others (meaning it gets all the CPU time and memory it wants when and however it wants it, it doesn't have to wait for any other component it's got first dibs. Meaning more performance in those devices resulting in a higher 3dmark scores.... ARG it's hard to explain without getting down to the specifics of computers... I'm not righting a 10 page course to day ...

Imagine a row of components asking for cpu time.
imagine as if these components were solders and the all have even ranks as privates so there requests are on a first come first sever basis and limited to free available resources at the time. And, they were all given IRQ numbers.
imagine one of these soldiers was promoted to . (bios IRQ 8)
when the general ask for something he gets now it no mater what place in line he, and is not limited by only free resources @ the time is because he has priority over the privates requests if he wants all the time he gets it.

so basically you giving you bios and video card priority over say a request from you sound or modem or lan.. It results is faster response times form the prioritized components. this works fine but if you specify more than 2 you'll start running into issues. ( An army of all one star generals would get nowhere)

(this tweak works on all video cards!!!!!!!) as long as your running WINDOWS XP

Maxxypoos run 3dmark get your score go to

Registry editor , Goto this location :

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\PriorityControl

Add this DWORD entry :-

IRQ16Priority

and give it a value of 1

reboot and run 3dmark again tell us your scores..... before and after...

My 9700pro is on IRQ 16 also. But I made that registry entry and used IRQ 8- the system timer, my system seems overall snappier- I'll have to check 3dmark.. I think you can give more than one IRQ priority, I think you can give the video card IRQ and the system timer/bios the same priority- higher than all others.

I know you can do it in X-setup, but I'm not sure if it uses the exact registry entry shown above, I'll have to find out.

Anyway, I was wondering if I wrote IRQ08Priority (which I did) if that was correct, or should I just write IRQ8Priority without the "0" before the "8"- does anyone know? Thanks..

Gurm · Sep 17, 2003, 05:37 PM

Don't go calling me an idiot.

SMP machines use "IRQ's" up to and including 255.

Single processor machines will rarely get above 32.

But both numbers are "fake". The standard programmable interrupt controller on your system board only goes up to 15. The fact that yours is on 16 indicates that you're in ACPI mode, and in Windows XP that means your machine is not using interrupts at all! Rather, it's doing "hardware polling" which is a much more advanced and efficient (albeit slightly lower performing, in the range of 1-5% systemwide) system.

So this change will do NOTHING. No priority is given to devices, they only have "IRQ" numbers assigned for the sake of compatibility.

On Win98 this may help. If you FORCE installed with "Standard PC" instead of "ACPI PC" then it might help. But as-is any benefit you're getting is for some other unrelated reason, or else this setting doesn't REALLY do what you're saying it does.

DON'T accuse someone of being an idiot until you're sure they have no idea what they're talking about. I know my shit.

So who is this flame directed to anyway? And is it really necessary?

Kgentatszu] · Sep 17, 2003, 06:06 PM

i think Gurm has some point there cause if i'm not wrong, i did set an option to ACPI mode........anyway, no harm trying, can someone tell me where is this registry editor located???

Somebody answer this please

edit: well i have tested both tweaks IRQ08Priority or IRQ8Priority and IRQ19Priority (radeon´s): NO 3dmark03 performance bost for me (~4520).
