is 10303 a good score for a amd 2600+ with gf4 ti-4200 128mb 8xagp and 512 pc3200 ddr ram? everything is at stock speeds

[therealwesty]

Stock speeds? Overclock that puppy and see what you can really do!<BR><BR>Sounds pretty good though... my system does about 8500 at stock speeds and you have an edge in both CPU and video card power.

[caffeine]

ive tried, any time i have turned the speed up it wont boot

[therealwesty]

What are your specs? If you post you videocard, CPU, motherboard, RAM and any cooling hardware you may get some advice about the overclock.

[caffeine]

well i posted all of that except for my asus a7n8x delux mobo and i have a hdd fan in the front and a side fan

[therealwesty]

You should be able to get a great OC with that stuff. I too have the Asus A7N8X and PC3200 RAM... I was able to get my AthlonXP 2000 up to 2255 (12.5 x 180 = 2255). I was also able to run 200 FSB no problem as well (11 x 200 = 2200). Don't be afraid to increase your voltage to the CPU a bit. I had to run 1.775v on the CPU to acheive my overclocks.

[caffeine]

what exactly do i turn up in the bios? maybe im turning up the wrong thing?

[therealwesty]

You'll want to increase the FSB speed. The detected FSB speed for your 2600 would probobly be 166MHz.<BR><BR>My usual process...<BR><BR>1. In the BIOS increase the FSB speed about 2 MHz... 5MHz if you are feeling lucky.<BR>2. Boot up and run 3DMark2001 or Prime95 through about 25 revolutions - if you can do this it's stable.<BR>3. Restart and increase a few more MHz<BR><BR>If at some point Prime95 or 3DMark crap out you may be unstable. The options at this point are to back off a few MHz (pehaps to your last successful speed) or to increase the CPU voltage one notch (usually 0.025v) and boot and check for stability again. If you opt to increase the voltage and it still craps out, I try one more notch on the voltage before I give up and go back to the last successful speed.<BR><BR>Using the A7N8X Mobo and PC3200 your mobo/RAM will support at least 200FSB. So after you have determined a maximum speed for your CPU doing the above process you should try to lower the multiplier to so you can get that 200FSB.<BR>For Example:<BR><BR>I maxed out at 2255 MHz (12.5 x 180FSB = 2255 MHz)<BR>So 2255/200 = 11.25 so set the multiplier to 11 -> 11 x 200 = 2200 MHz, pretty close to max speed.<BR>You should be able to boot and run the tests here.. if not try to increase the voltage another 0.025v.<BR>Because I just won't quite... I continue to try to increase the FSB again and see what I can eek out of it.<BR><BR>As you increase the FSB though, your AGP frequency will increase... If the AGP increases to much the AGP bus will become unstable before the CPU or chipset is and crap out your OC prematurly. I know the A7N8X has AGP locking... you can set the AGP frequency maually or the 'auto' function will prevent that from going to high. It may be a good idea to determine the AGP max frequency by OCing it alone. That is with everything else at stock speed, raise the FSB frequency and test it... do this until it craps out,you can also raise the voltage for just the AGP to gain stability.<BR><BR>To OC the video card... download a program! PowerStrip is my pick. Go through similar process increaseing the GPU core and memory speeds.<BR><BR>GOOD LUCK!

[therealwesty]

P.S. This process was learned in this forum... largly from Colin, Shiznit, Ginsu and rithemking and the rest of the gang... adapted slighly by me of course. And yes I said Colin... he actually replied to a few of my threads!<BR><BR>Just putting the credit where it is due. <img src="i/expressions/face-icon-small-wink.gif" border="0">

[Ginsu543]

Hey therealwesty,<BR><BR>Doesn't your Asus board have AGP lockout? Most nForce2 boards allow you to change AGP and PCI frequencies independent of the FSB through BIOS.

[therealwesty]

Yes my board does have AGP lockout. I think I explained it in the long bit above. You can set the AGP fequency manually or set it to Auto... I think Auto just reads the required frequency from the graphics card.

[caffeine]

westy, do you have aim? it would be easier to talk about it over that sincei ts just me and you talking<BR>

[caffeine]

11259 with 200fsb x 11

[therealwesty]

Sorry man no AIM... I am at work most of the time I have been replying here, so no chat stuff at all.<BR><BR>GREAT JOB with the OC. 11256 is where you should be with that machine!<BR><BR>Note that I don't run that fast all the time... I usually just OC to try to get a high score. I run stock speeds some of the time. When I feel like I want more performance gaming I usually run 12.5x166 = 2088MHz. A good rule is to find your top OC and then back of 5 MHz or so and run that normally.

[caffeine]

how do you go up or down 2-5? mines got presets of 166 then 200, nothing in between

[caffeine]

so i had to just set the fsb at 200 and took the multiplier down to like 9 something and slowly took it up til 11 was the highest i could boot at

[therealwesty]

In the Advanced Chipset features... for the system Performance I beleive there is a 'System Performance' option. This can be set to Optimal, Aggressive, or User Defined. Setting it to User Defines will let you change the FSB one MegaHertz at a time.<BR><BR>On the Advanced Chipset feature I have everything possible set to User Defined to so I can fine tune everything.

[Ginsu543]

Caffeine,<BR><BR>11 x 200 is a very good oc. A good overclockable nForce2 board like your A7N8X Deluxe with PC3200 ram should be set at 200 MHz, minimum. As therealwesty suggested, I'd try upping the FSB 1 MHz at a time and see how high you can push it. It depends on the quality of your ram and the overclockability of your processor.<BR><BR>Just to give you some point of comparison, I run similar hardware (take a look at my sig). I have my 1700+ oc'd @ 11 x 200 = 2.2 GHz and I also have a Ti4200 128 MB 8x AGP. The highest I've been able to reach at 3DMark2001SE is 14156 (with all the background software I run, I usually get high 13000s). If you want to max out your score, turn off all background programs. Also, are you running dual channel on your ram? Dual channel helped me raise my score. Another thing is to raise the AGP voltage (I raised mine from stock 1.5V to 1.6V) and overclock the graphics card. I used Coolbits to overclock my GPU/RAM to 295/575 MHz. Finally, try raising the AGP frquency from stock 66 MHz to 70~80 MHz (try out different values).

[TranceJunkieXL]

I agree with Ginsu caffeine. Using the Coolbits hack to increase your VC clock speed will have the most significant impact on 3DMark bench scores. I got my Ti4200 64MB up to 15.4K using that and a clean install of Win2000Pro. <img src="i/expressions/face-icon-small-smile.gif" border="0">
