Can Overclocking a CPU without overclocking the AGP bus or Video card Cause Artifacting?
Highly doubt it.
well the Vid card cooler is fully on, stock unit, not overclocked, i have excellent airflow thru the case.
i think i got it before, with my socket a system. and yes, the vga card im using atm is never overclocked. but the problem went away with my current setup now.
Only time i've seen that when nothing is OC'd was on a factory OC'd 7900gs OC. It artifacted all the time (even in BIOS).
Ended up having to replace the GFX card, but thankfully it was still under newegg RMA warranty period.
Sounds like you should RMA it...
Well if you oc your system and dont lock you cpu:agpci clock to 66mhz i could see that being an issue because in theory you overclocking the whole agp bus .
I also had a His IceQ 3 1950pro 512 agp that would constantly lock up to a black screen or artifact till crash under normal temps and clocks.
If i where you id rma it and get the gecube 1950xt or an nvidia card if you want less headaches
^ But I had the same problem with my PC X1950 (with Accelero X2), I'm glad the problem went away now.
P/S: Maybe these X1950 AGPs have something to do with Socket A based mobos?
what cats are you using?
yes. if the model/texture data gets corrupted on the way from disk->memory->cpu->bus->vga card you will see that.
well there is a possible chance the card maybe damaged, as i opened the case recently then i noticed a PLL Heatsink sitting ontop of it, I had originally set it in there to see how much coverage the PLL sing would have on different components, I forgot about it and stood case back up after doing a CPU swap/system cleanout, the sink was sitting on the card. I noticed the artifacting after getting to the range of 2.33GHz in Microsoft Motocross Madness 2, whats odd is i see no apparent artifacting in UT2004. I recently made a video of MCM2 using Fraps which i noticed artifacting at the rear tire of the bike, during frame 5-6 in WMP, which i did see in game. To make note the pll sink has its original TIM on it which i guess is from 3M. the sink was standing up on the card.
failing system memory can cause all kinds of trouble, video card restarts are one of them. video corruption is another...
Ram is designed to run at 500 MHz (250) so its not that, if system was failing it would have BSOD by then. Also you should read my previous post. Im also talking to the other geeks on MSN about it.
Yeah, if you push the CPU or ram or mobo too far without enough power. It's just like if you overclock the gpu to far. Just that artifacting is defiantly more noticeable when you push a gpu too far compared to a cpu, ram or mobo. Just remember, the cpu renders the 3-d image, the graphics card takes it from 3d to 2d. So if you cpu renders a bad 3d image, the graphics can't do it. Or if the ram doesn't store the 3d image right. Or if the nb doesn't transfer the 3d image from one place to another correctly.
i've had ram that would pass 24 hours of memtest86+ but would cause all kinds of havok. if you are running vista try the built in system checker, when it starts hit esc and select advanced.
I know that if I OC my RAM too far the system will randomly turn off.
//It IS possible for a CPU to artifact, there was a guy on here a while ago who had a PD clocked at 4GHz with stock volts, and the letters were sideways, an E might look like it was flipped 90 degrees to the left to make it seem like it was laying on it's side. Overvolting fixed the issue. He was encouraged to get better cooling.
so your saying Thermalright SI-97 is not enough for the CPU? Anywhich way i duped the problem and its the card, as i lowered the clocks on the CPU, didnt have any affect, So im requesting RMA from HIS, i should be able to ship off next week, hope i get a brand new X1950 Pro 512 AGP From them.
if its a barton 2500 id say no
i never had gfx ishews with my 3000+ barton it would just crash
newer cpu.s yes cus the chip set is in the cpu
could be your north brige chip set getting hot that will do it
you dont usualy see what happens when everything fucks up with a socket A cos they will just restart you computer, well my Duron 1800, Athlon XP 1800+, 2500+ and 3000+ did that anyway. So i can't see it causing any artifacts with the grafix because your pc usualy just resets.
