was just curious to hear what the fastest clock speeds someone got from their radeon 8500 .. ive heard with a volt mod someone got the card to almost 380 on the memory.... and I thought mine at 300/300 wasnt bad.
mine is stock though.... anyone else? |

(290.3/292.5) ... blue orb/no sinks
i oc'd it to 300/300 awhile back but crashed during the 5th or 6th 3dmark test i believe. backed it down to this and left it. don't have the patience or time to glue little heat sinks all over it..i don't care. edited: for accuracy

got my Radeon 8500 to a core of 306MHz and a mem of 303Mhz. If I bring the mem any higher the gfx distort, but still not bad. Got memory heatsinks and a ThermalTake heatsink with Arctic Silver III adhesive. Wish I could pump the card harder, would like to try that voltage mod, but I really would rather not break me WORKING Radeon..hehe.

I had mine running at 315/315 for 3 months no prob, till one day 32 out of the 64mb just capped out on me
I RMAd it and I will not OC past my current settings. Funny thing is it worked great even with 32mb ram and I still got over 7300 points with it. Not bad for a card with 32mb

after doing the voltage mod for my Radeon 8500 I got the memory running good up to 325MHz, could of gotten higher but it starts flickering a bit. I couldn't get the pencil lead to stick on the board for the core voltages, but I'll have to find a better way to mark it. Not a bad mod if anyone was interested.

Man I don't know how you guys get your speeds up that high. I got mine at 285/285 and sometimes with the room temps go up I start getting minor artifacts. If I go to 290/290, I have heavy artifacts.
Will adding RAM sinks and a better GPU cooler make those artifacts go away? Ray

Adding ramsinks gave me another 15MHz(30MHz DDR) plus they keep the ram modules nice and cool. They difinitely help, although the Vmod is the ultimate tweak
Also I was able to run the core at 315MHz 24/7 with no issues-with the stock HSF.

if ya have a 64 meg version its not likely to go past 310/310 but the 128's are, they have BGA memory a smaller compact mem that is cooler to run. maybe you just have a bad overclocker a possibility. for this thread i had a radeon 8500 128 core=2V mem=4.02V core-speed=350 mem-speed=350 cooling used= custom fridge cooling( ohh and the custom dont mean poo it was totally gheto) heh

I have a 64 meg version of the 8500 retail. I run it day to day at 300/300 with no voltage mods. I can run at 310/310 stable with very minor arctifacts. I can also run stable at 320/320 with fairly bad arctifacts. It will die above 320. I have some extensive cooling additions on the board. MIke

My stock retail 128mb 8500 does 306/306. Textures get wicked corrupted at 311/311. Since that box takes over 5 minutes to reboot (server), I haven't tried to get the last mhz out of the core and memory

Mines perfectly stable at 310/310.
The memory can make 325 but at that speed theres a few bright red, blue or yellow spots appearing towards the end of a map in CS (30mins). It varies for different apps though. Flickering polygons from the core start at 310 for jk2 but not until 325 for 3dmark2k1. Cooling is a blue orb (lapped) and small blue ramsinks with an 80mm fan on top. Voltages are currently 3.94 ram and 2.11 core. The overclockability with current cooling seems to reach a limit at around 3.9v ram and 1.9v core. This was one of the first 64Mb OEMs has all the ati markings on it. |

325/325 with Corb (arctic alumina epoxy), tweakmoster ramsinks and a pencil mod on Vcore and Vmem. See my sig for some pictures.

I can't get my card pasat 275 core... i run it at 270 (cam at 250). I have yet to do anything to the voltage... but i hope to sometime soon. Probably need to upgrade the stock cooling.
I run my memory at 320 (stock.. no cooling )... fun eh? The chips are 3ns and i have pushed it as far as 335-340 without crashing... i do however get wierd artifacts (but the card still does not crash). I have run several tests of Q3 at 335 at 1024x768x4Xaa and the card performs wonders... other than the artifacts.I actually believe that this is not a heat buildup issue because the artifacts don't change with time. It actually seems to me that there is a problem with the memory interface because i am runing the mem/core more than 50mhz out of sync. In any case i've had my fun... will have more

I use a crystal Orb myself as well as mem heatsinks but you have to be very careful to install the orb correctly. It is not easy to do. If you don't offset it a bit, it will hit on the pci slot socket below it and cause the board not to seat properlay in the AGP socket.
If I Had it to do all over again, I would use a small heat sink and just screw one of those little 40mm Delta fans to it. Same thing I use on my Northbridge. Mike

Hey Yeti,
Your system won't crash if you overclock the video memory, only when you overclock the core itself. The artifacts your getting are from minor heat build up and more, as the same as cpu's go, electron gapping on the copper lines by pushing the memory speeds without increasing their bias voltages. If you do the voltage mod on the memory you'll noticed you'll be able to push the memory much further without getting artifacts. I can push my memory up to 340MHz if I wanted to, but wether the gfx look good is another thing.

![]() I believe you are incorrect. Your computer graphics will simply hang once your memory fails. It does fail. If you have ever worked with one of the older graphics cards... GF2 or TNT2.... or any other card for that matter... you will see that when you push the Memory up to a certain point (and use it intensively) the system will hang. This is not apparent on newer cards because they won't let you push the ram far enough. Your system will "crash". The Graphics card will stop functioning making your system unusable... Your OS will keep going (till it realizes the GC is not responding) and then it'll die on its own. Quote:
In my case, however, i have been able to run the memory on the card at anywhere from 320 to 340 Mhz with artifacts but no eventual failure. I postulate that because there is no eventual failure due to heat the card is not experiencing heat buildup problems. So i have come to believe that, quite reasonably, it is the memory controller's problem that is causing artifacts. I do believe that the controller is integrated into the core and when the memory is running significantly faster than the core speed... there arises an issue. (noise or errors or whatever you want to call it). I do admit that i postulate quite a bit in my theory. I won't refute it , however, until i hear an explanation of the memory system on a Radeon from an ATI engineer... and specifically why this can't be. Of course if you know something to the contrary... i'd love to hear it.

Yeti,
I will agree with you in some sense that if you push the memory too far it could possibly lock up considering some video memory is required for gui operation. But I will dissagree with you on the artifact issue, I've had my core/memory very close in speed and still had artifacts. I've pushed the memory up really high and the artifacts got worse, but no lockup. As far as the older GeForce 2's and such locking up, that was probably more because of inadequate cooling which caused the memory to heat well beyond limits, and also, newer memory is build with a little smaller micron level so it builds up a little less heat, because it uses less biasing. I will also agree with the fact that I doubt it is a heat buildup failure, because the memory doesn't run as hot as the core does. The artifacts being generated is from the fact that the memory is becoming unstable and unreliable, therefore causing the gfx being generated to turn to garble. You drop down the memory speed or increase the memory biasing the artifacts go away. But because the core is the cpu of the video card and therefore cannot function without it, it will lock up if it loses communications on it's buslines. As far as you believing the memory controller is causing the artifacts, because of the memory perhaps running faster then the core which causes an out of sync, could be possible, but actually, I think it would cause the lockups more if the core was running faster then the memory, because the memory couldn't refresh fast enough to keep up with the gpu's data requests. But you're post is very interesting and caused me to think a bit and I wouldn't say I was totally right or that you were totally wrong, but I'm just stating what I've learned in my experience and a little bit of electronic thinking. Please post back, I'd like to see what you've found out.

So far I can keep it at 290.3/290.3 and haven't run into any trouble.
If I try it at 300/300 I get very bad artifacts beginning at the nature scene in 3DM2K1SE. I had it lock up once. Dyre Straits |

Not really up to par with some but my little ATI Built Radeon 8500LELE with 3.6ns Hynix RAM normally 230/230 is now at 275/275
![]() will try to push it further. S1

The highest I have pushed mine so far is 300/315, and that's with stock cooling. I'll push it a bit harder when it isn't bottlenecked by the CPU anymore (Tbird 1GHz).

I just wanna add that overclocking your card is great but dont leave it at overclocked settings all the time. You can, and many people do, kill your gfx cards like that.
