Radeon 7200 32mb @ 500mhz core :)

[morgash]

ok so here is the story. I went to Radio Shack today and bought a $10 Athlon XP heatsink and some superglue. I then came home and proceded to superglue the Athlon XP sink adn fan to the Radeon 7200 GPU. After this was done, i opened up ATI tool and started the OC. After going up in 10 mhz increments for quite some time and letting ATI tool scan for arts i finally reached 500mhz with the HSF at room temp and no arts for over 10 minutes. Pretty impressive OC considering the stock core on this card is 165mhz lol. Not seeing heavy performance gains of course since the RAM cant scale with it. so thr gpu is just sittin there, waitin on the slow ass ram to get the image to fit i had to save it as 256 colors cuz imageshack is teh suck. so, without further ado, HERE is the pic to prove it
lemme know whactha think

*EDIT* ok so seeing the potential for improvement and fun here i took the stock HSF off the geforce 5700 ultra last night and am gonna test it with an all copper 45CFM Socket A HSF that i superglued on last night. I am also gonna use a bunch of really small HSF's from older vid cards to actively cool every 2 RAM chips. Let ya know how it goes tonight.

*EDIT2* Ok update on the Radeon. I currently have it sittin pretty at 550mhz core. That seems about the extent of its abilities.

run 3dmark


thats nice oc though

 

[Corporate Thug]

thats a hell of an OC there

 

[MiranoPoncho]

Damn, if only all the chips could oc like that. Who here says up the voltage on that radeon?

 

[morgash]

haha up the voltage. i guess there's no harm, dont care if it dies. someone wanna link me a guide? it actually just hit 550mhz stable but at 575 it locked up, so guess thats the wall. with some more voltage it could possibly see much higher clocks being that the temps arnt above 70F load lol. someone post a link to voltmodding a 7200 and i will hop on it tomorrow.

 

[StrangerGuy]

[(550-165)/165] * 100% = An amazing 233% overclock at stock volts! WOW!:Q

I wish I can do that on my P4...

 

[fliguy84]

that would blow gf3 out of the water!

 

[morgash]

bumpage

 

[Inappropriate4AT]

lol 7fps in 3d view, hefty overclock but still slow as hell.

 

[dug777]

Nice

umm did you superglue the hsf to the chip ?
i mean i thought you would have had to apply some thermal compound.
also why not put put another hsf on the memory as well. (sorry if that stupid cuz im a noob to OCing.

thermal coumpound isnt actually all that thermally conductive. It is just moreso than air. As for superglue, ti probably does 90% of what the thermal coumpound wouldve done, except that the 7200 dosent care since it makes all of 1 btu or something. The early ati chips were very cool running.

 

[morgash]

exactly right on the superglue, PLUS i have no other way to mount it effectively as thermal compunds need pressure to be effective whereas superglue can transfer heat simply through its adhesive bond. as for the RAM, since RAM, unlike cores, is specced for a certain speed it is quite hard to get it to go muh higher than that without some serious cooling. i stuck some RAMsinks on but that only allowed me to push it to 175mhz oh well hehe.

last night i took the stock HSF off my geforce 5700 ultra and am gonna see how far i can push a newer chip via the same method. will update l8r tonight.

 

[elkinm]

Now that is some over clock. My 7200s run hotter then that. I can get burned without he heatsink/fan.

I used to get 3500-4000 in 3dmark01 and under 1k in 3dmark03. I wonder what you will get.

What heatsink are you using. I think if it cools your 7200 that well, you should try it on a 9800 or x800, basically a recent card and make it into a X1900XTX killer.

 

[letdown427]

BUMP FTW

 

[morgash]

bump

 

[CrispyFried]

lol I have that card also, gonna have to try it.

 

[Fox5]

The radeon 7200 can display the fuzzy cube of ati tool? I thought that required dx8...

BTW, I'm guessing the 7200 was a passively cooled card? That would explain the massive overclock, and mean that newer cards wouldn't get anywhere near the benefit. Quite amazing how much beefier cpu coolers are than video coolers though.

 

[Powermoloch]

I wish...all GPUS are like that. Dayum !!!!!

 

[Killrose]

I've used a mixture of super glue and AS3 before, seemed to work good and the AS3 in there makes the heatsink removable because it weakens the super glues holding power.

I think i spread the AS3 on the mem chips and the superglue on the mem HS and then matted the two, and as I remember they adheard instantly allowing no time to position them. You can also just use super glue on two outside corners of the mem chips too.

 

[beggerking]

totally awesome OC! what do u get in 3dmark?

 

[Elfear]

Very nice OP. I love budget overclocking. I wonder what the WR is for that particular gpu?

You would have to overclock a 9800/x800 beyond the mortal realms of possibility to be an X1900XTX killer.

LOL! I really need to find a fix to the crash problem, cus I have an old 9250 around here, with a huge beefy pentium 2 HS on it and a 92mm fan, no idea how much CFM, but it crashes my comp <='( but maybe I get to overclock it pretty good to if it's got to do with the passive cooling

 

[morgash]

bump it up
