8500 O/Cing

No_Style · Jan 7, 2003, 03:25 AM

It's been awhile since I've inquired about this. (Hell, I should have inquired about this when everybody still had 8500s) But I'll ask anyways. I have a SapphireTech Radeon 8500 LE. It came at speeds of 250/200. But now it's at 297/232. Others have flashed OTHER types of BIOSes in and such ie: Retail ones into theirs and such. But I can't. I get corrupted display. Why is that? Another thing, most people seem to be able to overclock their memory to great lengths, while for me I can only overclock my memory so very little. I can't even reach 250! BTW I overclock through the BIOS. I could reach 250 with a program..but if a program could do it, why can't a direct BIOS change in clock speed?!

Thanks

What are your cards default speeds?

No_Style · Jan 7, 2003, 07:43 PM

250/200...

ive never actually used an 8500, but i do know that cheaper brands of board (ie. sapphire) use lower spec ram than the more expensive brands do, so the ram on your card is probably only just capable of managing stock speeds...

and example of this is my old inno3d geforce3 ti200, other people were able to reach much memory speeds of 650Mhz + on branded boards, but mine was only capable of 444MHz max (400 stock)....

It's quite discouraging indeed

just keep it in mind next time u buy a card, get one from a well known manufacturer and i guarantee you will be impressed, it is worth the extra cash in the long run...

The_Neon_Cowboy · Jan 8, 2003, 08:07 PM

are you useing ram sinks? (heatsinks for your ram) And really good case cooling? the memory might be a slower refresh look into the speeds. alot of nvidia cards are like 3.2 ns where as a cheap card might be 6 ns it makes a big difference when you overclock... Not to mention ati cards are buil desighned to have the memory run at the same as the core clock for best performance where nvidia thrives from haveing the memory clock speed much greater than the cpu... hell my msi gf4 4200 will go to close to 600 mhz on the ram it even comes with a program to test and overcock the memory for ya! good luck!

not mot mention alot of LE's are cutback economy versions (cheap ass slow memory)

No_Style · Jan 8, 2003, 09:14 PM

Yes the Memory timing is slow..and I do have RAMsinks, but that doesn't answer the question of why program clocks higher than flash. Hmm..?

You should use the pencil trick, this is an easy way to do an efficient voltmod!

My first couple of cards were cheapy OEM, me last few have been major names that are good. (Asus, ATI, & Visiontek) There is a WORLD of difference, especially when it comes to OCing 'em!

You ain't doing yourself any favors trying to save a few bucks to get an OEM or budget card....honest.

why my r9000 (non pro) cant reach memory speed at 250 when it has a 4ns hynix chip? 4ns should be able to handle 250 i presume. (1/4ns = 250MHz). the highest speed i could manage is 220 with ramsinks on every chip.

Falstaff · Jan 16, 2003, 06:16 AM

yep, the pencil trick is really worth it...caution man, you really can screw up the card,

I possible reason for this is that the bios changes the memory timings to be more aggresive. While of course the program only alters the raw speed.
