Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/16 17:24I already gave you my BIOS previously, it's the Sapphire Radeon X1650 AGP 512MB one with factory overclock of 594/797MHz but RaBiT says its 600/800MHz. And it also says its 256MB. Is this the one that you can modify? Here it is again though. Sapphire Radeon X1650 512MB AGP Edition - Memory : 512MB - Bus Type : AGP

Okay, well you need to forgive me but I can follow each one of you guys of having supplied the original BIOS or not. So I will check it later on as I am not at home right now, but just had some free time to logon to the forums and check the activity. I will check it later though and get back to you.

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/17 20:17Well, I think you are right that with the current available RaBiT version it is not possible but you are lucky that I have a better beta version that I can't share, but I tweaked your BIOS with the requested clock speeds as you wanted... So this is your Sapphire Radeon X1650 PRO with 512MB memory on the AGP interface but clocked now at 655/931MHz.

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/17 22:50The card defaults to 594/797MHz (1594 effective), and RaBiT said it was 600/400MHz (so 800MHz effective). And I tried using the BIOS you gave me, but I get an error when I try to flash it. But I edited the temps. What can I do to make it flash the card like it should?

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/17 23:00When you flash in Ms-DOS from a bootable media as you should using ATIFlash can you make sure that the name of the BIOS is always within the "8.3" characters limitations? Meaning maximum 8 characters for the name and maximum 3 characters for the extension? And make sure you just flash the BIOS without your tweak to make sure it works as is? And do you tweaks once confirmed my update is working. Now just to be save your DDR2 memory runs at 1594MHz effective? Cause I doubt that very much...

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/18 03:21Well GPU-Z says that it is 797MHz and I am in the understanding that GPU-Z always reports the single rate, and Everest says real clock 796MHz DDR, original 400MHz. Effective clock 1592MHz. And bandwidth in Everest is 24.9GB/s and GPU-Z says 14.9GB/s with DDR2 at 466MHz.

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/18 07:12To be sure please look for the memory chips on your card. What is imprinted there? I think it is impossible to run DDR2 with real 800MHz. On the modified BIOS check the checksum. Your original has 2100hex/8192dez. The checksum of the modified BIOS is 2000hex/8448dez. Change at offset 0x00000026 and 0x00000027 from 00|00 to 92|6E to reach the checksum of your original BIOS.

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/18 18:59Indeed check the memory chips on what is imprinted, cause I am certain that if you can run those memory chips higher than 1000MHz effective that it is not DDR2 at all, cause such fast DDR2 was never made. So it could well be that you got GDDR3 memory that is heavily underclocked to 800MHz from origin and that is why you can reach almost 1600MHz effective when overclocking. But with DDR2 that is just not possible...

Re:Sapphire Radeon X1650 (RV530), some BIOS help wanted? - 2007/12/19 02:30How do I tell what it is, like DDR2, GDDR3 or even GDDR4? Tere are four Qimonda chips on the side with GPU which I am assuming is the RAM, though I could be wrong.

Well we can tell you when you provide us all that is written on those Qimonda chips as then we can check the technical specifications and those will reveal what type of memory it is and what it is capable to do... So please write down for us all that is printed on one of those Qimonda memory chips.
