Re:Radeon BIOS Tuner (RaBiT) v2.2.1 software do give feedback? - 2007/02/05 10:13Hi all this is my first post here! I have a Sapphire Radeon X1950 PRO 512MB AGP and RaBiT v2.2.1 did see correct my card but still with 256MB and not 512MB. And...is it possible to add voltage ajustmemt for memory? I can't overclock memory not even 1MHz (1404MHz default) without getting wierd colors even on desktop screen. So far tried overclocking the memory with CCC, ATI Tray Tools, ATITool and RaBiT.
With the CCC OverDrive it doesn't do anything but with others I can manage to overclock the core at least to 630MHz but memory overclocking is giving me bad colors as I said. Is it a voltage issue or something else? Thanks in advance!

Re:Radeon BIOS Tuner (RaBiT) v2.2.1 software do give feedback? - 2007/02/07 15:29All sorted had to do it in the 2D bit on the overclocking and its now sorted... Got now GPU at 620MHz and the memory at 730MHz (1460MHz effective). Now it reads right...

If those are set too strict then even with giving more voltage to the memory it will solve nothing at all. Can you check which memory chips your card is using? Then we can look at the specifications and start to investigate it further.

Re:Radeon BIOS Tuner (RaBiT) v2.2.1 software do give feedback? - 2007/02/08 14:50Hi all, I have just signed in to let my RaBiT feedback here. I have a Sapphire Radeon X1950 PRO 256MB PCI Express and I have the same problem. I'm not able to overclock this card. RaBiT doesn't work, infact when I flash the modded BIOS I get 574/1390MHz frequencies. ATITool, RivaTuner, all 3rd party utilities doesn't works on RAM. ATI's OverDrive causes screen flickering and artifacts, even with 1MHz overclock on the GPU or on the memory, this doesn't make a difference. Hope you can find a solution.

Re:Radeon BIOS Tuner (RaBiT) v2.2.1 software do give feedback? - 2007/02/08 16:16Well, I was in the same as you but all you do is clock it in 2D mode on RaBiT and OverDrive in RaBiT and it works fine. All sorted had to do it in the 2D bit on the overclocking and its now sorted... Got now GPU at 620MHz and the memory at 1460MHz. Now it reads right...

Re:Radeon BIOS Tuner (RaBiT) v2.2.1 software do give feedback? - 2007/02/08 17:25Oh yes, you are right, it works now. Sorry, didn't see your previous replies before. I have a question, voltage changes works in override 2D mode too? I got 600/1460MHz on my card, I think I'm PSU limited (Enermax 400W Liberty). Thanks a lot.

From my little research I found out that these are the fastest GDDR3 chips that Samsung offers and rated at 1.1ns (1800MHz effective at 2.0V) but you already know that. Samsung GDDR3 Memory K4J52324QC-BJ11
I found some details on these from a Radeon X1900 XTX review... The fastest GDDR3 memory chips (K4J5324QC-BJ11), which works at 2.0V voltage and at 1800MHz frequency, consumes a current of 1180mA and has a power consumption of 2.36W... Although Samsung's specifications says 1.8V. I believe that there's something with timings as you said or/and with voltage. Can't think that these chips are set to run at 1400MHz with 2.0V.
Stranger is that they don't take even 1MHz. Is it possible to have a lock or something? Just one more question. What's those two switches placed on the reversed side of the PCB, between the core and the memory chip? Does all this need separate topic? If so, please... I'm looking forward for your reply from you experts!

Re:Radeon BIOS Tuner (RaBiT) v2.2.1 software do give feedback? - 2007/02/08 22:13On the Radeon X1900 and X1950 series cards its not a card fault more then a driver issue. I couldn't do squat with the Catalyst 7.1's until I did a complete uninstall and manually deleted ATI files and registeries. Then reinstalled them and now I can overclock like mad with no real issues...

From my little research I found out that these are the fastest GDDR3 chips that Samsung offers and rated at 1.1ns (1800MHz effective at 2.0V) but you already know that. Let me enlight you on something, those are not the fastest GDDR3 memory chips from Samsung! Samsung has since this year also 1.0ns memory out... And yeah I know all the memory stuff and specifications so I just needed to know the exact number, which you gave. And that is not the newest ones, Samsung has produced better already.
Now for these memory chips to operate at 1.1ns and then being able to do 1800MHz or more, cause yes these chips are fast and can do even more then what they are rated for like 1900MHz should be possible. The specifications also clearly state that the "-BJ" requires 2.0V to operate at their rated speed, so that means for both the "-BJ11" and "-BJ12". The other chips in the same range come with the "-BC" and only require 1.8V but the fastest on those is only 1.4ns.
Now I will have to check your BIOS and check the timings against the specifications, so I will do that... But yeah your posts should better have a topic of their own as it is not really a RaBiT problem nor feedback at all...
