EDIT: just a warning, this is the first 450 BIOS iv'e modded, so whoever try's it first is the guinea pig, if it bricks your card, you did it at your own risk..
On stock bios, i can reach 1060mhz on my GTS450, i fear the OC with an unlocked one ;)Quote:

@Gaul: Please report back let me know if it worked.
If it works I'll start a 450 bios mod thread, if not then I wont bother.
i'm search compability list first, did NVFlash-5.95.0.1 support gts 450 ? wait wait......Quote:

450 bios thread here
http://www.xtremesystems.org/forums/...d.php?t=260220
Here is vBIOS from Sparkle GTX 460 1GB, card is that newer revision with purple fan.
Is it possible to make a few changes to this BIOS?
- Default fanspeed 30%
- Max fanspeed to 100%
- Max voltage limit 1.2v
No need for other modifications.
you got itQuote:

One question about flashing with nvflash: It apparently supports only .rom files so is it ok to just rename bios file from bios.bin to bios.rom?
Yes, just rename to bios.romQuote:

Did i miss it? Can anyone explain it. Tanx
Upload your BIOS and I'll mod and add it to the list. Just a oversight.
You mean when you checked the P0, it was already at that range of values ?Quote:

Does anyone have a newest TOP 1GB bios?
My card OC's at 900MHz with 1.100v, but the memory sucks .... @2100MHz it crashes.
Is any way to increase the vMEM on the GTX460?
Thanks.

Have you tried lowering your GPU clock to say 875 and seeing if the memory will go higher?
I do not swear but I think I tested the mem with the GPU @ default .... must try it tonight again.
I think this memory sucks bad ... anyone can pull 2100 / 2200 on other boards :(
But you are saying that because it could be the GPU ? Do you thing increasing the GPU voltage beyond 1.1v will help the mem?
The mem voltage is hardware controled ?
Increasing GPU voltage won't help the memory, but the memory controller is built into the GPU. Relaxing the GPU OC a bit could well give you a memory frequency bump. I run my GTX460 @ 855/2.25GHz 1.075v for 24/7 use and its scores are easily comparable to a GTX470. I wish sometimes I bought a faster stock clocked GPU so hopefully I would of got a card with less leakage, but 855/2.25 isn't exactly slow.
If you increase your GPU speed and voltage, your memory will become unstable at 2.25?
No. For me theres just no practical gains that outweigh the heat output. Both GTX460s I have tested (KFA and Asus) both OCd exactly the same on the same voltage. So its fairly safe to assume some kind of binning process is going on with higher stock clocked GPUs being able to OC further. Anyway I'd start by resetting your cards OC, setting voltage to 1.075, and seeing how far your memory will clock with the GPU letf stock. If you can get it up to about 4200/4300 youre doing alright. From there see how far your GPU will OC before crapping out. My moneys on about 840-860MHz.
Ill try that late tonight ;)
But 840-860/4200-4300 will have a better performance vs 900/4000 ? What do you think?
Depends on what 3d app/game your running, but generally NO. The 256bit (1gb) mem models are not held back by memory bandwidth, so you will gain more from your core clock OC.Quote:

At higher resolutions and games that use high res textures 850/4200 or thereabouts should do better than 900/4000 as high res textures require more memory, and obviously as you can't add memory to a graphics card the next best thing is to make the memory faster so those high res textures can get flushed faster when their not needed.
Wrong. Set your core clock to say 880MHz and your memory at 4GHz, now run the GPU tests in something like vantage at max resolution with AA/AF, then do the same thing again only with your memory at 4.25GHz. You will get a 200-300pts GPU score increase. At 880/4000 the card is starting to get bandwidth limited for higher resolutions.Quote:

Shading/Geometry/Filters/Tess/Physx/etc. need Core/Shader Clock
I find in general, that GPU core/shader clock brings the largest gains.
Have a look. At 900mhz core 4000 mem, with only 22% mem controller load, hmm, looks like I have a buttload left over.
Same thing at higher res with 4xFSAA
