I have never tried and would never try it :eek:
Because mine are like 82°C with your clocks&voltage and stock cooler@60% and room temp@23°C.
back to topic:)
Idle, I guess? Hurry up to get your Accelero S1 ...
Are u kidding me?:) That is heavy-crysis-load (1680x1050 High).. Idle is max 55°C.
That´s a lot lower as aspected on my site, but 60 % @ 8800GT standard is a lot of noise ...
back to topic?!
I really really really would like to have the 1,2 V-Bios :D
It is a bit loud, but u can get used to it.. On your Accelero max 60°C on idle?!
Of course on highest load, monitoring by ATI-Tool 0.26 (Everest shows approx. 8°C lower temperatures).
One is core temp, and the other is ambient temp.. I will get it till the end of the week. I hope:)
so, any programmer here to change the BIOS correctly? Or is it impossible.. Just our dialogs here..:)
edit: tippo
Yes, let us come back to topic - where are the experts to give it a try?
As far as I know the BIOS cannot be modified to give more than 1.1v. I tried to change the BIOS to 1.15v, and it defaulted to 1.05v.
None of the methods explained thus far in this thread will allow more voltage through the BIOS. The highest VID is 03, and the card doesn't recognize anything higher. If there is a way to get more voltage through the BIOS it hasn't been discovered yet.
The stock cooler is adequate for the 1.1v BIOS mod. Just turn the fan up a little. I can barely hear it at 67% compared to the rest of my system, but I usually turn it up a bit more (75-85%) if I'm playing Crysis.
I'm going to get the HR03GT when it's released, and then I'll be trying the voltage mod using a variable resistor. I'm looking forward to those 850/2000/950 clocks!
Hehe, for 850 core freq. you will need some COLD water;) And a lot of luck.. I think I will wait for GTS and then make a compare, and keep the price/performer. I hope GTS will run at 750+ without any mods. Dualslot cooler, no need to replace it.
Now that was really off the topic..
Im using the gigabyte p35-ds3r, what setting do I set in bios to make it boot from USB?
hi, I have a XFX 8800gt XT, default clocks are 640, 1650, 950, and I do the volt mod flashing the bios, nvitor say that is ok the flash, 1,1v on the extra voltage, and my clocks range now go up to 770 and still working, maybe can do more, I continue testing, shadders go up to 1750 from 1700, but mems clocks itīs the problem..., without vmod, maximun stable to all games, was only 960, and after vmod, still the same frecuency, 960, if i go to 965, after play 20 mins or 30 on crisys, or after play 5 mins on pro evolution soccer (other games donīt give me a crash), I have a green colored pixeler screen for 10 seconds, and then the pc is freeze, or give me a blue screen with a nv4_dsp.dll error, is vga mems the problem? or was my pc specs?, I have a opteron 165 @ 2750, and a nforce4 based motherboard (msi k8n-sli) 2x 1 gb ram ocz platinum ddr 400 @ 450.
I have the stock Cooler, with 100% fan, and have 88š maximun on crysis only
Thanks!
@mrkarate - It's the vRAM. It sucks on the GT. Turn down the RAM speed. 88* w/ 100% fan!? That seems VERY high. What are your ambients? I max out at ~72* w/ the 1.1v BIOS mod.
@Gas - I think 850 is doable on high-end air. I've seen others do it w/ less than 1.3v. 900 is even possible, but I've read performance actually drops over 850. These chips don't get that hot w/ a good cooler on them. I'll let you know how it turns out after I do the mod. I'll probably have to wait till Christmas, though, to get all the goodies I need.
There is a key to press during the post to pop up a menu that let you choose from where to boot. It one of the F keys (might be F12, not sure though), you can see which one is it during the post, it is written at the bottom of the screen.Quote:

so, there is nothing I can do?, most people have an xfx 8800 gt xt can put mems to 1000... :(Quote:

Select usb-floppy. BUt make sure your usb is floppy formated.
@new-b: your core is actually stable? Try ATiTool for like an hour, or go playing Crysis for an hour.. Beacuse my was stable for benches @771, but it locks up in crysis in five mins of playing..
@GaS
Yep...I only did about 30 min of ATiTool, but stable 2+ hours of Crysis.... I am on water cooling though so that may make the difference.
Max temps I've seen on the core is about 35c
Now that makes a difference:)
I have run some benches with Crysis and for 712 Core and 1728 shaders, the memory speed do have some importance. I gain 0.5FPS on avg at the Crysis GPU benchmark between 972MHz and 999MHz ... I know 0.5FPs is not that much but in Crysis the avg is in the 30s so every tenth of frame count :DQuote:

I`d leave the mem freq. near to 950-960 for 24/7 usage....the gain is pretty small i can see..
my current clock is 750/1750/960 stable crysis more 2 hours play, but, if I buy a coole (thermaltake hr-3 or something), can I do more OC?, or the current itīs the limit?
