Get GPU-Z 0.38 and look at VDDCI, that's, or atleast I that is, VmemIs there a tool where i can see the memory voltage?
With GPU-Z i can only see the GPU Voltage. And if not i will just get my multimeter![]()
BTW a friend of my tried a XFX 5770 but no voltage control there yet. But thats the same as in the first post.

And BAGZZlash, will try that theory out then tonight, hope it works![]()

I need more beta testers. I implemented extended voltage control options I need tested. There are several groups of testers I need:
- 4770 users
I implemented L6788A voltage controller chip support (thanks to LKJask). Many 4770s utilize this chip. So if you have a 4770 you wish to volt mod, give it a try.
Download the beta version here.
Right, changed 0x18 on the GPU towards 1.274 Vcore, and changed the memory towards 1.2V instead of 1.15V. Furthermore clocks are changed to 1025/1300 on the 3D clocks, these are 24/7 safe clocks, tested them alot, so certain those are stable as a rock
Don't know if steps of +0.025V are possible on the memory, but I do know Vcore increases in steeps of ~0.0125V, so took 1.2V as Registers shows that steps of 0.05V are possible![]()
Yes I do have a 5870, yet a bit stuck on how to flash again, made a little CD a while ago to flash the new rom into the card, yet now I've lost that CD so need to make a new one, yet don't know how I did itDo you have a 5870 ?
I did testing on my 5850:
0x15 = 1.2
0x16 = 1.15
0x17 = 1.1
0x18 = 1.0
I did not see any changes when monitoring voltages with the multimeter Also my OC did not improve. So i think mem voltage control is a no go for 5850 cards.
I also tested fan control i changed tmax from 100 to 85. But it did not work. Fan speed was the same as before.

Solved, trying a flash now, made a backup of the original BIOS juist in case this backfires, and an extra VGA card is nearby, but hopefully it's going to work right away![]()
you mean to change the voltages under clock infos? You know, that there is no other voltage, but only a "---" available?

There is no VDDCI in my 5850 with asus bios...

...
Exactly. Just delete the dashes and enter a voltage near the ones in the registers (like 1.07 or something like that).
Indeed, 5850 BIOSes have only one VT1165 programming sequence. Is there anyone around who can confirm that 5850s carry only one VT1165?

Did two tests in the meantime:
[url]http://www.abload.de/thumb/t1919r.jpg[/url][url]http://www.abload.de/thumb/t2n3wc.jpg[/url]
both result in a standard 400/900 @1V without any regulation by the driver, but without bsods too
if the second VT1165 would be necessary to regulate the vram-voltage I would understand why my 5850 @5870-bios does not react on a higher memory voltage at all. 1,20 V instead of 1,15 V results in no higher clocks.
Edit: w1zzard´s reviews of 5870 + 5850 tell of 1 VT1165 (5850) and 2 VT1165 (5870)

I'm pretty sure that's the case. Thank you!![]()
BAGZZlash is there any progress to make fan control work for 58xx bios?

Quick question: for adding more volts to memory, do I have to modify the same "0x18" square under Memory registers or is it another one to be modified?
Thanks!
