Edit bios voltages

[wtf8269]

Is there a bios editing program that will let you set the voltages for ATI bioses? I've seen one for nvidea that allows you to change voltages.

Here is the link to that nvidea editor I was talking about.

No I am sure that the only way to get higher voltages is to mod. Thats what I have heard anyways.

Yeah but doing a volt mod that way, even just the pencil mod makes me nervous. I emailed ViperJohn and he said my cooling isn't good enough for voltage modifications. I don't think he understood that I only wanted to go up to about 1.45, not something crazy like 1.7.

cant change voltage via software/bios on ati cards .. only a voltmod will work

Yeah I know what you mean. I want to do it, but I don't want ot risk my card. You should be able to do a small vmod on your cause you have a good cooler. Its says in the article on this site that with air you can go to 1.45V.

-Dan

 

[wtf8269]

Yeah, ViperJohn had me have the Nature test in 3dMark 2001se 15 times then record my temps, and ATI Tool read a max of 46. He says that my temperature probe is just reading really low because the probes are usually +/-8º off. I still think it's pretty accurate seeing as I had 150cfm blowing directly on the card, and 225cfm exhaust. In addition the room temperature had to be 65ºF or lower. So I replied to him saying that even if I had the worst case scenerio and both my idle and load temps (34/54) would still be pretty low, and I asked if that was too high for even just a volt mod to 1.45, because I didn't want to do any more than that on the core. As for my ram I just want to be able to get up to 560-570mhz, and it can reach about 545-550mhz as is.

 

[djbbenn]

Do you have AS5 one your cooler? I don't think that is to high even if your card probe is off +/-8C. Some people you see hit like 70C at stock because of their cooling and air flow is not good.

-Dan

 

[wtf8269]

Of course I have AS5. The ramsinks are just held on with double face tape though.

 

[wtf8269]

Well my friend is coming over here and he knows how to work a multi meter unlike myself so sounds like I'll be getting a pencil mod going here.

 

[djbbenn]

Sweet, tell me how it goes.

-Dan

 

[wtf8269]

Vcore went well, its at 1.46 and the core can get up to 567mhz now, thats at 49ºC. I think I might be able to do 1.5v but I don't know. Haven't done any benchmarks yet.

I'm having some problems with the VDD though, I reduced the resistance on the R311 chip from 1008 to about 965, and the voltage only went up from 2.08 to 2.09 and my memory wont go any higher than it used to, whats the deal?

I reduced the VDDQ from 765 to 740, and the voltage now reads 2.16 on that, so that worked out fine.

 

[djbbenn]

So thats like 27MHz higher than you had before right? Sweet! For the VDD though...kind of weird that you lowered it that much but the voltage only went up that little. Maybe it was measured wrong, like the amout of resistance on it. Tell me how it effects your benches too.

-Dan

 

[wtf8269]

Well I did an Aquamark3 and my score went up 1k. I'm quite willing to go to 1.5v though, and then I might be able to reach 600mhz core. As far as the VDD goes, I followed the directions exactly, did the mod on R311.

 

[wtf8269]

Holy shit, I'm retarded! I did raise the VDD. I forgot that stock was 2.01v. (I even had that written down!) So I actually raised it .08v, it just didn't make much of a difference. I think I'm going to try 2.16v VDD and 1.5v VGPU tomarrow seeing as though I have ramsinks and my temps are still well below 65ºC which I wouldn't like to see it go any higher than.

 

[djbbenn]

600Mhz core would be sweet, what are you getting on the mem?

-Dan

 

[wtf8269]

Well today I got it up to 1.57vgpu and 2.2vddq and it didn't go past 55 load, but it seemed to be having fluctuation problems so put it back to stock for now and I'm going to wait until I get an OCZ PowerStream. Although, I was able to get it up to about 585/550 stable. I don't think I'm going to mess with the memory much just because core is what makes the difference and I don't want to push my ram much seeing as though the volt mods on that didn't seem to take too much affect.

 

[djbbenn]

Ya a better PSU will help, I have been wanting to get one of the OCZ Powerstream's. You should be able to get close to 600 with the mem. I got 570 easily without vmods on mine. But core does give the most.


-Dan

 

[wtf8269]

Sounds like you have either a better overclocking card than mine or a better psu because my max core is around 550 with volt mods before it black screens and shuts off the card.

 

[djbbenn]

I went up to 550 core and 570 mem and my screen went out...thats with no vmods. 545 is about my max core so I have it at 540 to keep it stable. The highest I went on mem was 570 and think I can higher. But that might because I don't have the remaining 4p unlocked. Thats on stock cooling too, can't wait untill I get a Zalamn or some water.

-Dan

 

[wtf8269]

Zalman's are great especially if you get some extra airflow on them from the side panel.

I think I'm gonna go with the 520w PowerStream because it has a little bit more amperage, plus since its 520 constant 620 max it will last me for awhile seeing as most systems don't quite need that yet. I've actually got two of these 410w Thermaltakes, the older one I'm selling for about $45 because I didn't use it for long, and my current one I think I'll sell for around $30 or $35. That'll get me roughly $80 and since I've been working my @$$ off around the house now I earn about $40 a week.

 

[djbbenn]

Yeah I know. I have a Vantec Spectrum and a side fan right next to my video card. Look at my pics there. That would really help with a Zalman.

Nice, I was looking at your wiring and it seems pretty neat. Last night when I was looking around on Overdrive PC I was looking at some of the insides of their cases and I think most of us know by now how well professional custom computer companies do their wiring. Well I noticed one little trick where in a Lian Li PC-60B (same thing as mine except no window), what they did is they actually cut a hole on top of the motherboard tray for the PSU wires to go behind the motherboard. It was quite clever, I'm half tempted to do it, but I don't feel like clearing out my case. (Don't want any metal shavings on our components now do we?)

You can see it here if you look towards the top of the motherboard.

 

[djbbenn]

Thanks Aaron. Thats a good idea though that they have with the tray and wires. I' with you for not wanting to take your mobo out to do it though. I find just by covering the wires with a sleaving will make a difference. I was looking into one of the OCZ models of the PSU's. I like how the Modstreams cables are already sleaved and they are UV too.

[Urlyin]

Yeah I know. I have a Vantec Spectrum and a side fan right next to my video card. Look at my pics there. That would really help with a Zalman.

-Dan

Looks good Dan ...

For a power supply may I suggest you look for something with two 12v rails ....

 

[djbbenn]

Thanks Urlyin For the psu got any in mind?
