GPU Tweak and HD 7850

Hi folks,
Well I finally did it; I bought an HD 7850, (MSI Radeon HD 7850, PE -power edition- to be exact). Here's the problem; I loaded Asus GPU Tweak and I tried two different versions the latest version, and then version 2.1.7.1 which I'm operating now.

In both cases I cannot get GPU Tweak to give me control of the voltage! I clicked on the "Advanced" mode and I've done everything I could think of to try and make this give me control of the voltage but I can't even get the slider adjustment to show up!?

On the latest edition of GPU tweak they had an additional icon at the bottom called "Power Track" which had a slider but didn't give any indication as to what it was increasing or decreasing when I slid it.

In addition, GPU Tweaks skin flashes on and off randomly as I passed my mouse over it on occasion. For instance in the present version I have, (2.1.7.1), the monitor panel has all of its "minimize/maximize" icons missing and I can see right through them to my desktop as if they were cut out of the skin with a razor blade if you know what I mean. It's also the same way for the "X" at the top right corner of that window.

They're not the only things missing but they're the only ones that I know are supposed to be in those empty boxes. There are other "empty boxes" of various sizes but I don't know what's supposed to be in those.

I can't find anyone who's complaining about this problem and I mean both problems; the problem of the missing GPU voltage adjustment and the problem of the flashing monitor skins.

If anybody has any idea of what's going on can you please give me some suggestions. Right now, without the use of the voltage regulating slider, I can only get the card to 1050 on the core clock and 5800 on the memory clock.

There are many people out there that easily get over 1200 on that core clock and that's what I'm looking to do.
Thank you, Rich

BTW: my HD 7850 default core clock is 950 MHz and the memory clock is 4800 MHz. This isn't the "Twin Frozer" model.
I do have the latest version of AMD's Catalytic Control Center installed.

WOW! Thanks Tooli20!! I all but gave up and settled for the 1050/5800. I got talked into trying the MSI Afterburner a second time because one of the people there felt I needed a different set of drivers.

So I installed that set and got the voltage control I was after but I lost 'OPEN CL"!! Then if that wasn't bad enough, I find out that even though the MSI tool will display that it's boosted the voltage to 1.335, it in fact castrates itself at 1.75v!!

Hell, GPU Tweak at least let me get to 1.21. Anyway, needless to say, I reinstalled GPU Tweak and my other drivers and settled for the 1050. I will DEFINITELY try that suggestion of yours as soon as I can stick my head up for some air, (I'm just plowed over with deadlines).

BTW, Are you saying that you can'ty use your own suggestion? Why can't you get there?
Thanks again, Rich

I've got to update my sig to that HD 7850. That card is an animal!!

"I don't know if 1.75v was a typo but I would LOVE to have my card "castrated" to that voltage...in fact, I'm actively pursuing it "

No, unfortunately that was a mistake, a typo. I meant 1.175. I will absolutely look into TRIXX and let you know but exactly when is uncertain. I have deadlines for my deadlines!
Thanks again!

Hey Toolio20!,

It's been about 3 weeks and 5 days since you answered my post regarding a better way to OC the 7850, and I was on a tight, tight deadline and couldn't try it out right away.

Believe it or not, I just got a few hours to 'screw around' and wanted to try out Trixx, (not yet downloaded or installed), but I have two questions:

I'm sure I have to uninstall GPU Tweak, no problem there).

But Is it absolutely necessary to completely uninstall the ATI Drivers if I had installed the latest drivers from ATI on or around 4 weeks ago? Just seems like an unneeded step when I consider that.

The other question is the Memory. In the post you said just "leave the memory alone for now". My 7850's memory is stock at 4800mhz... Shouldn't I increase that also? I mean, doesn't that help the whole performance to some extent?
Thank You,
Rich

Toolio, if this looks familiar, I sent it to you via PM yesterday but wasn't sure you got it.

Hi Toolio,
I uninstalled GPU Tweak and the old CCC and drivers per those instructions. Then I installed the latest CCC and drivers and then TRIXX.

The Trixx voltage still won’t go any higher than 1.21v which is how high I could go with GPU Tweak. Then there’s the slider that says “Board Power Li”, what is that? I left it at the zero setting it was at and increased my Core to 1150 and Memory to 1450, (x4= 5800).

GPU-Z confirms all that and the voltage to but I haven’t put the card under a load yet, (that’s next).

I still have plenty of room to slide the Core and Memory options well over 1500mhz each! But of course, without voltage, I’m wasting my time.

Can you tell me what “Board Power Li” does? There’s nothing on it in the TRIXX site. I’ll try to Google it and see what happens. I’ll put some load on the card and let you know what happens.

Also, I’m going to send this post to your PM as well just in case you don’t catch the post.
Thanks, Rich

If anyone else knows anything about that slider in TRIXX, can you please offer some assistance? thanks

Thank you! I understood you perfectly! Yes, I went and increased the PBL to the maximum 20% and I'll try again to get higher than 1050/1450. When I tried that 1150/1450 setting I mentioned in my first post, I got a very quick BSOD.

So I just put it back to 1050/1450 because I'm pretty sure that I wont get much higher without more voltage. Oh, I might get to 1080 or something like that but the trade off of heat and stability for such a small increase isn't worth it.

I had he GPU Tweak but the voltage only went to 1.21v. Then someone told me about TRIXX and after installing, I found that it only goes to 1.21v also! He said it would go to 1.225v which is what I need if I want to get to 1250 or 1300 Core.

But so far, GPU Tweak and TRIXX are the only two I tried that goes to 1.21v. I've tried every other OC program from MSI to:rolleyes: .... well, I forgot the names of the others, but I tried a lot of them.

Thanks again for your help,
Rich
PS, I need to update my specs in my signature. I have a MSI Radeon HD 7850PE, (power edition).
