Now you can use ATI Tool to oc to your heart's content. Just set the voltages like you have been, making sure to apply before going back to the main screen. You should be able to hit ~700-725MHz at 1.425-1.475 on the core and 800-875MHz at 2.1-2.2V on the mem. Set the VDDCI to 1.5V to get some more stability out of it. You'll probably want to increase fan speed to 50-80%.

Sorry if I explained more than you needed but I wasn't sure how familiar you are with the new ATI cards.

Thanks for that bit of indirect advice.

I'm having a bit of trouble with choppiness in Quake 4 on X1800XT Crossfire and I'm not sure if it is due to heat issues with the GPUs or the dual core processor. I've heard of choppiness on dual core and also wondered about thermal throttling. I ran Prime95, Folding@Home, the ATI Tool x-wing artifact scanner thingy, and a virus scan to warm things up before running throttle watch. This combination ran all night long with no throttling, so that is eliminated as a culprit at least. The CPU gets up to about 67°C after running like that overnight though, which is pushing the limits of how hot I like things to run. It only runs about 56°C when running Folding@Home or a game though.

what kind of dual core? an intel chip?

cuz if its AMD you got trouble... never let it go over 60C... try to keep it under 50C and 70C is the "I hate my cpu" temp for AMD dual cores anyway =P

the BS thatis propogated by the ATi fanboisim trying to depict things they've never seen, touched, yet only read about passively.

funny thing about you fanATIcs, you try to convince others so blindly to go ATI, yet when someone wants to do this assessment firsthand, you call it BS? lol

as i said, i have both cards here now, if you don't want to help me look at both of these cards accurately, please troll somewhere else

Food for thought... Maybe it's the comments in your sig that are making you a bit less than totally objective. Actually, even using the phrases like 'Time for the BS to stop' when attempting to expose or look at facts makes you look a bit immature IMO.

You also never answered my ealier question...

You have one now, why wouldn't you have one later..?

I hope you aren't in the process of dispelling BS by purchasing a video card, OC/flash/modding it, and then returning it when you're done... Not saying you are, just trying to get my facts straight. I'm curious as to how well your extremely OC'ed 7900GT will stack up against an X1900XT, but I also want to know who the results are coming from.

 

[5150Joker]

Hang on, let ST do his benchmarks and see his results first. We all know where his bias lies but he can't fabricate results either because they can be easily verified. I'm interested in seeing where this goes as well. Don't forget to post pics of the X1900 as well as your receipt...not that we dont trust you.

Golgatha take a look at this thread and see if it does anything for you: http://www.hardforum.com/showthread.php?t=983781&page=1&pp=20

 

[thilanliyan]

I'd also like to see some of the benches. As 5150 said they can most likely be verified.

 

[Elfear]

I'm sure there are plenty of people who'd verify the accuracy of the results. My system is very similiar to ST's so I'll post up some numbers if needs be.

Thanks for taking one for the team. I wish you had pushed your voltmodded 7900GT further before comparing the cards, but your numbers should be close enough.

what makes you think he can push his GT further?

he's already way over what most people can attain with theirs.

 

[Extelleron]

Regardless of the outcome of these benchmarks, the voltmodded scores CANNOT be compared to that of the X1900XT. First of all, the 7900GT is ALOT harder to V-mod than an X1900XT, which can have its voltage increased via software. The 7900GT requires a fairly simple volt-mod on the hardware itself, but those inexperienced could easily make a small, small mistake and kill their cards. Therefore, there is a huge risk in volt-modding the 7900GT.

These cards can go to 680~/1700~ at 1.5v with some better cooling. If you got more extreme cooling, they might as well hit 800mhz on core and 2000mhz on the vRam.

Most people stay at 580~/1550~ and thats at 1.2v just to be safe. Others are the ones who increase it to 1.5~1.7v and have there GTs at quite disturbing speeds.

And have it die in a few months. 1.5-1.7v is not safe for something that's supposed to run @ 1.2v. There's a reason why these GT cores werent chosen for the GTX: They shouldnt be running at those clockspeeds/voltages.

Using extreme cooling you can push an X1900 near 800 mhz too so what's your point? I run mine on water (with fans on low) using software voltage control at 1.57v and I can achieve >750 mhz on the core and 870 mhz for the memory (which only has ram sinks on it).

So with that logic, the price of a video card that includes a rebate shouldn't be compared to the price of a card w/o rebate because sending in the rebate involves a lot more effort and there's always the chance of someone making a small mistake and the rebate not being honored? Come on, its benchmarks for 2 video cards, don't take things so seriously.

I ment extreme cooling as in some obese air cooler thats normally implemented by the hardware enthusiasts.

And have it die in a few months. 1.5-1.7v is not safe for something that's supposed to run @ 1.2v. There's a reason why these GT cores werent chosen for the GTX: They shouldnt be running at those clockspeeds/voltages.

Then whats the point in OCing? Why are many people doing it then? You think people dont know this already? So then whats the point in having the software voltage tool for ATi? have it die in a few months like you mentioned? Same goes to alot of people in AT where they have OCed their AMD CPUs and raised voltage on it as well... and according to you it will die in couple of months time.

Quoting vr-zone:

These cards are one of the most overclockable cards on air if you do it right. It will be fun to put 2 of these MHz monsters in SLI. What I find attractive about these cards is how accessible these clock speeds are. You don't need watercooling for it, just good air-cooling. And the SevenTeam 480W power supply we used during testing is more than enough to keep the card stable.

 

[5150Joker]

Cookie, all they did was a test run at 1.5v. Long term stability with a 7900 GT at those voltages hasn't been proven yet. In a few months time we might start seeing an assload of failed 7900 GTs because of this mod. Even I don't run my card at 1.57v longterm, I only do it while gaming and then I set it back to stock volts. Unfortunately with a modded 7900 GT, you're stuck at 1.5v+ constantly, thus potentially reducing it's shelf life.

I know what you mean, but time will tell. (Alot of us has been running our CPUs with the voltage raised and OCed for a long time. Same applies to GPUs. They fit in the same aspect. Most cards can last a long time, e.g im stilling using a GF4 that was bought 4~ years ago! and its been OCed and volt modded slightly . To me these 7900GTs just like any other volt modded product will last quite a while, last just enough til the user can jump to DX10)

 

[Keysplayr]

I have seen 700/1800 on 1.4v core on a GT. What is the stock core voltage for a 7900GTX?

1.4v

Thanks. Then I don't see much of a problem running a GT at 1.4 to 1.5 with proper cooling (key factor) if the GTX is designed to run all it's life at 1.4v. Same core, same process, same everything. Anyone else see a prob?

 

[Cookie Monster]

They might use a different PCB hence the reason the accelro X1 doesnt fit on 7900Gt boards.

Ah, that's right. I have heard that the AC5 rev. 3 can be modded to fit the GT's. I'm not certain that it cools the memory though.

so?

you oc an 1800XT to 1ghz. should we use that as an example when comparing everything?

ST's card has a very good overclock. one that is matched (or exceeded) by VERY SMALL % of GT's. some of you ppl talk like 700+mhz is an easy overclock, and that's not even close to reality.

 

[Cookie Monster]

The X1800XT wasnt even stable enough to bench. The vr-zone folks i consider that they are good at OCing (mostly due to shamino), and the fact they stated that the GT was stable even at 700+ mhz on the core unlike the X1800XT using air cooling and a 480W power supply!.

Most GTs are atleast hitting 550/1600 on core/mem. Thats already close to 7800GTX 512mb speeds. (plus thats 1.2v stock volts)

Yes but are more than a handful hitting 700 mhz? Since you asserted to speeds as high as 800 mhz being easily attainable via air cooling, one would think 700 mhz would be a piece of cake. For example, here's some quick data on what X1900XT and XTX users are getting with their overclocks: http://www.ocforums.com/showthread.php?t=440151&page=1&pp=30 This is without any sort of permanent hardware mods (e.g. soldered volt mod); majority are stock cooling and the rest are on water and other types of cooling.

ugh..

apparently you cannot comprehend the point, so never mind...

 

[Stoneburner]

At least let him show some benches before criticizing them. Maybe he'll find ATI to be far superior and switch? Maybe he'll prove that the voltmodded 7900gt is a good value. Don't dismiss him just because he's clearly biased for NVIDIA.
