Overclocked E1705/9400 7900 GS Benchmark Results - Page 26

The reason you are scoring higher without the voltmod has nothing to do with synchronizing the clocks, it's because your card is hitting core slowdown threshold due to heat. If you experiment you can fine a voltage that will give you much higher clocks and no core slow down. I suggest 1.2V.

I tried go up to 575/1150 at 1.24v, but still get slight artifacts using ATI Tool. Have I reached the memory peak at 1100? Is it okay to have some artifacts? Could I go 575/1100 to compensate?

Reaver I took your advice and went to 1.2v. I prefer the voltage stability -- I guess it is piece of mind. So now I am at 550/1100 at 1.2v.

Anyway, would like to hear other suggestions you may have. Have a good one.

I would try loweing the memory and test for artifacts, if they popup again then you know it's the core and you can adjust it accordingly.

if you dont gametest your clocks its useless, try gaming for 2 hours on oblivion or fear.

8643 - Moretorque04 - T7200 / 2GB 533 / WUXGA / 80GB 7200 / 7900GS / 91.47 / 90W PS @ 550/1200/1.24V

I'm fairly impressed with that number. Id love to crack 9k though.

I ran it at 575/1100 at 1.24v and had no artifacts. My question now for Reaver is should I be more concerned about game performance than artifacts detected by ATI Tool as suggested by Yolda? Is slight artifacts with 575/1150 a problem or is it expected? Thanks.

ATI Tool will detect even the slightest artifacts, so if your games run fine then you shouldn't be concerned about ATI Tool, your GPU will probably even become accustomed to the speeds you've set it at as it 'wears in'. However if you get any BSOD or freazing in games I would clock it back, I would also suggest lowering the voltage a little, 1.2 should be fine and you can always try 1110-1140MHz Memory.

Thanks for the quick feedback and the help. I am going to lower the voltage to 1.2 and see how it goes at 575/1150. Anyway, have a good one and thanks for all the help Reaver. We need more people like you on every forum.

wow 6500 is really low for a 7900GS with that clock setting, you may be overdoing the core, if you go to high on it it will give you a lower score, try 600\1200, thats what i had mine at and i would get mid 8000's for a score, i even had it at 635\1250 it ran fine but was getting hot, but no two cards overclock the same some better than others, my friend's e1705's 7900gs can only max out at 575\1125 with the 1.24v gtx bios mod, and powersupply wise, mine ran cooler temps with the 90w over the 130w, which was strange but it worked. what are your max temps at those settings?

Hi,

Finally thx to yoda i overcloaked my 7900gs at a little 600/1200
no problems with a vid 7 at 1.05 V
but i have some questions :

1) first is it possible to push away my memory frequencie by increasing timing ?
2) i don' t really know what is the real difference between...vid and voltage...
why ? i think temperatures are too high for a little 1 volt overcloak, so what 's the difference between vid 3 and vid 7 ??

3)i have high temperatures under window (just reading some news) but i didn't overcloak 2D or throttle frequencies and voltage...high temperature : 70-78 degrees until the fan begin to run at 78...

What can we do to resolve this situation ? in fact i would get a more stability as i was at 440/1100 with stock rom with an overcloak at 550/1100 for exemple...
but the problem is i have high temperature without playing that's the matter...
then witch driver do you recommand ?
thx
sorry for my poor english level...

i run at 570/1150 with no artifacts, i get them when i set the core to 610 or above, anyway to increase the voltage up more, or will it hurt it?

What voltage are you at?

1.2v, ok but wich vid is it ? vid 6, vid 7...

Yolda i think we made errors..
putting vid7 to 1v does not change anything in fact the real voltage is the same : 1.24 v !!


i understand now my temperatures....

Ok time for a stupid question.

I'm having a heck of a time making a boot disk, which is driving me nuts because I don't think I'm totally useless when it comes to doing stuff on my computer.

Anyways there are very detailed and step by step instructions for this OC proceedure, right up until you get to the part about making a boot disk...then it goes something like "put the files on a boot disk and there you have it".

Well, 5 disks later and nothing has worked.

How specifically do you make the boot disk? What program do you use and what are the instructions step by step? I've heard some mention of a program called Nero?

The boot disks I've made just don't seem to do a thing. From the F12 screen I select boot from the CD/DVD and PB..2 pops up on the screen for about a millisecond, and then the computer just boots straight to windows as normal.

Any help would be appreciated.

Ranick are you trying to burn Jokers .iso file?

Download a trial version of Nero. Open the burning program then go recorder/burn image. Select the .iso image and the finalize disc option. Then burn.

is there a way to set different voltage? i though by putting the "v" in that it chaged the voltage to a set number. anyways how do i tell what voltage im running at let alone change it?

When I run the boot disk and load the 4001100.rom and then restart to windows, ATI Tool is telling me that the CORE is 400, but the Memory is 275. Is that correct or am I doing something wrong? Also, what would everyone say is the safest "good" configuration of my card and what should my desired temps be?

I think that is correct smoothdogg00.

275 * 4 = 1100. DDR2 memory quadruples the normal frequency.

Someone will most certainly correct me if I'm wrong.

Well, first off... when I O/C mine to anything with the volt mod, my temps get too hot (around 90 C) when playing games. I can however push it to 575/1200 and get no artifacts, so Im sure it would go higher, but I would not keep it that way permanently because of the heat. The highest I can go without vold modding it is 450/1200 before artifacts start showing up, but the temp stays 10 degrees cooler under stress (80 C).

Is anyone having any luck with different volt settings between 1 and 1.24? I think I could still get 550/1200 with a volt somewhere in between 1 and 1.24 while still maintaining reasonable temps below 85 C.

Hey thanks for the pointers guys, I thought being such a dork wouldn't get me very far. Anyways I've been succesfull in making the boot disk, and after some late night trial and error and much cussing and swearing I pretty much got the same results as jedipimpin.

I used ATItool to check for artifacts and was able to go to 460/1150 before I started seeing pixel errors. 450/1150 gets me a single pixel error about once every five to seven minutes so I'm thinking that is an anomoly and not because the card is pushed too far.

I'm let down by the performance of the OC and a bit mystifyed. My initial attempt was a conservative 420/1200 (coolbits showed my optimum at 418/599). I got a ton of pixel errors on the ATI run. I backed the memory down to 420/1150 and it ran just fine. I started bumping the core until I found the errors at 460 and backed it down by 10. Funny thing is, my card never went over 78C even at highest setting I let it run on (460/1150). At my current setting of 450/1150 it stays steady between 74-76C durring the ATI test. When I run 3DMark05 it never gets above 73C.

It would seem that these are on the low side as far as temps go, and that there should be some more room for me to safely ramp it up. But if I go 1200, ATI shows a ton of pixel errors, and at 460 there are enough errors to make me jittery about using that setting.

Maybe I just got a card that for what ever reasons won't clock as high? Any thoughts?


Oh, at 450/1150 it scored right around 7500 on 3DMark05. A far cry from some of the scores in here, I was shooting for 8000. Still, I'm happy enough with performance of the computer. I know that this is a great score for a computer that only cost me $1500 bucks. These e1750's are the best bang for the buck in the laptop arena that I have found...by far.
