The nVidia 7800 Series Performance Survey

[HeavyH20]

Ooooo.
I like the new colors for cooling solution!
Very easy to read and pretty as well.

Gotta' use those Power Point skills I have polished over the years

 

[HeavyH20]

meh, it's depressing being at the bottom of that chart! this week when i get my new cooler from Stasis, we'll see if I can bump up those megahurtz a little bit

Wait until a few more GT results show up. I think you may find yourself more in the middle of the pack. Unless, of course, the only people posting on this thread are the ones getting better than average OC results.

Make: BFG
Model: 7800gt
Driver: 77.76 (whatever came off the CD)
BIOS rev: 6/23/05 (Not 100% on like a specific revision)
Stock clocks: 425 / 1050
Coolbits Detect: I got a few different ones but.... core avg around 500 memory 1200
Usable OC: I think to keep temps below 70 for me the core should be 486. I am able to raise ram as much as I want without affecting temps too much. 486/1225 got me 7961 whereas 486/1230 got 7950. I'll do a few more runs tomorrow to see. The best I got was 513/1230 which got 8248 however temps spiked to 71C.
Idle temp: avg 50
Cooling method: stock

I'll try to make a better post tomorrow. I haven't been able to play any games yet, but I'll do it tomorrow. I'll find a link to my ORB thingy too.

Haha! So true bro. But then we can always say we're "more confident" about our occasional artifact/crash ratio than those ^^ there. I haven't seen the stasis 7800 cooler on the site yet... Am I missin' somethin?

Very pretty! Def like the colors for mods. I'm the green one holding the chart together at the bottom

This is on air at room temp of 82.8F. I have a Lian-Li PC-V1000 case also.

Good? Bad?

With that ambient, those temps are quite good. Nothing to worry about there!

 

[510kut]

just a question... how bad is it if I spike above 70? Like sometimes it'll hit 70-72 when playing games. Its pretty warm out right now so I might bring it down some more until summer is over.

That is not that bad if it is a spike here and there. If you started hitting the 80's, maybe then I would look at better cooling.

And that's why I'm looking into better cooling... mine tops out at 80c

 

[510kut]

ahh ok... in that case maybe I'll bump it back up to 513/1230 or atleast find the fps plateu that anandtech talks about I idle pretty high but it only jumsp to about 72 max I believe.

 

[dR.Jester]

Damn now I know why they say "every card is unique". My BFG won't even go close to or even above 500 core.

470 isnt too bad for a GT though But i know what you mean, i just about scraped 500 out of my GTX, which is nice, but i wish i had that 551 core clock

Oh well, at least my memory clock is good

77.77
Stock clocks: 450/1250
Usable OC: 490/1300
Idle temp: 37C
Cooling method: Stock + 92mm panaflo fan on heatsink.

 

[HeavyH20]

Looks like the GT cards operate on a different frequency than 27MHz. Or, they may, but the root frequncy appears to be 5 MHz shy of the norm. So, instead of a jump at 473, it occurs at 478 on the GT. This may be simply that coolbits is reporting wrong, or there is a different frequency multiplier.

Also, having looked at variety of GT BIOS's, it looks like there is a difference on how they operate there, as well. Some have a single performance level default in the BIOS (XFX, BFG). Others, like the eVGA have 2 or 3 levels. I wish I had a GT to check verify this infromation. I might have to pick one up.

Maybe someone with a GT could confrm a couple of things with RivaTuner. If you could, run the rivtuner monitor in the background, and report on the coolbits settings and do a 3Dmark05 run. It would be interesting to see.

Here are the common clocks I see via 3DMark05

438/1002 - which is suppsoed to be 400/1000 - nVidia reference
425/1053 - which is 425/1050 - somehow 3Dmark05 picks up the root clock instead of the 472 the card bumps to for BFG GT OC cards
450/1053 - which is 450/1050 - XFX, Leadtek - detects root setting of clock correctly in 3DMark05.
486/1070 - which is 445/1050 - eVGA

 

[Jodiuh]

Gar!!! The previous 68gt from leadtek came with a honking heatsink, right? So I ordered a leadtek hoping they'd do something other than reference...and splinter cell ct

Leadtek laughin' at Jod... There's some comments on xtremesystems too.

Actually, that Leadtek looks rather cool (pun intended). The bigger heatsink is what many had thought would show up on the 7800 Ultra. The Quadro cards use this heatsink, so it makes sense that it would move over to the gaming version, as well. And, the 490/1250 clocks are almost the same as the eVGA KO and XFX EE aside from the slightly lower memory clocking. Looks good to me!

Whe you get it, it would be interesting to see how cool it runs and the headroom on the core and memory. Let us know how it works!

Looks like that "booster" fan works quite well. What is your ambient temp? And, how much louder did the fan make the card?

 

[pduan87]

Aww, had to drop my core from 504 to 498. It looped 3dmark05 for hours and BF2 was also fine but I played some source today and got some flashing.

 

[dR.Jester]

I hate it when that happens.

Same sh*t happened to me with BF2 on my eVGA 6800GT. Everything else ran like a champ at the OC I was running and then when BF2 was loaded up, all the trees and bushes were stretched.

 

[Russ]

I would wait at least a week to make sure the card is really healthy before any mods. That way, if it fails, warranty is not an issue. Most electronics fail within 72 hours of constant use if they are defective.

its still working fine.

 

[HeavyH20]

Can it do 500? That is the next threshold on the 7800 core clock. Personally, I run mine at a nice cool 490/1350 for 24x7 operation. It idles at 38C and loads to 42C at that clock. Pushing the card at or very near its limit coudl eventually cause a premature death of the card. I like to give myself a good pad betwen what the card's potential is, and what I operate the card.

Also, some games hit certain features that others do not, heating up the core or exceeding a component capacity. Games with HDR and SM 3.0 can heat up a card fast.

Thanks to everyone contributing to this thread, and to HeavyH20 for maintaining the chart!


EDIT: to include idle temp.

 

[HeavyH20]

No problem GoldenTiger. It is interesting to see what these cards are capable of.

BTW, has anyone seen the new eVGA 7800 GT CO? It is a limited release that you can pre-order, so it does not qualify for the step-up. It soundslike it is built as requested. It comes withe a copper heatsink and clocked to 470/1100 out of the box. Here is a link:

Yeah, it is interesting to see what these cards can do. I saw the new card, but I just got my "plain" GT . It's pretty nice-looking, though!

 

[HeavyH20]

I am putting together somes statistics based on the survey. So far, I have the Top three usable OC for the GTX Cards. More to follow.

Hey ...good call ..now if you could just get Russ to send me his card ..then my life would be complete .

or you could send me yours.

I did some playing around with coolbits today. Didn't try to increase the ram speed much b/c I figured it isn't cooled as thouroghly as the core. Would this be correct? Do you guys usually get a good OC over what coolbits detects on ram?

Installed 78.03 drivers too. Coolbits redetected 487 instead of 489. I tried increasing it over 500, but it didn't like that. Most of the time it said failed the test. However, strangely one time it accepted 507, but not 500-506 or higher than 507. Then when I retested 507 it said it didn't work! So I'm at like 498 or something now. Should I do anything differently?

Coolbits does detect a good safe OC. It allows some room for thermal issues. But,if you watercool or modify the stock cooler for better performance, you can run it a little higher.

The pad is around 25 MHz on the core and 30 to 40 MHz on the memory. If it is properly cooled, you can run the memory at or near the limit. Personally, I don;t push my card too hard. I run it at 490/1350 as my "stock" setting via a new BIOS.

 

[peacetilence]

My coolbits auto detection is exactly 489/1.28. The same speed as a KO. I wonder if they built in some certain limit because I was able to take it up to 530/1.3 (didn't try and go any higher on the memory) until Coolbits detection came back as failed.

Almost to the KO spec. But, most KO's will exceed 490 and 1300 on the coolbits. Need a little bit of headroom. The interesting thing about the KO, is that the regular eVGA GTX OC's just as well and in some cases, better. Seems the only real difference is the upgraded cooler. But, I would need more KO samples to get a real feel for what they are capable.

I've got one! I've got one

Finally, an ASUS! Well, it is not surprising since eVGA, BFG, and XFX dominate the nVidia market in the US. Leadtek, Gainward and ASUS are big in Europe. But, I was hoping to see at least a few examples. Thanks for the post!

Anyone have an ASUS GTX TOP??
