8800 Overclocks: Post yours

Just like to see what kind of OC ppl are getting on their 8800s

Mine...

Inno3D 8800gts 320
Core 513 -> 600
Mem 800 -> 900
Using Riva Tuner

Havent pushed it as im getting the fps i want... for now.
But it seems it will oc as well or better than any factory oc card.
Oc's a LOT better than the 1950xt

PNY 8800GTS 320MB
Core 500/625
Ram 800/1000

Wish I could do some kinda Vmod on these but I hear the Vmod on this card is negligible. Have got it to run at 650MHZ in ATI tool with no errors for 30mins but it crashes BF2 after about 15 or so minutes of playing.

Ya I hear that I had a X1950XT before this and that thing didn't overclock real well compared to this and it hit extreme temps. At 700mhz (75MHZ OC) on that thing it would hit 96C in BF2. Fan fully blaring and a crap load of hot air coming out. This 8800GTS hit 75C max at a 125MHZ OC and barely has any heat output or noise compared to what I am use too. Thats why I wish I could Vmod it. It seems to have lots of potential.

8800GTS 320mb

core @ 652Mhz
mem @ 1000Mhz

runs stable in everything but battlefield 2142, and with my cheep fan mod it beryl gets over 60c. iv have the core up to 690Mhz but i can only run the desktop anything 3d and i get artifacts

edit:it will run 3dmark with no crashes upto about 670Mhz on the core the ram tops out at 1084Mhz

Hmmm... While you are at it, can you post some benchmarks/fps at stock and OC frequencies?

I am interested in an 8800 myself, and have seen conlficting info on the impact of core clock increases.

thanks!

Should I push mem to 1000? seems like that works for you guys. Any missing textures/crashes?

Reply to beta-catenin

eVga 8800gtx KO @ 621 core / 1000 mem.

Of course that is stock for the card. I had pushed it up to 663 fairly stable(occasional artifacts but no crashing), but the visible difference in FPS was not there. I just couldn't tell from looking at it, so i said what the heck, leave it at stock(621) for now, until something comes out that I can't max out at stock. 8)

Probably I will try pushing it again when Crysis finally comes along.

My MSI 8800GTX is completely stable at 630/1030, up from the stock 575/900. Stock cooler and no volt modding. That would be pretty much the same speed as the Ultra wouldn't it? 3DMark06 score went up from 11,000 to 11,800, a 7% increase.

I've ran 3dmark06 at 630/1000 with no problems.
My regular game profile is 612/1000.
I'm still very happy with my cooler running/low power desktop profile of 130/260.

I've posted this somewhere else before but worth mentioning again for anyone oc'ing 8800's is that the overclocks happen in steps and don't always reflect what you think you are running.

from 554 to 571 = 567
from 572 to 584 = 576
from 585 to 603 = 594
from 604 to 616 = 612
from 617 to 634 = 621
from 635 to 661 = 648
from 662 to ??? = 675

So we can see that when you set your core to 600 MHz, it actually works at 594, which is exactly one percent less than what you requested.

Instead, these numbers show the value of base clock that triggers the SP clock change and its value.

565=1350
589=1404
611=1458
634=1512
657=1566
681=1620

The same principle also applies when clocking the memory:
from 897 to 908 = 900
from 909 to 927 = 918
from 928 to 940 = 936
from 941 to 958 =945
from 959 to 985 = 972
from 986 to 1003 = 999
from 1004 to 1116 =1008
from 1117 to 1035 = 1026
from 1036 to 1048 = 1044

These are for the gtx and I don't know if it applies the same for gts. Someone with a gts and Everest could always look into it.

i could be rong but to my knolage there is a moltiplyer that works like this

core speed * 2.3 = shader speed, but you set the shader speed with memory speed which uses a moltplyer to

memory speed * 1.5 = shader speed

you have to keep within these molitplers to keep the card stable also the core only goes up in 25Mhz increments

i could be wrong but thats what i know

also i know i spelled moltiplyer rong and knolage sorry don know how to spell them and my spell checker isn't picking them up

edit: and by the looks bf is the real gfx tester

You got me curious as to what the impact would be so I did some testing. I don't know the best test to try it out but I tried anyhow. The numbers support what you are saying.

I ran 3dmark06 canyon flight at 604/1000, 616/1000, 617/1000.
The first two speeds will result in the same core speed but should still see some benefit from what you are saying. It did.
I ran each test 3 times and the results are consistent and outside the margin of error.

@ 604- 47.371, 47.302, 47.247--Avg. 47.306
@ 616- 47.861, 47.901, 47.807--Avg. 47.865
@ 617- 48.097, 48.112, 48.118--Avg. 48.109

This basically suggests that the big steps are important to be mindful of but there are still gains to be had in between them,(though smaller).

-In the first step the core is bumped 1.99% but the performance goes up only 1.16%. This is because the effective core speed never changed.

-In the second step the core went up only .16% but the performance went up .53%.

Nice work NO1sFanboy

Im gonna have a play around some more when i some time.

Also as a side note... been getting some strange performance with STALKER... sometimes gets 10-15 fps on a new load, even with no dynamic lighting, all i need to do is go into gfx settings (not even change ne thing) and juts click 'use' and it shoots up to 40-60ish again. Odd. Farken game is soo bugged.

Just did a bit more tweaking on the card... it's running DiRT stable at 655/1075 now. I'm beginning to like this card, methinks...

From what i experienced in Rivatuner. The 8800gts is similar. If you go into Targer Adapter and then customize, then hardware monitor.Then oc it with rivatuner or ati tool. You will see that i goes up in incraments.

That is a serious overclock Mugs, what app are you using? Nvidia are holding back the voltage on us me thinks.

Reply to nick_000000

Coolbits to test the settings, Nibitor to keep them in the VGA BIOS (I've now flashed that card about four times, would've been two but I had a cockup).

Yes, they are holding back on the volts. In Nibitor it offers me the option of ?.?V, 1.3V (selected), 1.2V and 1.1V. I'm not risking that ?.?V, I feel safer with a 10KΩ variable resistor on the relevant points.

I'll post more details later - boss just walked in ...

I have a superclcoked 8800gts and i installed rivatuner because i wanted to overclock it a little bit. Rivatuner is showing that it is running at 58C! Is that normal? My Q6600 w/120 extreme never goes above 49C @3.0ghz(Orthos x2). Wont the temperatures rise even more when im in game? 3dmark06 completes fine though. 11k with the graphics at stock. Vista 64bit

It's normal, set the fan speed to 100% if you want it to stay at lower temps. Mine is idling at 52-60 with 100% fan speed and 55-65 with default fan speed.
I overclocked mine to 650/1000, no artifacts, got 11015 points in 3d mark paired with a E6420@3Ghz.

Just Flashed my 8800GTX to 626/1000 not quite 770/1200 :ouch: but at least its a boost from 575, aint up to doing hardware mods yet . May go up higher 650/1100 but see how the temps work out first.

Don’t worry there is plenty of cooling, I like to have the fans turned right down though for quietness I have a Watercooled setup on my E6700 and 8800GTX :whistle: but I felt the tubes last night and they felt quite warm. I don't want too go to 650/1100 and find I have to turn the fans all the way up. Spose I am being a bit fussy if there :pfff: .

I have a 2x120mm rad (top) and a 1x120mm rad (front) so no more room in my stacker for any more. I have already modded the top to accomidate the 2x120mm rad, maybe outside the case but I don't really want that too messy. I bumped up the 8800 last night and flashed it to 650/1000 & 1500 for shaders. I think I will keep it like that for the default 1.3 voltage otherwise the 8800gtx might start to get a bit :fou: . I think I will be happy with 650 though compared to the default 575 :pfff: .

Reply to nick_000000

Mine's on 1.34V, after vmods. That's the lowest I could get it while remaining stable, any lower and I have to drop to 730 on the core.

Mem's probably good to go further. We'll see later on.

If I get the 640mb version, I jsut hope to overclock it to 650/1000.

Theoreticly by overclocking to 770/1080, you should have better on paper stats then a GTX. Would be interesting to see if that was reflected in-game.

I overclocked my 8800GTS 320MB using NVidia's tool.

I have the profile set at

640 Core / 990 Memory

The Nvidia Monitor is showing it actually at

648 Core / 999 Memory.

Just ran 3DMark06 again, got 10070.

Oh and I forgot to add, the card hit the low 70's temperature while 3DMark06 was running. And is sitting in the mid 60's right now without games. So about 6 or 7 degrees hotter than the stock overclocked speeds this card came with.
