View Full Version : Asus 8800 GTS Memory Clock Running at half speed?!

Hello,
I have been having performance problems with my Asus 8800 GTS card and not been able to fix them so far.

However I just installed the beta of Everest that handles the 8800 card and noticed that the Real Clock entry for the Memory Bus seems to indicate that it is running at half normal speed!!

Is my card defective, or can this be caused by something else? Lack of power perhaps?

If anyone has any idea it would be greatly appreciated!

Those numbers are fine. Just like all DDR, it's physical clock is 396 while in actuallity, it's running at 792. Nothing to worry about.

I take it you missed this from his post?

I tried the program myself but it never gave me any information on bus etc. I would say it's a glitch with the program.

I have noticed that other peoples cards report:

Real Clock 792 MHz (DDR) (original: 792 MHz)

and mine report:
Real Clock 396 MHz (DDR) (original: 792 MHz)

so its defenitely a difference. Also, notice that my BW is only 30GB/s instead of 60GB/s.

You need the beta version of Everest from their webpage to get 8800 info.

[EDIT] I just got a reply from the excellent people at lavalys makers of Everest. It was a bug in the in the beta version of the software I used that made my card show up with incorrect speed. It has been fixed, and the new version shows correct results, so there was nothing wrong with my card!

Everything else looks fine except the numbers above.
The Real Clock is definitely only showing as half of what it should be.
And the bandwidth is showing as extremely low also, it should be double that.

You stated that you had performance issues with your card , but even if the beta version of Everest was showing an incorrect reading it shouldn't have any effect on the card's performance.

I'm hoping that the poor performance I experience are due to either my old i925 INTEL motherboard, or my single core P4 3.6GHz.
I've bought a new 680i MB and a C2D processor so hopefully that'll fix my problems. Otherwise I'll be back here looking for more suggestions... :)

No, it is a DRIVER bug, anything higher than the 97.02's can indeed cause two of the three memory controllers to run at half speed. Read more here:

Because of this I am still running the 96.89 drivers.

Small trick for G80 owners:

You can use programmable GPUProbe plugin to monitor clocks of all 3 memory clock domains (2 of which are affected by bug of 97.28+ drivers and constantly run @ BIOS defined 400MHz clock). To add an ability of 3 memory domain clocks monitoring replace .\Plugins\Monitoring\GPUProbe. cfg file with the following text:

Then go to monitoring -> Setup -> Plugins and enable GPUProbe.dll plugin. After doing that, you'll see Memory clock \ doman 0, Memory clock \ doman 1 and Memory clock \ doman 2 graphs reflecting state of each of 3 memory clock generators.

Hmm... that probably explains why Everest reported the lower speed. It happened to check one of the low speed mems. I'll suggest that they check all mem speed in the next version.

I don't think it explains my poor performance though since it looks like it affects everone?

3DMark06 score of 4900... :(

Around 1000 on cpu and 2200 on SM2/SM3. The SM2 SM3 scores seem to be around 1000 below what other people with my cpu type are reporting for each gfx.

I would'nt even worry about it if you have a 680i SLI and a Core 2 Duo ready to go ,because you will see a big performance increase,well depending on how far you overclock it.I have a Core 2 Duo E6600 clocked at 3.6gigs at 1.35v on my Evga 680i SLI ,well right now I am running it on my Asus 650i SLI and I get 15152 with two running in SLI.Plus some of them programs read the memory in fouths ,at least AtiTool used to.That what it looks like it is doing since all of your other clocks are reporting right .

Check with Everest and see what speed the PCIe slot is running at, is it running at x16?, you'll find it in the GPU tab here......

Yep, its at x16.

I actually suspect my power supply, a Hiper 580W type-R.
It does provide 20A+18A in a dual rail config, but I've found out that the 12V rails only handle 360W together on this PSU. Also, the cables for the PSU only handle approx 6.5A each, so that probably limits the power supply for the card.

I'll send the PSU back and get myself a Corsair HX620W instead that doesnt have the silly 360W limit on the 12V rails.

Let me know how you go with the Corsair HX620W as I was thinking of trying one out also.
